- the protective device for covering the shafts of the plug contacts can comprise a spring-mounted protective cover device, which has a protective cover designed at least partially as a hollow cylinder for each plug contact as a protective element. wherein the protective cover device further comprises a base element, and the protective covers are rigidly mechanically coupled to one another by means of the base element, so that they can be moved together on the shafts of the plug contacts.
- a respective protective cover can be designed essentially as a hollow cylinder. The respective protective cover is essentially incompressible along the longitudinal direction of the plug contacts.
- the protective device has compressible protective bodies as protective elements for covering the shafts of the plug contacts along the longitudinal direction of the plug contacts, which are rigidly mechanically coupled to one another by means of a base element, wherein an end region of a respective protective body can be displaced while compressing the protective body in order to expose the shaft of the plug contact.

- Each respective protective body has a through opening in which the respective plug contact is arranged.
- a respective compressible protective body can be elastically compressible so that it can develop an elastic restoring force in the compressed state.
- a protective body can be a foam body, for example. If necessary, a common foam body can form both protective elements. This means that the foam body can be implemented as a common membrane/foam body or two individual cylinder membrane/foam bodies.
- the power plug can have a guide device for guiding the protective device along the longitudinal direction of the plug contacts, whereby an uneven displacement of the protective elements on the plug contacts can be counteracted by means of the guide device due to the base element tilting on a guide element of the guide device. An uneven movement would occur if one protective element is moved further in a unit of time than the other protective element.
- the base element can have a canting element.
- the housing of the base element can have a canting element.
- the power plug may have a counter-tilting element.
- the canting element can be designed to complement the counter canting element.

- the entire counter-tilting element can run parallel to the plug-in direction.
- a clear width of the canting element and a width of the counter canting element parallel to the clear width can be dimensioned such that the base element with the canting element can slide on the counter canting element when the base element is pushed further into the connector housing along the plugging direction.
- the clear width and the width are the same size.
- the tilting element can slide on the counter tilting element.
- a force acts on the base element, whereby the force acts at an angle to the plugging direction that is not equal to 0° or not equal to 180°, this force can tilt the base element.
- This tilting can cause the tilting element and the counter tilting element to tilt with each other, so that the force does not cause the base element to move further into the plug housing along the plugging direction and the plug contacts remain in the remain in the protective device and cannot protrude from it in a contactless manner.
- the tilting leads to self-locking if one of the protective covers is pushed further than the other protective cover.
- the guide element no longer runs perpendicular to the base element, so that the base element causes two opposing forces on the guide element, their lines of action spaced apart from one another, the magnitude of which increases with increasing angle of the guide element, starting from a right-angled position of the base element in relation to the guide track.
- the inner guide element (protective cover carrier plate, base element, referred to below as 42) can be moved radially onto the spring guide and further advancement can be prevented.
- An additional ripple or blockage tilt protection can provide a subsequent second or additional level of protection (back-up protection).
- the guide device can be arranged between the plug contacts. If the protective elements are designed as compressible protective bodies, the guide device in the base element of the protective contact plug can have guide elements that are arranged on the side of a plug contact facing away from the other plug contact.
- At least one of the protective elements can have a receiving volume for one of the plug contacts, the diameter of which runs transversely to the plugging direction in the direction of the free ends of the protective elements can be removed.
- the receiving volume can be conical, for example.
- a minimum diameter of the receiving volume can essentially correspond to an external diameter of one of the plug contacts. Tilting the protective device can also cause at least one of the protective elements to jam with one of the plug contacts and thus create a self-locking effect.
- the inner diameter of at least one of the protective elements can be minimal at its free end and essentially correspond to the outer diameter of one of the plug contacts. This can prevent small or thin conductors, such as a wire, from being easily inserted into one of the protective elements at the insulated end area of one of the plug contacts. In this way, an appropriate degree of protection, for example IP2x or comparable, can be achieved.
- the guide elements on the side of the compressible protective bodies facing away from the base element can be rigidly connected to one another by means of a pressure plate.
- the pressure plate or the end areas of the compressible protective bodies are guided by means of the guide device.
- the compressible protective elements can be made of foam. Furthermore, the materials used for the protective elements can have water-repellent material properties, flame retardancy, halogen-free if necessary, class B1/B2, and a density in the range RG>15 kg/m3, and/or a compression hardness in the range SH ⁇ 20 g/cm2.
- a further embodiment of the power plug provides that the power plug has a housing as a protective device, with a protective cover between the housing and the A relative movement can be carried out between the plug contacts so that the plug contacts can be moved into and out of the housing.
- the housing can be made of flame-retardant material.
- the power plug can have a drive element with which a movement of the plug contacts out of the housing can be effected when a manual actuating force is introduced.
- the drive element can be mechanically firmly connected to the plug contacts and protrude from the housing so that a manual force on the drive element causes a displacement of the plug contacts so that at least their free end areas and in some areas the shafts of the plug contacts protrude from the housing and can be inserted into the sockets of a power outlet.
- the power plug can have a blocking device with at least one movable actuating element which can be moved by an optional protective contact of the socket when the power plug is inserted into a socket and can thus remove a blockage of a relative movement between the housing and the plug contacts.
- a blocking device with at least one movable actuating element which can be moved by an optional protective contact of the socket when the power plug is inserted into a socket and can thus remove a blockage of a relative movement between the housing and the plug contacts.
- the plug contacts are housed in the housing so that they are electrically protected. If the protective contact of the socket moves the operating element, for example if it is pressed in, the blocking effect is removed and the plug contacts can be moved out of the housing and into the socket's socket sockets.
- the power plug can have a spring device which, when the spring device is tensioned, directly or indirectly causes a spring force on the plug contacts and/or on the housing, so that the plug contacts are automatically moved into the housing, provided they are not fixed by sockets of a mating plug, for example a socket or a coupling.
- the power plug can have a protruding protective contact pin (e.g. CEE 7/5) which, when inserted, releases the electrical connection of the plug contacts to the device.
- the power plug can have a fixing device with which the plug contacts can be fixed in a position moved out of the housing. This prevents the plug contacts from automatically moving into the housing and consequently moving out of the plug sockets when plugged into the socket and possibly with low clamping forces of the socket's plug sockets due to the spring force of the spring device.
- the base element can have at least one receiving opening and, for example, two receiving openings for receiving the spring guide.
- the at least one receiving opening can extend completely through the base element in the plug-in direction.
- the at least one receiving opening can be completely surrounded by the material of the base element transversely to the plug-in direction.
- the at least one receiving opening can be arranged between the protective elements. If several, for example two, receiving openings are provided, these can be arranged one behind the other in a direction transversely to the plug-in direction in which the protective elements are spaced apart from one another.
- the spring guide of the plug can be designed as a pin extending in the plugging direction, onto which the spring device, for example a spiral spring, can be inserted.
- the base element has only one receiving opening.
- the diameter of the receiving opening can be smaller than the diameter of the spring device, so that the material of the base element that at least partially surrounds the receiving opening can serve as a support or stop for the spring device.
- the diameter of the The receiving opening can essentially correspond to the diameter of the pin, so that the base element with the receiving opening can slide and tilt on the pin.
- the base element can have one of the receiving openings for each of the guide beams. At least one of the receiving openings can be designed to be complementary to the guide beam that it receives, so that the base element with the receiving opening can slide and tilt on the guide beam.
- the base element can have a support bridge remaining between the receiving openings, which can rest against the spring device.
- the support bridge can have a larger contact surface with the spring device than the material of the base element that at least partially surrounds the receiving opening.
- arc fault protection device which is also referred to as a fire protection switch.
- arc fault protection device may be, for example, an AFDD (“Arc Fault Detection Device”) or an AFCI (“Arc Fault Circuit Interrupter”).
- the power plug may be designed to be electrically or galvanically connected to an arc fault protection device and/or to a residual current circuit breaker.
- the power plug can be a protective contact plug.
- each of the described embodiments can comprise a protective circuit with a first switching element, for example a relay or a semiconductor switch such as a triac, and a second switching element, for example a relay or a semiconductor switch such as a triac, wherein when the first switching element is energized - if a correct connection exists - this first switching element forms a current path to the second Switching element closes so that it is energized, and the second switching element thereby opens the current path via a second switch to the first switching element and in doing so closes an electrical circuit.
- the protective circuit can be part of the mains connection circuit or correspond to it.
- the protective circuit can be the phase position detection device or have it.
- a current flows from a live phase to the first switching element. This is then activated so that it closes a current path to the second switching element.
- the second switching element also switches so that it in turn de-energizes the first switching element, but in doing so closes a current path to an external contact, such as a socket. In this way, a current flow can be realized from the power plug via the plug contacts into a socket.
- the second switching element does not switch either, so that it does not close a current path to an external contact, such as a socket.
- a first contact of the second switching element and a first signaling device can be arranged in series in a first current path between a live phase of the power plug and a neutral conductor of the power plug.
- the first signaling device can be a light element, such as a red lamp. Accordingly, if there is no correct contact, a signal is output by the first signaling device, which signals that no correct contact has been made. Appropriate electrical dimensioning can ensure that no upstream protective devices (e.g. residual current circuit breakers) are triggered.
- a second contact of the second switching element and a second signaling device can be arranged in series in a second current path between the live phase and the neutral conductor.
- the second signaling device can be a green lamp. If the contact is made correctly, the second signaling device will emit a corresponding signal.
- the reverse polarity protection can also be implemented without a signaling device in the correct direction of contact.
- a hand switch can be arranged in series with the second signaling device, which is designed, for example, as a normally closed contact, so that the signal is output by means of the second signaling device only when the hand switch has been closed.
- the design embodiments described ensure that there is protection against electric shock. This enables user-friendly use of the power plug on a power source.

- Figure 37 an embodiment of a plug contact of the power plug, the free end of which is designed for connection to the pin head, in a first side view
- Figure 38 the embodiment of Figure 37 in another side view
- Figure 39 a perspective view of the embodiment of the plug contact of Figure 37, which is provided with the pin head of Figure 34,
- Figure 40 another embodiment of the network connection circuit
- Figure 41 yet another embodiment of the network connection circuit.
- the power plugs 1 shown have in common are that they have several and in particular at least two plug contacts 20, which are held in a base body 11 or lead through a base body 11. Furthermore, they each have a housing 10 for covering.
- the plug contacts 20 extend parallel to one another along their respective longitudinal directions 21 and accordingly each form a shaft 22.
- This shaft 22 is fixed on one side with a fastening end region in or on the base body 11, so that a respective shaft 22 has a free end region 24 for insertion into a socket of a power outlet.
- the power plug 1 shown in the figures has 30 different embodiments with regard to its protective device.
- the power plug 1 shown in Figures 1 to 4 comprises a protective device 30 which is designed as a spring-mounted protective cover device 40.
- This protective cover device 40 comprises protective covers 41 which are essentially designed in the shape of a hollow cylinder as a protective element 31 for each plug contact 20, which are only indicated in Figure 1.
- Figure 5 shows the protective cover device 40 in its entirety in a side view. Here it is clearly visible that the individual protective covers 41 are firmly connected to one another by means of the base element 42. Figure 6 shows this in a frontal view.
- Figure 7 shows in frontal view that the protective covers 41 penetrate the base body 11 through corresponding holes or openings formed there.
- Figure 8 shows the base body 11 in a perspective view, wherein a receiving space 12 for receiving the protective covering device 40 which can be moved in the base body 11 can be seen.
- Figure 9 shows the power plug without housing from the side.
- the protective contacts 26 of the power plug are clearly visible here.
- a spring device 90 in the form of a compression spring can also be seen here, which in the embodiment shown here sits on the shaft 24 of a plug contact 20.
- the protective cover device 40 shown in Figure 5 can be moved in the direction of the fastening end region 23 of the plug contact 20 against a spring force of this spring device 90.
- the plug contact 20 or its shaft 22 is thereby exposed and can be electrically contacted.
- the force required for this can, for example, be applied by a socket of a power outlet when inserting the power plug 1 into the socket.
- the spring device 90 causes an opposite displacement of the protective cover device 40 so that it again covers the shafts 22 of the plug contacts 20, as shown in Figure 1.
- the first embodiment of the power plug 1 shown in Figures 1 to 9 is not limited to the guidance of the spring device 90 on a plug contact 20, but the spring device 90 can also be arranged and guided on an extra guide element instead of being guided on a plug contact 20.
- a second embodiment of the power plug and its individual parts is shown in Figures 10 to 13.
- Protective elements 31 of the protective device 30 are here compressible protective bodies 50 which surround a respective plug contact 20 or its shaft and thus electrically insulate it.
- Such a protective body 50 can be made from a foam material, for example.
- This pressure plate 53 is held by means of a guide device 60 and guided in a base element 42.
- guide elements 61 run parallel to the longitudinal direction of the protective bodies 50 or also of the plug contacts 20 and are slidably mounted in the base element 42.
- the power plug 1 If the power plug 1 is plugged into a socket, a force from the socket acts on the pressure plate 53, which causes the pressure plate 53 to move together with the guide elements 61 arranged on it in the direction of the base body 11.
- the protective bodies 50 are compressed along this direction. During compression, the volume of the protective bodies 50 can be accommodated at least partially in the receiving space 12 of the base body 11.
- the elastic restoring forces of the protective bodies 50 are so low, preferably less than 150 N and advantageously less than 80 N, that these elastic restoring forces are not sufficient to automatically release the power plug from the socket and/or to prevent it from being pushed out on its own.
- the shafts 22 of the plug contacts 20 can be exposed and electrically contacted with a respective socket.
- FIG. 14 to 21 relate to a third embodiment of the power plug 1.
- the plug contacts 20 are movable in relation to the housing 10 along the longitudinal direction 21 of the plug contacts 20.
- Figures 14 and 15 show a situation in which the plug contacts 20 protrude from the housing 10
- Figures 16 and 17 show a situation in which the plug contacts 20 are accommodated in the housing 10 and accordingly do not protrude.
- the power plug 1 can comprise a blocking device 80 with a movable actuating element 81, which can be moved by a protective contact 26 of the socket when the power plug 1 is inserted into a socket.
- the mechanical connection between the protective contact 26 and the actuating element 81 is not shown here for reasons of clarity.
- the protective contact 26 is subjected to a radial force and moved slightly radially inwards. This movement of the protective contact 26 is transferred to the movable actuating element 81. This removes a blocking effect on the part of the blocking device 80, so that a relative movement 110 can take place between the housing and the plug contacts 20. Accordingly, the plug contacts 20 can now be extended, as shown in Figure 18. The plug contacts 20 extend out of a front plate 82. After this movement has been carried out, the shafts 22 of the plug contacts 20 are therefore no longer covered by the housing 10 and can be electrically contacted by sockets of a socket.
- the plug contacts 20 can be extended by introducing a manual actuating force into a drive element not shown here.
- the frictional forces occurring between the socket and a respective plug contact 20 can hold the plug contact 20 in the extended position.
- the first switching element is located in a third current path 140 between a live phase 150 and an optional protective conductor 170.
- the second switching element is located between the live phase 150 and a neutral conductor 160. If the power plug 1 has a protective conductor 170, the power plug 1 can be a protective contact plug.
- the current-carrying phase 150 can also be referred to as the outer conductor.
- the first switching element is energized and closes the current path to the second switching element via the first switch, so that the latter is energized.
- the second switching element opens the current path via the second switch to the first switching element, thereby closing an electrical circuit. If the current path between the current-carrying phase 150 and the first switching element is not closed, there is also no current flow from the current-carrying phase 150 to the first switching element. This is accordingly not actuated, so that it does not close a current path to the second switching element and the second switching element is not energized. Accordingly, the second switching element does not open the current path via the second switch to the first switching element and does not close a circuit.
- a first contact KS21 of the second switch and a first signaling device 180 are arranged in series in a first current path 120 between the live phase 150 of the power plug and the neutral conductor 160 of the power plug.
- a manual switch 200 is arranged in series with the second signaling device 190, which is designed as a normally closed contact, for example, so that the signal is only output by means of the second signaling device 190 when the manual switch 200 has been closed.
- the manual switch 200 can be a mechanically actuated switch or a capacitively actuated switch or a switch that can be actuated in another way.
- the relay K1 with the relay switch KS1 is replaced by a triac.
- an RC element which can also be referred to as a snubber, is connected in parallel to the triac.
- Figure 24 shows a further embodiment of the network connection circuit.
- the same reference numerals are used for elements that correspond in function and/or design to elements of the embodiment shown in Figure 23. In the following, only the differences from the embodiment shown in Figure 24 are discussed.
- the mains connection circuit of Figure 24 additionally has an ohmic resistor R1 connected directly upstream of the triac on the input side.
- Figure 25 shows a further embodiment of the network connection circuit.
- the same reference numerals are used for elements that correspond in function and/or design to elements of the embodiment shown in Figure 24. In the following, only the differences from the embodiment shown in Figure 25 are discussed.
- the mains connection circuit of Figure 25 is designed not only to detect incorrect polarity, but also to correct it.
- the mains connection circuit also has another switch KS3 with a triac and an optional RC element, which can be referred to as a snubber.
- a resistor R3 is connected directly upstream of the triac on the input side.
- the mains connection circuit also has another switch in the form of a triac, which is connected in parallel to the triac of the switch KS1 and which is connected directly upstream of a resistor R2 on the input side.
- Figure 26 shows an embodiment of a grid connection device.
- a converter Q is connected downstream of a source G, for example a direct current source, such as a photovoltaic system or a wind turbine.
- the converter Q can be connected or can be connected to a battery storage device or another energy storage device with which direct current can be stored.
- an arc fault protection device 300 and one of the arc fault The reverse polarity protection circuit 400 connected downstream of the protective device 300 is shown, which can optionally both be accommodated in a common housing of the network connection device.
- the reverse polarity protection circuit 400 can be an integral part of the power plug 1.
- the reverse polarity protection circuit 400 can have or be one of the circuits of the embodiments of Figures 22 to 25.
- the housing with the arc fault protection device 300 and the power plug 1 can be designed and/or provided separately from the converter Q and can optionally be electrically connected to it by a plug connection.
- the protective devices 400 and 300 could also be designed in one housing.
- Figure 27 shows a further embodiment of the network connection device of Figure 26, in which the protective devices for the mains plug are implemented in different housings.
- the same reference numerals are used for elements that correspond in function and/or design to elements of the embodiment shown in Figure 26. In the following, only the differences from the embodiment shown in Figure 26 are discussed.
- the inner diameter of at least one of the protective elements 41 can be minimal at the free end of the protective elements 41 and essentially correspond to the outer diameter of one of the plug contacts. This can prevent even small or thin conductors, such as a wire, from being easily inserted into one of the protective elements at the insulated end region of one of the plug contacts.
- the receiving volume V can be limited by an inner side 94 of the at least one protective element 41, so that the inner side 94 can be formed complementarily to the possibly conical receiving volume V.
- An angle W between the inner side 94 and the base element 42 and in particular between the inner side 94 and a front side of the base element 42 from which the at least one protective element 41 protrudes can be less than 90°.
- the angle W can be up to 80°, 85° or 89°.
- the inner side 94 of the protective element 41 can be aligned at an angle to the plugging direction that can be non-zero and can be up to 10°, 5° or 1°, for example.
- the at least one protective element 41 can have a constant wall thickness, so that an outer side 95 of the at least one protective element 41 can run parallel to the inner side 94.
- the wind strength of the at least one protective element 41 can change in the plugging direction, i.e. away from the base element 42, and for example increase.
- the at least one protective element 41 can have a cylindrical outer shape instead of a conical outer shape.
- Figure 31 shows the embodiment of Figures 29 and 30 in a frontal view, in which the protective elements 41 point out of the plane of the drawing parallel to the plugging direction.
- the base element 42 can have an optional tilting element 92a.
- the tilting element 92 and the optional tilting element 92a can be arranged symmetrically to one another and, for example, on opposite sides of the base element 42.
- the tilting element 92 and the optional tilting element 92a can be designed identically.
- the optional tilting element 92a can be shaped differently and, for example, wider and/or deeper than the tilting element 92.
- Anti-twisting protection that can be provided by the different design of the tilting element 92 and the optional tilting element 92 can also be provided by only providing one tilting element 92.
- the base element 42 can have a support bridge 95 remaining between the receiving openings 93, which can serve as an abutment for a spring device.
- Figure 32 schematically shows an embodiment of the housing 10 of the power plug in a perspective view.
- the housing 10 has a contact receiving volume U, which is designed to accommodate the plug contacts 20 and the protective device 30.
- the housing 10 of the power plug can have at least one counter-tilting element 96 which is designed to interact with the tilting element 92 of the protective device.
- the tilting element 92 can be designed to complement the counter-tilting element 96.
- the counter-tilting element 96 can be designed as a web or as a projection that can engage in the tilting element 92, for example as a groove or recess.
- the counter-tilting element 96 can extend along the plug-in direction and have a free end pointing transversely to the plug-in direction, for example into the interior of the plug housing 10. The entire counter-tilting element 96 can run parallel to the plug-in direction.
- a clear width of the at least one tilting element 92 and a width of the counter tilting element 96 parallel to the clear width can be dimensioned such that the base element 42 with the tilting element 92 can slide on the counter tilting element 96 when the base element 42 is pushed further into the connector housing 10 against the plugging direction.
- the clear width and the width are the same size.
- the tilting element 92 can slide on the counter tilting element 96. However, if a force acts on the base element 42, whereby the force acts at an angle to the plugging direction that is not equal to 0° or not equal to 180°, this force can tilt the base element 42. Due to this tilting, the tilting element 92 and the counter tilting element 96 can tilt with each other, so that the force does not cause any movement of the base element 42. against the plugging direction further into the plug housing 10 and the plug contacts 20 remain in the protective device 40 and cannot protrude from it in a contact-proof manner.
- the housing 10 of the power plug can have a spring guide arranged in the contact receiving volume U.
- the spring guide of the housing 10 can be designed as a pin extending in the plugging direction, onto which a spring device 90, for example a spiral spring, can be plugged. In this case, it can be sufficient if the base element 42 has only one receiving opening 93.
- the diameter of the receiving opening 93 can be smaller than the diameter of the spring device 90, so that the material of the base element 42 that at least partially surrounds the receiving opening 93 can serve as a support or stop or abutment for the spring device 90.
- the diameter of the receiving opening 93 can essentially correspond to the diameter of the pin, so that the base element 42 with the receiving opening 93 can slide on the pin and possibly even tilt if a force tries to move the base element 42 non-parallel to the plugging direction.
- the base element 42 can have one of the receiving openings 93. At least one of the receiving openings 93 can be designed to be complementary to the guide bar 97, 98 that it receives, so that the base element 42 with the receiving opening 93 can slide on the guide bar 97, 97 and possibly even tilt if a force tries to move the base element 42 non-parallel to the plug-in direction.
- Figure 33 shows the embodiment of Figure 32 schematically in a front view, in which a plug face of the housing 10, which is not yet provided with the plug contacts 20 and the base element 42, points out of the plane of the drawing in the plugging direction.
- the base element 42 can have an optional counter-tilt element 96a.
- the counter-tilt element 96 and the optional counter-tilt element 96a can be arranged symmetrically to one another and, for example, on inner sides of the housing 10 facing one another.
- the counter-tilt element 96 and the optional counter-tilt element 96a can be designed identically.
- the optional counter-tilt element 96a can be shaped differently and, for example, wider and/or deeper than the counter-tilt element 96.
- Anti-twisting protection that can be provided by the different design of the counter-tilt element 96 and the optional counter-tilt element 9a can also be provided by only providing one counter-tilt element 96.
- the guide bars 97, 98 together flank a spring holder F into which the spring device 90, for example a spiral spring or at least a disc spring, can be inserted.
- the guide bars 97, 98 can guide the spring device 90 along the plug-in direction such that unwanted movements of the spring device 90 transverse to the plug-in direction are prevented by the guide bars 97, 98.
- Contact bushings 99 of the housing 10 for the plug contacts 20 can flank the spring holder F and/or the guide bars 97, 98.
- the contact bushings 99, the spring holder F and/or the guide bars 97, 98 can be arranged one behind the other along a direction transverse to the plug-in direction.
- Figures 34 to 36 show schematic views of an electrically insulating pin head 100, which can be made, for example, from an electrically insulating plastic and/or rubber.
- the pin head 100 can have a mounting opening 101 with an open end. Opposite the open end, the pin head 100 can have a closed end.
- An outer side of the pin head 100, which has the closed end and points away from the mounting opening 101, can be at least partially curved and, for example, hemispherical or angled or conical or tapered.
- the mounting opening 101 can have a locking element, for example a taper running parallel to the open end.
- the pin head 100 can also be called a plug contact cap.
- Figures 37 and 38 show an embodiment of a contact pin 102 which can provide one of the plug contacts 20 with the pin head 100.
- a free end of the contact pin 102 can have a mounting element 103 for mounting the pin head.
- the mounting element 103 can be designed to be complementary to the mounting opening 101 at least in sections and can have a counter-locking element for the locking element, for example a projection which runs around the mounting element 1030 at least in sections transversely to the longitudinal direction of the contact pin 102.
- Figure 39 shows the plug contact 20 with the pin head 100 of Figures 34 to 36 in a state mounted on the contact pin 102, in which the mounting element 103 is inserted into the mounting opening 101.
- a diameter S of the essentially cylindrical contact pin 102 corresponds to the diameter of the pin head on its side facing the contact pin 102.
- the open end of the mounting opening 101 can be arranged in the side facing the contact pin 102.
- the side facing the contact pin 102 can be referred to as the base side of the pin head 100.
- the diameter of the pin head 100 can decrease away from the side facing the contact pin 102.
- Figure 40 shows a further embodiment of the network connection circuit.
- the same reference numerals are used for elements that correspond in function and/or design to elements of the embodiment shown in Figure 23. In the following, only the differences from the embodiment shown in Figure 24 are discussed.
- Figure 40 shows an example of a further circuit diagram of an electrical reverse polarity protection circuit 400 according to the invention, for example for a power plug 1.
- the reverse polarity protection circuit 400 which can also be referred to as a power connection circuit, has three contacts L, N, PE for the input and three contacts L', N', PE' for the output.
- the power plug 1 is correctly plugged in, when the live phase of a mating plug, such as a mains socket, is connected to conductor 150 of reverse polarity protection circuit 400.
- the respective phases at the input and output are then the same.
- a signaling device 190 such as an array of photodiodes, lights up and shows the correct contact state.
- the signaling device 190 may not light up or light up differently and no live phase is transferred from the input contact conductor L to the output contact L', the current flow is interrupted.
- an inverter of a direct current source such as a photovoltaic system or another energy supply system, can be or will be connected to the L', N', PE' contact of the output.
- the nest plug can be connected to the L, N, PE contacts of the input.
- circuit diagram shown as an example in Figure 40 has three circuits 410, 420, 430. Two of the circuits 410, 420 connect the current-carrying conductor 150 and the neutral conductor 160 to one another. A third circuit 430 connects the current-carrying conductor 150 to the protective conductor 170.
- the second circuit 420 can comprise a two-way switch, such as the relay KS2, several resistors, the signaling device 190 and a diode connected in series with the signaling device 190, wherein the signaling device 190 can have photodiodes connected in series with one another. As soon as the live phase of the mains voltage is correctly applied, the signaling device 190 can signal that the mains plug 1 is correctly plugged in.
- the first circuit 410 can connect the current-carrying conductor 150 to the neutral conductor 160 via a diac of an optocoupler and via a switch, such as an electronic switch or a switch with an electromechanical drive, such as the relay K2.
- the electromechanical drive can be protected from voltage pulses or short-term voltage pulses in a parallel circuit by a suppressor diode and a resistor.
- the third circuit 430 can connect the current-carrying conductor 150 to the protective conductor
- the third circuit 430 and the second circuit 420 can be switched to live.
- the photodiode in the optocoupler can then also light up. The light emitted by the photodiode is received in the optocoupler by the diac of the optocoupler. The diac of the optocoupler can then switch the first circuit 410 to live.
- the diac of the optocoupler When the diac of the optocoupler receives a signal, current can flow through the electromechanical drive that controls the two-way switch. When current flows through the electromechanical drive, the two-way switch can be switched such that the input L is coupled to the output L' and the input L and the output L' have the same phase. As soon as the electromechanical drive switches the two-way switch, the flow of current through the second circuit 420 and through the third circuit 430 can be stopped. Thus, the signaling device 190 can go out.
- Figure 41 shows, by way of example, yet another circuit diagram of an electrical reverse polarity protection circuit 400 according to the invention, for example for a power plug 1.
- the circuit in Figure 41 is designed to adapt the phase position of the voltage applied to the power plug 1 to the phase position of the power socket and to switch over if necessary.
- the reverse polarity protection circuit 400 shown in Figure 41 has three contacts L, N, PE for the input and three contacts L', N', PE' for the output. In contrast to the circuit diagram in Figure 40, the circuit diagram in Figure 41 does not have an array of photodiodes. In the circuit diagram shown in Figure 41, instead of signaling incorrect insertion, the phases incorrectly applied to the input contacts L, N are swapped. The correct phases are then applied to the output contacts L', N', thus correcting incorrect insertion of the mains plug 1.
- circuit diagram shown in Figure 41 has five circuits 410, 420, 430, 440, 450. Three of the circuits 410, 420, 430 can connect the conductor for the live phase 150 to the neutral conductor 160. A fourth Circuit 440 may connect conductor 150 to protective conductor 170. A fifth
- Circuit 450 may connect conductor 160 to protective conductor 170.
- the first circuit 410 can connect the conductor 150 to the conductor 160 via a first diac of a first optocoupler and via a switch, such as an electronic switch or a switch with an electromechanical drive, such as the relay K2.
- the switch can be protected from voltage pulses or short-term voltage pulses in a parallel circuit by a first suppressor diode and a resistor.
- the second circuit 420 can connect the conductor 150 to the conductor 160 via a diac of a second optocoupler and via another switch, such as an electronic switch or a switch with an electromechanical drive, such as another relay K3.
- the second switch can be protected from voltage pulses or short-term voltage pulses in a parallel circuit by a second suppressor diode and a second resistor.
- the fourth circuit 440 and the fifth circuit 450 can thus be switched to be live, so that either the photodiode of the first optocoupler or the photodiode of the second optocoupler is switched to be live or activated. Which photodiode is activated depends on which conductor is the live phase.
- the fourth circuit 440 can be or become current-carrying in addition to the third circuit 430.
- the current flow in the fourth circuit 440 emits light from the photodiode of the first optocoupler, which is received by the diac of the first optocoupler.
- the diac of the first optocoupler can thus switch the first circuit 410 to current-carrying so that, for example, the first electromechanical drive switches.
- the first electromechanical drive can in turn actuate two first two-way switches 480 in such a way that the current-carrying phase is transferred from the input conductor L to the output conductor L'.
- the connection between the conductor 150 and the conductor 160 via the third circuit 430 can be interrupted by the first electromechanical drive. The phases of the input contacts and the output contacts are therefore the same.
- the fourth circuit 440 can be switched to conduct current, but there is no significant current flow between the normal conductor 150 and the protective conductor 170.
- the photodiode of the first optocoupler therefore does not emit any light, so that no light is received by the diac in the first optocoupler, which in turn means that the first circuit 410 is not switched to conduct current.
- the first electromechanical drive therefore does not switch the two first two-way switches 480 mentioned above. If the live phase of the mains voltage is applied to the conductor 160, then the fifth circuit 450 can be switched to live.
