- Pyrotechnically operated fuse elements for electrical circuits are known, for example, from DE 42 11 079 A1 and DE 44 22 177 A1.
- an electrical circuit is interrupted by a separating element if a pyrotechnic charge is ignited when an overcurrent flowing in the circuit to be protected, the current strength of which is greater than a predetermined threshold value, is ignited.
- the combustion gases released are used to drive the separating element through the current conductor.
- the invention has for its object to provide a pyrotechnic switching element for electrical circuits with which electrical circuit can be switched on due to the ignition of a pyrotechnic charge.
- the invention proposes a pyrotechnic switching element for electrical circuits, which is provided with
- At least one current conductor which has two current conductor sections which are arranged separated from one another by an intermediate space
- At least one bridging element that can be moved as a result of the ignition of a pyrotechnic charge, which is arranged separately from at least one of the two current conductor sections in an initial position before the pyrotechnical charge is ignited and is in electrical contact with both current conductor sections in a bridging position after the pyrotechnic charge is ignited .
- an electrically conductive bridging element is moved by ignition of a pyrotechnic charge in the direction of the two spaced-apart ends of two current conductor sections and brought into electrical contact with them.
- the bridging element In the starting position of the pyrotechnic switching element before the pyrotechnic charge is ignited, the bridging element is arranged at least separately from one of the two current conductor sections. In the bridging position after the pyrotechnic charge has been ignited, the bridging element is in electrically conductive contact with both current conductor sections.
- the two current conductor sections which are electrically connected to one another via the bridging element, are regarded as parts of a current conductor.
- the pyrotechnic switching element With the help of the pyrotechnic switching element, several current conductors or several pairs of current conductor sections can be bridged simultaneously or at different times. A bridging element is then assigned to each current conductor.
- the bridging element is pressed into the gap between the two current conductor sections in the bridging position, in particular by wedging.
- the wedging or, more generally, the interference fit of the bridging element and the current conductor in the bridging position creates an electrical contact between the bridging element and the current conductor sections that has no appreciable contact resistance. This is particularly advantageous if the current conductor is connected to electrical load circuits for high currents.
- the interference fit of the bridging element and the current conductor can be implemented in a wide variety of ways.
- the bridging element it is conceivable for the bridging element to have wedge surfaces which come into contact with the current conductor sections when the bridging element is "shot" between them.
- Such wedge surfaces could, however, also be formed, for example, on the end faces of the current conductor sections, the bridging element then being able to have rectangular contact surfaces for contacting the wedge surfaces of the current conductor sections.
- the bridging element in the form of a ball or as a bolt, the round circumferential surfaces of which come into contact with the current conductor sections or the end faces thereof if the bridging element is shot into the space between the two current conductor sections.
- the bridging element in a movable manner in a receiving space of a housing, the combustion gases released when the pyrotechnic charge is ignited penetrating into this receiving space in order to advance the bridging element in the manner of the piston of a pneumatic or hydraulic piston-cylinder unit.
- the bridging element it is also conceivable for the bridging element to be held by a holding element, which in turn can be driven pyrotechnically and is movably guided in a receiving space of a housing. In both cases it applies that the two current conductor sections also protrude into the receiving space of the housing.
- a holding element is provided for the bridging element, it is advantageous if this holding element has an opening for receiving the bridging element, the bridging element projecting laterally beyond the holding element in the direction of the extension of the two current conductor sections.
- the bridging element is exposed on the two sides of the holding element opposite the end faces of the current conductor sections in order to come into mechanical and electrical contact with the current conductor sections when the pyrotechnic switching element is in its bridging position.
- the bridging element is separated from a carrier element by means of a pyrotechnically driven separating device, and that the separate part of the carrier element (bridging element) is used for contacting the two conductor sections.
- the pyrotechnic charge is used both to separate the bridging element from the carrier element and to shoot the bridging element into the space between the two current conductor sections or to contact the bridging element with the two current conductor sections.
- the carrier element can be fixed in a simple manner in a housing, wherein it extends through a receiving space inside the housing, in which the opening device is also located.
- the separating device is arranged on the side of the carrier element facing away from the current conductor sections.
- the separating device When it moves as a result of the ignition of the pyro-technical charge, the separating device accordingly first strikes the carrier element in order to separate a part (called a bridging element) from its separating section, which part is moved by the separating device against the current conductor sections in the further course of the advancing movement.
- a bridging element a part
- the carrier element is expediently formed in one piece, its separating section having an extension which is greater than the distance between the two conductor sections and having a cross-sectional area which is smaller than in the region of the carrier element outside the at least one separating section.
- the bridging element is designed as a predetermined breaking point of the carrier element, which is advantageous in that the forces for separating the bridging element from the carrier element are then reduced. This in turn is advantageous with regard to the dimensioning of the pyrotechnic switching element and in particular the pyrotechnic charge.
- the separating device is preferably provided with a punching tool for separating the bridging element from the separating section of the carrier element.
- the carrier element thus has, so to speak, the function of a die for punching out the bridging element, which, however, is part of the carrier element before being removed.
- the at least one separating section of the carrier element is designed as a recess made in the outer surface thereof.
- This depression is expediently located in the side section of the outer surface of the carrier element facing the punching element.
- the flanks of the recess can then serve as a guide for the punching tool, which then expediently already in the recess in its initial position, from which it can be moved as a result of the ignition of the pyrotechnic charge to separate the bridging element from the carrier part is immersed.
- the pyrotechnic switching element according to the invention can advantageously be used both for safety shutdown of a first circuit and for switching on a second circuit if the carrier element is designed as a current conductor. Then the current conductor is used on the one hand to provide the bridging element for switching on the second circuit connected to the current conductor sections and on the other hand to switch off the on the Current conductor connected to the first circuit. If this double function is assigned to the pyrotechnic switching element, the pyrotechnic charge is ignited depending on whether the current flowing in the first circuit, which is connected to the current conductor providing the bridging element, is greater than a predefinable threshold value.
- the separated bridging element which is brought into electrical contact with the current conductor sections and thus serves to switch on the circuit connected to them, can then be used for (additional) signal activation.
- the pyrotechnic switching element according to this embodiment of the invention thus has the function of a cut-off protection with additional signal activation.
- the carrier element is used as a current conductor and its at least one separating section is formed by reducing the cross-section, care should be taken to ensure that this reduction in cross-sectional area does not result in any significant voltage drop, i.e. does not lead to any appreciable increase in resistance in the conductor.
- the cross-sectional area of the current conductor in the separating section is less than 50%, preferably less than 30%, most preferably between 5% to 15% and in particular 10% of the cross-sectional area of the current conductor outside the separating section.
- the at least one current conductor is made in one piece, thereby avoiding electrical contact zones which can change with regard to their contact resistance as a result of temperature, manufacturing tolerances, moisture or corrosion.
- the moving mass can be reduced, which enables lower material thicknesses and the use of inexpensive plastic materials.
- the size of the pyrotechnic fuse element is relatively small.
- the pyrotechnic security element has only a few items.
- the pyrotechnic charge need only be designed to be low.
- the carrier element serving as a current conductor for the bridging element can also have two separating sections. These separating sections are at a greater distance from one another than the distance between the two conductor sections to be connected to one another via the bridging element. Otherwise, the separating sections can be designed as described above. In this development of the invention, the middle part between the two separating sections is separated from the carrier element / current conductor in order to serve as a bridging element for the two current conductor sections of the other current conductor.
- the two separating sections are designed as recesses which are introduced into the outer surface of the carrier element facing the current conductor sections. It is also advantageous here if the two flanks of the depressions arranged on both sides of the central part of the carrier element are designed as wedge surfaces, so that the central part is designed in the manner of a trapezoid when viewed from the side. These wedge surfaces can then be used to press the separated central part (bridging element) by wedging between the end faces of the current conductor sections when the pyro-technical switching element is in its bridging position.
- the carrier element is formed in several parts and has at least two carrier element sections with mutually facing ends, between which the bridging element is caused by friction in mechanical parts and electrical contact with the support element sections is arranged, the bridging element forming the separating section of the support element.
- the bridging element is held by frictional engagement with the mutually facing ends of the two carrier element sections.
- These two carrier element sections expediently overlap, their ends having through bores which are aligned with one another and through which the bridging element extends.
- the bridging element is preferably designed as a particularly cylindrical bolt, the axial ends of which are received in the through bores of the carrier element sections.
- a press fit is particularly suitable as a friction fit.
- the support element and the bridging element are formed in several parts by means of the separating device between the support elements and driven between the two current conductor sections in order to electrically connect them to one another.
- the separating device has a pyrotechnically driven impact element, by means of which the bridging element is separated out of the mechanical connection with the two carrier element sections and moved out in order to be driven between the two current conductor sections.
- the support element can advantageously be designed as an electrical safety cut-off current conductor, from which the bridging element held with frictional engagement can be removed if the threshold current is exceeded by means of the separating device. Even when the bridging element is clamped on the carrier element or between its two sections, the pyrotechnic switching element can be used to switch off a first circuit and to switch on a second circuit when the pyrotechnic charge is ignited.
- the impact element expediently consists of an electrically non-conductive material. If the two carrier element sections are the sections of a current conductor which is to be interrupted in the event of the pyrotechnic charge being triggered, it should be reliably prevented that after the bridging element has been removed, the butt element taking up its space between the separating element sections does not close leads to an electrical connection of the two separating element sections.
- a pyrotechnic switching element with a bridging element held between two carrier element sections can be used in a simple manner to implement a two-way switch.
- the bridging element In the starting position, the bridging element is located between the first current conductor, viewed in the direction of movement of the bridging element, and the second, i.e. middle conductor. These two current conductors form the carrier element sections for holding the bridging element. In this starting position of the bridging element, an electrical current can flow via the first and the middle current conductor.
- the bridging element When the pyrotechnic charge is triggered, the bridging element is brought out of engagement with the first current conductor by the abutting element lying against it, in order to bring the middle current conductor into connection with the last current conductor viewed in the direction of movement of the bridging element. Now the middle conductor and the last conductor are mechanically and thus electrically connected, as a result of which the two-way switching function is implemented. During its movement, the bridging element should be guided between the current conductors in order to always dive into the mutually aligned bores of the ends of the current conductor sections.
- the ends of the current conductor sections are embedded in a housing made of non-conductive material, which has a cavity which is flush with the bores of the ends of the current conductor sections and has a diameter or cross-section in which the bridging area ⁇ element is arranged.
- the inner walls of the bores of the ends of the current conductor sections thus form sections of the inner wall of the cavity.

- the figures 2 and 4 sectional views according to the arrows II-II and IV-IV of Fig. 1 and Fig. 3.
- the pyrotechnic switching element 10 is shown in Figs. 1 and 2 in its switched-off state and in FIGS. 3 and 4 shown in its switched-on state.
- the pyrotechnic switching element 10 has a housing 12 made of a particularly electrically insulating material, in which a 14 is designed as a receiving space for a holding element 16.
- a current conductor 18 extends through the receiving space 14 and has two current conductor sections 20 which are aligned with one another and arranged at a distance from one another. Both current conductor sections 20 extend with their mutually facing contact ends 22 into the cavity 14.
- the holding element has a continuous opening extending in the direction of the course of the current conductor 18, in which a bridging element 26 made of electrically conductive material is accommodated.
- the bridging element 26 stands, as can be seen in particular in FIG. 1, at both ends of the opening 24 above the holding element 16 and, in particular when viewed from above, projects beyond the contacting ends 22 of the conductor sections 20 in its projecting end sections in its projecting end sections from the FIGS. 1 to 4, the bridging element 26 has the shape of a round bolt, the longitudinal axis of which extends transversely to the longitudinal extent of the current conductor 18.
- the cylindrical outer surface of the round-bolt-like bridging element 26 thus projects laterally beyond the holding element 16.
- a pyrotechnic charge 28 with an electrical ignition element (not shown) and electrical feed lines 30.
- the holding element 16 moves in the direction of the arrow 32, as a result of which the bridging element 26 in Direction on the contacting ends 22 of the conductor sections 20 is moved.
- the combustion gases generated during the ignition of the pyrotechnic charge 28 give the holding element 16 such a high kinetic energy that the bridging element 26 held by the holding element 16 is pressed into the intermediate space 34 between the contacting ends 22 of the current conductor sections 20.
- the forward movement of the holding element 16 is limited by the boundary wall 36 of the cavity 14 running transversely to the direction of movement (32), against which the front end of the holding element 16 abuts in the direction of movement. This situation is shown in FIGS. 3 and 4.
- the driving in of the bridging element 26 into the intermediate space 34 with the creation of an interference fit between the bridging element 26 and the contacting ends 22 of the current conductor sections 20 ensures a bounce-free and reliable electrical bridging of the two current conductor sections 20.
- the frictional connection between the bridging element 26 and the current conductor sections 20 guarantees a negligible transition resistance.
- Copper in particular, is a suitable material for the bridging element, which is a comparatively soft, electrically highly conductive material.
- Figs. 5 and 6 show another exemplary embodiment of a pyrotechnic switching element 40 for load circuits in the switch-on and switch-off positions.
- this pyrotechnic switching element 40 the function of a safety shutdown of another circuit is also realized when the load circuit is switched on.
- the pyrotechnic switching element 40 has a housing 42 made of, in particular, electrically insulating material.
- a cavity 44 is formed in the housing 42, through which two current conductors 46, 48 extend in different planes. While the first current conductor 46 is continuous, the second current conductor 48 has two current conductor sections 49, the mutually opposite contacting ends 50 of which extend into the cavity 44.
- the punching tool 52 has, in particular, the shape of a piston, preferably made of plastic.
- the central part 54 which can be separated from the first current conductor 46, is delimited in the longitudinal extent of the first current conductor 46 by two groove-like depressions 60.
- the two depressions 60 are introduced in the outer side 62 of the first current conductor 46 facing the second current conductor 48.
- the first current conductor 46 has a substantially smaller cross-sectional area than in its remaining area. This reduction in cross-section is dimensioned such that there are no significant voltage drops in the current conductor 46, that is to say the depressions 60 do not have an electrical disadvantage on the circuit connected to the first current conductor 46.
- the depressions 60 are introduced into the first current conductor 46 transversely to the longitudinal extent thereof and extend over the entire width of the current conductor 46.
- the depressions 60 form two separating sections 64 in which the central part 54 emerges from the first current conductor 46 when acted on by the punching tool 52 ⁇ can be separated.
- the two flanks 66 adjoining the central part 54 run obliquely, being inclined towards one another.
- the central part 54 is given a wedge shape which is dimensioned such that the central part 54, at its front end facing the second current conductor 48, has an extension — viewed in the longitudinal direction of the second current conductor 48 — that is equal to the distance between the contacting ends 50 Current conductor sections 49 of the second current conductor 48.
- the mode of operation of the pyrotechnic switching element 40 will be briefly discussed below.
- the pyrotechnic charge 56 is ignited.
- the combustion gases released thereby give the punching tool 52 a force to move through the cavity 44 in the direction of the arrow 68.
- the punching tool 52 acts on the central part 54 of the first current conductor 46 and separates it at the separating sections 64 from the first current conductor 46.
- this transports the central part 54 in the direction of the second current conductor 48 in order to drive the central part 54 into the intermediate space 70 between the contacting ends 50 of the current conductor sections 49 of the second current conductor 48.
- the central part 54 Because of the wedge-shaped design of the central part 54, it is pressed with the current conductor sections 49, so to speak. As a result, there is no significant contact resistance between the central part 54 and the current conductor sections 49.
- the central part 54 therefore takes on the function of a bridging element. 72 for electrically bridging the two current conductor sections 49 of the first current conductor 46.
- a further exemplary embodiment of a pyrotechnic switching element 80 with a cut-off protection function for a first circuit and switch-on function for a second circuit is to be described.

- the front end of the separating element 92 is immersed in a depression 98 in the current conductor 86.
- This depression 98 which in the case of the exemplary embodiment is a groove with a rectangular cross section and extends over the entire width of the current conductor 86, represents the separating section 100 of the current conductor 86, in the area of which the current conductor 86 by means of the separator device 18 can be severed.
- the depression 98 is introduced into that part 102 of the outer surface of the current conductor 86 which faces the separating device 88.
- the separating element 92 is advanced through the separating section 100 of the current conductor 86 into the receiving space 104.
- this receiving space 104 also serves to receive that part 106 of the current conductor 86, within its separating section 100, which is separated by the separating element 92.
- the separating element 92 thus stamps the part 106 out of the separating section 100 of the current conductor 86.
- This separated web part 106 is pressed by the punching element 102 against the ends 108 of two contact pins 110 projecting into the cavity 84 and held in this position.
- the web part 106 thus represents the bridging element 114 for bridging the contact pins 110.

- the blind hole 124 is closed on its open end face by a closure piece 126.
- the closure piece 126 can, for example, be glued in, clamped in or welded in.
- a pyrotechnic charge 128 or an electronic ignition element with feed lines 129 In the closure piece 126 there is a pyrotechnic charge 128 or an electronic ignition element with feed lines 129. When ignited, the charge 128 generates a compressed gas in the blind hole 124 which is used to move a push element 130 made of electrically non-conductive material and designed as a bolt .
- three current conductor sections are embedded in the housing 122 and are arranged in the axial extension of the blind hole 124 one after the other overlapping ends.

- the above- bridging element 154 thus ensures the electrical connection of the first conductor section 132 to the second conductor section 138.
- the overpressure which arises in the region of the blind hole 124 below the bridging element 154 can escape via the relief bore 150.
- the sealing plug 152 is ejected or destroyed, as a result of which an indicator or display function is implemented which indicates that the pyrotechnic switching element 120 has triggered.
- the ejection element 120 is located after the ignition between the first conductor section 132 and the second conductor section 138, but without being immersed in the through hole 142 of the second conductor section 138. Rather, in this through-bore 142 there is the end of the bridging element 154 on the face side, which in the starting position according to FIG. 11 was immersed in the through-bore 136 of the first current conductor section 132.
