Definitions
- Terminal for connecting an electrical cable
- the invention relates to a connection terminal for connecting an electrical line according to the preamble of claim 1.
- connection terminal includes a housing that has a plug-in opening into which the electrical line can be inserted for connecting to the connection terminal.
- a contact element is arranged on the housing and has a contact section for electrical contact with the electrical line.
- a spring element is also arranged on the housing, which has a clamping leg that is adjustable relative to the housing, which is designed to act on the electrical line in a clamping position for contact with the contact section and is removed from the contact section in a release position compared to the clamping position.
- the clamping leg is locked in the release position directly or indirectly relative to the housing and is thus held in its release position. If the clamping leg is in the release position, an electrical cable can be connected to the connection terminal by inserting it into the plug-in opening.
- a trigger element serves to interact with the electrical cable when it is inserted into the plug-in opening to release the clamping leg from the release position.
- connection terminal realizes a spring-loaded connection, in which the electrical line is clamped in the connected position with the contact element under the elastic spring action of the spring element and is therefore electrically connected to the contact element.
- a spring element in the form of a tension spring is provided, which pulls a connected electrical line into contact with an associated contact element by elastic spring action and thus creates a clamping connection between the electrical line and the contact element.
- the electrical line is pushed through an opening in the clamping leg when it is attached and clamped in the connected position between the clamping leg and the contact element.
- a latching device is provided, via which the clamping leg is latched in a release position relative to the housing.
- the locking device is activated triggered and thus the latching is canceled, so that the clamping leg is moved out of the release position and thereby the electrical line is jammed with the contact element.
- a tool for example a screwdriver, can be placed on the connection terminal and thereby exert a force on the clamping leg become.
- connection terminals known from DE 10 2019 135 203 A1 and DE 10 2020 104 140 A1 there is an actuating element in the form of a so-called pusher. provided, which can be pressed into the housing of the connecting terminal in order to act on the clamping leg and to move the clamping leg into its release position.
- the actuating element is spring-biased relative to the housing of the connecting terminal via a tension spring in the form of a compression spring.
- an actuating lug is arranged on the actuating element, which is hooked to a fastening section of a holding element in the actuated position of the actuating element.
- test tap in order to tap a voltage at the connection terminal by placing a testing tool on the connection terminal.
- a test tap is often designed in such a way that the testing tool can be brought into contact with the spring element forming the clamp leg using a test syringe in order to test the voltage on the connection terminal in this way.
- test tap that allows the voltage to be tapped even if no electrical line is yet connected to the connection terminal and the clamping leg of the spring element is in the release position. If the clamping leg is in the release position and the connection terminal is delivered in this state, for example by a manufacturer, the clamping leg has no contact with the contact element, so that under certain circumstances (particularly if the spring element is separated from the contact element on the housing). is supported) no voltage can be tapped.
- a connection terminal known from DE 10 2020 104 138 B4 a test opening is formed on a housing into which a test tool can be inserted for contacting a current bar within the housing.
- the object of the present invention is to provide a connection terminal which makes it possible to easily tap a voltage at the connection terminal for testing purposes by using a testing tool.
- the contact element comprises a contacting device for contacting an associated electrical assembly, a first leg extending from the contacting device and forming the contact section, and a second leg extending from the contacting device and forming a tapping section for electrical contacting with a testing tool.
- the electrical line is electrically contacted with the electrical contact element in that when the electrical line is inserted into the plug-in opening, the clamping leg acts on the electrical line and loads it resiliently in the direction of contact with the contact element.
- the clamping leg of the spring element can be deflected elastically, for example by a tool or by actuating an actuating element, in order in this way to move the clamping leg into a release position in which a space in the area of the plug-in opening is released and thus the electrical cable can be inserted into the plug opening in a substantially powerless manner or a connected electrical cable can be easily removed from the connection terminal.
- the clamping leg is held in the release position relative to the housing. This can be done by directly locking the clamping leg relative to the housing or by indirect locking, for example via an actuating element.
- the clamping leg can lock with the trigger element in the release position.
- an actuating element can lock with the trigger element or with a latching device on the housing.
- the clamping leg (directly or indirectly via the actuating element) is in position relative to the release position held in the housing so that a user can insert an electrical cable into the plug opening in a simple, essentially powerless manner and thus connect it to the connection terminal.
- the triggering element is used to release the clamping leg from the release position in order to automatically release the clamping leg from the release position when the electrical cable is inserted and thus to transfer it to a clamping position in which the electrical cable inserted into the plug-in opening is electrically contacted with the contact element of the connecting terminal. Because the trigger element is deflected when the electrical cable is inserted, the connecting terminal closes automatically when the electrical cable is inserted. The result is a simple connection process, with reliable contact between the line and the contact element.
- connection terminal in which the clamping leg of the spring element is held in position relative to the housing in the release position and which can be triggered automatically via a trigger element when an electrical cable is inserted, can be delivered by a manufacturer, for example, with the clamping leg in the release position.
- a tap section is formed on the contact element in the connection terminal, which enables electrical contact with a testing tool and thus a voltage to be tapped the contact element is allowed for testing purposes.
- the tapping section is formed on a leg protruding from a contacting device of the contact element.
- the contacting device is used to contact an associated electrical assembly.
- a further leg extending from the contacting device forms the contact section for contact and contacting with a connected electrical line.
- the test tapping takes place on the contact element and is therefore independent of a position of the clamping leg of the spring element. Because the test tap is not made on the spring element, it is particularly irrelevant whether the spring element is in contact with the contact element or the clamping leg is in the release position in which the clamping leg is removed from the contact section.
- the tapping section on the contact element can therefore also be used in the Release position of the clamp leg a voltage can be tapped at the connection terminal when the spring element is supported on the housing independently of the contact element and is therefore not electrically connected to the contact element.
- the testing tap can be provided on the connection terminal where a testing tool can be attached to the connection terminal in a space-saving manner.
- a connected electrical line contacts the contact element via the first leg, which forms the contact section.
- a testing tool can be contacted with the contact element via the second leg in order to tap a voltage for testing purposes.
- a contacting device is formed between the first leg and the second leg, via which the connection terminal can be connected, for example in a plug-in manner, to an associated electrical assembly, for example a mating connector.
- the contact section extends flatly along a plane which is spanned by a plug-in direction in which the electrical line can be plugged into the plug-in opening, and a transverse direction pointing transversely to the plug-in direction.
- the contact section is therefore designed to be flat and is aligned parallel to the plug-in direction in which an electrical line can be plugged into the connection terminal.
- the tapping section extends obliquely to the insertion direction.
- the contact section and the tap section are thus aligned along different directions on the housing. Due to the oblique extension, the tapping section can point in particular towards a test opening which is formed on the housing in order to enable the insertion of a test tool into the housing.
- a test opening provided on the housing for inserting a test tool can in particular be designed such that the test tool can be inserted into the test opening along a vertical direction.
- the tapping section preferably extends obliquely to the vertical direction.
- the vertical direction can, for example, point perpendicular to the plugging direction in which an electrical line is inserted
- Plug opening of the housing can be inserted for connection to the connection terminal, so that the test section is aligned both obliquely to the vertical direction and obliquely to the plugging direction.
- the tapping section engages with an end remote from the contacting device in an engagement opening on the housing and is supported on the housing above it.
- the tapping section thus extends from the contacting device and is supported on the housing at a remote, free end.
- a bending load on the tapping section is thus reduced by supporting load forces applied by a testing tool on the housing and discharging them into the housing.
- the contact section has an end remote from the contacting device pointing in the direction of the plug-in opening. Both the tapping section and the contact section thus, in one embodiment, have a free end extending from the contacting device.
- the contact element can be designed as a sheet metal element, for example in the form of a stamped and bent part, in which the contact section, the contacting device and the tapping section are formed by sections of the contact element that are bent towards one another.
- the contacting device is designed by a contact socket for plug-in connection to the associated electrical assembly.
- a contact socket for example in the form of a so-called contact tulip, can have, for example, contact lamellas via which the contacting device can be connected to an associated electrical assembly in the form of a mating connector.
- a contact element of the mating connector can be inserted between the contact lamellas of the contact socket in order to establish an electrical connection between a plug connector, of which the connection terminal is part, and the mating connector.
- the spring element is designed as a tension spring.
- the clamping leg of the spring element is designed to pull the electrical line into contact with the contact element by spring force.
- an opening can be formed on the clamping leg, for example, through which the electrical cable can be passed when inserted into the plug-in opening of the housing in order to Triggering the clamping leg from the release position to pull the electrical cable into clamping contact with the contact element.
- the spring element can be designed as a compression spring.
- the clamping leg is designed to press the electrical line into contact with the contact element by spring force. When inserted into the plug-in opening, the electrical line enters a space between the clamping leg and the contact element, whereby after the clamping leg is released from the release position, the clamping leg acts on the electrical line and presses it into contact with the contact element.
- the spring element can, for example, have a support leg, via which the spring element is supported on the housing and held in position on the housing.
- the clamping leg can be deflected elastically relative to the support leg, with the clamping leg being deflected in the release position in such a way that the spring element is elastically tensioned and the clamping leg is moved out of the release position in an elastically prestressed manner after being released from the release position.
- the support leg can, for example, engage in a support opening on the housing and is supported on the housing above it.
- the spring element is therefore attached to the housing independently of the contact element and is therefore not directly electrically connected to the contact element if the housing is made of an electrically insulating material, in particular a plastic material.
- the triggering element has a triggering leg which is designed to interact with the electrical line when inserted into the plug-in opening.
- the trigger leg is triggered by interaction with the electrical line, so that the clamping leg is released from the release position.
- the housing defines a receiving space into which the electrical cable can be inserted by inserting it into the plug opening.
- the trigger leg extends in the receiving space to interact with the electrical line.
- the electrical line can be inserted into the plug-in opening along a plug-in direction, with the trigger leg extending (approximately) transversely to the plug-in direction in the receiving space at least with one end section.
- the triggering element can, for example, be designed as an integral, elastically resilient element.
- the triggering element has a supporting end, relative to which the triggering leg is elastically adjustable by interacting with the line inserted in the plug-in opening.
- the triggering element is supported on the housing via the supporting end, for example by fastening the supporting end to an associated connecting device of the housing.
- the trigger element is thus attached to the housing via the supporting end, in that the supporting end is in operative connection with a connecting device of the housing and is held on the housing in a torque-proof manner.
- the supporting end is fixed to the connecting device of the housing in a torque-proof manner.
- the supporting end can be extended flat, which has the advantage that a contour can be easily formed on the supporting end, for example by punching, via which a reliable, for example positive, fixation on the connecting device of the housing can take place.
- the trigger leg can be adjusted elastically in the receiving space and extends in the receiving space in such a way that an electrical cable inserted into the plug-in opening strikes the trigger leg when inserted into the receiving space and thus deflects it .
- the supporting end has at least a first form-fitting element
- the connecting device of the housing comprises at least a second form-fitting element.
- the at least one first form-fitting element and the at least one second form-fitting element engage with one another in a form-fitting manner in order to fix the supporting end on the housing.
- a positive connection is thus created between the supporting end and the housing in such a way that the supporting end is held on the housing in a torque-resistant manner.
- the trigger leg can be deflected elastically towards the support leg, with the support end being fixed to the housing in such a way that a torque can be introduced into the housing via the support end and is supported on the housing.
- One of the form-fitting elements can be formed, for example, by a recess.
- the other of the form-fitting elements is then formed by a projection element, which positively fits into the recess to fix the supporting end on the housing intervenes.
- the supporting end can have a recess which engages with an associated positive-locking element in the form of a projection element on the housing.
- the positive engagement is in particular such that the supporting end cannot slide off the housing, but is held on the housing in such a way that the supporting end remains in position on the housing in the event of an elastic deflection of the trigger leg.
- the connecting terminal has an actuating element which is adjustably arranged on the housing and which can be adjusted from a non-actuated position into an actuated position in order to move the clamping leg into the release position.
- the actuating element can be actuated by a user, for example manually or using a suitable tool, and for this purpose has an actuating section which is accessible from outside the housing.
- the actuating element locks with the triggering element in the actuated position.
- the actuating element In the actuated position, the actuating element is thus held in position via the triggering element, so that the clamping leg of the spring element is also held in its release position, in which a simple attachment of an electrical line to the connection terminal is possible or a connected line in a substantially powerless position can be removed from the connection terminal.
- the actuating element can, in particular, automatically adjust itself, preferably under spring preload, back towards the non-actuated position.
- a spring preload on the actuating element can be effected, for example, via the clamping leg, which is elastically deflected in the actuated position and, after the actuating element has been released, acts spring-mechanically on the actuating element to transfer the actuating element from the actuated position towards the non-actuated position.
- the trigger leg is locked in a latching position with the actuating element located in the actuated position. From the locking position, the trigger leg can be adjusted to release the actuating element from the actuated position by interacting with the electrical line.
- the actuating element is mounted on the housing so that it can pivot about a pivot axis and has an actuating section for actuation by a user and an active section for acting on the clamping leg. While the actuation section is accessible from outside the housing, for example a user can act on the actuating section using a tool, for example a screwdriver, or alternatively manually, the active section is in operative connection with the clamping leg of the spring element.
- a tool for example a screwdriver
- the active section is in operative connection with the clamping leg of the spring element.
- the actuating element has a latching section for latching with a latching device of the triggering element in the actuated position.
- the latching section can, for example, be arranged on a side of the actuating element facing away from the actuating section (with respect to the pivot axis of the pivotable mounting of the actuating element on the housing), preferably approximately diametrically distant from the actuating section with respect to the pivot axis.
- the actuating element Via the locking section, the actuating element is locked in the actuated position with an associated locking device of the triggering element, so that the actuating element is held in the actuated position, but can be released from the actuated position in a simple, reliable manner by triggering the triggering leg when the electrical cable is plugged in can.
- the latching device of the triggering element can be formed, for example, by an opening into which the latching section of the actuating element, for example formed by a projection, engages in the actuated position of the actuating element.
- the actuating element is thus held in position in its actuated position by positive engagement of the locking section in the opening of the triggering element, the engagement being canceled by adjusting the triggering leg and the actuating element can thus be released from the actuated position in order to transfer the clamping leg into the release position.
- the opening into which the latching section of the actuating element engages in a latching manner in the actuated position can, for example, be formed on the trigger leg of the trigger element.
- the engagement can be canceled by moving the trigger leg relative to the locking section of the actuating element and thus canceling the locking connection.
- connection terminal is, in one embodiment, part of a connection arrangement of a plurality of connection terminals that are arranged next to one another along a rowing direction are.
- the rowing direction extends transversely to the plugging direction, along which an electrical cable is to be plugged into the connection terminal.
- connection terminals can rest against one another and interact with one another in such a way that the side wall of one connection terminal also provides a side wall for an adjacent, further connection terminal.
- a single connection terminal is therefore not closed to the outside, but is only closed when several connection terminals are lined up together.
- connection terminals of the arrangement can be identical. However, the connection terminals can also differ, for example, in terms of their dimensions, for example the width in the direction of arrangement and the number and/or size of the plug-in opening.
- the housing of the connection terminal can, for example, be formed by two housing parts attached to one another along the direction of arrangement, with adjacent connection terminals being able to use the housing parts together.
- the supporting end of the triggering element of the connection terminal is held in position together by the housing parts, the housing parts each having, for example, a connecting device.
- the supporting end of the trigger element can be attached, for example, to the connecting devices of the housing parts.
- the supporting end can be arranged between side walls of the housing parts that extend parallel to one another in such a way that the supporting end is fixed in a form-fitting manner between the side walls of the two housing parts and, for example, engages in a form-fitting manner with the connecting devices of the housing parts.
- the supporting end is thus held between the adjacent housing parts of adjacent connection terminals and is fixed above it with its supporting end in such a way that the trigger leg of the triggering element can be deflected elastically towards the supporting end, but the supporting end remains in position and can absorb torques.

- the positive connection between the supporting end 132 and the housing 10 is such that the supporting end 132 cannot slide out of the connecting devices 103, 103 'and in addition the supporting end 132 is supported on the housing 10 in such a way that when the trigger leg is elastically deflected 130 torques can be picked up at the supporting end 132 and derived into the housing 10 and the supporting end 132 remains in position relative to the housing 10.
- the engagement opening 107, 107' is formed on a wall section 106, 106' of the respective housing part 105, 105', which protrudes from a flat side wall of the housing part 105, 105', as can be seen from FIGS. 4A, 4B.
- the supporting end 132 of the connecting terminal 1 is accommodated between the housing parts 105, 105' of the adjacent connecting terminals 1, 1A in such a way that the supporting end 132 is positively connected to the connecting devices 103, 103' which are mirror-inverted to one another Housing parts 105, 105 'of the connection terminals 1, 1A is held.
- the housing parts 105, 105 'thus together form the housing 10 of the connecting terminal 1.
- the trigger element 13 is fixed to the connection terminal 1 by the housing 10 and is thus held in position relative to the housing 10 of the connection terminal 1 when the connection terminal 1 is mounted and ready for operation.
- the triggering leg 130 serves to cooperate with an electrical line 2 inserted into the plug-in opening 100, in particular in order to automatically connect the electrical line 2 to the connecting terminal 1 by triggering the clamping leg 120.
- the triggering element 13 has an opening 131 with which the actuating element 14 locks via a latching section 143 in the form of a projection when the actuating element 14 has been moved into an actuated position in an actuating direction B.
- the actuating element 14 engages with the locking section 143 in the opening 131 and is held in a locking manner on the trigger leg 130, so that the actuating element 14 is locked in the actuated position.
- the trigger leg 130 is bent in on itself. Between a free end 138 of the trigger leg 130 remote from the supporting end 132 and a leg section 137 of the trigger leg 130 which is aligned with the supporting end 132 and on which the opening 131 is formed, there is an intermediate section 136 which extends transversely between the free end 138 of the trigger leg 130 and the leg section 137 of the trigger leg 130 carrying the opening 131 is extended.
- the triggering element 13 can be adapted to the installation space conditions within the receiving space 101 housing 10.
- the actuating element 14 takes the clamping leg 120 of the spring element 12 with it via an active section 144 and thereby adjusts the clamping leg 120 into a release position.
- the free end of the clamping leg 120 is removed from the contact section 110 of the contact element 11 and thus releases an area within the receiving space 101 that is aligned with the plug-in opening 100 along the plug-in direction E, so that an electrical line 2 is unhindered by the clamping leg 120 the plug opening 100 can be inserted and thus connected to the connection terminal 1 in a substantially powerless manner.
- a casserole element 133 is formed by a bent section of the trigger element 13 shaped as a sheet metal element, on which the locking section 143 rests in the locked position and on which the locking section 143 rests when released from the locking accrues. Because the electrical line 2 acts on the trigger leg 130 with a lever arm that is larger than the lever arm acting on the locking section 143, the trigger leg 130 can be deflected with little force to be applied by the electrical line 2 and thus the locking when the electrical line 2 is plugged in is easy and stored reliably.
- the latching section 143 comes to lie in the latched position, in which the latching section 143 engages in the opening 131, at a contact point C on the casserole element 133, which extends to a plane P along which the support section 137 aligned with the supporting end 132 extends. is offset.
- the actuating element 14 when the actuating element 14 is locked to the triggering element 13 by engagement of the latching section 143 in the opening 131 on the leg section 137, the actuating element 14 exerts a torque on the triggering element 13 via the latching section 143, which is shown in the sectional view according to FIG is directed counterclockwise and thus in a direction that additionally reinforces the latching engagement of the latching section 143 with the opening 131.
- the locking section 143 slides into the opening 131 with elastic deflection of the trigger leg 130, and the trigger leg 130 then returns to its starting position, in which the trigger leg 130 is locked with the locking section 143 of the actuating element 14.
- the trigger leg 130 is loaded by the locking section 143 of the actuating element 14 on the casserole element 133 and due to the resulting torque in the direction of Actuating element 14 pressed so that the latching section 143 moves into complete engagement with the opening 131 on the leg section 137.
- the actuating element 14 moves out of the actuated position due to the elastic pretension on the clamping leg 120 and is reset against the actuation direction B.
- the clamping leg 120 comes into clamping contact with the electrical line 2 and thereby presses the conductor end 20 into contacting contact with the contact element 11, so that the line 2 is electrically connected to the connection terminal 1 and is also mechanically locked.
- the actuating element 14 can again be moved into the actuated position, so that the clamping leg 120 is brought out of contact with the line 2.
- the line 2 can thereby be removed from the connection terminal 1 in a substantially powerless manner.
- test openings 300 are formed on the outer housing 30, into each of which a test tool 4 with a test syringe 40 can be inserted, as shown in FIGS. 9 and 10.
- Each test opening 300 is assigned to one of the connection terminals 1, 1A of the connection arrangement 3, so that a voltage can be tapped for testing purposes via a testing tool 4 at a connection terminal 1, 1A and thus it can be checked at what potential the connection terminal 1, 1A is located.
- the contact element 11 has different legs which extend from the contacting device 111.
- a first leg forms the contact section 110, which extends flatly along a plane which is spanned by the plug-in direction E and a transverse direction Q pointing transversely to the plug-in direction E.
- a second leg forms a tapping section 112, which is oblique to the plane of the contact section 110 and is thus aligned obliquely to the plug-in direction E and also obliquely to a vertical direction V perpendicular to the plug-in direction E and to the transverse direction Q.
- the testing tool 4 can be inserted along the vertical direction V into the testing opening 300 assigned to a connecting terminal 1, 1A in order to make contact with the testing syringe 40 with the tapping section 112 of the contact element 11 of the connecting terminal 1, 1A.
- the legs each extend from the contacting device 111, which in the illustrated embodiment is formed by a contact socket with contact lamellae, between which, for example, a contact pin of a mating connector can be inserted for plug-in connection of the connection arrangement 3 with the mating connector.
- the contact section 110 points, starting from the contacting device 111, with a free end in the direction of the plug opening 100.
- the tap section 112 in contrast, extends obliquely in the housing 10 into the area of a test opening assigned to the respective connection terminal 1 300.
- the tapping section 112 With a free end, the tapping section 112 is received in engagement openings 109, 109 'on the raised wall sections 106, 106' of the housing parts 105, 105', as can be seen from Fig. 10 in conjunction with Fig. 4A, 4B, so that above the tapping section 112 is supported on the housing 10 formed by the housing parts 105, 105 '.
- the support leg 121 of the spring element 12 is received in support openings 108, 108 'of the housing parts 105, 105' and is supported on the housing 10.
- the housing 10 is made of an electrically insulating material, in particular plastic, so that the spring element 12 is not electrically contacted with the contact element 11 when the clamping leg 120 is in the release position and is therefore away from the contact section 110 of the contact element 11. Because a test tap is made on the contact element 11 via the tap section 112, a voltage can be tapped directly on the contact element 11 via the test tool 4, regardless of the position in which the clamping leg 120 of the spring element 12 is located.
- connection terminal 1 As can be seen from the separate view of the outer housing 30 of the connection arrangement 3 according to FIG a test opening 300 assigned to connection terminal 1 slides.
- the test syringe 40 is thus guided on the housing 30 and guided into the area of the tapping section 112, so that the test syringe 40 reliably contacts the end section 112 when it is inserted into the test opening 300.
- the contact element 11 can be formed as a sheet metal element, for example as a stamped and bent part, and can therefore be produced simply and inexpensively.
- the triggering element can be designed, for example, as a metal sheet metal element.
- Other configurations of the trigger element are also conceivable and possible, for example production from plastic.
