Description

Terminal for connecting an electrical cable LU502540

The invention relates to a connection terminal for connecting an electrical line according to the preamble of claim 1.

Such a connection terminal comprises a housing that has a plug-in opening into which the electrical cable can be inserted for connection to the connection terminal. A contact element for electrical contact with the electrical line is arranged on the housing. A spring element is also arranged on the housing and has a clamping leg which is designed to act on the electrical

Line to act in order to bring the electrical line into contact with the contact element when the electrical line is inserted into the plug opening. A

Actuating element can be operated by a user to adjust the clamping leg. The actuating element can be used for this purpose, for example

Tool can be adjusted from a non-actuated position to an actuated position in order to make the clamping leg easier in the actuated position, for example

To insert the electrical cable into the plug-in opening or to remove the electrical cable from the plug-in opening.

Such a connection terminal is realized by using the spring element

Spring-cage connection in which the electrical cable is in the connected position with the

Contact element is clamped under the elastic spring action of the spring element and is therefore electrically connected to the contact element.

In a connection terminal known from DE 10 2019 127 464 B3 there is a

Spring element is provided in the form of a tension spring, which has a connected electrical

Cable pulls into contact with an associated contact element through elastic spring action and thus creates a clamping connection between the electrical cable and the

Contact element produces. For this purpose, the electrical line is connected by a

Opening in the clamping leg pushed through and clamped in the connected position between the clamping leg and the contact element.

In the connection terminal of DE 10 2019 127 464 B3, a latching device is provided, via which the clamping leg is in a release position relative to the

Housing is locked. When the electrical cable is plugged in, the locking device is triggered and the locking is released, so that the clamping leg comes out of the

Release position is adjusted and thereby the electrical line is jammed with the contact element. In order to move the clamping leg into the release position, in particular LU502540 to enable the electrical cable to be attached or to detach a connected electrical cable from the connection terminal, a tool, for example a screwdriver, can be placed on the connection terminal and thereby apply a force to the connection terminal

Clamping legs can be exercised.

While in DE 10 2019 127 464 B3 the clamping leg is adjusted directly using a tool, in the 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 connected to the housing via a tension spring in the form of a compression spring

Connection terminal spring-loaded. In the one known from DE 10 2019 135 203 A1

In this case, an actuating lug is arranged on the connecting terminal on the actuating element, which in the actuated position of the actuating element is on a

Fastening section of a holding element is hooked.

The object of the present invention is to provide a connection terminal which makes it possible in a simple manner to hold the clamping leg of the spring element in a release position and when an electrical cable is inserted into one

to transfer to the clamping position.

This task is solved by an object with the features of claim 1.

Accordingly, the connection terminal has a triggering element which has a supporting end and a triggering leg which is elastically adjustable relative to the supporting end. The

Housing has a connecting device to which the supporting end is attached. The

The actuating element is designed to lock with the triggering element in the actuated position, so that the actuating element is held in the actuated position. The

The release leg is designed to release the actuating element from the actuated

Position to interact with the electrical cable when inserted into the plug opening.

At the connection terminal, the electrical cable is electrically connected to the electrical

Contact element contacted by the electrical element being inserted into the plug opening

The clamping legs act on the electrical cable and insert it in a spring-elastic manner

Direction of a contact loaded with the contact element. In order to make it easier to plug in the LU502540 electrical cable, the clamping leg of the spring element can be deflected elastically by actuating the actuating element in order to achieve the

To transfer the clamping leg into a release position in which there is a space in the area of

Plug opening is released and thus the electrical line is essentially weaker

Way inserted into the plug opening or (alternatively) a connected electrical one

Cable can be easily removed from the connection terminal. The

Actuating element can, for example, be designed in the manner of a pusher and through

User operation can be pressed into the housing while pivoting relative to the housing in order to act on the clamping leg in this way and the

Adjust the clamping leg in the direction of the release position.

The actuating element, which is pivotally mounted on the housing, locks in the actuated position with a trigger element which is supported on the housing via a supporting end. The trigger element is directly on the support end

Housing attached in that the supporting end is in operative connection with a connecting device of the housing and is held torque-tight on the housing.

In the actuated position, the actuating element is thus pushed in via the trigger element

Position held so that the clamping leg of the spring element is also in its position

Release position is held in which an electrical cable can be easily attached to the connection terminal or a connected cable can be placed in an im

Can be removed from the connection terminal in a substantially powerless manner.

The trigger element is used to lock with the actuating element in the actuated

Position. By actuating the actuating element, the clamping leg can be adjusted relative to the housing and moved into a release position, so that in particular an electrical cable can be easily inserted into the plug-in opening of the

Housing for connecting the cable to the connection terminal is possible. The

The triggering element also serves to release the actuating element from the actuated position in order to activate the actuating element automatically when the electrical element is plugged in

To release the cable into the plug-in opening from the actuated position and thus the

To transfer the clamping leg into 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. For this purpose, the triggering element has a triggering leg, which is used to

Cooperation with the electrical line when inserted into the plug opening is formed. Through interaction with the electrical line, the

Trigger arm triggered so that the actuating element locks with the LU502540

Trigger element is canceled and the actuating element is thus removed from the actuated

position is released.

After the locking has been released, the actuating element can move back in the direction of the non-actuated element, in particular automatically, preferably under spring preload

Adjust position. A spring preload on the actuating element can be effected in particular via the clamping leg, which is elastically deflected in the actuated position and, after the actuating element has been released, spring-mechanically on the actuating element to transfer the actuating element from the actuated position

Position acts in the direction of the non-actuated position.

Because the trigger leg of the trigger element is plugged in when the electrical

If the cable is deflected, the connection terminal closes automatically when the electrical cable is plugged in. The result is a simple connection process that is reliable

Contacting the electrical line with the contact element through the clamping effect of the

clamping leg.

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.

In one embodiment, the housing defines a receiving space into which the electrical line can be inserted by inserting it into the plug-in opening. The

Trigger leg extends in the receiving space to interact with the electrical line. In particular, the electrical line can be along a

Plugging direction can be inserted into the plugging opening, with the trigger leg extending transversely to the plugging direction in the receiving space. The trigger leg can be deflected elastically in relation to the support leg of the trigger element, so that the trigger leg is adjusted elastically when interacting with the electrical line.

While the supporting end is supported in a torque-resistant manner relative to the housing, the

The trigger leg can be adjusted elastically in the receiving space and extends in the receiving space in such a way that an electrical plug inserted into the plug-in opening

The cable hits the trigger leg when it is inserted into the receiving space and the LU502540 thus deflects it.

In one embodiment, the trigger leg is locked in a latching position with the actuating element located in the 5 actuated position. From the locking position, the trigger leg can be used to release the actuating element from the actuated position

Position can be adjusted by interacting with the electrical cable. The

The actuating element is locked in the actuated position via the

Trigger leg. By deflecting the trigger leg out of the locking position, the

Latching can be canceled so that the actuating element is removed from the actuated

Position is released and thus the clamping leg of the spring element from the

Release position can be adjusted in the direction of a clamping position.

In one embodiment, the spring element is designed as a tension spring. In this case, the clamping leg of the spring element is designed to pass the electrical line

To pull spring force into contact with the contact element. In this case, for example, an opening can be formed on the clamping leg through which the electrical line can be connected

Insertion into the plug opening of the housing can be passed through in order to

Release the clamping leg from the release position to pull the electrical cable into clamping contact with the contact element.

Alternatively, the spring element can be designed as a compression spring. In this case the

Clamping legs designed to press the electrical line into contact with the contact element by spring force. When inserted into the plug opening, the electrical cable enters a space between the clamping leg and the

Contact element, whereby after the clamping leg has been released from the release position

Clamping leg acts on the electrical line and puts it in contact with the

Contact element presses.

In one embodiment, the clamping leg is elastically adjustable relative to the housing by actuating the actuating element into a release position and is in the

Release position held relative to the housing by the actuating element locked in the actuated position. The clamping leg is therefore in the release position

The housing is locked so that the clamping leg remains in the release position after the actuating element has been actuated.

The spring element can, for example, have a support leg over which the LU502540

Spring element is supported on the housing and held in position on the housing.

The clamping leg can be elastically deflected relative to the support leg, whereby in the

Release position of the clamping legs is deflected so 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.

In one embodiment, the supporting end has at least a first positive-locking element, while the connecting device of the housing has at least a second

Form-fitting element includes. The at least one first form-fitting element and the at least one second form-fitting element stand on the support end for fixing

Housing engages with each other in a form-fitting manner. It therefore becomes a form-fitting one

Connection between the supporting end and the housing created in such a way that

Supporting end is held torque-tight on the housing. The trigger leg can be deflected elastically towards the support leg, with the support end attached to it

Housing is determined that a torque can be introduced into the housing via the supporting 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 engages in a form-fitting manner in the recess to fix the supporting end on the housing. For example, the supporting end can have a recess which is connected to an associated positive-locking element in the form of a projection element on the housing

intervention stands. 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 when the trigger leg is elastically deflected, the supporting end is in position on the

Housing remains.

In one embodiment, 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 effective section for acting on the clamping leg. During the

The actuating section is accessible from outside the housing, for example by a user using a tool, for example a screwdriver, or alternatively can act on the actuating section manually, the active section is connected to the

Clamping leg of the spring element in \active connection. By adjusting the

The actuating element thus applies an adjusting force to the active section

Clamping leg is exerted, so that in particular when the actuating element is adjusted from the non-actuated position to the actuated position, the clamping leg LU502540 is taken along and thus moved in the direction of the release position.

In one embodiment, the actuating element has a pass-through opening through which the spring element reaches. The spring element can in particular be formed by a curved sheet metal spring, in which the clamping leg runs along a

Adjustment plane can be deflected relative to the support leg. The spring element extends through the access opening of the actuating element, to

Example around the pivot axis of the actuating element, so that the

Spring element over the support leg on the housing on a first side of the

Actuating element is supported and the clamping leg protrudes from the actuating element on a second side facing away and when adjusting the

Actuating element is adjusted together with the actuating element. This results in a space-efficient arrangement of the actuating element and the spring element, with effective introduction of force into the spring element when transferring the actuating element from the non-actuated position to the actuated position and also from the spring element into the actuating element when returning the actuating element from the actuated one

Position due to the spring preload of the spring element.

In one embodiment, the actuating element has a latching section for latching with a latching device of the triggering element in the actuated position. The

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. On the

In the latching section, the actuating element is locked in the actuated position with an associated latching device of the triggering element, so that the

Actuating element is held in the actuated position by triggering the

Trigger leg but when plugging in the electrical cable in a simpler, more reliable way

Way can be released from the actuated position.

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, whereby

Adjusting the trigger leg cancels the engagement and the actuating element is thus removed from the actuated position for transferring the clamping leg into the LU502540

Release position can be solved.

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. By adjusting the trigger leg, the engagement can be canceled by moving the trigger leg relative to the locking section of the

Actuating element moves and thus the latching connection is canceled.

The connection terminal is, in one embodiment, part of a connection arrangement of a plurality of connection terminals which are arranged next to one another along a rowing direction. The rowing direction extends transversely to the plugging direction, along which an electrical cable is to be plugged into the connection terminal.

The connection terminals can rest against one another and interact with one another in such a way that the side wall of a connection terminal also has a

Side wall provides for an adjacent, additional 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.

The connection terminals of the arrangement can be identical. The connection terminals can also differ, for example, in terms of their dimensions, for example

Width in the direction of arrangement and the number and/or size of the plug-in openings differ.

The housing of the connection terminal can, for example, be formed by two along the

Housing parts attached to one another in the direction of arrangement can be formed, with adjacent ones

Connection terminals can share the housing parts. Advantageously, it can be provided that the supporting end of the trigger element of the connection terminal is held in position together by the housing parts, the housing parts being

Example each have a connection device. For this purpose, the supporting end of the

Trigger element can be attached, for example, to the connecting devices of the housing parts. For example, 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, in a form-fitting manner with the connecting devices of the housing parts

intervention stands. The supporting end is therefore between the ones lined up next to each other

Housing parts of adjacent connection terminals are held and above them with its LU502540

Supporting end set so that the trigger leg of the trigger element is elastic to the

Supporting end can be deflected, but the supporting end remains in position and

Can absorb torques.

The idea underlying the invention will be explained in more detail below using the exemplary embodiments shown in the figures. Show it:

1 and 2 show an exemplary embodiment of a connection arrangement 3, which has a

A plurality of connection terminals 1, 1A, which are enclosed together in an outer housing 30. The connection terminals 1, 1A are lined up along a rowing direction A and enclosed together in the outer housing 30, with each connection terminal 1, 1A being assigned a plug-in opening 100 on a housing 10, into which an electrical line 2 with a (stripped) conductor end 20 along a LU502540

Plugging direction E can be plugged in to connect the electrical cable 2 to the

Connect terminal 1, 1A.

Fig. 3 shows a sectional view along the line AA according to Fig. 2

Embodiment of a connection terminal 1, which has a housing 10 with a plug opening 100 formed therein for inserting an electrical line 2 along a

Plugging direction E.

The housing 10 defines a receiving space 101 into which the electrical line 2 with a stripped conductor end 20 is inserted when it is inserted into the plug-in opening 100 along the plug-in direction E. The is in a connected position

Line 2 with the stripped conductor end 20 within the receiving space 101 and is electrically connected via a clamping leg 120 of a spring element 12 with a

Contact element 11 contacted in the form of a current bar, so that the electrical line 2 is electrically connected to the connection terminal 1.

The spring element 12 has a support leg 121 which is on a wall of the

Housing 10 is supported, so that the spring element 12 is attached to the housing 10 and fixed to the housing 10. The clamping leg 120 can be deflected elastically to the support leg 121, in particular in such a way that the clamping leg 120 acts in a clamping position on an electrical line 2 connected to the connecting terminal 1 and brings it into contact with the electrical line 2 under elastic prestress

Contact element 11 presses and thus the line 2 is electrically connected via its conductor end 20

Contact element 11 contacted.

The contact element 11 has a contact section 110, which extends flatly in the housing 10 and against which the electrical line 2 with the conductor end 20 passes

Spring preload of the clamping leg 120 is pressed when the electrical line 2 is connected to the connecting terminal 1. The contact section 110 is connected to a contacting device 111 arranged in a plug connector section 15, via which the connecting terminal 1 is connected to an associated electrical

Mating connector can be connected.

In the exemplary embodiment shown, the housing 10 of the connection terminal 1 is formed by housing parts 105, 105 'shown in FIGS. 4A and 4B. The neighboring ones

Terminals 1, 1A use the housing parts 105, 105' together. The

Housing 10 of a connection terminal 1 is thus formed by a housing part 105 and an adjacent housing part 105 'of an adjacent connection terminal 1A.

As can be seen from FIGS. 4A, 4B, the housing parts 105, 105' of the connecting terminals 1, 1A arranged in a row are placed together and together in the

Outer housing 30 of the connection arrangement 3 is enclosed, as can be seen from FIG.

On the housing 10 of the connection terminal 1 there is an actuating element 14 via a

Pivot axis 140 pivotally mounted. The actuating element 14 can be around

Pivot axis 140 can be pivoted relative to the housing 10, with a

Actuating section 141 is accessible via an actuating opening 102 from outside the housing 10 and thus by a user, for example using a

Tool, can be operated.

In the exemplary embodiment shown, the pivot axis 140 is formed on the housing part 105, into which an axle stub 140° of the housing part 105 'engages and thus the

Pivot bearing of the actuating element 14 on the housing 10 is completed, as can be seen from FIGS. 4A, 4B.

The actuating element 14 is in contact with the clamping leg 120 of the spring element 12

Active connection. For this purpose, the spring element 12 passes through a passage opening 142 within the actuating element 14 in such a way that the spring element 12 reaches around the pivot axis 140 with a curved intermediate section 122, as shown

Fig. 3 can be seen. The support leg 121 projects out of the opening 142 on a first side and is supported on the housing 10. The clamping leg 120, on the other hand, protrudes from the actuating element 14 on a remote, second side and is so extended within the receiving space 101 in the area of the plug-in opening 100 that the spring element 12 extends via the clamping leg 120 onto an electrical line 2 inserted into the plug-in opening 100 for contacting with the contact element 11 and can also act for mechanical locking.

The connection terminal 1 has a trigger element 13, which is attached to the housing 10 via a supporting end 132 and is thereby supported in a torque-resistant manner relative to the housing 10. A trigger leg 130 extends from the supporting end 132 and is in the

Substantially transverse to the plug-in direction E projects into the receiving space 101 and thus extends in an area aligned with the plug-in opening 100.

As can be seen from the separate view of the trigger element 13 according to FIGS. 5A-5C

Detailed views of the housing part 105 according to FIGS. 6A, 6B and 7A, 7B and the

8, the supporting end 132 of the trigger element 13 is in a form-fitting manner with connecting devices 103, 103 'of the housing 10

Connecting terminal 1 forming housing parts 105, 105 'connected. The supporting end 132 of the triggering element 13, which is formed by a band-shaped spring element, has recesses 134, 135 on its opposite lateral edges, which in the mounted position of the triggering element 13 with projection elements 104, 104 'on the

Connecting devices 103, 103 'are engaged.

The connecting devices 103, 103° are each formed by an engagement opening 107, 107°, into which the supporting end 132 engages, so that the supporting end 132 is received in a form-fitting manner on the housing 10. The positive connection between the supporting end 132 and the housing 10 is such that the supporting end 132 does not come out of the

Connecting devices 103, 103 'can slide out and in addition the supporting end 132 is supported on the housing 10 in such a way that when it is elastically deflected

Trigger leg 130 torques are recorded at the support end 132 and into that

Housing 10 can be derived and the supporting end 132 remains in position relative to the housing 10.

The engagement opening 107, 107 'is on a wall section 106, 106 ° of the respective

Housing part 105, 105 'shaped, which protrudes from a flat side wall of the housing part 105, 105 °, as can be seen from Fig. 4A, 4B.

As can be seen from the sectional view according to FIG. 8, the supporting end 132 is the

Connection terminal 1 between the housing parts 105, 105° of the adjacent

Terminals 1, 1A recorded in such a way that the supporting end 132 is held in a form-fitting manner on the mirror-inverted connecting devices 103, 103 'of the housing parts 105, 105' of the connection terminals 1, 1A. 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 trigger leg 130 serves to interact with an electrical line 2 inserted into the plug-in opening 100 LU502540, in particular to automatically connect the electrical line 2 to the connection terminal 1 by triggering the clamping leg 120.

The trigger 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 transferred into an actuated position in an actuating direction B. In the actuated position, the actuating element 14 engages with the

Locking section 143 into 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.

In the exemplary embodiment shown, the trigger leg 130 is bent in on itself.

Between a free end 138 remote from the supporting end 132

Trigger leg 130 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

Intermediate section 136 extends transversely between the free end 138 of the

Trigger leg 130 and the leg section 137 carrying the opening 131

Trigger leg 130 extends. By appropriately shaping the triggering element 13, the triggering element 13 can adapt to the installation space conditions within the

Recording room 101 housing 10 can be adjusted.

If the actuating element 14 is actuated in the actuating direction B and thereby around the

Pivot axis 140 is pivoted relative to the housing 10, this takes

Actuating element 14 the clamping leg 120 of the via an active section 144

Spring element 12 and thereby adjusts the clamping leg 120 into one

Release position. In the release position, the clamping leg 120 is free

End removed from the contact section 110 of the contact element 11 and thus provides an area within the which is aligned with the plug-in opening 100 along the plug-in direction E

Receiving space 101 is free, so that an electrical line 2 is unhindered by the

Clamping leg 120 is inserted into the plug-in opening 100 and thus in one

Can be connected to the connection terminal 1 in a substantially powerless manner.

If an electrical cable 2 with a stripped conductor end 20 is inserted into the plug-in opening 100 and thereby inserted into the receiving space 101 in the plug-in direction E, while the actuating element 14 is in the actuated position and thus the

If the clamping leg 120 is in the release position, the line 2 comes into contact with the tripping leg 130 of the tripping element 13 and deflects it elastically relative to the supporting end 132 and thus to the housing 10. This makes the LU502540

Trigger leg 130 in the plug-in direction E relative to the locking section 143 of the

Actuating element 14 adjusted so that the locking section 143 is disengaged from the

Opening 131 arrives and thus the actuating element 14 is released from the actuated position.

On a side of the opening 131 facing the free end 138 of the trigger leg 130, 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 is locked

Position is applied and on which the locking section 143 runs when released from the locking.

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.

As can be seen from FIG. The

Locking section 143 comes to rest in the locked position, in which the locking section 143 engages in the opening 131, at a contact point C on the casserole element 133, which leads to a plane P along which the plane P is aligned with the supporting end 132

Support section 137 extends, is offset. As a result, when the actuating element 14 is locked to the triggering element 13 by engagement of the locking section 143 in the opening 131 on the leg section 137, the actuating element 14 exercises over the

Locking section 143 exerts a torque on the trigger element 13, which is in the

Sectional view according to FIG. 3 is directed counterclockwise and thus in a

Direction that additionally reinforces the latching engagement of the latching section 143 with the opening 131.

When the locking is established, the locking section 143 slides into the opening 131 with elastic deflection of the release leg 130, and the release leg 130 then returns to its starting position, in which the release leg 130 with the

Locking section 143 of the actuating element 14 is locked. 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 locking section 143 is in complete LUS02540

Engagement with the opening 131 on the leg section 137 moves.

This happens after the locking is released when an electrical cable 2 is plugged in

Actuating element 14 moves out of the actuated position due to the elastic preload 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.

Because the actuating element 14 is moved out of the actuated position after the latching is released, a user can safely and reliably recognize that the

Terminal 1 has tripped and the electrical line 2 is therefore connected to the

Terminal 1 is connected. The risk of incorrect operation is therefore reduced.

If the electrical line 2 is to be released from the connected position and removed from the

If the connecting terminal 1 is removed again, 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 in one

Can be removed from the connection terminal 1 in a substantially powerless manner.

The idea underlying the invention is not limited to that described above

Exemplary embodiment is limited, but can also be implemented in another way.

The triggering element can be designed, for example, as a metal sheet element.

Other configurations of the trigger element are also conceivable and possible, for example production from plastic.
