Description

Terminal for connecting an electrical cable LU502538

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 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 is adjustable to the housing

Has clamping leg, which is designed to be in a clamping position on the electrical

Line for contacting with the contact section and in one

Release position is away from the contact section compared to the clamping position.

Here, 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 line can pass through

Plug it into the plug-in opening and connect it to the connection terminal. A

The 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.

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 pushed through in the clamping leg 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 LU502538

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 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

Each via a tension spring in the form of a compression spring relative to the housing

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.

With a connection terminal of the type described, it may be desirable to have one

A test tap must be provided in order to tap a voltage at the connection terminal by placing a test tool on the connection terminal. With a conventional one

Such a test tap is often designed in such a way that:

Test tool with a test syringe with the one that forms the clamping leg

Spring element can be brought into contact in order to reduce the tension on the

Check connection terminal.

It is desirable to provide a 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

If the connection terminal is delivered in this state by a manufacturer, for example, the clamping leg has no contact with the contact element, so that on the

Spring element under certain circumstances (particularly when the spring element is supported on the housing separately from the contact element) no voltage can be tapped.

In a connection terminal known from DE 10 2020 104 138 B4, there is one

Housing has a test opening formed 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 that makes it possible to easily use a testing tool

Tap the voltage at the connection terminal for testing purposes.

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

Accordingly, 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 one of the

Contacting device extended, second leg, which forms a tapping section for electrical contact with a testing tool.

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-in 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 electrical cable, 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 is inserted into the plug opening in a substantially powerless manner or a connected electrical cable is easily removed from the

Connection terminal can be removed.

Once the clamping leg has been moved into the release position, it will

Clamping leg 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. For example, the clamping leg can lock with the trigger element in the release position. Alternatively, an actuating element can be connected to the trigger element or with a

Lock the locking device on the housing. In each case, the clamping leg is held in position relative to the housing (directly or indirectly via the actuating element) in the release position, so that a user can connect an electrical cable more easily, in the LU502538

Insert it into the plug-in opening in a substantially powerless manner and thus attach it to the

Connecting terminal can be connected.

The trigger element is used to release the clamping leg from the release position in order to automatically release the clamping leg when the electrical cable is inserted

To release the release position and thus to transfer it into a clamping position in which the electrical cable inserted into the plug opening is connected to the contact element

Connection terminal is electrically contacted. Because the trigger element is at

When the electrical cable is inserted, the connecting terminal closes automatically when the electrical cable is inserted. It turns out a simple one

Connection process, with reliable contact between the cable and the contact element.

Such a connection terminal in which the clamping leg of the spring element is in the

Release position is held in position relative to the housing and which has a

Triggering element can be triggered automatically when an electrical cable is plugged in, can be delivered by a manufacturer, for example, with the clamping leg in the release position. In order to have one with such a connection terminal

To provide a test tap that can tap a voltage at the

Connection terminal allows for testing purposes is at the connection terminal on the

Contact element formed a tap section that allows electrical contact with a

Test tool enables and thus allows a voltage to be tapped on the contact element 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.

Because the tapping section with which the test tool can be brought into contact is formed on the contact element, 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 clamping leg a voltage can be picked up at the connecting terminal LU502538 if the spring element is independent of the contact element on the

Housing is supported and therefore not electrically connected to the contact element. 5 Because the contact section for contacting with the electrical line and the

Tap section for contacting with the test tool are formed on different legs of the contact element, the test tap can be provided on the connection terminal where a test tool is attached to the in a space-saving manner

Connection terminal can be attached. About the first leg, which is the

If the contact section forms, a connected electrical line contacts it

Contact element. A testing tool can be used over the second leg

Contact element can be contacted in order to tap a voltage for testing purposes.

There is one between the first leg and the second leg

Contacting device is formed, via which the connection terminal is connected, for example, to an associated electrical assembly, for example a

Mating connector, can be connected.

In one embodiment, 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

The contact section is therefore designed to be flat and is aligned parallel to the plug-in direction in which an electrical cable can be plugged into the connection terminal. At

When the electrical line is inserted, it acts on the trigger element and thus releases the clamping leg from the release position, so that the clamping leg acts on the electrical line in a clamping manner and brings it into contact with the contact section.

In one embodiment, the tapping section extends obliquely to the insertion direction. The

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. Preferably the extends

The tapping section is oblique to the vertical direction. The vertical direction can, for example, point perpendicular to the plugging direction in which an electrical line is inserted

Plug-in opening of the housing can be inserted for connection to the connection terminal LU502538, so that the test section is aligned both at an angle to the vertical direction and at an angle to the plug-in direction.

In one embodiment, the tapping section engages with one of the

Contacting device end remote into an engagement opening on the housing and is supported on the housing. 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 into it

Housing can be derived.

In one embodiment, the contact section has one of the

Contacting device end remote in the direction of the plug opening. Both that

The tapping section and the contact section therefore, in one embodiment, have a free end extending from the contacting device.

For example, the contact element can be a sheet metal element, for example in the form of a

Be designed as a stamped and bent part, in which the contact section

Contacting device and the tapping section are formed by sections of the contact element that are bent towards one another.

In one embodiment, the contacting device is designed by a contact socket for plug-in connection to the associated electrical assembly. Such a contact socket, for example in the form of a so-called contact tulip, can be used

Example, have contact lamellas, via which the contacting device can be connected to an associated electrical assembly in the form of a mating connector. A can be placed between the contact lamellae of the contact socket

Contact element of the mating connector can be inserted in order to establish an electrical connection between a connector which is part of the connector

Connecting terminal is to be made and the mating connector.

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 LU502538 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-in 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.

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 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.

The support leg can, for example, engage in a support opening on the housing and is supported on the housing via 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.

In one embodiment, the triggering element has a triggering leg which

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

Trigger leg triggered 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. In particular, the electrical line can be along a

Insertion direction can be inserted into the insertion opening, with the trigger leg being at least with one end section (approximately) transverse to the insertion direction in the

Recording room extends.

The trigger element can, for example, be an integral, elastically resilient LU502538

Element can be designed.

In one embodiment, the trigger element has a supporting end relative to which the

Trigger leg by interacting with the one inserted into the plug-in opening

Line is elastically adjustable. The trigger element is on the support end

Housing supported, for example by the supporting end on an assigned

Connecting device of the housing is attached. The trigger element is thus attached to the housing via the supporting end by connecting the supporting end with a

The connecting device of the housing is in an active connection and is held torque-tight on the housing.

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. While the supporting end is supported in a torque-resistant manner relative to the housing, the trigger leg can be adjusted elastically in the receiving space and thereby extends into it

Receiving space that has an electrical cable inserted into the plug-in opening

Insertion into the receiving space strikes the trigger leg and thus deflects it.

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 a positive locking element assigned to LU502538 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 connecting terminal has an actuating element that is adjustable on the housing and can be adjusted from a non-actuated position to an actuated position in order to move the clamping leg into the release position. The actuating element can be operated by a user, for example manually or with a suitable tool, and has a

Actuating section that is accessible from outside the housing.

In one embodiment, the actuating element locks with the in the actuated position

Trigger element. In the actuated position, the actuating element is thus over the

Trigger element held in position so that the clamping leg of the

Spring element is held in its release position, in which a simple attachment of an electrical cable to the connection terminal is possible or a connected one

Line can be removed from the connection terminal in a substantially powerless manner. After the locking has been released, 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 in the actuated

Position is deflected elastically and after release of the actuating element acts spring-mechanically on the actuating element to transfer the actuating element from the actuated position towards the non-actuated position.

In one embodiment, 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 used to release the actuating element from the actuated position

Position can be adjusted by interacting with the electrical cable.

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 LU502538 to 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 legs are exerted, so that in particular when the actuating element is adjusted from the non-actuated position to the actuated position, the clamping legs are taken along and thus moved in the direction of the release position.

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

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

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 baying direction extends transversely to the plugging direction, along which a LU502538 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 opening 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 his

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.

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 LU502538, into which an electrical line 2 with a (stripped) conductor end 20 along one

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 by the support leg 121 in a support opening 108 on one

Housing wall 106 engages, 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 connection 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 illustrated embodiment, the housing 10 of the connecting terminal 1 LU502538 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 illustrated embodiment, 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 extends within the receiving space 101 in the area of the plug-in opening 100 in such a way 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, which is shown in LU502538, extends from the support end 132

Substantially transverse to the insertion direction E protrudes into the receiving space 101 and thus extends in an area aligned with the insertion 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 triggering leg 130 serves to interact with an electrical line 2 inserted into the plug-in opening 100, in particular to automatically connect the electrical line 2 to the connecting 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 is a

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 via an active section 144 the clamping leg 120 of the

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 will make the

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 release leg 130 is loaded on the casserole element 133 by the locking section 143 of the actuating element 14 and due to the resulting torque in the direction of the

Actuating element 14 pressed so that the locking section 143 is in complete LUS02538

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.

In the connection arrangement according to FIGS. 1 and 2 there are 30 on the outer housing

Test openings 300 are formed, 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

Terminal 1, 1A is located.

As can be seen from the separate views according to FIGS. 11A, 11B, this has

Contact element 11 different legs that differ from the

Contacting device 111 extend. A first leg forms the

Contact section 110, which extends flatly along a plane through the

Plugging direction E and a transverse direction Q pointing transversely to the plugging direction E. In contrast, a second leg forms a tapping section 112, which is placed obliquely to the plane of the contact section 110 and thus obliquely to the plugging direction E LU502538 and also obliquely to a perpendicular to the plugging direction E and to the transverse direction Q

Vertical direction V is aligned.

In the exemplary embodiment shown, the testing tool 4 can be along the

Vertical direction V into the test opening 300 assigned to a connection terminal 1, 1A in order to use the test syringe 40 with the tap section 112 of the

Contact element 11 of the connection terminal 1, 1A to contact.

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.

3 and 10, 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 one of the respective connection terminals 1 Test opening 300.

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 '.

In the illustrated embodiment of the connection terminal 1, 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

Spring element 12, when the clamping leg 120 is in the release position and is therefore away from the contact section 110 of the contact element 11, is not electrically contacted with the contact element 11. Because via the tap section 112 but a

Test tap on the contact element 11 can be done via the testing tool 4

Voltage can be picked up directly on the contact element 11, regardless of the position in which the clamping leg 120 of the spring element 12 is located.

As can be seen from the separate view of the outer housing 30 of the connection arrangement 3 LU502538 according to FIG the one

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 with the when inserted into the test opening 300

Final section 112 contacted.

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 idea underlying the invention is not limited to that described above

Embodiment limited, but can also be implemented in another way.

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.
