Description

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

Such a 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 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 in order to bring the electrical line into contact with the contact element when the electrical line is inserted into the plug-in opening. An actuating element can be actuated by a user to adjust the clamping leg. For this purpose, the actuating element can be adjusted from a non-actuated position to an actuated position, for example using a tool, in order to close the clamping leg in the actuated position, for example to make it easier to insert the electrical cable into the plug-in opening or to remove the electrical cable from the plug-in opening adjust.

By using the spring element, such a 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.

At one of the DE 10 2019 127 464 B3 In the known connection terminal, 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. For this purpose, 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.

At the connection terminal DE 10 2019 127 464 B3 A locking device is provided, via which the clamping leg is locked in a release position relative to the housing. When the electrical cable is inserted, the latching device is triggered and the latching is thus released, so that the clamping leg is moved out of the release position and the electrical cable is thereby jammed with the contact element. In order to move the clamping leg into the release position, in particular to enable the electrical line to be attached or to detach a connected electrical line from the connection terminal, a tool, for example a screwdriver, can be placed on the connection terminal and thereby exert a force on the clamping leg become.

While at the DE 10 2019 127 464 B3 Adjusting the clamping leg directly using a tool is possible DE 10 2019 135 203 A1 and the DE 10 2020 104 140 A1 Known connection terminals each have an actuating element in the form of a so-called pusher, which can be pressed into the housing of the connection 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. At the from the DE 10 2019 135 203 A1 Known connection terminal, 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.

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 to move it into a clamping position when an electrical cable is inserted.

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

Accordingly, the connection terminal has a triggering element which has a triggering leg, a locking leg and a support section. The support section is supported relative to the housing, and the trigger leg and the locking leg are elastically adjustable in relation to the support section. The actuating element is locked in the actuated position with the locking leg, so that the actuating element is held in position relative to the housing in the actuated position, the locking leg being adjustable relative to the housing by the interaction of the trigger leg with the electrical line when inserted into the plug-in opening to release the actuator from the actuated position.

In the connection terminal, the electrical line is electrically contacted with the electrical contact element in that the clamping leg acts on the electrical line when the electrical line is inserted into the plug-in opening and this is resiliently loaded in the direction of contact 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 by actuating the actuating element in order to move the clamping leg into a release position in which a space inside the housing 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 (alternatively) a connected electrical cable can be easily removed from the connection terminal. The actuating element can, for example, be designed in the manner of a pusher and pressed into the housing by user operation in order to act on the clamping leg and to adjust the clamping leg in the direction of the release position.

The actuating element, which is adjustably arranged on the housing, is locked in the actuated position relative to the housing in that the actuating element is in operative connection with the locking leg of the triggering element. In the actuated position, the actuating element is thus held in position relative to the housing, 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 can be removed from the connection terminal in a forceless manner.

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 a simple insertion of an electrical cable into the plug-in opening of the housing for connecting the cable to the connection terminal is possible. The triggering element, which is arranged adjustably to the housing, serves to lock with the actuating element in the actuated position, so that the actuating element is held in position relative to the housing in the actuated position via the triggering element, namely the locking leg of the triggering element. The triggering element also serves to trigger the actuating element from the actuated position in order to automatically release the actuating element from the actuated position when the electrical cable is inserted into the plug-in opening and thus to transfer the clamping leg into a clamping position in which the electrical cable inserted into the plug-in opening is also included the contact element of the connection terminal is electrically contacted. For this purpose, the triggering element has a triggering leg which is designed to interact with the electrical line when inserted into the plug-in opening. Through interaction of the electrical line with the trigger leg, the trigger leg is adjusted and the locking leg connected to the trigger leg is deflected, so that the connection between the locking leg of the trigger element and the actuating element is canceled and the actuating element is thus released from the actuated position.

The triggering element is supported relative to the housing via the support section, so that the triggering element is connected via the support section to the housing or to a part that is stationary in relation to the housing, for example the contact element. The trigger leg and the locking leg are elastically adjustable to the support section. If the trigger leg is adjusted by interacting with an inserted electrical line, the locking leg is also moved and thus the locking of the locking leg with the actuating element is released, so that the actuating element is released from the actuated position.

Due to the elastic support via the support section, the trigger element is held in a starting position when no electrical cable is inserted into the plug-in opening of the housing. In the starting position, the actuating element can be locked with the locking leg of the triggering element. The triggering element is also in the starting position (or a position that only slightly deviates from the starting position) when the actuating element is locked with the locking leg in the actuated position. Through the interaction of an electrical line with the trigger leg, the trigger element is deflected from the starting position by moving the trigger leg and the locking leg together with the trigger leg. If the electrical line is removed again, the trigger element returns to its starting position due to the elastic support via the support section, in which the actuating element can be locked with the locking leg.

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 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. One However, preload can also be provided via an additional preload element, for example an additional spring.

Because the trigger element is adjusted to the housing when the electrical cable is inserted and the locking leg is thereby deflected, the connecting terminal closes automatically when the electrical cable is inserted. This results in a simple connection process, with reliable contact of the electrical line with the contact element through the clamping effect of the clamping leg.

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 inserted into the plug-in opening along a plug-in direction, with the trigger leg extending in the receiving space transversely to the plug-in direction in a starting position. The locking leg is adjustable to the housing via the trigger leg, so that when interacting with the electrical line, the trigger leg is moved out of the starting position and the locking leg is thereby adjusted to cancel the locking with the actuating element.

The trigger leg can, for example, define a lever arm that is larger than the lever arm of the locking leg. This enables an electrical line to act on the trigger leg with a comparatively small force in order to pivot it out of the starting 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 pull the electrical line into contact with the contact element by spring force. In this case, an opening can be formed on the clamping leg, for example, through which the electrical line can be passed when inserted into the plug-in opening of the housing in order to pull the electrical line into clamping contact with the contact element after the clamping leg has been released from the release position.

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

In one embodiment, the clamping leg is elastically adjustable relative to the housing by actuating the actuating element into a release position and is held in the release position relative to the housing by the actuating element which is locked in the actuated position. The clamping leg is thus locked in the release position relative to the housing, so that the clamping leg remains in the release position after the actuation element has been actuated.

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.

In one embodiment, the actuating element is mounted on the housing in a linearly displaceable manner and has an actuating section for actuation by a user and an active section for acting on the clamping leg. While 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 in operative connection with the clamping leg of the spring element. By adjusting the actuating element, an adjusting force is exerted on the clamping leg via the active section, so that, in particular when the actuating element is adjusted from the non-actuated position to the actuated position, the clamping leg is 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 the latching leg of the triggering element in the actuated position. The latching section can, for example, be formed as a rigid projection on a body of the actuating element and, in the actuated position of the actuating element, engages with the latching leg, for example an opening on the latching leg, so that the actuating element is latched to the latching leg. In the actuated position, the actuating element is thus held in position relative to the housing, via the actuating element ment the clamping leg is also held in its release position.

In one embodiment, the actuating element has a first stop element which, in the actuated position, rests against a second stop element which is stationary in relation to the housing and thus defines the position of the actuating element relative to the housing in the actuated position. In particular, the actuating element can be adjusted in the actuating direction to the housing until the stop element of the actuating element comes into contact with the stop element on the side of the housing and thus cannot be moved further in the actuating direction. The actuating element thus assumes a defined position relative to the housing in the actuated position and is thereby locked relative to the housing via the locking leg of the triggering element.

In one embodiment, the second stop element is formed on the contact element. The actuating element thus strikes the contact element in the actuated position and assumes a defined position relative to the housing.

The trigger element is supported relative to the housing via the support section. The support section can be held torque-resistant relative to the housing and thus fasten the trigger element to the housing. The triggering leg can be deflected together with the locking leg elastically relative to the support section in order to cancel the locking of the actuating element with the locking leg, with the triggering element returning to its starting position due to the elastic support via the support section when an electrical line is removed from the connection terminal and therefore no longer acts on the trigger element.

In one embodiment, the support section is supported on the contact element. The support section is thus connected to the contact element, which is fixed in place on the housing. For example, the support section can encompass an edge section of the contact element and thereby be fixed to the edge section of the contact element in a torque-proof manner. For this purpose, the support section can be designed, for example, as a bent tab which surrounds the edge section of the contact element and thus secures the trigger element to the contact element in a torque-proof manner.

In one embodiment, the triggering element is formed by an elastically resilient element, for example a leg spring. The trigger element is thus formed integrally and in one piece from an elastically resilient material, for example spring steel. In particular, the support section, the locking leg and the trigger leg are integrally formed by a single, one-piece element, for example as a metal stamped and bent part.

1A , 1B until 4 show an exemplary embodiment of a connection terminal 1, which forms a housing 10 with a plug-in opening 100 formed therein for plugging in an electrical line 2 along a plug-in 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. In a connected In this position, the line 2 with the stripped conductor end 20 is located within the receiving space 101 and is electrically contacted via a clamping leg 120 of a spring element 12 with a contact element 11 in the form of a current bar, so that the electrical line 2 is electrically connected to the connection terminal 1.

This in 5A-5C Spring element 12 shown in separate views has a support leg 121, which in the illustrated embodiment is supported on a surface section 112 of the contact element 11 that is bent to form a wall 113, so that the spring element 12 is attached to the housing 10 above and fixed to the housing 10. The clamping leg 120 can be deflected elastically relative to the support leg 121, in particular in such a way that the clamping leg 120 is in an in 4 shown clamping position acts clampingly on an electrical line 2 connected to the connection terminal 1 and presses it under elastic prestress into contact with a surface section 110 of the contact element 11 and thus electrically contacts the line 2 with the contact element 11 via its conductor end 20.

In the exemplary embodiment shown, an actuating element 14 is mounted on the housing 10 so as to be displaceable along an actuation direction B. The actuating element 14 is slidably received in an actuating opening 102 of the housing 10 and can be displaced along the actuating direction B in a linearly guided manner relative to the housing 10 in order to thereby act on the clamping leg 120 of the spring element 12 and to close it between the clamping position and a release position adjust.

This in 6A-6E Actuating element 14 shown in separate views has an actuating section 141, which is accessible from outside the housing 10 via the actuating opening 102 and can therefore be actuated by a user, for example using a tool. The actuation section 141 is accommodated in the actuation opening 102 and is slidably guided in the actuation opening 102.

The actuating element 14 is in operative connection with the clamping leg 120 of the spring element 12. For this purpose, the actuating element 14 acts with an active section 144 on the clamping leg 120 in order to adjust it with elastic deflection to the support leg 121 in the receiving space 101 of the housing 10. In an in 2A , 2 B In the illustrated actuated position of the actuating element 14, the clamping leg 120 is held in the release position via the actuating element 14, in which a space within the housing 10 aligned with the plug opening 100 is released, so that an electrical line 2 enters the housing in a substantially forceless manner 10 can be plugged in like this 3A-3C is visible.

The connection terminal 1 has an in 8A-8E illustrated trigger element 13, which is supported via a support section 131 in the form of a bent tab on an edge section 111 of the contact element 11 which is bent to form the surface section 112. The support section 131 surrounds the edge section 111 of the contact element 11 and is thereby fixed to the contact element 11 and above it to the housing 10 in a torque-resistant manner.

The trigger element 13 is thus held relative to the housing 10 via the support section 131.

The trigger element 13 has a trigger leg 130 which is in a starting position (see 1A , 1B and 2A , 2 B) is extended at least approximately transversely to the plug-in direction E and so protrudes in the housing 10 into an area in the receiving space 101 that is aligned with the plug-in opening 100, so that when an electrical line 2 is inserted, it hits the trigger leg 130 with a conductor end 20 and thus the trigger element 13 affects. The support section 131 is cut free as a tab from the trigger leg 130, so that the trigger leg 130 can be deflected elastically towards the support section 131.

The trigger element 13, which is shaped as an integral leg spring, for example as a stamped and bent part, also has a locking leg 132, which is connected to the trigger leg 130 via connecting sections 134 and extends transversely to the trigger leg 130. The connecting sections 134 engage around the edge section 111 of the contact element 11, for example 1B can be seen, so that the locking leg 132 points from the edge section 111 counter to the actuation direction B in the direction of the actuating element 14.

An opening 133 is formed on the locking leg 132, which serves as a locking opening for cooperation with a locking section 143 of the actuating element 14. In the actuated position of the actuating element 14, the actuating element 14 is locked with the locking leg 132 by the locking section 143 engaging in the opening 133 on the locking leg 132, as in the transition from 1A , 1B towards 2A , 2 B is visible. In the actuated position, the actuating element 14 is thus held in position relative to the housing 10 via the triggering element 13 by the locking section 143, which is formed as a rigid projection on a body of the actuating element 14, in a form-fitting manner is engaged with the opening 133 on the locking leg 132.

Because the trigger leg 130 is connected to the locking leg 132 via the connecting sections 134, the locking leg 132 can be pivoted about the edge section 111 by actuating the trigger leg 130 in order to thereby cancel the locking between the actuating element 14 and the locking leg 132.

The triggering element 13 serves to cooperate with an electrical line 2 inserted into the plug-in opening 100 in order to automatically connect the electrical line 2 to the connecting terminal 1 by triggering the clamping leg 120. Will be an electrical line 2, like from 3A-3C can be seen, inserted into the plug opening 100, the line 2 acts with a conductor end 20 on the trigger leg 130 and deflects it out of the in 3A-3C shown, unloaded starting position, as shown 4 is visible. Together with the trigger leg 130, the locking leg 132 is thereby adjusted, with the support section 131 remaining in position on the contact element 11 and the trigger leg 130 together with the locking leg 132 being deflected elastically towards the support section 131. The locking between the actuating element 14 and the locking leg 132 is thus canceled, so that the actuating element 14 is released and so that the clamping leg 120 of the spring element 12 can move from the release position for clamping with the electrical line 2.

The trigger leg 130 defines a lever arm that is larger than the lever arm of the locking leg 132 for locking with the locking section 143 of the actuating element 14. This results in a force transmission in which an electrical line 2 with its stripped conductor end 20 exerts a comparatively small force on the trigger leg 130 can act to get this out of the in 1A , 1 B and 2A , 2 B to pivot out of the starting position shown. The locking leg 132 is pivoted in a force-translated manner, so that the locking between the locking leg 132 and the locking section 143 of the actuating element 14 is canceled.

By dimensioning the trigger leg 130 and the locking leg 132, the force transmission can be set in a suitable manner for reliable triggering when an electrical line 2 is inserted.

• Wird das Betätigungselement 14 in die Betätigungsrichtung B betätigt und dadurch in das Gehäuse 10 hinein verschoben, so nimmt das Betätigungselement 14 über den Wirkabschnitt 144 den Klemmschenkel 120 des Federelements 12 mit und verstellt den Klemmschenkel 120 dadurch in eine in 2A, 2B dargestellte Freigabestellung. In der Freigabestellung gibt der Klemmschenkel 120 einen mit der Stecköffnung 100 entlang der Steckrichtung E fluchtenden Bereich innerhalb des Aufnahmeraums 101 frei, sodass eine elektrische Leitung 2 ungehindert von dem Klemmschenkel 120 in die Stecköffnung 100 eingesteckt und somit in einer im Wesentlichen kraftlosen Weise an die Anschlussklemme 1 angeschlossen werden kann.

The result is the following functionality:

• If the actuating element 14 is actuated in the actuating direction B and thereby moved into the housing 10, the actuating element 14 takes the clamping leg 120 of the spring element 12 with it via the active section 144 and thereby adjusts the clamping leg 120 into an in 2A , 2 B Release position shown. In the release position, the clamping leg 120 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 inserted unhindered from the clamping leg 120 into the plug-in opening 100 and thus in a substantially powerless manner to the connecting terminal 1 can be connected.

By inserting it into the housing 10 in the actuation direction B, the actuating element 14 moves into the in 2A , 2 B illustrated actuated position, in which the actuating element 14 is locked via the locking section 143 with the locking leg 132 of the triggering element 13. For this purpose, the locking section 143 engages in the opening 133 on the locking leg 132 and is thus held in a form-fitting manner on the locking leg 132.

The contact element 11 forms a stop element 114 on the wall 113, with which the actuating element 14 comes into contact via a stop element 142 when the actuating element 14 is in the actuated position according to 2A , 2 B is moved. The actuated position is thus defined by striking the stop elements 114, 142 against one another. According to the actuated position 2A , 2 B In addition, the actuating element 14 cannot be adjusted further in the actuating direction B relative to the housing 10.

In the actuated, cocked position according to 2A , 2 B The connection terminal 1 can also be supplied by a manufacturer.

If an electrical line 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 clamping leg 120 is in the release position, the line arrives 2 in contact with the trigger leg 130 of the trigger element 13 and thereby pivots the trigger leg 130 within the housing 10. As a result, the locking leg 132 is adjusted relative to the locking section 143 of the actuating element 14, so that the locking leg 132 releases the locking section 143, as shown in 4 is shown. The actuating element 14 is thus released from the actuated position.

After the locking is released, the actuating element 14 arrives due to the elastic Preload on the clamping leg 120 out of the actuated position and is reset opposite to the actuation direction B, as shown 4 is visible. 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.

7A-7E show separate views of the contact element 11. The contact element 11 has a surface section 110, against which the conductor end 12 is in the clamping position due to the clamping effect of the clamping leg 120 4 is pressed, so that the line 2 is contacted with the contact element 11. The surface section 110 is bent to form the wall 113, to which the surface section 112 is also bent at an edge facing away from the surface section 110. On the wall 113, the stop element 114 is shaped in the form of a protruding tab. The edge section 111 is bent to form the surface section 112 and carries the support section 131 of the trigger element 13.

Because the actuating element 14 is automatically moved out of the actuated position after the latching is released, a user can safely and reliably recognize that the connection terminal 1 has tripped and the electrical line 2 is therefore connected to the connection terminal 1. The risk of incorrect operation is therefore reduced.

Should the electrical line 2 come from the in 4 shown connected position and removed from the connection terminal 1 again, the actuating element 14 can again be in the actuated position according to 2A , 2 B be transferred 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.

Due to the elastic support via the support section 131, the trigger element 13 returns to its starting position 2A , 2 B , so that a line 2 can be connected to the connection terminal 1 again.

The idea on which the invention is based is not limited to the exemplary embodiment described above, but can also be implemented in other ways.

The actuating element can be biased towards the non-actuated position by the action of the clamping leg of the spring element. However, it is also conceivable to provide an additional biasing element, which biases the actuation element against the actuation direction in the direction of the non-actuated position relative to the housing. Such a biasing element can be designed, for example, by a compression spring or another mechanical spring.
