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 is pivotally mounted on the housing and which has a triggering leg and an active leg, the actuating element being locked in the actuated position relative to the housing, so that the actuating element is held in position relative to the housing in the actuated position. The triggering element can be pivoted relative to the housing when the triggering leg interacts with the electrical line when it is inserted into the plug-in opening. The active leg is designed to act on the actuating element to release the actuating element from the actuated position when the triggering element is pivoted.

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 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 pivotally mounted on the housing, 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 it is inserted into the plug-in opening plugged-in electrical cable is electrically contacted with the contact element of the connection terminal. 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 element is pivoted towards the housing, so that the trigger element acts on the actuating element via the active leg, so that the locking of the actuating element is canceled and the actuating element is thus released from the actuated position.

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

Because the trigger element is pivoted towards the housing when the electrical cable is inserted and thereby acts on the actuating element in order to release it from the latching position in the actuated position, 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 triggering element can be pivoted to the housing via the triggering leg, so that when interacting with the electrical line, the triggering leg is moved out of the starting position and the triggering element is thereby adjusted to act on the actuating element.

The trigger leg can, for example, define a lever arm that is larger than the lever arm of the active 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. The trigger element then acts on the actuating element via the active leg with a force transmission determined by the lever ratio in order to release it from the locking position in the actuated 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 hold the electrical line in by spring force To pull the system with the contact element. 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 has a pass-through opening through which the spring element reaches. The spring element can be formed, for example, by a curved sheet metal spring, in which the clamping leg can be deflected along an adjustment plane relative to the support leg. The spring element extends through the passage opening of the actuating element, for example around a housing section of the housing, so that the spring element is supported via the support leg on the housing on a first side of the actuating element 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 position due to the spring preload of the spring element.

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 a latching element of the housing in the actuated position. The latching section can, for example, be arranged at an end of the actuating element facing away from the actuating section. Via the locking section, the actuating element is locked in the actuated position with an associated locking element of the housing, so that the actuating element is held in the actuated position, but can be released from the actuated position in a simple, reliable manner by triggering the triggering element when the electrical cable is plugged in can.

In one embodiment, the latching section of the actuating element is elastically adjustable relative to the actuating section. The latching section can be formed, for example, by an elastic finger which extends linearly from the actuation section, for example along an actuation direction along which the actuation element is displaceable relative to the housing. The locking section can, in one embodiment, be adjusted, for example, transversely to the actuation direction relative to the actuation section in order to be elastically deflected when the actuation element is transferred into the actuated position to snap into engagement with the latching element of the housing, the actuating element being able to be released again from the actuated position by acting on the latching section of the triggering element.

If a pass-through opening is formed in the actuating element, through which the spring element engages, the pass-through opening can extend into the area of the latching section, so that a material weakening is produced in the area of the latching section and this is therefore flexurally elastic, in particular transversely to the actuation direction relative to the actuating section can be deformed.

In one embodiment, the latching element of the housing is formed by an engagement projection projecting from a housing wall of the housing. The engagement projection can in particular be rigidly formed on the housing, so that the engagement projection cannot be deflected relative to the housing wall. Elasticity for producing the latching connection of the actuating element in the actuated position is thus provided via the latching section of the actuating element, which engages in a latching manner with the engagement projection of the latching element when the actuating element is transferred into the actuated position and is disengaged to release the actuating element from the actuated position can be brought by the engagement projection.

The engagement projection projects from the housing wall and preferably forms an undercut for locking with the locking section of the actuating element. The engagement projection can, for example, be formed on a side wall of the housing, wherein in one embodiment two engagement projections can be provided on opposite side walls spaced apart transversely to the direction of actuation for locking with the locking section of the actuating element in the actuated position. If the connection terminal is designed to be lined up with further connection terminals, a second engagement projection can also be arranged on a rear wall of an adjacent connection terminal that is parallel to the side wall of the housing of the present connection terminal.

In one embodiment, the active leg is designed to act on the locking section when the trigger element is pivoted in order to lift the locking section away from the engagement projection. The active leg can, for example, be extended approximately at a right angle to the trigger leg. When the trigger element is pivoted, caused by an electrical line on the trigger leg, the active leg is pivoted and thereby acts on the locking section of the actuating element, for example to lift it transversely to the actuating direction from the locking element formed by the engagement projection. The locking of the locking section with the locking element is thus released.

In one embodiment, the actuating element has a guide surface which is guided in a linearly displaceable manner on a guide section of the housing. The guide surface can be formed, for example, by a flat wall of the actuating element, which extends, for example, along a plane spanned by the actuation direction and a transverse direction. In contrast, the guide section on the housing can be formed, for example, by a guide edge which extends along the actuation direction within the housing and provides a guide for the actuating element on a displacement path in the housing.

1A , 1B until 4A , 4B 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 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 .

The spring element 12 has a support leg 121, which is supported on a wall of the housing 10, 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 relative to the support leg 121, in particular in such a way that the clamping leg 120 is in an in 4A , 4B 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 7A , 7B 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. In addition, the actuating section 141 forms a guide surface 140, which is guided in the actuating direction B beyond the guide opening 102 on a guide section 106 in the form of a step-shaped guide edge in the interior 101 of the housing 10, so that the actuating element 14 moves linearly along its entire displacement path in the housing 10 the housing 10 is guided.

The actuating element 14 is in operative connection with the clamping leg 120 of the spring element 12. This applies to this 9A , 9B Spring element 12 shown in separate views has a pass-through opening 142 within the actuating element 14 such that the spring element 12 engages with an intermediate section 122 around a peg-shaped housing section 104 of the housing 10. The support leg 121 protrudes from 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 purposes with the contact element 11 and can also act for mechanical locking.

The connection terminal 1 has an in 8A , 8B illustrated trigger element 13, which is pivotally mounted on the housing 10 via a bearing axis 131. In the exemplary embodiment shown, the bearing axis 131 is formed in a fixed manner on the housing 10 and protrudes from a side wall 105 of the housing 10 (if the housing 10 is closed by a cover parallel to the side wall 105, the bearing axis 131 extends between the side wall 105 on one side of the housing 10 and the cover on the other side of the housing 10). The bearing axis 131 passes through a bearing opening 133 of the trigger element 13 (see 8A , 8B) and pivotably mounts the trigger element 13 on the housing 10.

The trigger element 13 has a trigger leg 130 which is in a starting position (see 1A , 1 B and 2A , 2 B) at least approximately transverse to the plugging direction E is extended and so protrudes in the interior 101 of the housing 10 into an area aligned with the plug-in opening 100 that when an electrical line 2 is inserted, it hits the trigger leg 130 with a conductor end 20 and thus acts on the trigger element 13.

As can be seen from the separate views of the housing 10 5A , 5B As can be seen, in the illustrated embodiment, a locking element 103 is formed on the side wall 105 in the form of a rigid engagement projection, which serves to lock the actuating element 14 in the actuated position relative to the housing 10. The actuating element 14 has a locking section 143 in the form of an elastic locking finger, which extends linearly along the actuation direction B from the actuating section 141 and in the area of which the through opening 142 also extends, through which the spring element 12 engages. The latching section 143 can be deflected elastically to the actuating section 141 transversely to the actuation direction B and can thereby latch with the latching element 103 on the housing 10 (the housing 10 is secured to the housing 10 by a cover parallel to the side wall 105). 2A , 2 B closed on the front side, locking elements 103 can be formed both on the side wall 105 and on the lid, so that the locking section 143 is locked on one side on the side wall 105 and on the other side on the lid). In an actuated position, shown in 2A , 2 B the actuating element 14 is locked relative to the housing 10 and is thus held in position relative to the housing 10 in the actuated position.

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. The triggering element 13 has an active leg 132, which is designed to interact with the locking section 143 when the triggering element 13 is pivoted about the bearing axis 131 and thus to release the actuating element 14 from the locking in the actuated position. When the trigger element 13 is pivoted about the bearing axis 131, the active leg 132 acts on the locking section 143 in order to lift it from the locking element 103 transversely to the actuation direction B and thus cancel the locking, so that the actuation element 14 is reset in the housing 10 against the actuation direction B can be.

The trigger leg 130 defines a lever arm that is larger than the lever arm of the active leg 232 for acting on 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 active leg 132 acts on the latching section 143 in a force-translated manner and thereby brings the latching section 143 out of engagement with the latching element 103.

By dimensioning the trigger leg 130 and the active 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 einen 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 an 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.

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 element 13 about the bearing axis 131 within the housing 10. As a result, the active leg 132 is adjusted relative to the latching section 143 of the actuating element 14, so that the active leg 132 acts on the latching section 143 and the locking section 143 is moved out of engagement with the locking element 103 on the housing 10, as shown in FIG 3A , 3B and 4A , 4B is shown. The actuating element 14 is thus released from the actuated position.

After the locking is released, the actuating element 14 moves out of the actuated position due to the elastic pretension on the clamping leg 120 and is reversed reset to the actuation direction B, as shown 4A , 4B 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.

6A , 6B 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 4A , 4B is pressed, so that the line 2 is contacted with the contact element 11. The contact element 11 can be contacted, for example, with a busbar or another associated electrical assembly via a contact section 111.

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 4A , 4B 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.

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 trigger element can be pivotally mounted on the housing or on a component stationary to the housing via a bearing axis. The triggering element can, for example, be elastically biased towards the starting position via a prestressing element, for example a spring, so that the triggering element automatically returns to its starting position after the actuating element has been triggered.

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.
