Description

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 line can be inserted along a plug-in direction for connecting to the connection terminal. A contact element is arranged on the housing and has a contact section for electrical contact with the electrical line. A spring element is also arranged on the housing 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 section of the contact element when the electrical line is inserted into the plug-in opening. An actuating element can be actuated by a user in order to move the clamping leg into a release position in which a space within the housing is released in order to enable a simple connection of a line or to be able to remove a connected line again. 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 adjust the clamping leg to facilitate insertion of the electrical cable into the plug-in opening or to remove the electrical cable from the plug-in opening.

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.

From the WO 2021/095676 A1 a connection terminal with a spring element is known which has a clamping leg which is locked in a release position with a latching element.

From the DE 10 2016 108 826 A1 is a connection terminal with at least one housing, at least one conductor insertion opening formed in the housing, at least one current bar arranged in an interior of the housing, at least one clamping spring arranged in the interior of the housing for clamping a conductor inserted via the conductor insertion opening of the housing, and at least one pivotable known in the housing mounted actuating element for transferring the clamping spring into an open position and into a closed position. The actuating element has a locking area by means of which the actuating element is locked in the open position by forming a positive connection with the current bar and by means of which the actuating element is locked in the closed position by forming a positive connection with the housing.

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 comprises a trigger element arranged adjustably on the housing and a latching section formed on the housing. The actuating element has a latching element which is latched to the latching section in the release position of the clamping leg, so that the clamping leg is held in position relative to the housing in the release position. The trigger element has a run-up section and a release section. The casserole section is designed to interact with the electrical line on a first side of the contact section for adjusting the triggering element relative to the housing when the electrical line is inserted. The release section is designed to interact with the latching element of the actuating element on a second side of the contact section facing away from the first side in order to release the latching of the latching section of the housing.

In the connection terminal, the electrical line is electrically contacted with the electrical contact element in that when the electrical line is inserted into the plug-in opening, the clamping leg acts on the electrical line and loads it resiliently in the direction of contact with the contact section of 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 be adjusted to the housing, for example by user operation, in order to act on the clamping leg and to adjust the clamping leg in the direction of the release position.

By activating the actuating element, the clamping leg can be moved into the release position. In the release position, the clamping leg is indirectly locked relative to the housing via the actuating element, so that the clamping leg is held in position relative to the housing in the release position. After being transferred to the release position, the clamping leg thus remains in the release position, so that an electrical line can be easily connected to the connection terminal or a connected electrical line can be removed from the connection terminal.

With the clamping leg in the release position, the connecting terminal can also be delivered to a customer by a manufacturer, for example.

The connection terminal has a trigger element which is adjustable on the housing and is used to interact with an electrical line when it is inserted into the plug-in opening. The trigger element is designed to cooperate with the latching element of the actuating element in order to disengage it from the latching portion of the housing and thereby release the latching between the latching element of the actuating element and the latching portion of the housing. By adjusting the triggering element when the electrical cable is inserted, the locking is canceled so that the clamping leg moves out of its release position and thus acts in a clamping manner on the electrical cable inserted into the plug-in opening, which has triggered the triggering element, and the electrical cable thereby contacts the contact element .

To interact with the electrical line, the triggering element has a run-up section onto which the electrical line runs when inserted into the plug-in opening and thus adjusts the triggering element. In addition, the trigger element has a release section which is designed to act on the locking element of the actuating element. The triggering element is arranged relative to the contact section of the contact element in such a way that the electrical line interacts with the run-up section of the triggering element on a first side of the contact section when it is inserted into the plug-in opening, in order to thereby adjust the triggering element. When adjusting the triggering element, the release section cooperates with the locking element of the actuating element on a second side of the contact section facing away from the first side in order to disengage it from the locking section of the housing and thus release the actuating element from its locked position.

By inserting the electrical cable, the triggering element is thus adjusted relative to the contact section. While the electrical line is on the first side of the contact section interacts with the triggering element, the triggering element acts on the locking element of the actuating element on the second side of the contact section facing away from the first and thus releases it from its locked position. The actuating element and thus the clamping leg are thereby released, so that the clamping leg moves from the release position into a clamping position for clamping the inserted electrical line with the contact section of the contact element.

Because the trigger element is adjusted to the housing when the electrical cable is inserted, 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 trigger element has a trigger leg that is elastically adjustable relative to the housing. The run-up section and the release section are formed on the release leg, for example on a free end of the release leg.

Preferably, the trigger leg is attached to the housing in an elastically adjustable manner. For this purpose, the trigger leg can, for example, be formed in one piece with a wall of the housing, so that the trigger element is an integral part of the housing. The run-up section and the release section are formed here, for example, at a free end of the trigger leg, which lies away from a fastening point at which the trigger leg is connected to the housing.

For example, the trigger leg extends longitudinally along the insertion direction. While the trigger leg can be designed to be essentially rigid along the plug-in direction, the trigger leg is preferably elastically adjustable relative to the housing transversely to the plug-in direction, so that when the electrical cable is inserted in the plug-in direction into the plug-in opening on the housing, the cable with one conductor end is placed on the casserole section runs up on the trigger leg and thereby adjusts the trigger leg transversely to the insertion direction relative to the contact section. While the line interacts with the casserole section on the first side of the contact section, the trigger leg acts on the locking element of the actuating element on the second side facing away from the first side and thereby releases the locking between the actuating element and the housing.

The latching element of the actuating element can, for example, be shaped so that it can be elastically deflected on the actuating element, for example on an actuating section of the actuating element. In contrast, the locking section of the housing is, for example, rigidly formed on the housing, for example in the form of an undercut on the housing.

In one embodiment, the triggering element engages in an opening of the contact section such that the run-up section protrudes from the contact section on the first side in a starting position of the triggering element. The trigger element thus lies in an opening in the contact section. In an unloaded starting position, the triggering element protrudes from the contact section with the casserole section, which is preferably formed on an elastic triggering leg, so that when an electrical cable is inserted into the plug-in opening, the line with one conductor end runs onto the casserole section and thereby adjusts the triggering element.

In one embodiment, the contact section extends flatly along a plane that is spanned by the plug-in direction and a transverse direction pointing transversely to the plug-in direction. The electrical line is pressed against the contact section with a (stripped) conductor end when the electrical line has been inserted into the plug-in opening and the clamping leg has been moved from the release position into a clamping position. Contact is thus made between the line and the contact element via the contact section, in that the line makes electrical contact with the contact section.

In this case, the casserole section protrudes relative to the contact section in a starting position along a vertical direction which is perpendicular to the transverse direction and to the plug-in direction. Preferably, the triggering element is adjustable along the vertical direction relative to the contact section, so that the triggering element is adjusted essentially perpendicular to the plane of the contact section when the electrical line is inserted, in order to thereby act on the locking element of the actuating element on the second side facing away from the first side and the To release the locking of the actuating element.

The spring element can, for example, have a support leg, via which the spring element is supported on the housing and held in position on the housing. The clamping leg can be deflected elastically relative to the support leg, with the clamping leg being deflected in the release position in such a way that the spring element is elastically tensioned and the clamping leg is elastically preset after being released from the release position is moved in a tensioned manner out of the release 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 section of 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 section of 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 section of the contact element.

In one embodiment, the actuating element is pivotally mounted relative to the housing. The actuating element can, for example, have a pivotably mounted bearing element and can therefore be moved along a curved actuation direction towards the housing. For example, a pivot axis of the actuating element can be directed along the transverse direction (along which the flat contact section of the contact element extends).

In one embodiment, the bearing element is arranged on the first side of the contact section and the locking element on the second side of the contact section. The bearing element and the locking element are thus arranged on different sides of the contact section. While the actuating element is pivotally mounted via the bearing element on the first side of the contact section, the locking between the actuating element and the housing takes place on the second side of the contact section. This makes it possible to create a locking mechanism with a comparatively large lever arm, which enables reliable locking with comfortable operation.

The actuating element is pivotable relative to the housing. The actuating element can be mounted directly on the housing or on another component connected to the housing. For example, the spring element can have a bearing section on which the bearing element of the actuating element is arranged and via which the actuating element is thus pivotably mounted to the housing. The bearing section can, for example, be arranged between the clamping leg of the spring element and the support leg and be formed by a bent section of the spring element, which surrounds the bearing element of the actuating element and thus provides a sliding bearing for the bearing element.

The mounting of the actuating element on the spring element makes it possible, in particular, to provide a common pivot point for the actuating element and the clamping leg of the spring element. When pivoting the actuating element, the clamping leg is pivoted about the same pivot point with the actuating element, which enables an advantageous introduction of force from the actuating element into the clamping leg (and vice versa).

In one embodiment, the actuating element has an actuating section arranged on the second side of the contact section for actuation by a user. The actuation section can be actuated from outside the housing, in particular manually or using a tool. While the line is contacted with the contact element on the first side of the contact section within the housing, the actuating section for actuating the actuating element on the second side of the contact section is preferably arranged outside the housing, so that the actuating element can be operated by a user relative to the housing via the actuating section can be moved, in particular to move the clamping leg into the release position.

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 in the illustrated embodiment is supported on a surface section 113 of the contact element 11, 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 The clamping position shown acts clampingly on an electrical line 2 connected to the connection terminal 1 and presses it under elastic prestress into contact with a contact 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 that it can pivot along a curved actuation direction B. In the exemplary embodiment shown, the actuating element 14 is designed as a pivoting lever which is received and pivotally mounted on a bearing section 122 of the spring element 12 via a bearing element 140. The bearing section 122 connects to the support leg 121 and merges into the clamping leg 120 and is bent so that a sliding bearing for the bearing element 140 is formed inside and thus the bearing element 140 is pivotally mounted on the bearing section 122.

The actuating element 14 has a lever arm 143 which connects the bearing element 140 inside the housing 10 with an actuating section 141 outside the housing 10. By actuating the actuation section 141, a user can move the actuation element 14 along the actuation direction B and thereby pivot it relative to the housing 10.

The lever arm 143 is slidably guided on a guide device 103 in the form of a guide edge on the housing 10, as is the case in the transition from 1A , 1B towards 2A , 2 B is visible.

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. By pivoting the actuating element 14 in the actuating direction B, the clamping leg 120 is moved into the release position, as in the transition from 1A , 1B towards 2A , 2 B visible.

In the in 2A , 2 B In the illustrated, actuated position of the actuating element 14, the clamping leg 120 has been moved into the release position, in which a space within the housing 10 aligned with the plug-in opening 100 is released, so that an electrical line 2 can be inserted into the housing 10 in a substantially powerless manner can look like this 3A , 3B is visible.

The actuating element 14 has a locking element 142 formed on the actuating section 141, for example in the form of a hook, which is in the release position of the clamping leg 120 according to 2A , 2 B is engaged with a locking section 102 on a housing wall of the housing 10. While the locking element 142 can be deflected elastically relative to the actuating section 141, the locking section 102 is shaped as a rigid undercut on the housing wall. When the clamping leg 120 is moved into the release position, the latching element 142 thus runs onto the latching section 102 and is deflected until, after passing through the latching section 102, the latching element 142 snaps into engagement with the latching section 102, as is the case 2A , 2 B is visible.

In the actuated position according to 2A , 2 B is the actuating element 14 with the Housing 10 latches so that the clamping leg 120 of the spring element 12 is held in the release position.

The connection terminal 1 has a trigger element 13, which forms a trigger leg 130, which is formed integrally and in one piece with a housing wall 104 of the housing 10 and carries a run-up section 131 and a release section 132 at a free end. The trigger element 13 is thus arranged on the housing 10, but can be deflected elastically along a vertical direction V. The triggering element 13 can be formed, for example, by a spring tongue extending longitudinally along the plug-in direction E, which is connected at one end to the housing wall 104 and carries the run-up section 131 and the release section 132 at its free end.

The contact section 110 of the contact element 11 extends flatly along a plane which is spanned by the plug-in direction E and a transverse direction Q pointing transversely to the plug-in direction E. The vertical direction V is perpendicular to this plane. The triggering element 13 is arranged relative to the contact section 110 in such a way that the triggering element 13 engages in an opening 111 in the area of the contact section 110.

In an unloaded starting position, shown in 2A , 2 B , the trigger element 13 is arranged in relation to the contact section 110 in such a way that the run-up section 131 protrudes along the vertical direction V relative to the contact section 110 and thus protrudes into the receiving space 101 inside the housing 10.

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 , 3B can be seen, inserted into the plug opening 100, the line 2 acts with a conductor end 20 on the run-up section 131 on the trigger leg 130 and deflects it out of the in 2A , 2 B shown starting position, like this 3A , 3B is visible. The release leg 130 thereby acts with the release section 132 on the locking element 142 of the actuating element 14 and lifts it out of engagement with the locking section 102 of the housing, as shown 3A , 3B is visible. The locking between the actuating element 14 and the housing 10 is thus canceled, so that the actuating element 14 can move out of the actuated position and the clamping leg 120 thus moves into clamping contact with the electrical line 2, as shown 4A , 4B is visible.

The run-up section 131 is shaped on the trigger leg 130 of the trigger element 13 in such a way that the run-up section 131 protrudes from the contact section 110 on a first side when the trigger element 13 is in the in 2A , 2 B shown, unloaded starting position. With a casserole oriented obliquely to the plug-in direction E, the casserole section 131 points counter to the plug-in direction E, so that the electrical cable 2 can run onto the casserole section 131 when it is inserted into the plug-in opening 100.

In contrast, the release section 132 acts on the locking element 142 of the actuating element 14 on a second side of the contact section 110 facing away from the first side in order to cancel the locking between the actuating element 14 and the housing 10 on this second side of the contact section 110. When the electrical cable is inserted, the trigger element 13 is pushed outwards along the vertical direction V and thus lifts the locking element 142 from the locking section 102 of the housing, so that the locking is canceled.

• Wird das Betätigungselement 14 in die Betätigungsrichtung B betätigt und dadurch zu dem Gehäuse 10 verschwenkt, so nimmt das Betätigungselement 14 über den Wirkabschnitt 144 den Klemmschenkel 120 des Federelements 12 mit und verstellt den Klemmschenkel 120 dadurch in die 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 pivoted towards 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 the 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.

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 clamping leg 120 is in the release position, the line 2 comes into contact with the run-up section 131 of the trigger leg 130 of the trigger element 13 and thereby deflects the trigger leg 130 relative to the housing 10. The Trigger element 13 thereby acts on the latching element 142 of the actuating element 14 and releases the latching between the actuating element 14 and the latching section 102 of the housing 10, so that the actuating element 14 is released from the latched, actuated position.

After the locking is removed, 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 section 110 of the contact element 11, so that the line 2 is electrically connected to the connection terminal 1 and is also mechanically locked. Due to the elastic preload on the clamping leg 120, the actuating element 14 is also taken along and reset against the actuation direction B, as shown 4A , 4B is visible.

In the connected position, the conductor end 20 of the line 2 is pressed against the contact section 110 of the contact element 11 by the clamping effect of the clamping leg 120, so that the line 2 is contacted with the contact element 11. The contact element 11 is shaped, for example, as a sheet metal element and has a surface section 113 which is bent over to form the contact section 110 and on which the support leg 121 of the spring element 12 is supported. A connection element 112 is connected to the surface section 113, via which the connection terminal 1 can be arranged, for example, on a circuit board and can be electrically contacted with the circuit board.

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 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.
