Description

The invention relates to a conductor connection terminal with an insulating material housing, the insulating material housing having a conductor insertion opening for inserting an electrical conductor in a conductor insertion direction, with a busbar and with a clamping spring, the clamping spring having a clamping leg which, together with the busbar, forms a clamping point for the electrical conductor , And with an actuating element, wherein the actuating element is slidably mounted in the insulating housing and is designed to open and / or close the terminal point.

DE 10 2008 039 232 A1 discloses a conductor connection terminal with a busbar and a clamping spring, the busbar and the clamping spring forming a clamping point for an electrical conductor to be clamped. The clamping point can be opened by an actuating element mounted in an insulating material housing.

Proceeding from this, it is the object of the present invention to create an improved conductor connection terminal.

The object is achieved with a conductor terminal with the features of claim 1. Advantageous embodiments are described in the dependent claims.

In the case of the conductor connection terminal of the generic type, it is proposed that the actuating element has an opening for receiving a projection of the insulating material housing.

By receiving the projection in the opening of the actuating element, a captive actuating element can be provided. Captive means that the actuating element cannot be removed from the conductor connection terminal without external influence. In particular, the opening is sufficiently large for the actuating element to be mounted in a sufficiently displaceable manner in order to open and/or close the clamping point. The projection is surrounded in particular by the opening of the actuating element. It is conceivable that the projection extends completely through the opening.

The actuating element can in particular be mounted in the insulating material housing so that it can be displaced from an initial position into an actuating position. The initial position is the position in which the clamping point is completely closed. The operating position is the position in which the clamping point is fully open.

A projection can in particular be a material projection of the insulating material housing. The opening can be a corresponding material recess, the opening being designed to be so large that the actuating element can be transferred from the initial position to the actuating position.

The actuating element can have a pressure section, with two opposite, spaced-apart side elements forming an intermediate space protruding from the pressure section, and an actuating section for opening and/or closing the clamping point being arranged on the ends of the side elements opposite the pressure section, with the side elements having an opening for receiving the Form projection of the insulating material.

The projection of the insulating material housing can thus be surrounded in particular by the pressure section, the two opposite side elements and the actuating section, so that a simply constructed conductor terminal is provided, the actuating element being captively mounted on the insulating material housing.

The actuation section is in particular the section that can interact with the clamping spring, so that the actuation section bears against the clamping leg to open the clamping point. During the actuation process, the clamping leg is thus displaced into an open position by the actuation section.

The pressure section is in particular the section that is used by a user to actively move the actuating element. This can be done directly by the user, for example, by the user exerting a force on the pressure section, or indirectly via an actuating tool.

The side elements can be disc-shaped. It is also advantageous if the side elements are aligned essentially parallel to one another. Essentially means in particular that the side elements do not have to be aligned exactly parallel. A deviation of up to five degrees, based on a 360° system, from exact parallelism is conceivable.

An actuation section can be arranged on the actuation element, which actuation section is set up for manual actuation of the actuation element, the actuation section protruding from the pressure section in the conductor insertion direction. In particular, between the operating section and an outer wall of the insulating material housing can be accommodated in the side elements.

For example, the actuation portion may be oriented substantially perpendicular to the pressure portion. The actuation section and/or the pressure section can be oriented essentially at right angles to the side elements.

In this way, a sliding operation can be provided. Due to the design of the operating section and mounting on the outside of the insulating material housing, the user can move the operating element by moving the operating section on the insulating material housing.

A pin can be arranged on the actuating element, the pin being slidably received in a recess of the insulating material housing. The pin does not have to be accommodated in the recess in every actuation state of the actuating element or can only be partially accommodated therein depending on the actuation state. In an advantageous embodiment, it is provided that the pin is accommodated at least to a significant extent in the recess, at least when the actuating element is fully actuated, when the clamping point is opened by the actuating element. In this way, a form-fitting coupling between different parts of the insulating material housing can be realized by the pin and the recess, e.g. between a main housing part and a cover part of the insulating material housing. In this way, the pin and the recess hold the housing-cover latching together at least when the actuating element is fully pressed.

• Leiteranschlussklemme mit einem Isolierstoffgehäuse, wobei das Isolierstoffgehäuse eine Leitereinführungsöffnung zum Einführen eines elektrischen Leiters in einer Leitereinführungsrichtung hat, mit einer Stromschiene und mit einer Klemmfeder, wobei die Klemmfeder einen Klemmschenkel hat, der mit der Stromschiene eine Klemmstelle für den elektrischen Leiter bildet, und mit einem Betätigungselement, wobei das Betätigungselement verschiebbar in dem Isolierstoffgehäuse gelagert ist und zum Öffnen und/oder Schließen der Klemmstelle eingerichtet ist, wobei an dem Betätigungselement ein Zapfen angeordnet ist, wobei der Zapfen in einer Ausnehmung des Isolierstoffgehäuses verschieblich aufgenommen ist. Ferner vorteilhaft kann der Zapfen am Druckabschnitt und die Ausnehmung am Vorsprung des Isolierstoffgehäuses angeordnet sein, wobei der Zapfen in Leitereinführungsrichtung von dem Betätigungselement abragt.

The design of the pin is independent of the present invention and can be regarded as an independent invention. A conductor connection terminal with the following features is therefore also conceivable:

• Conductor connection terminal with an insulating material housing, wherein the insulating material housing has a conductor insertion opening for inserting an electrical conductor in a conductor insertion direction, with a busbar and with a clamping spring, the clamping spring having a clamping leg which, together with the busbar, forms a clamping point for the electrical conductor, and with a Actuating element, wherein the actuating element is slidably mounted in the insulating material housing and is set up to open and/or close the terminal point, a pin being arranged on the actuating element, the pin being slidably received in a recess of the insulating material housing. Further advantageously, the pin can be arranged on the pressure section and the recess can be arranged on the projection of the insulating material housing, the pin protruding from the actuating element in the conductor insertion direction.

By forming a pin, the actuating element and the insulating housing are held together during actuation. Furthermore, the actuating element is guided linearly into the actuating position and back into the starting position, so that the actuating element can be guided in the insulating material housing without tilting.

The insulating housing can have a first housing part and a second housing part. Further advantageously, the pin can be accommodated in the recess of the actuating element when the clamping point is open. For example, the first housing part can be a main housing part, and the second housing part can be a cover part.

Due to the two-part design of the insulating material housing, the conductor connection terminal according to the invention can be installed in a simple manner by first inserting a contact insert into the first housing part and then terminating the second housing section of the insulating material housing. The two housing parts are held together against the spring force of the clamping spring by the formation of the projection and the reception of the projection in the opening of the actuating element. This effect is further improved by the formation of the aforementioned pin on the actuating element, the pin being slidably received in the recess of the insulating material housing, in particular when the clamping point is open, in the recess of the projection.

A spring element can be arranged in the area of the recess, with a restoring force from the spring element acting on the actuating element when the clamping point is open.

In particular, the spring element is mounted within the recess. The spring element is thus a spring element separate from the clamping spring, the spring element enabling the actuating element to be reset from the actuating position, in which the clamping point is open, into the starting position, in which the clamping point is closed.

It is conceivable that the actuating element is only reset as long as the actuating element is not latched in the actuating position. The conductor terminal thus has a spring element, which is in addition to the terminal leg the clamping spring is present, wherein the actuating element can be guided back into the starting position via the spring element.

The actuating element can extend essentially parallel to the conductor insertion direction. In particular, the longitudinal extension direction of the actuating element extends parallel to the conductor insertion direction. The direction of longitudinal extension is the direction in which the actuating element has the longest dimension.

Substantially parallel means in particular that the actuating element does not have to be arranged exactly parallel to the conductor insertion opening. It is conceivable, for example, that a deviation of up to five degrees from exact parallelism is possible.

Due to the parallel design, the actuating element can be guided parallel to the conductor entry, as a result of which the introduction of the electrical conductor cannot be blocked by the actuating element. The actuating element can be guided over a conductor entry area, for example, without protruding into the conductor entry area.

The clamping spring can have a contact leg for contact with the conductor rail, a spring bow being arranged between the contact leg and the clamping leg.

The contact leg is designed in particular for contact with a part of the conductor connection terminal. The contact leg is preferably designed for contact with the conductor rail. As a result, a self-supporting clamping spring can be provided, for example.

A first retaining element and a second retaining element can be arranged on the contact leg, the first retaining element being mounted on a first retaining edge of the conductor connection terminal and the second retaining element being mounted on a second retaining edge of the conductor connection terminal.

The formation of the first holding element and the second holding element on the contact leg and a corresponding first holding edge and second holding edge is independent of the present invention and can be regarded as an independent invention. A conductor connection terminal with the following features is therefore also conceivable:

• Conductor connection terminal with an insulating material housing, wherein the insulating material housing has a conductor insertion opening for inserting an electrical conductor in a conductor insertion direction, with a busbar and with a clamping spring, the clamping spring having a clamping leg and a contact leg for contact with the busbar, with between the contact leg and the clamping leg a spring bow is arranged, with the clamping limb forming a clamping point for the electrical conductor with the busbar, and with an actuating element, with the actuating element being slidably mounted in the insulating material housing and being set up to open and/or close the clamping point, with a first retaining element and a second retaining element is arranged, wherein the first retaining element is mounted on a first retaining edge of the conductor terminal and the second retaining element on a second retaining edge of the conductor terminal.

The two-part connection of the clamping spring makes it possible in particular to achieve a stable connection to the conductor connection terminal, with long and free elastic mobility of the clamping spring being ensured at the same time.

The first holding element and the second holding element can be projected out of the contact leg in a direction pointing away from the clamping leg of the clamping spring. Further advantageously, the first holding element and/or the second holding element can be arranged at the free end of the contact leg.

As a result, the connection of the clamping spring to the conductor connection terminal can be further improved, the mobility of the clamping spring being able to be improved by the arrangement of the holding elements at the free end of the contact leg.

The first holding edge and/or the second holding edge can be designed as the edge of a holding opening of the conductor connection terminal, with the first holding element and/or the second holding element reaching through the holding opening.

By designing the holding edges as the edge of a holding opening, the first holding element and/or the second holding element can be surrounded by the holding opening on the peripheral side, as a result of which an improved connection of the clamping spring can be achieved. It is also conceivable that only the first holding edge or the second holding edge is designed as the edge of a holding opening.

The first holding edge and/or the second holding edge can be arranged on the conductor rail.

It is conceivable that the first holding element engages behind the first holding edge on the busbar. In the direction of the spring arc, the second holding element is arranged at a distance from the first holding element and is supported on the second holding edge of the conductor rail or, for example, reaches through one of the holding openings described above. The first holding element can thus be arranged, for example, at the free end of the contact leg, the second holding element being arranged at a distance from the first holding element in the direction of the spring bow. It is conceivable that at least part of the busbar engages over the clamping spring or rests on it.

The actuating element can be mounted in a bearing point on the insulating material housing in such a way that the actuating element can be tilted about the bearing point into a latching position or out of the latching position.

• Leiteranschlussklemme mit einem Isolierstoffgehäuse, wobei das Isolierstoffgehäuse eine Leitereinführungsöffnung zum Einführen eines elektrischen Leiters in einer Leitereinführungsrichtung hat, mit einer Stromschiene und mit einer Klemmfeder, wobei die Klemmfeder einen Klemmschenkel hat, der mit der Stromschiene eine Klemmstelle für den elektrischen Leiter bildet, und mit einem Betätigungselement, wobei das Betätigungselement verschiebbar in dem Isolierstoffgehäuse gelagert ist und zum Öffnen und/oder Schließen der Klemmstelle eingerichtet ist, wobei das Betätigungselement in einem Auflagerpunkt an dem Isolierstoffgehäuses derart gelagert ist, dass das Betätigungselement um den Auflagerpunkt in eine Rastposition oder aus der Rastposition kippbar ist.

The formation of the support point is independent of the present invention and can be regarded as an independent invention. A conductor connection terminal with the following features is therefore also conceivable:

• Conductor connection terminal with an insulating material housing, wherein the insulating material housing has a conductor insertion opening for inserting an electrical conductor in a conductor insertion direction, with a busbar and with a clamping spring, the clamping spring having a clamping leg which, together with the busbar, forms a clamping point for the electrical conductor, and with a Actuating element, wherein the actuating element is movably mounted in the insulating material housing and is set up to open and/or close the clamping point, wherein the actuating element is mounted in a bearing point on the insulating material housing in such a way that the actuating element can be tilted about the bearing point into a latching position or out of the latching position is.

A tilting movement takes place in particular as a rotation through a small angle of rotation. This means that the actuating element can tilt by up to 45°, in particular by up to 25°, in order to get into the locking position or to be guided out of the locking position. In contrast to the tilting movement, there is a pivoting movement, which is basically used in actuating levers, by a larger angle of rotation. During the pivoting movement, the angle of rotation is greater than 60°. A tilting of the actuating element thus takes place by a smaller angle than a pivoting of the actuating element.

Furthermore, no opening and/or closing of the clamping point results from the tilting movement according to the invention. The actuating element is moved into a latching position or out of the latching position by the tilting movement about the support point, so that the actuating element can be held in an open position of the clamping point. In the case of a pivoting movement of an actuating lever, on the other hand, the pivoting movement results in an opening or closing of the clamping point. In contrast, in the case of the present invention, the opening and/or closing of the clamping point results from a displacement of the actuating element.

The support point can be arranged, for example, on a contour of the insulating material housing, for example in an actuation channel, with the actuation element being movably mounted in the actuation channel. The actuating element can be tilted about this support point, so that the actuating element can be guided into or out of the latching position.

The detent position is the position in which the actuating element is held in the actuating position, i.e. with the clamping point open, without external force being applied. This can be done, for example, by the clamping force of the clamping leg of the clamping spring, with the actuating element being held in the locking position by the spring force.

It is conceivable that the actuating element can be guided out of the locking position by an actuating tool, for example, by being tilted back around the support point.

The actuating element can be embodied as a sliding actuation, the sliding actuation having a sliding section which is at least partially supported by a contact surface on the insulating material housing. Sliding actuation provides an alternative actuation option to push-button actuation, it being possible for the user to slide the actuating element using the sliding section. It is also conceivable that there is a combined slide-handle actuation, so that the user can choose between the slide actuation or the handle actuation, depending on the application.

In the case of a sliding actuation, the actuation section for displacing the actuation element can be mounted on the outside of the insulating material housing, so that it is easily accessible to the user from the outside. This is moved on the insulating housing during actuation and is easily accessible even when the clamping point is open. When the handle is actuated, on the other hand, the actuating element is inside of the insulating material housing, wherein the actuating element can only be accessible to the user from the outside via a smaller pressure surface than the sliding section. Furthermore, when the clamping point is open, the actuating element of the handle actuation is mounted within the insulating housing, so that access for the user is difficult and an additional actuating tool may be required to loosen the actuating element.

The indefinite term "a" is to be understood as such and not as a numeral. So it is also conceivable that the conductor terminal is designed as a multi-pole conductor terminal with multiple clamping points. For example, it is conceivable that the conductor terminal is a two-pole, three-pole or six-pole conductor terminal. Correspondingly, the conductor connection terminal has two, three or six clamping points, which are formed from one or more busbars and one or more clamping springs.

The invention is explained in more detail below using exemplary embodiments with the accompanying drawings. Show it:

1 shows a conductor terminal 1 in a first embodiment in a lateral sectional view. The conductor connection terminal 1 has an insulating material housing 2 with a conductor insertion opening 3, it being possible for an electrical conductor to be inserted into the conductor connection terminal 1 in a conductor insertion direction L. A busbar 4 and a clamping spring 5 are arranged in the insulating material housing 2 . The clamping spring 5 has a contact leg 5a, which merges into a spring arc 5b and then extends into a clamping leg 5c. The clamping leg 5c and the conductor rail 4 form a clamping point 6 for the electrical conductor to be clamped.

It can be seen that the conductor terminal 1 has an actuating element 7 , the actuating element 7 being mounted in the insulating material housing 2 in a displaceable manner. The actuating element 7 has an actuating section 7a, the actuating section 7a interacting with the clamping leg 5c in such a way that the actuating section 7a rests against the clamping leg 5c in order to open the clamping point 6. The actuating element 7 is mounted in the insulating housing 2 essentially parallel to the conductor insertion direction L, with the actuating element 7 being set up for actuation in an actuating direction B, parallel to the conductor insertion direction L, for opening the terminal point 6 . In the 1 the clamping point 6 is completely closed, so that no electrical conductor can be inserted through the conductor insertion opening 3.

To release the actuating element 7 from the open position, the actuating element 7 can be pushed manually in the release direction R on the actuating section. As a result, the clamping point is closed again, i.e. the clamping leg 5c is no longer deflected by the actuating element 7.

As can be seen, the actuating element 7 is supported on the insulating material housing 2 with a sliding section 7e in the interior of the insulating material housing 2 . During a displacement movement, the displacement section 7e slides along this area of the insulating material housing 2 .

The actuating section 7d can be supported on the outside of the insulating material housing 2 and can slide along this area of the insulating material housing 2 during a displacement movement.

A conductor guide bevel 20 can also be seen in the upper region of the conductor insertion opening 3 in the vicinity of the actuating section 7a.

2 shows an actuating element 7 in a perspective view and 3 shows the button element 7 after 2 in a side sectional view. The actuating element 7 is for use in a conductor terminal 1 after 1 educated.

It can be seen that the actuating element 7 has a pressure section 7b, the pressure section 7b being the section for displacing the actuating element 7 in the actuation direction B by exerting a force on the pressure section 7b. Two side elements 7c lying opposite one another and spaced apart from one another protrude from the pressure section 7b. The side elements 7c are preferably aligned parallel to one another, with a space being formed between the side elements 7c. The actuation section 7a for opening the clamping point 6 is arranged on the ends of the side elements 7c opposite the pressure section 7b.

It is clear that the actuating element 7, in particular the side elements 7c, form an opening 8. This opening 8 is surrounded by the pressure section 7b, the side elements 7c and the actuating section 7a.

It is also clear that the actuating element is designed as a slide-push button actuation. The actuating element 7 has an actuating section 7d, the actuating section 7d being supported on the outside of the insulating material housing 2 and being set up for manual actuation of the actuating element 7. Alternatively, the actuating element 7 can also be actuated via a compressive force on a compressive section 7b.

It can be seen that the sliding section 7e is arranged on the side of the operating element 7 facing away from the operating section 7d.

Out 1 it becomes clear that a projection 9 of the insulating material housing is accommodated through the opening 8 of the actuating element 7 . The projection 9 protrudes through the opening 8 and is surrounded by the pressure section 7b, the side elements 7c and the actuating section 7a, with the actuating element 7 thus being mounted in the conductor terminal 1 in a displaceable manner so that it cannot be lost.

It is also clear that the actuating section 7a of the actuating element 7 is slidably mounted on a latching contour 10 of the insulating material housing 2 designed as an elongate guide rail. The actuation section 7a is guided on the latching contour 10 during the displacement of the actuation element 7 in the actuation direction B. The parallel configuration of the conductor insertion direction L and the actuation direction B can prevent the actuation section 7a from getting into the area of the clamping point 6 and/or into the area into which the electrical conductor is inserted and thus blocking or blocking the insertion of the electrical conductor damaged an inserted electrical conductor.

From the 1 until 3 it can be seen that a pin 11 is arranged on the actuating element 7 . The peg 11 protrudes from the pressure section 7b in the conductor insertion direction L from the actuating element 7, the peg 11 being slidably receivable in a recess 12 of the insulating material housing 2. The recess 12 is arranged on the projection 9 of the insulating material. If the actuating element 7 is displaced in the actuating direction B, the actuating element 7 is guided essentially linearly by the spatial limitation of the pin 11 and the recess 12 in order to open the clamping point 6 .

4 and 5b each show a conductor terminal 1 1 with open terminal point 6, wherein the conductor terminal 1 of 4 and 5b each shown in a different sectional view. the 5a shows the conductor terminal 1 in the same sectional view as the 5b , where in the 5a the actuating element 7 is shifted from an initial position to an intermediate position in which the clamping point is not yet open. In the 5b the actuating element 7 is pushed further into the actuating position in which the clamping point is open.

It is clear that the operating section 7a during the operating process, i.e. during the displacement of the operating element 7 from a starting position in the operating direction B via an intermediate position, which is in 5a is shown, in a in 5b Actuation position shown, in which the terminal point 6 is open, rests on the locking contour 10 and the clamping leg 5c is displaced in such a way that the terminal point 6 is opened. The actuating section 7a is arranged between the clamping leg 5c of the clamping spring 5 and the latching contour 10 . The actuating section 7a is in a latching position between the clamping leg 5c of the clamping spring 5 and the latching contour 10, the actuating section 7a being pressed by the spring force of the clamping leg 5c against the latching contour 10 and thus being held on the latching contour 10.

It can be seen that the actuating element 7 is mounted in such a way that the actuating element 7 is mounted such that it can be tilted about a bearing point 13 on the insulating material housing 2 into the locking position. Once the actuator 7 in the actuator position is transferred, the actuating element 7 tilts about the support point 13 on the insulating material housing 2, the actuating element 7, in particular the actuating section 7a being held in the latching position by the spring force of the clamping leg 5c on the latching contour 10. It is conceivable that the bearing point 13 is designed as a bearing area, with the actuating element 7 being designed to be tiltable about this bearing area.

When shifting into the operating position, the operating section 7a moves into a recess in the latching contour 10 . As a result, the actuating section 7a is arranged at approximately the same height as the end of the conductor insertion channel and thereby closes the free space and in this way prevents an electrical conductor, in particular a stranded conductor, from getting caught when it is inserted into the terminal point 6. The actuating section 7a can be shaped or be designed with respect to its contour that the same conductor insertion bevel as in the conductor insertion channel is present through the actuating section 7a. As a result, inserted electrical conductors are deflected in the conductor connection direction and are thus passed under the operating section 7a.

It is also clear that the pin 11 is guided in the recess 12 during the actuation process. One recognizes in particular in the 4 that the pin 11 is arranged largely or completely within the recess 12. The parts are held together in a form-fitting manner against the spring force of the clamping spring 5 , particularly in the case of a two-part design of the insulating material housing 2 . This supports an existing latching of these housing parts.

It can be seen that the pin 11 enters into a form-fitting connection with the recess 12 . As a result, the actuating element 7 also holds the housing parts of the insulating housing 2, in particular the cover and main housing part, together and supports a latching formed between these housing parts.

It can be seen that in the actuated position of the actuating element 7, when the clamping leg 5c is deflected by the actuating section 7a, a free space 21 has formed between the actuating section 7a and the conductor guide bevel 20. The sloping conductor guide 20 is used to guide the electrical conductor to the terminal point, i.e. to center the inserted electrical conductor. The side of the actuating section 7a that faces the free space 21 can be designed and slanted in a manner comparable to the slanted conductor guide 20. In this way, the inserted electrical conductor is still guided in the same way by the corresponding slanted surface on the actuating section 7a even after it has passed the slanted conductor guide 20 deflected and led to the clamping point. In this way, the electrical conductor is guided along under the operating section 7a.

Is recognizable in the 5a and 5b also a restoring spring element 17, which acts on the actuating element 7 and exerts a compressive force on it. The actuating element 7 is moved back into the starting position by the return spring element 17 when the latching of the actuating section 7a with the latching contour 10 is overcome manually.

6 shows a contact insert made of a clamping spring 5 and a busbar 4 in a lateral sectional view, with the clamping spring 5 and the busbar 4 forming a clamping point 6 for an electrical conductor to be clamped. The contact insert is for use in a conductor terminal 1 according to 1 , 4 and 5 educated.

The clamping spring 5 has a contact leg 5a, which merges into a spring bow 5b, the spring bow 5b extending into a clamping leg 5c to form the clamping point 6 with the busbar 4.

It can be seen that at the free end of the contact leg 5a a first holding element 14a and a second holding element 14b are exposed in a direction pointing away from the clamping leg 5c of the clamping spring 5 from the contact leg 5a. The first holding element 14a is mounted on a first holding edge 15a and the second holding element 14b on a second holding edge 15b. The holding edges 15a, 15b are arranged on the conductor rail 4.

It becomes clear that the first holding element 14a encompasses the first holding edge 15a. The second holding element 14b, which is spaced apart from the first holding element 15a, is arranged in the direction of the spring bow 5b, with the second holding element 14b reaching through the second holding edge 15b, which is designed as the edge of a holding opening. The first holding element 14a is arranged at the free end of the contact leg 5a, the second holding element 14b being arranged at a distance from the first holding element 14a in the direction of the spring bow 5b. A conductor rail section 16 of the conductor rail 4 overlaps the contact leg 5a or is supported on the contact leg 5a. In this way, a stable connection of the clamping spring 5 to the busbar 4 and at the same time a high degree of mobility of the clamping spring 5 can be ensured.

the 7 and 8th show a further advantageous embodiment of a contact insert of a conductor terminal 1. The contact insert has a busbar 4 and a clamping spring 5. In this case, the clamping spring 5 is designed for clamping two electrical conductors. It therefore has two side-by-side arrangements of contact leg 5a, spring bow 5b and clamping leg 5c. The busbar 4 is designed to be correspondingly wide, so that the free ends of both clamping legs 5c rest against the busbar 4 in the area of the clamping point 6 when no electrical conductor is clamped there. A separate electrical conductor can thus be clamped to the conductor rail 4 in the area of the clamping point 6 by each clamping leg 5c.

The contact legs 5a merge into a common material area, which protrudes through a recess in the busbar 4 and on the underside of the busbar 4, i.e. on the side of the busbar 4 facing away from the clamping point 6, has a holding section 5d of the clamping spring 5, through which the clamping spring 5 are attached to the conductor rail 4.

A restoring spring element 17 can be present between the two contact legs 5a. The restoring spring element 17 can be formed in one piece with the clamping spring 5, e.g. as a stamped and bent component. The return spring element 17 is used for the spring-assisted return of the actuating element 7 from an actuating position to the starting position.

the 9 shows a conductor terminal in a plan view of the actuating side, ie that side of the insulating housing 2 on which the actuating sections 7d of the actuating elements 7, which serve as a manual actuating area of the respective actuating element 7, are accessible. It can be seen that the top three actuating elements 7 are in their initial position, while the lowermost actuating element 7 has been moved into the actuating position in which the clamping point is open. Advantageously, with such a slide actuation of the clamping point, a status display with regard to the open state of the clamping point can be implemented with little effort, for example by applying a corresponding inscription 18 “open”/“closed” or suitable graphic symbols to the insulating housing 2 . By these symbols being attached to respective opposite ends of the displacement range of the operating element 7, one of these symbols is alternately covered and the other released, depending on the operating state of the operating element 7. In this way, the user can easily identify the state in which the terminal point of a respective conductor connection area of the conductor connection terminal 1 is located.

the 10 shows an embodiment of a conductor terminal 1, in which a restoring spring element 19 for restoring the actuating element 7 to the starting position is not formed on the clamping spring 5, but is present as a separate element. For example, the restoring spring element 19 can be arranged in the recess 12 of the insulating material housing 2 and can extend beyond the pin 11 of the actuating element 7 . The restoring spring element 19 can be designed, for example, as a spiral spring. The restoring spring element 19 is supported on one side on the bottom of the recess 12 and on the other side in the peripheral area of the pin 11. The restoring spring element 19 then acts directly on the pressure section 7b of the actuating element 7.
