Description

The invention relates to a conductor connection terminal with an insulating material housing, the insulating material housing having a terminal housing as well as an actuating housing mounted displaceably relative to the terminal housing, at least one busbar piece and at least one clamping spring for forming at least one clamping point for an electrical conductor to be clamped being arranged in the terminal housing and that The actuating housing has an actuating section which is designed to interact with the clamping spring for opening and / or closing the clamping point, and wherein a conductor entry opening is formed with a conductor entry channel adjoining the conductor entry opening for guiding the electrical conductor to be clamped to the clamping point.

DE 81 37 917 U1 shows a screwless connection terminal for an electrical conductor with a hollow cylinder-shaped housing, into which the conductor can be inserted axially through the upper end face and can be clamped to two diametrically arranged legs of a clamping spring. A cap element is provided that partially coaxially surrounds the housing and acts on the two legs with a section for opening the clamping spring.

Likewise, in DE 10 2009 008 933 A1 an electrical connection terminal with a terminal housing and a box-shaped actuating element described which is slidably mounted in the terminal housing. The actuating element has an inner contour which is designed to move the clamping leg against the spring force.

US 2011/0207372 A1 discloses a conductor connection terminal with a two-part insulating material housing, a clamping spring and a busbar piece. The parts of the insulating material housing can be displaced relative to one another, and the clamping point can be opened by moving the parts of the insulating material housing.

Based on this, the object of the present invention is to create an improved conductor connection terminal.

The object is achieved with a conductor connection terminal with the features of claims 1, 4 and 5. Advantageous embodiments are described in the subclaims.

In the case of the generic conductor connection terminal, it is proposed that the conductor entry opening, together with the conductor entry channel, be arranged stationary relative to the busbar section in the terminal housing or on the terminal housing and that the actuating housing at least partially surrounds a housing section having the conductor entry opening and the conductor entry channel and is mounted on this housing section so as to be displaceable relative thereto.

A compact conductor connection terminal with an integrated actuation mechanism is provided in that the actuation housing is arranged displaceably in or on the terminal housing. By shifting the thus multi-part insulating material housing, the actuating housing causes, for example, an opening of the clamping point through its force action with a clamping spring counter to the spring force. The actuating housing has an actuating section which, when the actuating housing is displaced relative to the terminal housing and the clamping spring arranged therein, e.g. the clamping point opens by the actuation section engaging with its contour with the clamping spring, displacing the clamping leg against the spring force and thus releasing the clamping point for the electrical conductor to be clamped. The insulating material housing thus serves at the same time as an actuating element which takes on a housing function that partially covers the interior of the conductor connection terminal and an actuating function for opening and / or closing the terminal point. A separate special operating lever or operating lever is not required.

The insulating material housing is formed in several parts by the terminal housing and the actuating housing, the several parts being mounted so as to be displaceable relative to one another.

The conductor entry opening and the conductor entry channel adjoining it can be arranged in a stationary manner relative to the conductor rail section in the terminal housing or on the terminal housing. The actuating housing surrounds a housing section having the conductor insertion opening and the conductor insertion channel and is mounted on this housing section so as to be movable relative thereto.

In this way, the actuating housing can surround the housing section having the conductor insertion opening and the conductor insertion channel in the manner of a sleeve and can be displaceably guided on this section. The actuating housing can thus be displaced in the manner of a sleeve with respect to the housing section which has the stationary conductor insertion opening and the conductor insertion channel adjoining it. During actuation by shifting the actuation housing, the conductor entry opening and the conductor entry channel connected to it remain with its inner wall stationary to the inserted electrical conductor. The position of the electrical conductor in relation to the terminal point is therefore not influenced by the actuation. This prevents the electrical conductor from sliding back out of its end position. This ensures sufficient contact overlap of the stripped end of the electrical conductor at the terminal point.

The conductor connection terminal can be designed in such a way that the housing section, which has the conductor entry opening and the conductor entry channel, is arranged within the outer contour of the actuating housing when the terminal point is closed, in which the actuating housing is displaced relative to the terminal housing in such a way that the actuating section does not deflect the clamping spring is, ie does not protrude from the outer contour. The housing section having the conductor entry opening and the conductor entry channel, however, protrudes from the actuating housing when the terminal point is open, in which the actuating housing is displaced relative to the terminal housing so that the actuating housing deflects the clamping spring. This ensures that there is no point of contact between the electrical conductor and the actuation housing when actuated by moving the actuation housing. The position of the electrical conductor remains unaffected by the actuation.

The housing section having the conductor insertion opening and the conductor insertion channel can be an integral part of the terminal housing. The conductor entry opening and the conductor entry channel adjoining it are thus introduced into the terminal housing. The housing section can, however, also be designed as a separate conductor guide part which is connected to the terminal housing. This connection can be, for example, form-fitting, frictional-fitting or force-fitting. The conductor entry part can be connected to the terminal housing e.g. be glued, welded, screwed, riveted or latched.

The conductor insertion opening and the conductor insertion channel adjoining it can, however, also be formed integrally with the terminal housing as part of the latter.

The conductor connection terminal can have two clamping points for two electrical conductors to be clamped independently of one another on two clamping legs of the clamping spring or on two clamping springs. Correspondingly, two conductor entry openings with each adjoining conductor entry channels for guiding the electrical conductors to be clamped to a respective clamping point are formed. The actuation housing can surround the housing section having the two conductor insertion openings and the conductor insertion channels.

The object is also achieved by a conductor connection terminal with an insulating material housing, which has a terminal housing and an actuating housing that is mounted displaceably relative to the terminal housing. A busbar piece and a clamping spring with two clamping legs or two clamping springs are arranged in the terminal housing to form two clamping points for two electrical conductors to be clamped independently of one another to a respective clamping point. Two conductor entry openings are designed to guide the electrical conductors to be clamped to a respective clamping point. The actuation housing has two actuation parts which are mounted relatively displaceably relative to one another and which each have an actuation section for opening and / or closing a respective clamping point.

With these two actuating parts, which can be moved independently of one another, it is possible to open or close the terminal points for the two electrical conductors independently of one another. In this way, an electrical conductor can be clamped on or removed from the other electrical conductor without impairing the clamping effect and the contact resistance. The conductor connection terminal can be very compact and easy to use.

The object is also achieved by a conductor connection terminal with an insulating material housing, which likewise has a terminal housing and an actuating housing mounted so as to be displaceable relative to the terminal housing. A busbar piece and a clamping spring are arranged in the terminal housing to form a clamping point for an electrical conductor to be clamped. The actuation housing has an actuation section which is designed to cooperate with the clamping spring for opening and / or closing the clamping point. A conductor entry opening is designed to guide the electrical conductor to be clamped towards the clamping point.

The clamping spring has an actuating tab which protrudes laterally from the clamping leg of the clamping spring formed between a clamping edge for clamping the electrical conductor and a spring arch of the clamping spring. The actuating section is arranged laterally next to the alignment of the assigned conductor insertion opening or the conductor insertion channel adjoining it and next to the clamping leg. The actuating tab of the clamping spring and the actuating section of the actuating housing are aligned cooperatively to open and / or close the clamping point.

In this way, the actuating housing can be made very compact in order to equally fulfill its function as a housing part that partially delimits the insulating material housing and as an actuating element. The actuating housing does not act on the clamping leg, that is to say the clamping section of the clamping spring located between the clamping edge and the spring arch, but laterally offset to it. The actuation section of the actuation housing is offset to the side next to the alignment of the conductor entry opening. It is spaced apart in the conductor insertion direction, ie in the longitudinal direction of the associated conductor insertion channel, from the opening of the conductor insertion channel. Thus, a housing section delimiting the conductor entry channel does not act on the clamping leg, but a separate actuating section arranged at a distance from this housing section. This actuation section can be designed as a projection protruding perpendicular to the alignment of the conductor insertion opening.

The actuating mechanism is thus shifted for opening and / or closing the clamping point outside the axis between the clamping edge and the spring arch. The actuation section can thus be arranged laterally next to that of the conductor insertion opening and an adjoining conductor insertion channel. It can thus be prevented that the actuating section does not damage the clamped-on electrical conductor or unintentionally pull it out when the actuating housing and the terminal housing are moved relative to one another.

For further improvement, the busbar piece can have a recess through which the actuating section of the clamping spring protrudes so that the actuating mechanism is spatially separated from the clamping point. The actuating tab then protrudes through the recess. The actuating tab and the actuating section can thus be accommodated in the insulating material housing in a space-optimized manner. The actuation section can thus be guided laterally next to the clamping point, at the same time preventing the actuation section from coming into contact with the electrical conductor to be clamped.

This recess can also be used to guide the actuating section in the recess in a displaceable manner.

In a variant of a conductor connection terminal, the conductor entry opening and the conductor entry channel adjoining it can be formed integrally with the actuating housing as part of the latter.

As a result of this fixed arrangement, a displacement of the multi-part insulating material housing (terminal housing and actuating housing) relative to one another also causes a displacement of the conductor entry opening and the conductor entry channel connected to it relative to the terminal housing. It is thus possible for the conductor entry opening and possibly also a part of the conductor entry channel to be arranged within the outer contour of the insulating material housing when the terminal point is closed. To open the terminal point, the conductor entry opening is pushed out of the outer contour of the insulating material housing. This signals to the user that the terminal point is open and the electrical conductor to be clamped can be inserted. In the opposite case, an invisible conductor entry opening signals that the terminal point is closed.

The conductor connection terminal can have a signal element, the signal element being arranged within the insulating material housing when the terminal point is closed and the signal element protruding from the insulating material housing when the terminal point is open. For several terminal points, a one-piece signal element can have several ends formed in one piece with the signal element corresponding to the number of terminal points, e.g. in the open state protrude from the insulating housing. The signal element can, however, also be in several parts, depending on the number of terminal points, with several separately displaceable parts and a respective end protruding from the insulating material housing in the signal state. For example, the signal element can be in two parts with two separately displaceable parts and a respective end that can be pushed out of the insulating material housing.

The signal element signals the state (open / closed) of the terminal point to the user. The signal element can be a displaceable signal element arranged on the insulating material housing, shifting the multi-part insulating material housing (terminal housing and actuating housing) also leading to a displacement of the signal element or one end of the signal element out of the insulating material housing.

The conductor connection terminal can have a restoring element, the restoring element exerting a restoring force on the terminal housing and / or on the actuating housing in the open state of the clamping point. It is also advantageous if the reset element is a spring element.

Due to the resetting element, the multi-part insulating material housing (housing part and housing section) does not have to be closed manually Position of the clamping point are brought. The restoring force of the spring causes the housing section and the housing part to be returned to their initial position (rest position). A spring, for example, can be used as a return element.

The actuating housing can be slidably mounted in the terminal housing or on the outer wall of the terminal housing. As a result, an even more compact conductor connection terminal can be provided. The terminal housing is thus designed like a sleeve and can at least partially accommodate the actuating housing. In particular, the actuation housing can be pushed almost completely into the terminal housing. Under almost complete is to be understood in particular that only the rear wall of the actuating housing remains visible to the outside. A sleeve-like actuating housing can, for example, be slid over the outer wall of the terminal housing.

The embodiments of conductor connection terminals described above can have a second clamping spring for forming a second clamping point for a second electrical conductor to be clamped and a second conductor insertion opening which is designed to guide a second electrical conductor to be clamped towards the second clamping point.

The clamping springs can, for example, have a contact leg, a spring bow and a clamping leg. You can e.g. be designed as a U-shaped bent leg spring. A clamping edge at the free end of the clamping leg can, together with a clamping edge on the busbar piece, form a defined clamping point for an electrical conductor to be clamped.

A conductor connection terminal can thus be provided in which two terminal points for electrical conductors to be clamped can be opened and / or closed simultaneously by the relative displacement of the actuating housing and the terminal housing. A two-part construction of the actuating housing makes it possible to actuate the two clamping points independently of one another with a compact, simple design. Then the insulating housing is made up of three parts.

It is optionally conceivable for the insulating material housing to have more than two terminal points and thus more than two conductor entry openings with each adjoining conductor entry channels. The actuation housing is then for the simultaneous actuation of all clamping legs, i. designed to open or close all terminal points simultaneously, or in the case of a multi-part construction of the actuating housing for separate actuation of the clamping legs.

The above statements on the conductor connection terminal with only one terminal point can be applied accordingly to all corresponding elements of a conductor connection terminal with several terminal points.

The indefinite term “a” is to be understood as such and not as a numerical word. The conductor connection terminal according to the invention is not limited to the number of individual elements. For example, it is conceivable that the conductor connection terminal according to the invention has a plurality of clamping springs, conductor entry openings with conductor entry channels connected to them, actuating parts and / or actuating housings.

1 shows a conductor connection terminal 1 in a first embodiment, with an insulating housing 2 . The insulated housing 2 is constructed in two parts and has a terminal housing 3 and an actuator housing 4th . It can also be seen that the conductor connection terminal 1 an electric conductive busbar piece 5 , a first clamping spring 6a and a second clamp spring 6b Has. The first clamp spring 6a and the second clamp spring 6b each have a contact leg 7a , 7b , a feather bow 8a , 8b and a clamp leg 9a , 9b . The clamp leg 9a the first clamp spring 6a and the clamp leg 9b the second clamping spring 6b each form a clamping point with the busbar piece 5 for connecting one electrical conductor each. On the actuator housing 4th are two conductor entry openings 10a , 10b with each adjoining conductor entry channels 18a , 18b arranged. The first conductor entry opening 10a has an adjoining conductor entry channel 18a , which is designed so that it leads an electrical conductor to be clamped to the first clamping point. The second conductor entry opening 10b has an adjoining conductor entry channel 18b , which is designed so that it leads a second electrical conductor to be clamped to the second clamping point.

Inside the insulating housing 2 are on the actuator housing 4th a first operating section 11a and a second operating section 11b arranged. The operating sections 11a , 11b are from the inner wall plane of the actuation housing 4th into the interior of the insulating housing 2 protruding projections with an inclined surface formed by a wedge-shaped cross-section. The first operating section 11a is set up to open the first clamping point and the second actuation section 11b is set up to open the second terminal point. The operating sections 11a , 11b are designed, for example, as an actuation contour that extends into the space of the insulating material housing 2 protrude.

The 1 shows the conductor connection terminal 1 in a state in which the clamping points are closed, whereas 2 the conductor connection terminal 1 out 1 shows in a state in which the clamping points are open. In the closed state of the clamping points, the clamping edges are at the free end of the clamping legs 9a , 9b in the direction of the respective contact surface of the busbar piece 5 by the spring force of the clamping spring 6a , 6b deflected. The clamp legs are in the open state 9a , 9b in the direction of the respective contact leg 7a , 7b the clamp springs 6a , 6b against the spring force of the clamping springs 6a , 6b pushed back.

It can be seen that the terminal housing 3 and the actuator housing 4th of the two-part insulating housing 2 are mounted displaceably against each other. Will the terminal box 3 and the actuator housing 4th shifted relative to one another, the actuating sections arrive 11a , 11b in engagement with the clamping legs 9a , 9b or with one of these clamping legs 9a , 9b protruding actuation tabs of the respective clamping springs 6a , 6b whereby the first clamping point and the second clamping point are opened.

It is also clear that the terminal housing 3 in the actuator housing 4th to the extent that it is recorded that only the back of the actuating housing 4th remains visible to the outside. The actuator housing 4th is thus designed like a sleeve, the actuating housing 4th when moving over the terminal housing 3 to be led.

The busbar piece 5 has two recesses 12a , 12b , with an actuating tab (not shown in the sectional view) of the clamping springs 6a , 6b into the recess 12a , 12b protrudes. The operating sections 11a , 11b interact with the actuating tabs. The operating sections 11a , 11b provide an operating mechanism with the respective operating tabs to open the clamping points.

It becomes clear that thereby the actuating mechanism for opening the clamping points outside the axes between the clamping edges and the spring arches 8a , 8b is relocated. The operating sections 11a , 11b can thus laterally next to the alignment of the conductor entry openings 10a , 10b , ie in the alignment of an adjoining conductor entry channel 18a , 18b be arranged. The actuation mechanism of the clamping springs 6a , 6b is thus spatially separated from the clamping point and from the spring bow 8a , 8b , clamping legs extending up to the clamping edge 9a , 9b . The operating sections 11a , 11b can thus be guided laterally next to the clamping points, which at the same time precludes the actuation sections 11a , 11b undesirably come into contact with the respective electrical conductor to be clamped.

It is also clear that both clamping points are opened at the same time. Opening only one clamping point while the other clamping point is closed is not possible in this exemplary embodiment.

3 shows a conductor connection terminal 1 in a second embodiment. The second embodiment is basically similar to that in FIGS 1 and 2 first embodiment shown. In addition, the conductor connection terminal provides 1 according to the second embodiment, a signal element 13 ready. The signal element 13 can be in two parts with two separately movable parts 13a , 13b and a respective end 15a , 15b (in 4th recognizable) or in one piece with two ends 15a , 15b be that from the insulating housing 2 can be pushed out. Immediately in front of the clamping spring there can be an oblique to the conductor insertion direction or the alignment of the conductor insertion channel 18a , 18b running guide wall of the respective conductor entry channel 18a , 18b be present, which are designed to guide the electrical conductor onto the clamping leg.

3 shows the conductor connection terminal 1 in a state in which the clamping points are closed, whereas 4th the conductor connection terminal 1 out 3 shows in a state in which the clamping points are open.

It becomes clear that when the actuation housing is moved 4th relative to the terminal housing 3 the actuation housing 4th relative to the stationary to the terminal housing 3 stored signal element 13 shifts such that the signal element 13 with its ends 15a , 15b from the insulating housing 2 protrudes. So the ends are there 15a , 15b of the signal element 13 from the insulating housing 2 out when the terminal points are open. The user is thus informed by the signal element 13 indicates when the electrical conductors to be clamped can be inserted into the conductor connection terminal.

It can also be seen that in each case a wall section of the conductor entry channels 18a , 18b between the respective conductor entry channel 18a , 18b and the signal element 13 , 13a , 13b is available.

5 shows a conductor connection terminal 1 with the terminal point open in the second embodiment according to FIG 3 to 4th in a perspective view. It becomes clear that there are two ends 15a , 15b of the signal element 13 next to a conductor entry opening 10a , 10b from the insulating housing 2 stick out. The user can thus clearly see when a corresponding electrical conductor to be clamped into the conductor entry openings 10a , 10b can be introduced.

6th shows a third embodiment of a conductor connection terminal 1 . The third embodiment is basically similar to that in FIGS 1 to 2 first embodiment shown. The difference from the first embodiment is that in the third embodiment, the conductor insertion openings 10a , 10b stationary to the busbar piece 5 and the terminal housing 3 are executed. The actuator housing 4th is relative to the conductor entry openings 10a , 10b movably mounted. It surrounds the conductor entry openings 10a , 10b forming housing sections 16a , 16b in the manner of a sleeve and is slidable on the outer walls of these housing sections 16a , 16b stored.

It can be seen that the conductor entry openings 10a , 10b as well as the adjoining conductor entry channels 18a , 18b , the busbar piece 5 and the terminal housing 3 form a functional unit that is relatively slidable overall to the actuator housing 4th is trained.

While the 6th the conductor connection terminal 1 shows in a state in which the clamping points are closed, provides 7th this conductor connection terminal 1 out 6th in a state in which the terminal points are open.

It becomes clear that the fixed arrangement of the conductor entry openings 10a , 10b and the adjoining conductor entry channels 18a , 18b based on the busbar piece 5 and the terminal housing 3 for an exposure of the conductor entry openings 10a , 10b and the conductor entry channels connected to it 18a , 18b having housing sections 16a , 16b from the outer contour of the actuator housing 4th also leads as soon as the actuator housing 4th and to the back of the terminal housing 3 is moved towards to open the terminal points. The conductor entry openings 10a , 10b are thus from the movably mounted actuation housing 4th removed when the terminal points are open. Electrical conductors inserted into the conductor entry openings 10a , 10b are plugged in, touch the actuator housing 4th not and therefore not when the actuating housing is moved 4th influenced in their location.

With this release, the user can also see whether the terminal points are open. It is nevertheless conceivable that additional signal elements on the conductor connection terminal 1 are arranged to reinforce this effect.

8th shows the third embodiment of the conductor connection terminal 1 with open terminal point according to 6th to 7th in a perspective view. It becomes clear that the conductor entry openings 10a , 10b and, if applicable, part of the conductor entry channels connected to it 18a , 18b from the outer contour of the insulating housing 2 , ie from the front of the actuating housing 4th stick out. The user can thus clearly see when a corresponding electrical conductor to be clamped into the conductor entry openings 10a , 10b can be introduced. A touch of an inserted conductor by the sliding actuator housing 4th is prevented by this exemption.

9 shows a fourth embodiment of the conductor connection terminal 1 in a sectional view. The conductor connection terminal 1 has an insulating housing 2 , the insulating housing 2 a terminal housing 3 and a two-part actuator housing 4th Has. The actuation housing has a first actuation part 17a and a second operating part 17b on. It is thus clear that the insulating housing 2 is constructed in three parts.

It can also be seen that the conductor connection terminal 1 a busbar piece 5 , a first clamping spring 6a and a second clamp spring 6b Has. The first clamp spring 6a and the second clamp spring 6b each have a contact leg 7a , 7b , a feather bow 8a , 8b and a clamp leg 9a , 9b . The clamp leg 9a the first clamp spring 6a and the clamp leg 9b the second clamping spring 6b each form a clamping point with a respective side wall of the busbar section 5 To each have an electrical conductor between a clamping edge of the clamping leg 9a , 9b and to clamp a side wall. On the first actuation part 17a of the actuation housing 4th is a first conductor entry opening 10a and on the second operating part 17b of the actuation housing 4th a second conductor entry opening 10b arranged. The first conductor entry opening 10a goes into a ladder entry channel 18a over to lead a first electrical conductor to the first terminal point. The second conductor entry opening 10b also goes into one in line with the conductor entry opening 10b extending conductor entry channel 18b about to lead the second electrical conductor to the second terminal point and to clamp it there.

Inside the insulating housing 2 are on the first actuation part 17a a first operating section 11a and on the second operating part 17b a second operating section 11b arranged. The first actuation part 17a with its first operating section 17a is set up to open the first terminal point. The second actuation part 17b with its second operating section 11b is set up for this purpose independently of the first actuating part 17a to open the second terminal point. The operating sections 11a , 11b are designed as actuation contours that are in the space of the insulating housing 2 protrude.

9 shows the conductor connection terminal 1 in a state in which the clamping points are closed, whereas 10 the conductor connection terminal 1 out 9 shows in a state in which one clamping point is open and the other clamping point is closed.

It becomes clear that the actuator housing 4th and the terminal housing 3 are each mounted displaceably relative to one another. Both the first actuation part 17a , as well as the second actuating part 17b relative to the terminal housing 3 be moved separately from each other without the respective other actuating part 17a , 17b is moved with. The actuating parts 17a , 17b can have guide webs (eg cross-sectionally L-shaped webs or dovetail guides and the like) around the two actuating parts 17a , 17b to be slidable to each other.

In 10 it can be seen that the second actuating part 17b to the back of the terminal housing 3 is shifted towards, wherein the second operating portion 11b in engagement with the second clamping leg 9b the second clamping spring 6b stands, whereby the second terminal point is opened. It is also clear that the first actuation part 17a from the back of the terminal housing 3 is shifted away so that the clamping point is closed. The two clamping points can thus be opened independently of one another by removing the respective actuating part 17a , 17b relative to the terminal housing 3 is moved.

It is also clear that the terminal housing 3 to a large extent in that from the first actuation part 17a and the second operating part 17b formed actuator housing 4th is recorded. The actuating parts 17a , 17b are designed like a sleeve. When moving, they become on the circumferential side wall of the terminal housing 3 be guided.

It is also conceivable that the terminal housing 3 Is formed in two parts. The insulated housing 2 would then consist of a total of four parts. One actuation part each 17a , 17b would then be slidable against part of the two-part terminal housing 3 stored in order to open one clamping point each.

Optionally, designs are also conceivable in which there are more than two clamping points, the actuating housing 4th either in one piece for the simultaneous opening or closing of all terminal points or adapted to the number of terminal points in several parts with more than two actuation parts.

The busbar piece 5 has two recesses 12a , 12b , with an actuating tab (not visible in the sectional view) of the clamping springs 6a , 6b in one recess each 10a , 10b protrudes into it. The operating sections 11a , 11b interact with the actuating tabs. The operating sections 11a , 11b provide an operating mechanism with the respective operating tabs to open the clamping points.

It becomes clear that thereby the actuating mechanism for opening the clamping points outside the axes between the clamping edges and the feather arches 8a , 8b , ie on the side of the clamping leg 9a , 9b is shifted away. The operating sections 11a , 11b can thus laterally next to the conductor entry openings 10a , 10b and the conductor entry channel formed thereby 18a , 18b be arranged. The operating sections 11a , 11b are removed from the opening of the conductor entry openings 10a , 10b arranged and protrude as projections in the direction of the alignment of the conductor entry channel 18a , 18b from a respective inner wall plane of the actuating housing 4th emerged. The actuation mechanism of the clamping springs 6a , 6b is thus positioned spatially separated from the terminal point. The operating sections 11a , 11b can thus be guided laterally next to the clamping points, which at the same time precludes the actuation sections 11a , 11b undesirably come into contact with the respective electrical conductor to be clamped.

The exemplary embodiments are not inextricably linked. A combination of the exemplary embodiments is possible. For example, it is conceivable that a conductor connection terminal according to the invention 1 with conductor entry openings 10a , 10b , which are stationary opposite the busbar piece 5 and / or the terminal housing 3 are formed and / or with a signal element 13 and / or a plurality of actuating parts 17a , 17b , which are mounted displaceably with respect to a housing section, is provided.
