Definitions
- the invention relates to a conductor connection terminal with an insulating material housing, where 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 forms, and with an actuating element, wherein the actuating element is slidably mounted in the insulating housing and for opening and / or closing the terminal point is rich switched.
- DE 102008 039 232 A1 discloses a conductor terminal with a busbar and a clamping spring, with 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.
- the actuating element has an opening for receiving a projection of the insulating material housing.
- a captive actuating element can be provided. Captive means that the actuating element cannot be removed from the conductor connection terminal without external influence.

- 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 projection of the insulating material housing can thus be cut in particular from the pressure section, the two opposite side elements and the actuating section can be enclosed, so that a simply constructed conductor connection terminal is provided, the actuating element being captively mounted on the insulating material housing so that it can be displaced.
- 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 is set up for manual actuation of the actuation element, the actuation section protruding from the pressure section in the conductor insertion direction.
- an outer wall of the insulating material housing can be accommodated between the actuating section and the side elements.
- the actuation portion may be oriented substantially perpendicular to the pressure portion.
- the actuation portion and/or the pressure portion may be oriented substantially perpendicular to the side members.
- a pin can be arranged on the actuating element, the pin being slidably received in a recess of the insulating material housing.

- the pin is accommodated at least to a substantial part in the recess, at least when the actuating element is fully actuated, when the clamping point is opened by the actuating element.
- a form-fitting coupling between various parts of the insulating material housing can be realized through the pin and the recess, for example between a main housing part and a cover part of the insulating material housing.
- the pin and the recess hold the housing-lid latch together at least when the actuating element is fully depressed.

- the pin can be arranged on the pressure section and the recess on the projection of the insulating material housing, the pin protruding from the actuating element in the conductor insertion direction.
- the actuating element and the insulating housing are held together during actuation.
- 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.
- the first housing part can be a main housing part
- the second housing part can be a cover part.
- the erfindungsge Permitted conductor terminal can be easily installed 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.
- 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 terminal point is open, in the recess from 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.
- the spring element is mounted within the recess.
- the Fe derelement is thus a spring element separate from the clamping spring, the Fe derelement enabling the actuating element to be reset from the actuating position in which the clamping point is open to 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 connection terminal thus has a spring element which is present in addition to the clamping leg of the clamping spring, with the actuating element being able to be guided back into the starting position via the spring element.
- the actuating element can extend essentially parallel to the conductor insertion direction.
- 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.
- the actuating element can be guided parallel to the conductor entry, so that the introduction of the electrical conductor cannot be blocked by the actuating element.

- the first holding element and the second holding element can be placed 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.
- 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.
- the first holding element engages behind the first holding edge on the busbar.
- the second retaining element which is spaced apart from the first retaining element, is arranged, which is supported on the second retaining edge of the busbar or, for example, penetrates one of the retaining 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.
- 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 an 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, the actuating element being mounted in a bearing point on the insulating material housing in such a way that the actuating element moves around the bearing point into a latching position or off the locking position can be tilted.
- a tilting movement takes place in particular as a rotation through a small angle of rotation.
- 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.
- a pivoting movement which is basically used in the case of operating levers, takes place around 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.
- no opening and/or closing of the clamping point results from the tilting movement according to the invention.
- the actuating element is transferred into a latching position by the tilting movement about the support point or is moved out of the latching position so that the actuating element can be held in an open position of the terminal point.
- the pivoting movement causes the clamping point to open or close.
- 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, the actuation element being displaceably mounted in the actuation channel.
- the actuating element can be tilted about this support point, so that the actuating element can be moved 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, the actuating element being held in the detent position by the spring force.
- the actuating element can be guided out of the locking position by an actuating tool, for example, by tilting it back around the support point.
- the actuating element can be designed as a sliding actuation, the sliding actuation having a sliding section which is supported at least in part with a bearing surface on the insulating material housing.
- a slide actuation provides an alternative actuation option to a push-button actuation, it being possible for the user to slide the actuation element by means of the sliding section. It is also conceivable that there is a combined slide-handle actuation, so that the user can choose between slide actuation or lever actuation, depending on the application.
- 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.
- the actuating element is guided inside the insulating housing, with the actuating element only having a smaller pressure surface than the sliding section of can be accessible to the user from the outside.
- the actuation element of the handle actuation is stored within the insulating material housing, so that access for the user is difficult and an additional actuation tool may be required to release the actuation element.
- the conductor connection terminal is designed as a multi-pole conductor connection terminal with several clamping points.
- the conductor terminal is a two-pole, three-pole or six-pole conductor terminal.
- 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 contact insert has a busbar 4 and a clamping spring 5.
- the clamping spring 5 is designed for clamping two electrical conductors. It therefore has two ne by each other running arrangements of contact leg 5a, spring arc 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 power rail 4 in the region 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 busbar 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, for example as a stamped and bent component.
- the return spring element 17 is used for spring-assisted return of the actuating element 7 from a supply position onds to the starting position.
- FIG. 9 shows a conductor connection terminal in a top view of the actuating side, ie that side of the insulating material housing 2 on which the actuating sections 7d of the actuating elements 7, which serve as the manual actuating area of the respective actuating element 7, are accessible.
- 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 .
- a corresponding inscription 18 “open”/“closed” or suitable graphic symbols to the insulating housing 2 .
- 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.
- FIG. 10 shows an embodiment of a conductor connection terminal 1 in which a restoring spring element 19 for restoring the actuating element 7 into the off initial position is not formed on the clamping spring 5 but is present as a separate element.
- the return spring element 19 can be arranged in the recess 12 from the insulating material housing 2 and extend up to the Zap fen 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 the bottom of the recess 12 on one side and in the peripheral area of the pin 11 on the other side.
- the restoring spring element 19 then acts directly on the pressure section 7b of the actuating element 7 .
