Definitions

  • the invention relates to a connection arrangement for connecting an electrical conductor.
  • the invention further relates to an electronic device.
  • connection arrangements usually have a clamping spring designed as a leg spring, which has a retaining leg and a clamping leg, wherein a conductor inserted into the connection arrangement can be clamped against a current bar by means of the clamping leg of the clamping spring.
  • the clamping spring must already be moved into an open position by means of the actuating element before the conductor is inserted and thus actuated in order to pivot the clamping spring or the clamping leg away from the current bar so that the conductor can enter the intermediate space forming the conductor connection space between the current bar and the clamping spring can be inserted.
  • the invention is therefore based on the object of making available a connection arrangement and a connection device in which the connection of, in particular, flexible conductors can be improved.
  • connection arrangement essentially has a housing, a conductor connection space formed in the housing, and a current bar which the conductor to be connected, inserted into the conductor connection space, can be clamped, a clamping spring which has a clamping limb which can be moved into a clamped position and an open position, an actuating element by means of which the clamping limb of the clamp spring can be moved from the clamped position into the open position, and a release element, wherein in the open position the actuating element is positioned such that the actuating element is latched to the housing in order to hold the clamping leg in the open position, the latching between the housing and the actuating element being releasable by means of the release element.
  • the clamping spring is preferably designed as a leg spring which has a holding leg and a clamping leg which is designed to be pivotable relative to the holding leg.
  • the holding leg is preferably arranged in a fixed position.
  • the clamping leg of the clamping spring By a pivoting movement of the clamping leg of the clamping spring, it can be moved into an open position in which the clamping leg is arranged at a distance from the current bar and a conductor to be connected can be inserted into or out of the conductor connection space in an intermediate space formed thereby between the current bar and the clamping leg, and in a clamping position, in which the clamping leg can rest on the current bar or on the connected conductor in order to clamp the conductor against the current bar, can be transferred.
  • the transfer of the clamping leg, in particular from the clamped position to the open position takes place by means of an actuating element.
  • the actuating element is preferably movably guided in a purely linear manner in the housing.
  • the actuating element preferably has an actuating section on which an actuating surface is formed, with which the actuating element bears against the clamping leg when the clamping leg is actuated.
  • the housing and the actuating element are designed in such a way that the actuating element forms a latch with the housing in the open position and thus latches on the housing.
  • the actuation element can be latched to the housing preferably in the area of the actuation section of the actuation element.
  • the latching can take place on an inner wall of the housing.
  • a release element is provided according to the invention for releasing this latching.
  • the actuating element can be moved freely again within the housing and by means of the spring force of the clamping leg of the clamping spring, the clamping leg can act on the actuating element in such a way that the clamping leg can pivot from the open position into the clamping position.
  • the release element preferably acts directly on the actuating element to cancel the latching.
  • the release element and the actuating element are thus preferably in an operative connection at least when the latching is released.
  • the release element is preferably a separately formed component which is arranged within the housing.
  • the release element enables easy handling of the release of the latching between the actuating element and the housing in order to convert the clamping leg of the clamping spring from the open position into the clamping position.
  • the release element can preferably be actuated in different ways.
  • the release element represents an auxiliary tool which can make it easier to connect flexible conductors, in particular.
  • the release element is preferably positioned in such a way that it is guided essentially parallel to the actuating element.
  • the direction of actuation of the actuation element is thus preferably aligned parallel to the direction of actuation of the release element.
  • the release element is preferably guided in a purely linear manner in the housing.
  • the release element can be designed in the form of a slide.
  • the release element is preferably arranged between the actuating element and the conductor connection space.
  • the release element can laterally delimit the conductor connection space at least in certain areas. Such an arrangement of the release element between the actuating element and the conductor connection space allows a particularly compact configuration of the arrangement.
  • the actuating element can be arranged between the release element and the clamping spring.
  • the release element can have an opening through which the clamping leg of the clamping spring can protrude.
  • the clamping leg can thus be guided into the conductor connection space via the opening on the release element.
  • the clamping leg can thus be passed through the release element.
  • the opening on the release element is preferably designed like a window, so that the opening is surrounded on all sides by the material of the release element.
  • the actuating element can have a latching edge which can interact with an undercut formed on the housing.
  • the undercut can be formed on an inner wall of the housing.
  • the latching edge of the actuating element can hook behind the undercut of the housing.
  • the latching edge is preferably formed on the actuating section of the actuating element.
  • the release element is preferably in direct contact with the actuating element, so that the release element can act directly on the actuating element.
  • the release element and the actuating element can preferably slide along one another.
  • the actuating element can have at least one guide bevel and the release element can have at least one guide bevel, with the at least one guide bevel of the release element being able to slide along the at least one guide bevel of the actuating element to release the latching.
  • the at least one guide bevel of the actuating element preferably has the same inclination as the at least one guide bevel of the release element.
  • the at least one guide bevel of the actuating element is preferably formed on the actuating section.
  • the actuating element preferably has two guide bevels formed parallel to one another. The latching edge of the actuating element can be formed between these two guide bevels of the actuating element. If the actuating element has two guide bevels, the release element preferably also has two guide bevels. The two guide bevels can prevent the actuating element and/or the release element from tilting when the locking mechanism is released. The two guide bevels of the release element can be arranged on the release element in such a way that the opening of the release element is formed between the two guide bevels. The two guiding bevels can limit the opening laterally.
  • the release element is preferably also arranged at a defined, fixed position relative to the actuating element.
  • a positive connection can be formed between the actuating element and the release element in the open position.
  • the release element can have at least one clearance for this purpose, into which the actuating element can be immersed in the open position.

  • the release element can have an actuating surface which can protrude into the conductor connection space and via which the release element can be actuated by means of the conductor to be connected.
  • the release element can protrude into the conductor connection space with its actuating surface in such a way that the release element can delimit the conductor connection space in the insertion direction of the conductor with its actuating surface.
  • the actuating surface preferably extends transversely to the insertion direction of the conductor to be connected into the conductor connection space.
  • the conductor to be connected When the conductor to be connected is inserted into the conductor connection space, the conductor can hit the actuating surface in the insertion direction in order to actuate the release element in such a way that the release element releases the latching between the actuating element and the housing.
  • the release element is moved in the direction of insertion, as a result of which the release element can slide along the actuation element and the release element can thereby tilt the actuation element in a direction transverse to the direction of insertion, so that the latching of the actuation element with the housing is released and the actuation element can be guided counter to its actuating direction by the spring force of the clamping leg of the clamping spring in order to release the clamping leg so that it can move from the open position into the clamping position.
  • the actuating surface can be formed on an actuating portion of the release element, wherein the actuating portion can extend transversely to a main portion of the release element.
  • the release element can have an L-shape.
  • the release element can have a handle section for actuating the release element manually or by means of a tool.
  • the handle section is preferably arranged at a free end of the release element. If the release element has a handle section and an actuation surface, then the handle section is formed on a free end of the release element that is remote from the actuation surface.
  • the handle section can protrude through a housing slot, with the actuating element also being able to protrude through this housing slot.
  • the release element and the actuating element can thus be guided in one and the same housing shaft.
  • the handle section can protrude from the housing shaft and thus from the housing, so that it can be easily operated by a user.
  • the handle section can also end flush with an outer surface of the housing, so that an unintentional actuation of the release element by means of the handle section can be prevented.
  • the handle section can then have a tool engagement surface, via which the handle section can be actuated by means of a tool.
  • the release element can be actuated by the handle section without the conductor to be connected, which is particularly advantageous in the case of conductors with a very small cross-sectional area.
  • the grip portion is preferably elongate in the shape of a pin or a finger.
  • the connection arrangement can also have a first spring element which can interact with the actuating element.
  • This first spring element can interact with the actuating element in such a way that the first spring element, during the transfer from the open position to the clamping position, applies a spring force against the actuating element in such a way that the actuating element is counteracted not only by the spring force of the clamping leg but also by the spring force of the first spring element the actuating direction of the actuating element is moved in order to be able to ensure complete release of the clamping leg by the actuating element in the clamping position of the clamping leg.
  • the first spring element can thus form a restoring spring.
  • the actuating element can be guided so far in the housing slot in the clamped position that the actuating element is flush with the outer surface of the housing or even protrudes a little out of the housing slot and thus out of the housing.
  • the actuating element can thus also form a display element which shows a user when the clamping leg of the clamping spring is in the clamping position.
  • the first spring element can be arranged with a first free end on an inner wall of the housing and with a second free end on the actuating element.
  • connection arrangement can have a second spring element which can interact with the release element.
  • the second spring element can apply a spring force to the release element, which can act on the release element counter to the insertion direction of the conductor.
  • the second spring element can thus form a return spring. If the release element is actuated in the direction of actuation by means of the conductor to be connected, either manually or by means of a tool, the release element is pretensioned against the spring force of the second spring element, so that the release element automatically returns to its position after actuation and thus the release of the latch between the housing and the actuation element starting position can move.
  • the actuating element can again engage with the release element, in particular in the region of the release of the release element, when transferring from the clamping position to the open position.
  • the second spring element can be arranged with a first free end on an inner wall of the housing and with a second free end on the release element, in particular on the actuating section of the release element.
  • the first spring element and the second spring element can be positioned in such a way that they have the same spring action direction.
