Definitions

  • the invention relates to a connection terminal for the electrical connection of conductors, comprising a housing, with at least one arranged in the housing clamping means for clamping a conductor, and having at least one cooperating with the clamping device actuator for actuating the clamping device, wherein the clamping device is a contact element with a contact surface for contacting a conductor to be clamped in and wherein the clamping device has a transmission element which can be actuated by means of the actuating device and cooperates with the contact element.
  • a terminal which several contact springs for contacting the having electrical conductor.
  • a first contact spring is provided, which is deformable by means of a pivot lever.
  • a second contact spring also serves for contacting the electrical conductor and is pressed by means of the first contact spring against the electrical conductor.
  • the present invention has the object to provide a terminal, which allows a particularly reliable contacting of an electrical conductor.
  • the contact surface extends in a contact region which on the side facing away from the contact surface has a force application surface, which cooperates with a force transmission surface of the transmission element, so that in a closed state of the clamping device, the transmission element with his Power transmission surface exerts a compressive force on the force application surface, wherein the contact region transmits the pressure force through the contact region from the force application surface to the contact surface.
  • a contact region is provided, which is bounded on the one hand by the contact surface for contacting an electrical conductor and on the other hand by a force application surface.
  • the transmission element has a force application surface, which exerts a compressive force on the force application surface of the contact region, so that the contact surface opposite the force application surface is pressed against an electrical conductor to be clamped.
  • the pressure exerted by the transmission element compressive force extends preferably perpendicular to the force application surface and to the contact surface, so that a particularly good power transmission is ensured.
  • a particularly reliable electrical contact with a conductor to be clamped results when an electrical contact of the clamping device with a conductor to be clamped can be produced by means of the contact surface of the contact element and not by means of the transmission element. This defines a locally limited contact area.
  • the transmission element thus does not serve for contacting the conductor, but exclusively for applying force to the contact region.
  • the housing has an insertion region delimited by the contact element for introducing a conductor to be clamped, wherein the insertion region tapers in the insertion direction of the conductor, the insertion region in the region of the contact region of the contact element passing through in a closed state of the clamping device Introduction of a conductor in the form of a solid wire is expandable.
  • the widening of the insertion region is accompanied by a change in position and / or a change in shape of both the contact element and the transmission element.
  • a frictional chain of the electrical conductor to be connected, the contact surface of the contact region, the force application surface of the contact region and the Power transmission surface of the transmission element can be created.
  • the transmission element is resilient and is preferably made of a metallic material. This allows a particularly simple transmission of a force to the contact region of the contact element.
  • the pressure force is generated or generated by means of residual stress of the transmission element. This has the advantage that a compressive force can be provided largely independent of tolerances of the actuator.
  • the contact element is resilient and is preferably made of a metallic material. This allows a simple adaptation of the contact area to electrical conductors with different diameters.
  • the transmission element and the contact element are mutually different components. In this way, a relative mobility of these components can be easily realized.
  • the transmission element is mounted on the contact element, in particular pivotally. This mobility of the contact element supports a largely force-free introduction of an electrical conductor to be clamped, in particular in an open position of the actuating device.
  • the transmission element and the contact element are formed integrally with each other. In this way, a particularly simple design and mountable terminal can be created, which also has a particularly high fire safety.
  • the actuating device has a cooperating with the transmission element actuating portion, which is arranged in a space bounded by the contact element and the transmission element intermediate space. This allows the transmission element to be actively lifted off or lifted off the contact element, thereby assisting the insertion of a litz wire into the insertion area.
  • the actuating portion has an actuating surface which cooperates with a support surface of the transmission element in an opening position of the actuating device corresponding to an opening state of the clamping device.
  • the clamping device can be held in a particularly reliable manner in an open state, regardless of any residual stress state of the transmission element.
  • the actuating portion has a contact surface which cooperates in a corresponding to the closed state of the clamping device closed position of the actuating device with a contact surface of the transmission element.
  • an end position of the transmission element can be defined, whereby a pressure force exerted by the transmission element on the contact region is limited. This is particularly advantageous when a solid wire is introduced with deformation of both the contact element and the transmission element in the insertion of the terminal.

  • the actuating lever 32 also has an angle to the actuating surface 40 arranged contact surface 42, which cooperates in a closed position of the actuator 28 in the manner described in more detail below with the clamping device 30.
  • the clamping device 30 comprises a metallic, spring-elastic transmission element 44 and a metallic, preferably spring-elastic contact element 46.
  • the transmission element 44 has a first portion 48 which extends between a free end 50 of the transmission element 44 and a power transmission region 52.
  • the first section 48 has, on its side facing the actuating section 38 of the actuating lever 32, a surface which cooperates as a supporting surface 54 with the actuating surface 40 of the actuating section 38 and as a contact surface 56 with the contact surface 42 of the actuating section 38.

  • the base portion 62 serves to support a contact rail 64, which for the electrical connection of at least mutually parallel clamping points for at least two conductor 12 to be electrically connected to each other is used.
  • the transmission element 44 has an end section 66. This is provided with an opening 68 which is aligned with the insertion opening 20 of the housing and also serves to introduce the conductor end 22 of the conductor 12.
  • the insertion opening 20 and / or the opening 68 is or are peripherally closed.

  • the power transmission surface 58 of the transmission element 44 is lifted from the force application surface 84 of the contact portion 80 of the contact element 46. This is achieved in that the actuating portion 38 with its actuating surface 40, the support surface 54 of the first portion 48 of the transmission element 44 is supported. Due to the spatial distance between the force transmission surface 58 and the force application surface 84, the contact element 46 in the storage between bearing portion 72 and tab 70 is pivotally movable so that a conductor end 22 of an electrical conductor 12 is practically force-free in the insertion region 26 can be inserted.
