Definitions

  • the invention relates to a conductor terminal for clamping at least one electrical conductor, comprising at least one insulating housing and at least one contact insert, which has at least one clamping spring and at least one bus bar, wherein the clamping spring has a contact portion and a clamping portion formed for clamping the electrical conductor against the busbar, the clamping spring is connected directly or indirectly to the abutment portion at an abutting portion-side end of the clamping portion, wherein the clamping spring has at least one operating portion adjacent to the clamping portion, which is disposed at the end of the clamping portion facing away from the abutment portion side end.
  • the clamping portion of a clamping spring is sometimes referred to as a clamping leg, the contact section as a plant leg.
  • Such a conductor terminal is from the EP 2 400 595 A1 known.

  • the clamping spring has at least one operating section adjacent to the clamping section, which is arranged at the end of the clamping section facing away from the abutment section-side end, wherein the actuating section is designed as an actuating section to be acted upon by a pressing force.
  • a clamping point formed between the busbar and the clamping portion in particular its clamping edge, can be opened. This allows easy insertion of electrical conductors, in particular finely stranded and stranded conductors, as well as the removal of electrical conductors from the conductor terminal.
  • the actuating portion may be made comparatively short, e.g. may have a maximum length of 20% of the length of the clamping portion. In this way, the clamping spring is comparatively compact despite the outgoing from the clamping portion actuating portion and can be accommodated well in small-sized insulating housings.
  • the abutment section serves to abut and support the clamping spring in the insulating housing.
  • the abutment portion is e.g. on a contact surface of the insulating material at this.
  • the clamping spring may for example consist of flat material, for example of a piece of sheet metal, which is bent accordingly.

  • the clamping spring on the clamping portion-side end for example, be fork-shaped with two protruding teeth, which form the actuating portion and the actuating arms.
  • a busbar section of the busbar is arranged between the actuating arms in the closed state of the conductor terminal and without inserted conductor. This allows a space-saving arrangement of said components.

  • the actuating portion extends from the clamping portion before initially substantially in the same direction as the clamping portion and extends in the further course of the effective direction of the spring force of the clamping portion.
  • This directional change in the direction of extension may be formed, in particular, at a distance from the clamping edge on the actuating portion, e.g. such that the actuating portion extends away from the clamping portion initially substantially in the same direction as the clamping portion and extends at a distance from the clamping edge only from the effective direction of the spring force of the clamping portion.
  • the operating portion extends away from the effective direction of the spring force of the clamping portion, it may extend substantially opposite to the effective direction of the spring force of the clamping portion or at an angle thereto.
