Definitions

  • the invention relates to an electrical connection terminal with a first and a second plate, which are angled relative to one another to form a bending edge, and with at least one receiving slot provided at right angles to the bending edge in the first plate for an electrical conductor, the receiving slot at one of the Bending edge facing away edge of the first plate forms an opening for pressing in the conductor directed transversely to the receiving slot and the first plate is cut free from a sheet metal blank and bent up to form the bending edge between side walls of a U-shaped contact organ section.
  • Such an electrical terminal is known from EP-B1-00 63 206.
  • the partial plates of the terminal which delimit the receiving or contacting slot should be as rigid as possible so that they cannot twist too much when a conductor is pressed into the receiving or contacting slot.
  • the side walls, bottom wall and partial plates consist of the same material in such a connecting terminal, the partial plates cannot be made thicker than the bottom wall and side walls.
  • GB-A-2 004 425 discloses a further contact element with a U-shaped cross section, in which two mutually parallel plates, each provided with a receiving slot, are bent at right angles from one side wall and protrude into the cut-outs of the opposite second side wall.
  • the object of the present invention is to develop a connecting terminal of the type mentioned at the outset in such a way that the two partial plates delimiting the receiving slot are particularly stable, at least in the region of the slot section in which the conductor pressed into the slot assumes its end position.
  • this object is achieved in that the side walls on both sides of the first plate have cutouts extending over a region of the height of the side walls close to a base wall, that the first plate is provided with widenings projecting into the cutouts in the area of the cutouts, and that the widenings with end sections are angled into the plane of the side walls.
  • the receiving slot continues beyond the bending edge as a gap-free separating slot into the second plate formed by the bottom wall with a closed slot end provided in the second plate.
  • the closed slot end is formed by a circular disk-shaped or oval cutout.
  • the connecting terminal according to the invention is explained in more detail below with reference to a figure.
  • FIG shows roughly schematically and greatly enlarged, omitting all details that are not absolutely necessary for understanding the subject matter of the invention, in an oblique view, a contact organ section 9, in which a receiving slot 1 is provided for pressing in a conductor, not shown, directed transversely to the receiving slot.
  • the contact element section 9 can be integrally connected on one side with a contact spring or a contact pin, while on the other side it merges into a further section of the contact element, which e.g. is designed to intercept an insulating jacket of the conductor.
  • the contact element section 9 shown is produced by stamping and bending from an electrically highly conductive sheet. It consists of a bottom wall 7 and two opposing side walls 8, which together form a U-profile.
  • a first plate 6 is cut free from the sheet metal blank from which the contact element section 9 is made and is bent up around a bending edge 2 between the side walls 8, whereby the plate 6 forms a right angle with a second plate 4 formed by the bottom wall 7.
  • the receiving slot 1 is also open on the open side of the U-profile, so that an inserted into the U-profile Conductor can be pressed into the receiving slot 1 from this side.
  • the slot 1 extends to the bending edge 2 and continues from its closed end around the bending edge 2 as a gap-free separating slot 3 in the second plate 4 or the bottom wall 7.
  • the separating slot 3 thus has an end which merges into the receiving slot 1 and a closed end 5 in the bottom wall 7 which faces away from the receiving slot 1.
  • a circular cut-out is provided to prevent cracking in the bottom wall 7 in the extension of the separating slot 3.
  • the first plate 6 is provided up to a certain height of the side walls 8 starting from the bottom wall 7 with widenings 11 which protrude into window-like cutouts 10 of the side walls 8. These cut-outs 10 in the side walls 8 are shaped such that the first plate 6 or the partial plates 14 with the widenings 11 can be bent out of the plane of the bottom wall 7 together with the side walls 8.
  • End sections 12 of the widenings 11 facing away from the receiving slot 1 and parallel to this are angled within the cutouts 10 into the plane of the side walls 8 and are thus aligned with the side walls 8.
  • the partial plates 14 delimiting the receiving slot 1 in a section 13 of the slot 1, in which a conductor pressed into the slot 1 assumes its end position is additionally stabilized.
