Definitions

  • the contact carriers can be manufactured almost without waste.
  • the wire is bent in a meandering shape to form a band of connected, alternatingly opposing contact elements.
  • the individual contact elements are then obtained by separation along the central axis of this band.
  • FIG. 3 shows a somewhat modified contact element in front view
  • FIG. 4 shows an embossing device with a contact element in three views
  • FIG. 5 shows a band of cohesively formed contact elements according to FIG. 2.
  • the relay shown in FIG. 1 has a customary design. construction with a coil body 1 serving as the base body, which is shown without winding.
  • the magnet system of the relay is drawn schematically with a core 2, but 3 and an armature 4.
  • a contact spring 5 is actuated as a central contact spring, which has a strand connection 6, which is only partially drawn.
  • two counter-contact elements 10 are anchored in corresponding openings, each of which is flat-stamped in its upper regions 8 and each provided with a welded-on contact piece 9. The more precise design and manufacture of these contact elements 10 is explained in more detail with reference to the following figures.
  • FIG. 4 shows the shape of the contact element in an embossing tool.
  • This tool consists of an embossing receptacle 23 with an embossing recess 24 which defines the fit or the limits of the contact element and an embossing stamp 25 which is not shown in the top view of FIG. 7.
  • the contact element 10 or the pre-bent wire 26 is inserted into the embossing receptacle 23 and then embossed into the corresponding shape with the embossing stamp 25, the contact tongue 14 in particular being embossed from the original contour 15 into the contour 16.
  • the embossed receptacle 23 has an elevation 27, in which a recess 28 is provided to form the welding region 17 mentioned. Before that, however, the area of curvature is embossed on contact by means of lateral embossing dies which are introduced in the direction of the arrows 29.
  • FIG. 5 shows a section of a continuous band 30 of contact elements 10, which are formed contiguously by a wire 26 in the form of a serpentine bend.
  • the individual contact elements 10 can, for example, bundle tools are successively embossed on the form and provided with contact pieces. Only the finished contact elements 10 are then obtained by removing the middle pieces 31 along the central axis of the band 30.

Abstract

L'élement de contact (10) est formé dans un fil rond, ce fil rond étant plié en forme d'épingle à cheveux comportant deux branches parallèles (11, 12) dont au moins l'une sert de broche de connexion soudée. La zone courbée entre les deux branches est aplatie en une zone de contact commune (14) à surface plane et dotée d'un plot de contact. Ceci permet, de manière particulièrement avantageuse, de munir des contacts pour courant fort de connexions de carte de circuits.
