Definitions

  • the invention relates to a contacting device for producing an electrical contact between at least one electrical conductor and an electrical component according to the preamble of patent claim 1.
  • a generic contacting device is from the EP 2 082 472 B1 known. There, a contacting of several coils of an electric motor by connecting elements and with these integrally formed contact elements is described. Press-fit pins provide a connection to a connection arrangement designed as a printed circuit board.
  • the object of the invention is to provide a contacting device which is easier to manufacture and assemble and ensures permanent contact.
  • connection is made by means of a contact plate, which in turn is mounted in a wall of the component, can be dispensed with conventional connectors completely.
  • the electrical conductors or cables can be connected directly to the component by means of the contact board. This connection is very safe, allows high currents and requires only a minimal amount of space.
  • the component is designed as a coil housing of an electrical coil and the contact plate is mounted in an opening of the wall.
  • the contact plate is provided with a welding hook, with which the ends of the electrical conductors of the electrical component, in particular the coil, can be permanently connected in a simple manner.
  • connection of the electrical conductors with the press-in contacts is particularly preferably via crimp connections, via welding sleeves or solder joints.
  • FIG. 1 An in Fig. 1 exemplified in cross-section component 10 is formed by a housing of a coil. Between two lateral walls 12, a space 11 is formed for a winding, not shown, of the coil.
  • a projection 14 is arranged or formed on the outside.
  • the projection 14 may be formed integrally with the wall 12 or separately formed and positively connected, for example by clips with this.
  • the projection 14 has two parallel, perpendicular to the wall 12 extending walls 15. In one of these walls 15, an opening 16 is formed, opposite thereto in the other wall 15, a groove 18.
  • the opening 16 and the groove 18 serve to receive and fix a contact board 20 at a defined distance from the wall 12.
  • the projection 14 with his Walls 15 is preferably total, but at least in the region of the opening 16 and the groove 18 made of an electrically non-conductive material, in particular of plastic.
  • the contact board 20 is formed of an electrically conductive material, such as a metal sheet. It has a straight web 22, which is positively inserted into the opening 16 and dips with a pointed cutting edge 28 at one end into the groove 18 and digs into it. At the other, free end of the web 22 merges into an angled portion on which a welding hook 26 is formed.
  • the welding hook 26 is flexible and serves to receive and permanently attach an end of a wire forming the unillustrated winding of the coil.
  • the contact board in the area lying between the walls 15 preferably two wedge-shaped tapered inclined surfaces 25 on both sides, which are limited to the side of the welding hook 26 out of two locking lugs 27.
  • the contact plate is pressed under a pressure force in the opening 16.
  • the latching lugs 27 then lie down after being pressed in against the inside of the wall 16 having the opening 16, so that the contact plate is permanently held in the walls 15 of the projection 14 in a form-fitting manner.
  • the contact plate 20 has in the area mounted between the walls 15 a press-in hole 24 which serves for the positive reception of a hook-shaped press-in contact 30, which is pressed with its tapered tip 31 by applying a compressive force in the press-fit.
  • the press-in contact 30 has at the other end a connection 32 to at least one electrical conductor 40, 42.
  • This compound may be formed as a solder joint, but is particularly preferably formed as a crimp connection 34 and in this case especially as a B-crimp connection, as in Fig. 2 is shown.
  • connection between the press-fit contact 30 and the at least one electrical conductor 40, 42 can also be made by means of a wound on a square or round extension 29 on the press-fit 30 wire 36, as in Fig. 7 is shown.
  • the wire winding 36 can additionally by means of a welding sleeve 38, as in Fig. 6 shown, or by means of a solder cap 39, as in Fig. 8 represented, be secured to the extension 29 electrically conductive.
  • connection types are also suitable for the connection of at least one electrical conductor to the welding hook 26.
