Definitions

  • an electrical switch contact is often used with a metal spring provided a contact piece realized.
  • the contact spring is mechanically or electrically via an actuator with high Switching frequency between open and closed position back and forth emotional.
  • the contact piece usually consists of a spherical or crown-shaped Rivet riveted to the outer area of the contact spring and special is well conductive.
  • JP-A-01241722 is a contact element with the in the first part of the Claim 1 specified features known. There that points in a contact spring provided hole protruding inwards on itself press into the cylindrical rivet shaft during the riveting process.
  • the rivet connection should have a mechanical strength and have low electrical contact resistance. Still emerging Current heat should be dissipated as well as possible into the contact spring become; therefore there is also high thermal conductivity of the riveted joint he wishes.
  • the object of the invention is to damage the contact spring material to minimize during the riveting process and still good mechanical, thermal and electrical connection between the contact rivet and the contact spring guarantee.
  • the rivet punch is designed so that its end profile protrudes further in certain edge areas than in the middle. This The difference in length should not be greater than the total, due to that Rivet hole protruding length of the rivet shaft.
  • Fig. 1 the free end of a contact spring 11 is shown with an actuating element 12 which can be guided, for example, by a mechanical actuator.
  • actuating element 12 which can be guided, for example, by a mechanical actuator.
  • a rivet hole 13 is punched, which has to the side edges of the contact spring 11 through two round bulges fourteenth
  • the axis running through the two bulges 14 need not be completely perpendicular to the side edges of the contact spring 11 ; in certain cases it is advantageous to align them slightly twisted.
  • a conventional mushroom-shaped contact rivet 15 is shown with a spherical top 16 and a cylindrical rivet shaft 17 on its underside.
  • the rivet shaft 17 is pushed through the rivet hole 13 up to the stop with the upper side 16 of the contact rivet 15 .
  • the contact spring 11 and the contact rivet 15 are then connected in a riveting process by means of a stamp 18 .
  • the punch 18 compresses the softer material of the rivet shaft 17 so that a positive connection between the rivet 15 and contact spring 11 is formed.
  • the stamp 18 has no flat end, but is milled out like an arch, so that it has two longer edge areas 19 . During the riveting process, therefore, only the areas of the rivet shank 17 located under these edge areas 19 are compressed, and only then and correspondingly weaker is the inner area.
  • the cross section of the punch 18 is circular and larger than that of the cylindrical rivet shaft 17 .
  • Fig. 3 shows the free end of a finished contact element.
  • the improvement in the mechanical, thermal and electrical connection properties is based above all on the greater surface contact between the contact spring 11 and the rivet 15 achieved by the bulges 14 .
  • the special shape of the plunger 18 causes the rivet shaft 17 to be more strongly compressed in the corresponding edge regions and thus a material accumulation in the bulges 14.
  • the above embodiment relates to the attachment of a Contact rivets on the free end of a contact spring.
  • the invention is also at comparable rivet connections, e.g. the rivet connection of the lower one End of the contact spring with the connector such as a relay, applicable.
  • non-circular rivet hole 13 Alternative configurations of the non-circular rivet hole 13 are also conceivable, for example with three or more bulges 14 and correspondingly shaped rivet punches 18 .
