  • Publication number: 20120100763
    Abstract: An end fitting of a surge arrester has a recess for receiving a rod, wherein the rod can be pressed inside the recess by applying an outer force to the end fitting. Furthermore, a corresponding device for pressing an end fitting and a method for pressing an end fitting are described. The end fitting contains a plurality of body edges delimited in an arc shape. Spaces between points on the body edge delimited in an arc shape and a center point of the recess are equidistant. Thus it is possible to exert a uniform force on all sides on a recess and thus provide an even deformation on all sides of the recess during pressing. As a result, accordingly pressed items, for example rods within the recess, are pressed within the recess on all sides.

    Abstract: In order to make it possible to produce a secure and permanent contact connection between an electrical conductor made from a soft material, in particular an aluminum conductor, and a contact element made from a harder material, the conductor is encapsulated at least partially in a contact region by an electrically conductive material. The electrically conductive material is harder than the soft material of the conductor. The electrically conductive material is applied with the aid of a thermal spraying process, with the result that there is a pressure-free electrical connection between the soft material and the sprayed-on material. Electrical contact is made with the contact element indirectly via the sprayed-on material. The thermal encapsulation by the spraying in the contact region makes it possible for a reliable electrical contact to be made even in the case of soft materials having a tendency towards cold flow.

  • Patent number: 7163753
    Abstract: An arc-resistant terminal, couple, and connecter are provided. In an embodiment, a metal-based electrical contact portion thereof includes at least one of Cu, Ni or Sn, and not more than 0.06 mass % P, wherein the arc-resistant terminal capable of suppressing arc discharge wherein a voltage between the arc-resistant terminal and a second terminal immediately after separation thereof is DC36V to 60V and a current between terminals during contact is 6A to 30A. In another embodiment, the an electrical contact portion comprising at least 80 mass % of metal having a boiling point of not less than 1000 degrees centigrade. According to the present invention, since the electrical contact portion or the final contact portion of the terminal includes a specific metal-based material, even when the voltage applied between the terminals is increased and an arc discharge is liable to be generated, the arc discharge can be suppressed.

  • Patent number: 6793544
    Abstract: The present invention relates to an electrochemical cell having a terminal collector plate element that conducts electrical current from the stack. The terminal plate has an electrically conductive region and an electrically non-conductive region of the surface. The non-conductive region is coated with a corrosion resistant coating that comprises either a passivation layer, a corrosion-resistant polymeric layer, or both. Optionally, the conductive region of the terminal plate may be protected from oxidation, by coating with an oxidation-resistant metal layer. The oxidation-resistant layer may be further coated with a conductive oxidation-resistant polymeric layer. Other preferred aspects of the present invention include methods of treating the terminal plate to resist corrosion and oxidation while still maintaining electrical conductivity.
