Definitions

  • the present invention relates to the field of connection devices and / or electrical connection; the invention relates more particularly to a type of electrical connection device "greenhouse” or type of foot protection for connection to the ground.
  • the conductive connection piece or parts are usually made of copper, because of the excellent conductivity of this material. But this material is heavy and expensive.
  • the invention therefore aims to provide a simple solution to all or part of these problems.
  • the present invention relates to an electrical connection device comprising a connection portion, and at least one fastening device configured to attach an end of at least one conductive wire to the connection portion, the connection portion being made integrally in a non-magnetic material, a layer of a protective material being deposited on at least a portion of the surface of the at least one connecting portion.
  • the layer of protective material protects the non-magnetic material against oxidation.
  • the connecting device can be used directly, without prior cleaning of its surface to remove the oxidized portions.
  • the non-magnetic material is an aluminum alloy.
  • Aluminum alloy is lighter and cheaper than copper.
  • the protective material is tin, or zinc, or silver, or gold.
  • a layer of a bonding material is deposited on the at least a portion of the surface of the connecting portion, between the aluminum alloy and the layer of protective material.
  • the layer of bonding material reinforces the attachment of the layer of the protective material to the surface of the conductive part.
  • the bonding material is copper.
  • the copper layer is deposited with a thickness of 1 micron and 6 microns.
  • first electrical connection device 1 which we will also call wire clamp, and an embodiment of which is shown in FIG. figure 2 .
  • the wire clamp comprises a connecting piece 12 in the form of a cylinder or hollow parallelepiped, delimiting an open cavity or not, and through or not, adapted to the reception of ends of conductive wires. different shapes and / or dimensions, in particular of different diameters or lengths.
  • Each end of this piece is provided with a fixing means configured to fix the end of a conductive wire in contact with the connecting piece.
  • the fixing means comprises a stirrup 2, 3, the stirrup being attached and held against one of the ends of the connecting piece 12, so that the end of the conductive wire is gripped. and held tight between the stirrup 2, 3 and the surface of the connecting piece 12.
  • the connecting piece 12 is made of a conductive material which thus ensures electrical continuity between the conductive wires whose respective ends are fixed at each end of the connecting piece 12.
  • this connecting piece 12 In order to lighten and reduce the cost of this connecting piece 12, and to avoid or limit the formation of eddy currents in the case of high power applications, another non-magnetic material that copper is used to manufacture the connecting piece 12, preferably an aluminum alloy.
  • a layer of a protective material is deposited on all or part of the surface of the connecting piece 12.
  • the protective material may be tin, zinc, silver or gold.
  • tin will be used as the protective material.
  • a layer of copper is deposited on the surface of the connecting piece 12, between the non-magnetic material and the layer of the protective material.
  • the thickness of this copper layer is between 1 micron and 6 microns.
  • the connecting piece or clamp 12 is housed inside an envelope or a box, in two parts 6, 7, as illustrated in FIGS. figures 1 , 3 , and 6 , the housing being made of insulating material, and in which are provided two openings for access respectively to both ends of the clamp 12 for the passage and fixing the ends of the conductive son to be connected.
  • This ground connection piece 10 is made of non-magnetic material, with a layer of protective material deposited on the surface of the part to protect it against oxidation, and preferably with a layer of copper deposited between the non-magnetic material and the layer of the protective material to promote the attachment of the protective material.
  • the protective material may be tin, zinc, silver or gold. Preferably, tin will be used as the protective material.
  • this ground connection piece 10 is attached to the lower surface of the clamp 12 and held firmly in contact therewith by a screw 9 which passes through the clamp 12 from top to bottom. ; this screw 9 also passes through the earth connection piece 10 before being screwed, by its threaded end, onto a bearing piece 16, provided with a threaded orifice which cooperates with the threaded end of the screw 9, the ground connection piece 10 bearing on the support piece 16; the ground connection piece is thus gripped and held tight between the support piece 16 and the wire clamp 12.
