Definitions

  • the invention relates to an electrical connector intended to connect electrical conductors provided with a insulating coating, said connector being able to be mounted mechanically using any source of energy and it includes: [a] a receiving element which has two main edges which form a first non-flat angle, of each of which emerges a wing able to partially surround one of said conductors; and [b] a wedge element provided with two active edges which form a second angle substantially equal to said first angle, said shim element being able to be introduced between said first edges of said receiving element.
  • GB-A-2,065,994 describes a such connector with a solid shim element.
  • US-P-3 848 956 describes a connector intended to obtain an electrical derivation from a underground conductor with an insulating coating without that it is necessary to remove the insulating coating and ensuring a sealing against humidity at the connection points of two conductors.
  • the connector described requires a relatively laborious installation.
  • connectors that include a "C" shaped sleeve and a shim so that the introduction of the shim in the sleeve secures between the conductors to be connected, as well as a electrical connection between these as well through of the sleeve than of the shim.
  • some of these drawbacks in particular of not not suitable for conductors with an insulating coating, to present a difficult assembly and insufficient security in maintaining the connection.
  • the invention proposes to eliminate the drawbacks that we just mentioned. This object is obtained thanks to a connector of the type described in the introduction and which is characterized by the connector according to claim 1.
  • Figure 1 is an exploded perspective view of a embodiment of the connector, object of the invention, in relationship with the two drivers that this is connect. Of these conductors, only a few stretches.
  • Figure 2 is a view similar to the previous view of another embodiment of the connector.
  • the connector includes a receiver element 2 and a wedge element 4.
  • the receiving element 2 is in the form of "VS"; by this expression, we want to indicate that the sections of the receiving element 2 reproduce the shape of the letter C.
  • the receiving element 2 consists of a part central or plate 6 limited in the longitudinal direction by first two edges 8 which form an angle between them flat, i.e. the first edges 8 are not parallel to each other. From each of these first edges 8 emerges a wing 10 having a curvature or several folds so that each wing can partially surround one conductors 12.
  • Each conductor 12 has a insulating coating 14 which surrounds the conductor core 16.
  • the wedge element 4 has two active edges 18 which form between them a second angle substantially equal to the first angle determined by the first edges 8 of the receiving element 2.
  • This wedge element 4 can be introduced between the wings 10 and it is preferable that the outer surfaces of these active edges 18 are concave since between these and the internal surfaces of wings 10, we try to keep the conductors prisoners 12.
  • perforating means 20 which can form successions of teeth (as shown in the figures), be shaped like a blade and other.
  • the perforating means 20 penetrate into the insulating coating until contact with the core of the conductor 16.
  • the element 4 is made of material electrically conductor so as to ensure current flow between the perforating means 20 located in the edges opposite assets.
  • the receiving element 2 has a posterior appendage 22, a depression 24 and a groove 26 which determine a abutment edge 28 which, in a manner known per se, facilitates the retention of the wedge element 4, ensuring good operation.
  • the wedge element 4 is formed by a single sheet of metal which has been deformed as that it is shown, after being folded several times on itself in the longitudinal direction, constituting two substantially equal main loops and a third loop 30. This figuration ensures a satisfactory elasticity to the wedge element 4.
  • the wedge element 4 has a central part 32 which includes a plurality of segments 34, arched outward and directed alternately in opposite directions; these segments extend between the end portions 36 where have been formed the active edges 18; this configuration ensures also a suitable elasticity to the wedge element 4.
  • the receiving element 2 has an appendix 38 which, from the central part or plate 6, projects towards the interior of the space between the wings 10; this appendix 38 is capable of ensuring appropriate retention of the wedge element 4, and at the same time, also good functioning.
  • Any energy source may be suitable for mounting mechanical of the connector and may be of hydraulic origin, supplied by a cartridge or the like.
  • mounting can be easily achieved by simply helping hand tools.
