Definitions

  • the invention relates to an electrical connector intended to connect electrical conductors provided with an insulating coating, said connector being capable of being mechanically mounted by means of any energy source and it comprises: [a] a receiving element which has two main edges which form a first non-flat angle, from each of which emerges a wing capable of partially surrounding 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 wedge element being able to be introduced between said first edges of said receiving element.
  • US-P-3 848 956 describes a connector intended to obtain an electrical derivation from an underground conductor provided with an insulating coating without having to remove the insulating coating and ensuring a seal against humidity at the points connection of the two conductors.
  • the connector described requires a relatively laborious installation.
  • Connectors are also known which include a "C" shaped sleeve and a shim so that the introduction of the shim into the sleeve provides a fixing between the conductors to be connected, as well as a connection. electric between them both through the sleeve and the shim.
  • some of these conductors have drawbacks, in particular of not being suitable for conductors provided with an insulating coating, of presenting a difficult assembly and insufficient security in maintaining the connection.
  • the invention proposes to eliminate the drawbacks which have just been mentioned. This object is obtained by means of a connector of the type described in the introduction and which is characterized in that said wedge element comprises an electrically conductive material and said active edges of said wedge element have perforating means capable of biting on the outside. in said electrical conductors for the perforation of said insulating coating.
  • Figure 1 is an exploded perspective view of an embodiment of the connector, object of the invention, in relation to the two conductors to be connected. Of these conductors, only a few sections are represented.
  • Figure 2 is a view similar to the previous view of another embodiment of the connector.
  • the connector comprises a receiving element 2 and a shim element 4.
  • the receiving element 2 is in the shape of a "C"; by this expression, we mean that the cross sections of the receiving element 2 reproduce the shape of the letter C.
  • the receiving element 2 consists of a central part or plate 6 limited in the longitudinal direction by two first edges 8 which form between them a non-flat angle, that is to say that 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 of the conductors 12.
  • Each conductor 12 has an 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 outer surfaces of these active edges 18 are concave since between them and the inner surfaces of the wings 10, it is sought to keep the conductors 12 prisoners.
  • perforating means 20 which can form successions of teeth (as shown in the figures), be in the form of a blade and the like.
  • the wedge element 4 When the wedge element 4 is inserted with sufficient force between the wings 10, by housing the conductors 12, the perforating means 20 penetrate into the insulating coating until contact is established with the core. of the conductor 16.
  • the element 4 is made of electrically conductive material so as to ensure the passage of current between the perforating means 20 situated in the opposite active edges.
  • the receiving element 2 has a posterior appendage 22, a depression 24 and a groove 26 which determine an abutment edge 28 which, in a manner known per se, facilitates the retention of the 'wedge element 4, ensuring proper operation.
  • the wedge element 4 is formed by a single sheet of metal which has been deformed as it is shown, after having been folded several times over itself in the longitudinal direction, constituting two substantially equal main loops and a third loop 30. This figuration provides satisfactory elasticity to the wedge element 4.
  • the wedge element 4 comprises a central part 32 which comprises a plurality of segments 34, arched outwards and directed alternately in opposite directions; these segments extend between the end portions 36 where the active edges 18 have been formed; this configuration also ensures an appropriate elasticity for the wedge element 4.
  • the receiving element 2 has an appendage 38 which, from the central part or plate 6, projects towards the inside of the space between the wings 10; this appendage 38 is capable of ensuring appropriate retention of the wedge element 4, and at the same time, also a good functioning.
  • Any energy source may be suitable for the mechanical mounting of the connector and may be of hydraulic origin, supplied by a cartridge or the like.
  • the assembly can be easily carried out by simply using hand tools.
