Definitions

  • the present invention relates generally to the connection from an electric cable to a conductive element.
  • this conductive element by itself forms a terminal screw connection.
  • This connector which is in practice made of metal, and which can just as well be used for a bare electrical cable, i.e. for a cable electric without cable end, has a wiring block, which, for engaging the electric cable, has at least one hole belonging to a connection terminal, this hole being cut by a hole threaded with which is engaged a clamping screw associated with said terminal connection, the entry face of the wiring block on which the hole opens extending generally obliquely to the axis of this hole.
  • Such a connector is for example described in the document DE-A-1 230 875.
  • the present invention generally relates to provisions to facilitate the implementation of such a connector.
  • a connector of the kind concerned which, according to a first of these provisions, is characterized in that that it comprises a fixing base, which is adapted to allow the subjection of the assembly to the conductive element to which this cable must be connected, in that the entry face of the wiring block overall an acute dihedral with a substantially planar bearing face by which the mounting base is adapted to be applied to the element conductor, and in that the tapped hole intersecting the bore leads to the side of the wiring block opposite the mounting base.
  • the connector of the invention is still characterized in that its fixing base is reduced to a plate opposite which protrudes its wiring block.
  • this arrangement advantageously lends itself to a development according to which the drilling that comprises the wiring block runs right through this wiring block.
  • the drilling of the wiring block is extended, according to another development of the invention, beyond this wiring block, in biting at least in part on the thickness of the plate forming the fixing base.
  • the thickness overall of the connector according to the invention can advantageously find itself reduced accordingly.
  • the plate forming the fixing base of the connector according to the invention comprises, for its securing to the conductive element to which the cable electrical must be connected, at least one notch which opens on the side opposite the entry side of the wiring block.
  • this wiring end piece 12 comprises, on the one hand, a metallic active part 13, which is set on the previously stripped end of the core conductor 14 of the electric cable 11, and, on the other hand, a collar of insulating material 15, which is engaged on the sheath in insulating material 16 thereof.
  • the element conductor 10 is for example a distributor bar forming by itself connection terminals 17, this bar of distributor, whose cross section is rectangular, presenting, from place to place, perpendicular to its faces main, tapped holes 18 with which to cooperate clamping screws 19.
  • a connector 20 is used to connect the electric cable 11 to this element conductor 10.
  • this connector 20 comprises, overall, on the one hand, a wiring block 21, which, for the engagement of the electric cable 11, has at least one hole 22 belonging to a connection terminal 23, and, on the other part, a mounting base 25, which, according to arrangements described in more detail later, is adapted to allow subjecting the assembly to the conductive element 10 to which the electric cable 11 must be connected.
  • the hole 22 is generally cylindrical, and its cross section is circular.
  • the input face 26 of the block of wiring 21, i.e. the face of this wiring block 21 on which opens the bore 22 which it comprises, extends generally oblique to the axis of this bore 22.
  • the mounting base 25 having a support face 28, substantially planar, by which it is adapted to be applied to the conductive element 10, according to one of the main faces thereof, the entry face 26 of the wiring block 21 generally makes a sharp dihedral, of angle A, with this support face 28.
  • this angle A is between 30 ° and 60 °, preferably being close to 45 °.
  • the base of fixing 25 is reduced to a plate opposite which the wiring block 21 protrudes, and, in practice, this plate extends entirely on the side of the wiring block 21 opposite its entrance face 26.
  • the plate forming this base of fixing 25 is level with the wiring block 21.
  • this wiring block 21 does not protrude that on one of the faces of the plate forming the base of attachment 25, that opposite to its bearing face 28.
  • the drilling 22 that includes the wiring block 21 crosses right through this wiring block 21, and, extending beyond it, it bites at least in part on the thickness of the plate forming the fixing base 25, forming, on the surface of this plate, a chute 29 with a blind end 30.
  • the block wiring 21 comprises, parallel to one another, several holes 22, and the plate forming the fixing base 25 generally extends parallel to the plane containing the axes of these holes 22.
  • three holes 22 are planned side by side.
  • the holes 22 are each intersected transversely by a tapped hole 32, which leads to the face of the wiring block 21 opposite the plate forming the mounting base 25, and with which is engaged a screw tightening 33.
  • the head 34 of this clamping screw 33 is a mixed head, that is to say a head which includes both a diametrical groove 35 which opens at its periphery at both ends, and, at the same time, crosswise with the previous one, a groove 36 whose both ends are against blind.
  • the plate forming the fixing base 25 comprises, in the embodiment shown, at least one notch 38, which opens on the side opposite to the entry face 26 of the block of wiring 21.
  • this plate thus comprises, at least two notches 38 parallel to each other.
  • the notches that the plate forming the connector fixing base according to the invention comprises for securing the assembly to the conductive element to which one or more cables must be connected can be replaced by holes.
  • the connector according to the invention is indeed suitable just as well in case these electrical cables are bare, that is to say without any cable end, their engagement in one of its piercings then being done simply by their stripped ends following the same process as that described.
