Definitions

  • the invention relates to a pin for electrical connectors consisting of a metallic body made of a material which can be deformed by the application of pressure, said body being provided with a cylindrical axial opening for receiving the cable to be connected mechanically and electrically to the pin, this invention is characterized in that the wall of the orifice for receiving the wire comprises at least one rib forming a sharp-angled inner projection, made in the material constituting the pin and placed virtually transversally across the axis of the opening.
  • the pin for electrical connectors consists of a metal-' lic body made of a material which can be-deformed by the application of pressure, said body being provided with a cylindrical axial opening for receiving the cable to be connected, mechanically and electrically to the pin.
  • the invention is characterized in that the wall of the orifice designed to receive the wire comprises at least 1 one rib forming a sharp-angled inner projection made in the material constituting the pin and placed virtually transversally across the axis of the opening.
  • the projections are made by threading the inner wall of the orifice.
  • FIG. 1 is a partial sectional view of a connector with a male pin according to the invention. 1
  • FIG. 2 is a detailed sectional view of one of the pins in FIG. 1, not yet in the fixed position.
  • FIG; 3 is a detailed view of FIG. 2, the pin being in the fixed position on its cable.
  • the object of the present invention is therefore to produce pins for connectors, said pins 1 having a male end 1 (see FIG. 1) or a female end as well as anopening 2 for receiving thewire to be connected electrically to the pin,
  • the pin enables insulated electric cables 3 to be received, that is, cables provided with a sheath 4 made of an elastic material, such as a plastic material, without it being necessary, before hand, to expose the core of the cable over the part mechanical connection to be obtained between the cable and the pin.
  • the pin is made of a material which can be flattened or deformed by pressure exerted with the aid of pliers, and has a body of a generally cylindrical form of small diameter (about 3 At one of the ends of this body an orifice 2 is made which comprises, on its inner wall, some transversal sharp-angled projections so that the points 5, of these projections can penetrate transversally into the insulating sheath 4, whenthe pin is being fixed onto the cable with the help of pliers, in order to flatten and anchor themselves into the core 6, as is shown in FIG. 3.
  • a good mechanical and electrical connection is thereby obtained between the body 1 of the pin and the core'6 of the cable, without it being necessary, before hand, to expose the cable.
  • the projections 5 can be made in the form of annular ribs placed on all or part of the length of the opening 2, or else, preferably, in the form of a helicoidal thread (see FIGS. 2 and 3).
  • the height of the projections or the depth of the pitch of the thread is such that it is at least equal to the thickness of the insulating sheath of the cable, so that the material constituting this sheath can lodge itself between the projections or the threads without offering too much resistance during the gripping operation.
  • the pin according to the invention enables electric cables to be connected simply and rapidly, since the relatively long operation involved in exposing the cable is eliminated, which is particularly advantageous when it is desired to grip cables of small diameter (about 1 m/m) inthe pins whose outer diameter is of the order of 3 m/m.
  • a tenninal pin for an electrical connector adapted for use with a cable having an outer insulating jacket said terminal pin comprising an elongated body having an annular wall defining an axial recess for receiving a terminal end portion of said cable inserted therein for electrical and mechanical connection thereto, said body formed of electrically conductive material deformable by inward radial pressure to grip'said terminal end portion of said cable, said wall having an internal recess surface comprising a continuous helical thread generated around the longitudinal axis of said recess, said thread having continuous opposite side surfaces intersecting along a sharp angle apex for penetration into said cable upon compression of said body.
