Definitions

  • the present invention relates to an electrical contact member intended to provide an electrical connection between an electrical conductor, on the one hand, and a male electrical contact member, on the other hand.
  • the contact member according to the invention is of the type produced from a metal blank which is a good conductor of electricity and endowed with a certain elasticity, cut and folded to present, on the one hand, a means of insulation displacement connection and, on the other hand, a conduit intended to receive the male electrical contact member, said blank being cut to present a core with, in the vicinity of one end, two tabs arranged on each side of the blank, said tabs being folded to extend perpendicular to the core and each having, on the side of the free end of the core, a slot to form the insulating displacement connecting member.
  • the present invention aims to improve the structure of the organ, as defined in the characterizing part of claim 1.
  • a contact member of very practical use is thus produced, which ensures a perfect electrical connection.
  • the flap has slots intended to be crossed by the bars of the corresponding edges of the tabs.
  • the tongue has a stamped part forming a projecting part opposite the internal face. of the flap. This improves the contact between the tongue and the male organ.
  • the flap comprises a stamped forming a projection on its internal face turned opposite the tongue.
  • the male organ is perfectly enclosed between the tongue and the flap.
  • the tongue is arched so as to tend to approach the internal face of the flap, the edge of the core opposite to that provided with the tongue comprising retaining means.
  • the free end of the tongue has a notch determining two projections while the edge of the core, opposite to that secured to the tongue, has a T-shaped notch having a central branch intended to fit into the notch and two lateral branches constituting stops for the projections.
  • Figure 1 is a plan view showing an electrical contact member cut from a blank of metallic material good conductor of electricity.
  • Figures 2 and 3 are perspective views showing different stamping phases of the blank of Figure 1 to obtain the contact member.
  • Figure 4 is a perspective view of the electrical contact member.
  • Figure 5 is a sectional view along line 5-5 of Figure 4.
  • Figure 1 shows a contact member according to the invention, which was made in a blank of an elastic metallic material good conductor of electricity.
  • the member which bears the reference 1 at one end, comprises on both sides of a core 6 two legs 2 and 2 a , the leg 2 having a slot 3 on the side of the free end of the member 1, while its free edge is cut to form a bar 4 and a lug 5.
  • Tab 2 a is formed in the same manner that the leg 2 and comprises a slot 3 has a web 4 a and 5 a pin.
  • the legs 2 and 2 a are intended to be folded along lines 7 to extend perpendicular to the core 6.
  • a T-shaped notch is formed to form a retaining hook 14 intended to extend perpendicular to the core and whose central branch 14 a is intended to be inserted in the notch 10 after bending the tongue 8, while the lateral branches are intended to constitute stops for the projections 11.
  • the core 6 is terminated by a flap 16 which comprises, in the vicinity of its free end, two slots 17 and in its central part, a stamped portion 18.
  • the flap 16 has a width slightly greater than the interval separating the two legs 2 and 2 a and the slots 17 are separated by a distance corresponding to the distance separating the two bars 4, 4 a .
  • the tabs 2 and 2 a are bent at right angles to the core 6, then the tongue 8 is folded down to extend above the core 6, the hook 14 then being folded so that its branches 14 b are placed above the projections 11. Finally, the flap 16 is folded so that the slots 17 are located in line with the bars 4, 4 a , these passing through said slots and being folded against the corresponding face of said flap 16. A conduit 19 is thus produced for receiving a male electrical contact member 20.
  • the tongue 8 is folded so that, by the elasticity of the material, it tends to move away from the core, the branches 14 b constituting stops which, by cooperating with the projections 11, make it possible to limit the action elastic in order to provide in the duct 19 a free space between the internal face of the flap 16 and the tongue 8, said libret space being sufficient to allow insertion of the male flat contact member 20, the latter being pinched elastically between , on the one hand, the pressed 9 and, on the other hand, the pressed 18.
  • the electrical contact member according to the invention is intended to be inserted in a housing of a housing insulator, the pins 5 and 5a penetrating into the thickness of the material of the housing to ensure the locking of said member.
  • the legs 2 and 2a with the slots 3 and 3a constitute an electrical connecting member referred to as "insulation displacement".
  • the width of the slots 3, 3 a is in fact less than the section of an electrical conductor 21 coated with an insulating sheath, so that, when the latter is inserted into the slots, the edges of the latter cut the insulator and bear against the conductor's soul.
  • the insulating housing may include means for locking the conductor 21 so that, once inserted into the slots 3, 3 a , it cannot be released.
