Definitions

  • the invention relates to the production of male electrical contact members of the type comprising a body substantially of U-shaped section, one end of which is extended to form a bar intended to be inserted into a female electrical contact member, while the other end comprises means for enabling it to be connected to an electrical conductor, these means generally being either simply crimping lugs or a member known under the name "insulation displacement connection".
  • the contact members of this type are produced in thin metal blanks of a good electrically conductive material suitably cut and folded. firstly, that the strip is cut and, secondly, that the various parts constituting the member are folded and that after mounting of the conductor certain parts are crimped.
  • the bar which constitutes the electrical connection element with the corresponding female member must, on the other hand, have a certain mechanical resistance and have a greater thickness than the rest of the body.
  • the bar is formed by cutting from the strip a part of a width greater than that of the bar to be obtained and a part is made either with a U section or with an L section, the thicknesses of which are folded down and applied one against the other.
  • the bar does not always have the same thickness. It can also have differences in shape, the thicknesses can be more or less applied one against the other, which affects the good quality of the electrical connection.
  • the U-shaped body part adjacent to the bar is compulsory. thinner, which forms an area of less resistance.
  • One of the aims of the present invention is to remedy these various drawbacks.
  • the male member of electrical contacts is of the type comprising a body of substantially U-shaped section with two wings and a core and one end of which is extended by a bar, while the other end comprises means for its connection to an electrical conductor, said member being produced by cutting and folding from a metal blank which is a good conductor of electricity having two strips having different thicknesses, and is characterized in that the bar and the U-shaped part of the body , adjacent to the bar are cut from the strip having the greatest thickness.
  • the bar has the appropriate section directly and it is ensured that the part adjacent to the bar of the body is not weakened.
  • the bar is cut in the strip so as to extend in the extension of the free end of one of the wings and is folded, on the one hand, to be brought closer to the other wing and , on the other hand, to extend in a median plane passing through the soul of the body.
  • the body comprises a slot extending transversely to the bar, the bar in its part adjacent to the slot being folded against the bottom of the core.
  • the male member is cut two by two spade heads, in a metal blank, good conductor of electricity having a thick median band and two thin lateral bands. This saves a significant amount of blank material.
  • the means of connection to an electrical conductor are of the displacement type of insulation and constituted by tabs cut in the core and folded to extend between the wings and in the free edges of which slots are made.
  • the means of connection to an electrical conductor are of the insulating displacement type and consist of two branches folded to form with the core a part with a U-section and each extended at each end by a tab. , the legs being folded so that those of one of the branches extend opposite those corresponding to the other branch.
  • the part of the body comprising the means of connection to an electrical conductor, of the type with displacement of insulation and adjacent to the part comprising the bar is reinforced by a rib.
  • the branches are reinforced by stampings.
  • the end of the body opposite to that comprising the bar is provided with crimping lugs for an electrical conductor.
  • the part of the body provided with crimping lugs and adjacent to the part of the body comprising the means for connection to an electrical conductor of the insulating displacement type is reinforced by a rib.
  • Figure 1 shows in perspective a metal blank 1 good conductor of electricity for the production of male electrical contact members intended to cooperate with female electrical contact members.
  • the blank is preferably coated, for example tinned.
  • the blank 1 has a relatively large thickness and is subjected to machining so as to provide a central strip 2 having the initial thickness and two lateral strips 3 and 4 having a thinner thickness.
  • the machining can be any, for example, milling.
  • a male contact member 7 comprising three parts 13, 6 and 8.
  • Part 13 is terminated, at its free end, by a bar 5 intended to be inserted in a female contact member corresponding.
  • the part 13 is cut to be folded into a U with a core 9 and two wings 10 and 11, the core 9 being pierced with a hole 12 for fixing in an channel of an insulating housing, while the wing 10 is extended by the bar 5.
  • the part 6 is cut to present two branches 15 and 16 with lateral tabs 17 and 18 folded opposite one another in order to form a member for the connection of an insulated flexible conductor says: "insulation displacement".
  • the part 8 has two tongues 22 and 23, the tongue 22 being intended to serve as a guide for the electrical conductor and the tongue 23 to constitute a crimping lug for fixing said conductor.
  • the intermediate portion of the male contact member between the parts 13 and 6 is reinforced by a rib 19.
  • the portion located between the parts 6 and 8 is reinforced by a rib 21.
  • branches 15 and 16 have stamped 25 to avoid the separation of the branches and stiffen them during the establishment of the conductor.
  • the bar 5 is axially offset then, during the shaping of the member, folded in the direction of the wing 11, and finally folded to extend axially.
  • This arrangement allows an appreciable gain in material when cutting said members from the blank 1 (see fig. 2).
  • the bar 5 and a portion 13a of the part 13 have a section which corresponds to the thickness of the central strip 2, while the rest of the member has a thickness corresponding to the thickness of the lateral strips 3 and 4.
  • the two lateral faces of the bar 5 are no longer coated. It will be noted that the non-tinned faces, when the connection member is finished correspond to the upper and lower faces, while the other two faces which are the faces which must cooperate with a corresponding female member are always coated. This ensures good electrical contact.
  • FIG. 5 shows a variant of a male electrical contact member.
  • This member has a bar 25 which is produced in the strip 2 and which constitutes an extension of the core 26 of a body 34 pierced with a hole 33 and having two wings 27 and 28 and crimping lugs 29, 30, 31 and 32, the body 34 being cut from one of the lateral bands 3 or 4. The part of the core 26 and the wings 27 and 28 adjacent to the bar 25 are also cut from the band 2.
  • FIG. 6 also shows an alternative embodiment in which the male electrical contact member comprises a body 41 folded in a U to present a core 36 and two wings 37 and 38, the core 36 being extended on one side by a bar 35, while on the other side it is extended by an insulating displacement connecting member 39 having two slots 42 whose width is less than the diameter of the core of an insulated conductor to be connected so that the introduction in the slots 42 shears the insulation so that the electrical connection is ensured.
  • the body 41 is terminated by two crimping lugs 40 intended to grip the conductor to secure it.
  • the bar 35 and the part of the core 36 and the wings 37 and 38 adjacent to said bar 35 are cut from the strip 2 and the body from one of the strips 3 or 4.
  • Figures 7 to 11 also show a variant of the invention in which the male member is produced by. cutting, two by two arranged head to tail, of two bodies 50 in a blank 1a comprising a thick central strip 2a and two thin marginal strips 3a and 4a.
  • Each body 50 comprises a bar 51, a part 52 intended to be folded in a U to present two wings 60 and 61 and a core 53, the wings 60 and 61 as well as the bar 51 being cut in the strip 2a, while the extensions 54 and 55 of said wings are cut in the marginal strip 3a or 4a.
  • the core 53 has a thick part situated between the wings 60 and 61 and a thinner part situated between the extensions 54 and 55.
  • a slot 62 which extends to the right of the edge of the bar 51 adjacent to the wing 61.
  • the bar 51 is folded along its axis so (see fig. 9 and fig. 10) that it comes to be situated substantially in the longitudinal axis of the body 50 between the wings 60 and 61 against the bottom of the core 53.
