Definitions

  • the present invention relates to a female electrical contact member intended to be placed in a housing of an insulating housing and to receive a corresponding male member constituted either by a simple tongue, or by a printed circuit.
  • the invention relates to an electrical contact member of the type formed by a body made of a material that is good conductor of electricity, cut and folded to have a substantially U-shape with at one end means for its attachment to an electrical conductor and at its other end, two elastic contact bars intended to enclose between them a male contact member, said elastic bars being protected by external tabs.
  • the elastic bars are cut out from the free edges of the outer tabs so that said elastic bars are folded inside the tabs, the folded edges then also being folded over so as to extend one by look of the other.
  • One of the aims of the present invention is to produce a contact member of the above type which is much less expensive to manufacture.
  • the female electrical contact member is of the type formed by a body made of a material which is good conductor of electricity and endowed with a certain elasticity, said body being cut and folded to take the form of a U with a core and two wings, one end of said body being shaped to present means for its attachment to an electrical conductor, while at its other end, the wings of the U are extended, on the one hand, by two contact strips intended to elastically enclose a corresponding male contact member such as a tab or printed circuit and, on the other hand, by two tabs extending on both sides of the contact strips and intended to protect them, said member being characterized in that the tongues are formed by an extension of the free edge of each contact strip, in the vicinity of the means of attachment to a electrical conductor, each said extension extending over the entire length of the corresponding contact strip and being folded to extend on the side of the external face of said corresponding strip.
  • each tab has a dimension slightly larger than the corresponding contact strip and has a flange, the flanges of the two tongues facing each other.
  • the flanges delimit the maximum thickness of the male member that can be used with the female contact member and the tongues thus have good mechanical strength.
  • the body may include between the contact bars a folded plate to extend perpendicular to the core of the U.
  • a stop is thus produced in a simple manner limiting the depth of introduction of the male organ in the female contact organ, according to the invention.
  • the plate can constitute a stop limiting the introduction of the conductor between the means for fixing the latter.
  • the plate constitutes a barrier for said insulating material.
  • the contact member shown in the figures is made of a metal strip that is good conductor of electricity and has a certain elasticity.
  • the strip is cut to present a body 1 with at one end two tabs 2 intended to be crimped onto a conductor and in the vicinity of these two tabs, two other tabs 4 intended to be crimped onto a stripped end of said conductor.
  • the body 1 On the side opposite the legs 2, the body 1 is cut to present two bars 6 and 7 and two tongues 5 and 8 extending parallel to each other and substantially parallel to the longitudinal axis of the body 1.
  • a wide opening 9 in the bottom of which is cut a plate 10 intended to constitute a stop.
  • the tongue 5 has at its free end two notches 11 and is separated from the bar 6 by a slot 12, the bottom of which forms a wider notch 13.
  • the tongue near its free end, is provided with an opening 14.
  • the tongue 8 is separated from the bar 7 by a slot 17, the bottom of which forms a wide notch 18.
  • the tongue 8 is pierced with an opening 19 in the vicinity of its free end which has two notches 20.
  • the free edge of the tongue 5 is folded to form a flange 5 a , while the part of the free end located between the two notches is folded to form a flange 5 b and the edge adjacent to slot 12 is folded to form a ledge 5 c .
  • the strip 6 is intended to form one of the contact strips and has a length and a width corresponding to the space delimited by the flanges 5 a , 5 b and 5 c .
  • the tongue 8 is identical to the tongue 5 and has flanges 8 a , 8 b and 8 c .
  • the strip 7 has the same dimensions as the strip 6 and constitutes the contact strip.
  • the body 1 is folded into a U to present a core 1 a and two wings 1 b and 1 c , while the plate 10 is folded at 90 ° so as to extend into the core of the U substantially perpendicular thereto. , the two contact strips 6 and 7 coming to be located opposite one another by extending the wings 1b and 1c and the facing faces of said strips being connected so that the free ends diverge.
  • the tongue 5 is folded along a line extending the slot 12 so as to extend on the side of the external face of the contact strip 6.
  • the tongue 8 is folded in the same way as the tongue 5 so as to extend on the side of the external face of the contact strip 7.
  • a female contact member is thus produced which offers great safety in use. In fact, when this member is inserted into a housing, the contact strips 6 and 7 are protected and do not risk being deformed. Thanks to the flanges 8 a , 8 b and 8 c and 5 a , 5 b and 5 c , a space is defined which corresponds to the thickness not to be exceeded for the male contact member to be inserted between the contact strips 6 and 7.
  • the male contact organ can be a simple tab or a printed circuit and said male contact member can be inserted between the contact strips 6 and 7 in the axis of the female contact member, according to the invention, as well as by tilting, pivoting Or other. Finally, such a female contact member can easily be locked in a housing of a housing, the latter comprising projections or stops cooperating with the openings 14, the flanges 8b , 5b or the notches 13 and 18.
