Definitions

  • the present invention is directed to a female electrical contact member.
  • the invention relates to an electrical contact member inserted from a blank of a good electrically conductive material, cut and folded to present, from one end, a pair of crimping tabs.
  • an electrical conductor housed in an insulating sheath, a pair of tabs intended to be crimped on a stripped end of the conductor and a body of rectangular section whose two opposite sides are extended by elastic tabs folded towards the inside of the body and intended to grip a male tongue inserted into said body.
  • An electrical contact member according to the preamble of claim 1 is known from the document FR 2 754 943 .
  • two opposite sides of the body comprise, in the vicinity of the free end thereof, an opening for receiving a lug of a resilient strip provided in a channel of an element of an electrical connector for locking of the contact member in the channel.
  • these electrical contact members have small dimensions so that a simple pull on the driver causes the pin to disengage from the opening so that the contact member may be untimely out of its channel.
  • a first type is to provide on the faces provided with openings, a light for receiving a pin carried by a flap provided on the electrical connector element.
  • Another solution consists in providing, slidingly mounted on the housing element, a key provided with fingers intended to engage the channels to cooperate with the faces of the resilient bars opposite those provided with the lugs so that they do not can no longer escape the openings.
  • One of the aims of the present invention is to overcome this disadvantage.
  • the female electrical contact member which is the subject of the invention, is of the type comprising a body of parallelepipedal general shape with four faces, two of which opposite the free end are extended by elastic tongues folded towards the inside of the body. and intended to grip a male tongue, while at its other end, the body comprises, on the one hand, a first pair of crimping tabs for gripping an electrical conductor protected by an insulating sheath and, on the other hand, a second pair of crimping tabs intended to be crimped on a stripped end of said conductor, and is characterized in that the body comprises, on at least one side, in the vicinity of the free end, an opening, the face provided with the opening and the opposite face being extended, each by a cheek, the latter going so close as to form a narrow part, at least one of the cheeks being pierced with a light.
  • the body comprises, on two opposite faces, an opening and on each of the cheeks extending the opposite faces, a light.
  • the body comprises, in each of the cheeks, on the side of the portion thereof adjacent the corresponding faces, a stamped so as to form in said cheeks projections extending to the edge of the corresponding lights.
  • a stamped so as to form in said cheeks projections extending to the edge of the corresponding lights.
  • the electrical contact member shown in the figures is made from a blank of a good electrically conducting metal, cut and folded to present a body 1 with a rectangular section with four faces 2, 3, 4 and 5.
  • the face 3 is formed by the junction of the two ends of the blank with a dovetail portion 6 inserted into a correspondingly shaped opening 7.
  • the faces 2 and 4 are each extended by an elastic tongue 8 bent inside the body 1 and intended to elastically grip a male bar inserted into said body to make the electrical connection.
  • the faces 2 and 4, on the opposite side of the tabs 8, are extended by cheeks 13 and 14 which are moving towards each other and in which are made respectively 16 and 17 lights, these cheeks 13 and 14 forming a narrow part 25.
  • each of the cheeks 13 and 14 are made embossed so as to form a projecting portion in the vicinity of the lights 16 and 17, each projecting portion forming, by its edge, a stopper.
  • the body 1 is extended by a narrow intermediate portion 21, the latter being connected to two pairs of crimping tabs 22 and 23.
  • the crimping tabs 22 are intended to grip one stripped end of an insulated conductor, while the tabs 23 are intended to grip said conductor.
  • FIG. 5 there is shown a double locking means in which the electrical contact member according to the invention can be used.
  • the electrical contact member is housed in a channel 30 of a housing member 31 of an electrical connector.
  • the channel 30 comprises an elastic strip 33 with a lug 32 intended to be inserted into one of the openings 12 to form a first lock.
  • the housing element 31 is provided with a flap 34 with a pin 35 intended, in the closed position of the flap 34, to cooperate with the corresponding light 16 and to oppose inadvertent removal of the electrical contact member, the edge of the corresponding stamp 18 abutting against the pin 35 (see figure 5 ).
  • FIG 6 shows a variant in which a connector housing element 40 comprises channels 41 in which are engaged electrical contact members according to the invention, each channel comprising an elastic strip 42 with a lug 43 intended to engage in the opening 12 corresponding.
  • a conduit 44 for receiving a key 45 which, inserted under the bar 42, opposes any tilting thereof.
  • FIG. 7 schematically shown a housing element 50 having a series of channels 51 for receiving, each, an electrical contact member according to the invention, each channel having one or two resilient bars 53 with a lug 54 for insertion into the corresponding opening 12.
  • the housing member 50 is provided with a transverse duct 56 in which a key 57 consisting of a core from which a series of parallel fingers 58 are formed can be inserted.
  • a key 57 consisting of a core from which a series of parallel fingers 58 are formed can be inserted.
  • the portion 25 of the electrical contact member is inserted between the fingers and thus said member can not be removed from the channel until the key has been removed since the edge of the sipes 18 and 19 stops against the fingers 58.
  • the electrical contact member according to the invention has no sharp edge so that it can be introduced through a hole of a joint without the risk of damaging it.
