  • the skirt of the second element of the second housing part has at least one inclined surface so that when the first element is introduced into the second element the elastic tabs tend to be urged towards the male connection members.
  • a perfect male connection locking is achieved in the corresponding channel of the first element of the second housing part.
  • each male connection member is produced from a metal strip suitably cut to present, at one end, crimping lugs and, at the other end, a rectangular part, between these two parts extending two side bands, the rectangular part being rolled up to form the bar, while the side bands are folded outside to form the collar.

  • Element 2 consists of a molded plastic body comprising four side walls 12, 14, 15 and 16 and a bottom 13.
  • the bead 9 extends an elastic strip 19 on which a latch 20 and a button 22 are shaped.
  • Each channel 7 comprises an opening 26 intended for the introduction of the member 3 and at its other end an opening 27 to allow the passage of the corresponding male connection member 6.
  • each channel 7 is arranged on an internal wall a projection 23 comprising on the side of the introduction opening a ramp 23a and on the other side a steep 23b.
  • the opening 27 is bordered by two stops 24, the free ends of which are in the shape of an arc and arranged on a circle having a diameter substantially corresponding to that of the male member 6.
  • slots 31 are formed which determine elastic tabs 29, these having on their external face a longitudinal rib 30 and on their internal face a projection 33 shaped to present on the side of the opening 26 a ramp 33a and on the side of the opening 27 a steep 33b.
  • the steep 33b and 23b are located in the same plane perpendicular to the longitudinal axis of the channels 7 and at a certain distance from the stops 24.
  • the female connection member 3 is shown in detail in FIGS. 9 to 12 and is produced from a metal plate which is good conductor of electricity and has a certain elasticity.
  • the member 3 is cut to present two crimping tabs 42 of an electrical conductor, two crimping tabs 43 of the insulating sheath of the electrical conductor, an elongated rectangular part 50 of which a small side 47 opposite to the crimping tabs 43 is slightly flared.
  • an opening 49 is made in which a blade 40 provided with a boss 48 extends, said part 50 comprising longitudinal stampings 41, and the blade 40 being bent at its end 46.
  • the female connection member 3 (see FIGS. 10, 11 and 12) is produced by folding the end 47 outwards to form a flange 51. The assembly is then rolled (see FIG. 12) in order to form a conduit. 52.
  • the arched part 46 comes to bear against the collar 51 so that the blade 40 is slightly projecting in the duct 52.
  • connection member 3 receives a conductor 55 which is crimped between the tabs 42 and whose insulating sheath 56 is enser ree between the legs 43, said member being engaged in a channel 7 so that the flange 51 comes to bear against the stops 24, while the steep 23b and 33b cooperate with the end 47.
  • the female connection members 3 are held in the channels 7.
  • the housing element 1 is then engaged in the housing element 2 until the pins 10 are inserted into the holes 18.
  • the engagement of the pins 10 is carried out by means of a slight elastic deformation of the housing elements 1 and 2 and is facilitated by the inclined ramps 10a. When the lugs are locked the two housing elements 1 and 2 can no longer be separated.
  • the rib 30 of the legs 29 can have a height such that when the element 1 is engaged in the element 2 the legs 29 are urged to be moved in the direction of the walls provided with the projections 23 so that the members 3 are perfectly locked in channels 7.
  • small slots or openings 53 can be provided.
  • the housing element 5 is formed by a molded plastic body having a series of channels 60 each intended to receive a male member 6, each channel 60 comprising an opening 61 for introducing the member 6 and a wall d end 63 pierced with a hole 62 through which said member 6 is inserted.
  • Each channel 60 has an opening 64 in the vicinity of the end wall 63 and said housing element 5 is produced in order to present for each channel 60 an elastic tab 65 whose free end has a projection 66 on its internal face with a inclined ramp 66a and an abrupt 66b. Opposite each elastic tab 65, a projection 67 is provided.
  • the housing element 5 on two opposite sides is provided with a lug 68 with a ramp 68a and a steep 68b.
  • the male electrical connection member 6 is shown in detail in FIGS. 14 to 17.
  • This member is made from a metal strip, good conductor of electricity and cut to present a rectangular end portion 71, one end 75 of which has an edge cut out with slots 76, while the other end has two lateral strips 72, crimping lugs 73 and 74 being provided after the side bands 72.
  • the member is made by rolling the part 71 in order to obtain a cylindrical bar with a rounded free end.
  • the lateral bands 72 are folded back outside the bar to form a collar 78, one end of which is slightly flared.
  • a conductor 80 Between the legs 73 is crimped a conductor 80, the sheath 81 of which is clamped between the legs 74.
  • the member 6 is engaged in a corresponding channel 60 and passes through its end portion the hole 62 and abuts against the end wall 63 , by the corresponding end of the collar 78, while the other flared end of the latter is retained by the abrupt 66b of the projection 66.
  • polarization means so that the housing element 5 cannot be engaged in the skirt 96 only in a determined position.
  • the housing element 4 (see FIGS. 1, 6 and 7) comprises an internal partition 84 pierced with holes 85 intended to be traversed by the end parts of the male members 6, on one side of this partition extending a skirt 86 whose internal dimensions correspond to the external dimensions of the element 5.
  • This skirt 86 has two opposite sides 90 provided with holes 87 corresponding to the lugs 68, while the other two sides 91 have a slightly narrower part 92, adjacent to the partition 84 and corresponding to the parts of the element 5 provided with the openings 64. The sides 91 widen towards the free end of the skirt 86.
  • the housing element 4 On the side opposite to the skirt 86, the housing element 4 is extended by a skirt 95 whose internal dimensions correspond to the external dimensions of the element 2 so as to receive the latter.
  • the skirt 95 is provided on a wall 96 with a hole 97 intended to receive the latch 20.
  • polarizing means so that the elements 2 and 4 can only be assembled in one position.
  • the connector can easily be opened, it suffices to press the button 22 to release the lock 20 from the opening 97, the elements 2 and 4 can thus be separated.
  • the blade 40 and the stampings 41 form protruding parts inside the duct of the female member 3, so that the male member 6 engages slightly by force and thus we are assured of good electrical connection.
