Definitions

  • the invention relates to electrical connectors of the so-called “hermaphrodite” type, that is to say made up of two identical housing elements turned upside down, turned upside down and nested one inside the other, each housing element comprising a series of channels intended to each receive an electrical contact member each connected to a conductor, the electrical contact members being complementary so that those of one of the housing elements coincide with those of the other and vice versa.
  • Connectors of this type are known for example from documents FR-A-2 269 807 and FR-A-2 535910.
  • One of the aims of the present invention is to remedy these various drawbacks.
  • the connector according to the invention is of the so-called “hermaphrodite” type comprising two identical housing elements, one of which is turned upside down with respect to the first, each element comprising a male part intended to be inserted in a female part of the other element and a female part intended to receive the male part of said other element, the male part being delimited by two side walls and two other walls, while the female part is delimited by two side walls and two other walls , each of the male and female parts comprising a series of channels intended to each receive an electrical contact member connected to an electrical conductor, said electrical contact members housed in the channels of the male parts being complementary to those housed in the channels of the female parts , and locking means being provided to keep said housing elements assembled, and the improvements being character sés in that the female part of each housing element has on the side walls of the slides while the male part of each housing element has on its side walls protruding bars intended to cooperate with the slides each bar being provided, to its free end of an inclined ramp, the wall of the male part opposite to that adjacent to the
  • the male part comprises a housing in which the elastic locking tab extends.
  • the elastic locking tab has an intermediate slot in which the lug is inserted in the locked position of the two housing elements, said lug having at its end turned towards the inside of the element, a steep and on the opposite side a rounded part, while the elastic locking tab is terminated by a boss.
  • the electrical contact members are of the type, known per se "hermaphrodite", and formed of a body provided at one end with means for its attachment to an electrical conductor, said body affecting a rectangular section with a floor wall provided of an extension folded inwards and terminated by an elastic tongue facing the extension.
  • a housing and a hermaphroditic electrical contact member is shown, that is to say that these elements are intended to cooperate with identical elements, but the invention, s also applies to conventional male or female electrical contact members as well as to housings taking a male part and a corresponding female part.
  • the housing shown in Figure 1 is formed of two identical housing elements 1 and 2 which can be assembled one on the other, after one of these has been turned upside down.
  • Each housing element 1 or 2 comprises a part 22 delimited by side walls 22a and walls 22b and 22c and which constitutes the male part, the female part being referenced at 23 and being delimited by walls 23a, 23b and 23c.
  • the male part 22 has channels 3 intended to each receive an electrical contact member 4, while the part 23 has a series of channels 3a each intended to receive a contact member 4.
  • FIG 2 there is shown in perspective a member 4, this being made of a metal good conductor of electricity having a certain elasticity, said member 4 having, at one end, tabs 5 intended to enclose a sheath 6 of a conductor 8 and, tabs 7 for enclosing the corresponding stripped end of the conductor.
  • the member 4 has a floor wall 9 provided with an extension 10 folded to form an elastic tongue 11.
  • the member 4 is shaped to have two side walls 13 and 14 which are terminated by flaps 15 and 16 extending substantially parallel to the floor 9 to form a sort of conduit with rectangular section.
  • Such a member 4 can receive a simple male bar inserted between the extension 10 and the tongue 11 or be used with an identical member, the latter then being turned upside down and inserted, by its extension 10 against the extension 10 of the other member 4 and the plastic tongue 11, the extension 10 of said other member 4 being inserted in the same way between the extension 10 and the tongue 11 of the first member 4.
  • the floor wall 9 has, in the vicinity of the tabs 7, a hole 18 which is intended to cooperate with a lug 19 carried by an elastic tab 20 provided in each channel 3.
  • Each channel 3 also has a stop 17 against which the free end of the flaps 15-16 comes to bear.
  • each element 1 or 2 is provided with an elastic locking tab 25 which is integral by its end 26 with a reinforcement 30 of the wall 22c, said elastic locking tab 25 having a rigid arcuate part 27 extended by an elastic part 31 pierced with a slot 28 and terminated by a boss 29.
  • the elastic locking tab 25 is located in a housing 33 formed in a middle part of the wall 22b of each element.
  • the wall 23c comprises a lug 35 which has a rounded part 36 and a steep 37, this lug being located in the plane of the elastic locking tab 25.
  • the side walls 22a of the part 22 each have, in the vicinity of the wall 22b, a guide bar 38, the latter having an inclined ramp 40.
  • the part 23 is provided, in its side walls 23a with slides 39.
  • the slides 39 of the element 1 being intended to receive the edges 38 of the element 2 and vice versa.
  • the lug 35 is slightly set back relative to the edge of the wall 23c.
  • the electrical contact members are manufactured with the utmost care and the housings are also manufactured with great precision, especially when the elements are very small, it may happen that when the element 1 is fitted on the element 2 that the extensions 10 of two members 4 which is disposed in a channel 3 of an element and the other in the corresponding channel 3a of the other element abut against one another. In this case either, one cannot assemble the elements 1 and 2 of the housing, or, one forces and one of the organs is damaged and the electrical connection is not perfectly carried out.
  • the invention avoids improper positioning of the electrical contact members at the start of assembly and eliminates the risks of poor electrical connection between the corresponding members of two elements of complementary housings.
