  • Figure 6 is a sectional view along line 6-6 of Figure 7 of an alternative embodiment.
  • Figure 7 is a sectional view along line 7-7 of Figure 6.
  • the housing element of FIGS. 1 to 4 is intended to receive a series of male electrical connection members 1 of the displacement type of insulation and fixed on conductors 2 in the form of a sheet 3 of flexible material and insulator in which said conductors 2 are embedded in parallel.
  • the conductors 2 are inserted into slots 5 of bars 7 which ensure the shearing of the insulation and the electrical connection, said conductors being held by a tab 6 cut from one of the bars and folded against said conductor.
  • the members 1 end with a flat tongue 9 pierced with a hole 4 and intended to be inserted into a clamp of a corresponding female member.
  • the housing element 10 consists of a body of insulating material having at one end a skirt 11, while its other end is extended by a U-shaped section part 20 with two side walls 21 and 22, this part 20 being divided into a series of compartments 12.
  • the compartment 12 located in the vicinity of the wall 21 is delimited by the latter and a partition 23, while the intermediate compartment 12 is delimited by a partition 23 a and that adjacent to the wall 22 by a partition 23 b .
  • the side walls 21 and 22 at their free end facing the inside of the housing element have a flange 13, the same flange 13 being provided along the free edge of each partition 23, 23 a and 23 b .
  • each compartment 12 is terminated, on the side of the skirt 11, by an elastic tab 14 provided with a ramp 15 terminated by a steep 16.
  • the projection 17 is pierced with a series of slots 19 intended to be crossed by the tongues 9.
  • the housing element 10 is intended to receive, engaged in its skirt 11, an additional element having a skirt intended to receive the projection 17 and to compress the seal 18 to make a sealed connection.
  • the wall 21 has, on the side of its free end, on its free edge, a recess 26 in which a notch 27 is made.
  • the partition 23 adjacent to the wall 21 has on its free edge, in the vicinity of its free end, a recess 28, while the other two partitions 23 a and 23 b are each provided with a notch 30, said partition 23 b , along its free edge having an extension 35.
  • the wall 22 has a notch 31 and a slot 34 formed in an extension 36, an extension which is connected to an extension 37 of the bottoms 24. Under the extension 37 extends a housing 32 whose part facing the wall 21 comprises a hook 33.
  • the housing element 10 is completed by a key 40 having two cheeks 41 and 42 forming an angle straight between them, the cheek 42 at its free edge comprising a tab 43 terminated by a hook 44.
  • the cheek 42 has a slot 45 which determines an elastic clamp 46 with two branches 47 and 48, the free ends of the branches being terminated by tenons 49 and 50 respectively.
  • the slot 45 has a narrow part corresponding to the thickness of the conductors 2 of small section and an enlarged part corresponding to the conductors 2 of larger section.
  • the wall 21 has a length slightly less than that of the wall 22, the difference corresponding to the thickness of the cheek 42.
  • the cheek 41 along its free edge has a tab 52 terminated by a hook 53 and a wide opening 58, the depth of which corresponds to the distance separating the wall 22 from the partition 23.
  • the cheek 41 at its end opposite to that provided with the hook 53 is provided with a lug 54, while its part adjacent to the branch 48 has a recess 55.
  • the members 1 are placed first in the compartments 12, the conductors 2, the ply 3 of which is cut at the corresponding end, are fixed to the said members 1 in the said compartments.
  • the key 40 is then put in place, the conductors coming to be housed in the slot 45 while the pins 49 and 50 are inserted in the slot 34, the hook 44 cooperating with the hook 33, the hook 53 with the notch 31 and the lug 54 are inserted into the notch 27.
  • the free edge of the cheek 41 bears against these recesses 26 and 28, while the extension 35 is placed against the offset 55.
  • the extension 36 has a length corresponding to the thickness of the cheek 42 and the extension 37 abuts against the bottom of the slot formed between the tab 43 and the corresponding edge of the cheek 42 to form a stop.
  • connection members 1 cannot be torn off untimely by a pull carried out on the ply 3, the latter also being retained.
  • the ply 3 is fixed between the branches 47 and 48, the members 1 are retained by the said branches 47 and 48 and by the tab 52 which comes to be located above the tab 6.
  • the length of the slot 34 is very slightly less than the spacing of the pins 49 and 50 so that when they are inserted into said slot the branches are close to each other.
  • FIGS 6 and 7 show in section a housing element 60 which is intended to receive a key 40 quine will not be described in detail since it is identical to that shown on the housing element 10, the housing element 60 being , in this example, intended to receive female electrical connection members 61 having at one end two elastic bars 64 and 65 constituting a clamp intended to enclose a male tongue such as the tongue 9.
  • the member 60 is arranged the same way as the device 1 with means for connecting insulation displacement 5a and a lug 6 has to be folded over the driver.
  • the member 61 is provided with an opening 66.
  • the housing element 60 comprises a skirt 70 intended to receive a corresponding male housing element and extended by lugs 71 for locking.
  • the housing element 60 On the side opposite the skirt 70 the housing element 60 comprises a U-shaped part 72 with a bottom 73 and two side walls 74 and 75, the bottom being divided into compartments 76 by partitions 77, 77 a and 77 b , each compartment 76 being intended to receive a connection member 61.
  • the compartments 76 are each extended by a conduit 79 pierced with a slot 78 and extended in the compartment by an elastic tab 80 provided with a steep 81.
  • the members 61 are inserted in the compartments 76 so that the clamps 62 are housed in the conduits 79, while the abrupt 81 comes to cooperate with the edge of the opening 66.
