  • each wing has a tab extending perpendicular to said lateral edge and folded to extend towards the outside of the U parallel to the core.
  • each wing cut in the vicinity of each lateral edge perpendicular to the core to form on each side a tab which is folded towards the outside of the U parallel to said core.
  • the device comprises an insulating housing intended to receive said device and arranged to receive the main conductor.
  • the housing comprises two identical housing elements intended to be mounted one on the other, head to tail, upside down, each element having a generally rectangular shape and comprising a central housing intended to receive the connection device, an axial cradle for the main conductor, in the vicinity of one end along two opposite sides of the legs terminated by hooks, while in the vicinity of the other end along the said two opposite sides are provided plates corresponding to said tabs and provided with openings on either side of the cradle being formed corridors for the passage of electrical contact members to be connected to the device and said element comprising elastic bars opening into the corridors and provided with pins intended to cooperate with said members.
  • the housing element comprises means for locking the elastic bars.
  • the housing element comprises a cover hinged at one end and provided with wings intended to mask notches in which extend the elastic bars, means being provided for locking said cover in the closed position.
  • the housing element comprises a cover hinged at one end and comprising means for its locking against the external face of said element, the elastic bars being cut in the corridors and comprising projecting lugs in these.
  • the cover has, in the vicinity of its free edge, a first step intended to cooperate with a shoulder provided on the element, the position of the step and the shoulder being such that the cover occupies a waiting position in which the elastic bars can be moved to allow the establishment of female electrical contact members, a second step and a second shoulder being provided to ensure a completely closed position of said cover and thus block the elastic bars to ensure the locking of the organs of female electrical contacts.
  • FIGs 1 and 2 there is shown a device produced by cutting and bending a metal strip good conductor of electricity and having a general U shape with a core 1 and two wings 2 and 4.
  • the wing 2 has a middle slot 3 which extends to the vicinity of the core 1 and which opens by flaring on the free edge of said wing 2.
  • the wing 4 is cut in the same way as the wing 2 and has a slot 5.
  • the wing 2 comprises along its edge 2 has a tab 6 folded to extend towards the outside of the U substantially parallel to the core 1.
  • the edge 2 b of the wing 2 comprises a tab 6 a disposed parallel to the tab 6.
  • the flange 4 is provided along the edges 4a and 4b of tabs, respectively, 7 and 7a.
  • Such a device allows the branch connection in particular for ground wires, an insulated ground main cable being forced into the slots 3 and 5 so that the insulation is split by the edges of the slots 3 and 5, while the female contact members connected to conductors are engaged on the legs 6, 7, 6 a , 7 a .
  • FIGS. 3 and 4 an alternative embodiment of the device is shown, which is obtained by cutting and folding a metal strip 101 folded in a U to present two wings 102 and 104 and a core 103.
  • the wings 102 and 104 have median slots, respectively 105 and 106 and which open by flaring on the free edge of said wings.
  • the wing 102 has on each side legs 107 which are folded outwards to extend substantially parallel to the core 103.
  • Two legs 108 are provided on either side of the wing 104, these legs 108 being located in the same plane as the legs 107.
  • FIGS. 5 to 12 a box is shown which consists of two identical elements arranged upside down, upside down and which is intended to receive the device of FIGS. 1 and 2.
  • Each housing element comprises a body of insulating molded plastic material which has in its central part a housing 36 intended to receive the device of FIGS. 1 and 2.
  • the body 35 On the side of one end 40 along one side, the body 35 has two elastic tabs 37 and 37 a terminated towards the outside of said body by hooks, while on the same side, but in the vicinity of the opposite end, two plates 38 and 38 a are provided with openings 41 corresponding to the hooks.
  • the other longitudinal side 46 of the body 35 also has lugs 37 and 37 a and plates 38 and 38 a with openings 41.
  • the body 35 comprises, axially on one side of the housing 36, a cradle 43 having a circular arc section and, on the other side of the housing 36 a second cradle 44 having a corresponding section.
  • the body 35 has, on the side of the end 40, flanges 50, while in the vicinity of the end opposite to the end 40, said edges 45 and 46 have lugs of guide 49, 49 a and 49 b , so that when two housing elements are presented head to tail upside down, the pins 49, 49 a and 49 b are inserted between said flanges 50.
  • the body 35 along each edge 45 and 46 between the plates 38 and 38 a , has notches 60 and 60 a which lead respectively into corridors 52 and 52 a .
  • Each of the wafers 38 has adjacent the end of the body 35 opposite the end 40 comprises an elastic strip 56 which extends into the corresponding notch 60, 60 a.
  • the elastic bars on the side facing the respective lanes 52, 52 a are provided with a lug 57.
  • the end of the body 35 opposite the end 40 is connected by a flexible strip 64 to a cover 65 which has two lateral wings 66 and, in the vicinity of the free edge of each said lateral wing, a step 67, a second step 68 being provided, in the vicinity of each wing 66, and offset in height relative to the step 67.
  • the pins 49a are provided with a shoulder 71 intended to ensure definitive locking of the lid 65 cooperating with the barbs 68, while the wafers 38, on their corresponding edge have a shoulder 70 intended to cooperate with the barbs 67 for waiting position. In this latter position the free edge of the wings 66 is located outside the elastic bars 56 so that they can play freely.
  • the device is put in place in the housing 36 so that the tabs 6a and 7a extend in the corridors 52 and 53 and the tabs 7 and 6 in the hallways 53a and 52 a .
  • the housing element with the device can be mounted on an insulated main ground conductor 73 forcibly engaged in the slots 3 and 5 so that the insulation is cut by the edges of the slots and that contact is thus made between said conductor and the device, the conductor 73 resting in the cradles 43 and 44, while the cover 65 is in the standby position, the rebates 67 cooperating with the shoulders 70.
  • a second housing element identical to the body is mounted on the first element and presented upside down so that the legs 37 and 37 a of one come by their hooks to lock the other by cooperating with openings 41 of the plates 38 , 38 a on the other.
  • This assembly is facilitated by the studs 49, 49 a and 49 b which guide, with respect to each other, the two elements until they are assembled.
  • Corridors 53, 53 a and 52, 52 a form at each end of the two assembled housing elements channels into which female electrical contact members 75 can be introduced, having at one end a conduit 77 intended to force-engage on the tongues 6 or 7 and at the other end of the crimping lugs 78 and 79 for a conductor 81, said member having a slot 76 having a dimension greater than that of the pins 57.
  • FIG. 14 a variant of the housing elements has been shown in perspective, these being intended to receive the device of FIGS. 3 and 4.
  • the housing is formed by two identical elements arranged head to tail, upside down.
  • the cover 116 is produced in the same way as the cover 65 and its lateral wings 117 have steps to occupy, by cooperating with the corresponding shoulders, a waiting position in which the bars 112 can play elastically and a locked position in which the bottom of the cover ensures their blocking.
