Definitions

  • Patent FR-A-2,541,049 relates to a device of this kind, characterized in that the tubular connection element has a first split end part whose external transverse dimensions are such that it can penetrate into the second split end part of another tubular connection element, similar to the first, guide means being provided between at least one interior part of the insulating support, and each tubular connection element that it supports, to allow relative movement, axial but not angular , between the insulating support and each tubular element, displacement means being provided, individually for each tubular connection element, to ensure by this relative axial displacement, the connection, respectively the connection and the disconnection, between at least one of the two transverse slots of the latter, slot which extends through the two opposite thereof, and at least one conductor dis placed in the corresponding passage which extends transversely to the insulating support in the extension of each of the two ends of the transverse slot.
  • the devices of this type described and represented in patent FR-A-2,541,049 are generally equipped with an operating member, such as a screw, by tubular connection element, or by stacking of tubular connection elements inserted. into each other.
  • an operating member such as a screw
  • tubular connection element or by stacking of tubular connection elements inserted. into each other.
  • connection device overcomes these drawbacks. It is characterized in that it comprises two identical and parallel tubular connection elements, or two parallel and identical stacks of nesting tubular connection elements, both having a common insulating support, said common insulating support being constituted by a half lower sleeve mounted on a common electrically conductive base connected to the earth of the installation, and an insulating upper half-sleeve covering the two parallel tubular elements, or the two parallel stacks of nesting tubular elements, this upper half-sleeve being traversed , parallel to the two tubular elements or tubular stacks, and between them, by an electrically conductive screw, arranged so as to be able, by coming to be screwed into a corresponding threaded orifice of said common conductive base, ensuring the bringing together of said upper and lower half-sockets.
  • Each of the modules 1,2,3 shown differs from the modules described in patent FR-A-2,541,049 by the fact that it is always double, that is to say that it comprises two devices according to the patent FR-A-2.541.049 parallel and coupled, that its lower insulating support is constituted by a double piece 8, intended to receive the two lower wires, which is fixed on a common metal bar 9, or metal base, connected to earth of the installation, and that the displacement means making it possible, by respective approximation of the upper half-socket 4 and the lower half-socket 8, to tighten the module and thereby ensure the insulation displacement connection of the lower wires and / or higher, is made up by a metal screw 10 crossing from top to bottom the central part of the module, between the two parallel tubular elements and the two parallel stacks of nesting tubular elements, to be screwed into the metal base 9 and thereby ensure the tightening vertical of the different half-sockets 4,8 or 4,5,8, or 4,6,8 constituting the module 1,2 or
  • FIG. 2 represents the simplest module 1, as it is delivered to the user before any assembly of wires.
  • the common insulating half-sleeve 4 which covers the entire module and receives the head of the central metal screw 10, the latter being screwed into the metal bar 9 to ensure the tightening of the cover 4 against the lower insulating half-sleeve 8, the latter being mounted, by fixing members 11 which are difficult to remove, on the bar 9 as shown.
  • the upper half-sleeve 4 obviously includes two tubular channels 12, 13 intended to receive the two upper wires to be connected, and likewise the lower half-sleeve 8 comprises two tubular channels 14, 15 intended to receive the two lower wires 16, 17 to connect.
  • the module 1 is equipped with two insulating connection tubular elements 18,19, split at the bottom and at the top as described in patent FR-A-2,541,049 in alignment with the tubular channels 12 to 15.
  • these tubular elements 18, 19 are parallel and intimately coupled by the fact that on the one hand their lower half-socket 8 is common and double, and that on the other hand their upper half-socket 4 is also common, double, and provided of a single central operating member constituted by the metal screw 10 ensuring not only the tightening, but also the ground connection separating the two tubular connection elements 18 and 19.
  • the module is delivered equipped with two annular shims 20 and 21 allowing the two tubular elements 18 and 19 to be held in the high position as shown, and thereby avoiding accidental crimping of the lower split part of the elements 18 and 19 on the two axial and protruding central parts 22 of the lower half-sleeve 8.
  • the non-threaded upper part 23 of the screw 20 is held in the half - upper sleeve 4 using a metal sleeve 24, crimped on the part 23, free to rotate in the half-sleeve 4 and forming a shoulder 25 opposing the withdrawal of the screw 10, as can be clearly seen in the drawing.
  • the clamping screw 10 is completely unscrewed, which first of all causes the spacing of the upper half-bush 4 relative to the lower half-bush 8 then, the screw 10 being completely removed from the bar 9, which allows manual separation of the half-sockets 4 and 8, in their relative position in FIG. 4.
  • the screw 10 is then unscrewed again, which again makes it possible to separate the upper part 4 from the lower part 8.
  • the two upper wires 26, 27 are then introduced into the two channels 12, 13. The respective positions and situations are then at this stage exactly those shown in FIG. 4.
  • the cap 4 is then again placed on the lower part 8, and the screw 10 is fully screwed into the metal bar 9 which ensures the insulation displacement connection of the upper wires 26, 27 in the upper slots of the tubular elements 18 and 19.
  • the situation obtained is then that shown in FIG. 6.
  • the module 1 therefore allows the disconnection of the upper wires 26, 27 but not the disengaging, or cutting, of this set of upper wires, disengaging which can only be achieved by the uncoupling of two nesting tubular elements.
  • the simple module 1 differs from the cut-off module 2 mainly by the fact that it is added on the module 2 a " intermediate "half-sleeve 5" comprising two additional insulating tubular elements 28,29, the upper split parts of which are intended to receive the two upper wires 26,27 and the lower split parts of which are intended to be inserted in the upper split parts tubular elements 18 and 19, thus ensuring the possibility of disengaging, or cut desired.
  • the module 2 is, on delivery, equipped with the same shims 20, 21 as the module 1.
  • module 2 is delivered with its shims 20 and 21. We therefore begin, to remove these shims, to unscrew the screw 10 until its threaded end comes to escape from the bar 9, the screw 10 then rotating in a vacuum. We then manually pull the set of two half-sockets or rings 1.5, to separate them from the lower ring 8, fixed in position on the bar 9. We remove and discard the two shims 20 and 21. We engage as for in the case of module 1, the two lower wires 16.17 in the two parallel guns 14.15 of the lower stage 8.
  • the screw 10 is then unscrewed again and the assembly 1.5 is again detached manually from the lower stage 8.
  • Figure 8 shows a variant of the screw 10 of Figure 7, avoiding to provide a lower slot 37 for screwing against the direction.
  • the screw 10 is continuously pushed upwards by a spring 40 pressing on the upper part of the nut 31, so that it comes, when it escapes from the bar 9, immediately engaged on the thread of the nut 31.
  • the module 3 of FIG. 1 differs from module 2 by the fact that its intermediate stage 6, if it is identical to stage 5 as regards its part located in alignment axial with stages 4 and 8, has a large lateral extension 7, of parallelepipedal shape, provided with a removable inspection cover 41, and containing a surge arrester 42.
  • the surge arrester, or surge arrester 42 has its two terminals 43, 44 plugged into the aligned slots, respectively upper and lower, of the elements 28.18 for the first terminal 43 and 29.19 for the second terminal 44, and has its earth terminal 45 coming to bear firmly against the body of the screw 10.
  • the housing 7 containing the arrester 42 is integrally molded with the body of the intermediate half-sleeve 6.
  • this housing 7 can be independent of the body 6, and it is detachably plugged into this body 6 for example by the terminals 43, 44, and possibly 45, or else the housing 7 does not exist at all and it is the arrester itself which is detachably plugged onto this body 6 by means of the terminals 43,44, and possibly 45.
