Definitions

  • the present invention relates to an interconnection device making it possible to electrically connect two cables to each other, each of them being formed of a metallic core surrounded by an insulating sheath, without having to strip them, comprising jaws equipped with sharp members arranged in opposition in two paired systems each of which is assigned to a respective cable, at least one of the sharp members of one of the systems being metallic and electrically connected to at least one of the sharp members , also metallic, of the other system, the sharp members of each system being able to penetrate the insulator of the corresponding cable when the jaws between which the cable has been brought together by means of clamping means been introduced, and making electrical contact with the cable core.
  • Interconnection devices of this type are known, in which the two aforementioned sharp member systems are carried by a single pair of jaws common to the two cables.
  • Such an arrangement has the disadvantage of requiring simultaneous positioning of the two cables before tightening the jaws which will ensure interconnection.
  • the jaws must be able to tilt relative to each other to accept cables of different diameter which, therefore, may not be properly gripped.
  • the present invention overcomes these drawbacks by providing, in a device of the type under consideration, two pairs of jaws, each pair comprising one of said systems of sharp members, while the means of tightening the pairs of jaws are designed to so as to allow a clamping of these pairs independently of one another, the mutual displacement travel of the jaws of each pair being rectilinear and defined by means of guiding in translation.
  • Such an interconnection device makes it possible to mount and connect each of the cables separately.
  • the tightening of each of the two pairs of jaws is carried out in a pure translational movement, without any tilting, so that the two cables can be identically gripped optimally.
  • each pair of jaws comprises a jaw fixed relative to said guide means and a movable jaw, movable along the latter.
  • each pair of jaws is provided with a snap which ensures an erasable holding of the movable jaw in a loosening position, which facilitates the handling of the device and the assembly of the cables.
  • the two fixed jaws are mutually integral and arranged back to back, the two movable jaws being arranged on either side of the set of two fixed jaws.
  • the clamping means of the jaws may comprise two independent screws, each one being assigned to a respective pair of jaws and passing through one of the jaws to be screwed into the other jaw of this pair.
  • they may include a screw common to the two pairs of jaws, which passes through the movable jaw of one of the pairs and all of the two fixed jaws to go to be screwed into the other movable jaw.
  • the snap-fastening of one of the pairs of jaws should be designed to yield, with respect to the tightening force applied by said screw, more difficult than that of the other pair of jaws.
  • the actuation of the clamping screw firstly brings the pair of jaws closer together, the latching yielding more easily, then from the other pair of jaws.
  • the snap which gives the most difficulty is designed to be able to maintain the corresponding movable jaw in two adjacent loosening positions; this arrangement maintains this movable jaw in the interval between the two operating phases where only a first cable has been mounted in the device.
  • the interconnection of the two cables is carried out in a very simple manner when at least one of the sharp members of each of the fixed jaws is metallic and these sharp members are electrically connected to each other.
  • the sharp members of each of the two pairs of jaws are produced in the form of flat teeth each situated in a plane transverse to the axial direction of the cables to be connected, preferably perpendicular to this direction, and joined in pairs, the teeth of each pair having cutting edges turned towards each other obliquely to the clamping direction of the jaws on the cable and arranged symmetrically on either side of the mediating plane of the cable parallel to this direction.
  • Figures 1 and 2 show, respectively in elevation and in plan with partial sections, an interconnection device according to the invention, in a first version.
  • FIG. 3 represents a view along arrow III of one of the movable jaws of the device of FIG. 2.
  • FIGS. 4a to 4d represent a second version of an interconnection device according to the invention, respectively illustrating four stages of the assembly of cables to be interconnected.
  • the interconnection device shown in Figures 1 and 2 comprises two pairs of jaws 1 and 2 composed respectively of a fixed jaw 1f, 2f and a movable jaw 1m, 2m.
  • Each of these jaws is equipped with flat teeth 3 which, when the jaws of a pair are clamped, penetrate by their cutting edges 20 the insulating sheath 4 of an electric cable 5, 6 placed between the jaws of this pair, until it comes into contact with the conductive core 7 of the cable , as can be seen in Figure 4b for the jaws of pair 2.
  • the fixed jaws 1f, 2f are attached back to back and fixedly attached to a main body 8 of insulating material, for example of polyester loaded with glass fibers. At least some of the teeth 3 of the fixed jaws 1f, 2f are made of metal and are connected from one jaw to the other by a conductive bar 19 intended to ensure the transfer of electric current between the cables.
  • the movable jaws 1m, 2m Faced with these fixed jaws are arranged the movable jaws 1m, 2m; these, which can be made of the same insulating material as the body 8, have a rectangular opening 9 through which each is engaged on one end of a metal bar 10 of conjugate section, integral with the body 8; this bar thus ensures the guide of the movable jaws 1m, 2m according to a rectilinear translational movement which allows them to come to grip by their flat teeth 3 the cables 5, 6, the longitudinal axes of which are parallel to each other and perpendicular to the sliding direction D joint of movable jaws 1m, 2m.
  • Each of the movable jaws 1m, 2m is assigned a specific clamping screw 11, 12.
  • the screw 11 has a head 11a which is applied to the outer face of a metal plate 1a for load recovery belonging to the jaw 1m; the barrel of this screw crosses this plate by a bore the passage where the screw can rotate freely, while its threaded end is engaged in a threaded channel 13 formed in the bar 10, from one end thereof to its other end where the screw 12 for clamping the movable jaw 2m is engaged symmetrically, identical to the screw 11 and arranged in the same way.
  • Each of the movable jaws 1m, 2m has a notch 14 in which a boss 15 can be engaged, carried by an elastic tab 16 of snap-fitting belonging to the body 8; a movable jaw is, in this situation, held in a loosening position, away from the fixed fixed jaw.
  • the flat teeth 3 fitted to the jaws are of the type described in the patent application filed the same day with the same name for a connection device. As shown, these teeth, contained in planes perpendicular to the axial direction of the cables 5, 6 are joined in pairs on each of the jaws. Their cutting edges 20, in the form of quarter circles, extend obliquely with respect to each other so as to reveal between them a curvilinear reentrant angle by which each pair of teeth 3 comes to cover the corresponding cable before d 'enter it.
  • the interconnection device described makes it possible in particular to produce a junction cable 6 on a main cable 5. Thanks to the fact that the clamping means of the jaws are constituted by two screws 11, 12 respectively assigned to one and to the other of the pairs of jaws 1, 2, these can be clamped independently on the corresponding cable. It is therefore possible to connect to the device first of all the drop cable 6, then to connect to the main cable the device already subject to the drop cable.
  • the interconnection device shown in Figures 4a to 4d has a general structure similar to that of the device previously described with reference to Figures 1 to 3.
  • the latter can move in translation, guided on the bar 10 secured to the main body 8, under the action of clamping means acting by means of the plates 1a, 2a belonging respectively jaws 1m, 2m.
  • Each of these can be locked in the release position by a snap-fastening comprising the elastic tongue 16, the boss 15 of which is capable of coming to engage in the corresponding notch 14 of the jaw.
  • the jaw tightening means comprise a single screw 21 common to the two pairs of jaws 1, 2.
  • This screw passes through a bore through the plate 1a of the movable jaw 1m, against which its head 21a is supported, then the bar 10 by a channel 23 similar to the channel 13 of the previous device, but not threaded, to engage at its end - threaded - in a threaded hole 24 that includes the plate 2a of the other movable jaw 2m .
  • a second notch 14 ′ is provided, close to the notch 14, where the boss 15 is immediately housed, restoring the maintenance of the jaw 1m in a second loosening position (FIG. 4c ) slightly closer to the corresponding fixed jaw 1f than the first loosening position defined by the notch 14.
  • the main cable 5 is put in place between the jaws of the pair 1 and the screw 21 is again actuated.
  • This brings the fixed jaw 1f closer to the movable jaw 1m, the boss 15 of its snap having escaped the second notch 14 ′.
  • the flat teeth 3 of these jaws penetrate the insulation 4 of the cable until it touches its core 7 (FIG. 4d).
  • the elastic interconnection of the cables 5 and 6 is then completed, via the flat teeth 3 conducting the fixed jaws 1f, 2f and the conducting bar 19 which connects them.
