Definitions

  • the invention relates to a device for securing an electric cable to a plug handle.
  • the base rests, with generally the interposition of a seal, on a span of the handle and the jaws are erected above the base while a frustoconical bearing is arranged in a cap. so as to ensure when fixing said cap on the handle, a clamping of the jaws on the cable.
  • the seal provides a seal between the base and the handle, while being applied, thanks to a special shape, to the cable, but the jaws remain vulnerable to bad weather and in particular to frost since they are placed at the above said seal and turned towards the cap.
  • the invention provides a device comprising in known manner a clamping part which is formed of an annular base provided with a plurality of jaws which project from said base and which are arranged so as to cooperate by elastic deformation with at least one frustoconical bearing, the device according to the invention being remarkable in that the clamping piece is arranged in the handle so that the bits, of which at least the outer parts of the ends converge opposite the base, are arranged relative to the latter on the side opposite to the arrival of the cable in the handle, while the frustoconical bearing is arranged in the handle and converges towards the longitudinal axis of the latter on the side opposite to said arrival of the cable, means being provided for exerting pressure on the base and immobilizing the latter in the handle so that this pressure causes an axial displacement of the base and jaws and therefore a tightening thereof between them on the frustoconical bearing.
  • the jaws are turned over, the base no longer rests fixedly on a bearing surface of the handle, the frustoconical bearing acting on the jaws is no longer in a movable cap but in the handle itself, so that the movement causing the clamping of the jaws is no longer that of said bearing relative to jaws in a fixed axial position, but that of movable jaws axially with respect to a fixed span.
  • the tearing-off force to be combated is effected by a force directed towards the point of convergence of the jaws when the cap is tightened while according to the invention , said force is directed on the side opposite to said point of convergence.
  • this is arranged between the base of the clamping piece and a cover which is perforated centrally to let the cable pass, the peripheral part of said seal coming into contact with the inner wall of the handle.
  • the seal is provided with a peripheral rib intended to come into contact with the internal wall of the handle.
  • the invention proposes that the cover or the base of the clamping piece be provided with pins intended to come to force fit into conjugated housings arranged in the base or respectively the cover so as to assemble and immobilize together said cover, the clamping piece and the seal which is provided with openings sealed through by said studs.
  • the cover, the base of the clamping part and the seal are provided with openings for the passage of fixing screws which engage in threaded bores formed inside the handle, the the openings of the seal being adjusted in order to ensure a seal when the screws pass.
  • the cap and the base of the clamping piece or respectively the cover have parts which come into contact before the cap is completely screwed onto the handle so that said cap exerts direct pressure on the base or respectively the cover during its screwing.
  • the frustoconical bearing surface of the handle is divided into as many frustoconical sectors as the base has jaws, each sector being delimited laterally by walls parallel to the longitudinal axis of the handle so as to position and guide said jaws.
  • FIGS. 2 to 4 show a plug handle 1 in which a mooring device (2,3,4) according to the invention is fixed, intended to secure a cable 5.
  • the mooring device as shown more particularly in FIG. 1, comprises a clamping part 2, a seal 3 and a cover 4.
  • the clamping piece 2 comprises an annular base 6 from which project four jaws 7a to 7d arranged two by two along two orthogonal radial planes.
  • the jaws 7a to 7d are attached elastically to the base 6 of the part 2 by a part of thin material.
  • the seal 3 has (FIGS. 1 to 4), a perforated central part in the form, for example, of a hyperboloid of revolution intended to conform elastically to the shape of the cable 5 to be secured (FIGS. 2 to 4), an annular flat part 8 and a peripheral part provided with a rib 9 ( Figures 1 and 2).
  • the cover 4 has an annular part 10, from which project two small studs 11a, 11b, diametrically opposite.
  • the base 6 of the clamping part 2 and the annular part 8 of the seal 3 have openings respectively 12a, 12b and 13a, 13b, positioned in the same way as the pins 11a, 11b of the cover 4.
  • annular parts 10 and 8 of the cover and ..respectively of the seal, as well as the base 6 of the part 2 have diametrically opposite openings, respectively 14a, 14b, 15a, 15b and 16a, 16b, all positioned in the same way.
  • the parts 2, 3 and 4 are intended to be assembled in the order shown in FIG. 1 to form an assembly shown in FIGS. 2 to 4.
  • the pins 11a, 11b of the cover 4 pass through the openings 13a, 13b of the seal 3 in a leaktight manner and at least in part the openings 12a, 12b of the base 6 of the part 2 into which they are forced in and s '' immobilize, said openings 12a, 12b possibly being provided with a small shoulder internal retainer.
  • the seal 3 is therefore clamped between the annular part 10 of the cover 4 and the base 6 while the openings 14a, 15a, 16a and respectively 14b, 15b, 16b are aligned.
  • FIG. 2 shows the previously described 2,3,4 mooring device ready to be fixed on the plug handle 1.
  • the plug handle 1 has tapped bores, such as that shown in 17, intended to receive screws, such as that shown in 18.
  • Figures 2 and 3 are folded sections made along two orthogonal lines, so that they represent a single bore 17 for a screw 18, which allows to represent at the same time one of the assembly pins of parts 2, 3 and 4 (in fact there are two bores 17 diametrically opposed for two screws 18).
  • the plug handle 1 also has a frusto-conical surface (19) divided into four converging frusto-conical sectors on the side opposite to the arrival of the cable and we can partially see two, 19b, 19d in FIG.
  • the frustoconical sectors arranged in the handle are each delimited on its two sides by walls parallel to the longitudinal axis of the handle, such as the walls 20b, 20d seen in part in FIG. 2 (there is therefore in the mode of realization represented four sectors and eight walls 20).
  • the device 2,3,4 is arranged in the handle 1 so that the jaws 7a to 7d are directed towards the inside of said handle.
  • each jaw 7a to 7d has a face, turned towards the longitudinal axis of the device, which is provided with ribs or notches while the opposite face is convergent towards said axis relative to in the plane of the base 6.
  • Cable 5 is threaded through the perforated central parts parts 2, 3 and 4 which are assembled and arranged in the manner previously described, the central part of the joint pressing against said cable.
  • the cable 5 is of course then connected to the various contacts (not shown), provided in the handle, and the device is then fixed by screwing by means of the screws 18 which pass through the openings 14a to 16a and 14b to 16b to engage in the threaded bores 17 of the handle.
  • the jaws are also perfectly guided during the screwing between the different walls 20.
  • Figure 4 shows an embodiment with nut fastening.
  • the parts 2, 3 and 4 are identical to those shown in FIG. 1 with the exception, however, of the openings 14a, 14b to 16a, 16b.
  • the handle 1 is provided with an external thread intended to come into engagement with an internal thread of a nut or cap 21.
  • the cap 21 is provided with an oblique internal surface intended to come into contact with the cover 4 so as to exert by screwing pressure and holding the parts 2, 3 and 4 while playing the role of the screws 18 of the embodiment described above. .
  • the fixing means 18 or 21 of the device 2,3,4, the lateral retention of the jaws by the surfaces 20 and the arrangement of the jaws ensure good maintenance of the cable 5 in the event of twisting or pulling on it.
  • the device mooring having, for example, not necessarily a seal (depending on the applications), the cap 21 of the embodiment of FIG. 4 then acting directly on the part 2.
