Definitions

  • the invention relates to a support tube for a cold-shrink sleeve for joining electric cables.
  • two circular-section cylindrical support tubes made of plastics material, e.g. polypropylene, and covered in a cold-shrink elastomer sleeve, are placed end to end over the connection, and then the support tubes are withdrawn by being pulled away and by being broken on either side of the joint, with the sleeve shrinking to cover intimately the connection together with the ends of the cables.
  • plastics material e.g. polypropylene
  • the two half-tubes are injection molded, and because of mold shrinkage the half-tubes are not perfectly cylindrical. They are deformed, and as a result their mutual engagement in the vicinity of the welds is not perfect.
  • the tube tends to deform under the pressure exerted by the sleeve.
  • the half-tubes are not connected together, and as a result there is relative displacement between the half-tubes, which is accompanied by effects of warping, gaping, and ovalizing of the resulting support tube.
  • the welding leads to beads on the inside of the tube that come into contact with, and catch on, the parts located inside the tube when it is installed on the cables and the connection between.
  • Ultrasound welding is an operation that is expensive in terms of labor and maintenance, and it is also very noisy.
  • Such a support tube is held in its closed position solely by the radial pressure exerted by the shrink sleeve, once it has been placed on the tube.
  • the method of fabricating and mounting the shrink sleeve on the support tube is complex since it is necessary to use external tooling of the circular band type in order to hold the support tube closed while the sleeve is being put into place thereon.
  • the invention solves this problem, and to do this the invention provides a shrink-sleeve support tube for supporting, in an expanded state, a sleeve for an electric cable joint, and then for being removed so as to allow the sleeve to shrink onto the joint, the support tube being constituted by an open tube, and the open tube is fitted on its two longitudinal edges with mutual engagement means.
  • the engagement means serve firstly to make it easy to close the support tube, and secondly they enable the support tube to be broken in regular manner at the end of assembling the joint.
  • said engagement means are distributed regularly along said longitudinal edges.
  • said engagement means are constituted by snap-fastening teeth.
  • said longitudinal edges are constituted by mutual engagement tongues of thickness substantially equal to half the total thickness of the tube.
  • said mutual engagement tongues on an edge alternate between being internal tongues and external tongues.
  • said snap-fastening teeth are disposed on the contacting faces of some of said tongues.
  • FIGS. 1A to 1 E are face, section, and perspective views of a support tube in accordance with the invention in the open position.
  • FIGS. 2A to 2 E are face, section, and perspective views of a support tube in accordance with the invention in the assembled position.
  • the figures thus show a support tube 1 for supporting a shrink sleeve for an electric cable joint, the tube serving to support a sleeve while it is in an expanded state and then to be removed so as to allow the sleeve to shrink onto the joint.
  • the tube is constituted by an open tube fitted along its two longitudinal edges with mutual engagement means.
  • FIGS. 1A to 1 D show the support tube when open, in the form it presents on leaving an injection mold. It is made of a plastics material, e.g. polypropylene.
  • the engagement means are regularly distributed along the longitudinal edges that are designed to be in alignment and connected together. These two longitudinal edges are constituted by engagement tongues of thickness equal substantially to half the total thickness of the tube, the engagement tongues along any one edge alternating between tongues that are internal and tongues that are external.
  • edge 2 it has a series of tongues, with every other tongue being internal such as the tongues referenced 2 B and 2 D, while the remaining tongues are external, such as the tongues referenced 2 A, 2 C, and 2 E.
  • the other edge 3 is made in the same manner but with the tongues being in the opposite positions, so as to enable the tongues on the two edges 2 and 3 to engage mutually when these two edges are brought into alignment and pressed against each other.
  • the tongues are all identical in length. However, advantageously, by making the engagement tongues of different lengths, it is possible to adjust the holding force of the tube, and this is beneficial when tearing the tube away from the conductor.
  • a certain number of tongues are provided with engagement means constituted by snap-fastening teeth 20 , 30 disposed on the contacting faces of some of the tongues 2 C, 3 C. These engagement means are disposed along the total length of the tube 1 .
  • the support tube 1 is closed as shown in FIGS. 2A to 2 E.
  • the facing tongues on the two edges 2 and 3 engage mutually one on another and the tongues 2 C, 3 C carrying the snap-fastening teeth catch one on the other.
  • the support tube 1 is then ready to be used as a support for a shrink sleeve for an electric cable joint, the sleeve being placed in an expanded state on the support tube 1 which is then placed over a joint from which it is removed by being pulled away and broken, so as to enable the sleeve to shrink onto the joint.
  • the tube in accordance with the invention can be clipped together directly on leaving its mold by a robot or some other automatic means, thereby protecting the snap-fastening teeth and the mutual engagement tongues during transport, and thus avoiding an additional station for closing the tube.
