Definitions

  • Support sleeve system method for assembling a support sleeve system, method for assembling a cable gland, cable and cable gland
  • the invention relates to a support sleeve system, a method for assembling a support sleeve system, a method for assembling a cable gland, a cable with a support sleeve system and a cable gland.
  • CH 690 809 A5 discloses a connection element for shielded conductors with a conical clamping sleeve that is arranged under a cable armor. When screwing an end fitting part with a ring nut, the cable armor is clamped between a ring element of the end fitting part and the conical clamping sleeve.
  • the disadvantage of the contacts known from the prior art is that they are difficult to assemble and cannot be used multiple times.
  • the cable armouring is usually damaged when the cable armouring is jammed.
  • the clamping sleeves known from the prior art can also be lost. Particularly in the case of a new assembly, the clamping sleeve can be lost when dismantling the screw connection.
  • the object of the invention is therefore to provide an improved support sleeve system for use as a counter bearing and/or contact surface for electrical contacting of a cable reinforcement.
  • a support sleeve system for use as a counter bearing and/or contact surface for electrical contacting of a cable reinforcement at least comprising a fixing means and a support means, wherein the support means can be arranged under the cable reinforcement and the fixing means can be applied to fix the support means at least on an end section of the cable reinforcement.
  • the object is achieved according to the invention by means of a cable with an above-mentioned support sleeve system, wherein a support means of the support sleeve system is at least partially arranged under a stripped cable reinforcement of the cable and wherein an end section of the cable reinforcement is arranged in a fixing means of the support sleeve system and is fixed by means of the fixing means.
  • the object is achieved according to the invention by means of a cable gland with an above-mentioned cable with a support sleeve system, with at least one contact element of the cable gland contacting a cable reinforcement of the cable and/or a support sleeve system.
  • a support sleeve system preferably pre-assembled on a cable, is proposed for use as a counter bearing and/or contact surface for electrical contacting of a cable reinforcement.
  • the support sleeve system comprises at least one fixing means and one support means, the support means can be arranged under the cable reinforcement and the fixing means for fixing the support means can be applied to at least one end section of the cable reinforcement.
  • the support sleeve system is described in an unassembled state.
  • the advantage of the proposed support means system is that an outer diameter of the cable reinforcement of a cable arranged around the support means can be defined in a defined manner, so that the contacting properties can be designed to be the same for different cables with the same support means or the same support sleeve system. It is particularly advantageous that the support sleeve system can be pre-assembled on the cable. This means that the cable with a pre-assembled support sleeve system can easily be provided with a cable gland, for example. If the cable gland is removed from the cable, the reinforcement is protected by the support sleeve system. Reassembly into a cable gland, even of a different design, is possible, in particular with the same contact properties of the cable reinforcement and/or the support sleeve system. Contacting properties are, for example, an outer diameter of the cable reinforcement, a conductivity and/or a material hardness of the support means and/or fixing means designed as a counter bearing.
  • the support sleeve system includes a fixing agent.
  • a radial force that is essentially uniform over a circumference of the cable reinforcement can be applied to the cable reinforcement by means of the fixing means.
  • cable reinforcement and support means more preferably cable and support sleeve system, can be fixed by means of the fixing means in such a way that cable reinforcement and support means or support means system and cable cannot be moved relative to one another.
  • the fixing means is preferably a means for radially fixing the cable reinforcement with the support means.
  • the cable reinforcement can preferably only be fixed to the support means by means of the fixing means.

  • the support sleeve system can be attached to the cable independently of, for example, a cable gland by means of the fixing means. More preferably, the support sleeve system can preferably be permanently attached to the cable by means of the fixing means.
  • “permanent” is to be understood as meaning that the support sleeve system can be arranged on the cable in a substantially captive manner.
  • a permanent arrangement of the support sleeve system on the cable is preferably designed in such a way that at least the fixing means must be destroyed in order to detach the support sleeve system from the cable.
  • the fixing means is designed as a crimp sleeve or snap ring.
  • the snap ring includes a resilient, slotted sleeve.
  • the fixing means is designed as a shrink tube, adhesive tape, cable tie or similar.
  • a shrink tube is advantageously a cost-effective design, by means of which the cable reinforcement can be arranged, preferably permanently, on the support means.
  • the fixing means is preferably designed as a crimping sleeve.
  • a fixing means designed as a crimping sleeve has the advantage that the support sleeve system can be permanently attached to the cable.

  • Squeezing in the sense of the invention is understood to mean a plastic deformation that is generated by a preferably radial pressure on the part to be crushed.
  • crimping is understood to mean crimping, whereby parts are joined to one another, preferably in a force-fitting and/or form-fitting manner, by means of plastic deformation.

  • the fixing agent preferably comprises an electrically conductive material, for example a metallic material.
  • an electrically conductive material is that the fixing means can be contacted, in particular for the derivation of electrical currents, for example from a contact element of a cable gland. Furthermore, an enlarged, defined contact area is advantageously created in this way, compared to an embodiment in which only the cable armor can be electrically contacted.
  • the fixing agent which is preferably designed as a shrink tube, comprises at least one material selected from a group comprising thermoplastic elastomers, poleolefins, polyvinyl chloride, polytetrafluoroethylene, Ethylene-propylene-diene rubber and/or polymides.

  • the contact force preferably remains essentially the same over the service life of a contact element, for example a cable gland, connected to the cable that has the support sleeve system. Further advantageously, the contact between the contact element and the cable reinforcement along the support sleeve has the same contact properties. This creates a large tolerance range in which the contact element can contact the cable armor.
  • the support means preferably comprises an electrically conductive material, for example a metal, preferably copper, a copper alloy, steel, brass, an electrically conductive plastic and/or Bronze.
  • an electrically conductive material for example a metal, preferably copper, a copper alloy, steel, brass, an electrically conductive plastic and/or Bronze.
