Definitions

  • the present invention relates to a fixing sleeve for optical cables
  • the invention finds a particularly advantageous application in the field of interior wiring of buildings by optical cables.
  • optical cables are generally mounted free inside the tubes so that they are particularly exposed to various stresses, such as pulls or bends at the outlet of the tubes. These stresses are most often generated by handling the cables during a connection operation for example and risk causing them seriously damage if they exceed a maximum limit value, in particular with regard to the radius of curvature of the cables
  • the technical problem to be solved by the object of the present invention is to propose a fixing sleeve for optical cables which would, on the one hand, immobilize the cables in order to avoid harmful tensile movements, and, on the other hand to limit their bending to a minimum radius of curvature
  • the solution to the technical problem posed consists, according to the present invention, in that said sleeve comprises, along a same axis, a first substantially cylindrical portion and a second substantially conical portion, said first and second portions being pierced by a hole axial and in that the sleeve carries over its entire length a continuous slot communicating with said axial hole, formed by a first longitudinal slot in the first portion of the sleeve and a second spiral slot in the second portion of the sleeve
  • the fixing sleeve according to the invention which is introduced into a pre-wired tube by said first portion an optical cable is held in place inside of the axial hole which extends over the entire length of the sleeve, which of course appreciably limits the movements of the cable in the sleeve
  • said axial hole has an irregular wall, for example corrugated or grainy, which
  • said first portion has a low tronconicite
  • This arrangement has in addition the advantage of ensuring a better retention of the cable in the axial hole since the radial forces developed during the introduction of the sleeve into a tube tend to further enclose the cable in the hole This advantageous effect is made even more noticeable when said elastomer sleeve
  • the installation of an optical cable in the fixing sleeve, object of the invention is very simple and rapid since it suffices to open the continuous slot of the sleeve by opposing the elasticity of the material, d '' introduce the cable and let the slot close under the effect of the elastic return of the sleeve to its initial shape II therefore there is no need to cut the cable or thread it into the sleeve ction of the cable in the sleeve is further facilitated when, according to the invention, said first longitudinal tronconicite
  • the invention has other advantages such as the protection of the cables in the prewiring tubes and the sealing of these tubes which provides them with a good seal against foreign bodies (dust, etc.).
  • the following description with reference to the accompanying drawings, given by way of non-limiting examples, will make it clear what the invention consists of and how it can be implemented.
  • FIG. 1 is a perspective view of a fixing sleeve 5 according to the invention
  • Figure 2 is a longitudinal sectional view of the fixing sleeve of Figure 1
  • Figures 1 and 2 is shown in perspective and in section a sleeve 1 0 for fixing optical cables more specifically intended for I O internal wiring of buildings through pre-wired tubes
  • This sleeve 10 is made of elastic material, in particular elastomer and comprises two separate portions extending along the same axis A
  • a first portion 1 1 is substantially cylindrical, but advantageously slightly frustoconical so as to facilitate the introduction 15 of the sleeve 10 in a pre-wired tube 21, as illustrated more particularly in FIG. 2
  • This first portion 1 1 is also provided with a chamfer 1 1 1 at the end for a better introduction of the sleeve 10 into the tube 21
  • a second portion 12 is substantially conical with a more marked conicity than in the case of the first portion 1 1 The bending of 0 this second portion, and therefore the curvature of the cable 20 outside the tube 21 is a function of the conicity given to the second portion 12
  • An axial hole 1 3 is arranged all along the sleeve 1 0, substantially in its center, so as to receive an optical cable 20 This is why the diameter of the axial hole 1 3 can be taken in the order of the diameter of 5 optical cable 20
  • the sleeve 1 0 is continuously split over its entire length so as to communicate the outside of the sleeve with the axial hole 13, this in order to be able to introduce the cable 20 in the hole 13 More specifically, a first longitudinal slot 0 1 10 is formed in the first portion 11 of the sleeve, while a second slot 120 is produced in the form of a spiral in the second portion 12 of the sleeve
  • the optical cable 20 is maintained over the entire length of the axial hole 13 by hydrostatic tightening due to the transmission by the material of the sleeve 1 0 of the forces generated by the i introduction of the sleeve into the tube 21
  • the retention of the optical cable is increased by the fact that the internal wall 14 of the sleeve is irregular, namely annular or grainy for example
  • said first portion 1 1 of the sleeve 10 is introduced into the pre-wired tube 21 jus ⁇ u'à hold by clamping the sleeve in the tube The latter is then perfectly closed and sealed In this position, the cable 20 is insensitive to longitudinal movements that it could undergo in the tube 21
  • the spiral shape of the slot 120 in the conical portion 12 ensures a certain flexibility of the sleeve, this within limits of curvature compatible with the resistance of the cable 20 to bending
