Definitions

  • the invention relates to a cable sleeve for the structured storage or handling of optical waveguides guided in optical waveguide cables according to the preamble of claim 1.
  • Cable sleeves for structured storage or handling of fiber optic cables routed in optical waveguide cables are used in optical fiber cable networks for the protection of splices at connection points of two optical fiber cables and for protecting the optical fibers at branch points or at splitting points of optical fiber cables.
  • the cable sleeves must ensure the continuity of the fiber optic cable as if the fiber optic cables were not interrupted.
  • the structured storage and gentle handling of the optical waveguides plays a decisive role in this, so that the transmission properties of the optical waveguides are not adversely affected.
  • a cable sleeve with the features of the preamble of claim 1 is known from EP 0 646 294 B1.
  • the cable sleeve disclosed therein comprises a covering body as well as a sealing body insertable into an opening of the covering body, wherein the sealing body comprises a gel-like sealing material which is arranged between two dimensionally stable plates.
  • the sealing body is displaceable in a cavity in the axial direction inwards and outwards with respect to the covering body, in order to compensate for pressure differences between an internal pressure and external pressure of the cable sleeve. Depending on this pressure difference, the seal body comes into contact with different stops.
  • FIGS. 1 to 7 the invention will be described in detail below with reference to a cable sleeve designed as a hood sleeve for the structured deposition or handling of optical waveguides guided in optical waveguide cables.
  • Fig. 1 to 6 relate to a first embodiment of the invention Phyg
  • Fig. 7 shows a second embodiment of the cable sleeve according to the invention.
  • the cover 11 and the interior 12 thereof are in the context of the present invention spring elements 23 integrated.
  • the spring elements 23 are accommodated in projections 24 formed on an inner side or inner surface of the covering body 11.
  • the projections 24 protrude radially inwards relative to the inner surface of the cover body 11 and thus protrude into the inner space 12.
  • a dimensionally stable end of the seal body 14 namely the inner end piece 17, abuts against the spring elements 23 and on the projections 24.
  • the projections 24 form stops for the sealing body 14 and limit the insertion depth thereof into the covering body 11.
  • the spring elements 23 store the force applied to close the cable sleeve 10 and permanently hold the gel element 18 of the sealing body 14 under compression pressure.
  • the seal body 14 is sealed relative to the cover body 11 of the cable sleeve 10 of the invention.
  • the installation position of the sealing body 14 in the cover body 11 is defined as shown in FIG. 2 by the sealing body 14 associated projections 25 which are inserted into slot-like recesses 26 of the cover body 11.
  • each half 19 and 20 of the sealing body 14 associated with such a projection 25, wherein each of the two projections 25 in each case a slot-like recess 26 of the cover 11 is insertable.
  • the projections 25 are associated with the dimensionally stable end piece 16 of the sealing body 14 which is located on the outside in the assembled position of the cable sleeve 10.
  • the cable sleeve 10 has a closure body 27 designed as a closure cap, which closes the cable sleeve 10 and fixes the sealing body 14 on the covering body 11.
  • the closure body 27 designed as a closure cap can be fastened to the cover body 11 via a bayonet-type closure mechanism 28, wherein the bayonet-type closure mechanism 28 is formed by protrusions 29 formed on an outer surface of the cover body 11 and slot-like recesses 30 in the region of the closure body 27.
  • the projections 29 of the cover body 11 are inserted into the recesses 30 of the closure body 27, in which case the closure body 27 relative to the cover body 11 is rotatable. After the closure body 27 has been rotated relative to the cover body 11, the projections 29 according to FIG. 1 engage in corresponding undercuts of the recesses 30.
  • the sealing body 14 is then, when the same in the uncompressed state with the inner end piece 17 rests against the projections 24, at least in sections with the outer end piece 16 against the cover body 11 before or protrudes at least partially out of the same.
  • the closure body 27 is screwed to the cover body 11 in the manner of a bayonet, the gel element 18 of the sealing body 14 being compressed due to the fact that the sealing body 14 bears against the projections 24 with the inner end piece 17.
  • the recorded in the projections 24 spring elements 23 are compressed, which store the force applied to close the cable sleeve 10 force and hold the gel element 18 of the seal body 14 permanently under compression pressure. In this way, a temperature-induced change in the behavior of the gel element 18 can be compensated or compensated and a good sealing effect of the same can be ensured.
  • the closing body 27 designed as a closure cap is designed to be open on its end face in such a way that the openings 15 of the sealing body 14 are not covered.
  • the in the assembled state of the cable sleeve 10 outside, dimensionally stable end 16 of the seal body 14 comes to a peripheral edge 31 of the closure body 27 to the plant.
  • FIG. 7 shows a second embodiment of a cable sleeve 35 according to the invention, which differs from the embodiment of FIGS. 1 to 6 only by the configuration of the closure body. To avoid unnecessary repetitions, therefore, the same reference numerals are used for the same components and reference is made to the embodiments of, for example, FIGS. 1 to 6. In the following, only the details will be discussed, by which the embodiment of FIG. 7 differs from the embodiment of FIGS. 1 to 6.
  • FIG. 7 differs from the embodiment of FIGS. 1 to 6 only by the design of the closure body, wherein in the embodiment of FIG. 7, two closure bodies 36 designed as closure stirrups are present.
  • hooks 37 of the closure bow 36 can be inserted into recesses 38 of the sealing body 14, wherein in the closure position shown in FIG. 7 the closure bar 36 presses the sealing body 14 against the spring elements 23 and projections 24 integrated in the covering body 11.

Abstract

L'invention concerne un manchon de câble pour la dépose ou la manipulation structurée de fibres optiques, comprenant un corps (11) de protection définissant un espace (12) intérieur, notamment un capot de protection, et un corps (14) d'étanchéité pouvant être introduit dans une ouverture (13) du corps (11) de protection, servant à l'introduction de câbles à fibres optiques dans l'espace (12) intérieur et/ou à la sortie de câbles à fibres optiques hors de l'espace (12) intérieur et comprenant deux embouts (16, 17) indéformables et un élément (18) en gel comprimable disposé entre les embouts. Conformément à l'invention, des éléments (23) ressorts sont intégrés dans l'espace (12) intérieur du corps (11) de protection, reposent contre l'un des embouts (17) indéformables du corps (14) d'étanchéité lorsque le corps (14) d'étanchéité est introduit dans l'ouverture (13) du corps (11) de protection et comprimé et exercent sur l'élément (18) en gel une pression de compression permanente.
