Title: Holder with kinking protection for a fibre splice
Inventor: ECKARDT FRITZ DIPL ING
IPC: G02B6/38
Filed: 1994-02-25
Abstract: If in electrical telecommunication two optical waveguide cables are to be spliced together, their ends are inserted into a cable fitting and the optical waveguides, designed as optical fibres, are spliced to each other. The fibre splices thus obtained are provided with splice protection. In the case of optical fibre cables of tightly buffered fibres with firmly adhering secondary protection (secondary coating), the secondary protection can be removed only so far that it ends, after the fitting of the splice protection, a few millimetres in front of it. This has the disadvantage that the short piece of the optical fibre which is protected only by the primary coating is subject to an increased risk of breaking between the end of the secondary protection and the splice protection. This risk of breaking is overcome by the invention as follows: the fibre splice is surrounded with splice protection (SpS). The fibre splice thus obtained is then inserted into a holder (A) which can be produced as a plastic injection-moulded part and thus in a cost-effective manner. The holder is designed in such a manner that the fibre splice can be inserted therein without any tools. The holder (A) has position-securing elements (LE1, LE2) into which the secondary protection of the fibre is snapped and held by spring forces. <IMAGE>
