Abstract
The end (2) of an axial strength member is curved into a swan-neck (3) and gripped in a cold polymerized resin (4) which fills a cavity of a chamber (5) that is fixed relative to the junction box (6).
Claims1
A connection for connecting the ends of optical fiber cables within a junction box, said cables having a non-metallic axial strength member and a central core containing a plurality of optical fibers, said connection comprising:
- (a) an optical fiber connection cavity within said junction box for storing excess lengths of said optical fibers,
- (b) means for directing away the optical fibers from the ends of said central cores at the inlet of said connection cavity,
- (c) means for connecting together the ends of the optical fibers of the said cables within said optical fiber connection cavity,
- (d) said non-metallic axial strength members having swan-like curved ends, protruding into said optical fiber connection cavity, and
- (e) chambers forming gripping cavities filled with a cold polymerized resin, said chambers being fixed within said optical fiber connection cavity and receiving, respectively, said swan-like curved ends which ends are enclosed in said cold polymerized resin.
