A splice for crimping optical fibers includes two half-cylinders, a support block and a pressing block, which are mutually pressed by a crimping cylinder. The support block is provided with a longitudinal groove for receiving the stripped fiber and bears capped edges. The capped edges and stops are symmetrically mounted on either side of the longitudinal axis of the half-cylinders and are designed for maintaining axis of the half-cylinders and are designed for maintaining a small space between the two half-cylinders in the zone where they are located.

Mechanical splice for crimping optical fibre

The invention relates to a sealing device constituted by a round seal (,), that is to say a seal having a non-planar outer surface, and by a flat seal (,) which are contiguous, characterised in that, on either side of the round seal (,) and in the area of the flat seal (,), projects a planar lug (,) moulded in a single piece with the seal body (,), each of the said two lugs (,) fitting into a cut out portion of a matching shape provided in the flat seal (,), so as to locate the interface between the round seal (,) and the flat seal (,) entirely in the plane of the latter.

Cross-over between a round seal and a flat seal

The tool is constituted, on one hand, by a lower plate (12) traversed by a calibrated orifice, between an admission chamber (14) equipped with a roller (18) and a cutting plate (15) and, on the other hand, by an upper cover (22) also pierced by an opening (24) emerging in an inlet chamber (26) equipped with a roller (28). The upper cover is placed above the lower plate at distance that is variable so that the calibrated orifice and the opening are aligned, or can be offset heightwise.

The device comprises a central spicing body serving to connect in situ two cable end plugs which fit into the splicing body. The central body has lower rails hollowed out therein and bears lateral shoulders for guiding and locking the end plugs constituted by a lower part and by an upper part fixed to one another by a press fit. The device has application in the in situ splicing of optical fibers.
