US 5,708,746 A · Rail-type device for mechanically splicing optical fibers

Abstract

A structurally improved rail-type device for mechanically splicing optical fibers while reducing the splicing loss is disclosed. The above splicing device not only has a cladding clamp with a seesaw structure thereby easily splicing the optical fibers, it also separately moves the covers relative to the body to easily perform the tuning operation. Due to coating clamp's protrusions and body's slots engaging with each other, the coating clamp exclusively vertically move relative to the body and prevent the optical fibers from being axially thrust. The splicing device further seperately clamps the coating and cladding parts of the optical fibers, thereby preventing the spliced fibers from breaking due to tensile or torsional force. The sliding motion of the covers relative to the body is achieved by the rails of the covers and rail grooves of the body.

Dependent claims

A rail-type device for mechanically splicing optical fibers of a single or multi-core structure, comprising:

a body opened upward to form a splicing space therein, both bottom side edges of said body being provided with axially extending rail grooves;
a base panel received in said splicing space of the body and having a V-shaped groove, said base panel having a top surface, said V-shaped groove being axially formed on the top surface of said base panel and adapted for laying the optical fibers therein;
a cladding clamp and a coating clamp placed on said base panel to move up and down, thereby selectively clamping the cladding and coating parts of the optical fibers respectively;
and
a cover slidably engaging with said rail grooves of said body and adapted for selectively pressing said cladding and coating clamps down to fix the optical fibers in said base panel.
