Switching device and switching method for fiber optic micro cable of underwater robot

Abstract

The invention belongs to the field of fiber optic micro cables of underwater robots, and particularly relates to a switching device and a switching method for a fiber optic micro cable of an underwater robot. The switching device comprises cone dies and a main cavity die, wherein the cone dies are arranged at two ends of the main cavity die respectively; a main fiber optic micro cable is switched with another section of fiber optic micro cable through a fiber optic switching terminal; the main fiber optic micro cable and a tail optical fiber which are fused are accommodated in the main cavity die and the cone die; and sealants are respectively filled between the main fiber optic micro cable and the tail optical fiber as well as between the main cavity die and the cone dies. The switching method comprises the following steps: carrying out fusion treatment on the main fiber optic micro cable led from an airtight cabin or fiber optic receiving / transmitting device and the tail optical fiber containing the fiber optic switching terminal by a fiber optic melting machine so as to realize the fusion of fiber cores of two sections of optical fibers; under the assistance of the die, filling the sealants between the main fiber optic micro cable and the tail optical fiber; fusing the fiber cores as well as wrapping and sealing the edges of the fiber optic micro cable and the tail optical fiber; and standing the sealed article in air for half an hour and fusing to form a whole. The switching device and the switching method disclosed by the invention have the advantages of flexibility in splitting, reliability in sealing, simpleness in operation and the like.

Description
