US 5,349,916 A · System for effecting underwater coupling of optical fiber cables characterized by a novel pod-to-vehicle interlock

Abstract

A submarine trails one fiber optic cable and an undersea vehicle is contred by this first cable. A missile/torpedo trails a second cable that is to be coupled to the first cable. The second cable has a segment suspended vertically underwater between a buoyant pod and a sea anchor type buoy. The undersea vehicle, or Autonomous Undersea Vehicle, (AUV) hunts for the pod by a conventional homing transmitter, and a fork-shaped cable capture probe on the vehicle direct the cable's movement relative to the vehicle into a pod mating position in which a male plug portion in the underside of the pod mates with a female socket in a slot formed at the vertex of the fork. An interlock mechanism between the male socket and female socket holds the pod and AUV in engagement wherein optical coupling is achieved.

Dependent claims

An undersea vehicle and cable coupling system comprising:

a buoyant pod;
a cable suspended from said pod, a V-shaped cable engaging probe provided on said vehicle such that said cable can be engaged by the open end of said V-shaped probe as a result of moving said vehicle transversely toward said cable;
plug means including a male plug portion on said pod provided axially around said cable;
said plug means also including a socket part at the vertex of said V-shaped probe whereby continued transverse movement of said vehicle causes said cable to slide along said V-shaped probe until engaged by said pod male plug portion;
and
said plug portion including a lifting pin mechanism provided in said male plug portion for engaging said socket whereby said probe is secured to said pod and said cable coupled to said vehicle, said lifting pin mechanism having locking devices, and biasing means for urging said locking devices toward positions wherein they engage detents in said socket part.
