Wet-mateable electro-optical connector

Abstract

An electro-optical connector has a plug unit and a receptacle unit which are releasably mateable in an underwater environment. Each unit has at least two separate contact chambers extending inwardly from the front end, one for containing optical contacts and the other for containing electrical contacts. Each optical contact chamber is sealed by a rolling seal member rotatably mounted in a recessed seat in a front end wall of the chamber for rotation in a non-axial direction between a closed position in which a seal through bore is offset from an inlet into the chamber and an open position in which the seal through bore is aligned with the inlet. One electrical chamber contains an electrical socket and has a front end wall having a sealable opening, an annular seal member mounted in the sealable opening, and a resiliently biased stopper movably disposed in sealing engagement within the annular seal member when the units are not mated. The other electrical chamber contains a conductive probe adapted for insertion through the sealable opening in the first electrical contact chamber to sealably engage the annular seal member and move into electrical contact with the socket. Thus, the electrical sealing arrangement is completely separate and different from the optical sealing arrangement.
