Abstract
A connector for connecting together in a water-tight housing various optical instruments of an underwater or submarine arrangement having optical fiber cables. The connector is constructed in a manner such that a plug containing the terminals of optical fiber cables is connected in an easily attachable/detachable fashion to a receptacle which is mounted on the water-tight housing. Sealing material is interposed between the water-tight housing and the receptacle and between the receptacle and the plug for preventing the infiltration of water or sea water into the water-tight housing.
Claims6
A water-tight optical fiber connector comprising:
- a receptacle inserted in a water-tight container to be fixed integrally therewith;
- an annular, first sealing member for sealing said water-tight container and interposed between said receptacle and said water-tight container;
- an internal plug fixedly engaged with said receptacle in a manner to allow free attachment/detachment from inside said water-tight container and connected to ends of optical fiber cables in the water-tight container so as to have the center line of the optical fibers penetrate at the center thereof;
- an outer plug engaged with said receptacle in a manner to allow free attachment/detachment from outside said water-tight container to oppose said internal plug and connected to ends of optical fiber cables outside said water-tight container so as to have the center line of the optical fibers penetrate at the center thereof;
- pressing means screwed from outside said water-tight container into said receptacle for pushing said outer plug into said receptacle for fixation so as to make the opposing end surfaces of said internal plug and said outer plug abut each other;
- and a second sealing member interposed between said receptacle and said outer plug and communicating with the inside of said water-tight container for sealing the gap therebetween.
