Abstract
Abstract A pair of hybrid electro-optical connectors which allow for the grouping of a mixture of electrical and optical connections in a versatile housing where clusters of terminal-holding channels are arranged in a beehive configuration. Automatic alignment of the terminals is achieved by means of magnets of opposite polarity occupying some of these channels. The connectors are particularly adapted to underwater applications or to any other severe environment and hard-to-reach locations where manipulation is limited due to the use of diving suits or robotics. The frustro-conical configuration of sections of the channels and the terminals provides for the use of the connectors as part of bulkheads between two areas with very high differential pressure. The frustro-conical configuration prevents the movement of terminals within the channel toward the low pressure area. The terminal configurations provide for wiping action of mating electrical terminals and precise juxtaposition of lenses used in the optical connections.
