Abstract
Abstract A pair of frusto-conical optical connectors which allow for the grouping of 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 frusto-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 frusto-conical configuration prevents the movement of terminals within the channel toward the low pressure area. The terminal configurations provide for precise juxtaposition of lenses used in the optical connections.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
195 words
A pair of mating connectors for transferring optical signals from at least one fiber-optic cable to another optical device which comprises: each of said connectors having a mating interface shaped and dimensioned to intimately contact the mating interface of the other connector; means, for transferring said optical signals, comprising at least one optical terminal in optical alignment with said cable and with said other optical device when said mating interfaces are brought together; and at least one channel in each of said connectors opening into said interface, each of said channels having a frusto-oconical area tapering towards said mating interface, wherein each of said terminals occupies one of said channels each said terminals has a corresponding frustroconical sections dimensioned to intimately rest within said frustroconical area and to prevent any axial movement of said terminal toward said interfaces; wherein each of said channels has an hexagonal, radial cross-section; and wherein each of said terminal comprises a spherical lens in two half sections; said sections being housed in two opposite channels of said connectors so that the two half sections abut each other in a complete spherical lens configuration when said mating interfaces are brought together.
Claim 2
Dependent Claim
