US Patent:
5838857, Nov 17, 1998
Filed:
Apr 7, 1997
Appl. No.:
8/826705
Inventors:
Edward J. Niekrasz - Bonita CA
Assignee:
Lockheed Martin Corporation - Bethesda MD
International Classification:
G02B 638
US Classification:
385 56
Abstract:
A connector plug half includes a telescopic cover sleeve which can be pushed by a connector receptacle half during mating to a receded position to thereby deploy radially outward one or more flexible tubes, each having at the ends thereof an optical contact. The telescoping movement opens a dielectric chamber in which the optical contacts are maintained. The connector receptacle half includes one or more optical receptacle contacts in a peripheral dielectric chamber. An internal cover sleeve is telescoped to a receded position in the connector receptacle during mating to thereby join the two dielectric chambers when the optical connection is made. The dielectric chambers remain free of contamination by fluid external to the connector halves.
