Abstract
Abstract An improved optical connector for connection between two pairs of optical connectors is proposed. It consists of a female housing and a male housing. One of the housings is adapted to hold plugs carrying the optical fibers with some clearance left with respect to the inner wall to allow lateral displacement of the plugs for self-alignment between the optical fibers connected.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
142 words
A dual optical connector for connection between optical elements, comprising: a first housing adapted to rigidly hold plugs each carrying an optical element, a second housing coupled to said first housing and adapted to elastically hold plugs each carrying an optical element, said first housing being formed with a pair of tapered alignment holes having alignment surfaces into which said plugs are inserted and aligned, said plugs held in said second housing having outwardly projecting tapered alignment surfaces adapted to engage said first housing alignment surfaces, said second housing having a forward wall formed with openings that freely pass said plug tapered alignment surfaces with said tapered alignment surfaces extending entirely forward of said wall openings, said plugs being supported by said second housing and being displaceable in a lateral direction relative to said openings and urged by springs into alignment holes.
Claim 2
Dependent Claim
142 words
A dual optical connector for connection between optical elements, comprising: a first housing adapted to rigidly hold plugs each carrying an optical element, a second housing coupled to said first housing and adapted to elastically hold plugs each carrying an optical element, said first housing being formed with a pair of tapered alignment holes having alignment surfaces into which said plugs are inserted and aligned, said plugs held in said second housing having outwardly projecting tapered alignment surfaces adapted to engage said first housing alignment surfaces, said second housing having a forward wall formed with openings that freely pass said plug tapered alignment surfaces with said tapered alignment surfaces extending entirely forward of said wall openings, said plugs being supported by said second housing and being displaceable in a lateral direction relative to said openings and urged by springs into alignment holes.
Claim 3
Dependent Claim
34 words
A dual optical connector as set forth in claim 1 wherein the springs are resilient in the lateral direction for permitting the plugs held by the second housing to move in the lateral direction.
