Relay optical connector

摘要

In a relay optical connector 1, a part 16 of a ferrule 4 is butted against a part 17 of a ferrule 5 in a ferrule end face 14 of the ferrule 4 in which an optical fiber 2 for an optical connection is exposed and a ferrule end face 15 of the ferrule 5 in which an optical fiber 3 is exposed and the one optical fiber 2 and the other optical fiber 3 are arranged so as not to come into contact with each other. Specifically, one of the ferrule end faces 14 and 15 is surface-ground so as to extend along a surface at right angles to an optical axis L and the other thereof is diagonally surface-ground so as to be inclined at a prescribed angle θ relative to the surface at right angles to the optical axis.

1. A relay optical connector, comprising:
one optical propagation member for an optical connection; other optical propagation member; a first ferrule member having a first end face on which the one optical propagation member is exposed; and a second ferrule member having a second end face on which the other optical propagation member is exposed; wherein a part of the first ferrule member in the first end face of the first ferrule member is butted against a part of the second ferule member in the second end face of the second ferrule member and the one optical propagation member and the other optical propagation member are arranged so as not to come into contact with each other; and wherein one of the first end face and the second end face is surface-ground so as to extend along a surface at right angles to an optical axis and the other thereof is diagonally surface-ground so as to be inclined at a prescribed angle relative to the surface at right angles to the optical axis, wherein the first ferule member is a tubular ferule in which the one optical propagation member is inserted, wherein the second ferule member is a tubular ferule in which the other optical propagation member is inserted, wherein one of the first ferrule member and the second ferrule member is mechanically biased toward the other, wherein the relay optical connector includes a holder holding the other of the first ferrule member and the second ferrule member to regulate a position of the other ferrule member, and a sleeve into which at least a part of the first ferrule member and the second ferrule member are inserted such that a part of the first ferrule member and a part of the second ferrule member are abutted against each other, and each of the first ferrule member and second ferrule member include a front part inserted into the sleeve, an intermediate part whose diameter is larger than that of the front part and a rear part whose diameter is smaller than that of the intermediate part and the other of the first ferrule member and the second ferrule member is held in a position of the rear part by the holder.
