Abstract:
An optical connector device comprising:a first optical connector for holding an end portion of an optical fiber cord; and a second optical connector for holding other optical fiber cord or an optical element which is to be optically coupled to said optical fiber cord; wherein when said first and second optical connectors are connected together, said optical fiber cord and the other optical fiber cord or said optical element, held respectively by said two optical connectors, are optically coupled together; said first optical connector comprises: a housing portion of a generally tubular shape, a stopper; a cord receiving hole portion, in which said optical fiber cord can be inserted and received in an axial direction of said housing portion, and is formed in said housing portion, and a mounting opening portion, through which said cord receiving hole portion communicates with the exterior, is formed in one side portion of said housing portion, and said stopper is inserted into said cord receiving hole portion through said mounting opening portion in a direction perpendicular to the direction of insertion of said optical fiber cord, and is engaged with a covering portion of said optical fiber cord in said cord receiving hole portion to hold said optical fiber cord in a manner to position the same in the axial direction thereof; said second optical connector includes: a holding portion for holding said other optical fiber cord or said optical element, and a tubular fitting portion which extends beyond a distal end of said holding portion, and can fit on said housing portion of said first optical connector; and said tubular fitting portion is formed into such a shape that in a mutually-connected condition of said first and second optical connectors, the whole or part of a peripheral wall of said tubular fitting portion extends to reach said mounting opening portion to cover at least part of said mounting opening portion.
