Abstract
An optical connector 10 includes slide pins 16a and 16b, held for movement in a direction of an axis of the optical connector 10, and a proximity switch 21 whose conducting state can be switched in response to the movement of the slide pins. Only when the optical connector 10 is properly connected to an optical receptacle 11, the proximity switch 21 is turned into the conducting state.
Claims26
A connector with a connection detection function, said connector being adapted to be connected to a fixed receptacle and comprising:
- a body in which a longitudinally extending member is centrally mounted, said body including an attachment member to be secured to said fixed receptacle, and a retaining member fixedly mounted to said longitudinally extending member and holding said attachment member;
- a moving member movable in an axial direction of said connector relative to said body, said moving member including at least one slide pin disposed in a gap between said longitudinally extending member and said retaining member, and a sensing member fixedly secured to a proximal end of said slide pin;
- and
- a switch that can be changed between an electrical conducting state and an electrical non-conducting state in response to contact with said sensing member due to movement of said moving member when said connector is properly fitted onto said fixed receptacle, to thereby detect a proper connection between said connector and said fixed receptacle.

An optical fiber cable with a connection detection function comprising:
- a pair of connectors mounted on opposite ends of an optical fiber and adapted to be connected to respective fixed receptacles, each of said connectors including,
- a body on which the optical fiber is mounted,
- a moving member movable in an axial direction of said connector relative to said body, and
- a switch that can be changed between an electrical conducting state and an electrical non-conducting state in response to the movement of said moving member when said connector is properly fitted onto said fixed receptacle;
- and
- a loop-shaped electric wiring extended along said optical fiber and linked through said switch to each of said connectors, wherein said loop-shaped electric wiring is normally maintained in a non-conducting state, further said loop-shaped electric wiring is changed from the non-conducting state to a conducting state when both of said connectors are properly connected to said respective fixed receptacles.
