Optical connector and optical fiber connecting system
View Patent ↗A straight type optical connector enables a splicing operation of an optical fiber cable accurately and stably without requiring skilled labor and having a superior on-site installation property. An optical connector is provided with a splicing section for securely supporting an incorporated optical fiber securely supported at a ferrule and an optical fiber of an outside optical fiber cable in an end-abutting condition. The body of the optical connector is provided with a cable holding member able to hold an optical fiber cable. The cable holding member can be set at a temporary position where it makes an optical fiber of the optical fiber cable abut against the incorporated optical fiber at the splicing section in the state holding the optical fiber cable and bends a covered optical fiber of the optical fiber cable between the splicing section and the cable holding member by a pressing force in the lengthwise direction.
1. An optical connector, comprising a body; a ferrule provided in said body; an incorporated optical fiber with a predetermined length, securely supported on said ferrule; and a splicing section provided in said body near said ferrule and able to operate so as to securely support said incorporated optical fiber projecting out from said ferrule and an optical fiber of an optical fiber cable introduced from outside of said body in an end-abutting condition, characterized in that:
said optical connector further comprises a cable holding member provided in said body at a location opposite to said ferrule with said splicing section disposed therebetween, said cable holding member being able to hold an optical fiber cable; and in that
said cable holding member is movable with respect to said body in a direction substantially parallel to an extending direction of said incorporated optical fiber; said cable holding member being able to be set, in the state holding the optical fiber cable, at a temporary position where said cable holding member makes the optical fiber of the optical fiber cable abut against said incorporated optical fiber in said splicing section and bends a covered optical fiber of the optical fiber cable between said splicing section and said cable holding member by a lengthwise pressing force, wherein said cable holding member is able to be set at a finished position where, after said splicing section securely supports said incorporated optical fiber and said optical fiber of said optical fiber cable in said end-abutting condition, said lengthwise pressing force applied to said covered optical fiber of said optical fiber cable is substantially released.
2. An optical connector as set forth in claim 1 , further comprising an anchoring structure for temporarily anchoring said cable holding member at said temporary position on said body.
3. An optical connector as set forth in claim 1 , further comprising an anchoring structure for anchoring said cable holding member at said finished position on said body.
4. An optical connector as set forth in claim 1 , wherein said body includes an indicator showing a fact that said cable holding member is located at said temporary position in a manner visually confirmable from outside of said body.
5. An optical connector as set forth in claim 1 , wherein said cable holding member is provided with a receptive groove for receiving the optical fiber cable and an engaging projection for engaging with a sheath of said optical fiber cable in said receptive groove and statically holding said optical fiber cable in said receptive groove.
6. An optical fiber connecting system, comprising a first optical connector as set forth in claim 1 and a second optical connector having a second ferrule to be concentrically abutted against said ferrule of said first optical connector; said first and second optical connectors being detachably combined with each other.
