Description

  The present invention relates to an optical connector for connecting optical fiber cables.

  In recent years, it has been proposed to use optical communication via an optical fiber cable for exchanging signals with devices in a vehicle (see, for example, Patent Document 1). Optical communication is advantageous in terms of noise compared to electrical communication via a wire harness.

  For connection between optical fiber cables, for example, an optical connector as shown in FIG. 15 is used. The optical connector 5 shown in FIG. 15 includes a ferrule 510 as a connection terminal attached to the tip of an optical fiber cable 550 and a box-shaped housing 520 that accommodates the ferrule 510. The housing 520 is provided with a storage chamber 522 in which a cylindrical sleeve 521 into which the ferrule 510 is inserted is accommodated. An entrance hole is provided on the distal end wall of the housing chamber 522 opposite to the optical fiber cable 550 side in order to insert the mating ferrule provided on the optical connector to be connected into the sleeve 521. . The distal end of the mating ferrule inserted into the sleeve 521 from the entry hole and the distal end of the ferrule 510 positioned in the sleeve 521 are brought into contact with each other to establish a connection.

  Here, if the ferrule 510 moves to the optical fiber cable 550 side by the sleeve 521, a distance is increased between the ferrule 510 and the optical fiber cable 550, and the optical transmission loss increases. Therefore, in the optical connector 5 shown in FIG. 15, a spring member 530 that urges the ferrule 510 in the urging direction D51 opposite to the optical fiber cable 550 and pushes it into the sleeve 521 is provided. . The spring member 530 is held in the housing 520 in a state where the ferrule 510 is urged in the urging direction D51 by a spacer 540 attached to the housing 520.
