Abstract
An optical connector includes: optical fibers including bare portions and covering portions covering the bare portions; a ferrule that accommodates parts of the optical fibers where the bare portions are exposed; a stress relaxation portion that accommodates parts of the optical fibers where the covering portions are formed and relieves a stress acting on the optical fibers; and a boot that has an insertion hole through which the optical fibers are inserted and that connects the ferrule and the stress relaxation portion. The ferrule, the boot, and the stress relaxation portion are separately formed and fixed to each other. The stress relaxation portion includes a constricted portion therein.
Claims6
An optical connector comprising:
- optical fibers comprising bare portions and covering portions covering the bare portions;
- a ferrule that accommodates parts of the optical fibers where the bare portions are exposed;
- a stress relaxation portion that accommodates parts of the optical fibers where the covering portions are formed and relieves a stress acting on the optical fibers;
- and
- a boot that has an insertion hole through which the optical fibers are inserted and that connects the ferrule and the stress relaxation portion, wherein
- the ferrule, the boot, and the stress relaxation portion are separately formed and fixed to each other,
- the stress relaxation portion comprises a constricted portion therein, and
- a width of the constricted portion in a lateral direction of the optical fibers decreases from the front side toward the rear side in a configuration where the ferrule accommodates the optical fibers side by side in the lateral direction, the ferrule is positioned at a front side in a longitudinal direction and the stress relaxation portion is positioned at a rear side in the longitudinal direction.
A method for manufacturing an optical connector, the method comprising:
- adhesively fixing parts of optical fibers, where bare portions are exposed, to an inside of a ferrule;
- adhesively fixing a boot to the ferrule, such that the optical fibers are inserted into an insertion hole of the boot;
- and
- fixing a stress relaxation portion to the boot such that the optical fibers are inserted into the stress relaxation portion.
