Method of assembling an optical connector and an optical connector
View Patent ↗An optical connector and a method of assembling an optical connector that is capable of avoiding generation of unnecessary tension in the optical fiber cable in which plain fiber portions are optically connected to each other using a splice assembly. The optical connector comprises a connector housing having splice means configured to abut a stripped and cleaved end surface of a plain fiber of an optical fiber cable ( 2 ) onto an end of a fiber stub predisposed in the splice means to form an optical connection; and a cable fixing assembly ( 26, 40 ), that includes a cable fixing member ( 26 ) and a cable holder ( 40 ), for fixing an outer covering ( 2 c ) of the optical fiber cable ( 2 ) introduced into said connector housing ( 10 ). The cable fixing member ( 26 ), which includes an opposing piece ( 26 b ) for slidably engaging with a guide section ( 24 ) formed on the wall of an end cap ( 21 ) of the connector housing ( 10 ), is pressed in from the direction perpendicular to the axis of the optical fiber cable ( 2 ) and is mounted on the wall of the end cap ( 21 ). A step section is formed on the sliding surface of the opposing piece ( 26 b ) to be in sliding contact with the sliding surface of the guide section ( 24 ), for moving the cable fixing member ( 26 ) together with the optical fiber cable ( 2 ) so as to reduce a distance between the splice means ( 3 ) and the cable holder ( 40 ).
1. A method of assembling an optical connector, comprising the steps of:
inserting an optical fiber cable held in a cable holder from one end of a connector housing which has a splice means incorporated therein;
abutting an end surface of a plain fiber of said optical fiber cable with the covering removed therefrom onto an end surface of a counterpart plain fiber portion provided beforehand in the splice means so as to form an optical connection; and
fixing an outer covering of the fiber cable to said connector housing while moving said optical fiber cable toward said splice means so as to reduce a distance between the splice means and the cable holder, thus reducing tension on the plain fiber.
2. The method of claim 1 , wherein said fixing step comprises fixing an outer covering of the fiber cable to said connector housing while moving said optical fiber cable toward said splice means so as to reduce a distance between the splice means and the cable holder by a predetermined distance, thus reducing tension on the plain fiber.
