Abstract

The present invention provides an optical connector in which the sheath is not easily displaced in the rotational direction with respect to the housing even when a moment is applied to the sheath. The optical connector according to the present disclosure includes: a ferrule; a housing that accommodates a floating mechanism that enables the ferrule to retract so as to press the ferrule; a coupler attached to the outer side of the housing; and a sheath attached to the floating mechanism the rear side of the spring bush. The spring bush has: a cylindrical part; a flange part formed on the outer periphery of the cylindrical part; a groove part formed on the front side of the flange part; and a convex part protruding outward from a part of the outer peripheral surface of the groove part. The sheath has: a claw part formed on the front edge of the front opening of the sheath and hooked to the groove part; and a concave part formed on the front edge of the front opening of the sheath, and the convex part is engaged.

Description

technical field [0001] The present invention relates to optical connectors. Background technique [0002] As an example of an optical connector, for example, an MPO connector (an F13-type multi-core optical fiber connector defined in accordance with JIS C5982) is known. The optical connector includes a ferrule, a shell, and a sheath. The housing accommodates a floating mechanism for pressing the ferrule so that the ferrule can retreat together with the ferrule. In addition, a coupler is attached to the outer side of the case. The coupler is a member that releases the lock of the optical connector. The lock of the optical connector is released by pulling the coupler to the rear side (when unplugging the optical connector, pull the coupler to the rear side). The sheath is arranged on the rear side of the casing. [0003] Patent Document 1 describes such an optical connector (MPO optical connector). [0004] Patent Document 1: Japanese Patent Laid-Open No. 2013-246321 ...
