Protection cap for optical connector

摘要

The protection cap is removably attached to an optical connector or a hybrid connector each having a cable ferrule therein. The cable ferrule has an end face at which an optical core cable is exposed. The protection cap has a locked portion engaged with a lock portion of the optical connector or the hybrid connector and has a projection (23) on an innerwall of the protection cap for protectively covering the end face of the cable ferrule. The protection cap is defined in a box shape, which can be molded by one or more molding dies that can be removed parallel to an engagement direction of the protection cap with the connector.
