Abstract: The connector of the present invention is capable of insertion and removal of a plug having an unmoving section and a moving section that is movable with respect to the unmoving section. The connector includes a plug fixing member for fixing the unmoving section by movement of the moving section and the unmoving section in a plug insertion direction along with insertion of the plug into the connector, and for releasing the unmoving section by shifting of the moving section with respect to the unmoving section in a plug removal direction. On this account, it is possible to fix and release the plug according to the movement of the moving section of the plug.

Abstract: In an optical transmitter-receiver module for performing optical transmission and reception by using a single-core optical fiber, a light-tight partition plate unit 506 for separation between an optical path of a transmission signal light and an optical path of a reception signal light is held between a jack section 508 for detachably holding an optical plug 240 and a light emitting/receiving unit 505 which has an LED 514 and a PD 515 positioned and fixed in place and molded in one piece. The LED 514 is located at a larger a distance in a direction of optical axis from the optical fiber than the PD 515 is. The partition plate unit 506 is urged toward the optical fiber by springs.

Abstract: A mechanical lock type connecter of the present invention is for a plug including a non-movable member connected to a cable, and a movable member that makes relative movement in an axial direction of the cable independently from the non-movable member and the cable. The mechanical lock type connecter has arm sections for (a) holding the non-movable member in accordance with movement of the movable member in a plug inserting direction caused by inserting the plug and (b) releasing the plug by movement of the movable member in a plug detaching direction. By thus using the mechanical lock plug, provided is a mechanical lock type connecter that is capable of stably connecting the plug with the connecter and that makes it possible to downsize connecting portions of the plug and the connecter.
