Optical fiber connector plug and unlocking clamp portion thereof

Abstract

The invention relates to an optical fiber connector plug and an unlocking clamp portion thereof. The front end of a plug housing of the plug is movably sleeved by an unlocking sleeve; the front end sleeve wall of the unlocking sleeve is provided with a radial through hole; the front end of the plug housing is provided with a locking barb which passes through the through hole from the inside out and is used for cooperating with an elastic clamp buckle of a corresponding socket housing; the front end of the locking barb is provided with a housing unlocking guiding face; the front side hole wall of the radial through hole is used for being in slide abutting cooperation with the housing unlocking guiding face when the unlocking sleeve moves back so as to press the locking barb to move inward along the radial direction; an unlocking arm is provided with a clamp unlocking guiding face; the unlocking sleeve is provided with an unlocking arm cooperation structure which is for being in slide abutting cooperation with the clamp unlocking guiding face when the unlocking sleeve moves back so as to press the unlocking arm to move to a locking arm. The invention provides the optical fiber connector plug which is high in connection and separation efficiency and the unlocking clamp portion thereof.

Description

technical field [0001] The invention relates to an optical fiber connector plug and an unlocking clip part thereof for optical signal transmission. Background technique [0002] In the field of optical communication, the DLC plug is a common LC connector. The DLC plug has been widely used around the world, but the DLC plug itself has poor protection effect and cannot be directly applied to harsh application environments such as outdoors. The existing The technology is to add a protective shell outside the DLC plug. Existing optical fiber connectors, such as the "optical cable connector for equipment access" disclosed in Chinese patent CN201262657Y, include a housing with a clip installed on the front end, and a tail cable locking structure connected to the rear end of the housing through a crimping screw sleeve. A bonding sleeve is pressed between the crimping screw sleeve and the optical cable. The bonding sleeve and the optical fiber protection layer of the optical cable ...

Problems solved by technology

When connecting (separating) plugs and sockets, multi-step operations are required, that is, connecting (separating) the shells of the plugs and sockets first, and then connecting (separating) the plugs and sockets; although the structure of the threaded connection is relatively simple, the connection and separation The efficiency is low, and when this kind of connector is tightened to the threaded docking socket, improper torque control can easily damage the connector, which is not convenient for construction and maintenance
