Description

Technical Field

[0001] The utility model relates to the technical field of communication equipment, in particular to an optical fiber pigtail. Background Art

[0002] When connecting optical fibers, an adapter is needed to connect the tail ends of the optical fibers through the open sleeve inside the optical fibers to ensure the highest connection performance between the optical fiber jumpers. The optical fiber adapter is an important connecting component in the optical fiber active connector.

[0003] For example, Chinese patent CN 214669730 U discloses an LC fiber pigtail adapter. The present invention discloses an LC fiber pigtail adapter, which relates to the field of communication equipment. To address the problems of existing fiber pigtail adapters, such as poor protection, susceptibility to external environmental influences, short service life, and poor stability and performance, the present invention proposes the following solution: the adapter comprises a protective housing, the inside of which is mounted a pigtail adapter body, a docking tube mounted at both the input and output ends of the pigtail adapter body, a docking sleeve mounted on the sidewalls of the docking sleeve, a socket mounted on the side of the socket away from the docking sleeve, a connecting wire mounted on the side of the connecting wire away from the socket, and a push-pull plate mounted on the side of the baffle away from the connecting wire. The present invention has a novel structure, good protection, low connection difficulty, and high connection stability, thereby extending the service life of the optical fiber and adapter.

[0004] The background technology of the above-mentioned patent points out that when the existing fiber pigtail and adapter are used, they are easily affected by collision, which can affect the connection effect of the fiber pigtail and the adapter. Although the above-mentioned patent can use springs and other devices to improve the plug-in stability of the fiber pigtail, the spring has a certain elasticity. If the adapter and the fiber pigtail are subjected to shock force, the spring will rebound, causing the baffle to detach from the surface of the fiber pigtail, which may cause the fiber pigtail to detach from the inside of the adapter, thereby affecting the normal use of the fiber pigtail by people.
