In practical applications, the backplane is pre-installed in the cabinet, and the backplane The socket on the board usually needs to be pre-installed on the backplane, and the plug on the sub-board is installed as needed. Optical fiber transmission involves the connection of the optical fiber joints between the sub-board and the backplane. Due to the high quality requirements of the end faces of the optical fiber joints, it is usually necessary to consider dust-proof design when using it. For example, the Chinese patent with the publication number CN105242356A and the publication date is 2016.01.13 The application discloses a connector assembly, the connector assembly includes a plug and a socket, the front end of the socket housing is provided with a dust cover, the socket housing is also provided with an elastic driving mechanism that provides elastic force for the dust cover, the elastic driving mechanism Including the direct push spring and the force transmission part extending in the front and rear directions, the direct push spring and the force transmission part provide the flipping elastic force for the dust cover to prevent dust and other pollutants from entering the socket or plug. Turbulence will be generated, and the relative movement between the plug housing and the socket housing during the mating process of the plug and socket will also generate disturbance around the periphery of the plug-in end, and the surrounding dust will easily enter the socket and plug under the action of the disturbance. This causes the problem that the protection effect of the current connector is poor.
