AVIC Optoelectronics obtains patents related to connector sealing components, with the connector tail seal assembly achieving multiple reliable seals.

On March 28, news reported that the National Intellectual Property Administration’s information indicated that AVIC Optoelectronics Technology Co., Ltd. has applied for a patent titled “A Sealing Assembly for the Rear End of a Connector,” with authorization announcement number CN224035668U, and the authorization announcement date is March 24, 2026. The application number is CN202520637497.1, the application publication date is March 24, 2026, the application date is April 7, 2025, and the inventors are Liu Yajun, Xue Jingang, Sun Mingjie, Gao Jian, and Li Weike. The patent agency is Luoyang Gongxin Intellectual Property Office (General Partnership), and the patent agent is Chang Xiaohu, with the classification number G02B6/38.

The patent abstract indicates a sealing assembly for the rear end of a connector, which includes a sealing plug and a connection assembly. The front end of the sealing plug is sealed and connected to the rear end of the connector housing, and the rear end of the sealing plug is designed to abut against the connection assembly, with a cable passing hole provided on the sealing plug for the connector’s cable to pass through, tightly wrapped around the cable’s exterior. The connection assembly includes a rear connection piece and a compression ring arranged within the rear connection piece. The front end of the rear connection piece is fixedly connected to the connector housing, and one end of the compression ring facing the sealing plug is designed to press against the sealing plug’s sealing surface. This utility model can prevent the situation where the snap parts easily undergo plastic deformation after repeated compression, leading to the rubber ring being unable to assemble correctly, achieving a reliable sealing effect even after multiple assemblies.
