AVIC Optoelectronics applies for patents related to anti-fall retaining rings, which prevent parts from falling out through protrusions that work together to secure the components.

March 29 news: Information from the National Intellectual Property Administration shows that AVIC Optoelectronics Technology Co., Ltd. has applied for a patent titled “A retaining ring with anti-pulling-off function and a connector using the retaining ring.”

The publication number is CN121748877A, the application number is CN202610073250.0, the publication date is March 27, 2026, the application date is January 20, 2026, the inventors are Zhou Chaoxu, Zhou Bihai, Wang Guanmin, and Li Youlong, the patent代理机构 is Luoyang Huah e Intellectual Property Agency Co., Ltd. (General Partnership), and the patent代理师 is Yang Zhifeng. Classification numbers are H01R13/639, H01R13/502, and H01R13/40.

The patent abstract indicates that this invention relates to a connector structure, specifically a retaining ring with an anti-pulling-off function and a connector using the retaining ring. The retaining ring includes a retaining ring body with an opening. The retaining ring body includes an insertion portion for embedding into a retaining ring groove and a protruding portion for bearing axial force. On the non-force-bearing surface of the protruding portion, a raised feature is provided. During retaining ring assembly, the raised feature is used to come into contact with the load-bearing inner wall of the retaining ring installation structure, and there is a gap between the insertion portion and the bottom wall of the retaining ring groove. By providing a raised feature on the non-force-bearing surface of the retaining ring, the force-bearing surface blocks the corresponding component. The outer wall of the raised feature abuts against the load-bearing inner wall of the connecting lock nut. The insertion portion leaves a gap with the bottom wall of the retaining ring groove. When the component blocked by the retaining ring is subjected to a force tending to pull outward, through the cooperation between the raised feature and the inner wall of the retaining ring installation structure, the retaining ring is subjected to a pair of balanced forces, preventing the retaining ring from disengaging and thereby preventing the component within the retaining ring installation structure from escaping.
