AI Technical Summary

Technical Problem

Traditional electrical connectors, which rely on nuts for locking, are not reliable and stable enough to meet the requirements. They are prone to loosening, leading to unstable telecommunication transmission and waterproofing failure, and are also inconvenient to install and disassemble.

Method used

The locking ring assembly includes an outer ring, an inner ring, and an elastic element. The outer and inner rings are slidably nested together. Through the cooperation of the limiting groove, the stop block, and the elastic element, quick locking and disassembly can be achieved to prevent loosening.

Benefits of technology

It achieves stability and reliability of electrical connections, prevents loosening, ensures stable and reliable connections, and allows for quick and convenient assembly and disassembly.

Abstract

The present invention relates to an electrical connector, comprising a locking ring assembly. The locking ring assembly has a first stop block and a second stop block having a variable spacing therebetween. When a male connector is mated with a female connector, an outer ring is slid, such that the first stop block and the second stop block move toward each other and a distance therebetween decreases. The locking ring assembly is then rotated, and the first stop block and the second stop block, after being brought into contact, move from an entry groove through a guide groove to enter a position-locking groove. After the first stop block and the second stop block enter the position-locking groove, the outer ring is released, such that the spacing between the first stop block and the second stop block increases, and a blocking portion blocks the first stop block and / or the second stop block to achieve locking. Similarly, during disassembly, reverse steps are performed. That is, the outer ring needs to be axially moved with a continuously applied force, while a male connector or a female connector provided with an engagement groove is held and then the locking ring assembly is rotated. Unlocking cannot be achieved by axial movement alone, rotational movement alone, contacting the locking ring assembly alone, or touching the male connector / female connector alone. Loosening does not occur in the axial direction due to restriction by the position-locking groove, thus providing a stable connection, high reliability, and enabling convenient and rapid assembly and disassembly.
