Technical Field

[0001] This utility model relates to the field of connector technology, specifically a crimp-type plug structure. Background Technology

[0002] Circular connectors are a type of connector with a basic cylindrical structure and a circular mating surface. They are mainly used for the mating connection of wires and data cables, and have advantages such as a stable structure. Circular connectors generally include two structures that are mutually plugged and mated: a plug and a socket.

[0003] In traditional circular connector plugs, the socket is located inside the socket insulator and is locked in place by a socket cover. The socket cover is installed and fixed by bolts passing through the socket insulator and nuts. In this structure, the nuts are small and light, making them difficult to handle and prone to falling off or being lost during installation or disassembly. At the same time, the bolt and nut connection structure may loosen and fall off due to external factors over time.

[0004] Therefore, the inventor sought to solve the problem of designing a nut that is integrally molded, stable, and prevents it from falling off and rotating. Utility Model Content
