Connectors are an indispensable component in electronic equipment. If you follow the path of current flow, you will always find one or more connectors. The form and structure of connectors are ever-changing. There are various forms of connectors depending on the application object, frequency, power, application environment, etc. In general, connectors are not limited to current. In today's rapidly developing optoelectronic technology, in optical fiber systems, the carrier for transmitting signals is light. Glass and plastic replace the wires in ordinary circuits, but connectors are also used in optical signal paths, and their functions are the same as those of circuit connectors.

The end of the rotating ring 22 away from the male head 10 is provided with a second annular limiting protrusion 222, and the second annular limiting protrusion 222 is composed of a plurality of protrusions. One end of the elastic member 23 abuts against the second annular limiting protrusion 222, and the other end of the elastic member 23 abuts against the first annular limiting protrusion 211, so as to limit the elastic member 23 together with the first annular limiting protrusion 211 and the second annular limiting protrusion 222.

[0054] The outer peripheral side wall of the first annular limiting protrusion 211 is recessed with a through groove 212 extending in the axial direction and penetrating through both sides of the first annular limiting protrusion 211. There are several through grooves 212. The side of the first annular limiting protrusion 211 away from the male head 10 is recessed with a limiting groove 213 extending in the circumferential direction.
