[0002] At present, in all aspects of people's daily life, in order to achieve the connection between electrical input and output, electrical connectors are often used. Common ones include plugs, sockets, and MC connectors. These connectors have different numbers of contacts according to the number of phases of transmitted power or current. These electrical connectors are widely used in various electronic products and are the main functional components of electronic products. Common electrical connectors generally include male and female ends. When the male and female ends are connected together, the electrical connection is connected, and when the male and female ends are separated, the electrical connection is disconnected. With the development of electronic technology, circuit structures are becoming increasingly complex, and the corresponding electrical connector structures are also becoming increasingly complex. In some applications of electrical connectors, it is required that the male and female ends can rotate relative to each other.

[0003] For example, the patent document with publication number "CN209658446U" discloses a rotary connector, comprising a male socket and a female socket, wherein the male socket is sleeved within the female socket and rotates relative to the female socket; a metal spring is provided on the male socket, and a metal sheet and a groove are provided on the female socket; the male socket and the female socket have a first position and a second position, and when the male socket is in the first position, the metal spring is in elastic contact with the metal sheet, and when the male socket is rotated to the second position, the metal spring is located in the groove, and the metal spring and the metal sheet are loosened and disengaged. However, this patented technical solution has many parts and components, and assembly is relatively cumbersome. In particular, if some smaller parts are lost, the specific implementation of the patented technical solution will be affected. Utility Model Content
