[0002] With the continuous development of today's society and the electronic and electrical industry, connectors, namely CONNECTOR, are also known as connectors, plugs and sockets in China. They generally refer to electrical connectors, that is, devices that connect two active devices, so that current or signals can flow from one conductor to another. In simple terms, electronic connectors are components used to complete the electrical connection between circuits or electronic machines, etc., and become connectors, that is, bridges between the two. The form and structure of connectors are ever-changing. With different application objects, frequencies, powers, application environments, etc., there are various forms of connectors, and the contact pieces, that is, contact terminals, on all connectors are used to connect the circuits.

[0003] A conventional connector usually includes an insulating seat and a plurality of terminals, wherein the plurality of terminals are integrally formed or inserted into the insulating seat to realize an assembled connection between the terminals and the insulating seat; however, the structural strength of the existing terminals on the insulating seat is poor. When the connector is pulled or the terminals of the connector are plugged in and out for a long time, the terminals and the insulating seat are prone to loosening, thereby affecting the use of the conductive connection between the terminals and other components, resulting in poor stability in use, reducing the service life of the connector, and having a small scope of application.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
