[0002] A connector, also called a plug-in connector, is a device used to connect two active devices and can transmit current or signals. Connectors are divided into male connectors and female connectors, which are generally also called connectors and sockets respectively. A simple circuit structure, such as a conductive terminal, a PCB board and other circuit carriers, is usually arranged inside the connector. During the use process, external electromagnetic signals are likely to interfere with the internal circuit of the connector, affecting the reliability of signal transmission. Therefore, a shielding case is usually added outside the connector to resist external electromagnetic interference. The shielding case is mostly made by die-casting forming process. The traditional die-casting mold for the shielding case is relatively large in size, including an upper mold and a lower mold. During use, the upper mold and the lower mold need to be assembled together first and fixed by fasteners, with cumbersome operation and low efficiency.
