[0002] Connectors are also called connectors. Also known as headers and sockets in China, they generally refer to electrical connectors. These are devices that connect two active components, transmitting current or signals. Connectors simplify the assembly and mass production of electronic products. They also facilitate repairs; if an electronic component fails, a connector allows for quick replacement. They also enhance design flexibility, giving design engineers greater flexibility when designing and integrating new products and assembling systems from components. Currently, the most widely used connector is the USB connector, with the most popular being USB Type-C. USB Type-C, abbreviated as Type-C, is a hardware interface specification for the Universal Serial Bus (USB). The Type-C connector's strengths include a slimmer design, transfer speeds of up to 10Gbps, and powerful power delivery of up to 100W. Its most notable feature is its reversible USB interface.

However, most connector shells on the market are stamped shells. The strength of stamped shells is easily damaged after being subjected to high-intensity swing and pulling forces. Stamped shells are also prone to desoldering from the circuit board, which shortens the service life of the connector. Therefore, it is necessary to improve the existing connectors.
