Background technique

Nowadays, electronic devices are connected to electronic computers through a variety of electrical connectors to perform data transmission. Universal Serial Bus (USB) electrical connectors with high transmission speed are widely used. The USB Type-C designed based on the USB3.1 specification has a slimmer design, faster transmission speed and stronger power transmission, and supports double-sided insertion.
