Background

Nowadays, electronic devices are connected to an electronic computer through various electrical connectors to perform data transmission, and universal serial bus (Universal Serial Bus, USB) electrical connectors with fast transmission speed are widely used. The USB Type-C designed based on the USB3.1 specification has a thinner design, a faster transmission speed and a stronger power transmission, and supports double-sided insertion.
