USB Connector (Universal Serial Bus) is a widely used interface in modern electronic devices, supporting data transfer, power supply, and connecting various devices such as mobile phones, computers, printers, and more. There are various types of USB Connectors, including Type-A, Type-B, Micro USB, and the latest Type-C. Type-C, with its reversible plug design, compact form, and faster transfer speed, is gradually becoming the mainstream standard and is widely used in various smart devices.

Since its inception, the USB Connector has undergone multiple upgrades, with transfer speeds evolving from the original USB 1.0 to the current USB 4.0, supporting data transfer rates of up to 40Gbps. In addition to data transfer, modern USB connectors also support device charging, especially in mobile devices and laptops. The introduction of the USB PD (Power Delivery) protocol enables the connector to provide power for high-power devices, promoting the simplification and portability of device design.
