The interface of the product is an elliptical interface, with two hook legs welded to the PCB board during soldering, and the overall sinking is 0.8mm, which is 0.8mm below the PCB board or 0.8mm below the broken board. The tail has two pins that are welded to the PCB board. There are two positioning columns next to the two pins, which play an overall positioning role during welding but not a fixing role. The 24 pin pins are arranged symmetrically and neatly from 12 to 12, with the first 12 pins and the last 12 pins attached to the plastic body and welded to the PCB SMT board.

The advantages of USB interface mainly lie in three aspects. Firstly, the most intuitive one is convenient plugging and zero error. Secondly, the Type-C interface takes up less internal space of the phone, which can further reduce the thickness of the phone. But the main advantages of Type-C are still in terms of transmission speed and output power. In theory, Type-C supports a 3.1 standard transmission speed of up to 10Gbps, supports a maximum output power of 100W, and can achieve bidirectional power supply (charging oneself while supplying power to external devices).
