The interface of the product is an elliptical interface, and the surface is made of a metal shell by stretching. There are two pins and 24pin pins at the tail, and the 24pin pins are arranged in a symmetrical 12-12 pattern. When welding, the PCB board is clamped in the middle of the 12 to 12 symmetrical pins. The product supports charging and data transmission. The maximum transmission rate of the USB-C port is 15Gb/s, which has good scalability and can connect to other devices. It can also connect to external displays, and the interface bandwidth is large enough. Due to technological innovation, Type-C can occupy less circuit board space, which does not have much practical change or significance for us. However, for hardware product designers, small changes can bring more possibilities and changes to the internal layout in the future. The product is made of high-strength stainless steel as the hardware shell, environmentally friendly and high-temperature resistant LCP plastic as the plastic body, and high conductivity copper as the pin. It can withstand repeated plugging and unplugging for over ten thousand times in terms of wear resistance life. The product is widely used in various 3C digital devices such as mobile phones, digital cameras, MP3 players, DVDs, electronic toys, mobile power supplies, etc.
