The appearance of the product is made by riveting the hardware shell, and the riveting seam is in the middle of the product. The interface of the product is an elliptical interface. The characteristic of Type-C male is that it does not distinguish between positive and negative. Because the 24 pins of this interface are symmetrically distributed in the contact function. Thus, both forward and reverse insertion can be achieved, and the device can successfully recognize and achieve full functional operation. The bottom of the product is fixed with a small buckle and a plastic body. It belongs to the upright type-c24p male head, with three legs at the bottom, and is welded to the PCB board during welding. It supports high current charging and data transmission. The product adopts the 3.1 standard. Compared with the USB2.0 interface adopted by earlier smart computers, the transmission speed is much higher, and the maximum data transmission speed can reach 10Gbit/s. And type-c supports the USB-PD power supply standard, with a maximum power supply of up to 100 watts. The tail has 24 pin pins, which are arranged symmetrically from 12 to 12 in a neat manner. When welding, weld with the PCB board SMT board. 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.
