The interface of Type-C male is an elliptical interface. From the appearance of the interface, the biggest feature 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. In order to achieve both forward and reverse insertion, the device can successfully recognize and achieve full functional operation. The outer shell is riveted to form a plastic body inside the package, with a small buckle at the bottom fixed to the plastic body. The product is the latest USB interface appearance standard, and its volume is smaller than that of Tpe-A and Type-B. In addition, Type-C is an interface type that can be applied to both PC (master device) and external devices (slave devices, such as mobile phones). There are two pins at the tail, which are welded to the PCB board during welding. There are also 24p pins, which are arranged symmetrically and neatly on the plastic body in a 12-12 pattern, and are welded to the PCB board during welding. 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 24pin pin pin with high conductivity copper. 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. It can withstand repeated plugging and unplugging for over ten thousand times in terms of wear resistance life.
