The appearance of the product is made by stretching the hardware shell. The interface of the product is an elliptical interface. The tail has 24 pin pins arranged in a symmetrical 12-12 pattern. When welding, the PCB board is clamped between symmetrical pins 12 to 12. Type-C is a part of the USB 3.1 standard, not a new standard. Its interface is lightweight and compact, and can be expanded into three interfaces: power supply/USB transmission/VGA or HDMI. Through the adapter, it can also be compatible with previous generation interfaces such as USB3.0 and USB2.0. The most intuitive advantage of USB Type-C is that it allows us to completely reduce the hassle of inserting cables, eliminating the need for component damage caused by incorrect insertion or errors. 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 PD chargers, wireless chargers, car chargers, mobile power supplies, TWS Bluetooth headphones, consumer electronics and other devices.
