The product has two hook legs, and the overall sinking amount is determined based on the three-dimensional height of the hook legs during welding. Two hook feet are welded to the PCB board. The tail is equipped with a back cover, and the first 12 pins are inserted into the plastic body through a board, while the last 12 pins are pasted onto the plastic board through a board. When welding, the first 12 pins are soldered to the PCB board using DIP method, while the last 12 pins are soldered to the PCB board using SMT method. The buckle in front of the first 12 pins is fixed to the plastic body to prevent it from falling out. The material used in the product is environmentally friendly and high-temperature resistant LCP plastic, the outer fixed shell is made of high-strength stainless steel, and the Pin pin terminal material is high conductivity copper terminal. It can withstand repeated plugging and unplugging for over ten thousand times in terms of wear resistance life. The product supports data transmission and also supports high current and high voltage charging. The advantages of USB Type-C mainly include: supporting high current and high voltage charging, supporting bidirectional power supply, and using the USB Type-C interface can charge the device itself or power external devices; Strong scalability, USB Type-C can transmit audio and video signals.
