The outer shell of the product is made of high-strength stainless steel with hardware. The appearance is synthesized by riveting. The interface of the micro USB 3.0 motherboard is a B-type interface with rolled edges. There are two pins in the middle and a small rectangular pin at the tail. When welding, the two pins in the middle and the tail pins are welded to the PCB board, which can provide good fixation. There are 10 pin pins at the bottom, placed in half or five separate positions. When welding, the 10 pin SMT is attached to the PCB board. The internal terminals are made of environmentally friendly and high-temperature resistant LCP plastic, and the 10 pin pins are made of high conductivity copper. When installing the micro USB socket, be careful not to place it next to high temperatures or directly install it on combustible objects to avoid natural phenomena such as the USB socket being prone to fire. It can withstand repeated plugging and unplugging for over ten thousand times in terms of wear resistance life.
