Existing Micro-SD cards have limited functionality and their components are easily damaged during insertion and removal, making them difficult to manufacture into a thin sheet shape.
The device adopts a structural design consisting of a memory card body, an upper cover, and a lower cover. The memory card body is located inside the box formed by the upper and lower covers. The edge of the window is thinner than the thickness of the upper cover. It is equipped with a partition, a latch, and a guide to prevent damage during insertion and removal. The upper and lower covers are connected by ultrasonic welding.
This design allows the memory card to be made into a flat surface, while also preventing damage to components during insertion and removal, thus preventing short circuits and loss of signal transmission.
