USB memory device, USB socket for the USB memory device and printed circuit board for fabrication of the USB memory device

摘要

PURPOSE: A USB memory device, a USB socket for the USB memory device and a printed circuit board for fabricating the USB memory device are provided to prevent the wrong insertion of a USB storage device. CONSTITUTION: A mold body(130) encloses a printed circuit board to protect a semiconductor element, and includes a first mold body, a protrusion(130a) and a second mold body. The first mold body is formed at the backside of the USB terminal while exposing the USB terminal of the first plane. The protrusion unit protrudes from the edge portion of the printed circuit board at the both sides of the USB terminal. The second mold body is formed on the second plane.
