USB MEMORY HAVING A MICRO 5 PIN

摘要

PURPOSE: A USB memory with a micro 5 pin is provided to facilitate the storage and sharing of various types of data into a memory chip by using the existing USB port on an electronic device. CONSTITUTION: A memory chip (20) is fixed on a separate floating ball (40) which slides from a case (10). The floating ball emerges from the case through a guide groove (11) formed at the end of one side of the case. If the memory chip protrudes from the case by the floating ball, the memory chip and the circuit board (31) of a micro 5 pin (30) are short-circuited to each other. If the memory chip is dented into the inside of the case by the floating ball, the memory chip and the circuit board of the micro 5 pin are connected to each other.
