(A) Technical Field: the present invention relates to a technique for reducing static electricity generated by electrical friction or contact friction of a USB. (B) Problem to be solved: In most existing movable USBs which are currently used, electric impact is applied to a USB, data disappears, a prevention device for the data disappearance is not prepared, and thus the present invention is to prevent electrical impact and the occurrence of a magnetic field and static electricity at the time of contact of the movable USB. (C) Resolution Means of Problem: According to the present invention, an insulating material is introduced to the existing USB chip, a chip portion is packed with rubber that is an insulating material, and static electricity occurring in a junction conductor is prevented from being applied to the chip, thereby preserving data stored in the chip. (D) Effect: According to the present invention, data loss caused by electrical impact or the occurrence of static electricity that is a weakness of USBs hitherto is prevented, the erroneous operation of a USB caused by static electricity is also prevented, and it is reasonable for the user to expect protection against the loss of important data. |
