Static electricity eliminating structure for electronic devices

Abstract

Abstract A static electricity eliminating structure for an electro­nic device to be connected to a main device, comprises an electronic device (1) including a circuit board having in­put/output terminals and an IC chip mounted thereon, an up­per and a lower metallic panel (6) sandwiching said circuit board therebetween through insulating spacers, said panels having printing surfaces and being electrically connected together through a built-in conductor member, said electro­nic device (1) further including a metallic surface portion (16) provided on the surface of either said upper or lower panel (6), said metallic surface portion (16) being elec­trically connected to said upper or lower panel (6), and a connector (20) of a main device to which said electronic device (1) is connected, said connector having a resilient static electricity eliminating terminal (25) which is lon­ger than connector terminals (21) of said connector and co­mes into contact at its distal end with said metallic sur­face portion (16) of the electronic device (1), so that when said electronic device is connected to said connector, the distal end of said static electricity eliminating ter­minal (25) is brought into press-contact with said metallic surface portion (16) of said electronic device (1). When the electronic device is connected to the connector, the distal ends of the terminals (25) are brought into press­contact with the metallic surface portions (16) before the input/output terminals are connected to the connector ter­minals of the connector, thereby enabling a satisfactorily high contact pressure and a satisfactorily large contact area to be obtained.
