STATIC ELECTRICITY INVASION PREVENTION MECHANISM OF ELECTRONIC COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a static electricity invasion prevention mechanism of an electronic component in which, even if operated by a finger or the like which is charged, noises due to static electricity does not enter into its electric circuit.;SOLUTION: The electronic component is equipped with a case 130 having an opening part 131 and an electronic component main part (made of a first circuit board 20 or the like provided with a sliding molding 50, a slider 70, and a switch pattern 23) which is installed at the lower part of the case 130 and is operated from the upper side of the case 130 through the opening part 131. A grounding plate 80 having conductivity which makes enter the static electricity invading from the opening part 131 of the case 130 is fitted so as to cover the upper face of the sliding molding 50. A conductor pattern 33 is provided which, by contacting a sliding part 85 (elastic sliding part 87) of the grounding plate 80, leads out the static electricity entered from the upper part of the case 130 to the grounding plate 80 through the opening part 131 from the grounding plate 80.;COPYRIGHT: (C)2006,JPO&NCIPI
