    • A peripheral card includes a two-part metal cover mounting a printed wiring board on a U-shaped plastic frame. The wiring board is spaced from inside surfaces of the cover preferably by a pair spring clips mountable on side edges of the wiring board, each clip having an apertured intermediate bight portion overlying and in aperture burr scraped contact with ground contact pads on the board. Barbed-end spring fingers extend integrally from the bight portion preferably toward the board side edge to which it affixed and into scraped contact with respective ones of the metal cover parts as the metal cover parts are assembled together. The clips hold the board from movement in the cover and electrically ground any static electrical charges on the metal cover parts to the contact pads and to a ground socket in the frame, and electrically ground the metal cover parts to provide electromagnetic shielding of the electrical circuitry on the wiring board.
    • 外围卡包括两个部分的金属盖,将印刷电路板安装在U形塑料框架上。 布线板优选地由安装在布线板的侧边缘上的一对弹簧夹与盖的内表面间隔开,每个夹具具有一个有孔的中间弯曲部分,并且与该板上的接地触点焊接在一起。 随着金属盖部件组装在一起,棘爪部分的弹簧指状件优选地从弯曲部分一体地延伸到其固定的板侧边缘并与相应的金属盖部分刮擦接触。 夹子将电路板保持在盖子的运动中,并将金属盖部件上的任何静电电荷电接地到框架中的接触垫和接地插座,并且电接地金属盖部件以提供电路的电磁屏蔽 在接线板上。
