Ground Finger Device for Shelf for Electronic Communication Equipment

摘要

The present invention relates to a ground finger device of a shelf for an electronic communication device, and has a purpose to prevent the failure of the system by blocking the harmful electromagnetic waves generated in the equipment by allowing the printed circuit board to contact the support of the shelf evenly.;In order to achieve the above object, it is divided into the front support portion 41 and the rear support portion 42, each support portion (41, 42) and the support 40 having an insertion groove (41a, 42a); Nut strips 20 and 20 'inserted into the insertion grooves 41a and 42a of the front support part 41 or the rear support part 42; A front finger consisting of a bottom portion 11, a side portion 12, a mounting guide portion 13, a tension portion 14, and a support guide portion 15 so as to be fixed to the nut strip 20 of the front support portion 41. 10; Rear finger (10 ') consisting of a bottom portion (11'), a side portion (12), a mounting guide portion (13 '), and a tension portion (14') to be fixed to the nut strip (20 ') of the rear support portion (42). );Therefore, by blocking harmful electromagnetic waves generated in the equipment by maintaining a stable ground state of the printed circuit board, there is an effect of preventing the failure of the system, there is an effect that the mounting operation of the printed circuit board is also easily made.
