Plating button electrostatic inflow countermeasure of video cassette recorder

摘要

The present invention relates to a plated button electrostatic inflow counterpart of a video cassette recorder, and a plated button structure that combines a plated knob with a conventional operation unit has a separate plated knob when a plurality of buttons such as a function button are to be installed. This necessitates more management points due to an increase in the number of parts, a higher manufacturing cost, and fusion and fixation of the plated knob, which requires a lot of work time during assembly, thereby reducing productivity. In addition, the masking coating type plating button structure is easy to apply only to the hinge type button, and is difficult to apply to the straight type button, and the masking liquid has a viscosity of the masking liquid so that it is always in a constant state when avoiding plating by a certain distance required by static electricity. There are many problems, such as difficulty in managing, the present invention is the main frame A ground plate having a tension that is pressed against the support boss formed at the rear of the support member for supporting the plurality of plating buttons is installed on the bonded printed circuit board to ground the static electricity introduced through the plating button through the support boss. It can be grounded in a stable state through the copper foil circuit ground on the back of the printed circuit board in contact with the plate to prevent the product from malfunctioning or falling down in advance. It is possible to improve the productivity by.
