PURPOSE:To prevent an obstruction giving to other circuits within an electric device by a method wherein the entire surface of an insulating portion except for a surface where a connecting pin is prevent is sealed with a metallic plate and a hole for passing the connecting pin is formed in a surface connection to a metallic printed substrate. CONSTITUTION:The entire surface of an insulating portion except for a surface a connecting pin 3 of a connector 2 for a printed substrate is prevent is sealed with a metallic plate 1 and a hole 5 for passing the connecting pin 3 is arranged in a surface connecting to a printed substrate 4 of the metallic plate 1 so that the connecting pin 3 may be fitted into the printed substrate 4. Therefore, obstructive signals mixed from the connecting pin 3 of a sealed connector do not influence each circuit inside an electric device, and further the connector 2 for the printed substrate is grounded by a chip type capacitor 7 on the rear side of the printed substrate, whereby the obstructive signals escape into the ground. Thus, an obstruction giving to other circuits within the electric device disappears. |
