Abstract
An electromagnetic interference filter has an input socket, an insulated base, an insulated upper cover, a metal case, an L-shaped, elongated ground terminal, two short output terminals, a grounded bridge hook, two spring plates and the internal circuit elements. The two spring plates are fitted into openings on the upper and lower surfaces of the metal case which covers the insulated base. An oblique protruding block on either side of the input socket penetrates through a square hole on either side of the metal case to couple the case to the input socket. Upwardly oblique extending spring plates are provided on both of the upper and lower surfaces of the metal case which spring plates are pressed against casing walls to hold the assembly firmly and stably immobilized onto the casing walls.
