Signal filter module

A signal filter module, comprising an electrically insulative housing, a plurality of metal terminals installed in said electrically insulative housing at two opposite sides for bonding to an external circuit board, and a plurality of filter elements mounted inside said electrically insulative housing and electrically connected to said metal terminals, wherein:

• said electrically insulative housing has a plurality of protruding blocks respectively protruded from a bottom edge of each of two opposite vertical sidewalls thereof and a wire groove defined between each two adjacent protruding blocks at each of said two opposite vertical sidewalls;
• said metal terminals each have a base partially embedded in one of the vertical sidewalls of said electrically insulative housing and a bonding tip extended from one end of said base and suspending outside said electrically insulative housing for bonding to an external circuit board, said base having a bonding surface exposed to the outside of the bottom edge of the associating vertical sidewall of said electrically insulative housing;
• said filter elements each have a plurality of coils wound thereon, each said coil having a lead end inserted through one said wire groove of said electrically insulative housing and bonded to the bonding surface of the base of one said metal terminal.
