Chip filter and the related supplementary tool
First Claim
1. A chip filter, comprising:
- an insulative holder base, said insulative holder base comprising two opposing sidewalls, a recessed chamber defined between said two sidewalls, two arrays of protruding blocks respectively arranged along said sidewalls adjacent to said recessed chamber and protruding over a flat top edge of each of said sidewalls, a wire groove defined between each two adjacent protruding blocks of each said array of protruding blocks, a finished surface formed on the flat top edge of each of said sidewalls, and a plurality of soldering zones defined in said finished surface corresponding to said wire grooves;
a plurality of connection terminals, each said connection terminal comprising a base portion positioned in one soldering zone in said finished surface of one said sidewall of said insulative holder base, a soldering surface located on said base portion and kept in flush with the top edge of the associating sidewall, and a bonding tip extended from said base portion out of the associating sidewall for bonding to one respective surface contact of an external circuit board; and
a plurality of filter elements mounted in said recessed chamber of said insulative holder base, each said filter element comprising a metal core and a plurality of windings wound round said metal core, said windings each comprising a plurality of lead wires respectively extending out of said recessed chamber of said insulative holder base through the wire grooves of said insulative holder base and respectively soldered to the soldering surfaces of said connection terminals.
