LINE FILTER

PROBLEM TO BE SOLVED: To sufficiently secure an insulation distance between an L-shaped terminal arranged on a terminal block and a common-mode core, and to position a normal-mode core to be inserted from a bobbin side face. SOLUTION: The line filter includes: a bobbin 10 with terminals comprising winding core parts 12 for winding a pair of windings around them, both end flange parts 13 arranged at both ends of the winding core parts 12, terminal blocks 16 arranged under the both end flange parts 13, and L-shaped terminals 18 under the terminal blocks 16; horizontal common-mode cores 40 each forming a closed magnetic circuit by inserting one magnetic leg 41 in the winding core part 12; a normal-mode core 30 magnetically coupled to the closed magnetic circuits of the common-mode cores 40, and inserted in a recessed part 15 formed on side faces of a central flange part 14; and an insulating cover 50 located between the common-mode cores 40 and the terminals 18. The cover 50 is locked to the bobbin 10 with terminals while pressingly contacting the normal mode core 30 inserted in the recessed part 15. COPYRIGHT: (C)2011,JPO&INPIT
