Abstract:
A line filter of the invention is to sufficiently ensure an insulation distance between an L-shaped terminal and a common mode magnetic core equipped on a terminal platform, and furthermore position a normal mode magnetic core which is inserted from a side surface of a winding tube. The line filter is provided with the following components: a terminal-equipped winding tube (10) which comprises a core winding part (12) coiled by a pair of coils, two end flanges (13) provided at two ends of the core winding part (12), the terminal platform (16) provided below the two end flanges, and an L-shaped terminal (18) provided below the terminal platform; a transversely equipped common mode magnetic core (40) which inserts one magnetic pin (41) into the core winding part and form a closed magnetic path; the common mode magnetic core (30) which is magnetically coupled with the closed magnetic path of the common mode magnetic core and is inserted into a recess (15) that is provided at a side surface of a middle flange (14); and an insulative cover (50) which is provided between the common mode magnetic core and the terminal and is blocked with the terminal-equipped winding tube (10) when the normal mode magnetic core which is inserted into the recess is jointed through pressure joint.
