The utility model has the beneficial effects that:

according to the utility model, the heat dissipation support column with the heat dissipation groove is arranged at the lower end of the base, so that a gap is reserved at the bottom of the inductor after the inductor is welded on the circuit board, natural wind can circulate from the gap, and heat generated when the inductor is electrified is taken away, and the heat dissipation performance of the plug-in inductor is improved.

Furthermore, the number of the heat dissipation support columns is two, and the two heat dissipation support columns are respectively located at the left end and the right end of the base. The heat dissipation support column is equipped with two, can better keep the balance of inductance installation when the welding.

Further, copper line winding is equipped with two sets ofly, and is a set of copper line winding twines the left end installation of magnetic core, another group copper line winding twines the right-hand member installation of magnetic core, the mid-mounting of magnetic core has insulating division board, insulating division board is installed two sets of copper line winding's centre. When the plug-in inductance is the common-mode inductance, an insulating isolation plate is arranged between the two groups of copper wire windings, so that the two groups of copper wire windings are prevented from being in physical contact.

Further, both ends all are equipped with copper line mounting groove around the base, the lower extreme of base corresponds the position installation of copper line mounting groove the stitch, copper line winding inlays in the copper line mounting groove, both ends around winding respectively at the both ends of copper line winding the stitch is connected. Two with the end be equipped with compatible copper line mounting groove between the copper line mounting groove. Copper wire winding can combine the position that changes the stitch according to the specification of circuit board, selects copper wire mounting groove or compatible copper wire mounting groove.
