[0041] The utility model improves the above wiring structure.

[0042] Reference Figures 2 to 6 , provide a kind of inductor, several coil slots 101 are arranged in the interior of shell 1, one inductive coil 3 is installed in each coil slot 101. In the embodiment, inductive coil 3 is annular coil, shell 1 has five coil slots 101. Five coils, two as rectifier coil, three as inverter coil.

[0043] In the utility model embodiment, part of inductive coil 3 is arranged in coil slot 101 in first direction, part of inductive coil 3 is arranged in coil slot 101 in second direction. For example, three inverter inductors are arranged in horizontal direction, and two rectifier inductors are arranged in vertical direction.

[0044] Each inductive coil 3 includes a magnetic core and a winding, and the two ends of the winding are respectively a lead-in end and a lead-out end.

[0045] In order to solve the problem of inductive coil 3 lead-out, the structure of terminal assembly and terminal column 402 is designed.

[0046] Combined with reference Figure 5As shown in the local enlarged view, the terminal assembly comprises a main plate 401 and terminal posts 402 arranged on the main plate 401. The main plate 401 is fixed outside the shell 1, for example, can be fixed on the outer end face of the shell 1, i.e. the end face close to the appearance side of the inductor coil 3. The incoming and outgoing ends of each inductor coil 3 correspond to a terminal post 402; wherein the terminal post 402 is a protruding column structure arranged on the surface of the main plate 401, and the terminal post 402 is used to assist the wiring of the inductor coil 3.

[0047] The incoming and outgoing ends of each inductor coil 3 correspond to a terminal post 402; wherein the terminal post 402 is a protruding column structure arranged on the surface of the main plate 401, and the terminal post 402 is used to assist the wiring of the inductor coil 3.
