[0013] The width of the clamping portion is greater than the insertion width of the clamping slot, one end of the clamping portion is fixedly connected to the insertion portion, and the other end of the clamping portion is fixedly connected to the plug board.

[0014] The two sides of the inserting portion are fixedly provided with protrusions. When installing or removing, the protrusions can be pinched to increase the convenience of installation and removal.

[0015] Insulating paper is provided on the iron core at a location corresponding to the winding of the coil.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Compared with ordinary pin reactors, this application does not require a skeleton, uses insulating paper for insulation, and has an injection-molded base, which is low in cost and small in size;

[0018] The pins are designed to be detachable, and the corresponding current-carrying pins can be replaced according to the current size. BRIEF DESCRIPTION OF THE DRAWINGS
