[0019] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0020] like Figure 1-2As shown, an inductor structure for use in heating, ventilation, and air conditioning systems comprises a base 1 and an inductor body. The inductor body is secured to the base 1 and includes a magnetic core (not shown) and at least two sets of coil windings 2 wrapped around the core. The lead ends and lead ends of the coil windings 2 extend downwardly from the base 1. In this embodiment, there are three sets of coil windings 2. Of course, the number of coil windings 2 can be increased to four or five sets based on actual needs, and the magnetic core is correspondingly larger. Compared to existing multiple inductors, while providing the same conversion power, this inductor structure is smaller and less expensive, thus saving space. The magnetic core is secured to the base 1 via a mounting housing 3. Positioning slots 4 are provided on the base 1 for positioning the coil windings 2. This design improves the reliability of the inductor and effectively prevents lead wires from dangling or shifting. The positioning slots 4 are preferably arc-shaped.

[0021] Furthermore, a mounting cavity is provided in the mounting housing 3, through which the magnetic core is placed, and the mounting cavity is adapted to the shape of the magnetic core. The mounting housing 3 is made of plastic, which can reduce costs.

[0022] Furthermore, a partition 5 is provided between the coil winding 2 and the adjacent coil winding 2. Correspondingly, a positioning block 30 for positioning the partition 5 is provided on the mounting shell 3. The positioning blocks 30 are grouped in two, and slots for fixing the partition 5 are formed between the two blocks, which facilitates workers to assemble quickly and improves assembly efficiency.

[0023] In this embodiment, if Figure 2 As shown, the base 1 is provided with a left mounting slot 6 and a right mounting slot 7 on either side, respectively. The opening of the left mounting slot 6 faces the opening of the right mounting slot 7, and the mounting housing 3 is secured to the base 1 via these slots. Each of the left and right mounting slots 6 and 7 is provided with a slide 8 and an elastic clip 9. The slide 8 runs along the height of the left or right mounting slot 6 or 7; in other words, the slide 8 extends vertically. The elastic clip 9 is located at the top of the left or right mounting slot 6 or 7, facilitating downward fastening of the mounting housing 3 to the base 1. Correspondingly, a slider 31 and a clamping block 32 are provided on the outer wall of the mounting housing 3. The slider 31 slides in conjunction with the slide 8, while the clamping block 32 clamps in conjunction with the elastic clip 9. The right end of the clamping block 32 is connected to the top of the slider 31, and the clamping block 32 is perpendicular to the slider 31. The slider 31 and the clamping block 32 can be integrated to facilitate demolding.

[0024] Furthermore, a reinforcement plate (not shown in the figure) is provided at the bottom of the base 1 , and the reinforcement plate increases the strength of the base 1 .

[0025] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
