[0029] Refer to Figure 1, A coil structure includes: a winding body 200, leads 250, and a housing 100; the leads 250 are formed at the ends of the winding body 200, the leads 250 can be electrically connected, and the winding body 200 is electrically connected to the outside through the leads 250; within the same cross-section of the leads 250, there are at least two staggered radial directions with different radial dimensions; the housing 100 is sleeved outside the winding body 200 and the leads 250, the leads 250 are in contact with the housing 100, and the housing 100 can be electrically connected to the outside. The winding body 200 is electrically connected to the housing 100 through its leads 250, and the housing 100 is electrically connected to the outside. Therefore, the inductor can be electrically connected to the circuit through its housing 100 and perform circuit processing operations through the winding body 200, thus successfully completing the work of the inductor in the circuit. Since the leads 250 are electrically connected to the housing 100 within the housing 100 and the inductor is electrically connected to the outside through the housing 100, the relatively fragile leads 250 are protected within the housing 100. Therefore, the inductor can be more stably and reliably electrically connected to the outside, and the problem of inductor failure caused by damage to the leads 250 can be avoided.

[0030] In some embodiments, referring to Figure 3 , the leads 250 are flat and elongated in shape, and the leads 250 extend in a direction away from the winding body 200. The flat and elongated leads 250 can effectively increase the contact area 270 for contacting the housing 100. Therefore, the electrical connection effect between the winding body 200 and the housing 100 can be smoothly achieved through the leads 250, and further ensure that it can be smoothly connected to the circuit and operate.

[0031] It can be envisioned that the cross-sectional shape of the leads 250 can be rectangular or kidney-shaped, and the length dimension of the leads 250 is greater than its width dimension. The specific implementation can be adjusted according to actual needs and is not limited here.

[0032] In some embodiments, referring to Figure 3 , the side of the leads 250 has a contact surface 270, and the contact surface 270 abuts against the inner wall of the housing 100. The abutting effect between the contact surface 270 and the inner wall of the housing 100 can enable the leads 250 to smoothly contact and be electrically connected to the housing 100. Moreover, the contact surface 270 can also effectively increase the contact area 270 between the leads 250 and the housing 100, thereby further ensuring that the leads 250 can be smoothly electrically connected to the housing 100, facilitating the winding body 200 to be connected to the circuit and operate.

[0033] In some embodiments, referring to Figure 3, the contact surface 270 is a plane, and the contact surface 270 fits against the inner wall of the housing 100. The planar contact surface 270 can not only effectively increase the contact area between the pin and the housing 100, but also effectively improve the contact stability between the pin and the housing 100. Therefore, more stable contact and conduction operations can be carried out between the pin and the housing 100.

[0034] Specifically, the cross-sectional shape of the pin is rectangular, and the contact surface 270 is the widest plane among the outer sidewalls of the pin.

[0035] In some embodiments, referring to Figure 2 , the contact surface 270 and the remaining side portions of the pin 250 are in arc transition. The arc transition enables the pin and the housing 100 to reduce the stress concentration problem caused by each other through the arc transition when the pin and the housing 100 undergo relative shaking or crosstalk, thereby effectively slowing down or avoiding the loss between the pin 250 and the housing 100 during relative movement.

[0036] In some embodiments, referring to Figure 1 , a conductive portion 150 is provided on the sidewall of the housing 100, and the conductive portion 150 can electrically connect the inner and outer sides of the housing 100; the pin 250 is in contact with the conductive portion 150. The conductive portion 150 can electrically connect the inside and outside of the housing 100. Therefore, the housing 100 does not need to be made entirely conductive, and only through the conductive portion 150 for electrical connection can the effect of electrically connecting the inside and outside of the housing 100 be achieved, thereby effectively avoiding the problem of short circuit when other parts of the housing 100 come into contact with the winding body 200 or the pin 250.

[0037] Specifically, the conductive portion 150 is made of a conductive metal material, and the remaining parts of the housing 100 are made of an insulating material such as plastic.

[0038] In some embodiments, referring to Figure 2 , there are two pins 250 which are respectively formed at both ends of the winding body 200, and both pins 250 are electrically connected to the housing 100. The two pins 250 can be respectively used as the electrical positive and negative poles of the winding body 200 to be electrically connected to the housing 100, so that the winding body 200 of the inductor can be completely connected to the circuit and can smoothly operate in the circuit.

[0039] In some embodiments, referring to Figure 1, there are two conductive parts 150, which are respectively located on both sides of the housing 100, and the pins 250 and the conductive parts 150 are in one-to-one correspondence and are in contact with each other. Since the conductive parts 150 are located on both sides of the housing 100, the housing 100 can be electrically connected to the circuit through its two sides. Therefore, the electrical connection of the housing 100 can be made more orderly and the connection position can be easily distinguished, which is convenient for the use of the inductor.

[0040] In some embodiments, referring to Figure 1 , the conductive part 150 and the pin 250 are fixedly connected to each other by magnetic attraction, adhesive or snap. Connection methods such as magnetic attraction, adhesive or snap can effectively fix the conductive part 150 and the pin 250 to each other, thereby effectively improving the working stability of the pin 250, and further ensuring that the inductor can work smoothly and stably.

[0041] A second aspect of the present invention provides an embodiment of an inductor, including the above coil structure. The winding body 200 is electrically connected to the housing 100 through its pins 250, and the housing 100 is electrically connected to the outside. Therefore, the inductor can be electrically connected to the circuit through its housing 100 and perform circuit processing operations through the winding body 200, so as to successfully complete the work of the inductor in the circuit. Since the pins 250 are electrically connected to the housing 100 inside the housing 100, and the inductor is electrically connected to the outside through the housing 100, the relatively fragile pins 250 are protected inside the housing 100. Therefore, the inductor can be more stably and reliably electrically connected to the outside, and the problem of inductor failure caused by damage to the pins 250 can be avoided.

[0042] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0043] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
