[0032] Reference Figure 1 pride Figure 5An embodiment of the utility model provides a coil, which includes a coil body 100, the coil body 100 is columnar, and the coil body 100 is formed by winding an electric wire 110 layer by layer from the inside to the outside. The number of layers of the coil body 100 is 2N, N is an integer and N≥1; wherein the two pins 120 of the coil body 100 are both located at the same end of the coil body 100.

[0033] In the above structure, the coil body 100 is formed by winding the electric conductor 110 layer by layer from the inside to the outside, and the number of layers of the coil body 100 is 2N, N is an integer and N≥1, that is, during production, the electric conductor 110 is wound layer by layer in an even number of layers from the inside to the outside to form the coil body 100, thereby enabling the two pins 120 of the coil body 100 to be located at the same end of the coil body 100, thereby reducing the height difference between the two pins 120, and making the subsequent power connection operation of the two pins 120 simpler and more convenient, and reducing the risk of damage to the pins 120 due to excessive height difference caused by the two pins 120 being located at the two ends of the coil body 100, thereby causing the subsequent power connection operation to be too complicated.

[0034] It is understandable that, referring to Figures 1 to 5 In the above structure, the thread rotation direction of the electrical conductors 110 in the odd-numbered layers is opposite to the thread rotation direction of the electrical conductors 110 in the even-numbered layers.

[0035] Specifically, refer to Figure 1 and Figure 2 In some embodiments, N=1, that is, the number of layers of the coil body 100 is 2, and the coil body 100 can be specifically formed by firstly spirally winding the electric wire 110 along the direction from top to bottom, and then spirally winding along the direction from bottom to top, that is, the coil body 100 includes two layers of spiral windings, the first layer of spiral winding 101 is formed by spirally winding the electric wire 110 along the direction from top to bottom, and the second layer of spiral winding 102 is formed by spirally winding the tail end of the first layer of spiral winding 101 along the direction from bottom to top. At this time, the head end of the first layer of spiral winding 101 is located at the upper end of the coil body 100, which can be used as One of the pins 120 of the coil body 100, the tail end of the second layer spiral winding 102 is also located at the upper end of the coil body 100, and can serve as another pin 120 of the coil body 100. As a result, the two pins 120 of the coil body 100 can be located at the upper end of the coil body 100, thereby reducing the height difference between the two pins 120, so as to facilitate the subsequent power connection operation of the two pins 120, and reduce the risk of damage to the pins 120 due to excessive height difference caused by the two pins 120 being located at the two ends of the coil body 100, thereby making the subsequent power connection operation too complicated.

[0036] It can be understood that when the number of layers of the coil body 100 is 2, the coil body 100 can be formed by the electric wire 110 being first spirally wound in a direction from top to bottom and then spirally wound in a direction from bottom to top, or it can be formed by the electric wire 110 being first spirally wound in a direction from bottom to top and then spirally wound in a direction from top to bottom. The utility model does not make any specific limitation on this. It is only necessary that the coil body 100 is formed by the electric wire 110 being first spirally wound in a certain direction and then spirally wound in a direction opposite to the direction. It is only necessary to ensure that the thread rotation directions of the electric wire 110 of two adjacent layers are opposite, that is, the thread rotation direction of the electric wire 110 of the odd-numbered layers is opposite to the thread rotation direction of the electric wire 110 of the even-numbered layers.

[0037] Specifically, refer to Figure 3 In some embodiments, the number of layers of the coil body 100 is 2. The coil body 100 can be specifically formed by firstly spirally winding the electric wire 110 in a direction from bottom to top, and then spirally winding in a direction from top to bottom. That is, the coil body 100 includes two layers of spiral windings. The first layer of spiral winding 101 is formed by spirally winding the electric wire 110 in a direction from bottom to top, and the second layer of spiral winding 102 is formed by spirally winding the tail end of the first layer of spiral winding 101 in a direction from top to bottom. At this time, the head end of the first layer of spiral winding 101 is located at the lower end of the coil body 100 and can be used as a coil. One of the pins 120 of the main body 100, the tail end of the second layer of spiral winding 102 is also located at the lower end of the coil body 100, and can serve as another pin 120 of the coil body 100. As a result, the two pins 120 of the coil body 100 can be located at the lower end of the coil body 100, thereby reducing the height difference between the two pins 120 to facilitate the subsequent power-on operation of the two pins 120, and reducing the risk of damage to the pins 120 due to excessive height difference caused by the two pins 120 being located at the two ends of the coil body 100, thereby making the subsequent power-on operation too complicated.

[0038] It can be understood that in some embodiments, N=2, that is, the number of layers of the coil body 100 is 4, that is, the coil body 100 includes four layers of spiral windings from the inside to the outside, the first layer of spiral winding 101 is formed by spirally winding the electrical conductor 110 along a top-to-bottom direction, the second layer of spiral winding 102 is formed by spirally winding the tail end of the first layer of spiral winding 101 along a bottom-to-top direction, the third layer of spiral winding is formed by spirally winding the tail end of the second layer of spiral winding 102 along a top-to-bottom direction, and the fourth layer of spiral winding is formed by spirally winding the tail end of the third layer of spiral winding along a bottom-to-top direction. At this time, the beginning end of the innermost spiral winding, i.e., the first layer of spiral winding 101, is located at the upper end of the coil body 100, and can be used as one of the pins 120 of the coil body 100. The tail end of the outermost spiral winding, i.e., the fourth layer of spiral winding, is also located at the upper end of the coil body 100, and can be used as another pin 120 of the coil body 100. As a result, the two pins 120 of the coil body 100 are both located at the upper end of the coil body 100, thereby reducing the height difference between the two pins 120, facilitating the subsequent power-on operation of the two pins 120, and reducing the risk of damage to the pins 120 due to excessive height difference caused by the two pins 120 being located at both ends of the coil body 100, which in turn makes the subsequent power-on operation too complicated.

[0039] It can be understood that when N=2, that is, the number of layers of the coil body 100 is 4, the first layer of spiral winding 101 can be formed by spirally winding the electrical conductor 110 along the direction from bottom to top, the second layer of spiral winding 102 is formed by spirally winding the tail end of the first layer of spiral winding 101 along the direction from top to bottom, the third layer of spiral winding is formed by spirally winding the tail end of the second layer of spiral winding 102 along the direction from bottom to top, and the fourth layer of spiral winding is formed by spirally winding the tail end of the third layer of spiral winding along the direction from top to bottom. At this time, the beginning end of the innermost spiral winding, i.e., the first layer of spiral winding 101, is located at the lower end of the coil body 100, and can be used as one of the pins 120 of the coil body 100. The tail end of the outermost spiral winding, i.e., the fourth layer of spiral winding, is also located at the lower end of the coil body 100, and can be used as another pin 120 of the coil body 100. As a result, the two pins 120 of the coil body 100 are both located at the lower end of the coil body 100, thereby reducing the height difference between the two pins 120, facilitating the subsequent power-on operation of the two pins 120, and reducing the risk of damage to the pins 120 due to excessive height difference caused by the two pins 120 being located at both ends of the coil body 100, which in turn makes the subsequent power-on operation too complicated.

[0040] It is understandable that when N=3, 4, 5, 6 or more, the winding method of the coil body 100 can be deduced based on the winding methods of N=1 and N=2, and the present invention does not make any specific limitation on this.

[0041] In some embodiments, the two pins 120 of the coil body 100 are located at the same height.

[0042] In the above structure, by setting the two pins 120 at the same height, the subsequent power connection operation of the two pins 120 of the coil body 100 can be facilitated, thereby reducing the risk of damage to the pins 120 due to excessive height difference caused by the two pins 120 being located at the two ends of the coil body 100, thereby causing the subsequent power connection operation to be too complicated.

[0043] In some embodiments, the two pins 120 of the coil body 100 are both oriented toward the same side of the coil body 100 .

[0044] In the above structure, by setting the two pins 120 to face the same side of the coil body 100, it can be applicable to wiring scenarios with the same wiring direction.

[0045] In some embodiments, the two pins 120 of the coil body 100 face in opposite directions.

[0046] In the above structure, by correspondingly arranging the two pins 120 to face opposite sides of the coil body 100, it can be applied to wiring scenarios with opposite wiring directions.

[0047] It is understandable that the directions of the two pins 120 of the coil body 100 can be set to be the same or opposite, and can also be set to be perpendicular to each other or arranged at any angle according to actual needs, and the present invention does not make any specific limitation on this.

[0048] Reference Figures 1 to 5 In some embodiments, the cross-sectional shape of the electrical conductor 110 is rectangular.

[0049] In the above structure, by setting the cross-sectional shape of the electric conductor 110 to be rectangular, the performance of the electric conductor 110 can be improved, the power loss can be reduced, the resistance loss can be effectively reduced, and the power transmission efficiency can be improved.

[0050] It is understandable that, in some embodiments, the cross-sectional shape of the electrical conductor 110 may also be circular, or in addition, the cross-sectional shape of the electrical conductor 110 may also be elliptical or other shapes, which is not specifically limited in the present invention.

[0051] In some embodiments, the electrical conductor 110 includes a conductor layer and an insulating layer wrapped around the outer periphery of the conductor layer, the head end of the conductor layer extends to the outside of the head end of the insulating layer and forms one of the pins 120, and the tail end of the conductor layer extends to the outside of the tail end of the insulating layer and forms another pin 120.

[0052] In the above structure, the head end of the wire layer is extended to the outside of the head end of the insulating layer to form one of the pins 120, and the tail end of the wire layer is extended to the outside of the tail end of the insulating layer to form another pin 120, that is, the wire layer is exposed at both ends of the electrical conductor 110 to form the pin 120, thereby facilitating the processing and production of the pin 120.

[0053] In some embodiments, the electrical conductor 110 is specifically an enameled wire.

[0054] In the above structure, the electric conductor 110 is made of enameled wire, which is a copper wire with an insulating film. Due to the presence of the insulating film, the enameled wire is not easily damaged by mechanical or physical means, and can also avoid the influence of adverse environments on the coil, thereby being able to well protect the coil body 100. At the same time, the diameter of the enameled wire is thinner than that of ordinary copper wire, so a smaller coil can be made, which is also easier to match and use.

[0055] It can be understood that, in some embodiments, the electrical conductor 110 may specifically include at least one strand of enameled wire.

[0056] It is understandable that, in addition to the enameled wire, the electrical conductor 110 may also adopt other structures, such as a wrapped wire, an inorganic insulated wire, etc., and the present invention does not make any specific limitation on this.

[0057] An embodiment of the present invention further provides an inductor element, which includes the coil of any one of the above embodiments.

[0058] In the above structure, by setting the coil of any of the above embodiments, the coil includes a coil body 100, the coil body 100 is columnar, and the coil body 100 is formed by winding the electric wire 110 layer by layer from the inside to the outside, and the number of layers of the coil body 100 is 2N, N is an integer and N≥1; that is, during production, the electric wire 110 is wound layer by layer in an even number of layers from the inside to the outside to form the coil body 100, thereby enabling the two pins 120 of the coil body 100 to be located at the same end of the coil body 100, thereby reducing the height difference between the two pins 120, and making the subsequent power connection operation of the two pins 120 simpler and more convenient, thereby facilitating the power connection of the inductor element, and reducing the risk of damage to the pins 120 due to excessive height difference caused by the two pins 120 being located at the two ends of the coil body 100, thereby causing the subsequent power connection operation to be too complicated.

[0059] In some embodiments, the inductor element further includes an iron core, and the coil body 100 is located at the periphery of the iron core.

[0060] In the above structure, the coil body 100 is arranged on the periphery of the iron core, that is, the electric conductor 110 of the coil body 100 is wound around the periphery of the iron core. By adding an iron core to the coil, the strength and stability of the electromagnetic field can be enhanced, and the efficiency and performance of the coil can be improved. Specifically, the iron core can concentrate the magnetic field inside the coil inside the iron core through its magnetic conductivity, thereby enhancing the strength of the magnetic field, thereby increasing the inductance value, reducing the heat loss of the current, and also reducing problems such as leakage magnetic field and electromagnetic interference. In addition, the iron core can also help the coil generate a stronger induced potential and magnetic induction intensity, further improving the efficiency and application range of the inductor.

[0061] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
