[0018] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0019] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0021] The embodiment of the utility model provides a novel vertical inductor, such as Figure 1 and Figure 2 As shown, it includes an inductor body 100, a coil 200 and two electrode sheets 300. The inductor body 100 is pressed from magnetic powder, and can be specifically formed by hot pressing. The coil 200 is buried in the inductor body 100. When pressing the inductor body 100, the coil 200 is buried in the magnetic powder. After hot pressing through a mold, the coil 200 is formed integrally with the inductor body 100. The coil 200 is wound from a single wire body, and the single wire body can be made of copper wire. The two electrode sheets 300 are respectively connected to the two ends of the wire body as a whole, and the two electrode sheets 300 are pressed from the wire body. Since the wire body is thicker, the end of the wire body can be flattened into a sheet structure to form the electrode sheet 300. The axial direction of the coil 200 is perpendicular to the front side of the inductor body 100 to reduce the area of ​​the bottom surface of the inductor body 100. The two electrode sheets 300 each include a lead-out portion 310 connected to the wire body. The lead-out portion 310 is parallel to the axial direction of the coil 200, that is, the lead-out portion 310 is parallel to the bottom surface of the inductor body 100, thereby facilitating the bending of the electrode sheet 300. The lead-out portions 310 of the two electrode sheets 300 extend from the left side and the right side of the inductor body 100 respectively to enable the coil 200 to be energized and work.

[0022] The coil 200 of the present embodiment is wound by a single wire, and the two electrode sheets 300 are respectively connected to the two ends of the wire in one piece, and the two electrode sheets 300 are both pressed by the wire. The integrally connected structure can strengthen the connection strength between the coil 200 and the electrode sheets 300, so that the electrode sheets 300 are not easily separated from the coil 200, and the connection between the two is more firm; at the same time, the manufacturing process can be simplified, and the coil 200 and the electrode sheets 300 are conveniently formed in one piece.

[0023] In some embodiments, the portions of the wire body connected to the two electrode plates 300 at both ends are coaxially arranged with each other, that is, the portion of the wire body connected to one of the electrode plates 300 at one end and the portion of the wire body connected to the other electrode plate 300 at the other end are coaxially arranged with each other. Such an arrangement enables the two electrode plates 300 to be symmetrically distributed with respect to the vertical plane where the central axis of the coil 200 is located, facilitating welding.

[0024] Further, the wire body includes a straight tube portion 210, a spiral portion 220, and a bending portion 230. The straight tube portion 210 is in a straight tube shape, the spiral portion 220 is spirally wound, and the axial direction of the spiral portion 220 is perpendicular to the front side of the inductor body 100. One end of the straight tube portion 210 is connected to one end of the spiral portion 220, and the other end of the straight tube portion 210 is connected to one of the electrode plates 300. One end of the bending portion 230 is connected to the other end of the spiral portion 220, the other end of the bending portion 230 is bent below the spiral portion 220 and connected to the other electrode plate 300, and the portion of the bending portion 230 connected to the electrode plate 300 is coaxially arranged with the straight tube portion 210, that is Figure 2 the cylindrical portion 231 in

[0025] Since the wire body in this embodiment is relatively thick, when it is spirally wound, the two ends of the wire body are at different positions in the axial direction of the coil 200, so that the electrode plates 300 connected to the ends of the wire body cannot be symmetrically distributed. For this reason, the bending portion 230 in this embodiment is bent below the spiral portion 220, which is equivalent to one end of the wire body winding from below the spiral portion 220 to the other end of the spiral portion 220, so as to realize that the portions of the two ends of the wire body connected to the two electrode plates 300 are coaxially arranged with each other.

[0026] In some embodiments, both of the two electrode plates 300 further include a connecting portion 320 and a welding portion 330. The end of the wire body, the lead-out portion 310, the connecting portion 320, and the welding portion 330 are connected in sequence. The connecting portions 320 of the two electrode plates 300 are respectively located on the left side surface and the right side surface of the inductor body 100, and the welding portions 330 of the two electrode plates 300 are both located on the bottom surface of the inductor body 100. The welding portion 330 is used for welding to fix the entire inductor to the circuit board. Among them, the connecting portion 310 and the lead-out portion 320 can be perpendicularly connected, and the lead-out portion 320 and the welding portion 330 can also be perpendicularly connected. The cross-sectional shape of the entire electrode plate 300 is formed like a "U" shape. The connecting portion 310, the lead-out portion 320, and the welding portion 330 can be formed by bending a single electrode plate, which is convenient for integral manufacturing and forming.

[0027] Furthermore, the left and right sides of the inductor body 100 are both provided with slots 110, the slots 110 penetrate the inductor body 100 along the axial direction of the coil 200, and the connection parts 320 of the two electrode sheets 300 are respectively located in the two slots 110. This makes the lead-out part 320 not protrude from the side of the inductor body 100, and the side of the inductor body 100 is relatively flatter, and it is not easy to interfere with adjacent components on the circuit board. At the same time, since the slots 110 penetrate the inductor body 100 along the axial direction of the coil 200, relatively speaking, the number of inner wall surfaces of the slots 110 can be reduced, which is convenient for demoulding.

[0028] Furthermore, bottom grooves 120 are provided on the left and right sides of the bottom surface of the inductor body 100, and the two bottom grooves 120 are respectively connected to the two slots 110, so that the bent welding portion 330 can directly enter the bottom groove 120. The bottom groove 120 penetrates the inductor body 100 along the axial direction of the coil 200, and the welding portions 330 of the two electrode sheets 300 are respectively located in the two bottom grooves 120. The bottom groove 120 can contain tin liquid, which is convenient for tinning and fixing the inductor. At the same time, since the slots 110 and the bottom groove 120 both penetrate the inductor body 100 along the axial direction of the coil 200, and the bottom groove 120 is connected to the slots 110, notches are formed on both sides of the bottom of the inductor body 100, further reducing the area of ​​the bottom surface of the inductor body 100.
