[0038] Please refer to Figures 5 to 9 , Figure 5 It is a combination schematic view of the second embodiment of the vertical magnetic element 20 of the utility model. Figure 6 It is an exploded schematic view of the second embodiment of the vertical magnetic element 20 of the utility model. Figure 7 It is Figure 5 the exploded schematic view of another view. Figure 8 It is Figure 5 the top view schematic view. Figure 9 It is an exploded schematic view of the second embodiment of the vertical magnetic element 20 of the utility model. As Figure 5 shown, the vertical magnetic element 20 of the utility model comprises a main iron core body 21, the main iron core body 21 has a containing space S penetrating through it; a first vertical coil 22 and a second vertical coil 23 are respectively arranged in the containing space S. A first functional pad 24 is formed at one end of the first vertical coil 22 and perpendicular to the first vertical coil 22, and a second functional pad 25 is formed at one end of the second vertical coil 23 and perpendicular to the second vertical coil 23. The material of the main iron core body 21 can be, for example, but not limited to, ferrite or other soft magnetic materials. The main iron core body 21 can be a cube, a cuboid, a square, and the utility model is not limited to this. In order to facilitate assembly, the main iron core body 21 can be integrally formed, or two door-shaped or U-shaped iron core bodies can be combined. The containing space S penetrating through the main iron core body 21 can be I-shaped, cylindrical, square column, and the utility model is not limited.

[0039] Further supplementing the description, in Figure 5The first functional pad 24 and the second functional pad 25 are both exposed outside the main iron core body 21. Alternatively, the first functional pad 24 and the second functional pad 25 can both be not exposed outside the main iron core body 21.

[0040] In the second embodiment, the first vertical coil 22 and the second vertical coil 23 are parallel to each other. The first vertical coil 22 and the second vertical coil 23 can both be long columnar. Preferably, the appearance of the first vertical coil 22 and the appearance of the second vertical coil 23 are thick and thin in comparison. For example, the first vertical coil 22 can be a long columnar body thicker than the second vertical coil 23. In this way, the current passing through the first vertical coil 22 is greater than the current passing through the second vertical coil 23. It should be particularly pointed out that the present application does not limit the volume and thickness of the first vertical coil 22 and the second vertical coil 23. The first vertical coil 22 and the second vertical coil 23 can have the same volume and thickness, or can have different volume and thickness, depending on the actual application situation.

[0041] In the second embodiment, one end of the first vertical coil 22 is formed with the first functional pad 24, and the first functional pad 24 is perpendicular to the first vertical coil 22. One end of the second vertical coil 23 is formed with the second functional pad 25, and the second functional pad 25 is perpendicular to the second vertical coil 23. The setting of the first functional pad 24 and the second functional pad 25 can increase the surface area of signal contact.

[0042] Preferably, the first functional pad 24 and the second functional pad 25 extend towards the direction away from each other.

[0043] Please refer to Figure 6 and Figure 7 The first functional pad 24 has a first functional pad upper surface 24a and a first functional pad bottom 24b. The second functional pad 25 has a second functional pad upper surface 25a and a second functional pad bottom 25b. The first functional pad 24 can have a thickness, and the second functional pad 25 can have a thickness. The thickness of the first functional pad 24 can be greater than the thickness of the second functional pad 25, and the thickness of the second functional pad 25 can also be greater than the thickness of the first functional pad 24. It should be particularly pointed out that the present application does not limit the thickness of the first functional pad 24 and the second functional pad 25. The first functional pad 24 and the second functional pad 25 can also have the same thickness.

[0044] Preferably, the first functional pad bottom 24b and the second functional pad bottom 25b are arranged on the same horizontal plane.

[0045] Further, the other end of the first vertical coil 22 has a first vertical coil top surface 221, and the other end of the second vertical coil 23 has a second vertical coil top surface 231. When the first function pad 24 and the second function pad 25 are coupled to the circuit board, the first function pad 24 at one end of the first vertical coil 22 and the first vertical coil top surface 221 at the other end of the first vertical coil 22 can serve as input and output terminals of a signal (i.e., a signal can be transmitted from the first function pad 24 to the first vertical coil top surface 221 for output and / or a signal can be transmitted from the first vertical coil top surface 221 to the first function pad 24 for input), and the second function pad 25 at one end of the second vertical coil 23 and the second vertical coil top surface 231 at the other end of the second vertical coil 23 can serve as input and output terminals of a signal (i.e., a signal can be transmitted from the second function pad 25 to the second vertical coil top surface 231 for output and / or a signal can be transmitted from the second vertical coil top surface 231 to the second function pad 25 for input). The vertical path created by the first vertical coil 22 and the second vertical coil 23 reduces the additional route that a signal has to travel, directly transmits the signal in a straight line, reduces the signal transmission time, and increases the work efficiency.

[0046] Referring to Figure 8 , the first vertical coil 22 and the second vertical coil 23 have a gap ag1 therebetween, and the first vertical coil 22 and the second vertical coil 23 are insulated from each other. The gap ag1 can be air or any insulating material. Further, at least one of the first vertical coil 22 and the second vertical coil 23 does not contact the main core body 21. Specifically, the first vertical coil 22 and the second vertical coil 23 are insulated from the main core body 21, respectively. That is, the first vertical coil 22 and the second vertical coil 23 do not have any form of conduction with the main core body 21, respectively. Alternatively, in the case that the first vertical coil 22 and the second vertical coil 23 are insulated from each other and both the first vertical coil 22 and the second vertical coil 23 are insulated from the main core body 21, the first vertical coil 22 and the second vertical coil 23 can contact the main core body 21.

[0047] Referring to Figure 9 , Figure 9 A variation of the second embodiment of the vertical magnetic element is shown. In Figure 9The two ends of the vertical coil can be respectively provided with functional pads (i.e., the first functional pad 24 is arranged at one end of the first vertical coil 22, the first additional functional pad 26 is arranged at the other end of the first vertical coil 22, the second functional pad 25 is arranged at one end of the second vertical coil 23, and the second additional functional pad 27 is arranged at the other end of the second vertical coil 23). As known from the above, the number of vertical coils is not limited, and the number and arrangement of functional pads are not limited, and the functional pad can be arranged at any end of any vertical coil, or the functional pad can be arranged at both ends of each vertical coil, and the actual arrangement can be adjusted according to actual application requirements.

[0048] Similarly, when the first functional pad 24 and the second functional pad 25 are respectively plugged into the circuit board, the first functional pad 24 at one end of the first vertical coil 22 and the first additional functional pad 26 at the other end of the first vertical coil 22 can be used as the input end and the output end of the signal (i.e., the signal can be transmitted from the first functional pad 24 to the first additional functional pad 26 for output; the signal can be transmitted from the first additional functional pad 26 to the first functional pad 24 for input). The second functional pad 25 at one end of the second vertical coil 23 and the second additional functional pad 27 at the other end of the second vertical coil 23 can be used as the input end and the output end of the signal (i.e., the signal can be transmitted from the second functional pad 25 to the second additional functional pad 27 for output; the signal can be transmitted from the second additional functional pad 27 to the second functional pad 25 for input).

[0049] Further, the number of vertical coils of the vertical magnetic element can be one, two, three, four, or more than four, and the functional pad can be selectively arranged at both ends of each vertical coil. The shape of the functional pad is not limited, and can be square, circular, or polygonal.

[0050] Further, any functional pad of the second embodiment of the vertical magnetic element can be replaced with an L-shaped functional pad 14 as shown in FIG. 6. Figure 3 and Figure 4

[0051] Optionally, the vertical magnetic element 20 can be a transformer or a coupled inductor.
