[0023] like Figure 1 and Figure 2 As shown, this embodiment provides an inductor mounting structure, including: a housing 1 and an inductor pin transfer portion 2 .

[0024] The housing 1 has a cavity 10 for accommodating the inductor body 3 , and the cavity 10 is a slot-shaped structure with an open top. The housing 1 is used to accommodate and encapsulate the inductor body 3 .

[0025] The housing 1 includes a bottom plate 11 and a side wall 12 vertically surrounding the bottom plate 11 , wherein the side wall 12 is provided with a plurality of symmetrical inner recesses 13 .

[0028] Preferably, the inner recess 13 is formed by the side wall 12 being recessed toward the cavity 10 .

[0029] There are multiple inductor pin transfer parts 2 , which are staggered and symmetrically located at the top of the cavity 10 . The cavity 10 is divided into at least one sub-cavity by four adjacent inner recesses 13 .

[0030] Preferably, the size of each sub-cavity is consistent, that is, the space size of each sub-cavity is equal.

[0031] Each sub-cavity can accommodate a group of inductor bodies 3 , and a group of inductor bodies 3 needs to be connected to four inductor pin transfer parts 2 .

[0032] exist Figure 1 In the embodiment, the cavity 10 has only one sub-cavity, and the sub-cavity can accommodate a group of inductor bodies 3, and a group of inductor bodies 3 needs to be connected to four inductor pin transfer parts 2. Figure 2 In the embodiment, the cavity 10 has two sub-cavities, and six inner recesses 13 are symmetrically arranged on the side wall 12 , wherein four inner recesses 13 are located at four corners of the side wall 12 .

That is to say, the cavity 10 can accommodate two groups of inductor bodies 3, which need to be connected to eight inductor pin adapters 2.

[0034] It can be understood that when the number of the inner recesses 13 is eight, the cavity 10 has three sub-cavities, which can accommodate three groups of inductor bodies 3 and need to connect twelve inductor pin adapters 2. When the number of inductor bodies 3 changes, the same is true and will not be repeated.

[0035] The inner recess 13 is perpendicular to the bottom plate 11 so that the bottom plate 11 forms a mounting portion 14 ; the mounting portion 14 has a through hole 15 penetrating the bottom plate 11 , and the number of the mounting portions 14 is the same as the number of the inner recesses 13 .

[0036] Here, the mounting portion 14 is located outside the cavity 10, and the housing 1 can be fixed by using the through hole 15 on the mounting portion 14. For example, screws can be used for fixing.

[0037] The inductor pin adapter 2 is used to connect the pins 30 of the inductor body 3. As an example, the fixed connection can be performed by welding.

[0038] like Figure 4 and Figure 5 As shown, the inductor pin adapter 2 is a copper nose structure, including: a connecting portion 20, a rivet nut 21 and a fixing portion 22.

[0039] The fixing portion 22 is vertically arranged at one end of the connecting portion 20, and the other end of the connecting portion 20 is in an arc shape; the rivet nut 21 is vertically arranged on the connecting portion 20, and the rivet nut 21 and the fixing portion 22 are located on the same side of the connecting portion 20; the internal thread of the rivet nut 21 passes through the connecting portion 20.

[0040] The fixing portion 22 is connected to the inductor body 3. Preferably, the fixing portion 22 is a hollow embracing structure, and the fixing portion 22 is sleeved on the pin 30 of the inductor body 3.

[0041] Preferably, the connecting portion 20 is used to contact with an external copper busbar or a connecting wire harness, and the rivet nut 21 is used to cooperate with a screw that fixes the external copper busbar or the connecting wire harness.

[0042] This embodiment further provides an inductor, comprising: an inductor body 3 and the inductor mounting structure as described above.

[0043] Preferably, potting glue may be used to fix the inductor body 3 in the housing 1 of the inductor mounting structure.

[0044] During installation, the fixing portion 22 of each inductor pin adapter 2 is placed on the pin 30 of the inductor body 3, and the upper and lower assembly depths can be determined according to actual needs; after assembly, the fixing portion 22 and the pin 30 are welded and fixed; screws are used to cooperate with the through holes 15 on the mounting portion 14 to fix the inductor as a whole at the actual required position.
