DETAILED DESCRIPTION

[0034] Example implementations will now be described more fully with reference to the accompanying drawings.

Like reference numerals refer to like elements throughout the figures, and descriptions of the same elements will be omitted from descriptions of subsequent figures.

[0035] The words expressing position and direction described in the present application are explained by taking the drawings as an example, but changes can also be made as needed, and the changes made are included in the protection scope of the present application.

[0036] The present application relates to Figures 1 to 6 As shown in the figure, the present application discloses an integrated inductor, which comprises a protective cover 1, an inductor body 2 and two terminals 3.

[0037] The protective cover 1 is a relatively flat circular segment structure, and a cavity is arranged in the inside of the protective cover 1 for accommodating the inductor body 2, and a first limiting and fixing feature 11 (see Figure 1 and Figure 3 ) is arranged on the outside of the protective cover 1 for limiting and fixing the terminals 3.

[0038] In the present application, the protective cover 1 is preferably made of plastic material by injection molding, which has low cost and can effectively prevent the inductor body 2 from electric leakage and avoid the risk of electric shock. The first limiting and fixing feature 11 can be two square holes 111 arranged side by side, and a necked structure is arranged at the hole opening of the square hole 111 (see Figure 6), so as to accurately limit the terminal 3 in the X-axis and Y-axis directions, guarantee the precision and reliability of the connection between the terminal 3 and the target main board (i.e. the main circuit board), and at the same time, make the terminal 3 have a certain floating space in the Z-axis direction, thereby solving the problem of the installation gap of the inductor by absorbing the dimensional error.

[0039] The inductor body 2 is arranged in the protective cover 1, and the two are quickly fixed by glue dispensing, and the inductor body 2 is provided with input and output lines 21, 22 for connecting two terminals 3 (see Figure 5 ).

[0040] The terminal 3 is in an L-shaped structure and has two numbers. One end of each of the two terminals 3 is connected with the input and output lines 21, 22 respectively, so as to realize the conductive connection between the inductor body 2 and the terminal 3, and the other end of each of the two terminals 3 is arranged in the first limiting and fixing feature 11 after being bent, so that the terminal 3 is limited and fixed on the protective cover 1 and can float up and down in the Z-axis direction, thereby absorbing the dimensional error and facilitating the locking and fixing between the terminal 3 and the target main board.

[0041] In addition, each terminal 3 is further provided with a nut 4 for conductive connection with the target main board. Specifically, the nut 4 can be connected with a conductive through hole on the target main board through a screw (not shown), so as to realize the conductive connection between the terminal 3 and the target main board.

[0042] In the present application, the terminal 3 is preferably made of copper stamping, which is convenient to process and has good conductivity. As shown in Figure 5 The terminal 3 includes a connecting segment 31 and a bent segment 32 connected perpendicularly thereto. The connecting segment 31 of each terminal 3 is provided with a butt joint hole 311 for welding and fixing with the input and output lines 21, 22 respectively. The bent segment 32 of each terminal 3 is in a T-shaped structure, which cooperates with the square hole 111 and the necked structure at the hole opening to effectively limit the terminal 3 from being separated from the protective cover 1, but does not affect the floating of the terminal 3 up and down in the Z-axis direction.

[0043] In summary, the integrated inductor can avoid the steps of welding the soft cable and heat-shrinking the plastic protective sleeve by welding the input and output lines 21, 22 of the terminal 3 and the inductor body 2, thereby effectively reducing the material cost and the process, saving the size space, avoiding the problems of increasing the cable fixing structure and wire arrangement when the inductor body 2 uses the welded cable, effectively reducing the operation difficulty and improving the production efficiency. In addition, the terminal 3 has a certain floating ability in the Z-axis direction, so as to guarantee that the terminal 3 can absorb the dimensional error when being locked and fixed with the target main board, thereby improving the applicability and reliability.

Among them, the screw fixing hole 121 is arranged on the outer side of the first limiting and fixing feature 11, and the shield 1 is fixed with the box body (not shown) by screw locking. The positioning rib 122 is a clamping structure, and there are two of them, which are symmetrically arranged on both sides of the screw fixing hole 121, and are used to cooperate with the first pair of handles (not shown) on the upper end of the box body, so as to limit the top area of the shield 1. The positioning hole 123 has two, which are arranged side by side in the vault area (the bottom area shown in the figure) of the shield 1, and are used to cooperate with the second pair of handles (not shown) on the upper end of the box body, so as to limit the bottom area of the shield 1, thereby ensuring the accuracy of the installation position of the shield 1.

[0046] Referring to Figure 3 and Figure 5 As shown, in some embodiments, the nut 4 is riveted at the inner corner of the terminal 3 and located outside the edge of the inductor body 2. This design makes full use of the circular feature of the inductor body 2, minimizes the distance between the nut 4 and the center of the inductor body 2 in the Z-axis direction on the basis of ensuring the electrical clearance, and ensures the comprehensive minimization of the size of the inductor in the Y-axis and Z-axis directions.
