Description

Technical Field

[0001] The utility model relates to the technical field of magnetic integrated inductors, in particular to a regulating device. Background Art

[0002] By winding multiple inductor coils around a pair of magnetic cores, magnetic integrated inductors can reduce the size and weight of magnetic components. They also reduce current ripple, lower magnetic component losses, and improve the dynamic performance of power supplies, significantly enhancing power supply performance and power density. Specifically, the magnetic integrated inductor comprises an upper cover, a lower cover, and several columns secured between the upper and lower covers. The coils are spaced apart and mounted on these columns.

[0003] For magnetic integrated inductors consisting of only one center column and two side columns, the traditional assembly process involves gluing the lower cover, center column, and side columns together and then placing them into a jig cavity for fixation. The jig, along with the lower cover, center column, and side columns within it, is then baked and removed after the glue is dried. The jig is removed, a coil is placed on the two side columns, and the upper cover is glued in place. The inductance of the magnetic integrated inductor is adjusted by manually squeezing the gaps between the upper, lower, center, and side columns. Once adjusted, the inductor is secured between the upper and lower covers with steel tie wraps. The inductor is then baked again and removed after the glue is dried. However, manually squeezing the gaps between the upper, lower, center, and side columns to adjust the inductance of the magnetic integrated inductor results in unstable values, which can compromise product quality.

This can shorten operation time, improve work efficiency, and reduce costs.

[0062] like Figure 6As shown, the assembly process of the magnetic integrated inductor 1 in this embodiment is: place the steel tie in the groove 72 of the fixing member 7, glue the second cover plate 12 and the second column 15, and then put them into the accommodating cavity 71 above the groove 72 for fixation; glue the first column 13 to the second cover plate 12, set the coil 14 on the two first columns 13, and then glue the first cover plate 11; manually squeeze the gap between the first cover plate 11, the second cover plate 12, the two first columns 13 and the second column 15 to preliminarily adjust the inductance; after the adjustment is completed, tie the steel tie between the first cover plate 11 and the second cover plate 12 for fixation; remove the fixing member 7, place the magnetic integrated inductor 1 in the placement space of the adjustment device, and adjust the inductance again; remove the adjustment device, bake the magnetic integrated inductor 1, and take it out after the glue is dried. By placing the steel cable tie in the groove 72 of the fixing member 7 and then placing the second cover plate 12 and the second column 15 into the accommodating cavity 71, the magnetic integrated inductor 1 can be fixed in the accommodating cavity 71, and the structure is not easily misaligned; by placing the magnetic integrated inductor 1 in the placement space of the adjustment device, the inductance can be adjusted more precisely, and the result is more accurate.
