Description

Technical Field

[0001] The invention relates to the technical field of common mode filters, and in particular to a fast-assembly common mode filter. Background Art

[0002] The inventor of this case has previously proposed a Taiwan patent with publication number TWM569925U, a "quickly assembled inductor". The first figure of the case shows that a first coupling portion is provided on one side of the first flange of the first core, a second coupling portion is provided on one side of the second flange of the first core, a first coupled portion corresponding to the first coupling portion is provided on one side of the third flange of the second core, and a second coupled portion corresponding to the second coupling portion is provided on one side of the fourth flange of the second core, so that the first core and the second core are assembled and coupled in a concave-convex complementary manner through each coupled portion and each coupling portion.

[0003] However, the first core and the second core of the inductor are only connected by the connected parts and the connecting parts in a concave-convex complementary manner, and there is no connection between the inductor and the substrate. If it is not properly fixed, when the inductor is set on the substrate, the inductor may move or fall, which will affect the stability and reliability of the circuit. Or more seriously, there is no correct contact or connection point on the substrate, which may lead to poor contact between the inductor and the substrate, thereby causing circuit instability, signal attenuation, or even complete inability to work.

[0004] Therefore, how to eliminate the above-mentioned deficiencies is the technical difficulty that the inventor of this case wants to solve. Summary of the invention

[0005] The object of the present invention is to provide a fast-assembly common-mode filter to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: A quick-assembly common-mode filter comprises: a substrate; a plurality of plate bodies, the plurality of plate bodies comprising a middle partition and a plurality of partition plates, the middle partition being arranged at the center of the substrate, the plurality of partition plates being arranged at intervals or adjacent to the middle partition, and jointly surrounding a first accommodating area and a second accommodating area; and a plurality of inductors, the plurality of inductors being arranged in the first accommodating area and the second accommodating area respectively.

[0007] The plurality of partition plates include two first sub-partition plates, and the two first sub-partition plates are spaced relative to the middle partition plate, so that there is a distance between the middle partition plate and the two first sub-partition plates.

[0008] Among them, the multiple partition plates include two first sub-partition plates and two second sub-partition plates. The two first sub-partition plates are spaced relative to the middle partition plate so that there is a distance between the middle partition plate and the two first sub-partition plates respectively. The two second sub-partition plates are adjacent to the middle partition plate so that the two second sub-partition plates are adjacent to the middle partition plate respectively.

[0009] The plurality of partition plates include two second sub-partition plates, and the two second sub-partition plates are arranged adjacent to the middle partition plate, so that the two second sub-partition plates are adjacent to the middle partition plate respectively.

[0010] The substrate is provided with a shell, and the shell covers the plurality of inductors.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses the middle partition and the plurality of partition plates to jointly surround the first accommodating area and the second accommodating area to determine the correct positions of the plurality of inductors on the substrate, so that the plurality of inductors can be quickly and accurately positioned on the substrate during assembly to achieve optimal performance and manufacturing efficiency. Moreover, because they can be accurately positioned on the substrate, automated equipment operations are formed to achieve the purpose of convenience, speed, time saving and labor saving.
