Description

Technical Field

[0002] UU common-mode inductor is a dual-coil inductor component. The two coils are wound in parallel on the skeleton and fastened together with two mirror magnetic cores. UU common-mode inductor is usually used in power supply filtering, EMI filtering and other applications, and can effectively suppress common-mode noise signals.

[0003] The installation process of UU-type common-mode chokes is relatively inconvenient and may lead to an increased failure rate. In addition, if the inductance requirement is large, the wires may be squeezed together, thus affecting safety. Utility Model Content

[0004] In order to solve the problems in the related art, the utility model provides a UU-type common-mode magnetic powder core inductor, which solves the problem of inconvenient assembly of the UU-type common-mode inductor.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] The utility model provides a UU-shaped common-mode magnetic powder core inductor, comprising a horizontally arranged square base, a magnetic core and a coil being arranged on the base, two magnetic cores being provided, the two magnetic cores being arranged opposite to each other, the two magnetic cores being arranged parallel and side by side along the width direction of the base, two horizontally arranged magnetic core columns being provided between the two magnetic cores, the magnetic core columns being perpendicular to the magnetic core, both ends of the magnetic core columns being against the inner wall of the magnetic core, the magnetic core columns being fixedly connected to the magnetic core, and coils being wound around the magnetic core columns.

[0007] The above scheme has a simple structure and is easy to assemble by setting up the magnetic core, coil and base. It only needs to wrap the wire around the magnetic core column to form a coil, and then install the magnetic core on the base to complete the assembly, thereby solving the problem of inconvenient assembly of UU-type common-mode inductors and realizing automated production, so that the produced inductors have good consistency. At the same time, it has good EMC compatibility and improves the inductor impedance characteristics.

[0008] Both ends of the base are provided with vertical support plates, the bottom of the support plate is fixedly connected to the base, and the top of the support plate is provided with a recess adapted to the bottom of the magnetic core.

[0009] In the above solution, the support plate is provided to place the magnetic core, which facilitates accurate positioning and enables rapid installation of the structure.

[0010] The coil is a single flat wire, which is wound from one magnetic core column to another magnetic core column to form the coil.

[0011] A gap is provided between the two coils.

[0012] In the above scheme, the two coils are arranged so as not to contact each other, and a gap is formed, so that air or other cooling medium can flow quickly through the gap, effectively taking away the heat generated by the coils during operation, thereby achieving the purpose of rapid heat dissipation.

[0013] The magnetic core is formed in one go by die-casting.

[0014] In the above solution, the magnetic core is die-cast in one step to improve the stability and reliability of the structure.

[0015] The base is provided with a plurality of through holes for passing the coil wire ends.

Two horizontally arranged magnetic core columns are provided between the two magnetic cores. The magnetic core columns are perpendicular to the magnetic core, both ends of the magnetic core columns are against the inner wall of the magnetic core, and the magnetic core columns are fixedly connected to the magnetic core. Coils are wound on the magnetic core columns. Through the arrangement of the magnetic core, coil and base, the structure is simple and the assembly is convenient. It is only necessary to wind the wire around the magnetic core column to form a coil, and then install the magnetic core on the base to complete the assembly. The assembly is convenient and automatic production is realized, so that the produced inductor has good consistency. At the same time, the EMC compatibility effect is good and the inductor impedance characteristics are improved.

[0018] 2. Both ends of the base are provided with vertical support plates for placing the magnetic core, which is convenient for precise positioning and rapid installation of the structure. The coil is a single flat wire, which is wound from one magnetic core column to another magnetic core column to form the coil. The two coils do not contact each other, forming a gap, so that air or other cooling media can flow quickly through the gap, effectively taking away the heat generated by the coil when it is working, thereby achieving the purpose of rapid heat dissipation. The magnetic core is formed in one go by die-casting to improve the stability and reliability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS
