Description

Technical Field

[0001] This invention relates to the field of combined inductor technology, specifically to a semi-encapsulated combined inductor. Background Technology

[0002] A composite inductor is composed of two or more inductor coils. By connecting them together, the desired inductance value can be obtained. It is mainly used in various circuits and applications, greatly improving the flexibility and adjustability of the circuit. A composite inductor mainly consists of three parts: a coil, a magnetic core, and a housing. Depending on the type of magnetic core, it can be divided into ferrite, alloy, and ceramic types. Ferrite has high permeability but a narrow frequency range; alloys have high permeability and wide bandwidth characteristics; ceramics have advantages such as high frequency, wide bandwidth, and small size. Referring to Chinese patent publication number "CN116564650A" entitled "A Semi-Encapsulated Composite Inductor," the existing composite inductors in this patent suffer from problems such as large size, low efficiency, high cost, poor heat dissipation, and poor EMI filtering effect. Furthermore, this device still has problems with poor heat dissipation and inconvenient installation. Therefore, we propose a semi-encapsulated composite inductor to solve the above problems. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a semi-encapsulated composite inductor, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a semi-encapsulated combined inductor, comprising a rectangular outer shell, magnetic core bodies provided on both sides of the inner side of the rectangular outer shell, a positioning base fixedly installed at the bottom of the magnetic core body, and an enameled wire body wound inside the magnetic core body.

[0005] Multiple lead wire bodies are fixedly installed at the bottom of the rectangular outer shell, and the multiple lead wire bodies are respectively connected to the corresponding magnetic core body. The inside of the rectangular outer shell is filled with potting compound.

[0006] The rectangular outer casing contains multiple heat dissipation conduits, all of the same shape and arc-shaped. These conduits are positioned on opposite sides of the corresponding magnetic core body, and their ends penetrate the rectangular outer casing. All conduits are hollow, designed to conduct heat generated during device operation.

[0007] A heat dissipation plate frame is fixedly installed below the positioning base. The heat dissipation plate frame penetrates the bottom of the rectangular outer shell, and a sealing ring frame is fixedly installed on the outer side of the heat dissipation plate frame. The sealing ring frame fits against the inner bottom of the rectangular outer shell. Multiple rectangular slots are symmetrically opened inside the heat dissipation plate frame, and heat dissipation fins are fixedly installed inside each rectangular slot.

[0008] Preferably, the plurality of heat dissipation conduits are respectively attached to the corresponding enameled wire body, and a distance is left between the installation position of the heat dissipation conduit and the inner wall of the rectangular outer shell.

[0009] Preferably, a distance is left between the magnetic core bodies on both sides of the rectangular outer shell for potting and filling adhesive, and a limiting partition is provided between the two magnetic core bodies to block the magnetic core bodies on both sides.

[0010] Preferably, a bottom positioning frame is fixedly installed in the middle of the inner side of the rectangular outer shell, the limiting partition is slidably installed inside the bottom positioning frame, and a plurality of spring bodies are fixedly installed between the limiting partition and the inside of the bottom positioning frame.

[0011] Preferably, a plurality of rubber support columns are fixedly installed inside the rectangular outer shell, and the positioning base is placed on top of the corresponding rubber support columns.

[0012] Preferably, both sides of the rectangular outer shell are provided with assembly components, which can be used to assemble the rectangular outer shell into a preset position.

[0013] Preferably, the assembly assembly includes a positioning plate frame and a mounting plate. The mounting plate is fixedly installed on the outer middle of the rectangular outer shell. The positioning plate frame is slidably connected to the corresponding mounting plate. Multiple support springs are fixedly installed between the positioning plate frame and the corresponding mounting plate. Multiple assembly brackets are slidably installed on the outer side of the positioning plate frame.

[0014] Preferably, by cooperating with the mounting frame and the positioning plate frame, the mounting frame can be adjusted to the appropriate position when installing the rectangular outer shell, and then the mounting frame can be locked to the preset position by bolts to complete the assembly operation of the rectangular outer shell. Compared with the traditional installation method, this can improve the installation convenience and applicability of the equipment.

[0015] Preferably, the positioning plate frame has symmetrically provided limit grooves on both the upper and lower sides, and the outer side of the assembly frame is fixedly installed with a slider that matches the limit groove.

[0016] Preferably, multiple protective pads are fixedly installed on the outer side of the mounting plate, and elastic protective plates are fixedly installed between the positioning plate frame and the end of the mounting plate.

[0017] Preferably, assembly holes are symmetrically provided on both sides of the interior of the plurality of assembly racks.

[0018] Preferably, the slider is slidably installed inside the limiting groove, which facilitates the adjustment of the assembly frame position. At the same time, when the assembly frame is installed by inserting the positioning bolt into the assembly hole, the slider and the limiting groove can be subjected to relative force, thus preventing the rectangular outer shell from sliding after installation.

Compared with the traditional installation method, it can effectively improve the installation convenience and applicability of the equipment. Attached Figure Description
