Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a flat wire vertical winding reactor with current detection. Background Art

[0002] At present, most traditional reactors are E-shaped magnetic cores or mouth-shaped magnetic cores, and copper flat wires are wound around the E-shaped magnetic cores or mouth-shaped magnetic cores. To ensure the convenience of winding, the wide surface of the traditional copper flat wire is in close contact with the magnetic core. At the same time, to prevent short circuits between turns, an insulating material is wrapped outside the copper flat wire. However, through long-term practical experience, it is found that usually for the convenience of installation, the existing flat wires are generally vertically wound in advance, and then the vertically wound flat wires are integrally placed on the E-shaped or mouth-shaped magnetic cores. This installation method will result in poor fit between the flat wires and the magnetic cores, thus affecting the product quality. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a flat wire vertical winding reactor with current detection, which solves the problem of unstable connection between the flat wire and the magnetic core.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A flat wire vertical winding reactor with current detection includes a yoke and a magnetic column unit. The yoke includes a first yoke part and a second yoke part. There is at least one magnetic column unit between the first yoke part and the second yoke part. The magnetic column unit has two core columns. After the two core columns are assembled, they are used to install the coil and are in sliding contact connection between the two core columns. One core column is connected to the first yoke part, and the other core column is connected to the second yoke part.

[0006] By adopting the above technical solution: The magnetic column is formed by splicing two core columns. By adjusting the relative position between the two core columns, the coil can better fit with the magnetic core, reduce the air gap between the coil and the magnetic core, improve stability, and ensure product quality.

[0007] The core column has a winding part and a positioning part. One end of the winding part on one core column is in sliding connection with the end face of the positioning part on the other core column. The end face of the positioning part on the core column away from the winding part is connected to the corresponding yoke part.

[0008] By adopting the above technical solution: The winding part of the core column is used to install the coil, and the positioning part of the core column is used to connect with the yoke. By changing the shape of the first yoke part or the second yoke part, an E-shaped magnetic core structure can be obtained. In addition, there is a mouth-shaped cavity left between the first core column and the second core column after assembly for heat dissipation.

[0009] The core column is of an L-shaped structure. Its shorter extension arm is the winding part, and the other extension arm is the positioning part. Guide ribs are provided on the inner end face of the positioning part, and a guide groove connected to the corresponding guide ribs is provided at one end of the winding part.

[0010] By adopting the above technical solutions: The core column with an L-shaped structure can well assemble the magnetic columns. The positioning part of the core column is provided with guiding ribs, and the winding part is provided with guiding grooves that cooperate with the guiding ribs. The two core columns are fitted according to the guiding grooves and guiding ribs to ensure stability. When the positions between the two core columns are determined, the positioning part of the core column is connected to the yoke part to further ensure the overall stability of the magnetic core.

[0011] Two groups of the magnetic column units are provided, and the two magnetic column units are symmetrically arranged at the edges of the magnetic yoke, and the winding parts of the two magnetic column units are arranged in parallel.

[0012] By adopting the above technical solutions: Two magnetic column units are arranged on the magnetic yoke, and a square-shaped magnetic core can be assembled. The winding parts of the two magnetic columns are arranged in parallel to ensure the rationality of the flat wire wound vertically on the square-shaped magnetic core, and further ensure the product quality of the square-shaped magnetic core assembled by the magnetic yoke and the magnetic column units.

[0013] Positioning holes are formed on both the first yoke part and the second yoke part, and bolt holes corresponding to the respective positioning holes are formed on the positioning part of the core column.

[0014] By adopting the above technical solutions: When the position of the winding part in the magnetic column unit is determined, the magnetic column unit can be fixed by connecting the positioning part of the magnetic column unit to the yoke part. Specifically, bolt holes are formed on the positioning part, and the overall installation of the magnetic core can be realized through the connection between the bolt holes on the positioning part and the corresponding positioning holes.

[0015] Insulating pads are provided between the magnetic column unit and the first yoke part and the second yoke part, and relief holes corresponding to the positioning holes are formed on the insulating pads.

[0016] By adopting the above technical solutions: The insulating pads are provided to separate the coil from the magnetic yoke to ensure the product quality.

Detailed implementation manners

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0027] This solution provides a flat wire vertical-wound reactor with current detection, which includes a magnetic yoke 1 and a magnetic column unit 2. The magnetic yoke 1 includes a first yoke part 101 and a second yoke part 102. There is at least one magnetic column unit 2 between the first yoke part 101 and the second yoke part 102. The magnetic column unit 2 has two core columns. After the two core columns are assembled, they are used to install the coil and are in sliding contact connection with each other. One core column is connected to the first yoke part, and the other core column is connected to the second yoke part. The magnetic column in this solution is formed by splicing two core columns. By adjusting the relative position between the two core columns, the coil can better fit the magnetic core to ensure the product quality. In addition, an "O"-shaped cavity is left between the first core column 201 and the second core column 202 after assembly for heat dissipation.

[0028] Furthermore, the winding part of the core column is used to install the coil, and the positioning part of the core column is used to connect with the yoke 1. Each core column has a winding part and a positioning part. By changing the shape of the first yoke part 101 or the second yoke part 102, an E-shaped magnetic core can be obtained. And when two core columns are combined, one end of the winding part on one core column is slidably connected to the end face of the positioning part on the other core column, and the end face of the positioning part on the core column far from the winding part is connected to the corresponding yoke part.

[0029] Embodiment 1

[0030] As Figure 1 shown, in this embodiment, the core column adopts an L-shaped plate structure, and its shorter extension arm is used as the winding part, and the other extension arm is used as the positioning part. As Figure 2 shown, guide ribs are provided on the inner end face of the positioning part, and a guide groove connected to the corresponding guide rib is provided at one end of the winding part. In this embodiment, a first guide rib 2011 is provided on the positioning part of the first core column 201, a second guide groove connected to the first guide rib 2011 is provided at one end of the winding part of the second core column 202, a second guide rib 2021 is provided on the positioning part of the second core column 202, and a first guide groove connected to the second guide rib 2021 is provided at one end of the winding part of the first core column 201. Then, the guide ribs and the guide grooves can be connected in pairs to facilitate the rapid assembly of the magnetic core. Therefore, the core column with an L-shaped structure in this embodiment can be well assembled for the magnetic column. By providing guide ribs on the positioning part of the core column and guide grooves on the winding part that cooperate with the guide ribs, the two core columns are matched according to the guide grooves and the guide ribs, that is, the I-shaped magnetic core as Figure 1 shown. Again, as Figure 4 shown, if the second yoke part 102 adopts a U-shaped structure, an E-shaped magnetic core can be assembled.

[0031] Furthermore, when the positions between the two core columns are determined, the positioning parts of the core columns are connected to the yoke parts. For specific illustration, reference can be made to Figure 1 , the positioning part of the first core column 201 is connected to the first yoke part 101, and the positioning part of the second core column 202 is connected to the second yoke part 102, further ensuring the overall stability of the magnetic core.

[0032] Embodiment 2

[0033] As Figure 5 shown, the difference between this embodiment and Embodiment 1 is that there are two sets of magnetic column units 2, and the two magnetic column units 2 are symmetrically arranged on the edge of the yoke 1, and the winding parts of the two magnetic column units 2 are arranged in parallel. Then, an O-shaped magnetic core can be assembled. By arranging the winding parts of the two magnetic columns in parallel, the rationality of the flat wire wound vertically on the O-shaped magnetic core is ensured, and further the product quality of the O-shaped magnetic core assembled by the yoke 1 and the magnetic column unit 2 is ensured.

[0034] It should be added that, Figure 3 As shown, positioning holes 103 are provided on both the first yoke 101 and the second yoke 102, and bolt holes 203 corresponding to the corresponding positioning holes 103 are provided on the positioning portion of the core column. After the winding portion in the magnetic column unit 2 is positioned, the magnetic column unit 2 can be fixed by connecting the positioning portion of the magnetic column unit 2 with the yoke. Specifically, bolt holes 203 are provided on the positioning portion, and the entire magnetic core can be installed by connecting the bolt holes 203 on the positioning portion with the corresponding positioning holes 103. In addition, in the above-mentioned embodiments 1 and 2, insulating pads 3 are provided between the magnetic column unit 2 and the first yoke 101 and the second yoke 102. The insulating pads 3 are provided with clearance holes corresponding to the positioning holes 103. By providing the insulating pads 3 to separate the coil and the magnetic yoke 1, the product quality can be guaranteed.

[0035] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
