Technical Field
[0001] This utility model relates to the field of reactor technology, specifically to a high-power flat wire inductor that is wound in a fully automated manner. Background Technology
[0002] Flat wire inductors are inductors that use flat copper wire as a conductor. Because of their flat cross-section, these wires can better adapt to a variety of compact installation environments. Their structure includes a coil section and a lead section. Currently, there are many types of fully automated winding high-power flat wire inductors available on the market, but they still have some drawbacks.
[0003] For example, Chinese utility model patent CN222168112U discloses a high-power flat wire vertically wound hollow inductor, in which the coil assembly adopts multi-strand hollow wire spiral three-dimensional winding. The use of multi-strand hollow wire can increase the effective heat dissipation area of the coil, while reducing the volume and weight of the reactor. The multi-strand vertical winding of the coil can effectively reduce the proximity effect and improve the electrical performance of the product. The coil is directly fixed by the coil insulation fixing frame, which improves manufacturing and use efficiency; it is suitable for fully automated equipment operation.
[0004] The existing technologies mentioned above have the following technical problems: gaps are generated during the automated winding of flat wires, which reduces the compactness of the windings and makes it impossible to quickly install the coil assembly with the insulating shell, indicating a design deficiency. In addition, the flat wire inductor has a connecting pin on the outside. If the connecting pin is not protected during transportation, it will be damaged. Therefore, we propose a fully automated high-power flat wire inductor to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this invention is to provide a fully automated high-power flat wire inductor to solve the problems mentioned in the background art. Currently, when using fully automated flat wire inductors, gaps are generated between the wires during the automated winding process, which reduces the compactness of the winding and makes it impossible to quickly install the coil assembly with the insulating shell. The design has shortcomings. In addition, the flat wire inductor has a connecting pin on the outside. If the connecting pin is not protected during transportation, it will be damaged.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-power flat wire inductor with fully automated winding, comprising:
[0007] An upper insulating shell is provided below the upper insulating shell, and a bracket is provided between the upper and lower insulating shells. The upper and lower sides of the bracket are engaged with slots, which are located inside the upper and lower insulating shells. A coil is wound around the outside of the bracket.
[0008] Also includes:
[0009] The bracket is symmetrically provided with clamping mechanisms on its outer left and right sides to increase the short-circuit resistance of the coil.

The clamping plate is fixedly connected to the inner side of the first spring, and the coil is tightly attached to the inner side of the clamping plate.
[0011] Preferably, the lower part of the upper insulating shell is symmetrically and equidistantly equipped with locking pins, and the lower part of the locking pins is engaged with locking holes, which are symmetrically and equidistantly located inside the lower insulating shell.
[0012] Preferably, fixing blocks are rotatably installed on the upper left and right sides of the lower insulating shell, and the fixing blocks are tightly fitted with the lower left and right sides of the upper insulating shell, and the fixing blocks are fixedly connected to the upper insulating shell by bolts.
[0013] Preferably, the upper insulating shell and the lower insulating shell are provided with protective covers on their front sides, and the upper and lower sides of the outer side of the protective covers are tightly fitted with limit strips.
[0014] Preferably, a second spring is fixedly connected to the rear side of the limiting strip.
[0015] Preferably, the upper and lower rear sides of the second spring are fixedly connected to the interior of the upper insulating shell and the lower insulating shell, respectively.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This fully automated high-power flat wire inductor, by setting a clamping mechanism, can ensure that the flat wire will greatly improve the compactness of the winding during the winding process, thereby increasing the short-circuit resistance. At the same time, it is set with an easy installation mechanism, which can quickly install the coil assembly and the insulating shell, improving the installation efficiency and facilitating disassembly. Furthermore, it is set with a protective mechanism, which can effectively protect the flat wire joints and ensure that the flat wire joints will not be damaged by collisions during transportation.

Since the second spring has elasticity, it is convenient to pull the limit strip and to disassemble the protective cover. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-6 This utility model provides a technical solution:
[0031] To address the problems existing in the prior art, this embodiment provides the following technical solution: a fully automated high-power flat wire inductor with an upper insulating shell 1; a clamping mechanism located on the left and right sides of the coil 3, which can clamp and limit the coil 3 during automated winding, thereby improving the compactness of the coil 3 winding; an easy-to-install mechanism located between the upper insulating shell 1 and the lower insulating shell 7, which facilitates quick installation and connection of the upper insulating shell 1 and the lower insulating shell 7 to the bracket 2, improving installation efficiency and facilitating disassembly; and a protective mechanism located on the front side of the upper insulating shell 1 and the lower insulating shell 7, which can effectively protect the connecting feet located on the front side of the coil 3.
[0032] like Figure 4 , Figure 5 and Figure 6As shown, the bracket 2 is connected by aligning the upper and lower sides of the bracket 2 with the slots 12 inside the upper insulating shell 1 and the lower insulating shell 7. At the same time, the upper insulating shell 1 is symmetrically provided with locking pins 8 on the lower left and right sides, and the lower insulating shell 7 is symmetrically provided with locking holes 9 on the inner left and right sides. The locking pins 8 and locking holes 9 will also be connected by locking. The fixing blocks 10 are installed by rotating the fixing blocks 10 on the outer left and right sides of the lower insulating shell 7. The fixing blocks 10 can be rotated upward and inward to fit against the outer side of the upper insulating shell 1. Then, the bolts 11 are inserted into the fixing blocks 10 and tightened inside the upper insulating shell 1. This strengthens the fixed connection between the upper insulating shell 1 and the lower insulating shell 7. At this time, the bracket 2 is firmly installed between the upper insulating shell 1 and the lower insulating shell 7.
[0033] Connecting brackets 4 are symmetrically installed on the left and right sides of the outside of bracket 2. First springs 5 are symmetrically installed on the left and right sides of the inner side of connecting brackets 4. The clamping plate 6 is fixedly connected to the inner side of the first spring 5. Since the first spring 5 has elasticity, it can push the clamping plate 6 to clamp the coil 3 during the winding process, which can greatly improve the compactness of the coil 3 winding. At the same time, the magnetic core shape is changed to EQ type, which can realize the automation of winding under high current. The flat wire is wound and then assembled with the magnetic core, which increases the production efficiency by more than 40% and the power density by more than 30%.
[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a protective cover 13 is provided on the front side of the upper insulating shell 1 and the lower insulating shell 7. The protective cover 13 can protect the connector installed on the front side of the coil 3. Since the upper and lower sides of the outer side of the protective cover 13 are tightly fitted with the limiting strip 14, and the rear side of the limiting strip 14 is fixedly connected to the second spring 15, the rear side of the second spring 15 is fixedly connected to the interior of the upper insulating shell 1 and the lower insulating shell 7 respectively. Since the second spring 15 is elastic, the limiting strip 14 can be pulled to separate it from the protective cover 13, so that the protective cover 13 can be taken out for easy connection of the connector.
[0035] The working principle of this fully automated high-power flat wire inductor is as follows: The upper insulating shell 1 and the lower insulating shell 7 can be quickly installed on the outside of the bracket 2, which can greatly improve the installation speed. At the same time, the coil 3 is set on the outside of the bracket 2, and the clamping plate 6 is symmetrically and tightly attached to the outside of the coil 3. Under the action of the first spring 5 set on the outside, the clamping plate 6 can press the coil 3, thereby improving the compactness of the coil 3 winding. Secondly, a protective cover 13 is set on the front side of the upper insulating shell 1 and the lower insulating shell 7. The protective cover 13 can effectively protect the connecting feet set on the front side of the coil 3.
