Abstract
Description
Technical Field
[0001] This application relates to the field of transformer bobbin technology, and more particularly to a bobbin for reducing the difference in the number of winding layers between the primary and secondary windings. Background Technology
[0002] In the manufacturing process of transformers, the transformer frame is the component used for winding the coils. The transformer frame typically has a primary winding area and a secondary winding area. The primary winding serves as the input terminal, used to connect to the power source and receive electrical energy; the secondary winding serves as the output terminal, used to output electrical energy.
[0003] Since the core function of a transformer is voltage transformation, the primary and secondary windings are prone to having different numbers of layers, i.e., a difference in the number of layers between the primary and secondary windings. In practical applications, this difference in the number of layers between the primary and secondary windings will have the following effects:
[0004] Electromagnetic effects: Differences in the number of winding layers between the primary and secondary windings can alter the coupling degree, exacerbating leakage flux. Increased leakage flux leads to increased leakage inductance, which in turn affects the transformer's energy transfer efficiency. During operation, some energy is lost as leakage flux and cannot be effectively transferred to the secondary side, reducing the overall efficiency of the transformer. Furthermore, changes in leakage inductance can also worsen the stability of the transformer's output voltage, failing to meet the requirements of circuits with high voltage stability requirements.
[0005] Impact on insulation performance: Differences in the number of primary and secondary winding layers make it difficult to uniformly control the insulation distance between windings. On the side with more winding layers, the possibility of uneven stacking of insulation material is higher, resulting in a greater risk of localized insulation strength reduction.
[0006] Regarding heat dissipation: Different numbers of winding layers result in inconsistent heat dissipation conditions in the windings. Areas with more winding layers have poor heat dissipation, leading to localized hot spots. Prolonged exposure to high temperatures not only accelerates the aging of the insulation material and reduces its insulation performance, but also affects the mechanical properties of the windings, causing problems such as winding deformation and loosening.
[0007] The existing framework does not provide a solution for the difference in the number of primary and secondary winding layers, but only directly provides winding space, which is greatly affected by the difference in the number of primary and secondary winding layers. Utility Model Content
[0008] In view of this, the purpose of this application is to provide a skeleton for reducing the difference in the number of primary and secondary winding layers, in order to solve the problem that existing skeletons are easily affected by the difference in the number of primary and secondary winding layers.
[0009] To achieve the above technical objectives, this application provides a skeleton for reducing the difference in the number of primary and secondary winding layers, comprising: a skeleton body and a baffle;
[0010] The main body of the frame is provided with a primary winding area and a secondary winding area;
[0011] The baffle is slidably disposed on the main body of the frame to adjust the width of the primary winding area and the width of the secondary winding area.
[0012] Furthermore, the main body of the skeleton is provided with a narrow diameter region and a wide diameter region;
[0013] The diameter of the wide-diameter region is larger than that of the narrow-diameter region;
[0014] The primary winding region is located within the narrow diameter region;
[0015] The wide-diameter region is located within the secondary winding region.
[0016] Furthermore, the main body of the skeleton is provided with a first limiting block and a second limiting block;
[0017] The baffle is disposed between the first limiting block and the second limiting block;
[0018] The first limiting block and the second limiting block are used to limit the sliding stroke of the baffle.
[0019] Furthermore, the sliding stroke of the baffle is an integer multiple of the diameter of the winding wire.
[0020] Furthermore, on the main body of the skeleton, anti-slip texture is provided between the first limiting block and the second limiting block.
[0021] Furthermore, heat dissipation holes are provided on the main body of the frame in the secondary winding area.
[0022] Furthermore, the baffle is provided with a wire groove.
[0023] Furthermore, the baffle has a plum blossom ring structure.
[0024] Furthermore, the main body of the skeleton has multiple wire-locking holes in the primary winding area;
[0025] The plurality of the wire-locking holes are distributed at intervals along the circumference of the skeleton body;
[0026] The wire-locking holes are used for the corresponding wires to be locked in one by one.
[0027] Furthermore, the main frame body is provided with two secondary winding regions;
[0028] The two secondary winding regions are located on both sides of the primary winding region.

[0039] Please see Figure 1 and Figure 2 The present application provides a skeleton for reducing the difference in the number of primary and secondary winding layers, comprising: a skeleton body 10 and a baffle 20; the skeleton body 10 is provided with a primary winding area 11 and a secondary winding area 12; the baffle 20 is slidably disposed on the skeleton body 10 to adjust the width of the primary winding area 11 and the width of the secondary winding area 12.
[0040] In this embodiment, the skeleton body 10 can be a symmetrical structure. Specifically, the skeleton body 10 is provided with two secondary winding regions 12, and the two secondary winding regions 12 are symmetrically arranged on both sides of the primary winding region 11. Correspondingly, two baffles 20 are provided, and are symmetrically arranged on both sides of the primary winding region 11.
[0041] In this embodiment, the width of the primary winding region 11 refers to its dimension along the axial direction of the skeleton body 10, that is, along... Figure 1 The dimension along the X-axis. The width of the secondary winding region 12 refers to its dimension along the axial direction of the main body 10 of the frame, that is, along... Figure 1 The dimension along the X-axis. Correspondingly, the direction in which the baffle 20 can slide on the skeleton body 10 is the circumferential direction of the skeleton body 10.
[0042] During winding, based on the winding requirements, the operator can calculate the number of layers after winding according to the wire diameter, the width of the winding area 11, and the number of turns. Then, by adjusting the width of the primary winding area 11 and the width of the secondary winding area 12 using the sliding baffle 20, the difference in the number of layers after winding between the two can be changed.
[0043] This embodiment provides a sliding baffle 20 for adjusting the difference in the number of layers as follows: The width of the primary winding region 11 is 36mm, and the wire diameter is 5mm. Therefore, each layer of the primary winding region 11 can accommodate a maximum of 7 wires. When the required number of turns in the primary winding region 11 is 24, the primary winding region 11 needs to be wound in four layers (the inner three layers with 7 wires each, and the outermost layer with 3 wires). The width of the secondary winding region 12 is 21mm, and the wire diameter is 5mm. Therefore, each layer of the secondary winding region 12 can accommodate a maximum of 4 wires. When the required number of turns in the secondary winding region 12 is 8, the secondary winding region 12 needs to be wound in two layers (4 wires per layer). By sliding the baffle 20, the width of the primary winding region 11 is increased to 41mm, allowing each layer of the primary winding region 11 to accommodate a maximum of 8 windings, resulting in three winding layers (8 windings per layer). Correspondingly, the width of the secondary winding region 12 is reduced to 16mm, allowing each layer to accommodate a maximum of 3 windings, resulting in 3 winding layers (3 windings per inner two layers and 2 windings per outermost layer). By adjusting the baffle 20, the number of wires that can be accommodated in each layer of the primary winding region 11 and the secondary winding region 12 can be adjusted according to the layer requirements, thereby reducing the difference in the number of primary and secondary winding layers and correspondingly reducing the impact of the difference in the number of primary and secondary winding layers.
[0044] It should be noted that you should refer to [link / reference]. Figure 2 ,pass Figure 2 As shown in the number of wires per layer of the primary winding region 11, the number of wires that each layer can accommodate can be adjusted even when the width of the primary winding region 11 remains constant. For example, the inner second layer has 7 wires per layer, and the lower third layer has 6 wires per layer. This variation in the number of wires per layer is due to the fact that the windings can be positioned in the gaps between the windings of the previous layer. That is, in practical applications, the fixed-width primary winding region 11 can also adjust the number of wires per layer according to the placement of the windings. Based on this, this solution increases the adjustment threshold for the number of wires per layer in the primary winding region 11 and the secondary winding region 12 by using a sliding baffle 20. This improves the flexibility of adjusting the difference in the number of layers during winding, helps operators reduce the difference in the number of layers between the primary and secondary windings, and reduces the electromagnetic, heat dissipation, and insulation performance effects caused by the difference in the number of layers, further improving the overall performance and reliability of the transformer.
[0045] In practical applications, when winding the main body 10 of the skeleton, the primary winding area 11 is usually wound first. To this end, after adjusting the baffle 20 to a suitable position, the staff can hold the baffle 20 in place so that the baffle 20 cannot move.
[0046] In one embodiment, the skeleton body 10 is provided with a narrow diameter region 101 and a wide diameter region 102; the diameter of the wide diameter region 102 is larger than that of the narrow diameter region 101; the primary winding region 11 is disposed within the narrow diameter region 101; and the wide diameter region 102 is disposed within the secondary winding region 12.
[0047] Specifically, in practical applications, the number of turns required for the primary winding region 11 is often greater than that for the secondary winding region 12. The narrow diameter region 101 allows the primary winding region 11 to accommodate more turns within a limited space, reducing the situation where the outermost layer of the primary winding region 11 protrudes more than the outermost layer of the secondary winding region 12.
[0048] In a more specific embodiment, the skeleton body 10 is provided with a first limiting block 13 and a second limiting block 14; the baffle 20 is disposed between the first limiting block 13 and the second limiting block 14; the first limiting block 13 and the second limiting block 14 are used to limit the sliding stroke of the baffle 20.
[0049] In one implementation, the second limiting block 14 can be an annular stop, integrally formed with a portion of the primary winding area 11 of the skeleton body 1011. The first limiting block 13 can be stepped. The first limiting block 13 is disposed in the secondary winding area 12, so that part or all of the winding in the secondary winding area 12 can be wound on the first limiting block 13. Specifically, in this embodiment, the structure of the first limiting block 13 is a stepped protrusion on the secondary winding area 12, thus increasing the area where the first limiting block 13 is disposed, forming the aforementioned wide-diameter area 102.
[0050] When the baffle 20 slides close to the first limiting block 13, making it impossible to place the winding wire between the baffle 20 and the first limiting block 13, all the winding wires on the secondary winding area 12 can be wound within the wide diameter area 102 formed by the first limiting block 13.
[0051] When the baffle 20 slides away from the first limiting block 13, so that the gap between the baffle 20 and the first limiting block 13 can accommodate the winding, the winding of the secondary winding area 12 can be partially distributed in the area between the baffle 20 and the first limiting block 13, thereby flexibly adjusting the number of layers in the secondary winding area 12.
[0052] In one implementation, the sliding stroke of the baffle 20 is an integer multiple of the wire diameter. For example, in this embodiment... Figure 2 In the illustrated embodiment, the sliding stroke of the baffle 20 is twice the diameter of the winding wire.
[0053] In one embodiment, anti-slip texture 16 is provided on the skeleton body 10 between the first limiting block 13 and the second limiting block 14.
[0054] Specifically, the sliding area of the baffle 20 is named the sliding zone. The anti-slip texture 16 can effectively increase the friction between the baffle 20 and the frame body 10, prevent the baffle 20 from shifting during the winding process, ensure the stability of the winding area, and increase the firmness of the winding wound in the sliding zone.
[0055] In one embodiment, a heat dissipation hole 121 is provided on the secondary winding region 12 of the frame body 10, which can enhance the heat dissipation performance of the secondary winding region 12.
[0056] In one embodiment, the baffle 20 is provided with a wire passage groove 21. The wire passage groove 21 allows the wire to pass through when the winding needs to transition from the primary winding area 11 to the secondary winding area 12, thus preventing excessive bending or wear of the winding at the turning point.
[0057] In one implementation, the baffle 20 has a plum blossom ring structure.
[0058] In practical applications, the baffle 20 can be configured as two semi-ring-shaped structures. When the baffle 20 is assembled to the sliding area of the frame body 10, the two semi-ring-shaped structures can be joined to form a complete baffle 20. In practical applications, the frame body 10 is mostly made of engineering plastic, and correspondingly, the baffle 20 can also be made of engineering plastic. Correspondingly, the two semi-ring-shaped structures can be fastened together using plastic clips. The method of fastening the two semi-ring-shaped plastic parts together is existing technology and will not be described in detail in this embodiment.
[0059] As one implementation method, the main frame 10 can be a structure that is assembled from two parts. For example... Figure 3 As shown, a portion of the primary winding area 11 and a portion of the secondary winding area 12 are connected by a threaded structure. During assembly, the baffle 20 can be first inserted into the portion of the primary winding area 11, and then the portion of the primary winding area 11 and the portion of the secondary winding area 12 are aligned and tightened by the threaded structure, thereby limiting the baffle 20 between the first limiting block 13 and the second limiting block 14.
[0060] In one embodiment, the skeleton body 10 has a plurality of wire-locking holes 15 in the primary winding region 11; the plurality of wire-locking holes 15 are distributed at intervals along the circumference of the skeleton body 10; the wire-locking holes 15 are used for the corresponding insertion of the windings. The wire-locking holes 15 can improve the stability of the winding in the primary winding region 11.
[0061] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
