Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformers, in particular to a novel transformer with a U-shaped gasket. Background Art
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core (magnetic core). The iron core is a core component.
[0003] The existing transformer adopts the iron core structure disclosed in the patent document with publication number CN218866871U. Since the height of the first middle column on the first E-type plate determines the number of coils that can be wound, and the number of coils determines the strength of the inductance, the top surface of the first middle column is usually polished to adjust the height of the first middle column. At this time, a large gap will be left between the first middle column and the second E-type plate. Multiple coils and insulating sheets will be set on the first middle column. During assembly, the upper and lower adjacent coils will be separated by insulating sheets. The thickness of the insulating sheet is very thin, usually only a few tenths of a millimeter thick. Therefore, after the assembly is completed, the insulating sheet located at the top of the first and second middle columns is easy to detach from the gap between the first middle column and the second E-type plate and the second middle column and the I-type plate, affecting the insulation. At the same time, the coils on the first middle column are relatively loose with each other and cannot be pressed down to be compacted, which affects the inductance strength. In particular, the coil on the first E-type plate needs to be connected in series with the coil on the second E-type plate, so the coil will rub against the side of the second E-type plate, and the coil is prone to wear, thereby affecting the insulation between the coil and the second E-type plate. Utility Model Content
[0004] The utility model aims to solve the above problems and designs a new transformer with a U-shaped gasket, which solves the problems of poor insulation and inability to compact the coil in the existing iron core structure, thereby affecting the inductance strength.
[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a new type of transformer with a U-shaped gasket, which includes an I-type plate, a second E-type plate and a first E-type plate from top to bottom, a first middle column in the middle of the first E-type plate and a gap between the bottom surface of the second E-type plate, a second middle column in the middle of the second E-type plate and a gap between the bottom surface of the I-type plate, a plurality of coils and gaskets are sleeved on the first middle column, at least one coil and at least one gasket are sleeved on the second middle column, the coils and gaskets are arranged at intervals, all the coils are connected in series in sequence, a first partition is arranged on the top of the first middle column, the top surface of the first partition is in contact with the bottom surface of the second E-type plate, and the two sides of the first partition are bent toward the side where the second E-type plate is located and surround the two sides of the second E-type plate, and an insulating layer is arranged on the bottom surface of the I-type plate, wherein the first partition is made of insulating material.
[0006] Preferably, a through hole is provided in the middle of each of the first partitions, and the first center column is plugged into the through hole on the first partition.
[0007] Preferably, two sides of the first partition plate are bent to form an isolation portion, and the width of the isolation portion is consistent with the width of the groove on the second E-shaped plate.
[0008] Preferably, the shape of the first partition plate is adapted to the shape of the receiving groove on the first E-shaped plate.
[0009] Preferably, a second partition is provided on the top of the second center column, and the top surface of the second partition is in contact with the bottom surface of the I-type plate.
[0010] Preferably, the insulating layer is made of insulating tape, and the insulating tape is adhered to the bottom surface of the U-shaped plate.
[0011] Preferably, the gap between the second center column and the I-type plate is smaller than the thickness of the coil.
[0012] Compared with the prior art, the beneficial effects are:
[0013] The utility model has the advantages of simple structure and easy assembly. The first partition is sandwiched between the topmost coil of the first middle column and the second E-type plate. The first partition firmly presses the coil and the gasket on the middle column to prevent the coil and the gasket from bouncing up. The first partition plays an insulating role. At the same time, an insulating layer is arranged on the bottom surface of the I-type plate to isolate the coil on the second middle column from the I-type plate. The gasket will not fall off the second middle column. The tightness of the assembly of the coil and the gasket is higher, which improves the overall stability of the core structure and prevents the coil and the gasket from popping out of the middle column.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] like Figure 1 As shown, a preferred embodiment of the utility model proposes a new type of transformer with a U-shaped gasket, and the core structure includes three layers from top to bottom, namely: an I-type plate 1, a second E-type plate 2 and a first E-type plate 3, wherein a first middle column 31 is arranged in the middle of the first E-type plate 3, and a second middle column 21 is arranged in the middle of the second E-type plate 2, so that the shape of the first E-type plate 3 and the second E-type plate 2 is "E" shaped, so that a receiving groove for accommodating the coil 5 and the gasket 6 is formed on the first E-type plate 3 and the second E-type plate 2. The top end surface of the first middle column 31 and the second middle column 21 is a grinding surface, and a certain gap is left between the grinding surface and the bottom surface of the second E-type plate 2 and the I-type plate 1. The grinding surface can be polished according to needs to adjust the height of the first middle column 31 and the second middle column 21.
[0024] refer to Figure 2 , a plurality of coils 5 and a plurality of gaskets 6 are sleeved on the first middle column 31, the gasket 6 is an insulating sheet, the coil 5 is separated from the first E-shaped plate 3 by the gasket 6, and the coils 5 are also separated from each other by the gasket 6. At least one coil 5 and at least one gasket 6 are sleeved on the second middle column 21, and the gasket 6 separates the coil 5 from the second E-shaped plate 2. The coils 5 on the first E-shaped plate 3 are connected in series in sequence, and then connected in series with the coils 5 on the second E-shaped plate 2.
[0025] refer to Figure 1 , Figure 5A first partition 4 is provided between the coil 5 on the top layer of the first middle column 31 and the second E-shaped plate 2. The first partition 4 is made of insulating material, which can be plastic, bakelite or other insulating materials. Its function is the same as that of the gasket 6, which is to block insulation. A through hole is provided in the middle of the first partition 4. The first middle column 31 is plugged into the through hole to position the first partition 4 and prevent the first partition 4 from moving at will. The top surface of the first partition 4 is tightly attached to the bottom surface of the second E-shaped plate 2, so that the multiple coils 5 on the first middle column 31 can be pressed down and compacted, and the coils 5 will not be loose, which will not affect the inductance strength.
[0026] The two ends of the first partition 4 are bent vertically upward to form an isolation portion 41, so that the overall shape of the first partition 4 is "U"-shaped. The isolation portion 41 surrounds and blocks the two sides of the second E-shaped plate 2, and the width of the isolation portion 41 is consistent with the width of the receiving groove on the second E-shaped plate. In this way, when the coil 5 on the first E-shaped plate 3 is connected in series with the coil 5 on the first E-shaped plate 3, the coil 5 will not contact the two sides of the second E-shaped plate 2, and the first partition 4 can insulate the coil 5 to prevent the coil 5 from contacting the surface of the second E-shaped plate 2.
[0027] The shape of the first partition plate 4 is not limited to Figure 5 This can also be Figure 6 The shape of the one shown is determined according to the shape of the receiving groove on the first E-shaped plate 3.
[0028] refer to Figure 3 The gap between the second center column 21 and the I-shaped plate 1 is smaller than the thickness of the coil 5, so that the coil 5 sleeved on the second center column 21 cannot escape from the gap.
[0029] refer to Figure 4 An insulating layer is provided on the bottom surface of the I-shaped plate 1 to isolate the coil 5 on the second center column 21 from the I-shaped plate 1. The insulating layer adopts an insulating tape 11. The insulating tape 11 is pasted on the bottom surface of the I-shaped plate 1, which plays an insulating role and is not easy to fall off. If the gasket 6 is used, it is easy to fall off from the second center column 21 because the gasket 6 is very thin.
[0030] In other technical solutions, the insulating layer may also be a partition, such as Figure 7 As shown, the partition is the second partition 7, and the function of the second partition 7 is the same as that of the first partition 4. The thickness of the second partition 7 is relatively thin, and is slightly larger than the gap between the second center column 21 and the I-shaped plate 1. A through hole is also provided in the middle of the second partition 7, and the second center column 21 is plugged into the through hole. The top surface of the second partition 7 is tightly attached to the bottom surface of the I-shaped plate 1, so that the coil 5 on the second center column 21 can be pressed tightly.
[0031] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
