Abstract
Description
Technical Field
[0001] The utility model relates to technical fields such as servers, communication power supplies, industrial control, etc., and in particular to a new skeleton structure for a flat-plate transformer. Background Art
[0002] The transformer skeleton, also called the transformer wire frame, is a component of the main structure of the transformer. In the conventional transformer skeleton structure, the core column is insulated by adding NOMEX or tape as a sleeve, and a bottom plate is set at the bottom of the core column. The NOMEX sleeve and the bottom plate need to be processed separately in the factory and then installed on the core after processing. However, there is a gap between the sleeve and the bottom plate on the core, which will expose part of the bottom of the core. Therefore, only basic insulation can be achieved between the secondary winding and the core.
[0003] As can be seen from the above, the main defects in the existing technology of transformer skeleton are that the base plate and NOMEX sleeve need to be processed separately when in use, which increases the production process and production time; secondly, there is a gap between the base plate and the sleeve, which can only provide basic insulation and cannot be used in AC to AC high voltage circuits. Utility Model Content
[0004] In view of the defects in the prior art, the utility model provides a new skeleton structure for a flat-plate transformer to reduce the processing steps of the skeleton in the flat-plate transformer and reduce the labor cost. It can be used not only in AC to DC low-voltage circuits, but also in AC to AC high-voltage circuits.
[0005] The utility model provides a novel skeleton structure for a flat-plate transformer, comprising: a base, a magnetic core center column is arranged on the base, a skeleton is sleeved on the outer periphery of the magnetic core center column, the skeleton comprises a bottom plate, the bottom plate is abutted against the base, a through hole is arranged on the bottom plate for the magnetic core center column to pass through, the inner edge of the through hole extends to form a sleeve, and the sleeve is sleeved on the outer periphery of the magnetic core center column.
[0006] It can be seen from the above technical solution that the utility model provides a new skeleton structure for a flat transformer. During processing, the sleeve and the bottom plate that originally need to be processed separately are connected into an integral skeleton, which simplifies the production process and reduces the production cost; there is no gap between the skeletons connected as a whole when the sleeve and the bottom plate are used separately, so that the insulation effect is enhanced, so that it can be used not only in AC to DC low-voltage circuits, but also in AC to AC high-voltage circuits. Secondly, when the skeleton is set outside the core center column, it can also protect the core center column, effectively reducing the damage of the core to the external collision, friction, etc.
[0007] Optionally, the core center column is located in the middle of the base. The core center column being located in the middle can provide a larger area window, which is beneficial for heat dissipation and can improve the power handling capacity of the core.
[0008] Optionally, the bottom plate is annular; baffles are provided on both sides of the magnetic core center column on the base, and grooves are provided on one side of the two baffles close to the magnetic core center column, and part of the outer edge of the bottom plate is embedded in the groove.
[0009] Optionally, the cross-sectional shape of the central column of the magnetic core is circular, rectangular or elliptical.
[0010] Optionally, the height of the core center column is lower than the height of the frame. When the height of the core center column is lower than the height of the frame, a space is formed in the frame, which is conducive to air circulation and further improves the heat dissipation effect.
[0011] Optionally, the sleeve is integrally formed with the base plate.
[0012] Optionally, the bottom plate and the sleeve are connected in a smooth transition. The sleeve and the bottom plate are connected in a smooth transition, which effectively reduces damage to the frame during operation and increases the service life of the frame.
[0013] Optionally, the frame is made of bakelite. The plastic bakelite material can work stably for a long time in a high temperature environment, which can ensure that the transformer is not affected in a high temperature environment, and the material has good insulation performance, which can effectively reduce the risk of leakage and the like.

[0023] Figure 1 A schematic structural diagram of a novel skeleton structure for a flat-plate transformer provided in one embodiment of the utility model.
[0024] like Figure 1As shown, a new skeleton structure for a flat transformer provided in this embodiment includes a base 3, on which a magnetic core column 2 is arranged, and a skeleton 1 is sleeved on the outer periphery of the magnetic core column 2. The skeleton 1 includes a bottom plate 102, which is in contact with the base 3. A through hole is arranged on the bottom plate 102 for the magnetic core column 2 to pass through, and the inner edge of the through hole extends to form a sleeve 101, which is sleeved on the outer periphery of the magnetic core column 2. During processing, the sleeve 101 and the bottom plate 102 are integrally formed, and the bottom plate 102 and the sleeve 101 are smoothly transitionally connected, so that it can reduce the damage to the skeleton during operation and increase the service life of the skeleton. During installation, the integrally formed skeleton is sleeved on the magnetic core column 2, wherein the magnetic core column 2 is located in the middle of the base 3, so that it can provide a larger area window, which is conducive to heat dissipation and can improve the power handling capacity of the magnetic core. When the height of the core center column 2 is lower than the height of the frame 1 , a space is formed inside the frame, which is conducive to air circulation and further improves the heat dissipation effect.
[0025] It should be noted that the cross-sectional shape of the core center column 2 is circular, rectangular or elliptical. In this embodiment, the cross-sectional shape of the selected core center column 2 is cylindrical, which avoids the hidden danger of damaging the skeleton insulation material due to the corners of the rectangular parallelepiped during use compared with the rectangular parallelepiped center column; compared with the elliptical center column, the circular center column can provide a larger area window, so that the heat dissipation effect is enhanced.
[0026] Specifically, the frame 1 is made of bakelite. Bakelite is the common name for phenolic plastic, which is a synthetic plastic material. Plastic bakelite material can work stably for a long time in a high temperature environment, which can ensure that the transformer is not affected in a high temperature environment, and the material has good insulation properties, which can effectively reduce the risk of leakage.
[0027] This embodiment provides a novel skeleton structure for a flat-plate transformer, wherein the bottom plate 102 is annular; baffles 301 are provided on both sides of the magnetic core column 2 on the base 3, and grooves are provided on the sides of the two baffles 301 close to the magnetic core column 2, and part of the outer edge of the bottom plate 102 is embedded in the grooves. In this embodiment, the grooves on the inner side of the baffles 3 can limit the sliding of the bottom plate and further fix the skeleton.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
