Embodiment 1

[0041] See Figure 1 to 11 In this embodiment, a transformer skeleton with built-in multilayer circuits includes a skeleton body molded from insulating plastic injection molding. The skeleton body is provided with n layers of metal sheets and plastic layers that play a role of conducting electricity. n is a natural number greater than 1, n Layers of metal sheets are stacked in the frame body at intervals. In this embodiment, 4 layers of metal sheets are preferred, including a first metal sheet 1, a second metal sheet 2 located on the inner side, and a third metal sheet 3 and a fourth metal sheet 4 located on the outer side, in the order from top to bottom. The three metal sheets 3, the second metal sheet 2, the first metal sheet 1 and the fourth metal sheet 4, and the first metal sheet 1 and the second metal sheet 2 are electrically connected, and the third metal sheet 3 and the fourth metal sheet 4 are electrically connected. connection.

[0042] The metal sheet includes an ann...

Embodiment 2

[0059] See Figure 12 to 13 The transformer skeleton with built-in multilayer circuit in this embodiment is basically the same as the first embodiment. The difference lies in: the first metal sheet 1 and the second metal sheet 2 in the transformer skeleton with built-in multilayer circuit in this embodiment The connecting portion 81 extends to the outside of the first injection layer 5 and then bends downward to form a pin 8, and the extension direction of the pin 8 is the same as the extension direction of the remaining pins 8 of the first metal sheet 1 and the second metal sheet 2 the same.

[0060] The transformer skeleton with built-in multilayer circuit of the present invention uses metal sheets to replace the existing flat winding or the PCB form with copper foil attached to the surface, which not only has good overall performance and effect, but also reduces the cost of the existing transformer; The metal sheet has a large cross-sectional area, which can be applied to hig...

Abstract

The invention discloses a transformer framework internally provided with a multilayer circuit and a preparing method thereof. The transformer framework comprises a framework body which is formed by injection molding of insulating plastics, the framework body is internally provided with n layers of metal sheets and plastic layers, wherein the metal sheets play a conducting effect, n is a natural number larger than 1, and n layers of the metal sheets are arranged at intervals in the framework body in a laminating mode. The transformer framework internally provided with the multilayer circuit issmall in height and small in size, is integrally formed and can play a better insulating and protecting effect, the cross section of the metal sheets is large, the transformer framework can be appliedto the situations of high voltage and high current, and the requirements of different industries can be met.

Description

Technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer skeleton with built-in multilayer circuits and a preparation method thereof. Background technique [0002] With the development of society and the progress of science and technology, more and more electronic and electrical products enter the production and life of the people. Electronic and electrical products include a lot of magnetic components, and transformers are very important magnetic components. In recent years, as the requirements for lighter and thinner electronic and electrical products continue to increase, the design and use of transformers have become particularly important. [0003] As an important part of the transformer, the transformer skeleton includes a skeleton body and the metal in the skeleton body. In the prior art, in order to reduce the height of the transformer, most of the methods adopted are flat winding or PCB form with copper foil atta...
