Transformer framework, transformer, power supply and transformation production method

Abstract

The invention discloses a transformer framework, a transformer, a power supply and a transformation production method, wherein the transformer framework comprises a winding column, two side plates andtwo safety gauge edges which are integrally formed, wherein the two safety gauge edges are arranged on the two axial sides of the wire winding column; the side plates are connected to the axial outerside of the safety gauge edges; and a wire passing groove is formed in the safety gauge edge at the at least one side and the side plate on the same side. Therefore, the winding column, the two sideplates and the two safety gauge edges are matched, the full-automatic production mode of the transformer can be realized, the production efficiency can be improved, and the product quality consistencycan also be improved; in addition, the structure of the transformer framework is simple, and the procedures are simple, so that the manufacturing cost can be lowered; and meanwhile, the transformer can meet the safety requirements at home and abroad, so that the application range of the transformer can be expanded, and the universality and practicability of the transformer can be better.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer skeleton, a transformer, a power supply and a method for producing a transformer. Background technique [0002] In the electronic products of high-frequency switching power supply, none of the transformer skeletons used in the structural design can completely avoid safety regulations. They are all physically isolated during the winding process of the transformer in the later stage to increase safe distance. [0003] In related technologies, the most common ways to increase the safety distance are the following two ways: one is to put Teflon bushings on the cross-contact position of the primary side winding and the secondary side winding of the transformer frame to isolate or paste anti-folding tape for isolation; At least one side of the trunking of the transformer skeleton is added with a retaining wall tape to increase the safety distance, and the width of t...

AI Technical Summary

Problems solved by technology

[0004] The above two physical isolation methods can effectively avoid safety regulations, but the cost of manpower and materials invested in the whole process is high, and there are great hidden dangers in the manufacturing process. As a result, the transformer process structure does not meet the requirements of safety standards

The risk is high, and it is easy to cause an increase in the rate of customer complaints, affect the corporate image, and cause damage to interests

The main disadvantage is that this method can only be in the semi-automatic production mode, resulting in low production efficiency, high cost and long cycle
