Transformer framework, transformer, power supply and transformer production method

Abstract

The invention discloses a transformer framework, a transformer, a power supply and a transformer production method, wherein the transformer framework comprises a winding column, a first side plate, asecond side plate and a first safety gauge edge, wherein the first side plate and the second side plate are connected to the first side and the second side of the axial direction of the winding column; the first safety gauge edge is arranged on the inner side of the first side plate; a plurality of first wire passing grooves are formed in the first side plate, and a plurality of second wire passing grooves are formed in the first safety gauge edge; the second wire passing groove located at the outermost edge is provided with a primary side winding, and the outer edge of the second wire passinggroove for allowing the primary side winding to pass through and located at the outmost edge is a first outer edge, wherein the first outer edge of the second wire passing groove does not exceed thewinding center, close to the second wire passing groove, of the secondary side winding. Therefore, by arranging the first safety gauge edge, the full-automatic production mode of the transformer can be realized, and the production efficiency can be improved; and in addition, the structure of the transformer framework is simple, the process is simple, and therefore the manufacturing cost can be lowered.

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
