Bobbin bracket structure of transformer

Abstract

The invention discloses a structure for transformer bobbin bracket, which takes a shape of a hollow pipe body. A plurality of separators are arranged on the transformer bobbin bracket and at least one trans-line groove is arranged on the separator and used for providing space for the coil to cross the separator; the trans-line groove is designed to be slantingly tangent with the separator so as to increase the laying distance of the coil, and the depth of the trans-line groove presents a slant shape or ladder shape which is higher at one side and lower at the other side to ensure that the line of the coil enters at a higher position and goes out at a lower position when the lines of the coil are laid so as to increase the relative distance between two neighboring groups of coils of the separator, thereby effectively increasing the withstanding voltage of the separator of the bobbin bracket and relatively shortening the thickness of the separator of the bobbin bracket so as to further shorten the size of the transformer.

Description

technical field [0001] The invention relates to a winding frame structure of a transformer, in particular to a single winding frame of a transformer, on which multiple groups of coils can be wound, and the withstand voltage between each group of coils can be increased, and the volume of the transformer can be reduced. frame structure. Background technique [0002] A transformer is a commonly used electronic component. Generally, power supply circuits, frequency conversion circuits, etc. need to use transformers, which can be used to increase or decrease the voltage on electronic circuits, such as LCD monitors (LCD Monitor) or LCD TVs ( LCD TV), its backlight module must use multiple small transformers to drive and light multiple cold cathode tubes, and the transformers used must be reduced as much as possible. [0003] As shown in Figure 1, the transformer 1 in the LCD backlight module is provided with a winding frame 2, and the winding frame 2 is provided with a plurality ...

AI Technical Summary

Problems solved by technology

[0003] As shown in Figure 1, the transformer 1 in the LCD backlight module is provided with a winding frame 2, and the winding frame 2 is provided with a plurality of spacer plates 3, which can wind multiple groups of coils ( not shown in the figure), to drive multiple groups of cold-cathode tubes, the spacer 3 must be able to withstand high voltage, so the spacer 3 must be thickened, so that the volume of the bobbin 2 is limited, so how to reduce the size of the transformer The volume of the winding frame 2 and the ability to increase the withstand voltage of the winding frame partition plate 3 have become problems that transformer manufacturers must overcome.
