Abstract
The utility model relates to a sealed converter, which comprises a converter shell and a converter core. The converter core is sealed with epoxy resin between the converter core and the converter shell. The converter shell is provided with a plurality of elastic shrinkage cavities which reserve space for expansion of the converter shell due to temperature rise at work. The utility model has an advantages of avoiding deformation or damage of the converter shell when material produces heat.
Description
Technical field
The utility model relates to a kind of AC/DC convertor, and is especially relevant with the shell mechanism of the low power AC/DC convertor of household low pressure.
Background technology
Converter of the prior art, its the most normal structure is direct cover one converter shell body outside the converter movement normally, housing plays a part to isolate with movement, and its outer shell construction is generally the uniform cavity of wall thickness, so in use, expand because of the material heating that permanent work of converter or chemical reagent etc. cause, will cause the distortion or the breakage of shell body, thereby influence the useful life of converter.
The utility model content
The utility model is intended to solve existing problem in the prior art, provides a kind of the expansion for material heating to leave certain space, has the sealing converter of elastic shrinkage hole shell.
A kind of sealing converter of the utility model comprises converter shell and converter movement, and the converter movement places in the converter shell, between it, to the sealing of converter movement, has elastic shrinkage hole at the converter shell by epoxy resin.
After adopting said structure, during use, when making ambient temperature raise at work, converter causes the material heating, or chemical reagent causes material heating, and when causing the converter shell to expand, because the converter shell has the elastic shrinkage hole, for the expansion of converter shell leaves certain space, therefore when the material adstante febre, the converter shell can not be out of shape because of expansion, more can be not damaged because of expansion.
