Abstract
The utility model relates to an iron core lamination with a wide frame, which is used for a transformer. The utility model is in an E-shaped structure or a structure in the shape like the Chinese character 'shan'. The utility model is characterized in that the proportion of the width A of the frame of the utility model to the tongue width B of the utility model is 0.8 to 2.4. The utility model can reduce the magnetic leakage of the outside of the transformer, reduce the noise of a power transformer and the interference to the exterior and improve the signal transmission quality of an audio transformer. The utility model is suitable for being used as the iron core of a transformer and an electrical inductor.
Description
The utility model relates to a kind of core structure of transformer.
At present, it is wide that the E type that transformer uses or the border width of mountain font core lamination stack are narrower than tongue, and standard design is 0.5-0.68 (ratio that frame is wide with tongue).For traditional transformer, after the requirement of having satisfied no-load voltage ratio and power, another important techniques index is exactly that requirement has high signal transmission quality and power supply degree of purity preferably.People are in order to improve the performance of transformer, generally start with from coil winding method and aspects such as the technology of selecting improvement for use and material, but the improvement by for many years still can not make audio frequency transformer reach comparatively desirable audio signal transmission effect in the HD Audio scope.
The purpose of this utility model is to provide a kind of outside leakage flux of transformer that reduces, and improves the broadside frame transformer core lamination of transformer performance.
Core lamination stack of the present utility model is E type or mountain font, it is characterized in that: the border width a of described core lamination stack is 0.8-2.4 with the ratio of the wide b of its tongue.
Owing to adopted broadside frame transformer core lamination, for reducing the outside leakage field of transformer, reduce the power transformer electrical noise and, improve audio frequency transformer signal transmission quality etc. the interference of outside, all have comparatively obvious effects.
The drawing explanation:
Accompanying drawing is a structural representation of the present utility model.
A is a border width in the accompanying drawing, and b is that tongue is wide, wherein a: b is between 0.8-2.4.Most preferred embodiment of the present utility model is a: b=1.6.The utility model is applicable to the iron core of transformer and inductance.
