Transformer coil cover for preventing short-circuit of coil

Abstract

The invention provides a transformer wire package which avoids the short circuit of a coil and is composed of a winding frame and the coil which is winded on the winding frame; the coil consists of a high-voltage coil and a low voltage coil, wherein, the high-voltage coil consists of a high-voltage winding and a strand wire section which is arranged at the end of the high-voltage winding; the winding frame comprises a hollow body and a pin base which consists of a high-voltage coil pin base and a low voltage coil pin base, the hollow body which consists of a hollow frame cylinder and a group of separation plates which are arranged in the axial direction of the external edge of the hollow frame cylinder so as to divide the axial direction of the external edge of the hollow frame cylinder into a plurality of winding trough sections; a winding trough adjacent to the high-voltage coil pin base is taken as a buffer trough; one end of the strand wire section is fixed on the high-voltage coil pin base and other strand wire sections are winded and received in the buffer trough; the high-voltage winding is winded in the winding trough corresponding to the high-voltage coil. The proposal ofthe invention solves the problem in the prior art that the strand wire section on the winding frame contacts the high voltage winding, thus avoiding the short circuit situation and improving the quality and qualified rate of the transformer.

Description

technical field [0001] The invention relates to a transformer wire bag, in particular to a transformer wire bag which can avoid coil short circuit. Background technique [0002] A transformer is a commonly used electronic component that is often used to step up or step down voltage in electronic circuits. The structure of a transformer is generally composed of three parts: a winding frame, a coil and an iron core, among which the winding frame and the coil form a transformer wire package. like figure 1 As shown, the winding frame is composed of a hollow frame tube 10, spacer plates 20, 21, 22, 23, 24 vertically connected to the hollow frame tube 10, and pin seats 30, 31 respectively. The spacer plate 24 and the spacer plate 20 are respectively Connected with the pin base 31 and the pin base 30, winding slots 50, 51, 52 and 53 are sequentially formed between the spacer plates 20 and 21, between 21 and 22, between 22 and 23, and between 23 and 24 . The hollow part of the h...
