Problems solved by technology

[0006] However, in order to properly respond to corona and scratches, the aforementioned insulator needs to use different profiled materials on both sides. Due to its weak strength, it is easy to break during use and cause the performance of the high-voltage transformer to decrease.
[0007] Moreover, the covering operation for the primary coil 30 and the secondary coil 40 is also relatively complicated, thereby reducing production efficiency.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with drawings and embodiments.

[0019] Such as figure 2 As shown, the present invention includes an E-shaped magnetic core unit 110. The E-shaped magnetic core unit 110 is configured with a primary coil 130 and a secondary coil 140 through winding, and an injection-molded insulating member 150 is used to cover the primary coil 130 and the secondary coil. 140 on.

[0020] The material of the aforementioned injection molding insulating part 150 is PBT (Polybutylene Terephthalate) with good ductility, tensile force and strength, which is made of such as image 3 The shown U-shaped first insulator 150a and the second insulator 150b are combined with each other.

[0021] The central portion of the first insulator 150a is equipped with a side plate 152a with a thickness of 0.5mm and a length of 10mm. The upper end of the side plate 152a is an upper plate 154a with a thickness of 0.5mm and a length of 15m...

Abstract

The present invention relates to a high voltage transformer, in particular to a high voltage transformer with an injection molding insulative component, which includes an E-shaped unit with magnetic core (110), a secondary coil (140) of which the ratio between the primary coil (130) and the number of turns is greater than the ratio of the primary coil (130), an I-shaped unit with magnetic core (120) that is integrated at the lower side of the E-shaped unit with magnetic core (110) by welding or through mould, and an insulative component (150) that covers the primary coil (130) and the secondary coil (140) so as to keep the primary coil (130) and the secondary coil (140) insulative from the E-shaped unit with magnetic core (110). The present invention is characterized in that the insulative component (150) is molded by injection of the PBT material.

Description

technical field [0001] The invention relates to a high-voltage transformer, in particular to a high-voltage transformer with an injection-molded insulating part, which includes an injection-molded insulating part that can cover a primary coil and a secondary coil of the high-voltage transformer. Background technique [0002] Such as figure 1 As shown, in general, high-voltage transformers are suitable for devices that require high voltage, such as microwave oven magnetrons, and can generate high voltage. On the E-shaped magnetic core unit 10, the primary coil 30 and the number of turns are more than 30 turns of the primary coil. The secondary coil 40 of the E-type magnetic core unit 10 is fixed at the lower end of the I-shaped magnetic core unit 20, and the lower end of the I-shaped magnetic core unit 20 is fixed by welding to facilitate installation to other equipment, and the power input terminal is fixed. The primary coil 30 is connected to an AC power supply, and the hi...
