High voltage cable insulation structure of high voltage transformer

Abstract

The invention provides an insulating structure for high-voltage wires in a high-voltage transformer. The secondary coil of the high-voltage transformer and the high-voltage wires are crimped through connecting terminals and conducted by the connecting terminals. It also includes an insulating device made of synthetic resin. A fold line that is thinner than other parts is formed in the transverse direction, and terminal fitting grooves are respectively formed in the transverse direction on the covers on both sides arranged across the folding line, and the two sides of each terminal fitting groove are respectively formed with their intervals and connecting terminals. The anti-off protruding parts with the same length, the upper part of the terminal fitting groove of the one side cover is formed with a plurality of stopper protrusions, and the same part of the other side cover is correspondingly formed with stopper grooves, the insulating structure will connect The terminal is attached to the side surface of the secondary coil in a state of being accommodated in the terminal fitting groove inside the insulating device. In this way, not only can the junction between the secondary coil and the high-voltage line be insulated smoothly without movement, but also the durability of the junction can be improved, reliability can be ensured, and the appearance can be improved.

Description

technical field [0001] The present invention relates to an insulation structure of a high-voltage wire in a high-voltage transformer, and in more detail, relates to an insulating device made of synthetic resin that joins a high-voltage wire and a coil by crimping to accommodate the crimping portion with a uniform length Among them, the insulation structure of the high-voltage line that insulates the joint between the high-voltage line and the coil from the coil. Background technique [0002] As we all know, a high-voltage transformer is a device used to generate high voltage for a device that requires high voltage, such as a magnetron of a microwave oven. It is composed of a primary coil and a secondary coil with a higher winding ratio on the E-shaped core. , the I-type iron core is fixed on the lower part of the E-type iron core, the lower part of the I-type iron core is fixed with a bracket for installing other devices by welding, the power input terminal is formed on the ...

Problems solved by technology

[0007] However, as mentioned above, although the work efficiency and productivity are improved by crimping the 2nd-stage coil and the high-voltage wire through the connection terminal, and the manufacturing time and manufacturing cost are reduced, since the junction between the 2nd-stage coil and the high-voltage wire remains the same as before Wrapped in insulating paper and fixed to one side of the secondary coil, the insulating paper is still characteristically easy to break, and the reliability is reduced due to the difference in insulation depending on the thickness of the insulating paper, and it is difficult to improve the appearance.
