Problems solved by technology

[0008] The purpose of the present invention is to solve the insulation isolation between the ceramic part and the resistance band or resistance sheet in the existing chip resistor, and the phenomenon of shortening the creepage distance in the rain environment is easy to occur when a single porcelain part is used, thus affecting the resistance of the resistance unit in the rain. The insulation performance in the environment cannot meet the high-voltage requirements in the rainy environment. A new type of chip resistor structure is proposed. The resistance band or resistance plate isolation insulation method of this chip resistor structure can effectively solve the resistance band or The isolation and insulation between the resistors has the problem of shortening the creepage distance in the rain environment, effectively improving the insulation performance of the resistance unit in the rain environment, and meeting the high voltage resistance requirements of the resistance unit in the rain environment

Abstract

A resistor that uses an integral porcelain tube to isolate resistance elements, including a frame, and a resistance unit is installed in the frame, and the resistance unit is fastened to the frame through a support; In the formed chip resistance unit, the resistance strips in the resistance unit or the upper and lower ends of the resistance plate are separated and positioned through the integral porcelain tube. On the outer surface of the integral porcelain tube, slots are set according to the arrangement spacing of the resistance bands or resistance sheets of the resistance unit. Or the isolation and positioning are formed between the end parts of the resistor sheet. The invention directly snaps the integral porcelain tube into the opening groove of the resistance band or the resistance plate, realizes the isolation and positioning of the resistance band or the resistance plate, increases the creepage distance of the resistance band or the resistance plate, and improves the insulation performance of the resistor.

Description

technical field [0001] The present invention relates to a structure of a resistor, in particular to an insulating structure between resistance bands or resistance plates of a chip resistor, which can effectively improve the resistance between resistance bands or resistance plates of a chip resistor. The insulation performance increases the creepage distance and withstand voltage value of a resistance band or a resistance sheet; it belongs to the technical field of chip resistor manufacturing. Background technique [0002] Chip resistor is a very widely used resistor. For example, on the current electric locomotive, in order to make the high-speed train or high-speed rail brake at a smooth speed, it is necessary to convert the kinetic energy and potential energy through the braking resistor. The generated electric energy is quickly converted into heat energy and dissipated in the air, so that the vehicle can be decelerated quickly and reliably, and the braking resistor used o...
