High-temperature circuit breaker for electric automobile power detection

Abstract

The invention relates to the technical field of high-temperature circuit breakers and particularly relates to a high-temperature circuit breaker for electric vehicle power detection. The high-temperature circuit breaker comprises a circuit breaker body, a dust removal mechanism, an extrusion mechanism, a positioning mechanism, an abutting mechanism and a fixing mechanism. Under the action of the fixing mechanism, the circuit breaker body can be conveniently and quickly connected with equipment, subsequent disassembly and replacement are further facilitated, meanwhile, heat dissipation and dustremoval of the circuit breaker body are facilitated under the action of the dust removal mechanism, the heat dissipation effect is better, under the action of the extrusion mechanism, an external electric wire can be conveniently and quickly connected with the circuit breaker body, meanwhile, the situation of wire falling caused by sliding damage or shaking is effectively prevented, the wire canbe clamped more firmly under the action of the abutting mechanism, the wire and the breaker body can be conveniently and rapidly inserted and connected under the action of the positioning mechanism, loosening and falling off of the wire during connection are prevented, meanwhile, the wire is protected, and wire abrasion is prevented.

Description

Technical field [0001] The invention relates to the technical field of high-temperature circuit breakers, in particular to a high-temperature circuit breaker for electric vehicle power detection. Background technique [0002] The breaker is composed of a breaker contact and a breaker cam fixed on the bottom plate of the breaker. The bottom plate of the breaker consists of two parts: a fixed bottom plate and a movable bottom plate. The function of the breaker is to periodically turn on and off the primary circuit of the ignition coil. It is generally composed of electric shock and power-off cams. The contact pair of the breaker is made of tungsten alloy. The contact is a fixed contact, and the other is a movable contact. The fixed contact grounding is realized by fixing screws on the movable bottom plate and the lower fixed bottom plate. The contact gap can be adjusted by rotating the eccentric screw; The contact is fixed on one end of the contact arm, the other end of the contac...

AI Technical Summary

Problems solved by technology

[0003] With the advancement of science and technology, there are many types of breakers. High-temperature breakers need to be used when monitoring electric vehicle power. When a short circuit occurs in the power or a fault generates high temperature, the breaker will cut off the power supply, reducing the occurrence of accidents. However, the traditional high-temperature breaker has a single structure. When connecting the circuit, it is usually connected by bolts one by one. This is inefficient, and it is easy to cause the bolts to slip, which makes it inconvenient to disassemble. It is also inconvenient to quickly connect with the device during installation. Disassembly, and at the same time, the accumulation of dust is inconvenient to clean during heat dissipation, which affects the efficiency of heat dissipation
