The resistance to pressure and impact resistance reduces external damage, prolongs the service life of high-voltage varistors, reduces the burden on the pins by using a fixed plug-in method, reduces the risk of pin bending and breaking during use, and avoids The problem of positional deviation and falling off of the high-voltage varistor improves the connection stability of the high-voltage varistor.

Description

technical field [0001] The invention relates to the technical field of electronic component accessories, in particular to a matching protection component of a high-voltage varistor. Background technique [0002] Varistor refers to a voltage-limiting element that responds sensitively to voltage changes. Its characteristic is that at a specified temperature, when the voltage exceeds a certain critical value, its resistance will decrease sharply, and the current passing through it will increase sharply. , The voltage and current are not in a linear relationship, and have excellent nonlinear volt-ampere characteristics. They are mainly used for voltage clamping when the circuit is subjected to overvoltage, and absorb excess current to protect sensitive devices. At present, varistors are divided into two categories: high-voltage varistors and high-energy varistors, which cannot be replaced by each other in terms of raw materials and performance. Among them, high-voltage varistor...

Problems solved by technology

[0003] However, most of the traditional high-voltage varistors do not have supporting protective components, and the performance of compression and impact resistance is insufficient. They are easily damaged by external forces during use, which inevitably shortens the service life of high-voltage varistors, and only rely on pin welding to fix them. , increases the burden on the pins, and the pins are prone to bending and breaking during use, resulting in the position of the high-voltage varistor shifting, and even falling off directly in serious cases, the connection stability is poor, and the structure is too simple, heat dissipation Low efficiency, high-voltage varistors are prone to overheating problems during use, resulting in damage to the insulation structure of high-voltage varistors, affecting the reliability of high-voltage varistors
