High impact resistant fusing resistor

耐强冲击型熔断电阻器

Abstract

The utility model provides a high impact resistant fusing resistor, which comprises an insulating substrate. Two metal caps are arranged at two ends of the insulating substrate respectively, a resistance film is arranged on the insulating substrate in a cylindrical structure, two ends of the resistance film are connected with the metal caps at the two ends of the insulating substrate respectively, two pins are externally connected with the metal caps at the two ends of the insulating substrate respectively, and a radiation layer is arranged on the outer layer of the insulating substrate and wraps the resistance film. The high impact resistant fusing resistor is simple in structure, low in cost and resistant to high impact, the fusing time of the resistance film is within 1-30 seconds when the current is 36 times of the rated current, the fusing time of the resistance film is within 0.2-2 seconds when the current is 225 times of the rated current, and the fusing time of the resistance film is within 20-200 milliseconds when the current is 900 times of the rated current.
