Safety resistor

The utility model discloses a safety resistor which comprises a resistor body, resistor measuring heads are arranged at the two ends of the resistor body, the diameter of each resistor measuring head is larger than that of the resistor body, the resistor measuring heads and the resistor body are integrally fixed, and a plurality of color rings are arranged on the outer wall of the resistor body at equal intervals. And a supporting base of which the width size is the same as the diameter size of the resistor measuring head is arranged above the resistor measuring head. According to the utility model, the resistor main body can be prevented from being in direct contact with the circuit board through the support base and the separation protection plate, so that the circuit on the PCB can be protected, and even if the resistor main body is burnt, the circuit on the PCB can be prevented from being damaged by the high-temperature resistor main body; the PCB circuit board is provided with the partition protection pl
