Impact-resistant belt type resistor

The invention relates to the technical field of resistors, in particular to an anti-impact belt type resistor which comprises a plate-shaped insulating base and a plurality of strip-shaped metal resistance belts, a plurality of clamping grooves are formed in the surface of the insulating base, each resistance belt comprises a bent part located in the middle and positioning parts located on the two sides, and the clamping grooves are formed in the middle of the insulating base. The positioning parts are respectively and tightly embedded in different clamping grooves; the insulating base is provided with a supporting bulge which is attached to and supports the bending part; and an air blowing hole is formed in the insulating base and penetrates through the surface of the supporting bulge so as to blow air to the resistance tape. Compared with the prior art, the two adjacent resistance bands cannot be attracted, and a good current impact resisting effect can be achieved. The blow holes can promote heat dissipati
