Summary: | The utility model discloses an explosion-proof paper piece for a resistor. The explosion-proof paper piece comprises a circular-rectangular paper board, wherein explosion-proof bolt through holes are formed in the left end and the right end of the paper board respectively; four radial limit grooves are formed in the periphery of each explosion-proof bolt through hole; an air hole is formed in the central position of the paper board; the paper board is formed by stacking multilayer paper pieces which are an anti-slide pattern layer, a reinforcing layer and an explosion-proof layer sequentially from top to bottom. The explosion-proof paper piece disclosed by the utility model is formed by pressing and stacking multilayer paper pieces, and the four limit grooves are formed in the periphery of each explosion-proof bolt through hole to cooperate with a limit baffle on an explosion-proof bolt, so as to fix the explosion-proof bolt and prevent the loosening phenomenon of the explosion-proof bolt. |
