Anti-overcurrent anti-surge protector

The utility model relates to an anti-overcurrent anti-surge protector. The anti-overcurrent anti-surge protector comprises a flame-retardant explosion-proof housing and pressure-sensitive resistors arranged in the flame-retardant explosion-proof housing. The portion between the pressure-sensitive resistors and the flame-retardant explosion-proof housing is filled up with an insulation explosion-proof material, two of the three pressure-sensitive resistors are aslant arranged in the flame-retardant explosion-proof housing side by side, the other pressure-sensitive resistor is disposed at the top portions or the bottom portions of the two pressure-sensitive resistors which are aslant arranged side by side, the three pressure-sensitive resistors are connected through a wiring board, and gaps are reserved among the three pressure-sensitive resistors. According to the utility model, under the condition that the performance of a conventional protector is ensured, the size of the protector is greatly reduced so as to be adaptive to arrangement of different circuits. A seal base plate is fixed on an aluminum casing through clamping connection, thermal sealing or glue sealing, such that the explosion-proof effect of the protector can be further improved. Besides, an outer sealing casing is also arranged outside the flame-retardant explosion-proof housing so that the explosion-proof effect of the protector can be further improved.
