Abstract
The utility model discloses a housing protection structure for an anti-explosion breaker, which relates to a breaker. A housing is fixed to a housing cover through a sealing strip and a bolt in a sealed manner. The outer part of the housing is provided with a sign plate and a name plate; the inner side of the housing is provided with a breaker unit. The breaker unit is provided with a first conductive plate and a second conductive plate which are fixed to a conductive rod through a first screw and the conductive rod is fixed to the housing through a third screw. The outer part of the conductive rod is provided with a first dust prevention cover and a second dust prevention cover; the housing is further provided with a plug and a bayonet; the bayonet is fixed by a second screw and cooperatively functions with the breaker unit. The housing protection structure of the utility model makes the structure of the breaker more compact and more reasonable. The optimization of the outer structure of the housing and the reasonable arrangement for the hinged anti-explosion contact face will not cause an explosive mixture at its adjacent space to explode, therefore making a breaker function safely at some working spots.
