Circuit breaker exhaust structure

The utility model relates to an exhaust structure of a circuit breaker, which relates to the field of circuit breakers and comprises a middle shell and a base, the middle shell is of an integral structure, and both the middle shell and the base are provided with exhaust ports. According to the utility model, the strength of the shell is not reduced, the breaking capacity is improved, the aesthetic feeling of the appearance is improved, the situation that charged metal particles are sprayed out from the upper end of the side surface of the circuit breaker to cause breakdown short circuit and harm personal safety is avoided, the flashover distance of a product can be shortened, and electric arcs can be effectively separated to prevent electric arc reignition; therefore, the use safety of the circuit breaker is ensured. 本实用新型涉及一种断路器排气结构，涉及断路器的领域，其包括中壳和基座，中壳为整体式结构，中壳和基座均设有排气口。本实用新型不会降低壳体的强度，不仅提高分断能力还提升了外形的美感，避免断路器侧面上端喷出的带电金属粒子，导致击穿短路，危害人身安全，也可以缩短产品的飞弧距离，还可以有效分隔电弧阻止电弧重燃，从而保证断路器的使用安全性。
