Technical Problem
[0003]然而，现有技术中底盖与断路器本体的连接方式存在明显缺陷，主要表现为结构复杂和操作效率低下
Benefits of technology
[0024]胀紧斜面在底盖转动安装过程中产生向内的胀紧力，临时固定底盖，防止脱落，提高装配效率和安全性；斜面设计简化操作。作为一种优选方式，胀紧斜面为15-30度斜坡，安装凸边内壁覆高摩擦材料；工作原理是转动时凸边沿斜面滑动，斜面角度引导凸边内缩，形成自锁。另一种方式是斜面集成弹簧片，在接触时弹性变形施加压力；该结构通过机械胀紧提供可靠预固定，减少装配失误率。

Abstract
A bottom cover for a circuit breaker, comprising a circuit breaker body matched therewith, a detachable connection being formed between the bottom cover and the circuit breaker body, a penetrating area for placing a connecting copper bar being formed between the bottom cover and the circuit breaker body, a plurality of mounting plates being arranged on an end surface of the bottom cover towards the circuit breaker body, an embedding groove being arranged on the circuit breaker body corresponding to a positioning strip, the mounting plate and the embedding groove being matched to form a fixation between the bottom cover and the circuit breaker body, and the mounting plate and the embedding groove being matched to divide the penetrating area into a plurality of independent placing slots for placing the connecting copper bar. The utility model has the beneficial effects that: through the matching structure of the mounting plate and the embedding groove, not only the detachable fixation between the bottom cover and the circuit breaker body is realized, but also the penetrating area is divided into a plurality of independent placing slots, the creeping phenomenon caused by arc propagation between different connecting copper bars is effectively prevented, and the electrical safety is improved.
