Abstract
The invention relates to a connecting lever box, connecting lever box connecting and assembling structure and breaker. The connecting lever box includes a mechanism mounting part used for mounting and supporting a mechanism core body, and the mechanism mounting part is used for forming a part of a mechanism box body. A part of the mechanism box body of a breaker operating mechanism is integrated on the connecting lever box, so that the mechanism core body can be directly mounted on the connecting lever box, and the connecting lever box bears weight of the mechanism core body and operating force impact, and since an existing connecting lever box itself has relatively high load-bearing and anti-impact capabilities during machining, use of a mechanism box body with a complicated structure and relatively high cost is avoided, compared with a traditional structure in which a mechanism core body is mounted in a mechanism box body first and is then in butt joint with a connecting lever box, the connection structure of the breaker operating mechanism is simplified, and production and assembling cost is reduced.
