AI Technical Summary
Technical Problem
The sealing plugs of existing miniature circuit breakers are inconvenient to install and remove in confined spaces, affecting the sealing effect.
Method used
A drive rod is used to press the rubber pad tightly against the housing, and a spring is used to maintain the seal. The clamp is connected to the drive rod by an external thread, and the rubber pad is stably fixed by the support ring and the cross groove to prevent it from falling off.
Benefits of technology
The system enables convenient installation and removal of the sealing plug in confined spaces, ensuring a good seal, preventing the rubber gasket from falling off, and improving both sealing performance and ease of operation.

Abstract
This utility model discloses a miniature circuit breaker, including a housing with terminals inside. The terminals include a bracket, a clamp, and a drive rod. One end of the drive rod passes through the bracket and connects to the clamp. A wrench passes through a slot in the housing, causing the drive rod to rotate, which in turn causes the clamp to slide along the bracket. A rubber pad is also provided at the end of the drive rod away from the clamp, and a spring causes the drive rod to press the rubber pad firmly against the housing. When a tool passes through the slot and contacts the drive rod, it causes the drive rod to rotate, thus moving the clamp and releasing the wire. Throughout this process, the spring continuously compresses the rubber pad, preventing it from falling off and ensuring a seal between the rubber pad and the slot. The rubber pad does not need to be removed during wire connection or disconnection, effectively solving the problem of inconvenient installation of rubber pads in confined spaces.
