Abstract

The invention relates to a switching-on and switching-off handle mechanism of a plug-in circuit breaker. The switching-on and switching-off handle mechanism comprises a handle rocker arm, a turntable,a first connecting rod, a second connecting rod and a locking piece; the handle rocker arm is connected with the turntable through the first connecting rod; the turntable is connected with an operating mechanism through the second connecting rod; a first long-strip-shaped shaft hole and a first linkage part are arranged on the handle rocker arm; a first rotary shaft penetrates through the first long-strip-shaped shaft hole to enable the handle rocker arm to be hinged to a shell; the locking piece is hinged into the shell through a third rotary shaft and a spring piece and comprises a second linkage part and a boss part; the boss part extends out of the shell; when the handle rocker arm is pulled towards the outer side of the shell, the first linkage part drives the second linkage part tomove, so that the locking piece rotates around the third rotating shaft, and the boss part retracts into the shell. Switching-on and switching-off are controlled through rotation of the handle rockerarm; the locking piece is operated through linear movement; and therefore, the misoperation problem that the circuit breaker is disengaged from a cabinet during switching-off is completely avoided, and meanwhile, installation stability is ensured.

Description

technical field [0001] The invention relates to the field of plug-in circuit breakers, in particular to an opening and closing handle mechanism of a plug-in circuit breaker. Background technique [0002] In recent years, plug-in circuit breakers have become more and more widely used, especially with the rapid development of the 5G industry, the demand for 5G cabinets is increasing, and the plug-in circuit breakers used in conjunction with them have attracted more and more attention from manufacturers. [0003] The Chinese invention application with publication number CN 107993900A discloses a plug-in miniature circuit breaker. The invention application is the most common plug-in circuit breaker on the market. The plug-in circuit breaker adopts a button structure. When the button is pressed, the circuit breaker closes; when the button is pulled out, the circuit breaker opens. At the same time, the invention application provides a locking structure for fixing the cabinet and...
