    • PROBLEM TO BE SOLVED: To provide a mechanism section of a circuit breaker whose assembly workability is significantly improved than ever before.SOLUTION: In a mechanism section of a circuit breaker, a cradle 11 is pivotally supported in a frame 10 and a reverse spring 25 is provided in a stretched manner between a link pin 18, which is arranged at the lower part of a link plate 12 pivotally attached to the cradle 11, and a handle lever 14 so that the handle lever 14 is swingably attached to the frame 10. In oder to assemble the mechanism section easily, a handle lever temporary holding position for hanging a hook 26 located at the top of the reverse spring 25 on the handle lever 14 is provided at a position where the reverse spring 25 becomes shorter than in a state where the handle lever 14 is attached to the frame 10. The handle lever 14, having the reverse spring 25 hung thereon, is pulled and engaged at a prescribed position of the frame 10.
    • 要解决的问题:提供一种断路器的机构部分,其组装可操作性比以前显着改善。 解决方案:在断路器的机构部分中,支架11枢转地支撑在框架10中,并且反向弹簧25以拉伸的方式设置在连接销18之间,该连杆销18布置在 枢轴连接到支架11的连杆板12和手柄杆14,使得手柄杆14可摆动地附接到框架10.为了容易地组装机构部分,手柄杆临时保持位置用于悬挂位于 在手柄杆14上的反向弹簧25的顶部设置在反向弹簧25变得比手柄杆14附接到框架10的状态下更短的位置。手柄杆14具有反向弹簧 25挂在上面,被拉动并接合在框架10的规定位置。版权所有(C)2012,JPO&INPIT
