一种配电设备用断路器

Abstract

本实用新型公开了一种配电设备用断路器，涉及断路器技术领域。本实用新型包括外壳，所述外壳内部开设有若干个接线槽，还包括防护机构，所述防护机构数量为若干组，若干组所述防护机构所包含零部件相同，所述防护机构安装在外壳上。本实用新型通过设置紧固组件，具体是转动内螺纹管带动外螺纹管向接线槽内部滑动，外螺纹管下移过程中，夹板的弧形面与接线槽边缘相互作用，使弹性设置的夹板向内侧收缩，对穿入接线槽内的线缆形成夹紧固定，弹性垫增加与线缆的摩擦力并减少夹持损伤，该结构无需借助多种专用工具，仅通过转动内螺纹管即可完成线缆固定，降低后续线缆使用的过程中出现松动脱离的情况，降低安全事故的发生。
