    • A link assembly is for an electrical switching apparatus, such as a circuit breaker. The circuit breaker includes a housing, separable contacts enclosed by the housing, and an operating mechanism for opening and closing the separable contacts. The operating mechanism includes a movable contact arm. The separable contacts comprise a stationary contact and a movable contact. The movable contact is disposed on the movable contact arm. The link assembly includes a pivot assembly pivotably coupled to the movable contact arm, a link element pivotably coupled to the pivot assembly, and a biasing element, such as a spring. A first end of the spring is coupled to the link element, and a second end of the spring is coupled to the circuit breaker housing.
    • 连接组件用于诸如断路器之类的电气开关装置。 断路器包括壳体,由壳体包围的可分离触点,以及用于打开和关闭可分离触点的操作机构。 操作机构包括可动接触臂。 可分离触点包括固定触点和可动触点。 可动触点设置在可动触点臂上。 连杆组件包括可枢转地联接到可动接触臂的枢轴组件,可枢转地联接到枢转组件的连接元件以及诸如弹簧的偏置元件。 弹簧的第一端联接到连杆元件,弹簧的第二端连接到断路器壳体。
