The invention discloses a switch movable contact group and a movable and static contact device, which comprise symmetrical frame structure herringbone swing pieces, the end part of the vertical upper section of each herringbone swing piece is hinged with a movable contact unit through a first connecting shaft, and the center of a transition area is used as the rotating axis of each herringbone swing piece; the corresponding first rotating shaft is positioned and mounted at the lower part of the static contact seat; the rotating axis of the swing head and the rotating axis of the herringbone swing piece are located on the symmetrical faces of the pair of static contact units. In the zero position state, the adapter fixed to the top end of the swing head is symmetrically located in an opening area formed by the left fork section and the right fork section of the herringbone swing piece, and gaps exist between the adapter and the left fork section and between the adapter and the right fork section. The driving mechanism of the movable contact group of the switch is simple in structure and does not involve complex multi-stage transmission of a connecting rod, a sliding block and the like; and when the driving direction is changed, the top end adapter firstly experiences a section of idle stroke in the process of swinging leftwards/rightwards along with the swinging head, so that the reliability in a complex working environment is further improved.

    本申请公开了一种转辙机动接点组及动静接点装置,包括对称的框架结构人字形摆动件,人字形摆动件的竖向上段的端部通过第一连接轴与动接点单元铰接,过渡区域的中心作为人字形摆动件的转动轴心,相应的第一转轴定位安装于静接点座的下部;摆动头的转动轴心、人字形摆动件的转动轴心位于一对静接点单元的对称面上;在零位状态时,固定于摆动头顶端的适配件对称地处于人字形摆动件左叉段与右叉段形成的开口区域、但与左叉段和右叉段存在间隙。该转辙机动接点组的驱动机构结构简明,不涉及复杂的连杆、滑动块等多级传动;而且在驱动方向改变时,顶端适配件随摆动头向左/向右摆动的过程中首先会经历一段空程,进一步提高了复杂工作环境下的可靠性。
