The invention provides a shifting contactor of a point switch, relates to the technical field of railway turnout point switches, and solves the technical problem of poor sealing and waterproof performance of an existing point switch shifting contactor. The shifting contactor comprises a switch base, a switch box, a first binding post, a second binding post, a reset button, a cover cap, an embeddedpart, a contact and a sealing isolation assembly, the sealing isolation assembly comprises a plurality of sealing rings, and the plurality of sealing rings are respectively arranged in a plurality ofgaps where the shifting contactor is communicated with the external environment, so that the shifting contactor forms a full-closed state. The plurality of sealing rings seal theplurality of gaps, communicated with the external environment, of adisplacement contactor,wet steam and water are prevented from entering the shifting contactor, the insulation performance of the shifting contactor is improved, the problems that due to poor insulation, electrical characteristic indexes of a point switch are affected, signal equipment line mixing faults are caused, point switch equipment representationfaults are caused, and normal operation and driving safety of a train are affected are solved, and therefore the safety and reliability of rail operation are improved.
本发明提供了一种转辙机移位接触器,涉及铁路道岔转辙机技术领域,解决了现有转辙机移位接触器密封防水性能不佳的技术问题。该移位接触器包括开关座、开关盒、第一接线柱、第二接线柱、复位按钮、盖帽、嵌装件、触头和密封隔离组件,密封隔离组件包括多个密封圈,多个密封圈分别设置于移位接触器与外界环境连通的多个缝隙内,使移位接触器形成全封闭状态。多个密封圈封闭了移位接触器与外界环境连通的多个缝隙,防止湿汽和水进入移位接触器内,提高了移位接触器的绝缘性能,避免绝缘不良而影响转辙机电气特性指标,导致信号设备混线故障,引起转辙设备表示故障,影响列车的正常运营和行车安全的问题,从而提高了轨道运行的安全性和可靠性。
