Description

高压直流继电器防水平偏转机构 技术领域
[0001] 本发明涉及一种高压直流继电器， 具体涉及一种用于防止高压直流继电器内动 簧片偏转的高压直流继电器防水平偏转机构。
背景技术
[0002] 高压直流继电器中， 动铁芯会带动推动杆上下移动， 以使固定在推动杆上端动 簧片上的动触点与静触点接触或分离。 现有技术中， 作为连接动铁芯和动簧片 的推动杆仅在轴向方向具有导向， 而推动杆圆周方向上并没有限位， 因此， 推 动杆在上下运动过程中可能会发生圆周方向上转动， 从而造成与推动杆固定的 动簧片发生水平方向上的偏转， 进而造成动触点与静触点不能精确对准， 影响 了继电器的可靠性。
技术问题
[0003] 本发明的目的是提供一种可避免动簧片水平偏转、 能保证继电器动静触点精准 接触， 可提高继电器可靠性的高压直流继电器防水平偏转机构。
问题的解决方案
技术解决方案

[0005] 本发明通过在动簧片设有动触点的左右两端分别设置左返力弹簧和右返力弹簧 ， 一方面可提供动静触点的分断力， 由于左返力弹簧和右返力弹簧是直接作用 在动簧片上， 故在动静触点需要分离吋可使动触点与静触点快速分离， 继电器 响应迅速； 另外， 由于动簧片两端分别被拉紧作用在定位板上， 因此， 左返力 弹簧和右返力弹簧始终具有一个阻止动簧片水平转动的作用力， 从而保证动触 点和静触点的精确对准， 保证动静触点能可靠精准地接触， 避免动簧片与其它 零部件接触导致故障的发生。 其中， 定位板由绝缘材质制成， 比如塑料材质。
[0006] 作为优选， 所述定位板对应于动簧片的左端下方位置和对应于动簧片的右端下 方位置各形成有一个向上延伸的弹簧固定板， 所述弹簧固定板上形成有弹簧下 固定孔， 所述弹簧下固定孔的内壁上搭配有保护圈。 其中， 保护圈可为铁圈等 具有一定刚性的材质制成， 以避免左返力弹簧和右返力弹簧将定位板的弹簧固 定板拉断， 以保证继电器的可靠性。
[0007] 作为优选， 所述左返力弹簧的轴线及右返力弹簧的轴线均与推动杆的轴线平行 ， 左返力弹簧与动簧片的连接点及右返力弹簧与动簧片的连接点均位于两个动 触点之间的位置并靠近动触点的内侧。 左返力弹簧的轴线及右返力弹簧的轴线 均与推动杆的轴线平行可进一步提高动簧片水平方向的稳定性。
