具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
下面参考图1-图4详细描述根据本申请实施例的继电器100。
如图1和图2所示，根据本申请实施例的继电器100可以包括：线圈1、铁芯2、传动轴3、接线柱4、动触板5、永磁铁6和磁敏开关7。
线圈1设置在铁芯2的外侧，即铁芯2设置在线圈1的内侧，而且铁芯2在线圈1通电后轴向运动。具体地，铁芯2能够在线圈1的驱动下沿上下方向运动，其中轴向即上下方向。
铁芯2固定连接在传动轴3的下端，而且传动轴3可以在铁芯2的带动下做上下方向的运动，例如，在线圈1通电后，传动轴3可以从下向上移动。而且通过将铁芯2固定在传动轴3的下端，可以使得传动轴3和铁芯2配合适宜，可以使得传动轴3长度适宜，从而可以保证继电器100的结构可靠性。
接线柱4一般为两个(正极/负极)，即第一接线柱和第二接线柱，图1和图2所示的两个接线柱4为第一接线柱和第二接线柱。
如图1和图2所示，动触板5设置在传动轴3的上端，而且动触板5能够在传动轴3的驱动下与接线柱4接触或者分离。具体地，动触板5能够在传动轴3的带动下在第一位置和第二位置之间运动；动触板5位于第一位置时，第一接线柱和第二接线柱通过动触板5导通，动触板5离开第一位置时，第一接线柱和第二接线柱断开电连接。
此处第一位置为能够使得两个接线柱4导通的位置，即动触板5能够运动到的最顶端；而第二位置为两个接线柱断开电连接的位置，此时，动触板5远离接线柱4，一般情况下可以认为第二位置为动触板5能够运动的最低端。
需要说明的是，只有当动触板5位于第一位置时，第一接线柱和第二接线柱才会导通，而当动触板5离开第一位置，向第二位置运动的整个过程中，第一接线柱和第二接线柱是不导通的。
如图1和图2所示，动触板5设置在传动轴3的上端，而且动触板5能够在传动轴3的驱动下与接线柱4接触或者分离。例如，在线圈1通电后，动触板5可以从下向上移动，直至与接线柱4导通，这样继电器100的主触点可以从断开切换为导通状态。又如，在线圈1断电后，在传动轴3和铁芯2的驱动下动触板5与接线柱4分离，这样继电器100的主触点可以从导通切换为断开状态。
如图1和图2所示，永磁铁6设置在动触板5上，永磁铁6能够在动触板5的带动下沿上下方向运动。磁敏开关7位于在永磁铁6的一侧，该一侧可以为永磁铁6的上下前后左右侧中的任意一侧。磁敏开关7在永磁铁6由下至上的运动过程中由第一状态切换至第二状态，磁敏开关7在永磁铁6由上至下的运动过程中由第二状态切换至第一状态。也就 是说，永磁铁6在上下方向上的运动可以改变磁敏开关7的通断状态，而且运动方向的不同可以导致磁敏开关7的状态变化不同。需要说明的是，磁敏开关7状态的切换速度和位置可以由线圈1通电的电流大小以及永磁铁6等因素决定，在此不做限定。可选地，磁敏开关7可以为干簧管。
需要说明的是，在继电器100工作时，实际上动触板5的动作非常快，一个行程的时间非常短；因此，只要永磁铁6在运动过程中，磁敏开关7发生切换，就能够起到辅助触点的作用。因为时间非常短，所以运动过程中切换和运动到顶端切换，实际上区别不大，不影响其功能。
其中，具体地，动触板5位于第一位置时，磁敏开关7为第一状态；动触板5离开第一位置时，磁敏开关7为第二状态。
其中，可选地，第一状态可以为导通状态，第二状态可以为断开状态。也就是说，磁敏开关7在永磁铁6由下至上的运动过程中由导通状态变为断开状态，磁敏开关7在永磁铁6由上至下的运动过程中由断开状态切换至导通状态。
另一种可选地，第一状态可以为断开状态，第二状态可以为导通状态。也就是说，磁敏开关7在永磁铁6由下至上的运动过程中由断开状态切换至导通状态，磁敏开关7在永磁铁6由上至下的运动过程中由导通状态切换至断开状态。
需要强调的是，本申请是通过改变永磁铁6和磁敏开关7之间的距离，通过永磁铁6磁场对磁敏开关7带来的影响，驱动磁敏开关7的通断。具体地，当永磁铁6与磁敏开关7比较接近时，可驱动磁敏开关7的动作；而当永磁铁6与磁敏开关7较远时，不对其造成影响。
具体磁感应原理如下：磁敏开关7和永磁铁6的间距，决定了磁敏开关7的动作。当磁敏开关7位于永磁铁6的左侧时(如图1所示)，动触板5位于第一位置(即第一接线柱和第二接线柱导通的位置)时，永磁铁6和磁敏开关7在水平方向上正对设置(这里说的“正对设置”是指，永磁铁6和磁敏开关7位于同一个水平线上，并且两者之间的间距是整个永磁铁6运动过程中最小的位置)，永磁铁6和磁敏开关7的间距最小，磁敏开关7处于第一状态；而当动触板5离开第一位置时，由于永磁铁6和磁敏开关7的间距变大，磁敏开关7会变为第二状态。这里虽然说的是“位于”第一位置和“离开”第一位置，但对于动触板5来说，是固定的位置。而对于永磁铁6来说，由于磁场本身的特性，磁敏开关7不可能完全的当永磁铁6处于一个位置时导通，而当永磁铁6离开一个位置时就能立马断开，因为磁场是一个渐变的过程。因此，在本申请中，实际上“位于”和“离开”第一位置，都有一个用于磁场影响而存在的合理误差，这个误差可能与磁场本身的强度有关，在本申请中，也应 当将该合理误差包含在内。
由此，根据本申请实施例的继电器100，采用磁感应原理，通过改变永磁铁6的位置，可以改变相对应的磁敏开关7的导通断开状态，在监测继电器100通断状态的同时，使继电器100的高压部分与低压部分完全分离，可以有效避免系统高压电路窜入低压电路，从而可以提高应用系统的安全性。另外，如此设置的继电器100结构简单，线圈1的绕制简单，永磁铁6和磁敏开关7占用空间小，从而可以有效降低继电器100的体积。还有，如此布置的继电器100还可以减轻电磁激励回路漏磁现象。
可选地，动触板5上设置有用于与接线柱4接触或分离的动触点。这样动触点能够与接线柱4接触可靠，从而可以提高继电器100的工作可靠性。
根据本申请的一个具体实施例，如图1和图2所示，永磁铁6可以设置在动触板5的边缘处。这样永磁铁6的位置布置适宜，从而可以有利于磁敏开关7的布置，可以降低磁敏开关7的布置难度，进而可以提高继电器100的结构可靠性。
可选地，如图1和图2所示，永磁铁6设置在动触板5的下表面上，这样可以避免永磁铁6和接线柱4之间的互相干涉，从而可以使得动触板5结构布置合理，进而可以提高继电器100的结构可靠性。
可选地，如图1和图2所示，继电器100还可以包括：壳体9，动触板5、永磁铁6设置在壳体9内，磁敏开关7设置在壳体9的侧壁上，例如，如图4所示，磁敏开关7可以设置在壳体9的外侧壁上。当然，磁敏开关7还可以设置在壳体9的内侧壁上，或者，磁敏开关7还可以与壳体9的侧壁为一体成型结构。由此，磁敏开关7位置布置适宜，能够有效感知永磁铁6的磁场变化。
具体地，如图3所示，动触板5位于第一位置时，永磁铁6和磁敏开关7在水平方向上正对设置。这样可以提高磁敏开关7感知永磁铁6的磁场变化的精准性，从而可以使得磁敏开关7状态切换准确且迅速。
可选地，永磁铁6与动触板5可以粘接固定。这样永磁铁6和动触板5固定方式简单，而且固定可靠，效率高。
可选地，磁敏开关7的两端引出有第一端和第二端。其中，在具体使用过程中，继电器100可以通过磁敏开关7的第一端和第二端将磁敏开关7接入继电器100的监测回路。
根据本申请的一个可选实施例，如图1和图2所示，继电器100还可以包括：限位件10，限位件10套设在传动轴3上，而且限位件10位于铁芯2的上下运动方向上，其中铁芯2和传动轴3相对限位件10能够运动。例如，限位件10可以设置在铁芯2的上方，在线圈1通电后，动触板5和接线柱4导通，限位件10和铁芯2可以相互止挡，从而限位件 10可以实现其限位作用。或者可以这样说，在线圈1通电后，限位件10止挡铁芯2，动触板5和接线柱4导通。
进一步地，如图1和图2所示，继电器100还可以包括：复位件11，复位件11止抵在限位件10和铁芯2之间以驱动铁芯2复位。可以理解的是，复位件11具有促使铁芯2复位的效果。在线圈1通电时，限位件10可以限制铁芯2的位置，在线圈1断电后，复位件11可以推动铁芯2向下移动，从而可以促使铁芯2回复到初始位置，这样动触板5和接线柱4断开，永磁铁6远离磁敏开关7，磁敏开关7断开。
具体地，如图1和图2所示，复位件11可以为弹簧，弹簧套设在传动轴3上，限位件10内设置有容纳槽，弹簧的一部分容纳在容纳槽内。通过设置容纳槽，可以提高弹簧与限位件10之间的配合可靠性，而且可以有效节省继电器100的内部空间。
可选地，限位件10可以为柱状，而且限位件10的外径与铁芯2外径相同，限位件10朝向铁芯2的表面为平面。这样可以使得限位件10和铁芯2相匹配，而且这样限位件10可以更好地止挡铁芯2的上表面，从而可以提高限位件10的限位效果。
