具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
结合图1和图2，根据本公开一个实施例的继电器100，包括：机壳1、底板2以及驱动装置4。
机壳1上设有相互绝缘的两个静触点11。底板2在导通位置和断开位置之间可移动地设在机壳1内。如图2所示，在导通位置，底板2与两个静触点11相接触使两个静触点11相互导通。如图1，在断开位置，底板2与两个静触点11分离使两个静触点11相互断开。
驱动装置4与底板2相连以驱动底板2在导通位置和断开位置之间切换。
底板2上设有与两个静触点11对应的两个接触部21，且两个接触部21相互间隔开并绝缘。底板2内形成有空腔201，空腔201内设有保险丝3，保险丝3与两个接触部21相连，通过保险丝3实现两个接触部21之间的电连接。其中，底板2位于导通位置时，两个接触部21与两个静触点11对应地接触，使得两个静触点11电连接。也就是说通过保险丝3将两个接触部21电连接，由于两个接触部21与两个静触点11对应地接触，可以通过保险丝3将两个静触点11电连接。底板2位于断开位置时，两个接触部21与两个静触点11分离，于是两个静触点11断开。
如图5，在本公开的一些实施例中，所述底板2包括保险丝安装部22和设置在保险丝安装部22两端的两个接触部21。所述两个接触部21与两个静触点11对应。所述保险丝安装部22内形成有空腔201，所述空腔201内设有保险丝3，两个接触部21通过所述保险丝3电导通。所述底板2设在所述机壳1内，并可在导通位置和断开位置之间切换，所述 底板2在所述导通位置时，两个所述接触部21与两个所述静触点11接触以使两个静触点11电导通。所述底板2在所述断开位置时，两个所述接触部21与两个所述静触点11分离使两个所述静触点11断开电导通。
一些实施例中，所述两个接触部21为设置在保险丝安装部22两端上表面的两个动触点。即两个接触部21设置在保险丝安装部22的上表面，而不是添加在保险丝安装部22左右两端，直接将设置在保险丝安装部22上的两个动触点作为两个接触部21。
进一步，为了更好的实现两个接触部21之间的绝缘，可以将保险丝安装部22设置成绝缘体。
在继电器100的使用过程中，如果出现电流过载或短路等问题时，保险丝3断开，从而使两个静触点11之间的电连接断开，使继电器100处于断开状态，从而断开电路。
根据本公开实施例的继电器100，由于在底板2中设置了保险丝3，通过保险丝3实现了过载保护以及短路保护，以提高具有该继电器100的电路系统的安全性，避免由于过流或短路引起的火灾等。
本公开使用保险丝3进行过载保护，有效的避免了电流过载或短路造成的危险。
本公开中将保险丝3集成在底板2内，方便保险丝3的更换以及继电器100的维护，便于继电器100以及具有该继电器100的电路系统的使用和维护。
结合图4和图5，在本公开的一些实施例中，保险丝安装部22内形成两端敞开的空腔，两个接触部21设在保险丝安装部22的两端，且两个接触部21封闭保险丝安装部22的两端。保险丝3设在保险丝安装部22内并且保险丝3两端分别与两个接触部21相连，两个接触部21通过保险丝安装部22隔开并电隔离，以实现两个接触部21通过保险丝安装部22绝缘。保险丝3的两端分别与两个接触部21相连，通过保险丝3实现两个接触部21之间的电导通。
也就是说，两个接触部21之间通过保险丝3实现电导通，当保险丝3熔断后，就能够断开两个接触部21之间的电导通。
两个所述接触部21均安装在保险丝安装部22上，且两个接触部21之间相互绝缘。可以在保险丝安装部22表面涂覆绝缘层；也可以在两个接触部21与保险丝安装部22之间设置绝缘件。
可以将保险丝安装部22设置成由绝缘材料制成，例如，可以将保险丝安装部22设置成中空的陶瓷腔体。
进一步地，参照图3和图4，保险丝安装部22设置成两端敞开的中空腔体，将两个接触部21安装在保险丝安装部22的两端，并通过两个接触部21封闭保险丝安装部22的两端，另外，保险丝3可以安装在保险丝安装部22内部，由于保险丝安装部22的两端敞开 并由两个接触部21封闭，因此，可以方便保险丝连接两个接触部21。
两个接触部21分别封闭保险丝安装部22的两端，以在保险丝安装部22内限定出一个封闭的腔。保险丝安装部22内容纳保险丝3，从而对保险丝3起到一定的保护作用，在保险丝3熔断时，避免了熔断的保险丝3散落产生安全隐患，从而提高了继电器100的安全性能。
另外，在本公开的一个实施例中，为了方便静触点与接触部接触，在两个接触部中的至少一个上设置了动触点(未示出)。
结合图4和图5，保险丝安装部22端面的一部分向外凸出形成第一台阶221，每个接触部21上形成有与保险丝安装部22端面上的第一台阶221互补的第二台阶211。每个接触部21与保险丝安装部22形状互补并相互扣合，在将每个接触部21安装在保险丝安装部22上时，可以通过第一台阶221和第二台阶211的配合定位每个接触部21，以方便将两个接触部21安装在保险丝安装部22上，提高两个接触部21的安装效率和稳定性。
需要说明的是，两个表面互补是指：两个表面贴合到一起时，一个表面上设置了凸起，则另外一个表面上对应地设置了缺口。另外，需要说明的是，保险丝安装部22上设置了第一台阶221，则保险丝安装部22上形成有第一缺口，每个接触部21上形成有第二台阶211，则每个接触部21上形成有第二缺口。这是因为，在一个平面上，如果存在凸起部分，则平面上没有凸起的部位必然会形成一个相对于凸起凹陷的部分。
每个接触部21与保险丝安装部22形状互补，是指：保险丝安装部22的端面上设置了第一台阶221，每个接触部21的端面上与第一台阶221配合的地方设置了第一缺口，第一台阶221和第一缺口的形状相同。每个接触部21的端面上形成有第二台阶211，保险丝安装部22的端面上与第二台阶211配合的地方设置了第二缺口。在装配时，第一台阶221与第一缺口配合，第二台阶211与第二缺口配合。从而使得保险丝安装部22的一个端面与每个接触部21的一端端面贴合到一起，实现第一台阶221和第一缺口的扣合。
进一步地，参照图5，每个接触部21的上表面高于保险丝安装部22的上表面。在底板2位于导通位置时，由于接触部21的上表面高于保险丝安装部22的上表面，因此可以便于接触部21与静触点11对接，从而使得接触部21与静触点11稳定地对接，提高继电器的稳定性。
两个接触部21与保险丝安装部22焊接，使得两个接触部21与保险丝安装部22之间连接稳定，连接的强度高，从而提高继电器的稳定性。
另外，可以在保险丝安装部22的两端设置金属层，将两个接触部21安装在保险丝安装部22上时，两个接触部21可以与保险丝安装部22稳定的焊接。
为了进一步地提高继电器100的灭弧效果，本公开在底板2的空腔内填充有石英砂(未 示出)。通过石英砂灭弧，避免了由于产生电弧导致的安全隐患，减少了保险丝3熔断时拉弧时间长对产品安全造成的影响。
有利地，参照图4，底板2上还设有注砂孔202以及封闭件(图中未示出)，通过封闭件可以封闭或打开注砂孔202，且底板2的空腔由石英砂填充。
在本公开的而一些实施例中，继电器100还包括沿周向设置的磁铁(未示出)。在磁铁的磁场作用下，将电弧拉长，此时通过灭弧栅将电弧分割为段，从而通过磁铁起到灭弧的作用。
在本公开的一些实施例中，参照图1至图5，保险丝安装部22的下面设有连接部222，驱动装置4与连接部222相连。
进一步地，如图5并结合图1，连接部222呈两端与前述的保险丝安装部22相连且中部下凸的倒梯形，连接部222的中部与保险丝安装部22隔开，驱动装置4与所述连接部的中部相连。通过设置连接部22连接驱动装置4，使得继电器的结构简单，方便继电器的制作，减少制作时间。
结合图1和图3，驱动装置4包括推动杆44和缓冲弹簧47，推动杆44的上端与连接部222相连且下端向下伸出机壳1。推动杆44的上端穿过连接部222并连接有卡簧48和垫片49，卡簧48卡在推动杆44上，垫片49位于卡簧48和连接部222之间。缓冲弹簧47套在推动杆44的外侧，缓冲弹簧47的上端抵在连接部222上，且缓冲弹簧47的下端抵在推动杆44或机壳1的底壁上。通过缓冲弹簧47和卡簧48等的配合，实现的对板2的缓冲。在继电器的导通和断开过程中，通过缓冲可以避免两个接触部21与两个静触点11的刚性接触，提高继电器的稳定性，并降低继电器的噪音。
进一步地，如图1所示，驱动装置4连接在机壳1底部，驱动装置4包括：套筒41、限位柱42、铁芯43和复位弹簧45。
套筒41上端与机壳1相连，限位柱42设在套筒41内的上部并与机壳1相连，铁芯43设在套筒41内的下部并沿上下可移动，推动杆44的一端与铁芯43相连且另一端与底板2相连，复位弹簧45套在推动杆44外侧且两端分别抵压铁芯43和限位柱42。由此，易于通过驱动装置4实现对继电器100通断的控制，从而可以在一定程度上提高继电器100的使用性能。
其中，在图1和图2的示例中，复位弹簧45的下端抵压铁芯43，且复位弹簧45的上端抵压限位柱42。由此，在复位弹簧45的作用下，使得驱动装置4的动作更加平稳且易于实现对继电器100通断的控制。
结合图1至图3，在本公开的一些实施例中，底板2上设有过孔，推动杆44的上端(例如，图1中推动杆44的上端)可以穿过过孔，推动杆44穿过过孔的端部设有卡簧48和垫 圈49，垫圈49能够减小卡簧48的受力且可防止卡簧48脱落，这样可以进一步提高继电器100的工作稳定性。推动杆44的外套设有缓冲弹簧47，缓冲弹簧47可以用于常推动推动杆44使底板2压紧卡簧48。由此，可使推动杆44的动作更加平缓，还可以改善继电器100的动作准确性。
其中，缓冲弹簧47的一端与底板2相连，且缓冲弹簧47的另一端与推动杆44和外壳中的一个相连。
也就是说，结合图1和图2，缓冲弹簧47的第一端与底板2相连(例如，图1中缓冲弹簧47的上端)，缓冲弹簧47的第二端(例如，图1中缓冲弹簧47的下端)与推动杆44相连。也可以是缓冲弹簧47的第一端与底板2相连(例如，图1中缓冲弹簧47的上端)，缓冲弹簧47的第二端(例如，图1中缓冲弹簧47的下端)与机壳1的底壁相连。当然还可以是缓冲弹簧47的上端连接机壳1而下端连接底板2，此时缓冲弹簧应当常处于拉伸的状态。这样可以提高继电器100的动作平稳性，更好地满足用户的需求。
如图1，在本公开的一些实施例中，机壳1包括：陶瓷壳体101，托板102，连接台103。其中，陶瓷壳体101的底部敞开，托板102设在陶瓷壳体101下面以封闭陶瓷壳体101底部，连接台103分别与陶瓷壳体101和托板102相连。通过陶瓷壳体101和托板102的配合，以避免灰尘等进入到机壳1内，同时可以提高用电安全。而且将机壳1分解为陶瓷壳体101、托板102和连接台103，可以方便底板2、驱动装置4等元件的安装。
连接台103设在陶瓷壳体101和托板102之间，且连接台103呈沿陶瓷壳体101的周向延伸的环形，连接台103分别与陶瓷壳体101和托板102相连，通过连接台103将陶瓷壳体101和托板102连接在一起，并通过连接台103实现陶瓷壳体101与托板102之间的密封。
陶瓷具有较好地强度、高的化学稳定性和热稳定性，而且还是电的不良导体。本公开中设置陶瓷壳体101。提高了机壳1的绝缘性能，以减少安全隐患。而且通过陶瓷壳体101实现良好的灭弧效果。
当然，在本公开其他实施例中，机壳1可以为其他的绝缘材质，本公开对机壳1的具体材质不作限定，实际应用中可以适应选择。
进一步地，机壳1内填充有氢气或氦气。通过氢气和氦气，可以形成灭弧气体层，在继电器100开关过程中，通过氢气和氦气快速地灭弧，降低安全隐患。
在充满氢气或氮气的密闭空间里，当保险丝3正常工作产生电弧时，在气体(氢气或氮气)的冷却作用下，能实现快速灭弧，从而可以进一步提高继电器100的使用安全性。
根据本公开实施例的继电器100，既有电路的过流保护作用，又能够实现断路器的功能。其中短路保护结构由接触部21、陶瓷腔(即保险丝安装部22)、保险丝组成。如图1 所示，陶瓷腔将接触部21与推动杆44隔离以将高低压隔离，保险丝起到过载保护的作用，垫圈能够减小卡簧的受力，防止其脱落。
根据本公开实施例的继电器100可如下进行装配，先将保险丝置于陶瓷腔内，再将两个接触部21与陶瓷腔两端的台阶安装好，并将两个接触部21焊接至陶瓷腔。往陶瓷腔孔内注石英砂，用止付螺丝锁紧。然后将推动杆装配缓冲弹簧穿过陶瓷腔的安装孔，最后装配垫圈，再用卡簧固定。
将上述组件组装后，再安装驱动装置4。推动杆依次装上托板102、限位柱42、复位弹簧45，铁芯43用激光焊接或者螺纹的方式与推动杆固定。如图1中所示，继电器为断开状态，当驱动装置4开始工作后，两个接触部21和两个静触点11接触，切换到为图2所示的导通状态。导通状态下，负载电流通过保险丝，当负载电流过高或电路发生短路时，保险丝熔断，以起到保护作用。同时继电器100的外置磁铁，腔体内的氢气以及陶瓷腔内的石英砂共同作用，能够迅速灭弧，有效增长产品寿命。另外，在导通状态下，陶瓷腔将推动杆与高压负载端隔离，进而将高低压绝缘，避免低压端元器件的损坏及击穿现象的发生，从而提升了产品的品质及安全性。
本公开使用保险丝3进行过载保护，有效的避免了电流过载或短路造成的危险。同时继电器100外置的磁铁，腔体内的氢气以及陶瓷腔内的石英砂的共同作用下，减少了保险丝3熔断时，拉弧时间长对产品安全造成的影响，两个静触点11同时作用，进而提高了产品的熔断的准确性以及使用的安全性。相比而言，本公开将保险丝3与继电器100相结合，节约了整体使用空间以及成本，将继电器100的灭弧机构使用到保险丝3上能够有效提升产品的品质及安全性。
本公开使用保险丝进行过载保护，其他形式的保护措施也在本专利范围内；本公开所使用到的底板2为陶瓷材料制成，其它非金属材料也在本专利范围内。
