Description

一种漏电断路器的动触头操作机构 技术领域
本发明涉及一种低压漏电断路器，特别是指漏电断路器上的动触头的操作机构。
 背景技术
漏电断路器应用广泛，主要用于，工业，商业，民用住宅等场所，主要用于短路过载保护和漏电保护。现有产品1P+N产品一般采用加宽产品宽度，即在现有小型断路器的基础上拼装漏电模块或者在现有小型断路器基础结构不变的情况下，在小型断路器的上侧或下侧增加线路板和脱扣机构和漏电电流试验装置来实现，产品宽度一般比较大。或者通过加长产品长度来实现，即在小型断路器的上侧或下侧设置线路板和试验装置脱扣机构，因此必须增加漏电断路器的长度，和现在用户使用的用电设备的增多，配电回路的增多，因此配电箱的宽度必须加大或加长，但房屋的配电箱设计空间一般不容易更改，因此现有的较宽或较长的漏电断路器已经满足不了用户的需要。现在急需一种体积小，分断能力高的漏电断路器来填补国内空白。
而现有漏电断路器由于动触头操作机构都比较复杂，其实现上述的功能需要多个部件共同来完成，所述机构的体积比较庞大，很难实现小型化。
 技术问题
本发明克服现有漏电断路器体积大缺陷，提供能使漏电断路器的长度或宽度比现有技术产品小，更能满足客户需要的新型的漏电断路器的动触头操作机构。
 技术解决方案
实现上述目的，本发明采用如下技术方案，一种漏电断路器的动触头操作机构，其特征在于：包括有动触头、跳扣、动触头支架、锁扣弹簧、锁扣和拉簧，其中动触头固定设置在动触头支架上，动触头支架上设置有长通孔，长通孔内设置有销轴，该销轴的两端设置在断路器的基座和盖上，所述拉簧一端连接在动触头支架上，且与动触头支架的连接点位于长通孔的上方，拉簧的另一端固定连接在断路器的基座上或与基座固定连接的其他部件上，所述跳扣铰接设置在动触头支架的上端，跳扣与断路器的手柄之间通过第一连杆连接，所述锁扣中部通过设置的通孔活动套设在销轴上，锁扣上方延伸设置有可与跳扣抵触配合限制跳扣转动的抵触脚，所述锁扣下方设置有推动脚和复位脚，其中推动脚与断路器的脱扣器推杆对应设置，推杆可推动推动脚转动从而实现锁扣转动，锁扣转动使跳扣与抵触脚之间的抵触解锁，这时动触头支架在拉簧的作用下可实现断路器分闸，所述复位脚的顶端部设置有弹簧座，所述锁扣弹簧一端抵触在弹簧座上，另一端抵触在断路器的基座上或与基座固定连接的其他部件上，锁扣弹簧使推动脚向断路器的脱扣器推杆侧转动。
 有益效果
通过采用上述方案，我们很好的实现漏电断路器的动触头操作机构的小型化，具体表现在，动触头的转动是通过动触头支架与拉簧的配合实现，动触头运动的过程是，在静触头合闸时，锁扣的抵触脚与跳扣抵触配合限制跳扣转动，当漏电断路器发生情况动作时，断路器的脱扣器推杆推动推动脚转动从而实现锁扣转动，锁扣转动使跳扣与抵触脚之间的抵触解锁，这时动触头支架在拉簧的作用下转动实现断路器分闸，同时手柄也是转动到分闸状态；合闸时，转动手柄，这时候第一连杆带动跳扣和动触头支架绕着销轴转动，一直到动触头与静触头接触，这时候手柄继续转动，此时由于动触头与静触头已经接触不会发生位置变化，所以动触头支架只能整个移动，使销轴与长通孔的左侧边接触，这样使动触头和静触头的接触更加紧密，并保证动触头与静触头的良好接触。
本发明的进一步设置是：所述动触头支架下方且位于基座一侧上设置容腔，所述动触头上端卡入容腔实现与动触头支架的固定连接，所述动触头支架的长通孔位于容腔部，所述动触头上端设置有与动触头支架的长通孔对应的动触头长通孔，所述销轴穿过长通孔和动触头长通孔设置，所述复位脚的顶端部还设置有连接孔，该连接孔上连接有第二连杆，第二连杆的另一端上抵触设置有双金属片。
通过采用上述方案，使该产品的结构更加合理，其中动触头和动触头支架之间的连接方便，另外长通孔和动触头长通孔构成销轴的连接通孔，这样使动触头支架与动触头均受到销轴的力，运动比较稳固。
本发明的进一步设置是：所述跳扣上设置有卡台，所述抵触脚上设置有与跳扣卡台抵触配合的抵触肩阶，所述跳扣上设置有供第一连杆连接的连接通孔，所述动触头支架上方且与跳扣的连接通孔对应的位置处设置有弧形槽，所述第一连杆连接在跳扣上后其穿出端置于弧形槽内，并可在弧形槽内滑移。
通过采用上述方案，使跳扣与抵触脚之间的抵触配合比较稳固，另外第一连杆在跳扣上后其穿出端置于弧形槽内，并可在弧形槽内滑移，这样对跳扣与动触头支架的转动进行了限定，使两者之间的配合更加合理，当然我们也可以不设置弧形槽以及第一连杆也不穿出设置，两者之间仅仅通过第一连杆的长度进行限定配合。
本发明的最后设置是：所述动触头支架上且位于长通孔上方设置有供拉簧挂设的长孔，所述锁扣的推动脚上且靠近动触头一侧设置有弧形凸起的凸筋，锁扣被断路器的脱扣器推杆推动转动时，推动脚的凸筋顶部与动触头抵触。
通过采用上述方案，其中长孔的设置方便拉簧连接，另外锁扣被断路器的脱扣器推杆推动转动时，推动脚的凸筋顶部与动触头抵触，这样当分断时凸筋顶部与动触头相接触，此时动触头温度较高，因此凸筋顶部与动触头是线接触，接触面积小，锁扣损伤小。

图11是本发明实施例跳扣的立体图。
 本发明的最佳实施方式
如图所示，一种漏电断路器的动触头操作机构，包括有动触头6、跳扣1、动触头支架2、锁扣弹簧3、锁扣4和拉簧5，其中动触头6固定设置在动触头支架2上，动触头支架2上设置有长通孔21，长通孔21内设置有销轴7，该销轴7的两端设置在断路器的基座和盖上，这里销轴7设置在基座或盖上可以是间接设置也可以是直接设置，其主要是指销轴7相对于基座和盖是固定的.关于销轴7与基座和盖的连接方式在现有技术中也是常见的，所述拉簧5一端连接在动触头支架2上，且与动触头支架2的连接点位于长通孔21的上方，这里的上方是指靠近第一连杆8的一侧，这样拉簧5的拉动下动触头支架2会绕着销轴7转动，而销轴7下方的动触头6才可以实现与静触头之间的断开运动，拉簧5的另一端固定连接在断路器的基座上或与基座固定连接的其他部件上，所述跳扣1铰接设置在动触头支架2的上端，跳扣1与断路器的手柄9之间通过第一连杆8连接，关于第一连杆8的作用在普通的断路器中也是有的，所以这里就不对第一连杆8的功能和运动方式做进一步描述了，所述锁扣4中部通过设置的通孔41活动套设在销轴7上，锁扣4上方延伸设置有可与跳扣1抵触配合限制跳扣1转动的抵触脚42，抵触脚42对跳扣1实现抵触锁定或解锁配合，当抵触锁定时动触头支架2的上端就实现固定，这样拉簧5就无法拉动动触头6，所述锁扣5下方设置有推动脚43和复位脚44，其中推动脚43与断路器的脱扣器推杆10对应设置，推杆10可推动推动脚43转动从而实现锁扣4转动，锁扣4转动使跳扣1与抵触脚43之间的抵触解锁，这时动触头支架2在拉簧5的作用下可实现断路器分闸，所述复位脚44的顶端部设置有弹簧座441，所述锁扣弹簧3一端抵触在弹簧座441上，另一端抵触在断路器的基座上或与基座固定连接的其他部件上，锁扣弹簧3使推动脚44向断路器的脱扣器推杆10侧转动。通过采用上述方案，我们很好的实现漏电断路器的动触头操作机构的小型化，具体表现在，动触头6的转动是通过动锁扣4、跳扣1、触头支架2与拉簧5的配合实现，这样简单的几个部件就实现动触头摆动，非常方便。动触头6具体运动的过程是，在静触头合闸时，锁扣4的抵触脚42与跳扣1抵触配合限制跳扣转动，当漏电断路器发生情况动作时，断路器的脱扣器推杆10推动推动脚43转动从而实现锁扣4转动，锁扣4转动使跳扣1与抵触脚42之间的抵触解锁，这时动触头支架2在拉簧5的作用下转动实现断路器分闸，同时手柄9也是转动到分闸状态；合闸动作，手柄9在外力作用下顺时针方向转动时，带动第一连杆8向右动作，第一连杆8推动跳扣1相对动触头支架2的长通孔21右侧边与销轴抵触配合，继续顺时针方向转动手柄9时，锁扣4继续绕销轴7顺时针方向转动，与此同时动触头支架2和动触头6在跳扣1推动下以及拉簧5的拉力作用下，绕动触点6与静触头接触点顺时针方向转动，此时动触头支架2上的长通孔21右侧边与销轴脱离，产生超行程，当手柄9不能继续推动时，漏电断路器产品闭合。这样使动触头6和静触头的接触更加紧密，并保证动触头6与静触头的良好接触。
在本发明实施例中，所述动触头支架2下方且位于基座一侧上设置容腔22，所述动触头6上端卡入容腔22实现与动触头支架2的固定连接，这样动触头6和动触头支架2之间的连接方便，所述动触头支架2的长通孔21位于容腔22部，所述动触头6上端设置有与动触头支架2的长通孔21对应的动触头长通孔61，所述销轴7穿过长通孔21和动触头长通孔61设置，这样使动触头支架2与动触头6均受到销轴7的力，运动比较稳固。所述锁扣4的复位脚44的顶端部还设置有连接孔442，该连接孔442上连接有第二连杆4421，第二连杆4421的另一端上抵触设置有双金属片4422，这样双金属片4422可以控制锁扣4移动从而实现过载保护。
在本发明实施例中，所述跳扣1上设置有卡台11，所述锁扣4的抵触脚42上设置有与跳扣卡台11抵触配合的抵触肩阶421，这里的卡台11或抵触肩阶421配合我们也可以采用其他的方式实现，如斜面抵触配合等，其目的是方便两者之间的抵触配合，实现在需要的时候固定动触头支架上端部，所述跳扣1上设置有供第一连杆8连接的连接通孔12，所述动触头支架2上方且与跳扣1的连接通孔12对应的位置处设置有弧形槽23，所述第一连杆8连接在跳扣1上后其穿出端置于弧形槽23内，并可在弧形槽23内滑移，这样对跳扣1与动触头支架2的转动进行了限定，使两者之间的配合更加合理，当然我们也可以不设置弧形槽23以及第一连杆8也不穿出设置，两者之间仅仅通过第一连杆8的长度进行限定配合。
在本发明实施例中，所述动触头支架2上且位于长通孔21上方设置有供拉簧挂设的长孔24，这样方便拉簧5连接，所述锁扣4的推动脚43上且靠近动触头6一侧设置有弧形凸起的凸筋431，锁扣4被断路器的脱扣器推杆10推动转动时，推动脚43的凸筋431顶部与动触头6抵触，此时动触头温度较高，因此凸筋431顶部与动触头6是线接触，接触面积小，锁扣4损伤小。
本发明所揭示，乃较佳实施例的一种，凡局部变更或是修饰而源于本发明的技术思想而为熟悉该技术的人员所易于推知者，皆不脱本发明的专利范畴。
