Description

断路器 技术领域
本发明涉及低压电器领域，具体涉及一种断路器。
背景技术
断路器的广泛使用有效提高了电器使用的安全性，为了满足电器设备的小型化发展趋势，与之适配的断路器的整体结构和操作方式也需要不断升级和改进；在充分调查和研究现有技术后，发现现有断路器多存在以下不足：
一、现有的插入式断路器，多通过设置单独的分合闸指示结构，以指示断路器的分合闸转状态，从而造成断路器内部结构复杂和整体体积变大的问题；而且，操作机构的按钮多突出在断路器外壳的外部，容易因误触发生断路器的误操作，影响用电的稳定性和安全性。
二、现有的插入式断路器一般具有两种锁定机构，一种是防止断路器未安装到位进行合闸的，另一种是防止断路器在合闸状态下被插入或拔出机柜的，二者的结构复杂，占用了很多断路器内部空间。
三、现有插入式断路器一般通过拉拔按钮，将断路器从断路器装配位拉出；而用户在拉拔按压进行分闸操作时，往往会因为操作力度把握不准直接将断路器从断路器装配位拔出，影响用户的用电稳定性和安全性。
四、现有插入式断路器的断路器外壳设计不合理，外壳上设置的开孔分散，不便于断路器的安装。

本发明的断路器，其按钮机构包括合闸按钮和分闸按钮，用户可分别按压合闸按钮/分闸按钮驱动断路器合闸/分闸，而且合闸按钮和分闸按钮的移动方向相反，即向断路器外壳内部方向按压合闸按钮/分闸按钮使断路器合闸/分闸时，分闸按钮/合闸按钮向断路器外壳外部方向移动，也就是说用户可以通过观察合闸按钮和分闸按钮的状态以区分断路器所处状态(合闸或分闸状态)；一则与现有采用按压/拉拔按钮机构实现断路器合闸/分闸的断路器相比，本发明的断路器均通过按压按钮实现断路器的合闸/分闸，因此避免了断路器被误拔出的情况发生，第二通过观察合闸按钮和分闸按钮的状态，既可以判断断路器的状态，因此无需单独设置分合闸指示装置，简化了断路器的结构并节省了断路器的内部空间，还有利于断路器的小型化发展趋势，第三合闸按钮操作端和分闸按钮操作端分别设置在合闸按钮孔和分闸按钮孔内，能够不突出断路器外壳，避免因误触对断路器误操作。
此外，所述第一锁定件受到缩进外力时能缩进断路器外壳内部并锁定合闸按钮和/或分闸按钮，使断路器无法合闸，因此本发明插入式断路器未装配至断路器指定装配位时，断路器装配壳体挤压第一锁定件使其向断路器外壳内部方向移动并锁定合闸按钮和/或分闸按钮，避免插入式断路器在安装过程中，因未安装到位仍能合闸，保证了用户的人身安全；而且，所述断路器处于合闸状态时，合闸按钮和/或分闸按钮阻止第一锁定件向断路器外壳内部方向移动，因此本发明的插入式断路器一旦断路器被合闸，则无法安装至断路器装配位，从而保证了断路器是在分闸状态下被安装至断路器装配位，还保证了断路器在合闸状态下不能从断路器装配位拔出，从而保证了用户的人身安全。
此外，所述第二锁定件的第二锁定端在断路器合闸/分闸状态下，突出/缩入断路器外壳外部/内部，从而避免了断路器在合闸状态下被装入断路器装配位或者在合闸状态下被拉出断路器装配位的情况发生，保证了用户的用电安全性 和人身安全；进一步的，本发明的插入式断路器，其按钮机构包括合闸按钮和分闸按钮，用户可分别按压合闸按钮/分闸按钮驱动断路器合闸/分闸，而且合闸按钮和分闸按钮的移动方向相反，即向断路器外壳内部方向按压合闸按钮/分闸按钮使断路器合闸/分闸时，分闸按钮/合闸按钮向断路器外壳外部方向移动，也就是说用户可以通过观察合闸按钮和分闸按钮的状态以区分断路器所处状态(合闸或分闸状态)。

具体实施方式
以下结合附图1-25给出的实施例，进一步说明本发明的断路器的具体实施方式。本发明的断路器不限于以下实施例的描述。
如图1所示，本发明的断路器，尤其是一种插入式断路器，其包括断路器外壳1以及设置在断路器外壳1内部的按钮机构2、与按钮机构2连接的操作机构、与操作机构相连的动触头60和与动触头60配合使用的静触头61；操作所述按钮机构2能通过操作机构驱动断路器分闸/合闸，使动触头60静触头61闭合/断开。
当然根据需要，如图1所示，本发明的断路器还可以包括设置在断路器外壳1内部的短路保护机构7、过载保护机构和灭弧系统8；所述短路保护机构7和过载保护机构分别在断路器出现短路和过载故障时，驱动操作机构动作使断路器跳闸，以实现基本的电路保护功能；所述灭弧系统8则用于熄灭动触头60和静触头61分断时产生的电弧，有利于提高断路器的分断性能，提高用电安全性。
如图1-3所示，所述断路器外壳1包括设置在其上的合闸按钮孔110和分闸按钮孔111；所述按钮机构2包括分别滑动设置在断路器外壳1内部的合闸按钮20和分闸按钮21，合闸按钮20包括设置在其一端且滑动设置在合闸按钮孔110内的合闸按钮操作端，分闸按钮21包括设置在其一端且滑动设置在分闸按钮孔111内的分闸按钮操作端；向所述断路器外壳1内部方向按压合闸按钮操作端/分闸按钮操作端驱动操作机构使断路器合闸/分闸时，同时对应的分闸按钮操作端/合闸按钮操作端向断路器外壳1外部方向移动。
进一步的，如图1和2所示，所述操作机构包括连杆机构、枢转设置在断路器外壳1内的传动件4和杠杆机构，连杆机构包括合闸连杆30、分闸连杆31和传动连杆32；所述合闸按钮20另一端通过合闸连杆30与传动件4驱动相连，分闸按钮21另一端通过分闸连杆31与传动件4驱动相连，传动件4通过传动连杆32与杠杆机构驱动相连，杠杆机构与断路器的动触头60相连；按压所述合闸按钮20使断路器合闸时，合闸按钮20通过合闸连杆30驱动传动件4向第一方向转动，同时传动件4的转动通过分闸连杆31驱动分闸按钮21向断路器外壳1外部方向移动；按压所述分闸按钮21使断路器分闸时，分闸按钮21通过分闸连杆31驱动传动件4向第二方向转动，同时传动件4的转动通过合闸连杆30驱动合闸按钮20向断路器外壳1外部方向移动，第一方向和第二方向互为反方向。其中，所述传动件4功能近似于传统小型断路器的手柄，合闸按钮20和分闸按钮21通过连杆与传动件4联动，所述的连杆机构可以采用现有的四连杆或多连杆等现有方案。
本发明的断路器，一个改进点在于按钮机构2包括合闸按钮20和分闸按钮21，用户可分别按压合闸按钮20/分闸按钮21驱动断路器合闸/分闸，而且合闸按钮20和分闸按钮21的移动方向相反，即向断路器外壳1内部方向按压合闸按钮20/分闸按钮21使断路器合闸/分闸时，同时对应的分闸按钮21/合闸按钮20向断路器外壳1外部方向移动，也就是说用户可以通过观察合闸按钮20和分闸按钮21的状态以区分断路器所处状态(合闸或分闸状态)；一则与现有采用 按压/拉拔按钮机构实现断路器合闸/分闸的断路器相比，本发明的断路器均通过按压按钮实现断路器的合闸/分闸，因此避免了断路器被误拔出的情况发生，第二通过观察合闸按钮20和分闸按钮21的状态，既可以判断断路器的状态，因此无需单独设置分合闸指示装置，简化了断路器的结构并节省了断路器的内部空间，还有利于断路器的小型化发展趋势。
优选的，如图10-24所示，本发明的断路器还包括设置在断路器外壳1内部的锁定机构和解锁机构。如图10-18所示，所述锁定机构包括一端突出在断路器外壳1外部的第一锁定件1a，同时在断路器外壳1上设有与锁定机构配合的锁定件开孔17，在断路器装配位的的装配位壳体上设有装配限位孔，当断路器装配到位后，插入式断路器的锁定件开孔17与装配限位孔对应，当插入式断路器未安装到位时，插入式断路器的锁定件开孔17与装配限位孔错位，装配位壳体会遮挡锁定件开孔17，这为本领域的现有技术，在此不再赘述。
本发明的另一个改进点在于锁定配合的结构，所述断路器处于分闸状态时，第一锁定件1a一端从锁定件开孔17伸出，突出在断路器外壳1外部，第一锁定件1a受到缩进外力能够缩回断路器外壳1内部，且第一锁定件1a与合闸按钮20和/或分闸按钮21限位配合，锁定合闸按钮20和/或分闸按钮21使断路器无法合闸；所述断路器处于合闸状态时，第一锁定件1a一端突出在断路器外壳1外部，且被合闸按钮20和/或分闸按钮21限位无法缩回断路器外壳1内部。当第一锁定件1a突出在断路器外壳1外部时，第一锁定件1a没有锁定合闸按钮20和/或分闸按钮21，此时合闸按钮20和/或分闸按钮21能够进行正常的分合闸操作。
优选的，如图10-17所示，所述断路器安装至断路器装配前，如果断路器处于合闸状态，第一锁定件1a一端突出在断路器外壳1外部，且被合闸按钮20和/或分闸按钮21限位无法缩回断路器外壳1内部，使得断路器在合闸状态无法插入安装到断路器装配位内；
所述断路器安装至断路器装配位时，在装配过程中断路器装配位的装配位壳体对第一锁定件1a施加缩进外力，挤压第一锁定件1a使其向断路器外壳1内部方向移动，缩回断路器外壳1内部，且使第一锁定件1a与合闸按钮20和/或分闸按钮21限位配合，锁定合闸按钮20和/或分闸按钮21使断路器无法合闸，使得在装配过程中断路器无法合闸提高安全性；
在断路器装配到位后，锁定件开孔17与装配限位孔对应，装配位壳体不对第一锁定件1a施加缩进外力，第一锁定件1a重新突出在断路器外壳1外部，解锁按钮机构2且第一锁定件1a与装配位壳体限位配合，使断路器能够通过合闸按钮20或分闸按钮21进行正常的合闸和分闸操作，且不允许随意从断路器装配位中拔出，确保运输过程中的振动不会使断路器从断路器装配位掉出；
在断路器装配到位后，所述断路器处于合闸状态时，合闸按钮20和/或分闸按钮21阻止第一锁定件1a向断路器外壳1内部方向移动，使得在合闸状态下断路器不能从断路器装配位中拔出。
进一步的，如图10-13和18所示，所述断路器处于分闸状态时，操作解锁机构能驱动第一锁定件1a向断路器外壳1内部方向移动，缩回断路器外壳1内部，解除第一锁定件1a与装配位壳体的限位配合并与按钮机构2限位配合。
本发明的断路器的锁定机构通过与合闸按钮20和/或分闸按钮21配合，在安装至断路器装配位时，其锁定机构的第一锁定件1a锁定合闸按钮20和/或分闸按钮21，避免断路器在安装过程中，因用户误操作/误触使断路器合闸的情况发生，保证了用户的人身安全；而且，所述断路器处于合闸状态时，合闸按钮 20和/或分闸按钮21阻止第一锁定件1a向断路器外壳1内部方向移动，也就是说，一旦断路器被合闸，则无法安装至断路器装配位，或者无法从断路器装配位被随意拔出，从而保证了断路器是在分闸状态下被安装至断路器装配位，或者能够被从断路器装配位拔出，从而保证了用户的人身安全。
需要指出的是，所述“锁定/解锁按钮机构2”指的是，通过第一锁定件1a与按钮机构2的进行限位配合/解除限位配合，阻止/允许合闸按钮20和/或分闸按钮21进行设计方向(即合闸方向或分闸方向)的移动。
所述断路器装配至断路器装配位且装配到位后，第一锁定件1a与断路器装配位的装配位壳体限位配合；所述解锁机构包括与第一锁定件1a驱动配合的独立的拉拔件2a，所述断路器处于分闸状态时，拉动拉拔件2a能驱动第一锁定件1a向断路器外壳1内部方向移动，缩回断路器外壳1内部，使第一锁定件1a解除与装配位壳体的限位配合，断路器能够从断路器装配位中拔出。进一步的，如图10-13所示，所述解锁机构还包括联动件3a，联动件3a一端与第一锁定件1a驱动配合，另一端与拉拔件2a驱动配合，拉动所述拉拔件2a能驱动联动件3a转动，驱动第一锁定件1a向断路器外壳1内部方向移动，缩回断路器外壳1内部并解除与装配位壳体的限位配合。与现有的采用拉拔按钮的方式解除与装配位壳体的限位配合的断路器相比，本发明的又一改进点在于断路器单独设置了解锁机构的拉拔件2a，不采用按钮机构去解锁第一锁定件，从而避免了因拉拔按钮将断路器误拔出的情况发生。而且，本发明的解锁机构，其拉拔件2a通过联动件3a与第一锁定件1a驱动配合，从而提高了解锁机构的容错能力，从而降低了对于拉拔件2a、联动件3a和第一锁定件1a的结构精准度要求，有利于降低生产难度，提高生产效率。
优选的，如图21-24所示，所述锁定机构包括枢转设置在断路器外壳1上的第二锁定件1b，第二锁定件1b包括第二锁定端13b；按压合闸按钮20驱动操作机构使断路器合闸，同时使分闸按钮21向断路器外壳1外部方向移动，合闸按钮20和/或分闸按钮21驱动第二锁定件1b转动，使第二锁定端13b突出在断路器外壳1外部，且第二锁定件1b被合闸按钮20和/或分闸按钮21限位无法缩回断路器外壳1内部，按压分闸按钮21驱动操作机构使断路器分闸，同时使合闸按钮20向断路器外壳1外部方向移动，分闸按钮21和/或合闸按钮20驱动第二锁定件1b反向转动，使第二锁定端13b缩入断路器外壳1内。
进一步的，如图22和24所示，所述断路器合闸时，分闸按钮21驱动第二锁定件1b转动，使第二锁定端13b突出在断路器外壳1外部，断路器分闸时，合闸按钮20驱动第二锁定件1b转动，使第二锁定端13b缩入断路器外壳1内部。当然，所述断路器合闸时，也可以由合闸按钮20驱动第二锁定端13b突出在断路器外壳1外部，分闸时由分闸按钮21驱动第二锁定端13b缩入断路器外壳1内部。本发明的断路器，其锁定机构还包括第二锁定件1b，第二锁定件1b的第二锁定端13b在断路器合闸下，突出断路器外壳1外部，从而避免了断路器在合闸状态下被装入断路器装配位或者在合闸状态下被拉出断路器装配位的情况发生，保证了用户的用电安全性和人身安全。
需要说明的是本发明锁定机构的第一锁定件1a和第二锁定件1b，两者的功能有一定的重合性，也有不同，可以同时存在以提高断路器的用电安全性，当然也可以仅设置第一锁定件1a或第二锁定件1b。当同时设置第一锁定件1a和第二锁定件1b时，断路器在断路器装配位外合闸，则第一锁定件1a和第二锁定件1b均突出断路器外壳，断路器无法安装到断路器装配位内；断路器安装到断路器装配位时，未安装到位，第一锁定件1a被装配位壳体压回断路器外壳 内，阻止合闸按钮合闸；断路器安装到断路器装配位后且安装到位后合闸，第一锁定件1a和第二锁定件1b均突出断路器外壳，且无法解锁，无法从断路器装配位拔出；断路器安装到断路器装配位后且分闸，第二锁定件1b退回断路器外壳内，第一锁定件1a仍然凸出断路器外壳，防止运输等情况晃动时断路器与断路器装配位脱离；断路器安装到断路器装配位后且分闸，向外拉动拉拔件2a，拉拔件2a将第一锁定件1a拉回至断路器外壳内解锁，继续拉动第一锁定件1a带动断路器拉出机柜。
优选的，如图19、20和25所示，为所述断路器外壳1的一种实施方式。
所述断路器外壳1整体成六面体机构，其包括相对设置的前侧壁1001和后侧壁1002，设置在前侧壁1001上的出线孔112、按钮孔110-111和拉拔件操作孔113，以及设置在后侧壁1002上的进线孔14。所述断路器外壳1的出线孔112、按钮孔110-111和拉拔件操作孔113集中设置于前侧壁1001，更加便于用户操作，进线孔14设置在与前侧壁1001相对的后侧壁1002上，有利于增大进线端和出线端的爬电距离，有利于提高断路器的绝缘性能。进一步的，如图25所示，所述按钮孔110-111包括并排设置的合闸按钮孔110和分闸按钮孔111。上述结构，便于断路器的合闸按钮和分闸按钮的分开设置，从而通过不同结构实现断路器合闸/分闸操作，与现有的通过按压/拉拔按钮实现断路器合闸/分闸的断路器相比，避免了因拉拔按钮使断路器分闸时，用力过猛将断路器拉出的情况发生。

优选的，如图10-17所示，所述锁定机构包括一端突出在断路器外壳1外 部的第一锁定件1a，所述断路器外壳1包括与第一锁定件1a配合的锁定件开孔17，第一锁定件1a一端通过锁定件开孔17伸出到断路器外壳1外部，所述断路器处于分闸状态时，第一锁定件1a受到缩进外力能够缩回断路器外壳1内部；例如所述断路器安装至断路器装配位时，在装配过程中，断路器装配位的装配位壳体挤压第一锁定件1a使其向断路器外壳1内部方向移动(装配位壳体向第一锁定件1a施加缩进外力)，使第一锁定件1a与合闸按钮20和/或分闸按钮21限位配合，锁定合闸按钮20和/或分闸按钮21使断路器无法合闸，断路器装配到位后，锁定件开孔17与装配位壳体的装配限位孔对应，第一锁定件1a重新从锁定件开孔17突出在断路器外壳1外部并解除与合闸按钮20和/或分闸按钮21的限位配合，解锁按钮机构且第一锁定件1a与装配位壳体的装配限位孔限位配合，使断路器能够通过合闸按钮20或分闸按钮21进行正常的合闸和分闸操作，且不允许随意从装配位中拔出。
进一步的，如图14-17所示，所述合闸按钮20和/或分闸按钮21包括用于与第一锁定件1a限位配合的按钮限位槽216，第一锁定件1a包括与按钮限位槽216匹配的第一锁定件限位台14a；所述断路器处于合闸状态时，按钮限位槽216与第一锁定件限位台14a错位设置，合闸按钮20和/或分闸按钮21阻止第一锁定件1a向断路器壳体1内部方向移动；所述断路器处于分闸状态时，按钮限位槽216与第一锁定件限位台14a相对设置，第一锁定件1a能向断路器外壳1内部方向移动，使第一锁定件限位台14a滑入按钮限位槽216内。
优选的，如图10-15所示，所述合闸按钮20与分闸按钮21平行设置且直线滑动安装在断路器外壳1内，所述第一锁定件1a直线移动的安装在壳体6内，所述合闸按钮20与分闸按钮21的移动方向与第一锁定件1a的移动方向相互垂直。进一步的，如图10-15所示，所述锁定机构还包括设置在第一锁定件1a断路器外壳1之间的第一复位弹簧5a，第一复位弹簧5a向第一锁定件1a施加作用力，使第一锁定件1a一端在无其他外力干涉的情况下保持突出在断路器外壳1外部，断路器处于分闸状态时，第一锁定件1a受到缩进外力能够缩回断路器外壳1内部。
具体的，如图14和15所示，所述合闸按钮20和分闸按钮21能左右移动，且二者同步向相反方向移动，第一锁定件1a能上下移移动；如图14所示，所述断路器处于合闸状态，分闸按钮21的按钮限位槽216与第一锁定件1a的第一锁定件限位台14a错位设置，第一锁定件1a无法向下侧移动；如图15所示，所述断路器处于分闸状态，分闸按钮21的按钮限位槽216与第一锁定件1a的第一锁定件限位台14a相对设置，第一锁定件1a可以向下移动，使第一锁定件限位台14a滑入按钮限位槽，从而限制分闸按钮21和合闸按钮20的左右移动。需要指出的是，所述按钮限位槽216也可以设置在合闸按钮20上，只需满足断路器合闸状态下，按钮限位槽216与第一锁定件限位台14a错位设置，断路器分闸状态下，按钮限位槽216与第一锁定件限位台14a相对设置即可。
进一步的，如图14和15所示，所述合闸按钮20与分闸按钮21平行设置，合闸按钮20和第一锁定件1a均位于分闸按钮21的上方，即合闸按钮20和第一锁定件1a均位于分闸按钮21和锁定件开孔17之间，第一锁定件1a位于合闸按钮20的一侧，所述分闸按钮21包括用于与第一锁定件1a限位配合的按钮限位槽216，第一锁定件1a包括与按钮限位槽216匹配的第一锁定件限位台14a，所述合闸按钮20上设有用于避让第一锁定件1a的第一锁定件限位台14a的合闸按钮避让槽206。所述第一锁定件1a一端伸出在断路器外壳1外部时，第一锁定件限位台14a位于合闸按钮避让槽206内，合闸按钮避让槽206的宽度在 合闸按钮20的移动方向上远大于第一锁定件限位台14a的宽度，合闸按钮20在分合闸移动时不会与第一锁定件限位台14a接触，使合闸按钮20和分闸按钮21能够移动进行驱动断路器合闸和分闸；所述断路器处于合闸状态时，按钮限位槽216与第一锁定件限位台14a错位设置，且第一锁定件限位台14a位于合闸按钮避让槽206内，分闸按钮21阻止第一锁定件1a向断路器壳体1内部方向移动，所述断路器处于分闸状态时，按钮限位槽216与第一锁定件限位台14a相对设置，第一锁定件1a受到缩进外力能够向断路器外壳1内部方向移动，使第一锁定件限位台14a滑入按钮限位槽216内。
本优选实施例，所述合闸按钮20和第一锁定件1a设置在同一平面，均位于分闸按钮21的上方，使得结构更加的紧凑，在合闸按钮20上设有合闸按钮避让槽206，避让第一锁定件1a的第一锁定件限位台14a，使得合闸按钮20在合闸或分闸时移动不受影响；而且第一锁定件1a也能与分闸按钮21紧靠，进行解锁和锁定配合使第一锁定件1a需移动的距离也短，在分闸时第一锁定件限位台14a与分闸按钮21的按钮限位槽216对应，第一锁定件1a能够被压缩到断路器外壳1内，在合闸时第一锁定件限位台14a与分闸按钮21的按钮限位槽216错位，第一锁定件限位台14a被分闸按钮21限位使第一锁定件1a无法被压缩到断路器外壳1内，不能再合闸状态被从断路器装配位拔出。
优选的，如图10-13、18所示，本发明的断路器还包括与第一锁定件1a驱动相连的解锁机构；所述断路器处于分闸状态时，操作解锁机构能驱动第一锁定件1a向断路器外壳1内部方向移动，缩回断路器外壳1内部，解除与装配位壳体的限位配合并与按钮机构2限位配合；所述断路器处于合闸状态时，合闸按钮20和/或分闸按钮21阻止第一锁定件1a向断路器外壳1内部方向移动，确保合闸状态下不能解锁，保证用电安全。
进一步的，如图10-13所示，所述解锁机构包括与第一锁定件1a驱动配合的独立的拉拔件2a，断路器处于分闸状态时，拉动拉拔件2a能驱动第一锁定件1a向断路器外壳1内部方向移动，使第一锁定件1a解除与装配位壳体的限位配合。进一步的，如图10-13所示，所述解锁机构还包括联动件3a和设置在断路器外壳1上的杠杆支撑4a，联动件3a一端与第一锁定件1a驱动相连，另一端与拉拔件2a驱动配合，中部与杠杆支撑4a接触配合；拉动所述拉拔件2a能驱动联动件3a以杠杆支撑4a为支点转动，联动件3a驱动第一锁定件1a向断路器外壳1内部方向移动并解除与装配位壳体的限位配合。作为另一种实施例，所述解锁机构也可以不设置杠杆支撑4a，而是联动件3a通过一设置在联动件3a上的腰形孔和固定在断路器外壳1上的联动件转轴的配合转动安装在断路器外壳1内，一端与拉拔件2a配合，另一端与第一锁定件1a配合，拉动所述拉拔件2a时驱动联动件3a转动，使联动件3a另一端作用在第一锁定件1a上，使第一锁定件1a缩回断路器外壳1内部。
与现有的采用拉拔按钮的方式解除与装配位壳体的限位配合的断路器相比，本发明的又一改进点在于断路器单独设置了解锁机构的拉拔件2a，不采用按钮机构去解锁第一锁定件，从而避免了因拉拔按钮将断路器误拔出的情况发生。需要指出的是，本发明的独立的拉拔件2a，不仅适用于本发明的合闸按钮20和分闸按钮21的方案，也可以用于一个按钮实现分合闸操作的情况。
需要指出的，作为一种变换的实施方式，所述第一锁定件1a可以不设置第一锁定件限位台14a，则无论断路器合闸还是分闸，拉拔拉拔件2a均能驱动第一锁定件1a向断路器外壳1内部移动。
优选的，如图17所示，为所述第一锁定件1a的第一实施例。
如图17所示，所述第一锁定件1a包括第一锁定件主体10a、第一锁定件挡台11a、第一锁定件限位台14a和锁定件弹簧限位结构15a；所述第一锁定件挡台11a和第一锁定件限位台14a分别设置在第一锁定件主体10a两侧，锁定件弹簧限位结构15a设置在第一锁定件主体10a远离锁定件开孔17的一侧；所述第一锁定件主体10a一端通过设置在断路器外壳1上的锁定件开孔17突出在断路器外壳1外部，另一端通过锁定件弹簧限位结构15a与第一复位弹簧5a相连，第一复位弹簧5a一端与锁定件限位结构15a限位配合，另一端与断路器外壳1限位配合，第一锁定件挡台11a与断路器外壳1限位配合，阻止第一锁定件1a通过锁定件开孔17脱出。进一步的，如图17所示，所述第一锁定件1a还包括与解锁机构的联动件3a相连的第一锁定件受动部130a，第一锁定件受动部130a中部设有第一锁定件连接孔13a，联动件3a一端插装在第一锁定件连接孔13a内；所述第一锁定件受动部130a设置在第一锁定件主体10a一侧且位于第一锁定件主体10a和杠杆支撑4a之间。进一步的，如图所示，所述锁定件弹簧限位结构15a为弹簧限位凹槽。
优选的，如图16所示，为所述第一锁定件1a的第二实施例。
如图16所示，本实施例的第一锁定件1a与第一实施例的区别在于：未设置突出的第一锁定件受动部130a，而是第一锁定件主体10a一端突出在断路器外壳1外部，另一端的一侧设有第一锁定件连接孔13a作为第一锁定件受动部130a。进一步的，如图17所示，所述锁定件弹簧限位结构15为弹簧限位凸台。显然，第一锁定件1a根据需要还能设置其它类似的结构。
优选的，如图10、11A、11B、和18所示，为所述拉拔件2a的多个实施例。
所述拉拔件2a包括拉拔件操作部20a、拉拔件第一过渡部21a和拉拔件驱动部24a，拉拔件操作部20a与拉拔件第一过渡部21a垂直连接，所述拉拔件驱动部24a倾斜连接于拉拔件第一过渡部21a设置；所述拉拔件操作部20a构成便于人手或工具拉拔的操作部，拉拔件第一过渡部21a平行于拉拔件2a的移动方向构成滑动支撑，所述的拉拔件驱动部24a倾斜设置用于驱动联动件3a带动第一锁定件1a缩回断路器外壳1内部。一种实施方式为拉拔件2a只包括拉拔件操作部20a、拉拔件第一过渡部21a和拉拔件驱动部24a，此时拉拔件2a构成一个近似Z字型结构或U字型结构，Z字型结构其占用空间相对较大，U字型结构与锁定机构的滑动配合稳定性较差些。
进一步优选的实施例如图11A所示，还包括连接在拉拔件第一过渡部21a和拉拔件驱动部24a之间的拉拔件第二过渡部22a，拉拔件第二过渡部22a与拉拔件操作部20a平行且与拉拔件第一过渡部21a垂直，拉拔件第二过渡部22a和拉拔件操作部20a均位于拉拔件第一过渡部21a的一侧形成U字型，通过弯折缩小拉拔件2a所占用的空间，且拉拔件第二过渡部22a能用于拉出断路器和用于限位拉拔件2a的位置，拉拔件驱动部24a向远离拉拔件操作部20a且靠近拉拔件第一过渡部21a的一侧倾斜弯折。
进一步优选的实施例如图11B所示，还包括设置在拉拔件第二过渡部22a和拉拔件驱动部24a之间的拉拔件第三过渡部23a，第三过渡部23a与拉拔件第一过渡部21a平行设置，用于平衡拉拔件2a的滑动和调节拉拔件驱动部24a的位置；和/或，与拉拔件驱动部24a连接的拉拔件保持部25a，拉拔件保持部25a与拉拔件第一过渡部21a平行，倾斜的拉拔件驱动部24a逐步驱动联动件3a带动第一锁定件1a缩回断路器外壳1内部后，拉拔件保持部25a通过使联动件3a第一锁定件1a保持在缩回位置。
如图18所示拉拔件2a的优选实施例，所述拉拔件2a包括依次相连的拉拔 件操作部20a、拉拔件第一过渡部21a、拉拔件第二过渡部22a、拉拔件第三过渡部23a、拉拔件驱动部24a和拉拔件保持部25a；所述拉拔件操作部20a和拉拔件第二过渡部22a平行设置，拉拔件第一过渡部21a、拉拔件第三过渡部23a和拉拔件保持部25a平行设置且垂直于拉拔件操作部20a，拉拔件驱动部24a倾斜设置，与拉拔件第三过渡部23a折弯相连的一端为驱动部第一端，与拉拔件保持部25a折弯相连的一端为驱动部第二端，驱动部第一端相对于驱动部第二端远离第一锁定件1a。进一步的，所述拉拔件2a一体成型，由金属材料冲压、折弯而成。
优选的，如图10-13所示，所述断路器外壳1还包括设置于拉拔件操作部20a和拉拔件第二过渡部22a之间的拉拔件限位筋6a；拉拔所述拉拔件2a驱动第一锁定件1a缩回断路器外壳1内部解除与装配位壳体的限位配合后，继续拉拔拉拔件2a使其与拉拔件限位筋6a限位配合，将断路器从断路器装配位处拔出。
具体的，如图10、11A和11B所示方向，所述第一锁定件1a右端突出在断路器外壳1外部，左端与联动件3a右端相连且通过第一复位弹簧5a与断路器外壳1相连，联动件3a中部与设置在第一锁定件1a上方的杠杆支撑4a接触配合，联动件3a左端与拉拔件驱动部24a驱动配合，拉拔件驱动部24a上端和下端分别为驱动部第一端和驱动部第二端；所述断路器处于分闸状态时，向上拉拔拉拔件2a直至拉拔件驱动部24a与联动件3a的左端接触(如图12所示)，如图13所示，继续拉拔拉拔件2a能驱动联动件3a以杠杆支撑4a为支点顺时针转动，则联动件3a右端驱动第一锁定件1a向左侧移动，并使第一锁定件1a右端全部缩入断路器外壳1内部并与按钮机构2限位配合，从而解除第一锁定件1a与装配位壳体的限位配合，且拉拔件保持部25a与联动件3a的左端限位配合，使第一锁定件1a保持在断路器外壳1内部。
优选的，如图11A所示，所述拉拔件2a由金属磁性材料制成，解锁机构还包括设置在断路器外壳1内与拉拔件操作部20a配合的拉拔件保持磁铁，保持磁铁安装在断路器外壳1上的凹槽105内，与拉拔件操作部20a磁吸配合。所述拉拔件保持磁铁能将拉拔件操作部20可靠的保持在断路器外壳内，在无需操作拉拔件2a时，即保证了断路器外观的整洁美观，而且避免拉拔件2a非预期的突出断路器外壳1，导致误操作或拉拔件2a损坏的情况发生。进一步，当操作拉拔件2a拔出到位时，拉拔件第二过渡部22a也能与拉拔件保持磁铁磁吸配合，使拉拔件保持在断路器外壳1外的拔出位置。
需要指出的，所述“磁吸配合”指的是，拉拔件操作部20a受拉拔件保持磁铁的吸引。所述拉拔件2a由金属磁性材料制成是指其能够被拉拔件保持磁铁磁吸，其不一定为磁铁。
优选的，如图1、19、20和25所示，所述断路器外壳1还包括出线孔112和拉拔件操作孔113，出线孔112、拉拔件操作孔113、合闸按钮孔110和分闸按钮孔111位于断路器外壳1的同一侧壁上，断路器外壳1还包括拉拔件抠槽16，拉拔件2a的拉拔件操作部20a设置在拉拔件操作孔113内，使拉拔件2a不外拉时不突出于断路器外壳1外，拉拔件抠槽16与拉拔件操作孔113连通，通过拉拔件抠槽16进行拉拔操作。
进一步，优选的方案所述拉拔件抠槽16设置在出线孔112和拉拔件操作孔113之间且被出线导线遮挡，拉拔件抠槽16两端分别与出线孔112和拉拔件操作孔113连通，仅当出线导线被拆除后，才能在拉拔件抠槽16处将拉拔件操作部20a从拉拔件操作孔113中抠出；或者，作为另一种优选方案，所述拉拔件 抠槽16设置在分闸按钮孔111和拉拔件操作孔113之间，断路器处于合闸状态时，分闸按钮21遮挡拉拔件抠槽16，断路器处于分闸状态时，分闸按钮21向断路器外壳1内部方向移动，让开拉拔件抠槽16，才能在拉拔件抠槽16处将拉拔件操作部20a从拉拔件操作孔113中抠出。当出线导线被拆除时，断路器处于分闸状态时才可将拉拔件拉出，上述结构的设置保证了仅在断路器处于分闸状态下，解锁机构才能解锁第一锁定件1a与装配位壳体的限位配合，避免断路器在合闸状态下，拉拔拉拔件2a，导致拉拔件2a被损坏或者断路器被带电拉出的情况发生，保证了用户的用电安全性。
优选的，如图11B所示的另一种拉拔件实施例，所述拉拔件2a还包括拉拔件弹簧限位部26a，拉拔件弹簧限位部26a与拉拔件操作部20a平行设置且分别位于拉拔件2a的两端；所述解锁机构还包括设置在拉拔件弹簧限位部26a和拉拔件限位筋6a之间的拉拔件复位弹簧7a。所述拉拔件复位弹簧7a能将拉拔件2a的拉拔件保持部20a可靠的保持在断路器外壳内。所述拉拔件弹簧限位部26a与拉拔件保持部25a折弯相连的，或者直接与拉拔件驱动部24a折弯相连。
