具体的，如图1所示方向，所述第一方向为顺时针方向，第二方向为逆时针方向。
优选的，如图9所示，按钮机构2只包括一个按钮的实施例。所述按钮机构2包括滑动设置在断路器外壳1内的第一按钮20，连杆结构33包括第一连杆30，第一按钮20通过第一连杆30与传动件4驱动相连；向所述断路器外壳1内部方向按压第一按钮20使断路器合闸时，第一按钮20驱动传动件4向第一方向转动，向断路器外壳1外部方向拉拔第一按钮20使断路器分闸时，第一按钮20驱动传动件4向第二方向转动。进一步的，如图9所示，所述第一按钮20一端突出在断路器外壳1外部，另一端通过第一连杆30与传动件4驱动相连，向下按压第一按钮20使断路器合闸时，第一按钮20通过第一连杆30驱动传动件4顺时针转动，向上拉拔第一按钮20使断路器分闸时，第一按钮20通过第一连杆30驱动传动件4逆时针转动。
优选的，如图1、7A-8B、10A-13A、15A-15C所示，按钮机构2包括两个按钮的实施例，这是本发明的优选方案。所述按钮机构2包括滑动设置在断路器外壳1内的第一按钮20和第二按钮21，第一按钮20和第二按钮21平行设置且同步反向移动；所述连杆结构33包括第一连杆30和第二连杆31，第一按钮20通过第一连杆30与传动件4驱动相连，第二按钮21通过第二连杆31与传动件4驱动相连；向所述断路器外壳1内部方向按压 第一按钮20使断路器合闸时，第一按钮20驱动传动件4向第一方向转动，同时第二按钮21向断路器外部方向移动，向所述断路器外壳1内部方向按压第二按钮21使断路器分闸时，第二按钮21通过第二连杆31驱动传动件4向第二方向转动，同时第一按钮20向断路器外部方向移动。
以下为本发明断路器的正常合闸操作、正常分闸操作和故障分闸的基本过程：
如图10A所示，所述断路器处于分闸状态，进行合闸操作时，向下按压第一按钮20，第一按钮20通过第一连杆30驱动传动件4顺时针转动，传动件4通过传动连杆32驱动杠杆机构整体顺时针转动，杠杆机构则带动动触头60顺时针摆动，使动触头60和静触头61闭合，断路器合闸完成(如图10B所示)，同时第二按钮21向断路器外部方向移动；如图10B所示，所述断路器处于合闸状态，进行分闸操作时，向下按钮第二按钮21，第二按钮21通过第二连杆31驱动传动件4逆时针转动，传动件4通过传动连杆32驱动跳扣50和锁扣51解除锁扣配合，转动板52带动动触头60逆时针摆动，使动触头60与静触头61分断，断路器分闸完成(如图10A所示)，同时第一按钮20向断路器外部方向移动。
所述断路器出现短路或过载故障时，短路保护机构7或过载保护机构9驱动锁扣51逆时针转动，使锁扣51与跳扣50解除锁扣配合，转动板52带动动触头60逆时针摆动，使动触头60与静触头61分断，断路器分闸(如图10A所示)。
优选的，如图6所示，为所述传动件4的一种实施方式。
如图6所示，所述传动件4包括设置在其中部的传动件轴孔400以及设置在传动件轴孔400周遭的第一连接孔40、第二连接孔41、第三连接孔42；所述第一连接孔40、第二连接孔41和第三连接孔42分别位于一个三角形的三个顶点处，第二连接孔41设置在传动件4一端，第一连接孔40和第三连接孔42设置在传动件4的另一端。具体的，如图6所示方向，所述传动件轴孔400设置在传动件4中部，第二连接孔41设置在传动件4的左端且位于传动件轴孔400左侧，第一连接孔40和第三连接孔42设置在传动件4的右端且二者位于传动件轴孔400右侧。
优选的，如图13A-13B所示，本发明的断路器还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，第一复位弹簧5a驱动第一锁定件1a一端通过锁定件开孔伸出到断路器外壳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，且第一锁定件1a缩回后可与第一按钮20和/或第二按钮21限位配合并使断路器无法进行合闸操作，所述断路器处于合闸状态时，第一锁定件1a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。例如所述断路器在分闸状态下被安装至断路器装配位的过程中，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与第一按钮20和/或第二按钮21限位配合，锁定第一按钮20和/或第二按钮21，断路器装配到位后，锁定件开孔与装配位壳体的装配限位孔对应，第一锁定件1a重新突出在断路器外壳1外部并解除与第一按钮20和/或第二按钮21的限位配合，解锁第一按钮20和/或第二按钮21且第一锁定件1a与装配位壳体限位配合，使断路器能够通过第一按钮20和/或第二按钮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13A-13B所示，所述断路器还包括解锁机构，解锁机构包括设置在断路器外壳1内且与第一锁定件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，向断路器外壳1外部方向拉拔拉拔件2a，拉拔件2a驱动第一锁定件1a克服第一复位弹簧5a的弹力向断路器外壳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第一按钮20和/或第二按钮21限位配合，此时进一步拉拔拉拔件2a能够将断路器从断路器装配位拔出；所述断路器处于合闸状态时，第一按钮20和/或第二按钮21阻止第一锁定件1a向断路器外壳1内部方向移动，此时通过解锁机构也无法使解锁机构缩回断路器外壳1内部。进一步的，如图13A-13B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；向所述断路器外壳1外部方向拉拔拉拔件2a，拉拔件2a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。进一步的，如图13A所示，所述拉拔件2a在断路器外壳1厚度方向上叠置在按钮机构2一侧，有利于提高断路器结构的紧凑性。进一步的，如图13A和13B所示，所述拉拔件2的移动方向，与第一按钮20和第二按钮21的移动方向彼此平行，与第一锁定件1a的移动方向互相垂直。
优选的，所述第一按钮20和/或第二按钮21上设有锁定件限位槽，第一锁定件1a上设有锁定件限位凸台，断路器合闸时，第一按钮20和第二按钮21的移动使锁定件限位槽与锁定件限位凸台错位设置，锁定件限位凸台无法滑入锁定件限位槽，断路器分闸时，第一按钮20和第二按钮21的移动使锁定件限位槽和锁定件限位凸台相对设置，拉拔拉拔件2可驱动第一锁定件1a向断路器外壳1内部方向移动，使锁定件限位凸台滑入锁定件限位槽中，第一锁定件1a锁定第一按钮20和/或第二按钮21，断路器无法合闸。
如图1-8B所示，为本发明断路器的第一实施例。
如图1、7A-8B所示，本实施例的断路器，其按钮机构2包括第一按钮20和第二按钮21；所述电动机构2c包括驱动电机20c、传动齿轮组和传动齿条26c，驱动电机20c通过传动齿轮组与传动齿条26c驱动配合，传动齿条26c与第一按钮20驱动配合。进一步的，如图4所示，所述第一按钮20包括设置在其一侧的齿条限位槽2030，传动齿条26c设置在齿条限位槽2030内，齿条限位槽2030包括分别设置在其两端的合闸侧面2032和分闸侧面2031；驱动电机20c驱动传动齿条26c在齿条限位槽2030内滑动，通过合闸侧面2032和分闸侧面2031驱动第一按钮20使断路器合闸/分闸。所述断路器合闸时，传动齿条26c从第一初始位置向合闸侧面2032移动至与其接触，传动齿条26c继续移动并通过合闸侧面2032驱动第一按钮20向断路器外壳1内部方向移动，断路器合闸后，传动齿条26c返回第一初始位置；所述断路器分闸时，传动齿条26c向分闸侧面2031移动至与其接触，传动齿条26c继续移动并通过分闸侧面2031驱动第一按钮20向断路器外壳1外部方向移动，断路器分闸后，传动齿条26c返回第一初始位置。本发明的断路器，电动机构2c通过传动齿条26c与按钮机构的配合实现合闸/分闸操作，且电动机构2c完成合闸/分闸操作后，继续驱动传动齿条26c 返回至第一初始位置，从而不会与第一按钮20产生干涉，一则用户依然可以通过手动操作的方式对断路器进行分闸/合闸操作，二来当断路器出现短路或过载故障导致断路器跳闸时，传动齿条26c也不会影响操作机构的动作，保证了断路器的保护性能。需要指出的，所述传动齿条26c并不仅限于与第一按钮20配合，传动齿条26c也可以与第二按钮21配合，则齿条限位槽2030设置在第二按钮21一侧，断路器合闸/分闸时，传动齿条26c的移动方向与第一实施例的传动齿条26c相反。

具体的，如图11A所示，所述断路器处于分闸状态，第一扇形齿轮251c与传动件齿轮27c脱离啮合，断路器合闸时，驱动电机20c驱动第一扇形齿轮251c逆时针转动至与传动件齿轮27c啮合，第一扇形齿轮251c被驱动继续转动并驱动传动件齿轮27c顺时针转动，传动件齿轮27c带动传动件4顺时针转动，如图11B所示，断路器完成合闸，第一扇形齿轮251c被驱动继续转动至与传动件齿轮27c脱离啮合；如图11B所示，所述断路器处于合闸状态，第一扇形齿轮251c与传动件齿轮27c脱离啮合，断路器分闸时，驱动电机20c驱动第一扇形齿轮251c顺时针转动至与传动件齿轮27c啮合，第一扇形齿轮251c被驱动继续转动并驱动传动件齿轮27c逆时针转动，传动件齿轮27c带动传动件4逆时针转动，如图11A所示，断路器完成分闸，第一扇形齿轮251被驱动继续转动至与传动件齿轮27c脱离啮合。
优选的，本实施例的传动齿轮组与第三实施例相同，区别在于各齿轮的位置关系、尺寸有所不同，也可以调整齿轮的数量。
如图15A-15C所示，为本发明断路器的第五实施例。
本实施例与第四实施例的不同点在于：所述传动件齿轮27c和传动件4同轴设置，二者之间设有空行程。
所述断路器合闸时，分合闸驱动齿轮向第二方向转动并驱动传动件齿轮27c从第二初始位置向第一方向转动至与传动件4限位配合，传动件齿轮27c带动传动件4向第一方向转动，断路器合闸且分合闸驱动齿轮向第一方向转动驱动传动件齿轮27c回转至第二初始位置；所述断路器分闸时，分合闸驱动齿轮向第一方向转动并驱动传动件齿轮27c从第二初始位置向第二方向转动至与传动件4限位配合，传动件齿轮27c带动传动件4向第二方向转动，断路器分闸且分合闸驱动齿轮向第二方向转动驱动传动件齿轮27c回转至第二初始位置。进一步的，所述分合闸驱动齿轮为第一扇形齿轮251c或者全齿轮。
具体的，所述如图15A所示，所述断路器处于分闸状态，断路器合闸时，驱动电机20c驱动分合闸驱动齿轮逆时针转动，分合闸驱动齿轮驱动传动件齿轮27c从第二初始位置顺时针转动至与传动件4限位配合，传动件齿轮27c继续转动并带动传动件4顺时针转动，如图15B所示，断路器完成合闸，如图15C所示，分合闸驱动齿轮被驱动顺时针转动并驱动传动件齿轮27c逆时针转动回转至第二初始位置。如图15C所示，所述断路器处于合闸状态，断路器分闸时，驱动电机20c驱动分合闸驱动齿轮顺时针转动，分合闸驱动齿轮驱动传动件齿轮27c逆时针转动至与传动件4限位配合，传动件齿轮27c继续转动并带动传动件4逆时针转动，断路器完成分闸，如图15A所示，分合闸驱动齿轮被驱动逆时针转动并驱动传动件齿轮27c回转至第二初始位置。
本发明的断路器，其传动件齿轮27c与传动件4之间设有空行程(即传动件齿轮27c转动一定角度后才能限位带动传动件4同步转动，则传动件4开始转动之前，传动件齿轮27c转过的角度即为其空行程)，从而在电动机构2c通过操作机构驱动断路器完成分闸/合闸操作后，传动件齿轮27c回转至第二初始位置，不会对传动件4形成干涉，一则用户可以通过手动方式完成断路器分闸/合闸操作，二者断路器因短路或过载故障时，可以顺利跳闸，保证了断路器的保护性能。
如图12A和12B所示，为本发明断路器的第六实施例。

优选的，如图12B所示，为所述脱扣杠杆3c配合的一种实施例。
如图12B所示，所述脱扣杠杆3c枢转安装在断路器外壳1内，两端分别与第四传动齿轮250c、锁扣51配合；所述锁扣51背面设有与脱扣杠杆3c一端对应配合的锁扣驱动凸台511，第四驱动齿轮250c背面设有与脱扣杠杆3c另一端对应配合的第四驱动齿轮驱动凸起2500c；如图12A所示，断路器分闸时，驱动电机20c驱动第一扇形齿轮251C及第四传动齿轮250c逆时针转动(图12B中为顺时针)，第四传动齿轮驱动凸起2500c驱动脱扣杠杆3c顺时针转动(图12B中为逆时针)，脱扣杠杆3c转动驱动锁扣51逆时针转动(图12B中为顺时针)触发脱扣分闸。进一步的，如图12B所示，所述脱扣杠杆3c为V字形结构，其中部设有脱扣杠杆轴孔。当然，脱扣杠杆3c还可以采用其它的类似结构。
优选的，本实施例的传动齿轮组与第四实施例的结构相同。
如图1、9-13A所示，为本发明断路器的第七实施例。
本发明的断路器还包括设置在断路器外壳1内的灭弧系统8、分别与操作机构驱动配合的短路保护机构7、过载保护机构9、进线端子1i和出线 端子1o；所述出线端子1o和按钮机构2设置在断路器外壳1一端，进线端子1i设置在断路器外壳1另一端，灭弧系统8和短路保护机构7并排设置在操作机构和进线端子1i之间，电动机构2和过载保护机构9位于操作机构同一侧且位于灭弧系统8和出线端子1o之间。进一步的，如图1所示，所述按钮机构2与短路保护机构7相对设置，位于断路器外壳1一侧；所述出线端子1o和灭弧系统8相对设置，位于断路器外壳1另一侧。具体的，如图1所示方向，如图1所示方向，以图1的上、下、左、右侧为断路器的上、下、左、右侧，以图1面向读者的一侧为断路器的前侧；所述出线端子1o和按钮机构2左右并排设置在断路器外壳1上端，出线端子1i设置在断路器外壳1的下端，灭弧系统8和短路保护机构7左右并排设置在操作机构和进线端子1i之间，电动机构2和过载保护机构9均位于操作机构的左侧且位于灭弧系统8和出线端子1o之间。
优选的，如图1和14所示，所述断路器还包括与电动机构2c相连的控制线路板1c。
优选的，如图1所示，所述控制线路板1c设置在断路器外壳1的底板和电动机构2c之间，控制线路板1c和电动机构2c位于操作机构的同一侧且控制线路板1c位于出线端子1o和灭弧系统8之间。具体的，如图1所示方向，以图1的上、下、左、右侧为断路器的上、下、左、右侧，以图1面向读者的一侧为断路器的前侧；所述控制线路板1c和电动机构2c位于操作机构的按钮机构2的左侧，控制线路板1c位于断路器外壳1的底板的前侧，电动机构2c位于控制线路板1c的前侧，控制线路板1c的位置基本与电动机构2c的位置重合，电路板的空间较小。
优选的，如图1所示，所述断路器还包括与控制线路板1c相连的信号端子，信号端子和进线端子1i设置在断路器外壳1的同一端且信号端子位于两个进线端子1i之间。
优选的，如图13A所示，所述短路保护机构7为电磁脱扣器。
优选的，如图13A所示，所述过载保护机构9是串接在断路器的L极电路中的锰铜电阻，锰铜电阻与控制线路板1c相连，锰铜电阻向控制线路板1c传输信号，若出现过载故障，则电动机构2c驱动断路器分闸。
优选的，所述过载保护机构9是耦合在断路器的L极电路上且与控制线路板1c相连的电流互感器，电流互感器采集L极电路的电流信号并传输给控制线路板1c，出现过载故障时，电动机构2c驱动断路器分闸。
优选的，所述过载保护机构9是与跳扣51驱动配合的双金属片，出现过载故障时，双金属片弯曲并驱动跳扣51转动，使锁扣50和跳扣51解除锁扣配合，断路器分闸。
优选的，如图1所示，所述断路器外壳1包括设置在其一端的进线端子孔14和信号端子孔15，以及设置在断路器外壳1另一端的出线端子孔、第一按钮孔和第二按钮孔；所述进线端子、信号端子、出线端子分别设置与对应的开孔中，第一按钮20一端滑动设置在第一按钮孔中，另一端与第一连杆30相连，第二按钮21一端滑动设置在第二按钮孔中，另一端与第二连杆31相连。
由于控制线路板1c不仅需与电动机构2c连接，过载保护机构9连接(如锰铜电阻或电流互感器时)，而且还需与进线端子1i连接取电，与信号端子连接传送信号，控制线路板1c如采用图1所示的实施例，则控制线路板1c与进线端子1i和信号端子连接时，走线较远且通过软导线连接， 则会给装配时走线焊接带来较大难度，无论是人工装配还是自动化装配，都很难控制导线的位置。
优选的，如图14所示的控制线路板1c的优选实施例，所述断路器外壳1的底板位于控制线路板1c的一侧，电动机构2c、操作机构、灭弧系统8位于控制线路板的另一侧，控制线路板1c至少延伸超过短路保护机构7和灭弧系统8且与进线端子1i和信号端子邻近，在控制线路板1c上布设有延伸超过灭弧系统8的用于与进线端子1i和信号端子连接的印制导线。具体的，如图1所示方向，以图1的上、下、左、右侧为断路器的上、下、左、右侧；所述断路器外壳1的底板位于控制线路板1c左侧，电动机构2c、操作机构和灭弧系统8位于控制线路板的右侧。进一步的，所述按钮机构2和短路保护机构7均直接设置在断路器外壳1的底板上。需要指出的是，根据实际需要，所述按钮机构2和短路保护机构7也可以与电动机构2c、操作机构、灭弧系统8一样，设置在控制线路板1c的另一侧，以进一步扩大控制线路板1c的安装空间。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
