本发明的断路器，断路器极2的引出导电件45和漏电保护模块3的接线片配合形成接入主回路的插拔连接结构，断路器极2和漏电保护模块3分别为两个独立的模块，使模块化的断路器极2和漏电保护模块3在拼接过程中同时满足主回路穿过零序互感器34的要求，满足现有断路器模块化要求，且其接线更为简单方便。
如图1-13所示，断路器包括外壳，在外壳内设置有至少一个断路器极2，外壳包括至少一个用于装配断路器极2的安装腔，当外壳内设置有多个安装腔时，外壳可以包括多个固定设置在外壳内部的隔板，由相邻两个隔板之间的间隔形成安装腔，或者，外壳包括上盖、底座以及拼装在上盖与底座之间的隔板，其中由上盖与一个隔板盖合形成一个安装腔，底座与另一个隔板形成另一个安装腔，其余隔板分别两两相对形成多个独立的安装腔，这种独立的安装腔可以作为第一壳体11，相邻两个第一壳体11可以拼装在一起，如此，断路器的外壳包括多个拼装的第一壳体11。
在每个断路器极2内设有一相主线路，也就是在每个断路器极2内设置N相主线路或一相L相主线路，例如，断路器内设置有四个断路器极2，其中三个断路器极2均为L极并分别设置有一相L相主线路以及操作机构，一个断路器极2设有N相主线路和操作机构，或者，断路器内设置两个断路器极2，两个断路器极2都为L极，或者分别为L极和N极。当然，在同一断路器极2内同时设置两相主线路也可以，例如，在一个断路器极2中同时设置L相主线路和N相主线路，或者，在一个断路器极2内同时设置两相L相主线路也同样可以，在同一个断路器极中，优选仅设置一个操作机构。
本申请以两个断路器极2为例，每个断路器极2中仅设置一相主线路，也就是其中一个断路器极2作为L极设有L相主线路，另一个断路器极2作为N极设有N相主线路，由L相主线路和N相主线路共同形成断路器的主回路，L极和N极共同装配于同一个安装腔内，也就是L极、N极共同设置在同一个第一壳 体11内。
每个断路器极2包括连接于一相主线路的一对接线端子以及依次联动连接的手柄机构21、操作机构22以及触头机构，一对接线端子包括一个进线端子和一个出线端子，触头机构连接在一对接线端子之间用于控制一相主线路的通断，触头机构包括相互配合的动触头和静触头，动触头与操作机构22联动连接，静触头固定装配于与动触头相对的一侧，通过手动操作手柄机构21带动操作机构22，使动触头与静触头接触或分离以实现对断路器极2中主线路的通断控制。另外，每个断路器极2还可以设置有灭弧系统以及与操作机构22配合的短路保护机构和/或过载保护机构26，灭弧系统配合设置在触头机构的一侧用于熄灭动触头与静触头在分合闸过程中产生的电弧，短路保护机构或过载保护机构26在主回路发生短路或过载故障时触发操作机构22脱扣。
如图1-4所示，断路器极2的接线端子设置于外壳的至少一端，相邻两个断路器极2的进线端子(出线端子)位于外壳的同一端，手柄机构21转动装配与外壳(第一壳体11)的上部，操作机构22设置于手柄机构21的一侧，手柄机构21与操作机构22通过连杆联动连接，动触头连接于操作机构22的下部，相邻两个断路器极2的操作机构22、手柄机构21分别联动连接，灭弧系统的灭弧室24以及静触头固定于外壳(第一壳体11)的中部，其中静触头与动触头相对。

如图3、4所示，在L极中设置有短路保护机构和过载保护机构26，其中短路保护机构设置在手柄机构21与灭弧系统的灭弧室24之间，短路保护机构的一端与L极的操作机构22相对，过载保护机构26与短路保护机构分别设置在L极的操作机构22的两侧，过载保护机构26的一端与操作机构22配合，在N极中可以不设置短路保护机构、灭弧系统以及过载保护机构26。当然，N极中也可以设置短路保护机构、灭弧系统以及过载保护机构26，即采用类似L极的结构作为N极。另外，相邻的断路器极2的操作机构22可以共用部分零件，例如杠杆、触头支持、跳扣等，且手柄机构21和锁扣联动。
在其中一个断路器极2的一侧还设置有附件模块，也就是在第一外壳的一侧设置附件模块，本实施例的附件模块以漏电保护模块3为例，如图7-13所示，优选漏电保护模块3包括第二壳体12，第二壳体12与一个第一壳体11拼接，形成具有漏电保护功能的断路器，此时外壳包括一个第二壳体12以及至少一个第一壳体11，在第二壳体12内装配有漏电检测电路和漏电脱扣机构，其中漏电脱扣机构包括由漏电检测电路驱动的脱扣器37，漏电检测电路包括线路板35以及与线路板35连接的零序互感器34，在线路板35设置有用于驱动漏电脱扣机构的控制器，所述零序互感器34与L相主线路、N相主线路连接用于检测漏电信号，在漏电检测电路检测到漏电故障时可以驱动脱扣器37的顶杆动作，在顶杆完成动作后，在脱扣器37的顶杆一侧对应设置有推板39和指示件38，在与推板39对应的第二壳体12侧壁设有避让孔，相邻断路器极2的联动部穿过避让孔与推板39配合，在发生漏电故障时，脱扣器37触发推板39转动，使联动 部带动锁扣转动从而使操作机构脱扣，指示件38动作指示漏电，本实施例的漏电脱扣机构可以采用现有技术。
漏电保护模块3还设置有漏电测试机构，所述漏电测试机构包括从主回路取电的漏电测试回路，所述漏电测试回路包括试验按钮36、第一弹性件31和第二弹性件32，所述试验按钮36滑动装配于第二壳体12，第一弹性件31与第二弹性件32配合形成漏电试验回路的断点，按压试验按钮36使第一弹性件31发生弹性形变以接通漏电测试回路的断点，优选的，漏电测试回路中还串联有零序互感器34的漏电测试回路绕组，零序互感器34的漏电流检测绕组与线路板35连接。
本申请的一个改进点在于，所述附件模块与断路器极2分别为模块化结构，附件模块与断路器极2装配也采用两个模块结构拼装在一起，也就是本实施例的漏电保护模块3采用模块化结构，漏电保护模块3的第二壳体12与断路器极2的第一壳体11的拼装，由第一壳体11与第二壳体12拼装形成断路器的外壳，同时，漏电保护模块3拼装于断路器极2的一侧可以同时实现从断路器极2的主回路取电，优选漏电保护模块3采用插拔连接的方式接入断路器的主回路中，也就是，漏电保护模块3采用插拔连接的方式接入断路器极2的L相主线路、N相主线路中。需要说明的是，作为其它实施例，漏电保护模块3与断路器极2的L相主线路、N相主线路的取电也可以是接触取电，但接触取电的方式不如插拔连接稳定。
具体的，在第一壳体11与第二壳体12相邻的侧壁设有接线口，至少在断路器极的L相主线路或N相主线路上连接有一个引出导电件45，在漏电保护模块3的接线端子连接有接线片，引出导电件45和/或接线片通过接线口形成接入主回路的插拔连接结构，插拔连接结构的引出导电件45和/或接线片穿过零序互感器34的穿线孔。优选，至少一个引出导电件45设有接插部451，接插部451与第一壳体11侧壁的第一接线口111对应；接线片的一端形成接插片44，接插片44可以穿过零序互感器34的穿线孔，接插片44与第二壳体12侧壁的第二接线口121对应；优选的，接插片44成片状结构，接插部451为伸入第一接线口111的插槽，接插片44从第二壳体12伸出插入接插部451，与接插部451插接配合。当然，作为其它实施例，也可以接插部451从第一壳体11伸出且伸入第二壳体12内插接配合。作为其它实施例，也可以接线片上设有接插部451，引出导电件45一端形成接插片44，接插片44插入接插部451插接配合。由接线片与引出导电件45配合形成的插拔连接结构，在实现漏电保护模块3与断路器极2连接取电的同时使主回路穿过零序互感器34的穿线孔，省略了导线，利于缩小断路器的体积，使漏电保护模块3与断路器极2为两个独立模块，满足断路器的模块化发展。
优选的，在断路器的主回路连接有引出导电件45，也就是在断路器极2的N相主线路和其中一相L相主线路分别连接有引出导电件45，在第一壳体11、第二壳体12紧邻的一侧侧壁分别设置有引出导电件45相对应的接线口，即接线口设置在断路器极2厚度方向的外壳侧壁上，其中接线口与零序互感器34的接线口相对，具体的，接线口包括分别设置于第一壳体11侧壁中部的第一接线口111和设置于第二壳体12侧壁中部的第二接线口121，其中第一接线口111的数目可以与引出导电件45的数目相对应，第二接线口121的数目与接线片的数目一一对应，也可以在第一壳体11和第二壳体12的一侧仅设置一个第一接线口111和一个第二接线口121，使两个引出导电件45与同一个第一接线口111对应，两个接线片与第二壳体12的同一个第二接线口相对应，另外，两个引出导电件45可以延伸至第二壳体12内分别与两个接线片插接，或者，两个接线片延伸第二壳体12外分别与两个引出导电件45插接，或者，一个引出导电件 45延伸至第二壳体12内与一个接线片插接，另一个接线片延伸至第二壳体12外与另一引出导电件45插接，如此，使得漏电保护模块3与断路器极2插接时，使两个接线片可以分别与L相主线路、N相主线路插接取电。当然，断路器的其他附件模块也可以采用如此接线方式与断路器极2的主回路连接取电。
优选的，每个断路器极2包括分别设置于第一壳体11两端的进线端子和出线端子，在进线端子与出线端子之间连接有一相主线路，漏电保护模块3的两个接线端子分别为L极出线端子41-1b和N极出线端子41-2b，如此结构，既不影响漏电保护模块3从断路器极2的主回路取电，也可以保证在未拼接漏电保护模块3时不会影响断路器极2的正常接线使用；在拼接漏电保护模块3后可以不使用断路器极2的出线端子，可以通过遮挡板遮挡出线端子。
当然，断路器极2中也可以仅设置进线端子或出线端子，在本实施例中，将进线端子设置于断路器极2中，对应的将出线端子设置于漏电保护模块3内，也就是，L极进线端子41-1a和N极进线端子41-2a并列设置在第一壳体11的一端，漏电保护模块3包括设置于第二壳体12同一端的两个接线端子，两个接线端子分别为L极出线端子41-1b和N极出线端子41-2b，L极的L相主线路连接在L极进线端子41-1a和L极出线端子41-1b之间，N极的N相主线路连接在N极进线端子41-2a和N极出线端子41-2b之间，如此，在漏电保护模块3与断路器极2拼接后，使断路器可以正常接线使用，这种结构可以节省断路器的内部空间。
进一步的，引出导电件45设有弹性的接插部451，在第一壳体11的至少一端设有接线端子，在第一壳体11的一侧侧壁设置有两个第一接线口111，每个接插部451设置有插槽，每个接插部451与一个第一接线口111相对应，也就是每个接插部451位于第一壳体11内并与第一接线口111相对，优选每个接插部451的插槽对应伸入一个第一接线口111内，在第二壳体12的一侧侧壁设置有两个第二接线口，两个接线片分别对应穿过第二接线口121形成接插片44并对应与两个接插部451插拔连接，优选插槽可以依次穿过第一接线口111、第二接线口121与接线片的接插片44插接，当然，接线片依次穿过第二接线口121、第一接线口111与插槽插接也同样可以。
进一步的，接线片和/或引出导电件45对应穿过零序互感器34的穿线孔，优选第一接线口111、第二接线口121与零序互感器34的穿线孔相对应，此时第一接线口111、第二接线口121分别位于第一壳体11、第二壳体12的侧壁中部，如此可以缩短接线片和引出导电件45的长度以及减少其占用空间，如此，优选引出导电件45就近连接在设置于L极、N极中部的部件，例如触头机构的静触头、短路保护机构等，在本实施例中，短路保护机构位于第一壳体11的中部，零序互感器34位于第二壳体12的中部，短路保护机构与零序互感34相对应，优选L极的引出导电件45连接在短路保护机构，N极的引出导电件45连接在N极的触头机构，即所述第一接线口111位于外壳侧壁与短路保护机构对应的位置，或与静触头对应的位置，第二接线口121位于第二壳体12的侧壁与零序互感器34的穿线孔相对的位置，同时第一接线口111与第二接线口121对应，第一接线口111也与零序互感器34对应，如此设置，可以缩短引出导电件45和接线片的长度，利于插接配合。
相应的，漏电保护模块3的漏电测试回路从主回路取电，优选由第二弹性件32作为漏电测试回路的一个取电端与L极出线端子41-1b电连接，使得漏电测试回路可以从L相主线路取电，漏电测试回路的另一个取电端通过直接或间接与N极出线端子41-2b电连接取电，第一弹性件31的第一端与零序互感器34连接，第一弹性件31的第二端与第一弹性件31的第二端配合形成断点，如此，第二弹性件32既可以形成漏电测试回路的断点，也可以用于为漏电测试回路取 电，利于减少导线的使用数量。另外，漏电流检测电路中的线路板35也通过第二弹性件32取电，在线路板35上还连接有第三弹性件33，第三弹性件33的第二端作为线路板35的一个取电端与第二接线片43连接，由此，线路板35在实现从主回路取电的同时，也可以减少取电导线数目，提高了空间利用率，利于缩小体积。
进一步的，漏电保护模块3中的零序互感器34的接线端采用插针，如此可以通过插拔连接实现零序互感器34的接线，相比现有采用导线取电的方式，具备接线方便以及使用导线数目少的优点。
