Abstract

一种断路器用的接线装置及其断路器，包括：接线座（1），具有沿高度方向分布的多个母排插槽（11）；多个接线母排（2），与多个母排插槽（11）对应插接，接线母排（2）具有沿竖向设置的第一母排部（21）；多个第一导电件（3），沿宽度方向间隔布置于接线座（1）上，第一导电件（3）具有沿竖向设置的第一连接板（31）；第一紧固结构（5），将第一母排部（21）和第一连接板（31）固定连接。由于多个第一连接板（31）沿宽度方向竖向错位布置，这样沿高度方向布置的多个第一母排部（21）可直接与对应的第一连接板（31）连接，结构更加简单；而每一层的第一母排部（21）和第一连接板（31）均采用竖向布置的方式，这样大大减小了断路器用的接线装置的长度，与现有技术相比，产品更加小型化，另外，由于铜材用量小，不仅产品的温升更低，成本也更低。

本申请还提供一种断路器，包括断路器本体，以及如上所述的断路器用的接线装置。
本申请技术方案，具有如下优点：
1.本申请提供的断路器用的接线装置，包括接线座、接线母排、第一导电件、第一紧固结构，接线母排具有沿竖向设置的第一母排部，多个第一导电件沿宽度方向间隔布置于接线座上，第一导电件具有沿竖向设置的第一连接板。由于多个第一连接板沿宽度方向竖向错位布置，这样沿高度方向布置的多个第一母排部可直接与对应的第一连接板连接，结构更加简单；而每一层的第一母排部和第一连接板均采用竖向布置的方式，这样大大减小了断路器用的接线装置的长度，与现有技术采用支架、夹持件和驱动结构固定母排的方式相比，产品更加小型化，另外，由于铜材用量小，不仅产品的温升更低，成本也更低，还具有低能耗的优点，更加节能。
2.本申请提供的断路器用的接线装置，第一导电件具有与第一连接板底部一体弯折连接、可与断路器本体内部控制电路电连接的第二连接板，多个第二连接板均位于同一水平面，也即第一导电件呈L形设置，结构简单，加工方便，另外，由于多个第二连接板均位于同一水平面，从而方便与现有塑壳断路器的多个接线端子对应直接连接，或方便直接与断路器本体内部的控制电路相连。
3.本申请提供的断路器用的接线装置，第二导电件适于将对应设置的接线母排，与非对应的其余第一导电件错开设置，从而避免不同相之间的接线母排与非对应的第一导电件搭接形成短路，安全可靠性高。
4.本申请提供的断路器用的接线装置，多个第一母排部均设于第一竖直平面上，多个第二导电件均设于第二竖直平面上，多个第一连接板均设于第三竖直平面上，这样每一层由第 一母排部、第二导电件和第一连接板形成的组件的宽度不仅相同，且每一层组件的左右位置也相同，从而使得断路器用的接线装置的整体长度能够达到最小。
5.本申请提供的断路器用的接线装置，多个第一连接板的一部分朝下设置，另一部分朝上设置，这样使得多个第一连接板的总高度可以设置的较小，也即铜耗材量也小，从而更加节能，具有低能耗的优点。
6.本申请提供的断路器用的接线装置，接线母排具有与第一母排部垂直设置的第二母排部，也即接线母排呈L形，与现有技术接线母排采用平板状的方式相比，这样厂家可以根据客户对不同电流等级电器产品的需求，通过改变L形接线母排截面积的大小，改变载流能力，从而适用于不同电流等级的电器产品，也即当电流较小时，可仅采用竖向设置的第一母排部，而当电流较大时，可采用L形的接线母排，L形的接线母排也能够增加散热面积，散热效果更好。
7.本申请提供的断路器用的接线装置，接线座沿第一螺栓插入方向依次设有用于安装第二导电件的安装孔、用于安装第一连接板的第一通道、用于安装固定板的安装槽，第二导电件、第一连接板、固定板通过第二紧固结构固定连接，这样可以在出厂前就把第二导电件、第一连接板、固定板组装在一起，客户仅需将接线母排组装好即可，使用更加方便。
8.本申请提供的断路器用的接线装置，第二导电件一体成型于第一母排部或第一连接板上，这样结构更加简单，方便装配。
9.本申请提供的断路器用的接线装置，接线座与断路器本体之间设有连通外界与第二连接板的第二通道，从而利于第一导电件的散热，提高了安全可靠性。

实施例
本实施例提供一种断路器，如图1、2所示，包括断路器本体8，以及设于断路器本体8一侧的接线装置，其中，断路器用的接线装置包括接线座1、接线母排2、第一导电件3、第二导电件4、第一紧固结构5和第二紧固结构7。
接线座1，如图2所示，具有沿高度方向均匀分布的四个母排插槽11，所述接线座1从左至右依次设有用于安装所述第二导电件4的安装孔、用于安装所述第一连接板31的第一通道、用于安装所述固定板6的安装槽，所述接线座1与断路器本体8之间设有连通外界与所述第二连接板32的第二通道12。本实施例中，接线座1一体成型于断路器本体8上。
接线母排2，有四个，可与对应的母排插槽11对应插接，接线母排2具有沿竖向设置的第一母排部21，以及与所述第一母排部21垂直设置的第二母排部22，第二母排部22与母排插槽11底部的安装板相抵，四个所述第一母排部21均设于第一竖直平面上，需要说明的是，同一竖直平面指示的是四个所述第一母排部21的厚度均相同，且每一个第一母排部21的左右侧面的位置均对应相同。
第一导电件3，有四个，沿宽度方向均匀布置于接线座1上，第一导电件3为L形，其 具有沿竖向设置的第一连接板31，以及与所述第一连接板31底部一体弯折连接、可与断路器本体8内部控制电路电连接的第二连接板32，四个所述第一连接板31均设于第三竖直平面上，且均朝上设置，四个所述第二连接板32均均朝同一侧方向延伸，且均位于同一水平面上。
第二导电件4，有四个，如图3-5所示，其设于对应的所述第一母排部21和所述第一连接板31之间，所述第二导电件4适于将与其对应的所述接线母排2，与非对应的其余所述第一导电件3错开设置。本实施例中，四个所述第二导电件4均设于第二竖直平面上。如图3和4所示，以最底层的接线母排为例说明，由于四个第一连接板(31a、31b、31c、31d)均设于第三竖直平面上，为了避免第一母排部21a在与第一连接板31a接触的同时，与其他第一连接板(31b、31c、31d)搭接，通过设置第二导电件4，使得接线母排2与其他第一连接板(31b、31c、31d)搭接之间具有间隙，避免出现短路的情况。
如图6所示，所述第一紧固结构5包括：第一穿孔51，设于所述第一母排部21上；第二穿孔52，设于所述第二导电件4上，与所述第一穿孔51相对设置；第三穿孔53，设于所述第一连接板31上，与所述第二穿孔52相对设置；第一螺纹孔54，设于固定板6上，与所述第三穿孔53相对设置；第一螺栓，依次穿过所述第一穿孔51、所述第二穿孔52、所述第三穿孔53、所述第一螺纹孔54后，将所述第一母排部21、所述第二导电件4、第一连接板31、所述固定板6固定连接。需要说明的是，也可直接在第一连接板31上加工出螺纹孔，从而省去固定板6。
所述第二导电件4、所述第一连接板31、所述固定板6通过第二紧固结构7固定连接，如图6所示，所述第二紧固结构7包括：第四穿孔71，设于所述第二导电件4上；第五穿孔72，设于所述第一连接板31上，与所述第四穿孔71相对设置；第二螺纹孔73，设于所述固定板6上，与所述第五穿孔72相对设置；第二螺栓，依次穿过所述第四穿孔71、所述第五穿孔72后，与所述第二螺纹孔73螺纹连接。装配时，先将固定板6安装在安装槽内，再将第一导电件3的第一连接板31插入第一通道，最后将第二导电件4插入至安装孔内，通过第二紧固结构将第二导电件4、第一连接板31和固定板6固定连接。
作为可变换的实施方式，如图11所示，四个所述第一连接板31均朝下设置。
作为可变换的实施方式，如图12和13所示，四个所述第一连接板31的其中两个朝下设置，另外两个朝上设置，这样能够降低四个第一母排部的总高度，从而铜耗材量也小，一 方面降低了生产成本，另一方面也更加节能，具有低能耗的优点。
作为可变换的实施方式，如图7所示，四个所述第一连接板31均设于第三竖直平面上，四个第二导电件4的长度从上至下逐渐增大。
作为可变换的实施方式，如图8和9所示，多个接线母排2呈阶梯式排布，且每一层仅由接线母排2、第一导电件3和固定板6组成。
作为可变换的实施方式，如图10所示，第二导电件4可一体成型于所述第一母排部21或所述第一连接板31上，也即第二导电件4可焊接或铆接与第一母排部21上；第二导电件4和第一导电件3可直接由同一板材冲压成型，或第二导电件4与第一导电件3一体弯折连接。
作为可变换的实施方式，第一紧固结构和第二紧固结构可以为铆钉或焊接连接。
作为可变换的实施方式，接线座1与断路器本体8分体设置。
作为可变换的实施方式，接线装置可同时与2个、3个、4个或者更多的断路器连接。
需要说明的是，本申请的接线装置也可用于接触器、熔断器等配电电器。
本申请提供的断路器用的接线装置，包括接线座1、接线母排2、第一导电件3、第一紧固结构5，接线母排2具有沿竖向设置的第一母排部21，多个第一导电件3沿宽度方向间隔布置于接线座1上，第一导电件3具有沿竖向设置的第一连接板31。由于多个第一连接板31沿宽度方向竖向错位布置，这样沿高度方向布置的多个第一母排部21可直接与对应的第一连接板31连接，结构更加简单；而每一层的第一母排部21和第一连接板31均采用竖向布置的方式，这样大大减小了断路器用的接线装置的长度，与现有技术采用支架、夹持件和驱动结构固定母排的方式相比，产品更加小型化，另外，由于铜材用量小，不仅产品的温升更低，成本也更低。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
