具体实施方式
下面结合附图对本发明实施例作进一步说明:
如图1和图3所示,一种小型断路器,其包括:外壳1、电磁脱扣装置、过载脱扣装置以及手柄2,其提供一种手动操作所述小型断路器至分闸位置或合闸位置的方式;U型连杆3,其一端连接到所述手柄2;跳扣4,其连接到所述U型连杆3的另一端,并通过由所述U型连杆3传输的机械力摆动;
固定接触器5,其电连接到电源或者电力电路的负载;活动接触器6,其摆动至所述固定接触器5的位置或与所述固定接触器5分开的位置以便闭合或断开所述电路,所述活动接触器6的一端连接到所述跳扣4以便与所述跳扣4构成联动配合;铰接轴7,贯穿活动接触器6后套接在设置在外壳上的轴套12上,三者相适配后,被构成为在所述活动接触器6摆动以闭合或断开电路且在所述活动接触器6不与所述固定接触器5接触的期间,提供摆动的支点;
储能弹簧8,在所述小型断路器分闸过程中,提供活动接触器6沿铰接轴7摆动以 断开
所述电路的回复力;所述活动接触器6包括锁扣61、支架62和动触头63,所述支架62通过铰接轴7定位在 外壳1上
,设有第一铰接轴621,跳扣4套接在第一铰接轴621上,并以该铰接轴为中心,周向摆动;支架上第二铰接轴622,锁扣61套接在第二铰接轴622上,锁扣61具有一个与跳扣4接触时构成互锁结构的伸出部611,和一个与凸台627接触时构成第一限位结构的凸展部612,锁扣61上设有复位件,具有驱动锁扣61向凸台627方向摆动的回复力;动触头63与支架62构成联动配合,由支架62带动动触头63沿铰接轴7摆动,该小型断路器的分合闸结构由跳扣4、锁扣61和支架62作为主要构成部分,在装配时,可以先将三者套接好,再装入小型断路器中,也可以将支架62、锁扣61、跳扣4依次直接装入小型断路器中,不管采用哪种安装方式,都是通过套接即可实现两者之间的连接,安装非常方便;进一步的,仅仅采用跳扣4、锁扣61和支架62,无需多余部件来实现这三者之间的连接,使得结构更加紧凑和简单。
所述铰接轴7 贯穿凸台627 后套接在设置在外壳1上的轴套12上,三者相适配 ,如此使得,凸台627 与
铰接轴7
之间的是同心轴配合,配合的相对最为稳定,当然在必要的情况下,也可以设置成偏心轴,即铰接轴7只要贯穿支架62可以实现以铰接轴7为支点,带动支架62的摆动即可,此时凸台627仅仅用作
限位结构的一部分 。
如图1和图6所示,在所述小型断路器至合闸过程中,手柄2摆动,通过U型连杆3带动跳扣4逆时针摆动,由于跳扣4与锁扣61的伸出部611是互锁的,所以跳扣4摆动的同时,带动锁扣61顺时针摆动,当锁扣61摆动到达锁扣61的凸展部612与凸台627接触的位置时,锁扣61继续摆动,带动凸台627旋转,又由于凸台627是设置在支架62上的,所以带动支架62摆动,由于
动触头63与支架62之间构成顺时针摆动时的锁止结构,所以 支架62可以带动动触头63摆动,最终使得动触头63与 固定接触器5
接触,小型断路器合闸得电。
如图5和图7所示, 在支架62设有 第三铰接轴623, 所述动触头63 套接在第三铰接轴623上,
在第三铰接轴623上套设第二扭簧624,第二扭簧624一端抵着 凸台627
,一端连接动触头63,为了使第二扭簧624固定的更加稳固,在凸台627上设置用于卡嵌第二扭簧624的 凹槽,
当小型断路器合闸时,即动触头63与固定接触器5相接触时,该第二扭簧624使得支架62可以相对动触头63顺时针摆动一定位置,以使得动触头63与固定接触器5贴合的更加紧密,也就是说,使得动触头63具有一定的超程;而在小型断路器分闸时,第二扭簧624的弹力会使得动触头63回复至动触头63与支架62的起始配合位置。
如图1所示,在所述小型断路器分闸过程中,手柄2摆动,通过U型连杆3带动跳扣4顺时针摆动,此时跳扣4与锁扣61解锁,
一端抵着外壳1,另一端抵着在支架62侧壁的凸块626上的 储能弹簧8
释放弹力,使得支架62做逆时针摆动,支架62带动动触头63摆动,最终使得动触头63与固定接触器5分离, 小型
断路器分闸失电,在分闸过程中,支架62摆动到凸台627与 锁扣61的凸展部612接触的位置时,
支架62继续摆动,带动锁扣61随支架62同步摆动,即回复到初始状态 。
如图4所示,在支架62表面设有一段弧槽625,该弧槽625与 U 型连杆3
贯穿跳扣4的该端相适配,在小型断路器分闸时, U
型连杆3带动跳扣4顺时针摆动,而该弧槽625的设置是作为对U型连杆3的一种限位,限制了U型连杆3带动跳扣4过渡摆动,而导致跳扣4不能回位,该弧的末端是U型连杆3位移的限位位置,且此时跳扣4与锁扣61又已经处于解锁状态
。
所述 复位件 一端置于
设在锁扣61上表面的卡槽614中,另一端卡置在锁扣61摆动时与锁扣61存在相对位移的部件上的第一扭簧613,该第一扭簧613具有一个弹力,具有一个弹力,该弹力恒作用在锁扣61上,使得锁扣61在不受其他力作用下一直处于锁扣61的凸展部612与凸台627接触的位置,一方面,在小型断路器合闸状态下,锁扣61在该弹力作用下,而跳扣4在U型连杆3作用下,锁扣61与跳扣4之间的互锁更加的稳固,防止被意外解锁;另一方面,在小型断路器分闸过程中,刚开始解锁的一瞬间,锁扣61的凸展部612与凸台627会有一个瞬间的不接触状态,但随即锁扣61在该弹力作用下,马上回到锁扣61的凸展部612与凸台627接触的位置,并随支架62摆动,为下一次的小型断路器合闸做准备。
如图3所示,为了方便固定,所述部件 表面 开设
一字槽6221,该一字槽6221可以设置在小型断路器内任何一个固定的部件上,只要该部件在锁扣61摆动时与锁扣61存在相对位移设置即可,优选的,将一字槽6221设置在第二铰接轴622的端表面,尤其第二铰接轴622设置在支架62上的情况下,使得锁扣61和支架62之间的结构更加紧凑,一字槽6221的加工更加方便,第一扭簧613的装配也更加方便。
如图1所示,在小型断路器中均会设置过载脱扣保护和短路脱扣保护,其中过载脱扣是通过双金片100来实现的,短路脱扣是通过电磁线圈91来实现的。
所述过载脱扣装置包括双金片100和弯连杆101,所述弯连杆101一端可活动的插接在设置在
锁扣61上第二插接孔617中,另一端置于双金片100一侧,只有当小型断路器处于过载状态时,双金片100过热发生形变,与弯连杆101接触,并带动弯连杆101,使弯连杆101沿逆时针摆动,由于弯连杆101是插接在锁扣61上的,此时会带动锁扣61摆动,从而实现锁扣61与跳扣4的瞬态解锁,而后在储能弹簧8的作用下,使得支架62沿逆时针摆动,并带动跳扣4摆动,最终带动U型连杆4摆动,手柄2至分闸位置,小型断路器处于分闸状态,以保护小型断路器
不损坏 。
所述电磁脱扣装置包括电磁线圈91、置于电磁线圈91中的顶杆92以及设置在锁扣
上的平面部616,所述顶杆92与平面部616构成分闸位置,两者不接触的第一状态,和合闸位置,两者相接触的第二状态;当小型断路器处于短路状态时,电磁线圈91得电,使得置于电磁线圈91中的顶杆92弹出,由于顶杆92与平面部616本来就是接触的,所以顶杆92弹出会顶着平面部616做逆时针旋转,从而实现锁扣61与跳扣4的瞬态解锁,而后在储能弹簧8的作用下,使得支架62沿逆时针摆动,并带动跳扣4摆动,最终带动U型连杆4摆动,手柄2至分闸位置,小型断路器处于分闸状态,以保护小型断路器
不损坏 。
在 过载脱扣和电磁脱扣过程中,除了储能弹簧8对支架62的一个作用力外,所述
锁扣61的伸出部611会与凸台627接触时,二者构成第二限位结构,使得锁扣61的摆动也会产生作用在凸台627上的一个力,来带动支架62做逆时针的摆动,该力与
储能弹簧8的作用力共同作用,能缩短小型断路器的分闸时间,加快小型断路器的分闸过程,从而及时保护小型断路器不损坏
,同时,在完成分闸过程以后,支架62不再受到之前的2个作用力,此时第一扭簧613的弹力起主要作用,使锁扣61顺时针摆动至锁扣61的凸展部612与凸台627接触的位置,为下一次的合闸做准备。
所述
第一铰接轴621、第二铰接轴622和第三铰接轴623分别用于跳扣4与支架62、锁扣61与支架62、动触头 63
与支架62之间的连接,这3个铰接轴可以是直接设置在外壳1上,装配时,直接将跳扣4、锁扣61和支架62按顺序安装到外壳1上即可,优选的,将这3个铰接轴设置在支架62上,可以更好的实现跳扣4与支架62、锁扣61与支架62、动触头
63 与支架62在摆动时的相互配合,当然,设置在支架62上,可以使得整体结构更加紧凑,加工也更加方便。
如图2所示,所述外壳1上设有供锁扣61上的第一插接孔615与其他部件比如两个小型断路器之间连接以构成联动配合的弧形通槽11,以满足实现其他功能。
以上结合附图所描述的实施例仅是本发明的优选实施方式,而并非对本发明的保护范围的限定,任何基于本发明精神所做的改进都理应在本发明保护范围之内。
