Description
本申请涉及配电设备技术领域,尤其涉及一种底座、带底座的断路器和配电设备。
断路器作为线路过载或者短路故障保护器件,因其较保险丝具有可恢复重复使用的优点,而广泛应用于各类电路中。
为了便于多个电路的断路器的统一管理,通常将该多个电路的断路器集中安装在一个配电设备内,并通过一个导轨串接排布成一排,或者通过平行设置的多个导轨串接排布成多排。这些断路器在进行电流规格的升级时,不仅需要更换断路器,还需要更换该断路器所连接的线缆和接线端子,因此断路器的升级难度和成本较高。为了解决此问题,可以在配电设备中的导轨上安装能够兼容多种电流规格的断路器的底座,该底座连接的线缆和接线端子能够传输多种规格的电流,并将断路器可拆卸连接于该底座上。这样,只需要从该底座上拆卸并更换断路器即可实现断路器的升级,因此断路器的升级操作简单,便于管理。但是,由于针对每个断路器均设计了至少一个底座,配电设备中的断路器的数量较多,相应的底座的数量也较多,使得成本大幅度增加。
发明内容
本申请提供一种底座、带底座的断路器和配电设备,能够降低底座的成本。
为达到上述目的,本申请的实施例采用如下技术方案:
第一方面,本申请一些实施例提供一种底座,该底座包括绝缘壳体,该绝缘壳体具有相背离的第一表面和第二表面,第一表面用于可拆卸连接断路器,第二表面设有第一安装卡槽,绝缘壳体能够通过该第一安装卡槽可滑动卡接于配电设备内的安装导轨上,绝缘壳体内设有容纳腔,该容纳腔用于容纳导电连接件,容纳腔沿绝缘壳体相对于安装导轨的滑动方向上的一端开口,另一端封闭。
在将多个本申请实施例提供的底座安装于安装导轨上时,多个底座的容纳腔的开口的朝向相同,且每相邻两个底座中,一个底座的第一壁板封堵另一个底座的容纳腔的开口,由此实现了相邻两个底座的导电连接件之间的绝缘隔离。因此,底座的绝缘壳体无需设计成封闭的壳体,绝缘壳体的用料成本较低,底座的成本较低,在安装有较多数量的底座的配电设备中,可以大幅度节省成本。
可选地,绝缘壳体包括底臂部和两个侧臂部,两个侧臂部的一端分别连接于底臂部沿第一方向的两端,两个侧臂部的另一端沿第二方向向底臂部的同一侧延伸,底臂部与两个侧臂部围成第二安装卡槽,第二安装卡槽用于配合卡接断路器;第二安装卡槽的内表面和侧臂部的远离底臂部的表面构成绝缘壳体的第一表面,底臂部的背离第二安装卡槽的表面构成第二表面,绝缘壳体相对于安装导轨的滑动方向、第一方向、第二方向两两垂直。这样,可以将断路器由第二安装卡槽的远离底臂部的一端开口可拆卸卡接于第二安装卡槽内,断路器的卡接操作简单,安装拆卸效率较高。
可选地,绝缘壳体上设有第一连接口和第二连接口,第一连接口和第二连接口均 与容纳腔连通,第一连接口用于在断路器连接至第一表面时,允许断路器的端子伸入容纳腔,第二连接口允许线缆端子伸入容纳腔;底座还包括导电连接件,该导电连接件设置于容纳腔内,且导电连接件包括电连接的第一导电连接部和第二导电连接部,第一导电连接部靠近所述第一连接口设置,第一导电连接部用于与断路器的端子电连接,第二导电连接部靠近第二连接口设置,第二导电连接部用于与线缆端子电连接。由此,能够实现断路器与线缆之间的电连接。
可选地,第一导电连接部为U型导电弹片,U型导电弹片的两个弹性臂之间形成插槽,插槽用于在断路器连接至第一表面时,与断路器的端子配合插接。这样,第一导电连接部与断路器的端子之间通过插接的方式实现电连接,电连接的稳定性较优。
可选地,U型导电弹片的弹性臂的围成插槽的开口的一端边沿设有至少一个缺口,该至少一个缺口向插槽的底壁延伸,以将弹性臂分隔为多个弹性臂单元,弹性臂单元包括抵触部,该抵触部为在断路器的端子插入插槽的过程中与断路器的端子接触的部分,多个弹性臂单元的抵触部与插槽的底壁之间在插槽的深度方向上的距离不同。这样,将弹性臂分割为多个抵触部相互独立的弹性臂单元,并使多个弹性臂单元的抵触部在断路器插入的过程中与断路器的端子的接触时间不同,以在底座处于通电状态下插入断路器的过程中,使得电弧产生在最先接触的弹性臂单元上,由此牺牲掉该弹性臂单元的电性能,以使断路器的端子在插入插槽之后能够与其余的弹性臂单元进行有效电连接。由此避免U型导电弹片的弹性臂在端子插入过程中因电弧而全部被牺牲掉。
可选地,底座还包括U型固定套,该U型固定套由塑料或者金属制成,且该U型固定套具有弹性。U型固定套套设于U型导电弹片外,以固定U型导电弹片的多个弹性臂单元之间的相对位置,增大U型导电弹片的两个弹性臂之间的弹性夹紧力,以使U型导电弹片与断路器的端子能够有效接触并电连接。
可选地,容纳腔中靠近第二连接口的位置设有线缆端子插接槽,该线缆端子插接槽的开口与第二连接口相对;第二导电连接部构成线缆端子插接槽的一个侧壁;底座还包括弹性件,该弹性件构成线缆端子插接槽的与第二导电连接部相对的另一个侧壁,弹性件用于当线缆端子穿过第二连接口插入线缆端子插接槽内时,向线缆端子施加指向第二导电连接部的弹性压紧力,以将线缆端子压接于第二导电连接部上。这样,线缆端子在插入线缆端子插接槽内,即可实现与第二导电连接部之间的电连接和相对位置固定,此连接方式操作方便,效率较高。且通过设计弹性件的弹性力,可以保证线缆端子与第二导电连接部之间连接的稳固性,防止线缆端子脱落。
可选地,弹性件为弹片,该弹片包括固定部和弹臂部,固定部与绝缘壳体相对固定,弹臂部的一端与固定部连接,弹臂部的另一端向靠近第二导电连接部的方向延伸并向远离第二连接口的方向倾斜,弹臂部构成线缆端子插接槽的与第二导电连接部相对的另一个侧壁。这样,在线缆端子穿过第二连接口插入线缆端子插接槽的过程中,线缆端子的头部挤压弹臂部,以使弹臂部产生弯曲变形,并积蓄弹性力,该弹性力指向第二导电连接部。当弹臂部产生的弯曲变形达到一定程度时,积蓄的弹性力能够将线缆端子压接于第二导电连接部上,以实现线缆端子与第二导电连接部之间的电连接和相对位置固定。此结构简单,容易实现。
可选地,底座还包括解锁装置,该解锁装置用于驱动弹臂部向远离第二导电连接 部的方向运动,以取消施加于线缆端子上的弹性压紧力。这样,在线缆与底座之间的安装过程出现错误时或者在后期底座的维护过程中,可以通过解锁装置驱动弹臂部向远离第二导电连接部的方向运动,以取消施加于线缆端子上的弹性压紧力,并由线缆端子插接槽内拔出线缆端子,以实现线缆端子在底座上的拆卸。

下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。
在本申请实施例中,术语“第一”、“第二”、“第三”、“第四”、“第五”、“第六”、“第七”、“第八”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”、“第三”、“第四”、“第五”、“第六”、“第七”、“第八”的特征可以明示或者隐含地包括一个或者更多个该特征。
在本申请的描述中,“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
本申请涉及底座、带底座的断路器和配电设备,以下对本申请涉及到的概念进行简单说明:
微型断路器(micro circuit breaker/miniature circuit breaker,MCB):是建筑电气 终端配电装置中使用最广泛的一种终端保护电器。用于电流为125A以下的单相或三相的短路、过载、过压等保护,微型断路器包括单极(也即是1P)、二极(也即是2P)、三极(也即是3P)、四极(也即是4P)等四种。
铜排:又称铜母排或铜汇流排,是由铜材质制作的,截面为矩形或具有倒角或者倒圆角的矩形的长导体,为了避免产生尖端放电,目前一般都用截面为倒圆角的矩形的铜排,铜排在电路中起输送电流和连接电气设备的作用。
负温度系数(negative temperature coefficient,NTC)热敏电阻:是一种电阻值随着温度上升而迅速下降的热敏电阻。它是以锰、钴、镍和铜等金属的氧化物为主要材料,采用陶瓷工艺制造而成的。
断路器的底座通常包括封闭的绝缘壳体和导电连接件。断路器安装于绝缘壳体上,导电连接件设置于绝缘壳体内,导电连接件的一端与断路器的端子电连接,导电连接件的另一端与线缆端子电连接,线缆端子连接有线缆,以实现断路器与线缆的连接。在将多个断路器的底座串接在配电设备中的导轨上时,相邻两个底座紧靠在一起,相邻两个底座的导电连接件之间通过该相邻两个底座的绝缘壳体隔开,而实际上该相邻两个底座的导电连接件之间采用一个底座的绝缘壳体隔开,即可实现该两个底座的导电连接件之间的绝缘隔离,因此底座的绝缘壳体的用料存在多余,从而造成了资源浪费。
为了避免上述问题,本申请提供了一种配电设备,该配电设备包括但不限于高压配电柜、低压开关柜、开关箱、控制箱等。
图1为本申请一些实施例提供的配电设备的结构示意图。如图1所示,配电设备包括断路器容纳腔1,该断路器容纳腔1内设有安装导轨2和多个带底座的断路器3,多个带底座的断路器3分别通过底座31可滑动卡接于安装导轨2上,以通过安装导轨2将多个带底座的断路器3串接成一排,以便于断路器的管理。容纳腔1的一端开口,容纳腔1的开口处设有盖体4,该盖体4用于打开或关闭该容纳腔1,以便于操作人员执行开启、关断、维修断路器的操作。
本申请还提供一种带底座的断路器,该带底座的断路器为上述配电设备中的带底座的断路器。带底座的断路器包括断路器和底座。可选地,断路器为微型断路器。断路器可以为单极断路器、二极断路器、三极断路器或者四极断路器,在此不做具体限定。断路器安装于底座上,底座安装于配电设备内的安装导轨上,并可沿安装导轨滑动,以调节带底座的断路器的位置。
其中,带底座的断路器中底座的数量可以为一个、两个、三个、四个,在此不做具体限定。由于断路器可以为单极断路器、二极断路器、三极断路器或者四极断路器,二极断路器在安装导轨的延伸方向上的宽度通常是单极断路器在安装导轨的延伸方向上的宽度的两倍,三极断路器在安装导轨的延伸方向上的宽度通常是单极断路器在安装导轨的延伸方向上的宽度的三倍,四极断路器在安装导轨的延伸方向上的宽度通常是单极断路器在安装导轨的延伸方向上的宽度的四倍,因此为了提高底座的适配灵活性,底座可以为匹配单极断路器的底座,这样,若断路器为二极断路器,则采用并排布置的两个底座即可安装该二极断路器;若断路器为三极断路器,则采用并排布置的三个底座即可安装该三极断路器;若断路器为四极断路器,则采用并排布置的四个底 座即可安装该四极断路器。
图2为本申请一些实施例提供的带底座的断路器的结构示意图。如图2所示,带底座的断路器包括断路器31和底座32。断路器31为单极的微型断路器,底座32适配单极断路器,断路器31安装于底座32上,底座32安装于配电设备内的安装导轨上。图3为多个图2所示带底座的断路器安装于安装导轨上的结构示意图。如图3所示,多个带底座的断路器3可沿安装导轨2滑动,以调节多个带底座的断路器3的位置。
图4为本申请另一些实施例提供的带底座的断路器的结构示意图。如图4所示,带底座的断路器包括断路器31和底座32。断路器31为二极的微型断路器,底座32的数量为两个,每个底座32适配单极断路器。两个底座32并排布置,断路器31安装于该并排布置的两个底座32上,两个底座32安装于配电设备内的安装导轨2上,并可沿安装导轨2滑动,以调节该带底座的断路器3的位置。
本申请还提供了一种底座,该底座为上述带底座的断路器中的底座。图5为本申请一些实施例提供的底座处于第一方位时的结构示意图,该底座为图2或图4所示带底座的断路器中的底座32。
如图5所示,底座32包括绝缘壳体321,该绝缘壳体321由塑胶、陶瓷等绝缘材料制作。
绝缘壳体321具有相背离的第一表面100和第二表面200。第一表面100可以为平面,也可以为曲面,第一表面100用于可拆卸连接断路器31。第二表面200可以为平面,也可以为曲面,第二表面200设有第一安装卡槽300,绝缘壳体321能够通过第一安装卡槽300可滑动卡接于配电设备内的安装导轨2上。
如图5所示,绝缘壳体321内形成容纳腔400,容纳腔400用于容纳导电连接件322。容纳腔400沿绝缘壳体321相对于安装导轨2的滑动方向(也即是图5所示的方向X)上的一端开口,另一端通过绝缘壳体321的第一壁板321c封闭。
这样,在将多个底座32安装于安装导轨2上时,图6为多个图5所示底座在安装于安装导轨上且相邻两个底座之间拉开一定距离时的结构示意图,在实际使用时,该多个底座依次贴合在一起。如图6所示,多个底座32的容纳腔400的开口的朝向相同,且每相邻两个底座32中,一个底座32的第一壁板321c封堵另一个底座32的容纳腔400的开口,由此实现了相邻两个底座32的导电连接件322之间的绝缘隔离。因此,底座32的绝缘壳体321无需设计成封闭的壳体,绝缘壳体321的用料成本较低,底座32的成本较低,在安装有较多数量的底座的配电设备中,可以大幅度节省成本。
在上述实施例中,为了保护位于端部的底座32内的导电连接件322,如图6所示,在位于端部的底座32的容纳腔400的开口处盖设有盖板500,通过该盖板500能够封堵位于端部的底座32的容纳腔400的开口。
第一表面100可以通过卡接、螺纹连接、磁吸等方式可拆卸连接断路器31,在此不做具体限定。
在一些实施例中,如图5所示,绝缘壳体321包括底臂部3211和两个侧臂部3212。两个侧臂部3212的一端分别连接于底臂部3211沿第一方向(也即是图5所示的方向Y)的两端,两个侧臂部3212的另一端沿第二方向(也即是图5所示的方向Z)向底臂部3211的同一侧延伸。
如图5所示,底臂部3211与两个侧臂部3212围成第二安装卡槽600,该第二安装卡槽600用于配合卡接断路器31。第二安装卡槽600的内表面和侧臂部3212的远离底臂部3211的表面构成第一表面100,底臂部3211的背离第二安装卡槽600的表面构成第二表面200。
其中,绝缘壳体321相对于安装导轨2的滑动方向、第一方向、第二方向两两垂直。
这样,可以将断路器31由第二安装卡槽600的远离底臂部3211的一端开口可拆卸卡接于第二安装卡槽600内,断路器31的卡接操作简单,安装拆卸效率较高。
底座32用于实现断路器31与线缆之间的电连接,为了达到此目的,如图5所示,底座32还包括导电连接件322,该导电连接件322设置于容纳腔400内,该导电连接件322用于导电连接断路器31的端子和线缆端子。
具体地,如图5所示,绝缘壳体321上设有第一连接口321a,图7为图5所示底座处于第二方位时的结构示意图,如图7所示,绝缘壳体321上还设有第二连接口321b,该第一连接口321a和该第二连接口321b均与容纳腔400连通。第一连接口321a用于在断路器31连接至第一表面100时,允许断路器31的端子伸入容纳腔400,第二连接口321b允许线缆端子伸入容纳腔400。
导电连接件322包括电连接的第一导电连接部3221和第二导电连接部3222,第一导电连接部3221和第二导电连接部3222均由铜或铜的合金制成。第一导电连接部3221靠近第一连接口321a设置,第一导电连接部3221用于与断路器31的端子电连接。第二导电连接部3222靠近第二连接口321b设置,第二导电连接部3222用于与线缆端子电连接,线缆端子连接有线缆。
第一导电连接部3221与断路器31的端子之间的电连接方式可以为插接式电连接、抵接式电连接等等,在此不做具体限定。
图8为本申请一些实施例提供的带底座的断路器中断路器的结构示意图,该断路器为图2或图4所示带底座的断路器中的断路器31。如图8所示,断路器31包括断路器本体311和端子312。端子312为连接于断路器本体311的接线端子上的转接端子,该端子312可以为铜排或者其他金属导体结构。在一些实施例中,如图8所示,端子312为铜排。
具体地,图9为图8所示带底座的断路器中断路器的爆炸图。如图9所示,断路器本体311的侧壁上设有接线孔311a,接线孔311a内设有接线端子(图中未示出)。端子312包括固定部312a以及固定于该固定部312a上的插接部312b。固定部312a伸入接线孔311a内并与接线端子电连接,插接部312b凸设于断路器本体311的侧壁外。图10为图8所示断路器在安装至底座的第一表面时的结构示意图。如图10所示,在断路器连接至第一表面100时,端子312通过插接部312b与第一导电连接部3221配合插接,以实现端子312与第一导电连接部3221之间的电连接。
在另一些实施例中,若断路器本体311的接线端子凸出断路器本体311的表面设置,则端子312也可以为断路器本体311的接线端子,在此不做具体限定。
端子312的数量为两个,两个端子312分别为正极端子和负极端子,相应的,如图5所示,底座32包括的导电连接件322的数量也为两个,两个导电连接件322分别 用于实现正极端子与阳极线缆之间、负极端子与阴极线缆之间的电连接。
如图5所示,第一导电连接部3221为U型导电弹片,该U型导电弹片的两个弹性臂之间形成插槽700,插槽700用于在断路器连接至第一表面100时,与断路器的端子312配合插接。
这样,第一导电连接部3221与断路器31的端子312之间通过插接的方式实现电连接,电连接的稳定性较优。
在一些实施例中,U型导电弹片的弹性臂的围成插槽700的开口的一端边沿设有至少一个缺口,该至少一个缺口向插槽700的底壁延伸,以将弹性臂分隔为多个弹性臂单元。弹性臂单元包括抵触部,该抵触部为在断路器31的端子312插入插槽700的过程中与断路器31的端子312接触的部分,多个弹性臂单元的抵触部与插槽700的底壁之间在插槽700的深度方向上的距离不同。
示例的,图11为图5所示底座中的导电连接件的结构示意图,如图11所示,U型导电弹片的两个弹性臂中,每个弹性臂的围成插槽700的开口的一端边沿均设有两个缺口a,该两个缺口a向插槽700的底壁延伸,以将该弹性臂分隔为三个弹性臂单元3221a。三个弹性臂单元3221a中每个弹性臂单元3221a均包括抵触部b,三个弹性臂单元3221a中位于中间的一个弹性臂单元3221a的抵触部b与插槽700的底壁之间在插槽700的深度方向上的距离为第一距离,三个弹性臂单元3221a中位于两边的两个弹性臂单元3221a的抵触部b与插槽700的底壁之间在插槽700的深度方向上的距离相等,且均为第二距离,第一距离大于第二距离。
这样,将弹性臂分割为多个抵触部b相互独立的弹性臂单元3221a,并使多个弹性臂单元3221a的抵触部b在断路器31插入的过程中与断路器31的端子312的接触时间不同,以在底座32处于通电状态下插入断路器31的过程(也即是热插拔过程)中,使得电弧产生在最先接触的弹性臂单元3221a上,由此牺牲掉该弹性臂单元3221a的电性能,以使断路器31的端子312在插入插槽700之后能够与其余的弹性臂单元3221a进行有效电连接。由此避免U型导电弹片的弹性臂在端子312插入过程中因电弧而全部被牺牲掉。
为了固定多个弹性臂单元3221a之间的相对位置,在一些实施例中,图12为图5所示底座中的导电连接件与U型固定套之间的连接结构示意图。如图12所示,底座32还包括U型固定套323,该U型固定套323由塑料或者金属制成,且该U型固定套323具有弹性。U型固定套323套设于U型导电弹片外,以固定U型导电弹片的多个弹性臂单元3221a之间的相对位置,增大U型导电弹片的两个弹性臂之间的弹性夹紧力,以使U型导电弹片与断路器31的端子312能够有效接触并电连接。
第二导电连接部3222与线缆端子之间的电连接方式可以为插接式电连接、压接式电连接等等,在此不做具体限定。
在一些实施例中,图13为图5所示底座处于第三方位且去除挡板800时的结构示意图。如图13所示,容纳腔400中靠近第二连接口321b的位置设有线缆端子插接槽401,线缆端子插接槽401的开口与第二连接口321b相对。第二导电连接部3222构成线缆端子插接槽401的一个侧壁。在线缆端子穿过第二连接口321b插入线缆端子插接槽401内之后,线缆端子可以与第二导电连接部3222接触电连接。
如图13所示,底座32还包括弹性件324。弹性件324构成线缆端子插接槽401的与第二导电连接部3222相对的另一个侧壁。弹性件324用于当线缆端子穿过第二连接口321b插入该线缆端子插接槽401内时,向线缆端子施加指向第二导电连接部3222的弹性压紧力,以将该线缆端子压接于第二导电连接部3222上。
这样,线缆端子在插入线缆端子插接槽401内,即可实现与第二导电连接部3222之间的电连接和相对位置固定,此连接方式操作方便,效率较高。且通过设计弹性件324的弹性力,可以保证线缆端子与第二导电连接部3222之间连接的稳固性,防止线缆端子脱落。
如图5所示,底座32还包括挡板800,该挡板800和第一壁板321c构成线缆端子插接槽401的另外两个侧壁,由此限定了线缆端子的插接位置。
弹性件324包括但不限于弹簧、弹片和橡胶,图13仅给出了弹性件324为弹片的示例,并不能认为是对本申请构成的限定。当弹性件324为弹片时,具体地,如图13所示,弹片包括固定部3241和弹臂部3242。固定部3241与绝缘壳体321相对固定。弹臂部3242的一端与固定部3241连接,弹臂部3242的另一端向靠近第二导电连接部3222的方向延伸并向远离第二连接口321b的方向倾斜。弹臂部3242构成线缆端子插接槽401的与第二导电连接部3222相对的另一个侧壁。
这样,在线缆端子穿过第二连接口321b插入线缆端子插接槽401的过程中,线缆端子的头部挤压弹臂部3242,以使弹臂部3242产生弯曲变形,并积蓄弹性力,该弹性力指向第二导电连接部3222。当弹臂部3242产生的弯曲变形达到一定程度时,积蓄的弹性力能够将线缆端子压接于第二导电连接部3222上,以实现线缆端子与第二导电连接部3222之间的电连接和相对位置固定。此结构简单,容易实现。
在线缆与底座32之间的安装过程出现错误时或者在后期底座32的维护过程中,需要由底座32上拆卸线缆。为了便于线缆的拆卸,在一些实施例中,如图13所示,底座32还包括解锁装置325。该解锁装置325用于驱动弹臂部3242向远离第二导电连接部3222的方向运动,以取消施加于线缆端子上的弹性压紧力。
这样,在线缆与底座32之间的安装过程出现错误时或者在后期底座32的维护过程中,可以通过解锁装置325驱动弹臂部3242向远离第二导电连接部3222的方向运动,以取消施加于线缆端子上的弹性压紧力,并由线缆端子插接槽401内拔出线缆端子,以实现线缆端子在底座32上的拆卸。
解锁装置325的结构形式有多种,在此不做具体限定。
示例的,解锁装置325可以为连接于弹臂部3242上的拉绳,通过该拉绳可以拉动弹臂部3242向远离第二导电连接部3222的方向运动。
又示例的,如图13所示,解锁装置325包括顶杆3251。弹片还包括连接部3243,弹臂部3242的一端通过连接部3243与固定部3241连接。图14为图13所示底座的第二表面的结构示意图。如图14所示,第二连接口321b所处的绝缘壳体321的壁板上与连接部3243(参见图13)相对的位置设有滑孔321d。顶杆3251滑动穿设于该滑孔321d内,并能够向靠近连接部3243的方向滑动至第一位置(图中未示出),以挤压连接部3243向远离滑孔321d的方向弯曲,并带动弹臂部3242向远离第二导电连接部3222的方向运动,以取消施加于线缆端子的弹性压紧力。此解锁装置325的结构简单, 容易实现。
在上述实施例中,解锁装置325还包括第一锁止结构3252。该第一锁止结构3252用于在顶杆3251滑动至第一位置之后,固定顶杆3251与滑孔321d之间在滑孔321d的轴向上的相对位置。
这样,可以通过第一锁止结构3252将顶杆3251保持在第一位置,以使弹臂部3242保持在取消施加于线缆端子的弹性压紧力的位置,由此,操作人员无需手动保持顶杆3251,操作人员可以单手将线缆端子由线缆端子插接槽401内拔出,因此线缆的拆卸操作方便。
第一锁止结构3252的结构形式有多种,在此不做具体限定。
示例的,第一锁止结构3252包括弹性卡扣和弹性卡槽,弹性卡扣和弹性卡槽中的一个设置于顶杆3251上,弹性卡扣和弹性卡槽中的另一个设置于滑孔321d所处的绝缘壳体321的壁板上,当顶杆3251沿滑孔321d滑动至第一位置时,弹性卡扣卡接于弹性卡槽中,以固定顶杆3251与滑孔321d之间在滑孔321d的轴向上的相对位置。此结构简单,容易实现。
又示例的,图15为图14所示底座中顶杆的立体图。如图15所示,第一锁止结构3252包括第一滑块3252a,该第一滑块3252a设置于顶杆3251的侧壁上。图16为图14所示底座中滑孔的内表面的结构示意图。如图16所示,第一锁止结构3252还包括第一滑槽3252b,该第一滑槽3252b设置于滑孔321d的内壁上。第一滑槽3252b包括第一滑槽段3252b1和第二滑槽段3252b2。第一滑槽段3252b1沿滑孔321d的轴向延伸,第二滑槽段3252b2沿滑孔321d的周向延伸,第二滑槽段3252b2的一端连接于第一滑槽段3252b1的靠近连接部3243的一端。第一滑块3252a滑动连接于第一滑槽3252b内,在顶杆3251向第一位置滑动的过程中,第一滑块3252a在第一滑槽段3252b1内滑动。当顶杆3251滑动至第一位置时,第一滑块3252a滑动至第一滑槽段3252b1的靠近连接部3243的一端。在顶杆3251滑动至第一位置之后,第一滑块3252a能够由第一滑槽段3252b1滑入第二滑槽段3252b2内。
这样,在顶杆3251滑动至第一位置之后,可以旋转顶杆3251,并驱动第一滑块3252a由第一滑槽段3252b1滑入第二滑槽段3252b2内,由此固定了顶杆3251与滑孔321d之间在滑孔321d的轴向上的相对位置,将顶杆3251保持在第一位置。此结构简单,容易实现。
可以知道的是,在上述实施例中,第一滑块3252a和第一滑槽3252b的设置位置也可以为:第一滑块3252a设置于滑孔321d的内壁上,第一滑槽3252b设置于顶杆3251的侧壁上。这样,所达到的效果与上述实施例所达到的效果相同,在此不做赘述。
为了防止顶杆3251由滑孔321d掉出至绝缘壳体321外,在一些实施例中,如图15所示,顶杆3251的靠近连接部3243的一端位于绝缘壳体321内,且顶杆3251的靠近连接部3243的一端的侧壁上设有第一止挡凸起3253,第一止挡凸起3253用于阻止顶杆3251由滑孔321d掉出至绝缘壳体321外。
为了防止顶杆3251由滑孔321d落入绝缘壳体321的内部空间中,在一些实施例中,如图15所示,顶杆3251的远离连接部3243的一端位于绝缘壳体321外,且顶杆3251的远离连接部3243的一端的侧壁上设有第二止挡凸起3254,该第二止挡凸起 3254与绝缘壳体321间隔设置,当顶杆3251向靠近连接部3243的方向滑动至第一位置时,该第二止挡凸起3254与绝缘壳体321的外表面抵接。
这样,可以通过第二止挡凸起3254防止顶杆3251由滑孔321d落入绝缘壳体321的内部空间中,此结构简单,容易实现。
在一些实施例中,如图5所示,底座32还包括盖板326。盖板326的一端可旋转连接于侧臂部3212的远离底臂部3211的一端,盖板326的旋转轴线与绝缘壳体321相对于安装导轨的滑动方向(也即是图5中的方向X)平行。盖板326能够由第二位置向第二安装卡槽600的方向旋转至第三位置。图17为图5所示的底座中盖板位于第二位置时的结构示意图。如图17所示,当盖板326位于第二位置时,盖板326未遮挡第二安装卡槽600的开口,此时,断路器31可以卡入第二安装卡槽600,或者由第二安装卡槽600拔出。图18为图5所示底座中盖板位于第三位置时的结构示意图。如图18所示,当盖板326位于第三位置时,盖板326遮挡第二安装卡槽600的开口,此时,盖板326可以阻止第二安装卡槽600内的断路器31掉出,由此能够提高断路器31在底座32上的安装稳定性。
需要说明的是,上述实施例所述的第二安装卡槽600的开口是指第二安装卡槽600的背离底臂部3211的一端开口,断路器31由该开口卡入第二安装卡槽600或者拔出。
在一些实施例中,底座32还包括第二锁止结构,该第二锁止结构设置于盖板326与侧臂部3212之间,该第二锁止结构用于当盖板326旋转至第三位置时,固定盖板326与侧臂部3212之间的相对位置。这样,使盖板326能够阻止断路器31由第二安装卡槽600掉出。
第二锁止结构的结构形式有多种,比如螺钉、定位销等等,在此不做具体限定。
在一些实施例中,图19为图5所示底座中盖板与侧臂部之间的连接结构示意图。如图19所示,第二锁止结构327包括弹性卡臂3271和卡接缺口3272。弹性卡臂3271设置于盖板326上,且弹性卡臂3271沿绝缘壳体321相对于安装导轨的滑动方向(也即是图19所示的方向X)延伸。卡接缺口3272设置于侧臂部3212上,且卡接缺口3272的开口朝向第二安装卡槽600。当盖板326旋转至第三位置时,弹性卡臂3271卡接于卡接缺口3272内。此结构简单,容易实现,且当施加至盖板326的作用力能够克服弹性卡臂3271与卡接缺口3272之间的弹性卡接力时,则能够带动盖板326复位至第二位置,以打开第二安装卡槽600的开口,此时,可以更换或者安装断路器31。
为了进一步阻止断路器31由第二安装卡槽600掉出,在一些实施例中,图20为图5所示底座中盖板的爆炸图。如图20所示,底座32还包括第三锁止结构328。第三锁止结构328用于在盖板326旋转至第三位置时,固定弹性卡臂3271与卡接缺口3272之间的相对位置。这样,对盖板326进行二次锁止,使盖板326能够有效阻止断路器31由第二安装卡槽600掉出。
在上述实施例中,第三锁止结构328的结构形式有多种,在此不做具体限定。
在一些实施例中,如图20所示,第三锁止结构328包括第二滑槽3281和第二滑块3282。第二滑槽3281设置于盖板326上,第二滑槽3281沿与盖板326平行并与盖板326的旋转轴线l垂直的方向延伸。第二滑块3282滑动连接于第二滑槽3281内,且第二滑块3282能够沿第二滑槽3281由第四位置向靠近盖板326的旋转轴线l的方 向滑动至第五位置。

这样,可以将弹性卡臂3271锁止于卡接缺口3272内,以固定弹性卡臂3271与卡接缺口3272之间的相对位置。此结构简单,容易实现,且当施加至第二滑块3282的作用力能够克服止挡卡扣3283和止挡卡槽3284之间的弹性卡接力时,则能够带动第二滑块3282复位至第四位置,以解锁弹性卡臂3271,使弹性卡臂3271能够在外力作用下由卡接缺口3272滑出。
在一些实施例中,图21为图5所示底座中盖板的第二滑块位于第四位置时的结构示意图。如图21所示,第二滑槽3281包括第三滑槽段3281a和第四滑槽段3281b,第四滑槽段3281b位于第三滑槽段3281a的远离盖板326的旋转轴线的一侧。当第二滑块3282位于第四位置时,第二滑块3282位于第四滑槽段3281b内,未位于第三滑槽段3281a内。图22为图5所示底座中盖板的第二滑块位于第五位置时的结构示意图。如图22所示,当第二滑块3282位于第五位置时,第二滑块3282位于第三滑槽段3281a内,未位于第四滑槽段3281b内。第三滑槽段3281a的底面设有第一标识A,第四滑槽段3281b的底面设有第二标识B,第一标识A与第二标识B不同。
这样,当第二滑块3282位于第四位置时,第一标识A显露出来,则表示弹性卡臂3271处于解锁状态;当第二滑块3282位于第五位置时,第二标识B显露出来,则表示弹性卡臂3271处于锁止状态。由此,可以通过第一标识A和第二标识B来确定弹性卡臂3271处于解锁状态或者锁止状态。
在上述实施例中,第一标识A可以为“ON”字样,也可以为绿色的涂层区域,还可以包括绿色的涂层区域和设置于该绿色的涂层区域上的“ON”字样,当然,该第一标识A还可以是其他标识,在此不做具体限定。

在将上述温度检测模块329安装于底座32内时,如图5所示,温度检测模块329 设置于容纳腔400内。
其中,如图23所示,温度传感器3291设置于导电连接件322上,以检测导电连接件322的温度,由此防止导电连接件322因温度过高而产生变形甚至引起火灾。
可选地,如图11所示,导电连接件322的U型导电弹片上形成温度传感器容纳槽c,如图23所示,温度传感器3291安装于该温度传感器容纳槽c内,且该温度传感器容纳槽c的开口处设有遮挡片d,该遮挡片d与U型固定套323连接,且遮挡片d与U型固定套323一体成型。这样,可以防止温度传感器3291由该导电连接件322上掉出,此结构简单,容易实现。
另外,图24a为图5所示底座处于第四方位时的结构示意图。如图24a所示,绝缘壳体321上还设有第三连接口321e,该第三连接口321e与容纳腔400连通。接线插座3292靠近第三连接口321e设置,第三连接口321e允许接线插头000伸入容纳腔400内,以与接线插座3292配合插接。
如图5和图24a所示,底座32还包括第四锁止结构330。该第四锁止结构330设置于绝缘壳体321的外表面上,且该第四锁止结构330用于在接线插头000穿过第三连接口321e插接于接线插座3292上之后,固定接线插头000与接线插座3292之间的相对位置。
这样,可以通过第四锁止结构330固定接线插头000与接线插座3292之间的相对位置,防止接线插头000由接线插座3292上掉出。
第四锁止结构330的结构形式有多种,在此不做具体限定。

在上述实施例中,如图24a所示,第四锁止结构330还包括第一弹性卡扣3304和第一弹性卡槽3305。如图24c所示,第一弹性卡扣3304设置于滑轨3301上,如图24a所示,第一弹性卡槽3305设置于第三滑块3302上,当第三滑块3302滑动至第七位置时,第一弹性卡扣3304卡接于第一弹性卡槽3305内。这样,在第三滑块3302滑动至第七位置时,能够固定滑轨3301与第三滑块3302之间的相对位置,防止止挡件3303在止挡凸台001时产生位置移动。当施加至第三滑块3302的作用力能够克服第一弹性 卡扣3304和第一弹性卡槽3305之间的弹性卡接力时,则能够带动第三滑块3302复位至第六位置,以解锁接线插头000,使接线插头000能够由接线插座3292上拔出。
