Description

一种断路器 技术领域
本发明涉及配电领域的断路器， 更具体的说， 涉及一种可实现多种导线混 接的断路器。 背景技术
现有断路器， 特别是小型断路器的接线功能主要依靠接线端子与回路导线 的可靠连接来实现。 断路器早期主要用于线路末端保护， 对于该回路， 断路器 仅需实现一种导线接线功能便可得到应用。 随着断路器应用范围的扩大， 因电 力系统或者电路设计的分配需要， 常常将下一级并列系统或并列线路中的断路 器的每一相进行分线接线。 举例来说， 当线路中需要从总开关出线端分成多个 并联支路， 通常釆用将这些并联支路上的断路器的同相接线端进行并联的接线 方式。 釆用这种接线方式之后， 断路器可接入的导线种类， 从最初的一种增加 到两种。 接线种类的增加， 导致了现有断路器可连接的导线出现了各种各样的 排列组合。 目前市场上断路器常用的导线分为： 多股线、 单股线、 汇流排（母 排）、 为实现快速接线使用带环形接头的导线。 因此一种可实现任意两种常用导 线组合接线功能的断路器将能更快的适应市场的需求。
在现有技术领域， 实现断路器的接线功能釆用如下技术方案。
第一种技术方案， 见图 1 , 断路器壳体内安装有接线板和接线端子， 接线 端子包括能与接线板发生相对移动的接线座， 与接线座釆用螺紋配合的螺钉。 将导线接入接线座与接线板之间， 并用螺钉进行紧固， 实现断路器的接线功能。
第二种技术方案， 见图 2 , 是目前断路器最常见的接线方式， 以前一技术方 案为基础， 在接线座运动的方向上， 增加第二接线板， 该接线板与原有接线板 等电位， 与接线座釆用螺紋配合的螺钉， 穿过第二接线板， 通过螺钉与第二接 线板实现汇流排（母排）接线功能。
仔细对比现有两种技术方案， 不难看出， 如果以第二技术方案为基础， 同 样可以设计出供第一种技术方案所使用的汇流排（母排） 功能， 第二种技术方 案相比第一种技术方案， 是通过两块接线板将汇流排（母排）接线功能与常规 接线功能分开， 相互独立。 这使得第二技术方案可实现汇流排（母排）接线功 能外， 还能实现第一技术方案的所有接线功能， 但也不可避免的使接线端子和 接线板的结构复杂。
另外， 前述两种技术方案中接线板与接线座只形成了一个接线空间， 在可 接导线的组合上， 不能实现不同线径的单股导线混接。
与此同时， 两种技术方案均不能实现在快速接线中， 使用带环形接头的导 线， 仅能使用汇流排（母排）接线功能。
进一步， 如前所述两种技术方案， 当断路器完成导线接线后， 不难想象， 当对多极断路器连接导线后， 导线棵露端处于断路器壳体之外， 相邻两个导线 的电气间隙和爬电距离很小， 如导线发生短接， 必定会带来安全隐患， 当使用 汇流排（母排）接线时， 虽然不存在相邻极之间的短接， 但电气间隙和爬电距 离偏小， 在长期使用过程中， 因绝缘材料性能的降低， 而同样会带来后期使用 安全隐患。 发明内容

本发明公开了一种断路器， 包括壳体， 设置于壳体内的接线板 1 和接线端 子 2 , 所述的接线端子 2包括螺钉 6、 压板 7、 设有进线孔和接线空间的接线座 8 , 所述螺钉 6穿过接线座 8顶端面 29的螺紋孔与嵌入接线座 8内可升降的压 板 7接触； 所述接线板 1横穿接线座 8将接线座 8的接线空间分隔成两个独立 的接线空间 23、 24 ; 接线板 1、 压板 7和接线座 8侧壁之间形成第一接线空间 23 , 接线板 1、 接线座 8底端面 14和接线座 8侧壁之间形成第二接线空间 24 ; 所述壳体在接线端子 2的螺钉 6的上方位置设有第一接线孔 4 ;所述压板 7和接 线座 8通过螺钉 6的作用与接线板 1发生相对位移压缩所述两个独立接线空间 实现导线的连接。 进一步， 本发明的断路器还包括可与汇流排导线连接的接线 排附件 22 ; 所述接线排附件 22包括与所述两个独立接线空间 23、 24的任—— 个连接的连接排 18 , 以及用于固定连接排 18的设有进线孔的绝缘隔板 16 ; 所 述绝缘隔板 16沿导线进线方向固定在壳体上。 进一步， 所述连接排 18上设有 可与带环形接头的导线连接的接线螺钉 17 ,所述壳体在接线排附件 22的接线螺 钉 17的上方位置设有第二接线孔 3。
本发明以接线板为分界， 将接线座的接线空间分隔成两个相互独立的接线 空间， 等效分出了两个接线端子， 两个接线端子可以完成各自的接线功能， 互 不干扰。 本发明结构简单， 在保留现有第一种技术方案所有功能的同时， 还实 现了不同线径的单股导线混接的接线功能。 进一步的， 本发明还可加设与接线 端子连接的接线排附件， 在不增加接线板的情况下实现现有第二种技术方案与 汇流排（母排）类型接头的导线混接， 拓展了断路器可混接导线的类型。 进一 步的， 本发明在连接排附件上设有接线螺钉， 实现与带环形接头的导线混接， 进一步拓展了断路器可混接导线的类型。 进一步的， 在壳体内设有接线通道， 通过接线通道将导线与接线端子连接时的棵露端置于壳体内， 并且提高了爬电 距离和电器间隙有效隔离多极断路器连接导线后相邻导线之间的安全隐患， 实 现电气安全防护。
下面结合附图和较佳的实施例对本发明作进一步说明。
如图 3 ~ 6所示， 本实施例的断路器包括封闭的壳体， 壳体包括绝缘的第一 壳体 5A和第二壳体 5B ,第一壳体 5A和第二壳体 5B内设有容纳断路器各部件的 空间及各种拼接紧固部件， 断路器的操作机构、 触头装置、 脱扣器、 灭弧室等 部件分别固定在两部分壳体内部， 然后两部分壳体拼接固定， 将内部部件完全 固定并实现可靠密封， 形成完整的断路器。
在断路器壳体的内部，其接线端和出线端位置均设有接线板 1和接线端子 2。 接线端子 2包括与接线板 1相互配合，并能与接线板 1发生相对移动的接线座 8 , 与接线座 8釆用螺紋配合的螺钉 6 , 以及与螺钉 6相互配合， 并随螺钉 6的推动 而产生与接线板 1相对移动的压板 7。接线座 8设有进线孔和接线空间， 成空心 矩形结构， 其空心部分为接线空间， 接线座 8顶端面 29设有螺紋孔， 螺紋孔内 设有螺钉 6 ,螺钉 6的螺紋端通过螺紋孔与嵌入接线座 8内可升降的压板 7接触。 接线座 8的内部还横穿有接线板 1 ,接线板 1固定在壳体上， 将接线座 8的接线 空间分隔成两个相互独立的接线空间，接线板 1、压板 7和接线座 8侧壁之间形 成第一接线空间 23 ,接线板 1跟接线座 8底端面 14和接线座 8侧壁之间形成第 二接线空间 24。 壳体在接线端子 2的螺钉 6的上方位置设有第一接线孔 4 , 安 装导线的时候， 螺丝刀可以通过第一接线孔 4 进入壳体内拧紧螺钉。 在第一壳 体 5A和第二壳体 5B内壁导线与接线端子 2连接的进线方向上设有凸起的引导 导线接入两个独立的接线空间的导向板 12 ,导线板 12的端面跟接线板 1的端面 平齐，通过导向板 12可以方便弓 I导导线分别接入相应的两个独立的接线空间内。
在进行导线连接时， 拧动螺钉 6进行紧固， 首先压板 7会随着螺钉 6的推 动不断的向接线板 1运动， 固定位于压板 7和接线板 1之间的导线， 实现第一 接线空间 23的接线功能。 继续紧固螺钉 6 , 当压板端面 9与接线板上端面 1 1接 触后， 螺钉 6不再向下运动， 接线座 8在螺紋配合下沿着螺钉 6往上运动， 接 线座底端面 14向接线板下端面 1 3运动压紧位于接线座 8和接线板 1之间的导 线， 从而实现第二接线空间 24的接线功能， 最终完成任意两种常用导线的接线 功能， 而两个接线空间都可以看成独立的接线端子。 本实施例结构简单， 以接线板为分界将接线座的接线空间分隔成两个相互 独立的接线空间， 两个接线空间可以完成各自的接线功能。 可以实现多股线、 单股线等普通导线的连接， 同时也实现了不同线径的单股导线混接的接线功能。 本技术方案以一个接线板为分界， 将接线座的接线空间分隔成两个相互独立的 接线空间， 对于本领域技术人员来说， 显而易见可以将本技术方案扩展为多个 接线板， 这些接线板都处于同一电位， 以接线板为分界， 将接线座的空间分隔 成多个独立空间， 实现多个常用导线的混接。
通过第一接线孔 4、接线端子 1和接线板 1形成的两个独立接线空间的导线 连接方案适合常用的接线板和接线端子， 可以安装的导线接头类型有一定的限 制， 因此， 为了拓展了断路器的适用范围， 以适应更多类型接头的导线， 断路 器还可以根据接线情况的需要加设可与汇流排（母排）导线连接的接线排附件 22。 如图 7-9所示， 所述接线排附件 22 包括与所述两个独立接线空间 23、 24 的任——个连接的连接排 18 ,以及用于固定连接排 18的设有进线孔的绝缘隔板 16; 所述绝缘隔板 16沿导线进线方向固定在壳体上。 当安装接线排附件 22时， 连接排 18接入接线端子 2的其中一个独立接线空间内，并保持一定的安装力矩， 绝缘隔板 16沿导线进线方向安装配合在壳体上后， 完成接线排附件 22的安装， 实现接线功能扩展并保证电气安全防护。 通过接线排附件 22使得本实施例实现 了与汇流排 (母排） 的导线混接。
进一步的， 连接排 18上设有可与带环形接头的导线连接的接线螺钉 17 , 壳 体在接线排附件 22的接线螺钉 17的上方位置设有第二接线孔 3 ,螺丝刀可以通 过第二接线孔 3进入壳体内拧紧接线螺钉 17。 所述第二接线孔 3与第一接线孔 4并排设置沿第一壳体 5A和第二壳体 5B的配合平面延伸。 通过接线排附件 22 使得本实施例实现了与汇流排（母排） 的导线混接。 通过增加接线螺钉的设置 使得本实施例实现了与带环形接头的导线混接。
如图 7所示， 本实施例中连接排 18包括嵌入所述两个独立接线空间 23、 24 的任——个的电连接部 27 , 以及跟电连接部 27 固定连接的安装部 28 , 电连接 部 27成四方形柱体， 安装部 28的宽度大于电连接部 27 , 这样安装部 28超出电 连接部 27的部分就形成凸缘， 形成两个连接排端面 21 , 接线螺钉 17设于安装 在第一壳体 5A和第二壳体 5B上设有与连接排 18的安装部 28两侧的连接 排端面 21相对应的定位面 1 0 ,所述电连接部 27嵌入所述两个独立接线空间 2 3、 24的任——个后， 连接排端面 21嵌入到定位面 1 0中。 定位面 1 0在保证连接排 18接入接线空间实现可靠导向的同时，抵消连接排 18与带环形接头的导线连接 时， 由连接排 18上的接线螺钉 17紧固产生的扭距， 阻止连接排 18沿扭距平面 摆动， 保证接线排附件 22接线功能可靠。
所述绝缘隔板 16上设有止动销 15 , 所述止动销 15与壳体上相应位置设置 的止位档 19相互啮合实现绝缘隔板 16 自锁固定。 当绝缘隔板 16沿安装方向配 合在壳体上后， 止动销 15与止位档 19相互啮合， 阻止绝缘隔板 16沿安装方向 在壳体上滑动或脱落， 实现绝缘隔板 1 6 自锁， 保证接线排附件 22安全防护可 靠， 同时方便拆装。
显而易见， 本实施方式釆用了并排设置的两对接线孔（第一接线孔 4、 第二 接线孔 3 ), 以及可以加设接线排附件 22的设计， 在壳体内导线与接线端子 2连 接的进线方向上形成距离不小于第一接线孔 4与第二接线孔 3距离的容纳导线 棵露端的接线通道 20。 由于接线通道 20的存在，接线端子 2的接线的开口相当 于嵌入在壳体内部， 导线接入接线端子 2 内部， 即便有部分金属棵露在接线端 子 2外部， 接线通道 20也可以将棵露部分隔离开来， 当多极断路器连接完成导 线连接后， 相邻导线之间被这些接线通道相互分隔， 而提高了爬电距离和电气 间隙， 杜绝了导线之间短接的安全隐患， 实现电气安全防护。 避免了导线棵露 端处于断路器壳体之外， 多极断路器连接导线后相邻两个导线的电气间隙和爬 电距离很小而带来的安全隐患。
当然， 不难想象， 本实施方式所述的通过接线通道 20实现的电气安全防护 功能， 也可以在没有两对接线孔设计和加设接线排附件设计的普通断路器中实 现， 只需要在壳体内接线端子的导线进线开口处预留一定的保护通道即可， 当 然这会增加断路器体积。
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。
