具体实施方式
为了对本发明的技术特征、 目的和效果有更加清楚的理解, 现 对照附图说明本发明的具体实施方式。 尽管提供附图是为了呈现本 发明的一些实施方式, 但附图不必按具体实施方案的尺寸或形状绘 制, 某些特征可被放大、 移除、 局剖或以示意画法示出以便能更好 解释本发明的公开内容。 在说明书中出现的短语 "在附图中" 或类 似用语不必参考所有附图或示例。
在下文中被用于描述附图的某些方向性术语,例如 "上"、"下 "、 "左"、 "右"、 "向上"、 "向下" 和其它方向性术语, 将被理解为参 考附图所述的方向, 而不构成对本发明的具体限制。 另外, 对于装 置的方向性描述将按照本领域技术人员对于断路器领域的惯常方 向进行理解, 例如, 断路器插入方向可称为 "竖直方向"。
如图 1和 2总体所示, 提供了一种断路器组件 100, 其包括作 为组成部件的断路器底座 1和断路器 2。如本领域技术人员已知的, 该断路器 2配置成被插入该断路器底座 1中, 并紧固于其上, 以便 实现必要的断路器功能。 继续参考图 1和 2, 该断路器底座 1呈容 器状, 具有由壳体限定出的、 上端开口的内腔 11。 该断路器 2可以 是任何可是的插拔式断路器, 并且可以具有断路器可具有的已知的 合适部件, 如触头系统、 灭弧系统、 操作机构、 脱扣机构、 外壳等, 但为了本发明目的,仅示出了用作脱扣机构或者其部件的脱扣杆 21 以及用作操作机构或其部件的操作杆 22。人们将明白, 在脱扣机构 脱扣的时候, 操作人员将不能操作操作机构、 如操作杆 22合闸断 路器, 且处于合闸状态的断路器也会因此而跳脱, 从而此时断路器 处于断开状态。 断路器的这个功能是现有技术已知的, 在此不再赘 述。
结合参考图 3-5, 根据本发明的断路器组件 100的实施例还包 括安全保护装置 3, 该安全保护装置 3能够以非常简单的方式保证 断路器 2插入断路器底座 1的过程中保持断开状态, 从而提供安全 保护, 而且该安全保护装置尽量减少了介入断路器工作的可能性。 该安全保护装置 3可以包括配置成可抵接或脱离所述断路器 2的脱
扣机构、 在此为脱扣杆 21的推杆 31 ; 被保持在该断路器底座 1上 的控制仿形结构 32;以及可转动地安装至所述断路器 2的杠杆结构 33。 下面将分别描述该推杆 31、 控制仿形结构 32 和杠杆结构 33 以及与它们关联的安全保护装置 3的其他部件。
尤其如图 3所示, 该推杆 31呈细长杆状, 且可被插入断路器 2 中形成的孔中。 其中, 在推杆 31 内形成有空心部分, 用于容纳并 连接一复位弹簧 311,该复位弹簧 311用于朝远离脱扣杆 21方向偏 压所述推杆 31,从而在常态下推杆 31可以与脱扣杆 21隔开一安全 距离, 以免影响断路器的工作。 在所示的实施例中, 复位弹簧 311 例如呈拉簧形式一端连接推杆, 另一端连接断路器 2的固定部分, 但复位弹簧也可以是其他形式的偏压结构, 只要其适于朝远离脱扣 机构方向偏压推杆即可。在该推杆 31的底部形成有一腰孔 312, 通 过该腰孔 312,推杆 31可以与杠杆结构 33操作连接, 如下文详述。 在该推杆 31的顶部, 形成了一斜端面 313, 其构成了推杆 31的用 于可脱离地 4氐接脱扣杆 21的部分。
继续参考图 3-5, 为了支承安全保护装置 3的杠杆结构 33, 该 安全保护装置 3还具有杠杆结构支架 35。 该杠杆结构支架 35包括 用于多个固定螺孔 352、 所示为两个, 从而其例如可以固定安装至 断路器 2的底侧 (见图 1和 2)。 尽管在所示的实施例中通过螺纹安 装,但该支架 35可以通过其他方式固定至断路器 2、甚至可以与断 路器一体形成。 该支架 35还具有向外延伸的板状, 杠杆结构 33通 过一枢轴 333可枢转地安装至该支架 35的板状部分上。 在所示的 实施例中, 该枢轴 333是杠杆结构 33的一体部分, 且穿过支架 35 的板状部分中形成的孔中, 以便枢转安装,但也可以是杠杆结构 33 具有孔, 而枢轴形成在支架 35上。 如图所示, 该支架 35、 尤其是 其板状部分还形成有定位销轴 351。
如图所示, 该杠杆结构 33具有呈三角形的板状部分, 上述枢 轴 333位于三角形的一个顶点上, 且该杠杆结构在另两个顶点处分 别限定出第一杠杆端和第二杠杆端, 并且在第一和第二杠杆端处分 别合适地形成有第一销轴 331 (图 4)和第二销轴 332。该第一销轴 331 例如是绕自身回转轴线可回转地安装或者是简单地固定或一体成
形在三角板上, 并且被插入推杆 31的上述长形腰孔 312中, 从而 其可以在腰孔 312的纵向具有一定的自由度。 而第二销轴 332将可 以滑动抵接控制仿形结构 32,如下文详述。尽管在所示的实施例中, 上述杠杆结构 33具有三角形的基本形状, 但是也可以根据需要按 其他的形状设置, 只要能通过杠杆结构 33有效地将控制仿形结构 32与杠杆结构 33的第二杠杆端(第二销轴 332)的相互配合有效传递 至推杆 31使其合适地运动即可。 此外, 尽管在所示的实施例中推 杆 31和杠杆结构 33通过如此的销轴-孔形式配合,但也可釆用其它 的合适配合方式。
如图 3-5所示, 示出了呈仿形板形式的控制仿形结构 32, 该控 制仿形结构 32可包括多个功能轮廓段, 在所示的实施例中为三个, 即第一功能轮廓段 321、 第二功能轮廓段 322 和第三功能轮廓段 323 , 但可以想到, 根据需要设置更多或更少的功能轮廓段。 在所 示的实施例中, 所述功能轮廓段由仿形板的侧边缘限定, 且为了方 便描述, 在图 5中沿着轮廓边缘平行地画出功能轮廓段的示意线, 以该示意线表示轮廓段。 尤其如图 5所示, 所述第二轮廓段 321是 平直轮廓段, 所述第一和第三轮廓段 321、 323相对于第二轮廓段 332倾斜设置, 由此呈现第二轮廓段 332相比于第一和第三轮廓段 321、 323 "突出"。 下文将进一步结合其功能进行描述。
如图 4所示, 该控制仿形结构 32还具有钩部 324, 一弹性件 37、 例如拉簧一端连接该钩部 324, 另一端连接断路器底座 1, 从 而将控制仿形结构 32支承在断路器底座 1上, 优选地, 位于断路 器底座 1的内腔 11内。
如图所示, 该安全保护装置 3还可以包括用于将该控制仿形结 构 32支承在断路器底座 1上的支承板 34。 在所示的实施例中, 该 控制仿形结构 32与支承板 34—体形成, 例如由钣金件一体地弯折 出该成仿形板状的控制仿形结构 32。此外, 该安全保护装置 3还可 包括螺栓机构。 如图所示, 该螺栓机构可以包括多个紧固螺栓 36, 相应地, 该支承板 34 的相应部分, 具体而言是在两端形成有螺纹 孔 341, 该螺栓机构的功能将在下文说明。 参考图 1和 2, 该断路 器底座 1可以在两侧形成有朝内开口的凹陷 12, 该支承板 34的螺
纹孔 341 部分被插放凹陷 12 中, 且凹陷的高度 (厚度)大于支承板 34的厚度(高度),并且在凹陷 12的顶侧形成有供螺栓 36穿过的孔、 优选是光孔 (未示出)。 在如图所示, 该支承板 34上还可以形成有指 示机构 342、 在此呈镂空的箭头形式, 以指示操作人员按正确方向 插入断路器。
下面将描述根据本发明的断路器组件 100 的安装方法的实施 例。 参考图 1和 2所示, 可选地通过将支架 35固定至断路器 2, 从 而将安全保护装置 3的杠杆结构 33可转动地安装至该断路器 2,且 推杆 31安装成与杠杆结构 33的第一杠杆端连接, 并且插入断路器 2的孔内, 并被复位弹簧 311偏压成与脱扣杆间隔开。 或者, 可以 提供一个断路器装置, 其上如上所述地结合有该断路器 2、 杠杆结 构 33和推杆 31。
相应地, 通过弹性件 37将控制仿形结构 32以及支承板 34支 承在断路器底座 1上, 尤其支承板 34的螺纹孔 341部分被保持在 凹陷 12的下侧。
此后, 将断路器 2以及杠杆结构 33插入断路器底座 1 中, 尤 其是通过定位销轴 351与仿形板的远离功能轮廓段一侧对齐的方式 将杠杆结构 33插入断路器底座 1的内腔 11内。在插入的初始阶段, 由于复位弹簧 311的作用, 第一销轴 331被保持在下部位置, 从而 第二销轴 332相比于第二功能轮廓段 332更靠控制仿形结构 32的 内部, 从而第二销轴 332首先接触第一功能轮廓段 321 , 并在其上 滑动。 通过该第一功能轮廓段 331的倾斜设置, 其促成了促成所述 第二销轴 332滑上 "突出" 的第二功能轮廓段 322。 借此, 在进一 步插入断路器 2时, 第二销轴 332通过第二功能轮廓段 332 "朝外" 运动(图中朝右侧), 如此使得第一销轴 331倾向于朝上运动, 并由 此使推杆 31克服复位弹簧 331的作用朝上运动 (第一销轴 331和长 形腰孔 312之间还可有相对运动),由此在第二销轴 332在平直的第 二功能轮廓段 322上滑动时, 推杆 31保持在向上的位置(图 1), 并 抵接脱扣杆 21, 从而使得合闸的断路器 (如果)脱扣并保持开闸, 而 且此时操作人员也不能操作合闸。 在所示的实施例中, 在断路器 2 完全插入位置(图 1), 第二销轴 332来到第二功能轮廓段 322末端,
此时断路器 2抵接凹陷 12的下侧壁(图 1)。
之后, 可以通过接合螺栓结构, 即通过拧入螺栓 36, 使得螺栓 36与支承板 34的螺纹孔 341接合,并且使得支承板 34以及控制仿 形结构 32克服弹性件 37的偏压力向上运动并抵接凹陷 12的上侧 壁(图 2), 此时不仅实现了断路器 2和断路器底座 1的紧固, 更重 要的是通过该紧固动作还能够使得第二销轴 332滑入 "倾斜" 的第 三功能轮廓段 323 , 如此可允许第二销轴 332 "向内" 运动, 而第 一销轴 331向下运动, 从而推杆 31朝远离脱扣杆 21的方向运动并 与之间隔一安全的小间距。 此时, 操作人员可以在断路器完全插入 并且良好紧固的情况下自由合闸断路器, 而安全保护装置 3此时不 会干涉断路器的工作。 可见, 该螺栓机构一方面起到用于在断路器 2插入后移动所述控制仿形结构 32使其接近断路器 2, 并进而使得 杠杆结构 33 以及推杆 31移动离开脱扣杆 21的移位功能; 另一方 面还起到将所述控制仿形结构 32紧固在断路器 2上以及将断路器 2 紧固于断路器底座上的紧固机构。 尽管在所示的实施例中螺栓机构 同时起到上述两个功能, 但人们将能想到独立提供两个机构、 即移 位机构和紧固机构来实现上述功能。 尽管在所示的实施例中, 通过 设置凹陷 12的上下侧壁来分别提供支承板(并进而控制仿形结构) 的支承和紧固, 但也可以想到设置向上敞开的台阶、 如双级台阶, 断路器完全插入时位于上台阶上, 而此时支承板位于下台阶, 移位 机构使得支承板的移位将会由断路器自身限制。
尽管在所示的实施例中, 断路器 2插入之后第二销轴 332留在 第二功能轮廓段 322, 但可以如此设计使得第二销轴 332在插入的 末期进入第三功能轮廓段 323, 然后通过螺栓机构的移位作用, 使 得第二销轴 332在第三功能轮廓段 323中进一步滑动, 或者滑入进 一步的、例如第四功能轮廓段 (未示出)中以确保推杆 31在紧固安装 后安全地与脱扣杆 21间隔开。
尽管在所示的实施例中, 安全保护装置作为断路器组件 100的 独立于断路器底座 1和 /或断路器 2的装置进行描述,但人们可以明 白该安全保护装置的部分或全部功能可以由断路器底座和 /或断路 器提供,而该具有本发明构思的断路器底座和 /或断路器仍落入本发
明的范围内。 例如, 一个断路器集成有该安全保护装置的杠杆结构 以及可能有的杠杆结构支架, 且适用于例如根据本发明的安全保护 装置的控制仿形结构或安装有或者集成有控制仿形结构的断路器 底座, 则该断路器落入本发明保护范围内, 同样, 该集成控制仿形 结构的断路器底座落入本发明的范围内。 以上仅是结合有本发明思 想的装置示例, 而不是穷尽, 本发明的范围由所附权利要求书及其 等同限定。
以上所述仅为本发明示意性的具体实施方式, 并非用以限定本 发明的范围。 任何本领域的技术人员, 在不脱离本发明的构思和原 则的前提下所作的等同变化、 修改与结合, 均应属于本发明保护的 范围。
