本发明涉及一种模数化终端电器的手柄锁定装置， 特别是模数化终端电流断路器 （以 下简称断路器） 的操作手柄锁定装置， 当断路器的手柄或电气回路在断开 （OFF) 状态位置 时， 对断路器的手柄进行锁定， 防止人为对断路器手柄进行合间操作。 背景技术
在配电系统中， 以低压断路器为主的模数化终端电器使用量第一面广， 它不仅具有对 主电路或设备的通 （ON) /断 （OFF ) 控制功能， 而且还具有对主电路或设备进行过载、 短 路、 过压等保护功能。 随着用电安全管理标准的不断提高， OFF状态锁定功能成为用电管理 和安全管理中最常用而又十分重要的功能之一， 所述的 OFF 状态锁定是指将断路器的动触 头与静触头锁定在分断且不能闭合的断开 （OFF) 状态的位置。 OFF状态锁定主要用于配电 系统中的断路器， 当配电系统中某一断路器的保护支路发生故障使断路器跳闸或设备发生 故障不能正常工作时， 需要对故障原因进行排查， 只有当所有故障排除后， 该断路器才能 合闸投入使用， 在人为进行故障排查过程中， 操作电工往往会远离保护用断路器到保护支 路的各位置或设备处进行排查， 此时， 是不允许对该断路器进行合间操作的， 以避免操作 电工发生触电事故， 为保障操作电工的人生安全， 只有对保护回路的断路器的手柄锁定于 断开 （OFF) 位置， 禁止断路器合闸， 从根本上切断电源的传输路径， 才能确保专业人员在 检修过程中的人生安全。 此外， 通过 OFF 状态锁定功能进行限电管理也比较常用， 特别是 在不连续用电的公共场合， 经常需要在某时间段内禁止用电对象擅自操作断路器合闸。 所 述的 ON状态锁定是指将断路器锁定在闭合 （ON) 的状态， 使其不能手动分闸， 但不妨碍故 障跳闸。 ON状态锁定主要用于一些不需要跳闸保护功能或跳闸后手柄仍可处在 ON位置的终 端电器， 其用途是保护负载侧运行中不易断电的用户不会因随意断电而影响工作或损坏设 备。
已有的 OFF 状态锁定装置的原理主要有两种： 一种是内置式锁定装置， 它的锁定装置 设置在断路器内， 通过断路器上的锁定钮或远程控制器操作内置的锁定装置的锁定 /解锁， 其缺点是结构复杂、 占用宝贵的断路器内部的空间、 锁定的状态显示不直观、 锁定的安全 可靠性差等， 所以不常用； 另一种是外置式的锁定装置， 它通过限制断路器手柄的动作来 锁定断路器不能合闸而可靠保持在 OFF 状态， 其优点是结构简单、 锁定的状态显示直观、 锁定的安全可靠性好， 因而被广泛采用。 按结构分类， 已有的模数化终端电器的 OFF 状态 锁定装置的结构类型大致为两类： 第一类是可拆卸式 OFF状态锁定装置， 主要适用推行 IEC 标准或不对锁定装置结构进行明确规定的国家和地区， 其结构小巧， 用户通过拆卸功能可 方便选择是否在断路器上安装锁定装置， 但缺点是不适用于推行 UL标准即对锁定装置的结 构有明确规定的国家和地区； 第二类是不可拆卸式 OFF状态锁定装置， 主要适用于推行 UL 标准即对锁定装置的结构有明确规定的国家和地区， 当然也可以在推行 IEC 标准或不对锁 定装置结构进行明确规定的国家和地区使用。 它与断路器拼装在一起， 用户不能随意拆卸， 现有的不可拆卸式手柄锁定装置普遍存在的问题是不符合模数化标准的要求， 即： 锁定装 置的高度高于终端电器手柄运动过程中整个电器的最高高度， 从而不能适配于模数化标准 的终端配电箱， 在检修或维护工作结束即取消锁定功能后， 在手柄旁的锁定装置高度都高 于断路器的最高外形尺寸， 当断路器装设在箱体中时， 则因锁定装置的高度高于终端电器 的最高外形尺寸且不可调而致模数化终端配电箱的透明罩壳不能盖上， 不得不增加箱体的 高度即透明罩壳的高度尺寸， 影响装置在配电箱中使用的兼容性， 同时影响外观一致性。 例如美国专利 US7355132B1或 US2008/0277250A1公开的外置式的手柄锁定装置， 它们都设 有用于操作终端电器的 0N/0FF状态的手柄， 都包括一个永久高于断路器的最高外形尺寸的 构件， 当锁定装置和模数化终端电器拼装后， 其操作面板的结构占有空间较大， 或装置的 高度不可调， 这不仅影响了手柄锁定装置与模数化配电箱的兼容性、 适配性， 而且还给断 路器在解锁状态下的合闸和分闸正常操作带来极大的不便， 即手指不能方便地操作断路器 的手柄， 存在一些不符合 UL标准要求的问题。 发明内容
本发明的目的在于克服现有技术的上述缺陷， 提供一种模数化终端电器的手柄锁定装 置， 通过可运动的滑块，不仅可使锁定装置在 "锁定"和 "解除锁定"两状态下的高度不一 致， 且解除锁定状态时的高度要低于锁定状态时的高度， 在解锁状态下任何构件都不会影 响断路器的正常操作。
本发明的另一个目的是提供一种模数化终端电器的手柄锁定装置， 使得锁定装置的高 度绝对不高于模数化终端电器的最高外形尺寸， 它不仅具有外置不可拆卸式锁定装置结构 简单合理、 锁定的状态显示直观、 锁定的安全可靠性好等特点， 而且还具有与模数化配电 箱的兼容性好、 锁定和解锁操作便捷而又充满人性化的优点。

下面结合附图 1至 21所示的以模数化低压断路器为例的第一实施例和第二实施例， 详 细说明本发明的模数化终端电器的手柄锁定装置的结构、 动作原理及其优越性。 图 1-7 所 示的第一实施例的锁定装置既可实现 OFF状态锁定， 也可实现 ON状态锁定，而图 8-13所示 的第二实施例的锁定装置只能实现 OFF 状态锁定。 在详细说明第一、 第二实施例之前， 首 先说明第一与第二实施例共同的结构， 即组成这些结构的零部件都是通用的。 本发明的断 路器 10的手柄锁定装置都主要由壳座 1、 锁定机构 2和挂锁 3这三个部分组成 （图 1 ) ， 本发明将锁定功能件采用滑块模式实现， 使锁定和解除锁定两种状态下锁定功能件能够改 变位移， 以自动调整锁定装置在前述两种状态下的不同高度。 图 21为断路器正常工作时， 锁定机构 2 的滑动件滑入的实例， 图 1 为断路器手柄被锁定时， 滑动件 （未示出） 滑出状 态的实例。 参见图 2， 锁定装置的壳座 1通过连接机构可固定安装在断路器 10外壳左边的 外侧面 103a或右边的外侧面 103b上， 而现有锁定装置只能拼装在断路器 10外壳的某一个 外侧面上。 在断路器 10的外壳的两侧设置有至少一对预留孔 101a、 101b , 预留孔 101a或 101b均为贯穿并透过断路器 10的外壳的内、 外侧面上的通孔； 相对应地， 锁定装置的壳座 1上形成至少一对弹性倒钩 l la、 l ib , 它们通过弹性臂 l l la， 111b形成在壳座 1上， 即弹 性倒钩 11a或弹性倒钩 l ib均包括一个弹性臂 l l la， 111b。所述的连接机构由该预留孔 101a、 101b和弹性倒钩 l la、 l ib构成， 通过弹性倒钩（l la、 1 lb)与预留孔（101a、 101b)它们的卡 接配合， 将壳座 1固定安装在断路器 10的侧面 103a， 或 103b上。 这里卡接配合是指： 当 弹性倒钩 l la、 弹性倒钩 l ib分别插入预留孔 101a、 预留孔 101b时， 插入操作的操作力克 服预留孔 101a、 101b对于弹性倒钩 l la、 l ib的反作用力， 使弹性臂 l l la、 111b弹性变形； 当弹性倒钩 l la、 弹性倒钩 l ib分别穿过预留孔 101a, 预留孔 101b后， 由于弹性倒钩 l la、 l ib失去了预留孔 101a、 101b的弹性反作用力， 使弹性臂 l l la、 111b 带动弹性倒钩 l la、 l ib复位， 在此复位状态下， 弹性倒钩 l la、 l ib钩住断路器 10外壳的内侧面， 从而使弹性 倒钩 l la、l lb固定在预留孔 101a、101b内，并将壳座 1固定安装在断路器 10的外侧面 103a 或 103b上。 当然， 也可实现将壳座 1固定安装在断路器 10的外侧面 103a或 103b上的替 代方案。
下面结合附图说明锁定装置的锁定机构 2及其工作原理。 如图 5、 7所示， 锁定机构 2 包括一个其上设有门洞 211的滑动件 21， 门洞 211内设有可向断路器 10方向打开的一扇横 枢门 22和一扇竖枢门 23， 横枢门 22通过横枢（图中未示出） 与滑动件 21枢转连接， 该横 枢的轴线 K1垂直于断路器 10的高度方向 Y， 竖枢门 23通过竖枢 （图中未示出） 与滑动件 21枢转连接， 该竖枢的轴线 Κ2平行于断路器 10的高度方向 Υ。 锁定机构 2通过移动副机 构与壳座 1连接安装， 使锁定机构 2只能沿断路器 10的高度方向 Υ作升 /降滑动， 并且通 过限位机构， 锁定机构 2 被限定在上升后的工作位置与下降后的隐藏位置之间滑动。 即该 移动副机构限定了锁定机构 2在壳座 1上只具有一个上升或下降的直线滑动的自由度， 而 限位机构则限定了锁定机构 2在壳座 1 上的上升或下降的直线滑动的范围。 当锁定机构 2 上升到其上限位置 （如图 1、 3、 4、 7、 8、 10、 11、 18所示位置） 时， 可以执行锁定操作， 所以将该位置定义为工作位置； 当锁定机构 2下降到下限位置 （如图 2、 21所示位置） 时， 锁定机构 2处于非工作状态并隐藏起来， 使包括锁定机构 2在内的手柄锁定装置的任何部 位均不超出断路器 10的在高度方向 Υ和宽度方向 X上的外形尺寸， 所以将该位置定义为隐 藏位置。 正是锁定机构 2在解锁状态下可下降到隐藏位置的功能， 使断路器 10的操作用的 面板 105不会被锁定装置的任何结构件额外占用， 即锁定装置和断路器 10拼装后适用于任 何适合安装模数化终端电器的配电箱。 由于断路器 10的在高度方向 Υ和宽度方向 X上的外 形尺寸是统一的、 标准化的， 所以断路器 10的在高度方向 Υ和宽度方向 X上的外形尺寸是 确定的， 即本发明的手柄锁定装置在解锁后其高度方向 Υ和宽度方向 X上的外形尺寸等于 或小于模数化标准统一规定的尺寸。 由于手柄锁定装置从侧面拼装、锁定机构 2能升降（即 高度可调） 并在解锁后可隐藏， 使得本发明的手柄锁定装置在安装到断路器 10上后， 保证 在解锁状态下手柄锁定装置的任何部位与断路器 10的面板 105不发生关联， 不会干扰断路 器 10的正常操作功能， 也不会影响断路器 10的 ON/ OFF状态的清晰显示。 而且采用上述 连接机构和锁定机构， 使得本发明的手柄锁定装置具有可靠、 有效的机械强度和机械性能， 能确保在锁定状态下模数化终端电器不能被操作。 具体地说， 在锁定机构 2 处于上升后的 工作位置状态下： 锁定机构 2允许先打开横枢门 22， 即如图 7、 8所示的横枢门 22绕横枢 的轴线 K1 向断路器 10的方向 （转动方向 M的反方向） 翻转， 使横枢门 22与断路器 10的 手柄 102配合 （即横枢门 22的第一侧沿 221a与手柄 102接触配合） 而阻挡手柄 102不能 往回转动， 然后再打开竖枢门 23， 即如图 7、 8所示的竖枢门 23绕竖枢的轴线 K2向断路器 10的方向 （转动方向 N的反方向）翻转， 使竖枢门 23与横枢门 22配合 （即竖枢门 23的下 沿与横枢门 22的上面 222接触配合） 而阻挡横枢门 22不能回转， 最后挂锁 3从门洞 211 上锁、 并使挂锁 3与竖枢门 23配合 （即挂锁 3的锁环 31与竖枢门 23的里面接触配合） 而 阻挡竖枢门 23不能回转 （如图 1、 3、 7、 8、 10 ) ， 从而将手柄 102锁定而不能摆动。 附图 所示的实施例的断路器的手柄为摆动式手柄， 从上述的锁定机构 2 的结构可见， 由于横枢 门 22与断路器 10的手柄 102配合不受手柄 102运动形式的限制， 所以横枢门 22的第一侧 沿 221a完全可以与直动手柄接触配合并使直动手柄不能往回移动， 因而本发明模数化终端 电器的手柄锁定装置不仅适用于摆动式手柄， 而且适用于直动式手柄。 在锁定机构 2 处于 上升后的图 1、 7、 8所示的锁定工作状态下， 锁定机构 2也允许先卸下挂锁 3， 然后合拢竖 枢门 23， 即如图 7、 8所示的竖枢门 23绕竖枢的轴线 K2向门洞 211的方向 （转动方向 N的 方向）往回转动， 再合拢横枢门 22， 即如图 7、 8所示的横枢门 22绕横枢的轴线 K1向门洞 211 的方向 （转动方向 M的方向） 往回转动， 最后将横枢门 22和竖枢门 23均收回到门洞 211内 （如图 4、 11所示） 。 在图 4、 11所示的锁定机构 2处于上升后的位置但非锁定的状 态下， 允许作下降操作， 用人手将锁定机构 2往下按， 直到图 21所示的隐藏位置。 在锁定 机构 2处于图 21所示的下降后的隐藏位置状态下，横枢门 22和竖枢门 23均收回在门洞 211 内， 以不妨碍锁定机构 2的升 /降滑动， 且锁定机构 2的高度低于断路器 10的高度。 在锁 定机构 2处于下降后的隐藏位置状态下， 允许作上升操作， 用人手将锁定机构 2 向上拉， 直到图 4、 11所示的上升位置。 在锁定机构 2处于图 4、 1 1所示的上升位置的状态下， 允 许作打开横枢门 22和竖枢门 23的操作， 直到图 3、 7、 8、 10所示状态。 在图 3、 7、 8、 10 所示状态下， 允许作上锁操作， 直到图 1所示状态。
锁定机构 2的移动副机构包括形成在滑动件 21上的一对滑块 212a、 212b (图 3_5 ) 和 形成在壳座 1上的一对滑槽 12a、 12b (图 15 ) ， 滑块 212a、 212b和滑槽 12a、 12b按移动 副形式形成可动连接， 从而将锁定机构 2连接安装在壳座 1上。 所谓移动副形式是指将滑 块 212a、 滑块 212b分别插入滑槽 12a、 滑槽 12b， 通过滑块 212a、 212b与滑槽 12a、 12b 的滑动配合， 实现滑块 212a、 212b与滑槽 12a、 12b之间的可动连接， 即形成锁定机构 2 的滑动件 21与壳座 1可动连接， 从而将锁定机构 2连接安装在壳座 1上， 其特点是滑动件 21与壳座 1之间只有一个直线滑动的自由度。附图所示的移动副机构的结构是优选的方案， 可替代的移动副机构的结构是： 所述的移动副机构包括形成在壳座 1 上的一对滑块 （图中 未示出） 和形成在滑动件 21上的一对滑槽 （图中未示出） ， 滑块和滑槽按移动副形式形成 可动连接， 从而将锁定机构 2连接安装在壳座 1上。
参见图 15、 17、 19， 锁定机构 2的限位机构包括形成在壳座 1上的槽孔 13和与滑动件 21固定连接的滑动销 213， 滑动销 213安装在槽孔 13内并与槽孔 13滑动配合 （如图 19所 示）， 槽孔 13包括一个上限位面 131和一个下限位面 132， 通过上限位面 131与滑动销 213 的接触阻挡， 将滑动件 21限定在上升后的工作位置， 通过下限位面 132与滑动销 213的接 触阻挡，将滑动件 21限定在下降后的隐藏位置。可替代附图所示的限位机构的结构方案是: 限位机构包括形成在滑动件 21上的槽孔 （图中未示出） 和与壳座 1固定连接的滑动销 （图 中未示出） ， 滑动销安装在槽孔内并与槽孔滑动配合， 槽孔包括一个上限位面和一个下限 位面。 滑动销 213与滑动件 21 (或滑动销与壳座 1 ) 之间的固定连接的结构可采用螺纹连 接、 销连接、 粘接或者一体成形。 在槽孔形成在滑动件 21上的情况下， 所述的槽孔的上限 位面仍然是指上面的 （即靠近门洞 211 的） 那个限位面， 而槽孔的下限位面仍然是指下面 的 （即远离门洞 211的） 那个限位面。
本发明的模数化终端电器的手柄锁定装置还包括用于限定滑动件 21不能在特定的位置 上自由滑动的定位机构， 具体是指需要将滑动件 21 限制在隐藏位置和 /或工作位置上而不 能自由滑动， 包括： 仅限制在隐藏位置不能自由滑动； 或者仅限制在上升位置不能自由滑 动； 或者不仅限制在隐藏位置不能自由滑动， 并且还限制在上升位置不能自由滑动。 从手 柄锁定装置的工作原理讲， 如果不设定位机构， 手柄锁定装置也能正常工作， 但是， 采用 定位机构可使手柄锁定装置的性能更加完善， 例如限制在隐藏位置不能自由滑动的性能， 可以使手柄锁定装置在各种安装位置上都不会自由滑动； 限制在上升位置不能自由滑动的 性能， 可以使手柄锁定装置的锁定操作更加便捷。 所述定位机构的功能仅需限定滑动件 21 不能在特定的位置上自由滑动， 它不能限定滑动件 21在升 /降操作情况下的滑动， 或者说， 人手对锁定机构 2的升 /降操作可以自动解除定位机构对滑动件 21的滑动限制。 如附图 5、 12、 16、 17所示的实施方式， 定位机构包括一对形成在滑动件 21上的定位凹口 214a、 214b 和一对形成在壳座 1上的弹性凸起 14a、 14b , 在滑动件 21推入过程中， 先和凸点 19a、 19b 作用， 当继续推滑块的过程中， 弹性凸起 14a、 14b会滑入圆弧定位凹口 214a、 214b中。 当滑动件 21处在隐藏位置时， 两个弹性凸起 14a、 14b分别进入两个定位凹口 214a、 214b , 并与这两个定位凹口 214a、 214b弹性接触， 致使滑动件 21在弹性作用力下被限制在隐藏 位置而不能自由滑动， 弹性凸起 14a、 14b与定位凹口 214a、 214b之间的接触配合如图 17 所示， 其特点是定位凹口 214a、 214b形成在滑动件 21上， 并随滑动件 21移动， 而弹性凸 起 14a、 14b形成在壳座 1上。 可替代附图所示的凹口移动方案的是弹性凸起移动方案， 其 结构是： 定位机构包括一对形成在壳座 1 上的定位凹口 （图中未示出） 和一对形成在滑动 件 21上的弹性凸起 （图中未示出） ， 当滑动件 21处在隐藏位置时， 两个弹性凸起分别进 入两个定位凹口并与两个定位凹口弹性接触， 致使滑动件 21被限制在隐藏位置而不能自由 滑动。 附图所示的定位机构仅限制滑动件 21在隐藏位置不能自由滑动， 不难想象， 如果需 要限制滑动件 21在隐藏位置和工作位置都不能自由滑动， 则可用以下两种凹口移动方案替 代附图所示的实施方案：一种是定位机构包括两对形成在滑动件 21上的定位凹口 214a、214b 和一对形成在壳座 1上的弹性凸起 14a、 14b , 第一对定位凹口 214a、 214b对应于滑动件 21处在隐藏位置时分别与两个弹性凸起 14a、 14b接触， 致使滑动件 21被限制在隐藏位置 而不能自由滑动， 而第二对定位凹口 （图中未示出） 对应于滑动件 21处在工作位置时分别 与两个弹性凸起 14a、 14b接触， 致使滑动件 21被限制在工作位置而不能自由滑动。 另一 种是定位机构包括两对形成在滑动件 21上的定位凹口 214a、 214b和两对形成在壳座 1上 的弹性凸起 14a、 14b , 当滑动件 21处在隐藏位置时， 第一对弹性凸起 14a、 14b分别进入 第一对定位凹口 214a、 214b并与两个定位凹口 214a、 214b弹性接触， 致使滑动件 21被限 制在隐藏位置而不能自由滑动， 当滑动件 21处在工作位置时， 第二对弹性凸起 （图中未示 出） 分别进入第二对定位凹口 （图中未示出） 并与两个定位凹口 214a、 214b弹性接触， 致 使滑动件 21被限制在工作位置而不能自由滑动。 可将上述三种凹口移动方案归纳为： 定位 机构包括至少一对形成在滑动件 21上的定位凹口 214a、 214b和至少一对形成在壳座 1上 的弹性凸起 14a、 14b , 当滑动件 21 处在隐藏位置或工作位置时， 同一对的两个弹性凸起 14a、 14b分别进入同一对的两个定位凹口 214a、 214b并与这两个定位凹口 214a、 214b弹 性接触， 致使滑动件 21被限制在隐藏位置或工作位置而不能自由滑动。 类似的， 参照上述 三种凹口移动方案不难归纳出可替代三种凹口移动方案的三种弹性凸起移动的方案： 定位 机构包括至少一对形成在滑动件 21上的弹性凸起 （图中未示出） 和至少一对形成在壳座 1 上的定位凹口 （图中未示出） ， 当滑动件 21处在隐藏位置或工作位置时， 同一对的两个弹 性凸起分别进入同一对的两个定位凹口并与两个定位凹口弹性接触， 致使滑动件 21被限制 在隐藏位置或工作位置而不能自由滑动。 弹性凸起移动方案的特点是弹性凸起形成在滑动 件 21上并随滑动件 21移动， 而定位凹口形成在壳座 1上。
参见图 5、 12、 14， 锁定机构 2的滑动件 21包括一个第一面 215a、 一个与第一面 215a 平行的第二面 215b、一个与第一面 215a平行的第三面 215c、两个平行的长侧面 216a、 216b 和至少两个短侧面 217a、 217b , 第一面 215a、 第二面 215b、 第三面 215c形成滑动件 21的 阶梯形的板状体结构， 长侧面 216a、 216b和短侧面 217a、 217b封闭连接构成板状体的周 边， 即形成由多个面组成的如图 5、 12和图 14所示的阶梯形的板状体结构。 所述的第一面 215a朝向断路器 10的外侧面 103a或 103b， 在手柄锁定装置安装到断路器 10上后， 第一 面 215a与断路器 10的侧面 103a或 103b留有间隙， 使侧面 103a或 103b不妨碍滑动件 21 的滑动。 所述的第二面 215b与壳座 1的外表面 12平行， 并且低于壳座 1的外表面 12， 即 第二面 215b在外表面 12上成凹下的结构， 以保证滑动件 21在手柄锁定装置安装到安装轨 (图中未示出） 后不受安装轨上的相邻的其它终端电器 （图中未示出） 挤压而影响滑动。 所述的第三面 215c朝向壳座 1的内表面 16， 并与内表面 16之向留有间隙。 在所述的第一 面 215a与第二面 215b构成的板状体上， 设有如图 5、 12所示的矩形凹槽结构的门洞 211， 凹槽的开口与第一面 215a衔接， 在凹槽的底面上设有与凹槽贯通的挂锁孔 219 (如图 14所 示） ， 门洞 21 1的边框上分别设有与横枢门 22的横枢连接的横枢孔 210a、 与竖枢门 23的 竖枢连接的竖枢孔 210b (如图 7、 8所示）。销孔 218设在所述的第一面 215a与第三面 215c 构成的板状体上， 销孔 218与限位机构的滑动销 213 固定连接； 或者槽孔在所述的第一面 215a与第三面 215c构成的板状体上， 该槽孔与限位机构的滑动销 （图中未示出， 仅适用于 前面所述的替代附图所示实施例的限位机构的结构方案） 滑动配合。 在两个长侧面 216a、 216b的上部设有一对与壳座 1上的一对滑槽 12a、 12b滑动配合的滑块 212a、 212b , 或者， 在所述的两个长侧面 216a、 216b的上部设有一对滑槽， 滑槽与壳座 1上的一对滑块 （图中 未示出， 仅适用于前面所述的替代附图所示移动副机构的结构方案） 滑动配合。 一对定位 凹口 （214a、 214b ) 设置在如图 5、 12和图 14所示的两个长侧面 216a、 216b上； 或者， 两对定位凹口设置在两个长侧面 216a、 216b上 （图中未示出， 仅适用于前面所述的替代附 图所示的定位机构的凹口移动方案） ； 或者， 至少一对弹性凸起设置在两个长侧面 216a、 216b上（图中未示出，仅适用于前面所述的替代附图所示的定位机构的弹性凸起移动方案）。
所述的横枢门 22的厚度加竖枢门 23的厚度之和应小于或等于门洞 211 的深度， 门洞 21 1的深度也就是滑动件 21上的矩形凹槽的深度， 以使横枢门 22和竖枢门 23在合拢状态 下完全收回到门洞 21 1 内 （如图 4、 1 1所示） ， 确保横枢门 22和竖枢门 23不妨碍滑动件 21的正常滑动。 挂锁孔 219对着竖枢门 23， 也就是在竖枢门 23被收回到门洞 211 内的状 态下， 竖枢门 23遮挡 （完全或部分遮挡）着挂锁孔 219， 使挂锁动作随带打开横枢门 22和 竖枢门 23。 具体过程为： 当挂锁 3的锁环 31的端头从挂锁孔 219伸入到门洞 211后， 自然 推动对着的竖枢门 23向断路器 10的方向转动， 竖枢门 23的转动推动横枢门 22向断路器 10的方向转动， 直到横枢门 22和竖枢门 23完全打开到位后， 锁环 31 的端头便可从门洞 211伸出并与挂锁 3入扣上锁。 由于采用了上述的横枢门 22、 竖枢门 23以及挂锁孔 219与 滑动件 21之间的优化集成结构， 所以使本发明的锁定机构 2不仅操作方便、 锁定可靠， 而 且还具有结构空间最小化的优点。
下面结合附图 1至 21， 分别说明本发明的模数化终端电器的手柄锁定装置的第一实施 例与第二实施例不同的实施方式。
参见图 1至 7和图 14至 21所示的本发明的模数化终端电器的手柄锁定装置的第一实施 例， 手柄锁定装置可通过转换所述连接机构的预留孔 101a、 101b和弹性倒钩 l la、 l ib 的 位置结构可选择地实现三种不同安装方式： 第一种是壳座 1只允许固定安装在断路器 10外 壳的左边的外侧面 103a上， 第二种是壳座 1只允许固定安装在断路器 10外壳的右边的外 侧面 103b上， 第三种是壳座 1可互换地固定安装在断路器 10外壳的左边的外侧面 103a或 右边的外侧面 103b上。 在选择第一、 二种安装方式时， 连接机构的弹性倒钩 l la、 l ib与 预留孔 101a、 101b之间的位置结构需满足两个基本条件： 一是满足弹性倒钩 l la、 l ib与 预留孔 101a、 101b之间的卡接配合要求； 二是满足在断路器单个外侧面 103a或 103b上安 装的锁定机构 2与断路器 10的手柄 102之间的锁定配合的要求。 图 3、 4、 7所示的安装方 式为右侧安装， 即由横枢门 22的第一侧沿 221a与手柄 102接触配合， 不难想象， 由于横 枢门 22对称于装配基准线 B， 即第一侧沿 221a与第二侧沿 221b按对称于装配基准线 B设 置， 所以在手柄锁定装置固定安装在断路器 10的左边的侧面 103b上的左侧安装方式下， 则由横枢门 22的第二侧沿 221b与手柄 102接触配合 （图中未示出） 。 然而， 在选择第三 种安装方式时， 连接机构的弹性倒钩 l la、 l ib与预留孔 101a、 101b之间的位置结构不仅 需满足前述的两个基本条件， 而且还需满足第三个条件， 即锁定机构 2在两个外侧面 103a、 103b上的安装都要满足锁定机构 2与断路器 10的手柄 102之间的锁定配合的要求。 因而， 在选择第三种安装方式时， 连接机构的弹性倒钩 l la、 l ib与预留孔 101a、 101b之间的结 构还需在前述的结构方案的基础上采用以下位置结构方案， 参见图 2所示的标注号为 20和 20 ' 的断路器 10的手柄锁定装置表示同一个模数化终端电器的手柄锁定装置， 不过在此仅 从描述清楚出发， 将在拼装到断路器右边的外侧面 103a上的本发明的手柄锁定装置标注为 20， 对应地将拼装到断路器左边的外侧面 103b上的锁定装置标注为 20 ' 。 参见图 2至 4， 所述的断路器 10的外壳的两个外侧面 103a、 103b上分别设有至少一对预留孔 101a、 101b, 同一对的两个预留孔 101a、 101b对称于连接机构的装配基准线 B， 并且壳座 1上的同一对 的两个弹性倒钩 l la、 l ib也对称于连接机构的装配基准线 B， 以使壳座 1能互换地安装在 外侧面 103a或侧面 103b上。 所述的装配基准线 B是将滑动件 21安装到壳座 1后、 滑动件 21沿手柄锁定装置的高度方向 Y的中心线， 也是横枢门 22安装到滑动件 21上后、 横枢门 22沿手柄锁定装置的高度方向 Y的中心线，所以装配基准线 B是由滑动件 21及其上的横枢 门 22安装到壳座 1上后自然形成的。 不难想象， 所述的两个预留孔 101a、 101b, 两个弹性 倒钩 l la、 l ib 对称于连接机构的装配基准线 B， 其实就是指滑动件 21、 横枢门 22、 预留 孔 101a、 101b和弹性倒钩 l la、 1 lb都各自按装配基准线 B对称设置， 这样， 手柄锁定装 置不管安装在断路器 10的左边的侧面 103a还是右边的侧面 103b上， 滑动件 21及横枢门 22在断路器 10的宽度方向 X上的位置是不变的， 即锁定机构 2在断路器 10的宽度方向 X 上相对于手柄 102的位置是不变的， 从而实现了手柄锁定装置可互换地安装在断路器 10的 左边的侧面 103a或右边的侧面 103b上。
参见图 1至 7和图 14至 21所示的本发明的模数化终端电器的手柄锁定装置的第一实 施方式， 手柄锁定装置还可通过转换连接机构的预留孔 101a、 101b, 弹性倒钩 l la、 l ib与 断路器 10的手柄 102转轴 101的轴心线 0的位置结构，可选择地实现两种不同的锁定方式： 一种是只具有 OFF状态锁定或 ON状态锁定的单一锁定方式； 另一种是可兼容 OFF状态锁定 与 ON状态锁定的锁定方式。 在选择第一种仅作 OFF状态锁定的锁定方式时， 所述的锁定机 构 2相对于断路器 10的安装位置只需满足锁定机构 2与断路器 10处于 OFF状态下的手柄 102之间的锁定配合的要求；但在选择第二种可兼容 OFF状态和 0N状态锁定的锁定方式时， 所述的锁定机构 2相对于断路器 10的安装位置不仅需满足锁定机构 2与断路器 10处于 OFF 状态下的手柄 102之间的锁定配合的要求， 还需满足锁定机构 2与断路器 10处于 ON状态 下的手柄 102 之间的锁定配合的要求。 因而， 在选择第二种锁定方式时需采用以下位置结 构方案： 所述的滑动件 21对称于装配基准线 B， 装配基准线 B与断路器 10的手柄 102的转 轴 101的轴线 0 (如图 21所示）相交， 以使手柄锁定装置兼容 OFF状态锁定或 ON状态锁定。 不难想象， 装配基准线 B与手柄 102的转轴 101的轴线 0相交， 其实就是利用了断路器 10 所固有的手柄 102的 OFF位置与 0N位置对称于轴线 0的位置结构特征， 使手柄 102的 OFF 位置与 ON位置对称于装配基准线 B， 这样， 由于滑动件 21、 横枢门 22上的第一侧沿 221a 与第二侧沿 221b、 手柄 102的 OFF位置和 0N位置都分别相对于装配基准线 B对称设置， 所 以使横枢门 22上的第一侧沿 221a与处于 OFF状态下的手柄 102接触配合（如图 1、7所示）， 横枢门 22上的第二侧沿 221b与处于 0N状态下的手柄 102接触配合 （图中未示出） ， 从而 实现手柄锁定装置兼容 OFF状态锁定或 0N状态锁定。 在滑动件 21处于隐藏位置状态下， 断路器 10的手柄锁定装置在高度方向 Y和宽度方向 X上的外形尺寸等于或小于模数化标准 统一规定的尺寸。 基于本发明的具有上述三种不同安装方式和 /或两种不同锁定方式的手柄 锁定装置的产品， 可广泛适用于各种模数化终端电器， 包括断路器、 隔离 （器） 开关、 熔 断器、 漏电模块、 附件 （辅助、 欠压、 分励等） 单元等。
实践中， 有的断路器如果在 0N状态锁定操作手柄， 则会影响断路器的故障跳闸， 而根 据附图 8至 13所示的模数化终端电器的手柄锁定装置的第二实施例， 该锁定装置可通过在 锁定机构的横枢门上增加一个凸耳 220， 实现禁止在 0N状态锁定的功能， 适用于禁止在 0N 状态锁定的模数化终端电器。 具体地说， 参见图 8至 13， 锁定装置的横枢门 22的第二侧沿 221b上设有凸耳 220， 滑动件 21的门洞 211的矩形凹槽的一侧边缘上设有容纳凸耳 220的 凹坑 220a， 在横枢门 22合拢并收回到门洞 211 内的状态下， 凸耳 220完全进入凹坑 220a 内， 使横枢门 22不妨碍滑动件 21 的滑动。 本发明的模数化终端电器的手柄锁定装置的第 二实施方式， 由于横枢门 22的第二侧沿 221b上增设了凸耳 220， 从而使第二侧沿 221b及 其上的凸耳 220与第一侧沿 221a不相对称， 所以第二实施例的手柄锁定装置不能采用上述 的关于预留孔 101a、 101b ,弹性倒钩 l la、 l ib对称于连接机构的装配基准线 B的结构方案， 即第二实施例不能实现手柄锁定装置可互换地安装在断路器 10 的左外侧面 103a或右外侧 面 103b上的安装方式。 设有凸耳 220的第二实施例增强了禁止在 0N状态下对模数化终端 电器执行手柄锁定的功能， 因而凸耳 220的结构不能用于第一实施例， 但由于滑动件 21上 的凹坑 220a专用于容纳凸耳 220， 所以图 12所示的第二实施例的滑动件 21可以适用于第 一实施例。
本发明的模数化终端电器的状态锁定装置不限于附图所示实施例的描述。通过选择采用 上述的与安装方式相关的位置结构方案或者与锁定方式相关的位置结构方案或者与禁止在 0N状态锁定的凸耳 220的形状结构方案， 可实现本发明的模数化终端电器的手柄锁定装置 的丰富的产品型号序列， 其功能可以包括： 只具有 OFF状态锁定功能并禁止在 0N状态下执 行锁定操作； 兼容 OFF状态锁定和 0N状态锁定功能； 仅可单侧面 （左边的外侧面 103a或 右边的外侧面 103b ) 拼装； 可兼容双侧面拼装等等。 然而， 各种型号的产品的零部件除了 壳座 1的弹性倒钩 l la、 l ib的位置和横枢门 22的形状需选定外， 其它均可通用。
