技术领域
本实用新型涉及电路保护， 具体涉及导槽式塑壳断路器。 背景技术
在配电系统中， 为了保障设备的安全运行和操作人员的安全， 都需要 安装断路器。 市场上现有的塑壳式塑壳断路器的安装方式主要有两种： 一 种是采用螺钉直接固定于开关柜、 配电箱内， 此种安装方式需要先在箱体 内打孔， 孔的位置需要与断路器上的螺钉位置对应， 但孔的位置不易校准， 安装程序也比较复杂， 不仅会造成螺钉资源的浪费， 也要花费安装人员大 量的时间和体力， 而且对塑壳断路器进行调换或维修时也极其不便； 另一 种安装方式是在塑壳断路器上接装一安装支架或安装板， 使其能与箱体内 的导轨卡接配合， 安装和调换维修比较便捷， 但此种设置不仅增加了塑壳 断路器的整体制造成本， 也增大了塑壳断路器的体积， 在箱体内也会占据 更大空间， 尤其是在箱体壁厚比较小的情况下， 更不易使用此种设计。
由此可见， 目前的断路器存在安装和维修不便的问题。 实用新型内容
本实用新型所要解决的技术问题是目前的断路器存在安装和维修不便 的问题。
为了解决上述技术问题， 本实用新型所采用的技术方案是提供一种导 槽式塑壳断路器， 包括塑壳断路器主体， 所述塑壳断路器主体的背面设有 导槽， 所述导槽包括平行设置的至少两个槽， 处于两侧的两个槽分别为第 一槽和第二槽， 所述第一槽的外侧壁上设有倾斜卡边， 所述第二槽的外侧

图 4为本实用新型的主视图。 具体实施方式
本实用新型提供了一种导槽式塑壳断路器， 背面自带导槽， 导槽上设 有卡边和弹性卡紧装置， 能将断路器与配电设备箱体上的导轨紧密固定， 需要维修和调换断路器时只需松开弹性卡紧装置就能取下断路器， 结构简 单。 下面结合具体实施例和说明书附图对本实用新型予以详细说明。
如图 1所示， 本实用新型提供的导槽式塑壳断路器包括塑壳断路器主 体 100，本实施例中，塑壳断路器主体 100的背面的导槽包括平行设置的两 个槽： 第一槽 200和第二槽 300， 第一槽 200的外缘设有倾斜卡边 210， 第 二槽 300的外侧壁由若干不连续的挡板组成， 挡板的外侧设有弹性卡紧装 置。弹性卡紧装置包括卡舌 310和卡舌控制部 320，导轨 400的形状与第一 槽 200和第二槽 300匹配，且两边缘分别被倾斜卡边 210和卡舌 310固定。 导轨 400可以是配电设备箱体自带的， 也可以是将螺栓穿过导轨 400的安 装孔临时安装的。
如图 2、 图 3和图 4所示， 本实施例中将弹性卡紧装置的数目设为 2 个， 人们可根据需要对数目进行调整。 每一个卡舌 310 由两个片状的卡舌 板组成， 卡舌 310的伸缩方向与第二槽 300垂直， 卡舌板的端面的形状曲 线为抛物线形， 方便操作人员将导轨 400与第二槽 300卡合， 并且不会出 现卡死现象。 卡舌控制部 320包括两个夹板 321、 拉板 322和弹簧 323， 夹 板 321固定于塑壳断路器主体 100上， 并成对地垂直设置在第二槽 300的 挡板两侧， 拉板 322的两侧分别滑动设置在一对夹板中， 两个卡舌板分别 固定设在拉板 322的内端，拉板 322的外端设有拉手 324，拉板 322上设有
与弹簧 323形状适配的通孔， 弹簧 323置于通孔中， 一端穿过拉板 322固 定连接在第二槽 300的挡板上， 另一端固定连接于远离第二槽 300位置的 通孔的孔壁上。 两个卡舌板可沿挡板两侧的缺口伸缩。
下面具体说明本实用新型的使用方法：
( 1 ) 检査需要安装塑壳断路器的箱体内是否设有导轨， 若没有则需在 箱体上打孔， 孔的位置和数目与导轨 400对应， 然后通过螺栓固定； 若已 安装导轨， 直接进行下一歩操作。
( 2 ) 将导轨 400的上边缘置于第一槽 200内并卡在倾斜卡边 210内， 按压塑壳断路器主体 100的下部，导轨 400的下边缘作用于卡舌 310，使其 回缩， 当塑壳断路器主体到位后， 卡舌 310在弹簧 323的作用下伸出， 卡 住导轨 400的下边缘， 于是塑壳断路器主体 100就被固定在箱体内的导轨 400上。本实用新型中，卡舌 310与导轨 400的下边缘接触的接触面呈抛物 线形， 这种形状与斜面的区别在于： 如果采用斜面结构， 则安装塑壳断路 器时， 导轨 400的下边缘会对斜面产生的一个垂直方向的分力， 该分力容 易使卡舌出现卡死现象； 而采用抛物线形状， 则导轨 400的下边缘产生的 分力沿抛物线的切向布置， 卡舌不会卡死。
另外， 本实用新型采用两块卡舌板替代现有技术中常用的楔形块状结 构， 采用楔形块状结构需要在塑壳断路器的导槽侧壁上开孔， 成型工艺非 常复杂， 而本申请导槽的侧壁仅需要由间隔设置的挡板组成， 大大简化了 成型工艺， 结构更加合理、 简单， 弹性卡紧装置布局更加方便。
( 3 )需要维修和调换断路器时， 拉住拉板 322外端的拉手 324使卡舌 310收缩， 然后将断路器的第一槽 200和第二槽 300脱离导轨 400， 于是塑 壳断路器主体 100就从箱体上拆卸下来了。
由此得知， 本实用新型提供的导槽式塑壳断路器， 背面设有导槽， 通 过弹性卡紧装置将塑壳断路器与配电设备箱体上的导轨紧密固定， 需要维 修和调换断路器时只需松开弹性卡紧装置就能取下塑壳断路器，拆卸方便，
占用空间小， 实用性强， 并能适用于各种箱体， 通用性强。 本实用新型不局限于上述最佳实施方式， 任何人应该得知在本实用新 型的启示下作出的结构变化， 凡是与本实用新型具有相同或相近的技术方 案， 均落入本实用新型的保护范围之内。
