Description

一种信号灯 技术领域
本发明涉及电学领域， 尤其涉及电气装置， 特别是一种改进的信号灯 的结构。

信号灯大量用于电气控制线路中， 用于指示电路工作状态。 信号灯由 壳体、 发光体和信号灯电路板组成， 发光体设置在壳体的前端内， 信号灯 电路板设置在壳体中， 发光体与信号灯电路板连接， 壳体的尾端设置有两 个接线端， 接线端中分别设置有导电体， 导电体与信号灯电路板和按钮通 过导线连接。 现有技术中， 接线端由导电体、 螺钉和压线板构成， 螺钉与 压线板和导电体通过螺紋连接， 接线由螺钉固定在导电体上， 实现接线与 导电体的连接。 这种接线端子结构， 需要利用螺丝刀完成操作， 过程较为 繁琐。 并且， 电气元件工作在振动环境中时， 螺钉容易产生松动， 造成接 线不可靠的故障情况。
发明内容
本发明的目的在于提供一种改进的信号灯的结构， 所述的这种改进的 信号灯的结构要解决现有技术中信号灯接线不方便、 易产生松动的技术问 题。
本发明的这种改进的信号灯的结构， 包括壳体、 发光体和信号灯电路 板， 发光体设置在壳体的前端内， 信号灯电路板设置在壳体中， 发光体与 信号灯电路板连接， 壳体的尾端设置有两个接线端， 任意一个所述的接线 端中均设置有导电体， 导电体与信号灯电路板之间设置有电连接， 其中， 所述的壳体的尾端沿壳体的轴向设置有一个绝缘基座， 绝缘基座的两侧分 别设置有外罩， 所述的两个接线端分别设置在所述的绝缘基座的两侧和外 罩之间， 任意一个所述的接线端均各自包括有一个笼式弹簧和一个拨叉， 所述的笼式弹簧设置在绝缘基座中的凹槽内，所述的导电体由金属板构成， 笼式弹簧与所述的金属板相邻接触， 笼式弹簧一端的金属片内设置有接线 孔， 笼式弹簧的另一端和金属板的一端穿过所述的接线孔， 所述的拨叉通 过其中部的转轴设置在绝缘基座中， 拨叉的一端与笼式弹簧相邻接触， 拨 叉的另一端内设置有凹槽， 绝缘基座与外罩之间设置有操作窗口和接线窗 口， 拨叉另一端的凹槽的开口位置位于所述的操作窗口中， 笼式弹簧一端 金属片内的接线孔的位置与所述的接线窗口对应。
进一步的， 所述的笼式弹簧由一个弯曲的弹性片构成， 所述的弹性片 的一端设置有一个矩形孔， 所述的弹性片的另一端穿过所述的矩形孔并由 弹力作用向矩形孔的一侧内壁方向偏置， 将弹性片围成一个闭合环， 所述 的闭合环包括一个第一弯曲部和一个第二弯曲部， 所述的第一弯曲部和第 二弯曲部均呈弧形弯曲， 连接第一弯曲部上任意两点的直线段均位于闭合 环内， 连接第二弯曲部上任意两点的直线段均位于闭合环内， 第一弯曲部 和第二弯曲部之间的弹性片上还设置有一个第三弯曲部， 连接所述的第三 弯曲部上任意两点的直线段均位于闭合环外， 所述的拨叉由一个绝缘块构 成， 所述的绝缘块位于闭合环的外侧， 所述的绝缘块上包括有一个可移动 侧面， 所述的可移动侧面与闭合环第一弯曲部的外侧相邻， 可移动侧面在 支架中具有一个第一驻留位置和一个第二驻留位置， 所述的第二驻留位置 与闭合环内区域有交叉重叠部分。
进一步的， 拨叉另一端的凹槽呈十字形。
本发明的工作原理是:外部接线穿过笼式弹簧一端金属片内的接线孔， 由笼式弹簧的另一端压紧在导电板上， 实现电连接。 利用外力驱动拨叉， 挤压笼式弹簧变形， 可使笼式弹簧的另一端脱离导电板， 从而获得穿线间 隙。 进一步的， 当拨叉的可移动侧面从第一驻留位置滑动到第二驻留位置 时， 拨叉的可移动侧面进入弹性片的第三弯曲部， 弹性片的形状部分恢复 后将拨叉保持在当前位置， 因此可以解除作用在拨叉上的外力， 利用双手 进行接线操作。 外部接线穿入后， 再以外力作用在拨叉上， 使拨叉的可移 动侧面挤压闭合环变形后从第三弯曲部移出， 再回到第一驻留位置。
本发明和已有技术相比较， 其效果是积极和明显的。 本发明在信号灯 的接线端结构中采用可以转动的拨叉， 通过该拨叉挤压笼式弹簧， 可以实 现快速接线， 解决了现有技术中螺钉接线操作繁琐的问题， 导线始终由弹 簧压紧， 解决了工作在振动环境中时螺钉容易松动的问题， 通过在笼式弹 簧上设置一个朝向闭合区域外侧的弯曲部， 使挤压笼式弹簧的拨叉实现自 锁， 便于双手专注于接线操作。
