Abstract

带发光指示的220V、380V电源插头是直接以发 光的形式显示通电状态的一种插头，属于结构零部件 插头领域。它由金属柱，火线、地线，电阻和发光二极 管组成，在火线与地线之间串接一只100K—150K 电阻和一只发光二极管。它结构简单，显示明了，适 用于电气设备、电工工具等电源插头。

Description

带发光指示的220V、380V电源插头是直接以发光的形式显示通电状态的一种插头，属于结构零部件插头领域。
目前，电气设备、电工工具等电源插头是由两个金属柱（片）和两根导线组成，金属柱（片）插在插座上，与金属柱相连的两根导线接电气设备的电源入。这种插头不能直观反应通电状态。
本实用新型发明的目的在于克服现有技术的缺陷，发明一种带发光指示的220V、380V电源插头。一旦插头接入220V或380V时，发光管亮，即能直观反应通电状态。
本实用新型发明的内容是这样的：带发光指示的220V电源插头是由两根金属柱（片）、两根导线、一个电阻、一个发光二极管组成。它的连接关系是在与两根金属柱分别相连的两根导线之间串接100K－150K电阻和一只发光二极管。带发光指示的380V电源插头是由四根金属柱、三根火线一根地线、三个电阻和三只发光二极管组成，每根火线和地线之间串接一只100K－150K电阻和一只发光二极管。
本实用新型的优点在于它是能直接以发光形式显示通电状态的插头，夜间或在黑暗中指示更为清晰。它结构简单、显示明了。
现在结合附图和实施例对本实用新型做进一步细述。
图1为本实用新型带发光指示的220V电源插头示意图。
图2为本实用新型带发光指示的380V电源插头示意图。
图3为本实用新型带发光指示的220V电源插头外形结构示意图。1为发光二极管管帽。
在以带发光指示的220V电源插头为例，在火、地线之间串接电阻R为100K和发光二极管，发光二极管管帽为φ5。两金属柱（片）之间为30mm，电源插头帽直径为35mm，金属柱（铜柱）为圆形φ4mm，金属柱长为20mm。

Claims (1)
