Abstract

本实用新型属于电源插头的改进。其特征是在 插头内的两进线间跨接一电源指示的氖灯泡;它的出 现,给使用者带来方便,可直观了解插座与插头是否 接触良好。其结构简单,易于加工,便于推广。

Description

本实用新型属于电源插头的改进。
常用的各类电源插头,本身均无通电显示功能。即在使用时,插头插入插座后,凭插头本身无法辨别插头与插座导电部分是否已接触良好,给使用者带来不便。
本实用新型的目的是提供一种可使插头插入插座后,即可显示插头与插座导电部分接触情况,具有通电显示功能的电源插头。
本实用新型的技术要点是:在插头(1)内的两进线间跨接一电源指示的发光二极管或氖灯泡ND;当插头插入带电插座,插头(1)上的发光二极管或氖灯泡ND亮,向使用者指示插头与电源接触良好。
本实用新型的出现,给使用者带来方便,可直观了解插座与插头是否接触良好。其结构简单,易于加工,便于推广。
图1为本实用新型的结构示意图。
图2为本实用新型的外形图。
图3为本实用新型的原理示意图。
从图1可见电源指示的小氖灯泡ND跨接到进线插片(2)间,氖灯泡ND可外露于插头(1)上的指示孔(见图2中的标号3)。从图3可见与氖灯泡ND串接有一限流电阻R。

Claims (2)

1、一种带通电指示的电源插头,具有插头和插片,其特征是在插头(1)内的两进线间跨接一电源指示的发光二极管或氖灯泡ND。
2、接照权利要求1所述的电源插头,其特征是与氖灯泡ND串接有一限流电阻R。
