Abstract

本实用新型设计了一种在带电情况下,人与灯头接触不会发生触电伤亡事故的自动断电保险灯头,对于卡口灯头其特征是:弹簧套在下触点上方,下触点上方的固定板开有孔,上触点簧片位于开孔固定板上方;螺纹口灯头其特征是:触点位于簧片顶端,灯头顶端开有孔。

Description

本实用新型属一般照明用灯装置零部件,具体地说是一种自动断电保险灯头。
现有灯头其特点是电源直通灯头,接通电源后灯头上所有导电金属的裸露部分都带电,及易触电,发生人生危险。
本实用新型的目的是设计了一种在带电情况下,人与灯头接触,也不会发生触电伤亡事故的自动断电保险灯头。
本实用新型技术解决方案:
卡口灯头其特征是:弹簧套在下触点上方,下触点上方的固定板开有孔,上触点簧片位于开孔固定板上方;
螺纹口灯头其特征是:触点位于簧片顶端,灯头顶端开有孔。
本实用新型的优点是灯头在接通电源不装灯泡之情况下,灯头上任何导电金属裸露部份都不带电(电源被自动切断),任人如何接触摆弄安全无误、毫无关系,而当你装上灯泡后又能立即亮灯照明(自动接通电源),它无须人们有无用电知识,不计较人们如何疏忽大意,黑暗中摸寻灯头安装灯泡等,确保了人类用电人身安全及其消除了人们恐惧心理。
图1是本实用新型卡口式自动断电保险灯头示意图。
图2是本实用新型螺口式自动断电保险灯头示意图。
下面结合附图对本实用新型作进一步描述:
卡口灯头:
当装上灯泡时由于灯泡的推力使(正付极)下触点2内的弹簧3收缩(正付极)下触点上移与上簧片触点1接触,接通电源,电流进入灯泡亮灯照明。
当折下灯泡时,由于推力消逝弹簧3张开推动(正付极)下触点2下移与上簧片触点1分离、切断电源使(正付极)下触点2(裸露导电之金属)处无电状。
螺纹口灯头:
当装上灯泡时由于灯泡旋转上移,灯泡顶端正极触点推动簧片触点2上移经灯头体顶端孔与上正极触点1接触,接通电源亮灯照明。
当折下灯泡时,由于推力消失,簧片触点2回位与上正极触点1分离,切断电源使灯头所有裸露导电金属处无电状。
