Abstract

一种能够测试汽车电路是否通电的检测笔,它是 在已有的绝缘外壳中,测试触头、氖管、弹簧和后盖插 座顺序电连接,安装有夹子的插头可与后盖插座相插 接,它可检测出电路故障之所在,使用方便,结构简 单。

Description

本实用新型涉及一种指示汽车电路是否通电的试电装置。
目前,公知的试电笔是由测试触头,限流电阻、氖管、金属弹簧和手触电极相串联而成,将测试触头与被测物接触,人手接触手触电极,当被测物具有较高电压时,氖管启辉,表示被测物带电,但是它不能测出汽车电路是否处于断路或通路状态。
本实用新型的目的是提供一种汽车电路检测笔,它能够方便地指示汽车电路是否通电。
本实用新型的目的是这样实现的:在绝缘外壳中,测试触头,氖管和弹簧顺序电连接,后盖插座与绝缘外壳的后端相固定,设置有夹子的插头可与后盖插座相插接。当夹子夹住车体(即搭铁)而测试触头触及被测物时,如氖管启辉,则表示电路通电,如不启辉,则表示电路断电。
由于采用上述方案,可方便的测出汽车电路是否通电,查出电路故障之所在,结构简单,使用方便。
下面结合附图和实施例对本实用新型做进一步说明。
图1是本实用新型的构造图。
图中1、测试触头 2、绝缘外壳
3、氖管 4、弹簧
5、后盖插座 6、插头
7、电线 8、夹子
在图1所示的实施例中,测试触头(1),氖管(3)弹簧(4)和绝缘外壳(2)后端的后盖插座(5)依次相串联,插头(6)通过电线(7)与夹子(8)相连接,并可同后盖插座(5)相插接。
