Abstract

本实用新型是对现有用电设备中熔断器的一种 改进,由插头与插座组成、主要特征是在插头上铜插 片的两端连接一发光装置,该装置与保险丝并联。根 据保险丝的通与断,直接显示于发光装置中发光体的 发光与否,为熔断器的维修带来便利条件,也不会因 误判而造成不必要的损失。

Description

本实用新型涉及一种熔断器,更具体地涉及一种光显示熔断器。
目前在用电设备中使用的熔断器,由插头和插座两部分组成,在插头的两个铜插片之间接有保险丝。这种熔断器由于插头和插座是闭合使用的,这样就不容易判别保险丝的通断状态,给日常维修带来不便,如果误判,可能还会给正常运行的设备造成损失。
本实用新型的目的在于提供一种新颖的熔断器,这种熔断器能直接显示插头上保险丝的通与断,这不仅对有目的地维修创造便利条件,又能避免误判造成不必要的损失。
本实用新型的目的是这样实现的,一种熔断器,包括插头和插座,其特征在于还包括一发光装置,发光装置的两端与插头的两个铜插片连接,发光装置由发光体和限流电阻组成,两者串联在一起。
本实用新型由于在现有熔断器插头的两端设置了一发光装置,在正常情况下,发光装置两端的电压为零,发光体无光;一旦保险丝断裂,发光装置两端的电压升高,发光体发出亮光,从而直接显示保险丝需要更换,为有目的地更换保险丝创造了有利条件,同时,也不会波及正常运行的熔断器。
下面结合附图和实施例对本实用新型作进一步描述
附图为本实用新型结构示意图
图中:①插头 ②半园头螺钉 ③限流电阻 ④氖灯 ⑤透明盖片 ⑥铜插片 ⑦保险丝
限流电阻③与氖灯④串联组成发光装置,其两端通过半园头螺钉②与插头①两端的铜插片⑥连接,在发光装置上方盖一透明覆盖片⑤,两铜插片⑥之间连接一保险丝⑦,插头①插入插座内(图中未标出)。
本实用新型中,氖灯还可以由发光二极管等发光体代替。
