Description

车用保险丝监视器
技术领域
本实用新型涉及车辆维修技术领域的一种车用保险丝监视器。
背景技术
汽车在发生电路故障时，应首先检查各电路中的保险丝是否熔断，但目前车用保险丝多采用拔插式保险丝，检查时需要逐个拔下测量才能确定其是否损坏，非常麻烦。
发明内容
本实用新型的目的就是针对现有技术存在的缺陷，提供一种车用保险丝监视器。
其技术方案是：由检测电路和发光指示电路组成；其中在保险丝RD连接蓄电池DC正极的一端连接发光二极管LED的正极，发光二极管LED的负极连接三极管T的集电极，三极管T的发射极经电阻R3搭铁组成发光指示电路；在保险丝RD连接用电器电源端V+的一端连接电阻R1的一端，电阻R1的另一端连接三极管T的基极和电阻R2的一端，电阻R2的另一端搭铁组成检测电路。
本实用新型具有结构简单，制作安装方便，在需要的地方使用，直观的显示保险丝是否损坏，非常方便实用。
附图说明
附图是一种实施例的接收板电路原理图。
具体实施方式
下面结合附图作进一步描述：由检测电路和发光指示电路组成；其中在保险丝RD连接蓄电池DC正极的一端连接发光二极管LED的正极，发光二极管LED的负极连接三极管T的集电极，三极管T的发射极经电阻R3搭铁组成发光指示电路；在保险丝RD连接用电器电源端V+的一端连接电阻R1的一端，电阻R1的另一端连接三极管T的基极和电阻R2的一端，电阻R2的另一端搭铁组成检测电路。
工作原理：当保险丝RD正常时，检测电路中由电阻R1、R2组成分压向三极管T的基极提供正偏电压，三极管T导通，发光二极管LED发光指示保险丝RD工作正常；当保险丝RD熔断后，检测电路无电压提供给三极管T的基极，三极管T截止，发光二极管LED熄灭指示保险丝RD损坏。

Claims (1)
