电子声光汽车电路检测器
摘要：
本实用新型涉及电路检测器，解决检测汽车电路问题。正极金属探头位于前部，其前端露出塑料壳外，其后端连接整流二极管D1，经限流电阻R1后联接电解电容C及集成稳压块IC。集成稳压块IC再接限流电阻R2及蜂鸣器FMQ，于限流电阻R2端及蜂鸣器FMQ端并联连接发光二极管D2、D3，然后发光二极管D2、D3另端、集成稳压块IC一端，蜂鸣器FMQ一端及电解电容C一端皆联接至负极，构成回路，并于塑料壳后端设有蜂鸣器出声孔，发光二极管显示点及连接鱼型夹的出线孔及其导线。用于检测电路。
摘要（英）：

The utility model relates to a circuit detector, solving the problem that the circuit of an automobile is detected. The metallic probe of a positive electrode is positioned at the front part; the front end of the metallic probe is exposed out of a plastic case; the back end of the metallic probe is connected with a rectifying diode D 1, and is connected with an electrolytic capacitor c and an integrated voltage-stabilizing block IC via a current-limiting resistor R 1; the integrated voltage-stabilizing block IC is connected with a current-limiting resistor R2 and a buzzer FMQ; LEDs D2 and D3 are connected in parallel at the end of the current-limiting resistor R2 and the end of the buzzer FMQ; the other end of the LED D2, the other end of the LED D3, one end of the integrated voltage-stabilizing block IC, one end of the buzzer FMQ and one end of the electrolytic capacitor C are connected to a negative electrode, and thus a circuit is formed. The back end of the plastic case is provided with the sounding hole of the buzzer, the display points of the LEDs, a coil-out hole which is connected with a fish-shaped clip and the conducting wire of the coil-out hole. The utility model is used for detecting circuits.
