Abstract
The utility model belongs to an electric pulse generating and receiving apparatus, particularly to a short circuit detecting meter for an automobile. The utility model is characterized in that a base electrode of a triode T1 is connected with an output foot 3 of an integrated block 555 through a resistor R5, a collector electrode of the triode T1 is connected with a power supply end A, and an emitter of the triode T1 is connected with an output end B. The output end B outputs a pulse direct current and is connected with a short circuit conducting wire. A signal receiving device is used for receiving a signal of the pulse direct current to judge a short circuit point. The utility model has the advantages of simple structure and safe and convenient operation, and can rapidly find out the short circuit point of the automobile.
Description
The utility model relates to the generation and the receiving trap of electric pulse, specifically a kind of automobile line short trouble somascope.
As everyone knows, car electrics circuit circuit bundle is numerous, distributes wide and mutual the intersection, the fault if circuit is short-circuited, general now employing universal electric meter is manually searched short dot, this short dot mode of searching, time-consuming, effort, efficient are low, and are absolutely unsafe.
The purpose of this utility model just provides a kind of automobile line short trouble somascope that can find short dot accurately, quickly and safely.
For achieving the above object, the utility model is made up of signal generator and signal receiver, and signal receiver is made up of coil (N) high impedance earphone EJ, and signal generator is by integrated package (555), regulator block (T
