Abstract

The invention reveals a wire stock short detection circuit. A wire stock contains a wire stock interface and a plurality of connecting lines, the said wire stock interface has a plurality of wire stock pins, and one connecting line extends out from each wire stock pin correspondingly. The detection circuit includes: a testing interface in butt joint with the said wire stock interface, wherein the said testing interface has a plurality of testing pins, and the said testing pins and the said wire stock pins correspond to each other in a one-to-one manner; a plurality of testing lines which are correspondingly extended from the testing pins of the said testing interface in a one-to-one manner; a plurality of display lamps which are respectively located between the ends, which are away from the said testing interface, of the adjacent testing lines; and a power supply which is in bridge connection with the ends, which are away from the said testing interface, of the two testing lines which are on the two sides in the said plurality of testing lines. The wire stock short detection circuit can detect whether the said connection lines of the said wire stock are short or not directly and can solve the problem of time and energy consuming caused by adopting the method which detects the said wire stock pins one by one.

Description

【Technical field】 [0001] The invention relates to a detection circuit, in particular to a wire short circuit detection circuit. 【Background technique】 [0002] With the rapid development of science and technology, electronic products are more and more widely used in people's daily life, and electronic products usually need to use wires to connect internal or external signals. Therefore, the testing of the wire has become an important research topic. [0003] Taking FPC (flexible circuit board) as an example, it is easy to cause a short circuit after welding, and some wires will cause an internal short circuit after high temperature, and it is not easy to find the short circuit with the naked eye. When using this wire, it is easy to burn the board, etc. bad. When analyzing and testing, it is necessary to take a multimeter to measure one pin (pin) one pin, which is very time-consuming and laborious. [0004] In view of this, it is necessary to develop a wire short circuit d...
