Abstract

The invention relates to a rapid and reliable flat cable assembly detection device which is used for detecting positive and negative design of light emitting diodes through adjacent flat cables and solving the problem of short circuit detection. A complementary design is adopted in short circuit detection circuits at two ends of a flat cable, i.e., the anode of the light emitting diode at one end is connected with a dual-row socket, and the cathode of the light emitting diode at the other end is connected with a dual-row socket. By means of the structures of the short circuit detection circuits, the open circuit detection of a light emitting diode stack is realized, the detection is rapid and convenient as well as accurate and reliable to ensure that the degree of automation in operation of the detection device is greatly improved; and a flat cable assembly checked by using the detection device has greatly improved quality and reliability and working efficiency increased by tens to hundreds of times.
