Rapid and reliable flat cable assembly detection device

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.

Description

technical field [0001] The invention belongs to the technical field of instrumentation testing, and in particular relates to a fast and reliable flat cable assembly testing device. Background technique [0002] Flat cables are widely used in modern electronic equipment. The manufacturing process is to press-fit the connectors at both ends of the flat cables, so the connectors will not be crimped in place, the pins will not penetrate the flat cables, resulting in cable breaks, or due to plugging. Skewing of components causes a short circuit between adjacent wires of the flat wire. Once the flat cable is soldered to the electronic device, it cannot be disassembled, so its inspection is very necessary. Existing inspections of flat cables are performed manually, and a multimeter is used to measure on-off and short-circuit. The labor intensity is high and the production efficiency is low, resulting in low inspection quality and reliability. Due to the lack of sufficient analysi...

Problems solved by technology

Existing inspections of flat cables are performed manually, using a multimeter to measure on-off and short-circuit, which is labor-intensive and low in production efficiency, resulting in low inspection quality and reliability

Due to the lack of sufficient analysis of the cause of open circuit and short circuit in some equipment, the design of the test circuit is complex, the operation is cumbersome, and it is prone to false detection and missed detection caused by operational errors.
