Detailed Description

The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific working procedures are given, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1 and 2, the FFC flat cable on-off detection device of the present invention comprises a first flat cable socket 1 and a second flat cable socket 2, wherein the first flat cable socket 1 is used for connecting one end of a flat cable to be detected, and a first pin and a second pin thereof, a third pin and a fourth pin, a fifth pin and a sixth pin thereof, a seventh pin and an eighth pin thereof are respectively short-circuited by a welding method; the second flat cable socket 2 is used for connecting the other end of a flat cable to be tested, a second pin and a third pin, a fourth pin and a fifth pin, and a sixth pin and a seventh pin of the second flat cable socket are in short circuit respectively in a welding mode, the 1 st pin of the second flat cable socket 2 is connected with the first universal meter wire 3 in a welding mode, and the 8 th pin of the second flat cable socket 2 is connected with the second universal meter wire 4 in a welding mode.

In order to facilitate the connection of the multimeter hand, the following two modes can be adopted: connect one respectively at the other end of first universal meter wire 3 and second universal meter wire 4 and be used for connecting the alligator clip of universal meter pointer, perhaps, add universal meter needle fixing base 5 (see fig. 1), be provided with first meter needle jack 6 and second meter needle jack 7 on it, and first universal meter wire 3 is connected with first meter needle jack 6 electricity, and second universal meter wire 4 is connected with second meter needle jack 7 electricity.

In use, as shown in fig. 2, one end of the FFC bus (i.e. 8pin bus) to be tested is inserted into the first bus socket 1, and the other end is inserted into the second bus socket 2. Because the first winding displacement socket 1 and the second winding displacement socket 2 are different in short-circuit mode, at the moment, the first meter pin jack 6-the first universal meter wire 3-the first pin of the second winding displacement socket 2-the 1 st pin of the winding displacement to be detected-the first pin of the first winding displacement socket 1-the second pin of the first winding displacement socket 1-the 2 nd pin of the winding displacement to be detected-the 8 th pin of the winding displacement to be detected-the eighth pin of the second winding displacement socket 2-the second universal meter wire 4-the second meter pin jack 7 form an electrical connection. And then, adjusting the universal meter to an on-off measuring gear, respectively inserting two test pens of the universal meter into the first meter needle jack 6 and the second meter needle jack 7, and judging whether the whole to-be-measured flat cable has a fault or not by judging on-off display of the universal meter. If the universal meter displays the access, the flat cable to be tested has no problem, and if the universal meter displays the open circuit, the flat cable has a fault. In addition, the multimeter is adjusted to an ohm measuring gear, resistance measurement is carried out according to the method, at the moment, the moving part of the accessory can also be moved,

judging whether the resistance value of the flat cable meets the requirement or not and judging whether the resistance value of the flat cable changes in motion.

When the utility model is used, only two ends of the flat cable need to be pulled out from the PCB circuit board, the flat cable does not need to be detached from the module, and the flat cable is effectively prevented from being accidentally damaged; the utility model adopts the design of the crocodile clip or the jack, which is convenient for realizing the quick and convenient connection with the probe of the universal meter; the utility model can directly connect all wire harnesses of the flat cable end to end without measuring the condition of single flat cable for many times, and can complete the detection of the whole flat cable at one time; in addition, the utility model discloses can also judge whether the winding displacement resistance value meets the requirements to and the resistance value of winding displacement changes in the motion.
