Abstract

The invention relates to a multi-core cable wire testing device, aiming to solve the problems of low efficiency, easy errors, hardly discovery of poor contact caused by faulty welding between a wire and a terminal, and the like in the prior art. The multi-core cable wire testing device comprises a testing instrument and a vibrator, wherein the testing instrument comprises an operation panel and a testing circuit which is formed by sequentially connecting a multivibrator, a frequency division loop, a sequential output loop and a display loop in series, a power supply supplies power to the multivibrator and the loops, and two testing sockets are respectively connected with the sequential output loop and the display loop. The invention detects a multi-core cable wire under the vibration condition, can not only detect the wiring correction, but also detect whether hidden danger, such as poor contact due to faulty welding, and the like exists.

Description

technical field [0001] The present invention relates to a test method and device, more specifically, the present invention relates to a test method and device for multi-core cables. Background technique [0002] In the production process of servo motors, according to the needs of customers, there are many types of drivers and encoders used, which leads to the need to make multi-core cables with different wiring methods. The quality of the multi-core cable contacts will directly affect Servo feedback, most of the servo faults or encoder alarms are caused by the quality problems of the multi-core cable contacts. The inspection of this multi-core cable usually uses a multimeter to measure each core wire one by one. This method is time-consuming and labor-intensive, and it is easy to miss detection and false detection, which is not conducive to the detection of large batches. [0003] The Chinese Patent Office published a document CN101221207A on July 16, 2008, titled a multi-c...
