Abstract

The invention provides a cable testing device, which includes a cable access unit, a switch unit, a programmable controller, a signal generator, a PLC unit, and a display unit; the cable access unit includes at least one set of paired cables The input interface and the cable output interface; the switch unit is electrically connected with the programmable controller, and is used to select the cable connected to the test device for testing; the programmable controller is electrically connected with the signal generator and the PLC unit, and the signal generator is also connected with the PLC unit. The PLC unit is electrically connected, and the programmable controller is used to control the signal generator to generate the excitation signal, and at the same time control the PLC unit to transmit the excitation signal to the corresponding cable input interface, and is also used to test the cable according to the feedback signal of the cable output interface ; The display unit is electrically connected to the programmable controller. The invention can realize the testing of various mainstream cables, is convenient to operate, the overall testing process can be carried out automatically, the testing time is short, the efficiency is high, and the accuracy rate is high.

Description

technical field [0001] The invention relates to the testing field, in particular to a cable testing device. Background technique [0002] Cables are widely used in various electronic products, especially in servo systems. Multi-core cables are widely used. Cables are an important factor affecting the stability of product systems. Many system failures are caused by cable failures. Therefore, cables Testing plays an extremely important role in the measurement of electronic products. At present, a manual detection method is generally used for cable measurement, that is, a multimeter is used to test the conduction state at both ends of the cable. However, this detection method is inefficient, slow, heavy workload, and error-prone. Therefore, it is very meaningful to design a fast, convenient, automatic and widely used cable testing device to test cables. Contents of the invention [0003] The object of the present invention is to provide a cable testing device, aiming at so...
