A multi-head cable scratch resistance test device

Abstract

The invention discloses a multi-head cable scratch resistance test device, the device includes a scratch resistance test body, an electrical cabinet is arranged on one side of the scratch resistance test body, and a servo driver, a differential to collector code are arranged inside the electrical cabinet device, PLC controller, relay, the servo driver is electrically connected to the servo motor, and the PLC controller is electrically connected to the relay. By programming the PLC controller, it is possible to control any scratch-resistant test head to automatically stop counting when the scratch needle touches the sample conductor, and display an alarm message on the operation screen of the man-machine interface without affecting the normal operation and counting of other test heads ; At the same time, by programming the PLC controller, it can be realized that when some test heads are in normal test, other test heads without test samples can be used to test in the middle, without affecting the normal counting of the running test heads. The equipment is easy to operate, easy to understand, and has a long service life, which greatly shortens the test cycle and greatly improves work efficiency.

Description

technical field [0001] The invention relates to a multi-head cable scratch resistance test device, which belongs to the technical field of wire and cable testing. Background technique [0002] The traditional PI / PTFE composite insulated wires and cables for aerospace do not have the performance index requirements for scratch resistance, but with the rapid development of my country's aerospace industry, in order to deal with various harsh aerospace environments, such as vibration, shock It will cause the cable to be scratched, and the scratch resistance performance of the new generation of PI / PTFE smooth composite insulated wire and cable for aerospace is put forward. Whether the insulation or sheath layer of the wire and cable is scratch-resistant is also one of the methods for judging whether the wire and cable can be used for a long time. [0003] Article 10.13 of the national standard GB / T 33343-2016 "Test Methods for Aviation Insulated Wires" requires: Sample test 10 po...

AI Technical Summary

Problems solved by technology

Taking a wire with a wire gauge number of 20 as an example, the average number of cycles during scratching and conducting at room temperature should not be less than 5,000 times, that is, it takes at least 90 minutes to make a test point, while the existing reciprocating scratching test The instrument can only measure one point at the same time, and it takes at least 900 minutes to complete 10 test points. The test cycle is long and the efficiency is low.
