The internal Wiring Harness of the car is very complex. It can be said that it is even more difficult to efficiently and accurately test its electrical performance. In terms of the connection between the wiring harness terminal and the wire, it is necessary to detect the crimp connection between the terminal and the wire, and the conductor connection. , Insulation layer connection, Insulation crimp with sealing plug, Rib connection, Connection strength, Voltage drop, Solder connection, etc. It can be seen how necessary a suitable harness tester is.
When testing the wiring harness, what parameters should we mainly pay attention to? In what ways will we judge whether the wiring harness is qualified?
Mainly detect its rated voltage, rated current, temperature rise, contact resistance, insulation resistance, electric strength, withstand current cycle and other indicators. Mechanical properties We can detect its insertion force, pull-out force, terminal retention force, hooking strength, unlocking force, mechanical impact resistance and other indicators. Environmental performance can detect air tightness, water resistance, salt spray resistance, heat aging, oil resistance, etc. Among them, similar to the connection of the insulation layer, the wiring harness of the car cab can be tested by bending the wiring harness during the wiring harness assembly process, so how to test whether the current of the wiring harness of the car is connected? How to quickly judge whether the wiring harness is on or off? Common tools for Wire Harness testing In the process of our daily testing of wire harnesses, we will first use steel tape measure, inspection tool and protractor, which can help engineers to carry out the connection test of terminal and wire, insulation lamination bending test, conductor crimping area cross-sectional test , connection strength test, voltage drop test and other tests. The above is the specific introduction on how to use the wire harness tester to judge whether the current of the car wiring harness is on or off.
