Automobile wiring harnesses and connectors are all over the body of the car, connecting various electrical appliances and electronic equipment in the car to transmit electrical signals. Whether the car wiring harnesses and connectors are in good contact directly affects the normal operation of the car and the safety of drivers and passengers; with the continuous development of automotive electronics The development has also put forward higher requirements for the connector: the connector should be more flexible, the insulation degree should be higher, and it can provide better conditions for the conduction of the wire bundle.
Automotive wiring harnesses and connectors need to be tested for the following:
* Conduction, open circuit, short circuit, crossover, instantaneous on-off, withstand voltage, insulation
* Some wiring harness components also need to test inductors, resistors, capacitors, light-emitting diodes, etc.

Solution Details,

On-off test: Through high-precision voltage and current source driving and sampling, judge short circuit/open circuit/open circuit, and whether there is cross/dislocation.

Instantaneous on-off test: Due to the frequent shaking or swaying of the automobile wiring harness during the production and testing process, there will be instant on-off (as shown in the figure below). Requires ultra-high instant-pass sampling speed.

Withstand voltage insulation test: With the popularization of new energy vehicles and the development of new energy vehicle technology, the voltage of lithium electric vehicles has reached more than 1000V. For automotive wiring harnesses and connectors, safety is an unavoidable consideration. Automotive wiring harnesses and connectors usually need to test withstand voltage and insulation, as shown below:
