SURGE TESTING DEVICE FOR VEHICLES CAPABLE OF SAVING COSTS THROUGH A WIRE HARNESS SEPARATION STRUCTURE

摘要

PURPOSE: A surge testing device for a vehicle is provided to increase the reliability of the test and offer an effect of improving convenience and saving costs by forming a power line of a wire harness and a ground line in a separable structure.;CONSTITUTION: A surge testing device for a vehicle comprises a load box(100), a wire harness(200), and a surge tester(300). The load box is a test equipment prepared to add an electric load which is exactly alike to a vehicle which applies a test target part(10), and is structured differently for each vehicle in which the test target part is being applied. The wire harness directly connects the test target part and the load box. The wire harness comprises a power line(241) and a ground line(242) consisting of a separable structure. The power line of the separable structure and the ground line are formed by comprising an auxiliary wiring(240) in addition to a main wire(210). The surge tester(300) applies the surge voltage much higher than the used voltage of the test target part in an extremely short time, and analyzes an output waveform of the test target part.;COPYRIGHT KIPO 2013;[Reference numerals] (10) Test target part; (100) Load box; (300) Surge tester
