Through-hole rubber parts for body
Since the through-hole rubber parts are installed with the wiring harness all over the body, the sample used in the test is a wire harness assembly with pre-installed rubber parts. For body through-hole rubber parts, in addition to meeting the characteristics of waterproof, sound insulation, temperature resistance, ozone resistance and chemical resistance, it is also an important control index for the insertion and extraction force performance of whether to install the lining. For the wiring harness assembly passing through the four doors and the luggage compartment lid, since these parts have opening and closing actions in actual use, it is necessary to perform a separate bending test of the rubber parts and test the voltage drop effect of the wires.
