How is the process optimized for energy storage power harnesses?

ONE. How is the process optimization of the energy storage power harness? The energy storage power harness conducted air tightness tests on the blind plug in this loose state and found that its waterproof sealing performance was greatly reduced and it was very easy to fall off, with a great risk of water ingress and corrosion. Measures must therefore be taken for process or design optimization. Reason analysis and follow-up measures due to the large size of the plastic shell and sealing is very high, so in the assembly if the operation speed is faster, there is a certain amount of air pressure inside the plastic shell, will make the blind plug by a certain pressure to the outside of the ejection. This blind plug was analyzed, and it was found that some oil stains existed on the outer surface of some blind plugs, which may lead to the possibility of loosening in extreme cases, even if the blind plugs have been assembled and put in place in the wiring harness factory, they are still easily loosened outward by the influence of the internal air pressure when the plastic shells are connected in the assembly line. Improvement Measures: Long-term measures include updating the blind plug tooling to further ensure the installation depth of the blind plugs, and adding process equipment to remove oil from the blind plugs during production to ensure that the blind plugs are less likely to slip out of place. Until the process equipment was in place, a temporary measure was taken to seal the chamber, i.e. a wire with a sealing ring was inserted into the chamber and secured in the chamber by means of a terminal. A plugging test was carried out on the samples after the process optimization measures such as de-oiling, and after 10 plugs on each of the 10pcs samples, no further loosening of the blind plugs was found, so the measures were considered to be effective.
