auto wiring harness plugs

This batch of auto wiring harness plugs is fully designed to guarantee safe and stable circuit connection for vehicles, perfectly matching the wiring system of passenger cars, commercial vehicles and refitted cars. We adopt high-quality environmentally friendly flame-retardant materials and thickened pure copper conductive terminals to produce these auto wiring harness plugs in strict accordance with automotive-grade manufacturing standards.
They feature high temperature resistance, aging resistance, wear resistance, as well as excellent waterproof, dustproof and anti-vibration performance, adapting well to harsh working conditions such as high temperature in engine compartments, bumpy driving and outdoor rain and snow weather.
With smooth and firm plugging feeling, these auto wiring harness plugs fit perfectly with original car interfaces. They deliver stable conductivity with low resistance and no overheating, effectively avoiding poor contact, short circuit and power failure risks during driving. Every piece goes through rigorous production and testing procedures to ensure stable quality and long service life.
Widely applied in vehicle supporting, wire harness processing, maintenance replacement and circuit upgrading, our auto wiring harness plugs are easy to install and highly compatible, becoming the first choice for auto repair shops, modification stores and auto parts suppliers.
Production Process of Auto Wiring Harness PlugsRaw material inspection: Conduct testing on plastic shells, conductive terminals and sealing parts to meet environmental protection and strength standards.Terminal stamping and plating: Copper terminals are precisely stamped and partially tin-plated or gold-plated to enhance conductivity and oxidation resistance.Terminal crimping: Wires and terminals are precisely crimped by automatic machines to reach qualified tension and resistance.Housing injection and assembly: Plug shells are injection molded, equipped with buckles, waterproof rubber rings and locking structures.Finished product assembly: Install terminals into the shell and complete the matching assembly of male and female heads.Air tightness and waterproof test: Check sealing performance to prevent water and dust ingress.Electrical performance test: Detect conduction, resistance and insulation to rule out short circuit and open circuit.Aging and vibration test: Simulate real vehicle working environment to verify durability.Full appearance inspection and packaging: Check size, color difference and defects, then pack qualified products into warehouse.
