Detailed Introduction

This full automotive connector component series adopts two core high-temperature engineering plastics to fit diverse vehicle operating environments.

LCP boasts ultra-low thermal expansion and superior high-frequency insulation, applied to compact multi-pin signal inner cores and tiny positioning auxiliary parts inside engine compartments, effectively preventing terminal displacement caused by long-term high-temperature exposure. V0 flame-retardant glass-filled PBT features outstanding mechanical rigidity and impact resistance, suitable for large junction housings, cylindrical high-voltage plugs and locking brackets bearing heavy mechanical load and circuit heating risks.

The product portfolio includes all core matching parts for automotive wiring harness systems: long strip multi-grid signal blocks in cyan, green, brown and white, cylindrical high-current power connectors, color-coded modular signal housings, circular waterproof sealing stoppers, terminal locking wedges, anti-retention pins and green locking operation covers. Multi-color differentiation is adopted to distinguish power, signal, ground and high-voltage circuits for fast assembly inspection. Each main housing and auxiliary fitting adopts matched precise clearance to form dual anti-loosening protection, eliminating poor contact induced by vehicle vibration. Optimized thin-wall melt flow mold design solves shrinkage, warpage and flash defects during molding high-temperature flame-retardant plastics.

Complete Production Workflow

1. Custom precision mold core processing: 5-axis CNC rough & finish milling, micro sinker EDM for complex curved profiles and tiny grid pin slots
2. Vacuum stress relief heat treatment for mold steel to stabilize cavity dimensions under continuous high-temperature injection cycles
3. Multi-stage mirror polishing to reduce melt adhesion of LCP/PBT flame-retardant plastic and lower demolding resistance
4. Segmented temperature-controlled precision injection molding with customizable color masterbatch blending
5. Post-molding full 3D coordinate inspection, burr trimming, high-temperature aging and flame retardancy safety tests

All finished plastic components pass thermal stability and vibration anti-loosening aging verification. Custom development is available based on customer circuit layout drawings: pin grid quantity, shell wall thickness, plastic flame retardant grade, locking mechanism and color scheme can be adjusted according to operating temperature, current load and vehicle assembly requirements. The diversified full-spec series provides one-stop supporting supply from miniature sensor signal connectors to new energy vehicle high-voltage power distribution assemblies.
