Detailed Introduction

This automotive connector series adopts two core high-temperature engineering plastics to adapt to various vehicle operating environments.

LCP material has ultra-low thermal expansion coefficient and excellent high-frequency insulation, applied to miniature multi-grid inner cores to avoid terminal offset under long-term high temperature inside engine compartments. V0 flame-retardant glass-filled PBT owns high mechanical rigidity and plug wear resistance, used for outer locking shells that withstand repeated assembly and disassembly force.

The product portfolio consists of assembled dual-lock connectors with blue auxiliary buckles, integrated single-piece locking housings in yellow, red, orange, white and light blue, mini cylindrical sensor plugs, long strip multi-position terminal blocks, circular rubber sealing rings and waterproof positioning stoppers. Different colors are adopted to classify power, signal and ground circuits for fast assembly inspection. The dual-layer locking design formed by main housing and blue auxiliary buckle provides reliable anti-loosening performance to prevent terminal retreat caused by vehicle vibration. Supporting sealing rings and stoppers achieve IP-grade waterproof and dustproof performance for connectors installed on chassis and engine compartments. Optimized thin-wall melt flow mold design effectively eliminates 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 tiny grid pin slots and complex locking contours
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 dimensional inspection, burr trimming, high-temperature aging and waterproof performance testing

All finished plastic components pass thermal stability aging and flame retardancy verification tests. Custom development is supported based on customer circuit layout drawings: pin grid quantity, shell wall thickness, plastic flame retardant grade, locking structure and color scheme can be adjusted according to operating temperature, signal load and vehicle assembly requirements. The standardized multi-color specification series covers mainstream automotive body control, sensor and interior wiring harness matching demands.
