Detailed Introduction

This automotive connector housing series adopts two core high-performance flame-retardant engineering plastics to fit different vehicle working temperature environments.

LCP material possesses ultra-low thermal expansion coefficient and high-frequency insulation, applied to compact miniature multi-pin signal connectors inside engine cabins to avoid terminal position offset under long-term high-temperature operation. V0 flame-retardant glass-filled PBT provides superior mechanical rigidity and wear resistance, suitable for high-current power connectors requiring frequent plugging and locking.

The product lineup includes short single-row terminal blocks, multi-grid long-strip plugs, integrated locking buckle assemblies and modular color-coded shells. Different colors (green, yellow, red, orange, gray, black, blue, white) are customized to distinguish power, signal, ground and high-voltage circuits for fast assembly inspection. Each housing integrates precise pin positioning slots, anti-reverse fool-proof structures and built-in snap locks to realize zero-gap matching with metal conductive terminals. Optimized thin-wall melt flow mold design effectively eliminates shrinkage, warpage and flash defects during high-temperature plastic injection molding.

Complete Production Workflow

1. Custom precision mold core processing: 5-axis CNC rough forming, micro sinker EDM for tiny multi-grid pin hole contours
2. Vacuum stress relief heat treatment for mold steel to stabilize cavity dimension 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 for high-temperature engineering plastics with color masterbatch blending
5. Post-molding full 3D coordinate dimensional inspection, burr trimming and high-temperature aging insulation testing

All finished connector housings pass thermal stability aging and flame retardancy verification tests. Custom development is fully supported based on customer terminal layout drawings: pin grid quantity, shell dimension, plastic flame retardant grade, locking mechanism and color scheme can be adjusted according to operating temperature, voltage load and vehicle assembly requirements. The diversified specification series covers miniature 2-pin sensor connectors to multi-row instrument wiring terminal blocks for one-stop matching supply.
