Detailed Introduction

This automotive signal connector housing series adopts two core high-temperature engineering plastics to match different vehicle working temperature environments.

LCP material owns ultra-low thermal expansion coefficient and high-frequency insulation performance, applied to the inner multi-grid core inserts, avoiding terminal position offset under long-term high-temperature engine cabin operation. V0 flame-retardant glass-filled PBT provides high mechanical rigidity and plug wear resistance, used for outer locking shells that bear repeated assembly and disassembly force.

The product lineup includes assembled double-lock connectors with blue auxiliary buckles and single-piece integrated locking housings in yellow, orange and red, plus independent white rotary lock buckle components. Each housing is designed with precise pin positioning slots and fool-proof anti-reverse structures, cooperating with auxiliary blue lock buckles to form dual anti-loosening protection and prevent terminal retreat caused by vehicle vibration. Different shell colors are used to classify signal circuits for quick assembly inspection. 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 dense tiny 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 with customizable 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 and color scheme can be adjusted according to operating temperature, signal load and vehicle assembly requirements. The standardized compact specification series covers mainstream automotive body control signal wiring harness matching needs.
