Detailed Introduction

Subdivided Structures & Functional Introduction

1. High-Current Circular Connectors (black cylindrical parts at the top): Multi-hole layout for high-current circuits of vehicle power supply. High-strength shells resist impact during repeated plugging, and the sealing structure adapts to humid & oily environments.
2. Square Multi-Pin Connector Modules (beige, red & blue square housings): Dense pin cavities integrate multiple signal channels. Color-coded housings distinguish power and low-voltage signal circuits, with built-in dual-layer locking structure to prevent loosening caused by vehicle vibration.
3. Continuous Terminal Carrier Strips (long orange & beige strips): Matching carriers for automatic terminal crimping. Neat arrangement improves mass production efficiency of wiring harnesses, and flexible material suits high-speed stamping feeding.
4. Micro Latches & Clips (small black & magenta components): Core secondary locking and anti-retention parts for connectors. Ultra-thin precision structures maintain fatigue resistance after countless plugging cycles.
5. Insulating Support Posts & Spacers (white, orange & blue standoffs): Realize layered terminal insulation and suspended fixation to avoid creepage and short circuits in high-voltage loops, optimizing wiring layout space inside engine bays.
6. Transparent Insulating Gaskets & Films: Internal circuit isolation protection. Transparent design enables visual inspection during assembly, with anti-aging performance to resist yellowing and cracking.

Complete Production Workflow

1. Mold Development: 5-axis CNC rough & finish machining for mold cores + micro EDM for complex locking structures and pin cavities. Molds undergo stress relief heat treatment to sustain stable dimensions over long injection cycles.
2. Cavity Polishing: Multi-stage mirror polishing reduces adhesion of high-viscosity high-temperature plastic melt and ensures burr-free smooth molded surfaces.
3. Specialized Injection Molding: Segmented temperature-controlled molding tailored for high melting point PEEK & PEI, optimizing melt filling of thin-wall and dense fine structures.
4. Post-Processing & Inspection: Full dimensional sampling via 3D coordinate measuring machines, high-temperature thermal aging validation, insulation withstand voltage testing and vibration durability testing before delivery.

Application Fields

High-voltage connections for battery pack BMS of new energy vehicles, wiring harnesses for vehicle ECU controllers, sensor connectors inside engine compartments, body electronic wiring assemblies, and chassis waterproof wiring junction components.
