QA2201: 2.2mm Pitch Wire-to-Board BMS Connector
Product Features
The QA2201 is a wire-to-board connector specifically designed for Battery Management Systems (BMS) in new energy vehicles (NEVs).
Series
MX34 Non-Waterproof Connector
Design
Dual-row 2.2 mm wave soldering connector with precise matching between board and wire ends.
Wire-End Housing
Features a bridge structure to prevent deformation and resist accidental unlocking by foreign objects or external forces.
TPA (Terminal Positioning Assurance)
Pre-assembled to simplify installation, reduce user labor and costs, and ensure reliable terminal fixation, improving both lifespan and electrical performance.
Terminals
Quadrilateral body with a two-layer spring contact structure. The internal locking structure of board and wire ends ensures vibration resistance, high retention force, and stable contact performance.

Applicable Standards
Automotive industry standards, USCAR 2.0, QC/T 1067-2017, and other relevant automotive standards.
Application Scenarios
The QA2201 is designed for BMS connection scenarios in new energy vehicles, and is widely used in:
• Automotive BMS systems
• ECUs (Electronic Control Units)
• Other EV battery management applications
• It ensures stable, high-reliability connections in harsh automotive environments.
Production Process
A dual-branch parallel production model is employed, using copper strip base material and injection molding raw materials:
Copper strips are stamped and electroplated to improve conductivity, corrosion resistance, and wear resistance.
Injection molding raw materials are processed simultaneously into connector housings and other components.
Components are combined, followed by pin assembly, CCD inspection, tape-and-reel packaging, and a full-process final inspection.
Qualified products are stored and shipped according to order requirements.
Production Site
The core production base covers injection molding, stamping, and assembly processes:
Injection Molding Workshop
Automated equipment ensures dimensional accuracy and material consistency.
Stamping Workshop
Precision equipment processes copper strip terminals to provide accurate components for electroplating.
Assembly Workshop
Automated production lines integrate online testing devices for assembly and initial inspection, ensuring consistent quality and delivery efficiency.
Package & Transportation
Industrial-grade standardized packaging is used. Products are placed in dedicated cartons and secured on pallets, suitable for forklift handling.
Storage: Retain original factory packaging in a clean, dry, dark warehouse with stable temperature and humidity. Avoid external pressure.
Transportation: Road transport, international express, air freight, or sea freight. Avoid contact with sharp objects or violent impacts. Ensure safe loading and unloading. Packaging materials should be recycled.
QA and QC
The QA2201 is an automotive-grade wire-to-board BMS connector with multiple international certifications, ensuring reliable performance and compliance with industry standards.
