QA2203: 2.20mm Pitch Multiple Wire Connectors Automotive

QA2203 Series – 2.2 mm Pitch Double-Row Connectors

The QA2203 series is a customized double-row connector designed specifically for high-vibration environments in automotive electronics. Its core advantages include high vibration reliability, precise electrical performance, and comprehensive customization capabilities.

• Construction: The pins are securely embedded in the PBT housing using a double-shot molding process, resisting high-frequency vibrations and preventing poor contact.

• Layout: The 2.2 mm pitch double-row configuration supports multi-circuit signal transmission, with tight control over critical dimensional tolerances.

• Materials: Housing is made of PBT UL94-V0 flame-retardant plastic, and pins are brass with matte tin plating, offering high temperature resistance, aging resistance, and excellent conductivity, meeting the long lifespan requirements of automotive electronics.

Applicable Standards

Automotive industry standards, including USCAR2.0, QC/T1067-2017, and other relevant automotive standards.

Application Scenarios

With high vibration reliability, automotive-grade electrical performance, and extensive customization capabilities, the QA2203 series is suitable for:

Benefits: Provides non-standard layout customization solutions, maintaining precise signal transmission in emergency scenarios and high-vibration testing environments.

The production process uses a dual-branch parallel model for copper strip and injection molding raw materials:

• Copper strips are stamped and electroplated to enhance conductivity and wear resistance.
• Injection molding raw materials are processed into connector housings and other components.
• Components are assembled using pin insertion, followed by CCD visual inspection, tape and reel packaging, and final comprehensive inspection.
• Qualified products are stored and shipped according to orders, ensuring consistent quality throughout the process.

• Packaging: Industrial-grade standardized packaging. Products are placed in corrugated boxes with cushioning pads, secured on pallets, and wrapped with waterproof stretch film.
• Storage: Retain original packaging; store in a clean, dry warehouse with controlled temperature and humidity.
• Transportation: Road, international express, air, and sea freight. During handling, avoid sharp objects, heavy impacts, and ensure safe loading/unloading.

The company has obtained multiple authoritative system certifications, including IATF16949, ISO9001, and ISO14001, covering all aspects of production, management, and service. Multiple utility model patents in connector structure optimization and process innovation provide core support for compliance, quality stability, and market competitiveness.
