Description

The Autoliv 627844200C is a high-reliability squib connector designed for automotive safety systems, specifically engineered to deploy airbags and seatbelt pretensioners in collision events. As part of Autoliv’s PyroConnector series, this component ensures fail-safe electrical initiation of pyrotechnic devices through its patented shorting clip technology that prevents accidental ignition during handling or maintenance. The Autoliv 627844200C features a dual-lock mechanism (primary latch + secondary CPA) for positive engagement and vibration resistance exceeding 20g, critical for automotive applications. Its halogen-free thermoplastic housing withstands engine compartment temperatures (-40°C to +150°C) while meeting ISO 12097-2 safety standards for pyrotechnic initiation circuits.

Compatible with 2.8 mm male pins, this connector enables rapid assembly on production lines with audible mating confirmation. The Autoliv 627844200C integrates a gold-plated brass terminal for <5>627844200C for zero-field failures under TL 226 automotive connector standards.

Technical Specifications

Main Features and Advantages

Safety-By-Design: The Autoliv 627844200C‘s automatic shorting clip bridges terminal contacts when unmated, preventing stray current ignition. CPA (Connector Position Assurance) slider provides tactile confirmation of full engagement. Dual-stage locking requires deliberate tool intervention for disconnection.

Robust Performance: Engineered for extreme environments, the connector maintains seal integrity under high-pressure car washes (IP6K9K) and salt spray (ISO 9227). Gold-plated contacts resist sulfurization and oxidation. Vibration-proof latches withstand powertrain resonance frequencies.

Manufacturing Efficiency: Color-coded housings and foolproof polarization enable error-proof assembly. HaloSeal® technology eliminates separate gaskets, reducing parts count. Audible “click” confirms proper mating on production lines.

Long-Term Reliability: Terminal retention force >75N prevents backing-out. Material formulation resists automotive fluids (gasoline, brake fluid, coolant) per SAE J1748. The Autoliv 627844200C exceeds 15-year service life validation per LV 214-1.

Application Field

The Autoliv 627844200C is deployed in critical automotive safety systems:

Driver/Passenger Airbags: Connects to inflator modules in steering wheels and dashboards, withstanding steering column rotation cycles.

Seatbelt Pretensioners: Initiates pyrotechnic tensioning in B-pillar and seat-integrated systems during frontal collisions.

Curtain Airbags: Roof rail installations where temperature extremes (-40°C to +85°C ambient) demand material stability.

Pedestrian Protection Systems: Connects to hood-lift actuators in Euro NCAP-compliant vehicles.

Electric Vehicles: High-voltage isolation design prevents interference from 400V+ traction systems.

Installation and Maintenance

Pre-installation preparation: Verify terminal crimp quality (pull force >50N) using Autoliv-approved tools. Clean connector cavities with IPA to remove molding lubricants. Ensure CPA slider is in pre-lock position before mating.

Maintenance recommendations: Replace after single airbag deployment event. Inspect for terminal fretting every 100,000 km. Use only Autoliv-approved dielectric grease (Nye NYOGEL 760G) for reconnection. Never bypass shorting clip during diagnostics.
