Airbag Harness Connector — 24-Position Micro Quadlok Receptacle
The TE Connectivity 284223-3 is a 24-position receptacle from the Micro Quadlok series, purpose-built for automotive safety restraint systems — specifically airbag harnesses where a positive-lock connection is non-negotiable. The lever lock fastening type provides a high-retention mate that resists vibration and accidental disconnect in the vehicle interior. Operating temperature spans -30°C to 105°C, covering the under-dash and seat-belt pretensioner environments where these connectors live.
What the 24 Positions and Lever Lock Mean for the Harness Build
The lever lock engages with an audible click when fully mated, giving the line worker a positive confirmation that the connector is seated. Unlike a latch that can be bumped loose, the lever requires a deliberate squeeze-and-pull action to release, which is the standard for safety-critical restraint circuits. The crimp termination accepts the wire gauge specified in the vehicle's wiring diagram; the female socket contacts are ordered separately and must be crimped with the correct TE application tooling to achieve the required pull-force.
Sourcing and Lifecycle
Stock both halves or neither — the matching male header (plug) with the same lever lock interface is required for a complete mated pair.
