“The design of airbags and seat belts has become increasingly complex over the past 20 years. These safety systems are difficult to install during vehicle assembly, so fail-safe Squib-based mating interfaces are essential,” explains Benoit Lehaut, Product Manager for the global market at Molex. He adds, “The AK-2 Squib interface ensures stable connections with protected contacts and reduces the risk of bent pins and the associated replacement costs that can result from an incorrect airbag connection. The new generation of AK-2 Squib connectors allows for one-step mating with very low force and meets stricter design requirements, improving assembly conditions.”.
The unique ergonomic design of the Squib AK-2 prevents the connector from snagging on holes and wires inside the car or on the seat belt harness. Thanks to the integrated, high-locking CPA (Connector Position Assurance) button, the connector can be easily and securely attached in a single step, preventing premature locking before mating. The CPA button can be manually operated by grasping it between two fingers and pulling it back to the pre-locking position—no tools required.
The soldered connection improves electrical performance while maintaining low and stable contact resistance under extreme temperature and vibration conditions throughout the vehicle's lifecycle.
Available in multiple wiring configurations, the AK-2 Squib Interconnect System offers a reliable solution that meets the requirements of major OEMs, ensuring compatibility with bidirectional interface codes 1, 2, and 3, as defined in the international industry specifications ISO-TS 19072-4 and USCAR 999-U-002-1-Z03 (RevA00).
