Self-Rejecting AK2 Squib Connectors Ensure Safety of Airbags
J

apan Aviation Electronics Industry, Limited (JAE) has developed the AK2 standard-compliant MX72A/B Series squib connectors featuring improved workability for automotive airbags.

The AK2 type squib (igniter) connector has been adopted as the standard interface for automotive airbag inflators in Europe and North America, and is growing in popularity globally. However, a lot of these connectors are designed to ensure complete mating by inserting a component called a connector position assurance (CPA) after the connectors are mated, which requires a secondary operation. Also, if the airbag is located in an area where the connector engagement cannot be visually confirmed by the operator, there is a risk of incomplete mating due to mis-insertion of the CPA device. In order to make the installation process faster and more reliable, JAE has developed the MX72A/B Series AK2 squib connectors that ensure a fully reliable connection in a single operation.

The MX72A/B Series are connectors that eliminate incomplete mating with a spring operated self-rejection structure. It provides a positive audible and tactile feedback, which allows for confirmation of complete engagement in a single operation. Therefore, the MX72A/B Series improves workability and reliability of the airbag system by preventing incomplete engagement.

Three mis-mating key options, compatible with USCAR and ISO standards, are available in case multiple connectors are on one board.

In order to improve automotive safety, importance is placed on the introduction of safety features to protect the passengers as well as pedestrians. In addition to the usual driver’s seat and passenger’s seat, airbags are being installed in many other areas of vehicles, such as on the side, the rear seats, and in the front of the vehicle for pedestrian safety. The number of airbags is expected to continue to increase further in the future.
