An air squib ring is typically associated with the airbag system in cars. The more common name for this component is the clock spring (or clockspring). It is a crucial part of the steering wheel mechanism that helps maintain the electrical connection between the car’s steering wheel and various components, such as the airbag, horn, and steering wheel buttons (like audio or cruise control).
The clock spring is a flat, spiral-wound cable that sits inside the steering column, allowing it to expand and contract as the steering wheel turns. When you turn the steering wheel, this part ensures that the connections to the airbag and other steering wheel controls do not get interrupted or damaged. It is called a "clock spring" because its structure resembles a coiled spring, but it is more like a ribbon cable that can unwind and wind back up.
All of these terms refer to the same component or assembly that ensures a secure connection between the steering wheel's rotating movements and the car's stationary electrical system, especially important for airbag deployment.
