Security Component - Clock Spring
The clock spring is a critical electrical rotary connector used in automotive airbags, installed beneath the car’s steering wheel. It serves as a highly reliable current-transmitting device connecting two components that rotate relative to each other. Primarily composed of a flexible flat cable, a housing designed for rotational movement, wire harnesses (conductive lead wires), and connectors, the clock spring ensures seamless electrical connections for essential components like the driver-side front airbag and horn switch during the left-to-right rotational motion of the steering wheel. In automotive airbag systems, the clock spring plays a vital role in transmitting electrical signals and completing circuits, enabling the proper functioning of the airbag's Electronic Control Unit (ECU) after a collision.
