Description
MEDIUM FOR PROVIDING ELECTRICAL CONNECTIVITY BETWEEN END
TERMINAL CONNECTIONS
TECHNICAL FIELD
[0001] The present invention relates to the field of flexible electronics. More particularly, the present invention relates to medium for providing electrical connectivity between end terminal connections.
BACKGROUND
[0002] In the past decades, many functions have been migrating from their traditional positions on the dashboard onto the steering wheel. For example airbag, heated steering relay switch, horn control, radio controls, phone answering, cruise control operation, and several others have been integrated into steering wheel. The clock-spring or steering rotary connector is a device that allows an electrical connection between two members that are in relative motion with respect to each other. For example, a motion of the steering wheel and the steering column with respect to steering column control module is always rotating or oscillating and the steering column control module is always stationary.
[0003] Typically, clockspring or a steering rotary connector is a device that allows an electrical connection between two members that are in relative motion. In existing systems, a flexible flat cable is wound inside housing which carries an actual electrical connection from horn, cruise control, airbag and the like mounted on steering wheel to the steering column control module or the dashboard. In general, shifting an interface from the dashboard to steering wheel improves driving safety by positioning the most commonly used controls on the steering wheel.
[0004] Furthermore, based on the present requirements of shifting the controls to the steering, the usage number of flexible flat cable in clockspring or steering rotator connector also increases proportionately. This need can be addressed by increasing the cassette size to accommodate more number of flexible flat cables. Increasing the number of flexible flat cables would also increase mechanical cost, frictional problem, SCCM (Steering Column Control Module) size, noise, flexible flat cables rotational problems and the like. Moreover to achieve this, a complex
l
mechanism is required and the number of assembly steps of the clockspring or steering rotator connector also increases.
[0005] In the light of aforementioned discussion there exists a need for using multilayer flexible circuits for use in an existing clockspring or a steering rotary connector.
