Abstract
Provided is a rotary connector device capable of improving the reliability of electric connection. A rotary connector device (1) includes a stator (11), a rotator (12) rotatably attached to the stator (11), and a flexible flat cable group (13) housed capably of being wound and rewound in an annular space (S1) formed between the stator (11) and the rotator (12) around an axis line (x). The FFC group (13) includes a first FFC (41) wound on the inner peripheral side of the annular space (S1), and a second FFC (42) wound on the outer peripheral side with respect to the first FFC (41), having a length in the annular space (S1) longer than that of the first FFC (41). The second FFC (42) includes both conductors (42-1b to 42-1e) constituting an airbag circuit and a conductor (42-1f) constituting a horn circuit.
Claims6
A rotary connector device comprising:
- a stator;
- a rotator rotatably connected to the stator;
- and
- a flexible flat cable group housed capable of being wound and rewound in an annular space between the stator and the rotator,
- the flexible flat cable group including
- a first flexible flat cable wound on an inner peripheral side of the annular space;
- and
- a second flexible flat cable wound on an outer peripheral side with respect to the first flexible flat cable, having a length in the annular space longer than that of the first flexible flat cable, the second flexible flat cable including both
- first conductors constituting an airbag circuit;
- a second conductor constituting a horn circuit, and
- a third flexible flat cable wound on an outer peripheral side with respect to the second flexible flat cable, having a length in the annular space longer than that of the second flexible flat cable, wherein the third flexible flat cable includes third conductors constituting a large current circuit through which larger current flows than an airbag circuit.
