Clock spring and system for transmitting and receiving signals

The utility model discloses a system for transmitting and receiving signals. Wherein the rotor control part is used for being electrically connected with a steering wheel switch, the stator control part is used for being electrically connected with a tubular column side trip computer, and the rotor control part is in wireless connection with the stator control part so as to achieve information communication between the steering wheel switch and the tubular column side trip computer. The utility model also discloses a clock spring. Information interaction between the steering wheel switch and the tubular column side trip computer of the system for transmitting and receiving the signals is wireless intercommunication, hard wire connection is not needed, and the problems that the size is enlarged and hidden dangers exist in durability and stability of copper foil due to the fact that the functions of a steering wheel in a traditional clock spring are increased and the copper foil is increased are solved. 本实用新型公开
