Background

In a common steering wheel design, 3 or 4 copper rivets are arranged on the lower side of a DAB (driving side main air bag) installation position and are used for contacting with a horn conducting reed of DAB. When touching, the circuit is conducted and the automobile horn sounds. Normally, the rivet is not in contact with the reed, when the DAB is pressed down by an automobile user, the DAB descends, the reed contacts the copper rivet, and at the moment, an automobile circuit system can form a finished circuit loop through a circuit, the DAB reed, a framework and the like, and the circuit drives an automobile horn to sound. However, if the copper rivets on the steering wheel being produced are too low in height or the insulators are present on the rivets, a finished circuit cannot be effectively formed, and the horn cannot sound, which is dangerous for the automobile user and the surrounding personnel.
