GRADUAL INCREASE OF STIFFNESS FOR ELECTRIC CONNECTION STRUCTURE IN TIRE

摘要

PROBLEM TO BE SOLVED: To provide a distortion-endurable electric connection structure and its forming method.

SOLUTION: A conductive lead such as wire is connected with an electric circuit in such a form as to generate a connection assuring excellent endurance against a mechanical stress caused by a motion of the lead relative to the electric circuit, a rotation, etc. A material to produce a region as decreasing the deflecting compliance or heightening the stiffness in the area near the connection point is formed around the lead and near the connection point to the electric circuit. According to one embodiment, the lead may assume a coil form or a shape capable of heightening still more the endurance against the mechanical stress. In another example of embodiment, it is also considerable of installing additionally an element which assists controlling the stiffness of the area around the connection point.
