PURPOSE:To obtain an easy and exact connection by forming a fitting part of a clip type lead pin by using a shape memory alloy. CONSTITUTION:A lead terminal 13 formed on a liquid crystal panel substrate, and a fitting part of a clip type lead pin which is connected by fitting the lead terminal 13 are formed by using a shape memory alloy. As for a fitting part 14 of a clip type lead pin 11 using such a shape memory alloy, a gap 15 is formed a little smaller than a thickness of a substrate 12, the gap 15 is spread out in a state that the fitting part 14 causes a martensite deformation, usually so that it becomes wider enough than a thickness of the substrate 12, and the plastic deformation is made in advance. In this state, the substrate 12 is inserted into the fitting part 14, and the positioning is executed. Subsequently, a temperature of the fitting part 14 is raised to about 50 deg.C and it is returned to the previous shape of the plastic deformation, by which the fitting part 14 clamps firmly the substrate 12, and the clip type lead pin 11 and the liquid crystal panel are formed as one body. In this way, the clip type lead pin is attached easily, and the same exact fixation as a shrink fitting is obtained after its installation. |
