Abstract
An apparatus for measuring a permanent displacement of an elastic contact segment of a terminal having a displacing load imposing unit, wherein a terminal to be measured is clamped on a surface of a terminal mounting plate, a load imposing head is operated to impose load onto the elastic contact segment of the terminal with its load imposer, a displacement of the load imposing head is measured by a measuring instrument and the contact between the load imposer an the elastic contact segment of the terminal is detected by a circuit tester. An initial contact position of the load imposer with the elastic contact segment is measured at first and continuing to load the elastic contact segment until it reaches a predetermined deformed position. This deformed elastic contact segment is inprocess heat treated and then unloaded by reversing the movement of the load imposer after completing the heat treatment. A leaving position of the load imposer from the elastic contact segment is measured, and then a permanent deformation of the elastic contact segment is measured by a difference between the displacement from the predetermined deformed position to the leaving position and the displacement from the initial contact position to the predetermined deformed position.
