Abstract

The invention relates to the field of pressure testing, and especially relates to an IC card connector elasticity testing method and terminal, and a testing card and a testing machine. The IC card connector elasticity testing method comprises carrying pressure testing on a strain gauge on the testing card, recording and saving different strain values corresponding to different pressure values applied to the strain gauge, and obtaining a plurality of coordinate points; obtaining an expression between the pressure value and the strain value according to the plurality of coordinate points; obtaining the strain value of the strain gauge when the testing card is placed in the IC card connector; and obtaining the elasticity of the contact of the IC card connector according to the expression andthe strain value. According to the invention, the elasticity value of the contact in the IC card connector can be tested, and therefore whether the IC card connector meets the demand of an EMV standard on the elasticity of the contact of the IC card connector is effectively estimated, during the testing process, the IC card connector is not damaged, once a model between the strain gauge and the pressure is established, the elasticity of metal contacts in a batch of IC card connectors can be tested, the testing efficiency is improved, and the usage cost is reduced.

Description

technical field [0001] The invention relates to the field of pressure testing, in particular to a method for testing the elastic force of an IC card holder, a terminal, a test card and a test machine. Background technique [0002] At present, there is no general test method for the elastic force of the metal contacts in the IC card holder. Usually, the elastic force of the contacts is determined by the design method and material of the metal shrapnel of the contacts. Due to structural tolerances or metal fatigue, etc., IC card holder contacts may have reduced elastic force or uneven pressure force. A general device and test method are needed to test the pressure of IC card holder contacts. Contents of the invention [0003] The technical problem to be solved by the present invention is: the present invention provides a method for testing the elastic force of an IC card holder, a terminal, a test card and a testing machine, which solves the problem that the contact pressure...
