Why should connectors be tested for insertion and extraction force?

I. Why should connectors be tested for insertion and extraction force? The use of standard test male test individual terminal insertion and withdrawal of the force required to assess the quality of the terminal characteristics, to confirm that the connector connector in the use of the process of generating the force is sufficient to maintain the function of the connector and suitable for the consumer's hand. Test Methods: 1, the test connector PIN pin or BLADE its size and surface roughness are in line with the provisions of the MIL-3197. 2, the test connector PIN pin or BLADE should be cleaned regularly to avoid the surface coating and affect the accuracy of the measurement data. 3, test step 1 (using the connector PIN pin or BLADE): A, the first insertion and removal to adjust the status of the terminals. B. Insert a larger size of the test connector PIN pin or BLADE, at the same time measuring the insertion force to pull out the connector PIN pin or BLADE, and replace the smallest size of the test test points: 1. test like the entire connector connector, full ass'y. 2. test the role of the axis for the connector normal use of the direction of the connector. 3. unless otherwise specified, test speed Unless otherwise specified, the test speed is defined as 25.4mm/minute.
