Description

Technical Field

[0002] The plugging and pulling force tester is suitable for various low-temperature test environments required for products such as wires and cables and electrical accessories. Its main function is to test the force characteristics of plug-in and plug-out parts during the plug-in and pull-out process, so as to evaluate whether the plug-in and pull-out performance of the product meets the relevant standards. With the rapid development of the electronics industry, the scope of use of connectors and plug-in parts continues to expand, and the market has put forward higher requirements on their quality and performance. However, the current plug-in and pull-out force test equipment still has the following shortcomings in practical applications.

[0003] In traditional insertion and extraction force testers, the equipment usually lacks effective reset and limit protection functions.
