Description

technical field [0001] The invention belongs to the field of insertion and extraction force testing, and in particular relates to a testing device for the insertion and extraction force of electrical connector contacts (generally referring to pins and jacks) in high temperature environments. Background technique [0002] As a basic component, the electrical connector's main function is to realize the circuit, signal conduction and control between various components, circuits, equipment, systems, etc. It has a wide range of applications in aviation, aerospace, communication, electromechanical and other industries. The number is considerable and the status is important. With the development of my country's new generation of weapons and delivery technology, especially the development of high-speed and ultra-high-speed cruise missiles and large launch vehicles, it is required that the system can work normally in a complex space environment and electromagnetic environment. The el...

AI Technical Summary

Problems solved by technology

[0005] 1. Measuring the insertion and withdrawal force at room temperature cannot really simulate the actual working conditions of the contacts, and cannot fully consider the influence of high temperature on the insertion and withdrawal force; using the test results at room temperature to replace or infer the insertion and withdrawal force at high temperature cannot reflect the reality Happening

[0006] 2. The existing test methods mostly use manual plugging and unplugging, which cannot accurately control the separation speed and insertion amount, and cannot ensure the precise alignment of the contacts when plugging and unplugging. Human factors have a greater impact on the measurement results of the plugging force

[0007] 3. The insertion and withdrawal force of the electrical connector is not only related to temperature, but also closely related to the number of insertions and extractions (mechanical life). Insert and unplug and check the change of insertion force
