Contact pressure is an important indicator of the joint and directly affects the contact resistance and wear of the contact pair. In most constructions, it is difficult to measure contact pressure directly. Therefore, contact pressure is usually measured indirectly by the separation force of one leg. Firstly, as far as the mechanical properties of military electrical connectors are concerned, this is actually quite easy to grasp.
The insertion force of a military connector should be high in order to ensure contact stability. With little external interference, which does not affect normal operation, the strength is the exact opposite and naturally convenient. If possible, dial once and insert once after installation to see if the connector is tight and how well the connection performs. This is an important constant criterion for measuring the performance of electronic equipment source components. The electrical performance of the connector mainly includes contact resistance, insulation resistance and electrical strength. Contact resistance is the main working indicator, determined by the specification. Insulation resistance mainly refers to its external reliability performance, i.e. insulation performance. As the electrical performance is an indispensable function among its main functions, it is more critical and plays an important role in determining the reliability of use, so it should attract our attention. Sometimes we can refer to manuals and institutional accreditations so that we can understand them well.
When selecting connectors and military electrical connectors, this is an important factor in ensuring reliable use. In addition, the environmental performance of the connector. Currently, electronic equipment is widely used in a variety of environments, and therefore must be able to adapt to a variety of environmental connectors. But how to ensure that the environmental adaptability of the connector, especially targeted connectors, depending on the actual situation, which are commonly resistant to temperature, humidity, salt and corrosion. Those with functional connectors can only be tested by specialised agencies. Connectors that are not adapted to the environment can cause hidden problems if they are not used in harsh environments. Connectors are very important in aerospace, railway and road transport applications. It is an important indicator for testing the mechanical construction and electrical contact reliability of electrical connectors. Relevant test methods are specified. The shock test shall specify peak acceleration, duration, pulse waveform and electrical continuity interruption time. Other environmental properties Depending on the requirements of use, other environmental properties of electrical connectors are gas tightness (air leakage, liquid pressure), liquid immersion (resistance to certain liquids), low air pressure, etc.
