Safe use of connectors and connection range of aviation plugs

First of all, the mechanical properties of the connector are actually relatively easy to master. We can demonstrate it ourselves, especially the dial-in force performance. We can know its effect through actual operation. The dial-in force must be greater, so as to ensure the stability of its contact, but the opposite will not affect the normal work force under the condition of small external force interference. Naturally, the easier and more convenient it is, the better. If possible, dial-in once to see if the joint degree is tight after installation.

The electrical performance of the connector mainly includes contact resistance, insulation resistance and power intensity, among which contact resistance is its main working index, which can be determined by reading the manual, while insulation resistance mainly refers to its external safety performance, that is, its insulation performance. Because electronic performance is the must of its main functionality, it is particularly critical, and it also plays a very important role in determining the safety of use, so it must be attached great importance to it. Sometimes you can refer to the manual and the certificate of authoritative organizations, so you can know fairly well. Ensuring safe use and safe use is the top priority when choosing connectors and connectors. Let's talk about the environmental performance of connectors. Nowadays, electronic equipment has many applications in various environments, so connectors that can adapt to various environments are also very needed. However, how to ensure the selection of connectors with strong environmental adaptability and special pertinence must be based on the actual situation. Among them, the more common ones are temperature resistance, humidity resistance, salt resistance, corrosion resistance, etc. These connectors with special functions need to be tested by state specialized agencies before they can be passed. Aviation plug is particularly important in special application environments such as aviation and aerospace, railway and road transportation. It is an important index to test the robustness of mechanical structure and electrical contact reliability of electrical connectors. There are clear provisions in the relevant test methods. The peak acceleration, duration and shock pulse waveform shall be specified in the impact test, as well as the time of interruption of electrical continuity. Other environmental properties Depending on the use requirements, other environmental properties of the electrical connector include tightness (air leakage, liquid pressure), liquid impregnation (resistance to vice-habituation of specific liquids), low air pressure, etc.
