ONE. What are the plating methods for military aviation plugs? Military aviation plugs are electromechanical components connected to electrical circuits, the correct selection and use of aviation plugs is an important aspect to ensure the reliability of circuit operation. Today, we mainly talk about the plating method of aviation plug, first of all, we need to understand a few parameters: insulation resistance it refers to the voltage applied to the insulating part of the aviation plug, so as to make the insulating part of the leakage current within or on the surface of the surface and the resistance value presented. Mechanical parameters it is directly affect the size of the contact resistance and the amount of wear on the contact pair. Military aviation plugs generally consist of a plug and a socket, where the plug is also known as a free end plug and the socket is also known as a fixed aviation plug. The connection and disconnection of circuits is realized through plugs, sockets and insertion and separation, thus giving rise to the various connection methods of plugs and sockets. The specific use is decided according to the working environment. Aviation plug ordinary type to thiosulfate as the main complexing agent, the type of sulfur-free organic matter as the main complexing agent. Using Na3 [Au (SO3) 2] gold layer thickness of up to 1.5μm, available in high-density flexible circuit boards and electronic ceramics on the gold plating. Military aviation plug is mainly used for circuit board through-hole plating and non-conductor surface metallization. The leather to remove toxic formaldehyde replaced by cheap non-toxic hypophosphite, there are no commercialized products at home and abroad, has basically completed laboratory research. But the connection speed is slow and not suitable for the need for frequent insertion and removal and rapid connection of the occasion. Bayonet connection due to its three bayonet groove guide longer, so the connection speed is faster, but it is more complex manufacturing, the cost is also higher. It can be seen that the aviation plug that there are disadvantages and advantages, the overall advantage is still very large.
