How to select industrial connectors?

What is an industrial connector? Industrial connectors are specifically designed to build a rugged Ethernet connection in harsh environments, which is tougher, stronger, and more resilient than previous connectors. Electronic engineers and technicians often come into contact with industrial connectors. Its function is very simple. It builds a communication bridge between disconnected and isolated circuits in the circuit, and passes in current to enable the circuit to achieve a given function. Industrial connectors are indispensable components in electronic equipment. One or more connectors can be found when observed through the channel through which current flows. Moreover, its form and structure are ever-changing, and there are various forms of connectors according to different application objects, frequencies, power, application environments, etc. Under general environmental conditions, industrial connectors can be stored for more than 8 years! Generally speaking, aviation plugs in industrial connectors connect more than just current. Aviation plug is not only a simple auxiliary interface component in aerospace system engineering, but its reliability directly affects the success of aerospace system engineering. In addition to the advanced design technology level, the important factors affecting its technical performance and service performance must also pay full attention to the selection of materials.

So what requirements must an aviation plug option meet? The material chosen in the first place has the advantage of being lightweight. Because weight is of great significance to improve the technical performance index and economic benefit of the space shuttle. Because of its light weight and good corrosion resistance, aviation plugs used in aerospace engineering are mostly made of magnesium-aluminum alloy at present. Aviation plugs are mainly used in aerospace environments and are susceptible to the impact of temperature and radiation. Therefore, the selected materials must be resistant to high temperatures and radiation. Generally, PVC plastic cannot be used. In addition, considering the safety of the space shuttle, the connectors used should have the advantages of non-toxic and flame retardant. You can also choose materials that can quickly extinguish the fire by themselves when burned. The shell material must ensure that the strength, forming technology and stiffness of the designed structure meet the requirements of aerospace system. For example, hard aluminum must be selected for machining boxes. Duralumin is because of its good machinability; The cast aluminum selected for die-casting box must have good fluidity and compactness; The cold extrusion box body is made of cast aluminum with good cold deformation plasticity; In the case of glass sintered sealed connectors, since the expansion coefficients of these materials coincide with the expansion coefficients of glass, the housing and the contacts are made of a low expansion alloy; Some elastic parts such as claws, springs, short-circuit rings, and snap rings mainly play the functions of positioning, locking and shielding, so industrial connectors should choose materials with reliable elastic functions.
