What are the future technology trends of circular aerospace connectors?

I. What is the future technology development trend of circular aviation connectors? Circular aviation plugs because of its better performance and higher cost-effective now very popular one of the connectors, do you know the future development trend of circular aviation plugs?1. Narrow pitch contact pitch is reduced, which can exponentially increase the number of contacts per unit area. Therefore, the pitch is Henderson aviation plug http://www.hkct888.com高密度小型化的重要指标之一. The realization of high-density, narrow pitch relies on the precision manufacturing of micro-contacts. A major breakthrough in the miniaturization of pinhole contacts is the change in the structure of the traditional pin socket by retracting the elastic pin into the insulator so that the socket becomes tubular and passes out of the insulator. This structure protects R's relatively fragile pins and solves alignment problems during insertion. Contact of the pinhole with this structure can increase the density by a factor of three to four. Currently, there are at least five types of elastic pins that have been used in miniature D-type connectors and circular connectors.2. Thinning Modern electronic equipment places new demands on connectors to reduce height and achieve thinness. The distance between connectors is rapidly decreasing, but not easy to reduce the height. The connector has been one of the higher components on the PCB, the height (Z-direction) can be reduced to greatly reduce its size. Therefore, thinning is an important aspect of connector miniaturization development. Currently, pinhole contact jacks use a cantilever beam structure. In order to maintain sufficient positive pressure, not exceeding the yield point of the material due to deformation, its elastic arm should have a corresponding length to ensure reliable contact. At present, the height of the thin connector can generally reach below 10mm, lower has reached 1.5mm, is Molex developed 0.5mm pitch connector products. With the development of science and technology, especially through the development of better performance of the elastic material, the connector of the thin and low height will be further developed.3. Low insertion force connector miniaturization and multi-core closely linked. In order to solve the problem of excessive insertion force of aviation plugs, aviation plugs are increasingly using ZIF (zero insertion force) and LIF (low insertion force) structure. Without these structures, it is difficult to insert and remove connectors.
