Future Technology Development Trend Of Circular Aviation Plug

Circular aviation plug is one of the most popular connectors because of its better performance and higher cost performance. Do you know the future development trend of circular aviation plug? Let us introduce Chengyang Electric to you, let's take a look and understand.

narrow pitch

Contact pitch is reduced, which can multiply the number of contacts per unit area. Therefore, the spacing is one of the important indicators for the high-density miniaturization of Henderson aviation plugs. The realization of high density, narrow pitch relies on the precise fabrication of microcontacts. A major breakthrough in the miniaturization of pinhole contacts is to change the traditional pin-socket structure, shrinking the elastic needle into the insulator, making the socket into a tubular shape and passing through the insulator. This structure protects the relatively fragile pins of R and solves the alignment problem during insertion. Contact of pinholes with this structure can increase the density by a factor of three to four. At present, there are at least five types of spring pins, which have been used in miniature D-type connectors and circular connectors.

Thinning

Modern electronic equipment puts forward new requirements for connectors, that is, to reduce height and achieve thinning. The distance between the connectors decreases rapidly, but it is not easy to reduce the height. The connector has always been one of the tallest components on a PCB, and the reduction in height (Z direction) can greatly reduce its size. Therefore, thinning is an important aspect of connector miniaturization development. At present, the pinhole contact jack adopts a cantilever beam structure. In order to maintain a sufficient positive pressure and not exceed 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 thin connectors can generally reach 10mm or less, and the minimum has reached 1.5mm. It is a 0.5mm pitch connector product developed by Molex. With the development of science and technology, especially through the development of elastic materials with better performance, the thinning and low height of connectors will be further developed.

low insertion force

Connector miniaturization and multi-core are closely linked. In order to solve the problem of excessive insertion force of aviation plugs, aviation plugs increasingly adopt ZIF (zero insertion force) and LIF (low insertion force) structures. Without these structures, it would be difficult to plug and unplug the connector.
