Resistant Environment For The Rapid Separation Of Small Circular Electric Connector Efficient Shell Shield

Electromagnetic screen is a popular method for controlling electromagnetic interference. Electronic components must have the characteristic of high electromagnetic interference ability, in order to fulfill the requirements of modern electronic system with high precision and dependability. Electric connectors is one of the best popular electronic components, and its screen ability makes great importance on the transmission of signal, so solving electromagnetic screen problem is the first thing for designing electric connectorsThe background and application value is described in the paper. The design theory of electromagnetic screen and design method are also presented. The design method of connectors,electrical,circular,miniature,high density,quick disconnect,environment resistant,general specification is confirmed in combination with the project. The process of reasoning and the result is further demonstrated according to academic designation and practicality, and all the process are introducedThe electric connectors hold the advantage of room-small,light weight, quick connecting and disconnecting,resistting vibration and strike, which limits the method of screen designation. The electromagnetic screen is realized via special design on the shell in the project. The screen ring is designed for confirming high dependable electromagnetic screen, as the shells are separated. The size is confirmed through academic calculation, and high dependable electromagnetic screen is achieved. The screen ring ensures the exterior and mechanical function of connector, without additional components. The simple structure confirms the advanced technology in comparing with the same series products.I am the design director of project, in charge of the prophase reasoning, structure designation, and validation. The project, of Connectors of electrical,circular,miniature,high density,quick disconnect,environment resistan gets across all the testing and checkup through two years design reasoning, structure research and practicality improvement. The project is successfully used on many keystone m odel, and requirements and purposes are reached.
