Role connector in communication system
Any network requires connectivity to the combination of individual devices into a network system. Today the network, i.e. interconnection device connector play an important role: first, a single device which can be electrically connected to form a larger network system; on the other hand, are now standardized interconnection, the equipment manufactured by different companies can be mutually work together, resulting in a block to construct a network to meet the needs of commercial or community.
Thus, in the wired communications system, a connector role mainly in three aspects: First, to the board and a single electrical component within a single device to ask electrically connected; and second, if the use of standardized interconnection, can make different companies Equipment connected to each other to work together, resulting in a block to construct a network to meet the needs of commercial or community; and third, to achieve reliable by design features to withstand the known working environment and equipment eye service period The work intensity.
For wired communications system connector requirements, the design should consider the following aspects:
1. The gold-plated contact interface, used to ensure higher wear resistance and good electrical properties;
2. The redundant contact interface, Paul Wang high reliability;
3. You can select the connection airtight or PCB soldering;
4. To facilitate the external characteristics of the housing and the guide insert Daozheng;
5. Use a different pin height to ensure the signal and ground connection order successively;
Contact terminal 6. The power supply to use special terminals, and the signal to be different;
7. To ensure EMI characteristics and chassis ground.
