THE ROLE OF CONNECTORS IN COMMUNICATION SYSTEMS

THE ROLE OF CONNECTORS IN COMMUNICATION SYSTEMS


A connector is a component that our electrical engineering technicians often contact. Its function is very simple: to establish a communication bridge between the blocked or isolated circuits in the circuit, so that the current flows and the circuit achieves the intended function. Connectors are an indispensable part of electronic equipment. If you observe the path of current flow, you will always find one or more connectors. The form and structure of connectors are ever-changing. With different application objects, frequencies, powers, and application environments, there are various forms of connectors. But no matter what kind of connector, it is necessary to ensure that the current flows smoothly, continuously and reliably. Generally speaking, the connector is not limited to the current. In today's rapid development of optoelectronic technology, the carrier of signal transmission in optical fiber systems is light. Glass and plastic replace the wires in ordinary circuits, but optical signals connectors are also used in the pathway, and they serve the same purpose as circuit connectors.


Any network needs connectivity in order to combine a single device into a network system. In today's networks, interconnected devices, or connectors, play an important role: firstly, it can electrically connect individual devices to form a larger network system. On the other hand, standardized interconnections are now used to enable equipment made by different companies to work together to build a network in a block to meet the needs of businesses or communities.


Therefore, in the wired communication system, the role of the connector mainly has three aspects. First, electrical connections can be made to circuit boards and individual electrical components within a single device. Second, if standardized interconnections are used, devices made by different companies can be connected and work together to build a network in a block to meet the needs of businesses or communities. Third, it is designed to achieve reliable functions to withstand the known working environment and the intensity of work during the equipment's eye service period.


According to the requirements of the wired communication system for the connector, the following aspects should be considered when designing:


1. Gold-plated contact interface for higher wear resistance and good electrical characteristics.


2. Redundant contact interface to ensure high reliability.


3.  It can choose air tight connection or PCB welding.


4. The external features of the shell should be easy to guide and guide when inserted.


5. Use different pin heights to ensure the order of signal and ground connection.


6. High-power power supplies should use special terminals, which should be different from the signal contact terminals.


7. Ensure EMI characteristics and chassis grounding.


In addition, the application of connectors in wireless communication systems is more complicated. The internal interconnection of base stations in typical wireless communication systems requires a variety of electronic connectors. Such as RF connectors, power connectors, backplane connectors, input / output connectors and printed circuit board connectors. The types of power connectors used in wireless communication systems include integrated backplane power systems, daughter board / stacking connectors, signal bus-to-board connectors, board-to-board power connectors, and power to Cable / cable Nrn. Swap board connector, power connector for microprocessor and connector for power input. Whether the connector is in a wired communication system or a wireless communication system, ensuring the integrity of signal transmission is its primary mission. Therefore, the connector needs to consider:


1. Continuity of impedance with the entire interconnected transmission line.


2. Crosstalk between the pins of the connector.


3. There are timing requirements, and the delay on the connector must be considered.


With the rise of mobile communication equipment and the improvement of the national communication network, the application of connectors in communication systems is becoming more widespread. On the other hand, the connector performance requirements have been gradually improved. The widespread use of high-performance and high-reliability communication connectors may become the driving force of the communication industry.
