I. Wire connector structure
It is a kind of network connector, which connects the communication cable to the communication port of PLC and can set the terminal resistance at the same time. Connectors are the parts that our electronic engineers often contact. Its function is simple: to build a communication bridge between blocked parts or isolated circuits in the circuit, so as to make the current flow and make the circuit realize the predetermined function. Connector is an indispensable part in electronic equipment. If you look along the current path, you will always find one or more connectors. The forms and structures of connectors are ever-changing. There are various types of connectors according to different application objects, frequencies, power and application environments. For example, the connectors used for lighting on the court are very different from those used for hard disk drives and rocket ignition. But no matter what kind of connector, it is necessary to ensure the smooth, continuous and reliable flow of current.
Generally speaking, the connection of connectors is not limited to current. Today, with the rapid development of photoelectric technology, the carrier of signal transmission in optical fiber system is light, and glass and plastic replace the wires in ordinary circuits. However, connectors are also used for optical signal paths and have the same function as circuit connectors.
Second, the brand of wire connector
1.Tyco- 1998 acquired AMP and became the leader in connector industry. Products are widely distributed in the industry, and are very strong in automobiles, computers, peripherals and industries. Delivery/quality can't be generalized, but it is ok on the whole.
2.Molex- started with terminals and molded cases, so now terminal molded cases are the most popular in Chinese mainland, and it is the world leader in consumer electronic connectors, but for most 5XXXX (Nissan),? 9XXXX (made in Europe), 7XXXX (made in America) and 4XXXX (made in America) series materials, the delivery time is terrible. Of course, the quality is ok.
3. Amphenol has become the third largest connector in the world through acquisition and merger, and is very famous in the fields of military industry, aerospace/aviation and communication. In 2005, it acquired Tereda, which increased its competitiveness in the high-speed communication connector market. But it doesn't have a unified website, different products, different branches and different websites like TYCO and MOLEX. * * * There are dozens of websites belonging to Ann Fanor.
4.FCI connector, also known as Famatong, was acquired by American consortium last year, and it has strong strength in communication connector and automobile connector.
5. SAMTAC-the most famous is board-to-board products (row needles, bus bars, etc. Different people have different views on delivery time and price.
6.JAE daily avionics mainly deals in computer peripherals, automobile connectors and communication connectors, but it is more famous in Chinese mainland, FPC and other precision connectors.
7. Phoenix-Germany, which is famous for its industrial connectors and terminal boards, is expensive.
8.3m-American company, in optical fiber heat? In terms of melt, there is a strong patented technology, and MBR connectors are also good.
The above example first introduces the structure of wire connector, from which we can know that it belongs to network connector. With the different parameters such as application object, frequency and power, the available forms and structures are ever-changing. Therefore, consumers should not be limited to one of them, but should refer to their own situation, including the demand budget, and start to comprehensively screen out the best solution. Then, regarding the choice, the nine brands recommended above are considered as suggestions from Bian Xiao.
