Connector new overview

December 09, 2019

      Connector, i.e. connector. It is also known as connector, plug and socket in China. Generally refers to electrical connector. The device that connects two active devices to transmit current or signal. Connector is a kind of component that our electronic engineering technicians often contact. Its function is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function. Connector is an indispensable part of electronic equipment. When you observe the current flow path, you will always find one or more connectors. The form and structure of connectors are ever-changing. There are different types of connectors with different application objects, frequency, power, application environment, etc. For example, the connector for lighting on the court and the connector for hard disk drive, as well as the connector for igniting rockets, are quite different. However, 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 only connected with the current. With the rapid development of optoelectronic technology, in the optical fiber system, the carrier of signal transmission is light, glass and plastic instead of the wire in the ordinary circuit. However, connectors are also used in the optical signal path, and their functions are the same as circuit connectors.
1. Benefits:
Improve production process
Connectors simplify the assembly process of electronic products. It also simplifies the mass production process;
Easy maintenance
If an electronic component fails, the failed component can be replaced quickly when the connector is installed;
Easy to upgrade
With the development of technology, when the connector is installed, the component can be renewed, and the new and more perfect component can replace the old one;
Increased design flexibility using connectors allows engineers greater flexibility in designing and integrating new products, as well as in building systems with meta components.
2. Connector performance: the basic performance of connector can be divided into three categories: mechanical performance, electrical performance and environmental performance.
3. "Miniaturization", "high-speed mobility" and intelligence of connector products are the future development trend.
4. Market development:
With the rapid growth of consumer electronics, automotive electronics, communication terminal markets and the continuous transfer of global connector production capacity to Asia and China, Asia has become the place with the most development potential of connector market, and China will become the market with the fastest growth and the largest capacity of global connector market. It is estimated that the growth rate of China's connector market will continue to exceed the global average in the future. In the next five years, the annual growth rate of China's connector market scale will reach 15%. By 2010, China's connector market capacity will reach 25.7 billion yuan.
The main supporting fields of electrical connector are transportation, communication, network, it, medical treatment, home appliances, etc. the rapid development of product technology level and the rapid growth of market in the supporting fields strongly lead the development of connector technology. Up to now, connector has developed into a series and specialized product with complete product types, rich varieties and specifications, diversified structure types, subdivided professional direction, obvious industry characteristics and standard system specifications.
In general, the development of connector technology shows the following characteristics: high speed and digitalization of signal transmission, integration of various types of signal transmission, miniaturization and miniaturization of product volume, low cost of product, table sticking of contact termination, modular combination, convenience of plug and pull, etc. The above technologies represent the development direction of connector technology, but it needs to be noted that the above technologies are not necessary for all connectors, and the requirements for the above technologies are totally different for connectors in different supporting fields and different use environments.
