It is estimated that in the future, the growth rate of China's connector market will continue to exceed the global average level. In the next five years, the average annual growth rate of China's connector market will reach 15%. By 2010, China's connector market capacity will reach 25.7 billion yuan. With the rapid growth of consumer electronics, automotive electronics, communication terminal market and the continuous transfer of global connector production capacity to Asia and China, Asia has become the most potential market for connector market, and will become the fastest growing and largest market for global connector.
Generally speaking, the development of connector technology presents the following characteristics: high speed and digitization of signal transmission, integration of all kinds of signal transmission, miniaturization and miniaturization of product volume, low cost of product, surface pasting of contact termination mode, modular combination, convenience of plug and pull, etc. The above technologies represent the development direction of connector technology, but it should be noted that the above technologies are not necessary for all connectors, and the requirements for the above technologies are completely different for connectors in different supporting fields and environments.
The main supporting fields of line to board connector are transportation, communication, network, it, medical treatment, home appliances, etc. the rapid development of product technology and the rapid growth of market in the supporting field strongly promote the development of connector technology. So far, connector has developed into a complete range of products, rich varieties and specifications, diverse structural types, subdivision of professional direction, obvious industry characteristics, serialization and specialization of standard system and specification.
Development direction of wire to board connector:
The development of connector should be miniaturization (because many products face smaller and lighter development, there are certain requirements for spacing and appearance size, height, which will make the product more precise, such as the best choice of line to board, small spacing of 0.6 mm and 0.8 mm), high density, high speed transmission and high frequency. The total number of effective contacts of high density PCB (printed circuit board) connectors is 600 cores, and the maximum number of special devices is 5000 cores.
Miniaturization means that the center distance of the connector is smaller, and the high density is to realize the large number of cores. High speed transmission refers to the requirement of modern computer, information technology and network technology that the time scale rate of signal transmission should reach the megahertz band and the pulse time should reach sub millisecond. Therefore, high speed transmission connector is required. In order to adapt to the development of millimeter wave technology, RF coaxial connectors have entered the millimeter wave frequency band.
