The development trend of high-performance connector terminals

High-speed transmission means that modern computers, information technology and network technology require that the time-scale rate of signal transmission reaches the megahertz frequency band, and the pulse time reaches sub-milliseconds, so high-speed transmission electronic connector terminals are required. The high frequency is to adapt to the development of millimeter wave technology, and the terminals of radio frequency coaxial electronic connectors have entered the millimeter wave working frequency band. Large current is also an important development direction for many electronic connector terminals. Although short, small, lightweight, energy-saving and low-consumption are the direction of consumer electronics products, the following two aspects determine the evolution of power supply in the direction of large current in many applications. Let's take a common computer CPU as an example to illustrate the reasons: 1. The improvement of computer performance requires an increase in CPU computing speed and an increase in the number of transistors required. Therefore, power consumption rises. Under the condition of the same voltage, the current rises in the same proportion. Gradually reducing is conducive to reducing power consumption, but its physical characteristics determine that the reduction ratio of power consumption is less than the voltage. Therefore, the increase in current is also an important indicator for testing the high-performance development of electronic connector terminals. In the connector terminal design, each signal transmission terminal is separated from each other. Differential signal pairs can achieve this goal well, because each differential signal pair has a ground pin on one side to reduce crosstalk. Usually the first layer is an area with open pins to separate adjacent ground terminals. The next level is the ground shield installed between the rows. The top application will include a metal ground structure surrounding each signal terminal. Such a metal shield achieves the best combination of data transmission speed and signal integrity. Reliability for use in extreme environments and environmental protection. In the modern high-tech industry, there are many connectors that are used under extreme environmental conditions. Under ultra-high temperature, low temperature, vibration, hot and humid environment, and corrosive environment, electronic connectors can be used effectively and normally, which makes the raw materials in the connector There are higher requirements in terms of selection, structural design, and processing technology. New high temperature resistant materials, new electroplating coating process, and more flexible alloy materials make future connector terminals more adaptable to harsh environments.
