An electronic connector is a device that transmits electronic signals (analog or digital) and provides a separate interface for connecting two sub-electronic systems. It is a component used to complete an electrical connection between a circuit or an electronic machine.Such as: power plug/socket, IC pin, telephone plug, etc.Widely used in electronics industry.

Trends analysis for electronics technology future

1、Micro - miniaturization and integration trends

In order to meet the requirements of portable, digital and multifunctional electronic machine, as well as the automation of production and assembly, the product structure of electronic connectors must be adjusted.Products mainly to small size, low height, narrow smell distance, multi-function, long life, surface installation and other directions.

Miniaturization refers to the electronic connector (connector) center spacing is smaller, high density is to achieve large core number.The miniaturization of consumer electronics products requires a combination of miniaturization, thinness and high performance components, which also promotes the development of miniaturization and small spacing connectors.The miniaturization of components requires more technology.This requires a strong industrial tooling base to support it effectively.

Today is a world of rapid development of information, no matter what kind of information or technology, people's requirements are getting higher and higher.From the rapid development of information and communication data, wireless interconnection has come to every one of us, from the application of smart phones, smart wearers, drones, unmanned vehicles, VR reality, intelligent robots and other technologies, the development of intelligent electronic connectors equipped with IC chips and control circuits is an inevitable trend.This will enable the electronic connector to be more intelligent to understand the use of electronic devices, and improve the performance of the connector itself to achieve smart wireless bridge.

3、High-performance development trend

High speed transmission refers to the modern computer, information technology and networking technology requires the signal transmission time scale rate of megahertz frequency band, pulse time of sub-millisecond, so high speed transmission electronic connector (connector) is required.

In order to adapt to the development of millimeter wave technology, rf coaxial electronic connectors (connectors) have entered the millimeter wave operating band.

High current is also an important development direction for many electronic connectors (connectors).Although short and light, energy saving and low consumption is the direction of consumer electronic products, but the following two aspects determine in a considerable number of applications, power supply to the direction of the evolution of large current, we take the common computer CPU as an example to explain the reason:First, the improvement of computer performance, CPU computing speed, the number of transistors required to increase, power consumption is therefore increased, in the case of constant voltage, current proportional increase;Second, with the progress of semiconductor technology, the working voltage of the transistor is gradually reduced, which is conducive to the reduction of power consumption, but its physical characteristics determine that the reduction ratio of power consumption is less than the voltage. Therefore, the increase of current is also an important index to test the development of high performance of electronic connectors.

Signal interference and shielding, as data transmission speed increases, capacitance and impedance also become more obvious.Signals from one terminal can cross stalk adjacent terminals and affect their signal integrity.In addition, the grounding capacitance reduces the impedance of the high-speed signal, so that the signal attenuation.In the new connector design, each signal transmission terminal is separated from each other.Differential signal pairs work well for this purpose because each pair has ground pins on one side to reduce crosstalk.Usually the first layer is an open pin area to separate adjacent ground terminals.The next level is an interline grounding shield.A top-level application would include a metal grounding structure surrounding each signal terminal.This metal shield achieves the best combination of data transmission speed and signal integrity.

Resistance to extreme environment reliability and green environmental protection.In the modern high-tech industry, there are many connectors involved in the use of extreme environmental conditions, ultra-high temperature, low temperature, vibration, humid heat environment, corrosive environment, electronic connectors can be used effectively and normally, which makes the connector in the selection of raw materials, structural design, processing technology has higher requirements.New high-temperature resistant materials, new electroplated coating process, and more resilient alloys make future connectors more adaptable to harsh environments.

4、Appearance beautiful fashion more attention to the use of human development trend

With the continuous development and progress of multimedia and other technologies, connectors are also changing to adapt to their main body.Connector with the increasing development of science and technology, a good connector not only to the appearance of more and more beautiful fashion, material to more and more durable leather, more and more convenient operation, more important is the core part of the connection design to more and more refined and precision.In this way, the data transmission part of the connector will be completely paralyzed when the card slot becomes loose after a long time, which will greatly hurt customers' confidence in the purchase of the main product.

Nowadays, the speed of electronic products and equipment upgrading is very fast, which makes the connector industry in the future development trend to miniaturization, integration, intelligence, high performance and human use are the future development trend. Only in this way can we comply with the development of The Times, or it will be eliminated by the market sooner or later.
