Future Development Trends of Electronic Connector Technology
Connectors, as key components for current or signal connections, are also an important component of industrial systems. With the rapid development of personal mobile terminals, home smart appliances, information and communication industry, transportation new energy industry, aerospace technology, artificial intelligence, medical electronic devices and other fields, higher requirements have been put forward for connectors in terms of functionality, appearance, performance, and usage environment.
 
1. The development trend of miniaturization and integration
In order to meet the requirements of portable, digital, and multifunctional electronic devices, as well as automated production and assembly, electronic connectors must undergo product structure adjustments. The products are mainly developing towards small size, low height, narrow hearing distance, multifunctionality, long lifespan, surface installation, and other directions.
Miniaturization refers to the smaller center to center spacing of electronic connectors, while high density enables the digitization of large cores. The miniaturization of consumer electronic products requires components to be miniaturized, thin, and high-performance, which also promotes the development of connector products towards miniaturization and small spacing. The miniaturization of electronic components requires higher technological requirements. All of this requires a strong industrial mold foundation to effectively support.
 
2. The trend of intelligent development
Nowadays, it is a world of rapid development of information, and people's requirements for any type of information or technology are becoming increasingly high. With the rapid development of information and communication data, wireless interconnection has come to every one of us. The application of technologies such as smartphones, smart wearables, drones, unmanned driving, VR reality, and intelligent robots, as well as the intelligent development of electronic connectors with IC chips and control circuits, is an inevitable trend. This will enable electronic connectors to more intelligently grasp the usage status of electronic devices and improve their own performance to achieve intelligent wireless bridging.
3. The trend of high-performance development
High speed transmission refers to the requirement of modern computer, information technology, and networking technology for signal transmission with a time scale rate of megahertz frequency band and a pulse time of sub milliseconds. Therefore, high-speed transmission electronic connectors (connectors) are required.
High frequency conversion is to adapt to the development of millimeter wave technology, and RF coaxial electronic connectors have entered the millimeter wave operating frequency band.
High current is also an important development direction for many electronic connectors. Although small, lightweight, energy-saving, and low consumption are the efforts of consumer electronics products, the following two aspects determine the evolution of power supply towards high current in a considerable number of application scenarios. We take the common computer CPU as an example to illustrate the reasons: firstly, the improvement of computer performance requires an increase in CPU computing speed and the number of required transistors, resulting in an increase in power consumption. Under the condition of constant voltage, the current increases proportionally; Secondly, with the advancement of semiconductor technology, the operating voltage of transistors gradually decreases, which is beneficial for reducing power consumption. However, their physical characteristics determine that the reduction ratio of power consumption is not as high as that of voltage. Therefore, increasing current is also an important indicator for testing the high-performance development of electronic connectors.
Anti signal interference and shielding, as the data transmission speed increases, the effects of capacitance and impedance become more pronounced. The signal on one terminal can interfere with adjacent terminals and affect their signal integrity. In addition, the grounding capacitance reduces the impedance of high-speed signals, causing signal attenuation. In the new connector design, each signal transmission terminal is separated from each other. Differential signal pairs can effectively achieve this goal, as each differential signal pair has a ground pin on one side to reduce crosstalk. Usually, the first layer is the area where the matrix legs are opened to separate adjacent ground terminals. The next level is the grounding shield installed between rows. The top-level application will include a metal grounding structure surrounding each signal terminal. This metal shielding achieves the best combination of data transmission speed and signal integrity.
Reliability and environmental friendliness in extreme environments. In the modern high-tech industry, there are many connectors that are used under extreme environmental conditions, such as ultra-high temperature, low temperature, vibration, humid and hot environment, and corrosive environment. Electronic connectors can be effectively and normally used, which makes higher requirements for the selection of raw materials, structural design, and processing technology of connectors. New high-temperature resistant materials, new electroplating coating processes, and more elastic alloy materials make future connectors more adaptable to harsh environments.
 
 
4. Beautiful and fashionable appearance, more emphasis on user-friendly development trend
With the continuous development and progress of multimedia and other technologies, connectors are also undergoing continuous changes in adaptability to their main body. With the increasing development of science and technology, a good connector not only needs to have a more beautiful and fashionable appearance, but also a more durable material, and more convenient operation. More importantly, the connection design of its core parts needs to be more refined and precise. This way, there will be no situation where the card slot of a typical data connector becomes loose after prolonged use, and in severe cases, the data transmission part of the connector will completely collapse, which will greatly damage customers' confidence in purchasing the main product.
