Electronic connector (also often called a circuit connector, electrical connector), a conductor device that bridges two conductors on a circuit so that current or signals can flow from one conductor to another.
An electronic connector is an electrical system that can provide separate interfaces for connecting two secondary electronic systems. Simply put, components used to complete electrical connections between circuits or electronic machines become connectors. That is the bridge between the two.
Electronic connector is a device that transmits electronic signals (analog signals or digital signals) . It can provide separate interfaces to connect two secondary electronic systems. It is a component used to complete the electrical connection between circuits or electronic machines.
Such as: power plug/socket, IC socket, telephone line plug number. Widely used in electronic industry.
1Future development trend
1Development trend of microminiaturization and integrationIn order to meet the requirements of portable, digital and multi-functional electronic components, as well as production and assembly automation, electronic connectors must undergo product structure adjustments. The products are mainly developed in the direction of small-scale , low-height , narrow pitch , multi-function , long-life , surface device .
Miniaturization means that the center spacing of electronic connectors (connectors) is smaller, and high density means that the number of cores is increased. The miniaturization of consumer electronics requires components that combine miniaturization, thinness, and high functionality.
This also promotes the development of connector products in the direction of miniaturization and small spacing. The miniaturization of components places higher technical requirements. This requires a strong industrial molding foundation to effectively support it.
Now is a world where information is developing at a high speed. No matter what kind of information or technology it is for, people's requirements are getting higher and higher. From the rapid development of information and communication data, wireless interconnection has now come to each of us. From the application of technologies such as smartphones, smart wearables, drones, unmanned driving, VR practice, intelligent robots, the intelligent development of electronic connectors equipped with IC chips and control circuits is an inevitable trend. Because this will allow the electronic connector to more intelligently control the use of electronic devices, as well as improve the function of the connector itself to achieve intelligent wireless bridging. 2 Intelligent development trend 3 The development trend of high functionality
High-speed transmission refers to the timescale speed of signal transmission required by modern computers, information technology and network technology to reach the MHz frequency band, and the pulse time reaches sub-milliseconds, so high-speed transmission electronic connectors (connectors) are required .
High-frequency is developed to adapt to millimeter wave technology, and radio frequency coaxial electronic connectors (connectors) have entered the millimeter wave operating frequency band. High current is also an important development direction of many electronic connectors (connectors).
Although low-profile, lightweight, energy-saving and low-consumption are the main directions of consumer electronics products, the following two aspects have determined the evolution of power supply in the direction of high current in quite a few applications. We take common computer CPUs as an example to illustrate the reasons:
first, computer performance improves. requires an increase in the number of transistors required for the CPU to increase the computing speed, thus increasing power consumption. When the voltage remains unchanged, the current increases in the same proportion.
Second, with the advancement of semiconductor technology . The operating voltage of the transistor gradually decreases, which is beneficial to reducing power consumption, but its physical characteristics determine that the power consumption decreases less than the voltage. Therefore, the increase in current is also an important indicator for detecting the development of high-performance electronic connectors.
is resistant to signal interference and shielding. When the data transmission speed increases, the effects of capacitance and impedance become more obvious. Signals on one terminal can crosstalk to adjacent terminals and affect their signal integrity.
In addition, ground capacitance reduces the impedance of high-speed signals, causing signal attenuation. In the new connector design, each signal transmission terminal is isolated from each other. The
differential signal pair works well for this purpose because each differential signal pair has a ground pin on one side to reduce crosstalk. Generally, the first layer is an area with pins to separate adjacent ground terminals.
The next level is the ground shield installed between the rows. The top layer of using will include a metal ground structure surrounding each signal terminal. Such metal shielding completes the best combination of data transmission speed and signal integrity.
is resistant to extreme environments, reliable and environmentally friendly. In modern high-tech work, there are many connectors that are used under extreme environmental conditions. Electronic connectors can be used effectively and normally under ultra-high temperature, low temperature, vibration, hot and humid environment, and corrosive environment.
This places higher requirements on the selection of raw materials, structural planning, and processing technology for connectors. New high-temperature resistant materials, new electroplating coating processes, and more elastic alloy materials make future connectors more adaptable to harsh environments.
4 Humanized development trend
Connectors are also undergoing constant changes to adapt to their main bodies with the continuous development and advancement of multimedia and other technologies.
connector With the increasing development of science and technology, a good connector must not only become more and more beautiful and fashionable in appearance, but also have more and more durable materials, and become more and more convenient to operate. More importantly, its central part connection design To get refine and refine .
This will prevent the card slot from loosening like a normal data connector after being used for a long time. In severe cases, the data transmission part of the sub-connector will be completely paralyzed, which will greatly damage the customer's decision to purchase the main product.
Nowadays, the speed of upgrading of electronic products and equipment is very fast, which makes the development trend of connector work towards miniaturization, integration, intelligence, high functionality and user-friendly use in the future.
Only in this way can we dare to adapt to the development of the times, otherwise we will be selected by the market sooner or later.
