High frequency? High speed? How do connector products develop in the connected era?

According to the Action Plan for the Development of Basic Electronic Components Industry (2021-2023) issued by the Ministry of Industry and Information Technology in January 2021, normative guidelines for high-end improvement actions for key products such as connection components: “Connection components focus on the development of high-frequency, high-speed, low-loss, miniaturized photoelectric connectors, ultra-high-speed, ultra-low-loss, low-cost optical fiber and cables, high-voltage, high-temperature, high-tensile strength electrical equipment cables, high-frequency high-speed, high-rise high-density printed circuit boards, integrated circuit packaging substrates, Special printed circuit boards. “At the same time, with the gradual maturity of the integration technology of electrical connectors, the demand for integrated electrical connectors will become the trend of future development, and the integrated demand for integrating high power, low power and multiple signal control will gradually increase.”

(1) Development trend of electrical connector products

• The product size structure develops towards miniaturization, high density, low dwarfing, flattening, modularization and standardization;

• In terms of functional characteristics, it will develop towards intelligence, high speed and wireless;

• In terms of integration characteristics, it will develop towards multi-function, integration and sensor integration;

• In terms of environmental resistance, it will develop to high temperature resistance, oil resistance, high waterproof, strict sealing, radiation resistance, interference resistance, strong vibration resistance, strong impact resistance, high power and high current;

• In terms of product attributes, it will develop towards high reliability, precision, light weight and low cost.

(2) The technical development trend of electrical connectors

• Radio frequency transmission technology

The engineering application of 40GHz connector has gradually shown a trend of mass procurement from small batch procurement, such as: the engineering application frequency range of 2.92 series, SMP and SMPM series has been expanded from 18GHz to 40GHz. During the “14th Five-Year Plan” period, the frequency of use of research and development equipment increased to 60GHz, the market demand for 2.4 series, 1.85 series, WMP series products increased, and technology developed from pre-research to engineering application.

• Lightweight technology

With the increasing requirements of various industries for energy conservation and environmental protection, as well as the increasingly strong demand for lightweight in aerospace, weapons and equipment, communications, automobiles, consumer electronics and other fields, connector components should also achieve weight reduction under the premise of ensuring stable improvement performance, so as to achieve the purpose of reducing costs while making inertia smaller and vibration resistant. Connector housings tend to use high-strength engineering plastics with metallized appearance to replace the original metal housings, reducing weight and improving durability.

• Electromagnetic shielding technology

In the future, with the further development and integration of electronic information technology, the electromagnetic compatibility environment will be more complex and harsh, whether in high-end military electronic equipment or civilian high-speed high-frequency transmission system, electromagnetic shielding technology is still the technical direction of industry development. For example, in the new energy automobile industry, the external environment of the vehicle system is harsh, and the spectrum range, energy density and interference type are multiplied. In addition, the high-voltage/high-power power drive system in the car is highly integrated with informationized and intelligent equipment, and its electrical characteristics and functional characteristics are closely related to electromagnetic interference. Therefore, the industry has developed strict standards and test specifications for electromagnetic compatibility.

• High-speed transmission technology

In order to meet the requirements of future military weapon system development and high-speed transmission of communications, industry technology focuses on the development of 56Gbps and 112Gbps high-speed backplanes, high-speed mezzanine and high-speed quadrature connectors, 56Gbps high-speed cable assemblies, 224Gbps high-speed I/O connectors, and next-generation PAM4 transmission technology on the basis of existing high-speed connectors. High-speed products improve the vibration and shock resistance of connectors through metal reinforcement, such as random vibration from 0.1g2/Hz to 0.2g2/Hz, 0.4g2/Hz, 0.6g2/Hz, transmission from a single high-speed signal to “high-speed + power”, “high-speed + power supply + RF”, “high-speed + power + RF + optical fiber signal” mixed transmission development, to meet the needs of equipment modular integration.

• Wireless transmission technology

With the development of 5G technology, Internet of Things technology and terahertz technology, the transmission rate of wireless transmission technology exceeds 1Gbps, the transmission distance will be increased from millimeters to 100 meters, the delay is greatly shortened, the network capacity is doubled, and the module integration is getting higher and higher, which further promotes the application of wireless transmission technology. Many occasions in the communication field that traditionally use connectors or cables will be gradually replaced by wireless transmission technology in the future.

• Intelligent connection technology

With the advent of the AI era, the connector will no longer only realize simple transmission functions in the future, but will become an intelligent component that integrates sensor technology, intelligent identification technology and mathematical signal processing technology, which can be widely used in the key connection parts of system equipment to realize real-time detection, diagnosis and early warning functions of the working state of the interconnected system, thereby improving the safety reliability and maintenance economy of equipment.
