Against the backdrop of large-scale deployment of 5G, explosive growth of AI computing power, and accelerated pre-research of 6G technologies, seamless, high-speed, and stable connectivity has become the core infrastructure for global business operations. From enterprise data centers and outdoor communication base stations to intelligent vehicle-mounted systems and aerospace equipment, nearly all core communication scenarios rely on electronic connectors. As bridges for circuit interconnection, the performance of electronic connectors directly determines the stability and efficiency of communication links. Performance degradation, improper selection, or other related issues can not only cause device freezes and communication interruptions, but also trigger chain reactions such as production halts and business losses. Therefore, a thorough understanding of the technical trends, performance requirements, and selection logic of electronic connectors is of great significance for enterprises to upgrade their communication systems and ensure business stability.

I. Core Value Reconstruction: From “Transmission Carrier” to “System Performance Support Core”

In the past, the core positioning of electronic connectors was to achieve simple circuit conduction. With the iteration of communication technologies, however, their value has evolved from a “basic transmission carrier” to a “core system performance support component”. Today, diverse application requirements—such as high-density interconnection for AI servers, high-frequency signal transmission for 5G base stations, and extreme environment adaptation for vehicle-mounted communications—have imposed four-dimensional demands on electronic connectors: high-speed, miniaturization, integration, and intelligence.

This transformation is mainly reflected in the innovation of three core components from a technical upgrading perspective:

1. Contacts: As the core components for current and signal transmission, high-end connectors generally adopt high-quality plating materials such as gold-nickel alloys. This not only significantly enhances wear resistance and conductive stability, but also reduces signal attenuation and interference during transmission through the design of redundant contact interfaces, enabling stable adaptation to high-speed data transmission scenarios.
2. Insulators: High-performance materials with low dielectric loss are selected to precisely control the spacing and alignment accuracy of contacts. Meanwhile, these insulators boast excellent high-temperature resistance and anti-aging properties, effectively solving insulation challenges in high-frequency signal transmission and ensuring the purity of communication links.
3. Shells: Breaking away from the single function of traditional protection and fixation, shells are now equipped with multi-layer electromagnetic shielding structures to effectively resist external electromagnetic interference. They can also adapt to complex environments such as extreme vibration, salt spray corrosion, and alternating high and low temperatures. Some products are integrated with quick-locking mechanisms to simplify installation procedures and improve operation and maintenance efficiency.

II. Four Core Performance Dimensions: Adapting to Emerging Requirements of Current Communication Scenarios

With the diversification and complexity of communication scenarios, the performance evaluation criteria for electronic connectors have expanded from the traditional dual system of “mechanical + electrical performance” to a four-dimensional system covering mechanical, electrical, environmental, and intelligent performance. Each dimension corresponds to clear application requirements:

1. Mechanical Performance: Core indicators include insertion and extraction force, mechanical service life, and high-density adaptability. By optimizing contact structure design and plating processes, high-quality connectors can control insertion and extraction force within a reasonable range while extending mechanical service life to over 10,000 cycles. For high-density installation scenarios like AI servers, they can achieve compact layout with more than 100 pins, saving internal device space.
2. Electrical Performance: Key focuses are high-speed transmission capability, signal stability, and anti-interference performance. Current mainstream high-speed connectors can already meet high-bandwidth transmission needs and will evolve toward higher transmission rates in the future. Meanwhile, optimized contact resistance design and electromagnetic shielding technology effectively reduce signal attenuation and crosstalk, ensuring communication quality in high-frequency and high-speed scenarios.
3. Environmental Performance: For complex scenarios such as outdoor base stations, vehicle-mounted communications, and satellite communications, connectors must feature wide temperature adaptability (ranging from -55℃ to 125℃), resistance to strong vibration and shock, and protection against salt spray corrosion. Some high-end products also need to meet IP68-rated waterproof and dustproof standards to ensure stable operation in extreme environments.
4. Intelligent Performance: As an important upgrading direction emerging after 2023, some high-end connectors are embedded with micro-sensors to monitor real-time operating parameters such as temperature, humidity, and contact status. Predictive maintenance can be realized through data feedback, significantly reducing operation and maintenance costs and downtime risks in scenarios like industrial Internet of Things (IIoT) and data centers.

III. Selection Guide: Three Core Principles to Avoid Selection Risks

The performance upper limit of a communication system largely depends on the accuracy of connector selection. Combining current industry trends and application requirements, enterprises should follow three core principles when selecting high-reliability electronic connectors:

1. Prioritize Technical Adaptability: There are significant differences in requirements across different communication scenarios. For example, AI servers require connectors with high-speed transmission and high-density layout; vehicle-mounted communications demand specialized models resistant to vibration and high temperatures; outdoor base stations call for connectors with high protection levels. During selection, it is essential to accurately match the transmission rate, frequency, and environmental protection requirements of the application scenario to avoid over-specification or underperformance.
2. Base Selection on Quality Stability: Prioritize manufacturers with sophisticated manufacturing capabilities. Such enterprises implement stricter controls over material selection and production processes. Their products not only comply with international environmental and quality standards such as EU RoHS, but also ensure consistency in mass delivery, reducing the risk of subsequent equipment failures.
3. Balance Innovation and Compatibility: Communication technologies evolve rapidly. When making purchasing decisions, attention should be paid to the manufacturer’s technological iteration capability. Priority should be given to products supporting modular upgrading and standardized interfaces, which facilitate subsequent system expansion and reduce the costs of equipment upgrading and replacement.
