In the electronic and communication industry, the performance of connectors directly determines the stability and reliability of the system. As a well-known Japanese brand of precision connectors, I-PEX has its products widely used in fields such as high-speed signal transmission, camera modules, display interfaces, and radio frequency communication. The特色 of I-PEX lies in its ultra-micro, high-frequency and high-speed connection solutions, such as the MHF® series and CABLINE® series, which are favored by global customers for their high stability and excellent electrical performance. However, with the rapid development of domestic electronic manufacturing, domestic connectors are gradually narrowing the gap with international first-tier brands in terms of design capabilities, production processes, and testing specifications, especially in testing standards, where domestic manufacturers are actively aligning with international norms.
Connector testing under international standardsInternational connector testing usually follows standards such as IEC (International Electrotechnical Commission), EIA (Electronic Industries Association of America), and ISO. Common test items include:
● Mechanical properties: insertion-extraction life, holding force, contact pressure.
●Electrical performance: contact resistance, insulation resistance, withstand voltage strength.
●Environmental adaptability: High and low temperature cycles, humidity and heat tests, salt spray corrosion.
I-PEX and other international brands strictly adhere to these standards, ensuring long-term stability of the products in high-speed, high-frequency applications.
The current status of domestic connector testing specificationsDomestic connector manufacturers mainly refer to GB/T (national standards) and some IEC standards for their testing systems. With the increasing demand for high-end applications such as new energy vehicles, 5G communication, and industrial control, more and more domestic manufacturers are actively improving in the following aspects:
Life span test: The plug-in and pull-out times are aligned with international high standards, increasing from hundreds to thousands of times.
2. Electrical consistency: Strengthen high-speed signal integrity testing and gradually align with the high-speed transmission capabilities of I-PEX.
3. Environmental reliability: Increase salt mist and vibration shock tests to ensure compliance with automotive and industrial application scenarios.
Comparison and Trend●Gap points: The long-term stability under extreme conditions and the control of ultra-high frequency signal loss of domestic connectors are still lagging behind international brands like I-PEX.
●Advantages: Domestic manufacturers have a clear advantage in terms of price, delivery time, and localization services.
● Trend: As domestic manufacturers continuously introduce automated testing equipment and digital quality control systems, their testing standards are gradually converging with international ones. In the future, domestic connectors will have stronger competitiveness in three dimensions: high-frequency and high-speed, miniaturization, and reliability.
The comparison between domestic connectors and international standards is not simply a reflection of the gap, but also a driving force for the continuous progress of domestic manufacturers. In terms of meeting the needs of mid-to-high-end markets, domestic manufacturers have shown an increasingly strong competitiveness.
