As the process of localization accelerates, an increasing number of domestic enterprises are beginning to try to replace imported connector brands such as Amphenol CDI to meet the needs of high-end equipment manufacturing fields such as aerospace, military, shipbuilding, and special equipment. However, whether domestic connectors can smoothly pass military-grade certification while achieving functional parity has become a major key difficulty制约 the further promotion of localization.
One, the application performance of Amphenol CDI connectors in the military fieldAmphenol CDI is a core high-voltage connector brand under the Amphenol Group, focusing on providing high-current, high-voltage connection solutions for heavy-duty, electric transportation, special equipment, military platforms, and other applications. The product advantages of this brand are prominent:
High-reliability connection structure, capable of withstanding shocks, vibrations, and harsh environments.
Excellent EMI shielding performance, suitable for complex military communication systems.
High sealing grade (IP67/IP69K), suitable for field systems or shipborne platforms.
Supports multi-core high-density design, enhancing wiring efficiency.
These performance indicators not only enable its wide application in the new energy and industrial fields, but also make it play a core connecting role in some military projects.
Second, the difficulties in military certification faced by domestic substitutes for connectors.Although many domestic manufacturers have the capability to develop and produce high-voltage connectors, they face many "hidden thresholds" when entering the military industry system, mainly including:
High qualification threshold for certification
Military connectors must meet the GJB national military standard, some of which need to comply with the MIL American military standard or NADCAP processing process. Many domestic manufacturers lack the corresponding production licenses and experimental testing capabilities, leading to difficulties in access.
Strict consistency requirements for materials and manufacturing
Military products require long-term batch stability, while some domestically produced substitute products still have fluctuations in material traceability, copper material consistency, and electroplating layer control.
High environmental adaptability test standards
Military platforms must cope with extreme temperatures and humidity, strong earthquakes, low air pressure, and other environmental conditions, which place higher requirements on the sealing, contact resistance, and insulation withstand voltage of connectors. The pass rate of domestic connectors in relevant tests is relatively low.
4. Long-term assessment and application verification
The military procurement process is complex and the verification cycle is long, and it often takes 1~2 years for a project to truly be finalized. Some domestic enterprises, limited by research and development investment and customer support, find it difficult to complete the entire evaluation cycle.
Solution: The Way to Breakthrough: The Upgrade Direction for Domestic Connector EnterprisesIn response to the above difficulties, excellent domestic connector enterprises are breaking through technical barriers in the following ways:
Anticipate product planning to comply with the national military standard system, and integrate the system control from raw material selection to processing stages.
Construct self-owned laboratories or introduce third-party experimental verification resources to accelerate the progress of product verification.
Strengthen cooperation with terminal complete machine manufacturers and research institutes, accumulating application experience in actual military prototypes.
Gradually obtain certifications such as " Weapon Equipment Quality Management System Certification" and "National Military Standard Production License" to prepare for subsequent mass supply.
Amphenol CDI connector represents the benchmark of high-end high-voltage connector design, and its application in military equipment has pointed the way for the domestic substitution. Although the threshold for military certification is extremely high, with the continuous progress of domestic technology and the improvement of systematic construction, in the future, there will be more and more high-quality domestic connector brands truly capable of facing off with CDI.
