Amphenol Alden replacement connector domestic aging test strategy

In the field of medical connectors, stable and reliable performance ensures safety of life. As an innovative leader in the medical connector field, Amphenol Alden integrates rigorous aging test processes into product design, providing a solid foundation for high reliability. Below, we will share the experience of this brand and discuss the coping strategies of domestic connectors in terms of aging test methods and actual effects.

Learn from Amphenol Alden's testing system and technical capabilities
Amphenol Alden emphasizes "Process Validation" in its product development process, covering multiple assembly techniques such as adhesive and epoxy resin application, overmolding, crimping terminals, and relies on high-precision testing equipment for repeated measurements. Each component must meet design standards to ensure consistency and lifespan performance.
The verification process includes:
● Mechanical and electrical performance testing;
●Optimization and statistical analysis of industrial parameters;

Process stability control ensures long-term reliability of products.

Secondly, suggestions for aging test methods of domestic connectors
To meet the quality requirements of imported brands, domestic connectors can refer to and implement the following testing procedures:
High-temperature aging: The connector is subjected to continuous aging at a temperature higher than the operating environmental temperature (such as 105 °C) for several hundreds of hours (recommended ≥300 hours), followed by the measurement of contact resistance change and appearance status.
●Judgment criteria: The change in contact resistance should be less than 5 mΩ, and there should be no physical damage.
●Reference specification: The contact resistance of Amphenol products changes by less than 5 mΩ after high-temperature aging.
2. Vibration and shock testing: Perform random vibration tests (such as standard EIA-364-28) and mechanical shock tests (such as 30 g, 11 ms, multi-axis repeated shocks) to ensure stable contact performance and no structural damage.
Environmental tests: including dustproof, corrosion resistance (mixed flow gas test), etc., to evaluate the service life and reliability under harsh environments.

4. Electrical voltage resistance and insulation testing: Conduct high-voltage resistance tests on each pin (such as 550 V AC), and measure leakage current and insulation resistance to verify the insulation performance.

Three, domestic testing implementation effect and optimization suggestions

Through the above standard test, if the domestic connector can maintain contact resistance change <5 mΩ, no abnormality in voltage resistance, intact mechanical structure, and no performance degradation after vibration and impact, it indicates that it has reached a relatively high level in terms of durability and stability. This quality verification based on rigorous aging test data lays a foundation for product promotion and customer trust.

Aging tests are the core link in ensuring the quality and lifespan of connectors. By referring to the process verification concept of Amphenol Alden and combining multi-dimensional testing methods such as high temperature, vibration, electrical, and environmental tests, domestic connectors can achieve breakthroughs in reliability and win customer trust.
