In the field of high-end manufacturing, the reliability verification of connectors is an important link that affects the overall performance and safety of the equipment. Whether it is in the fields of aerospace, rail transportation, military industry, or industrial control, whether a connector can work stably often depends on whether it has gone through a comprehensive verification system. Today, taking the international high-end brand Amphenol Air LB as a reference, let's take a look at the key assessments that domestic connectors need to pass in terms of reliability verification.
Amphenol Air LB: Representative of high-reliability connectorsAmphenol Air LB is an advanced interconnect brand under the Amphenol Group, focusing on aviation, rail transit, military, and industrial fields. Its connector products are renowned for their lightweight structure, high vibration resistance, excellent sealing, and electromagnetic shielding capabilities.
In the rail transit and aviation systems, their circular connectors, rectangular modular connectors, and high-speed signal series strictly comply with international rail standards, EN, and MIL specifications. Especially in the fields of rail and aviation, their products need to withstand complex working conditions such as high vibration, temperature and humidity changes, and electromagnetic interference for a long time, and have extremely high requirements for reliability verification.
Part Two: Key Links in the Reliability Verification of Domestic ConnectorsIn order to achieve domestic substitution in high-end applications, domestic connectors must pass strict verification and testing in the following aspects to truly gain recognition from customers and the market:
Mechanical property verification
● Vibration and shock test: Simulate the operating environment of high-speed trains and aviation equipment, and test the contact stability of the connector under strong vibration conditions.
●Insertion/Extraction Life Test: Evaluate the mechanical durability and contact resistance variation of the connector after repeated insertion and extraction.
● Retention and locking reliability: Ensure that it will not loosen under high-frequency vibration or mechanical disturbance.
Environmental adaptability verification
●Temperature cycling and humidity test: Verify the sealing and electrical performance of the connector under extreme temperature changes and humidity conditions.
Salt spray and corrosion test: Especially for rail transit, marine or outdoor equipment, it examines the corrosion resistance of the housing and contact parts.
Dustproof and waterproof level (IP rating) test: evaluates the sealing protection capability of the connector under harsh environments.
Electrical performance verification
● Contact resistance and insulation resistance test: Ensure the stability and safety of transmission.
● Voltage Resistance Test: Examines the insulation performance of the connector under high voltage.
● Shielding and EMC Performance Testing: Verify the connector's protection against electromagnetic interference in high-speed signals and complex electromagnetic environments.
4. Material and Flame Retardant Property Verification
● Flame Retardant and Fire Test: Meets regulations such as EN45545 (Railway Flame Retardant Standard).
●Material aging and ultraviolet testing: examines the stability of insulating and sealing materials under long-term use.
Three, the domestic substitution practice for Amphenol Air LBCurrently, some domestic connector manufacturers have started to benchmark the design standards and testing systems of Amphenol Air LB, gradually narrowing the gap with international brands through the establishment of independent testing platforms, introducing third-party authoritative inspections, and synchronously implementing international standards.
In fields such as rail transportation, industrial automation, and new energy equipment, domestically produced connectors have already replaced some auxiliary systems and non-critical components, and have passed long-term operation verification with continuously improving reliability performance.
Whether it is an international brand or a domestic product, reliability verification is the "ticket" for connectors to enter the high-end application market. Amphenol Air LB provides a complete design and verification paradigm, while domestic brands must continuously improve in each link such as mechanical, electrical, environmental adaptation, and material performance to form a traceable and verifiable quality system in order to achieve true substitution.
