In the connector industry, L-com is a globally renowned interconnect solutions supplier, with products covering multiple fields such as Ethernet, radio frequency, fiber optics, industrial connectors, and custom cables. Its products are widely used in communication, data centers, industrial automation, medical equipment, military, and aerospace applications. L-com is known for its rich inventory, fast delivery, and flexible customization capabilities, which make it highly valuable in terms of connector reliability and testing standards.
With the acceleration of the domestic substitution trend, more and more domestic manufacturers are referring to international standards in the process of research and development and production to ensure the scientificity of the testing process and the reliability of the results. This article will combine the experience of the L-com brand to analyze the testing process standards of domestic connectors and share some case studies.
One, Standard for Domestic Connector Testing Process1. Appearance and Dimension Inspection
●Ensure that the connector structure and dimensions meet design specifications through devices such as three-coordinate measuring instruments and calipers.
Check the evenness of the coating, the integrity of the insertion pins, and the anti-stupid structure, etc.
Electrical Performance Testing
● Contact resistance test: Verify the low resistance value between terminals and conductors to ensure stable signal transmission.
Insulation resistance and withstand voltage test: Ensure that the connector does not puncture under high-voltage environment, meeting safety requirements.
●Insertion force and mechanical life test: Test the durability of the connector through cyclic insertion and extraction experiments.
Environmental reliability test
High and low temperature cycle test: Simulate work stability under different temperatures.
Salt mist and humidity test: to examine the anti-corrosion and moisture-proof capabilities.
● Vibration and shock test: verify the vibration resistance performance under transportation and application environments.
4. Functional testing
Perform standing wave ratio (VSWR) and insertion loss tests on RF connectors.
Verify the transmission rate, delay, and anti-interference performance of network cables.
Case AnalysisFor example, replacing the L-com Cat6 industrial connector with a certain domestic Ethernet connector:
Test procedure:
● Conduct contact resistance and size comparisons during the R&D stage to ensure compatibility between domestic parts and original factory parts.
●The environmental laboratory conducted a 240-hour salt spray test on it, and the results show that the nickel-plated shell has good protective performance.
● The insertion and extraction life test still maintains a stable contact resistance after over 800 cycles.
● Result Analysis:
Domestic parts have not only achieved complete replacement in terms of appearance and dimensions, but have also reached the L-com standard in electrical and environmental reliability, meeting the conditions for mass production.
This case shows that through a scientific testing process, domestic connectors can not only narrow the gap with international brands but also demonstrate greater advantages in delivery time and cost control.
Domestic connectors must strictly implement scientific testing procedures to truly replace international brands (such as L-com), covering multiple dimensions including appearance, electrical, environmental, and functional aspects. Only by ensuring that there are standards to follow at every stage can high reliability and consistency in product delivery be achieved. Case studies show that domestic substitution already has mature verification capabilities and will welcome a broader application space in the future.
