EDAC was established in 1966 and is a professional connector manufacturer headquartered in Canada. Its products cover card edge connectors, D-Sub interfaces, USB/HDMI interfaces, RJ45 modular jacks, waterproof connectors, Pogo Pin spring pins, wire-to-board and customized cable assemblies. With a wide range of products, strong customization capabilities, and global services, EDAC products are widely used in industrial control, medical electronics, new energy vehicles, rail transit, and consumer electronics fields. For many domestic customers, the technical level of EDAC often serves as a reference standard for the replacement and testing of domestic connectors.
Key indicators of the domestic connector test reportWhen assessing whether domestic connectors can replace imported brands (such as EDAC), the test report is the core basis. The following indicators are particularly worthy of attention:
Mechanical property testing
● Insertion/extraction cycles: Have they reached the design requirements (such as maintaining low contact resistance after tens of thousands of cycles)?
●Retention force: whether the clamping force between the terminal and the housing is stable.
Electrical Performance Test
● Contact resistance: Ensure good conduction performance and avoid overheating due to excessive resistance.
Insulation resistance and voltage withstand test: to verify safety under high voltage or harsh environments.
●Current carrying capacity: Some EDAC D-Sub Combo can support high current up to 40A. It is necessary to focus on checking whether domestic products reach the same standard.
Environmental adaptability test
High and low temperature cycling: Maintaining stable operation under extreme temperatures.
Salt spray and humidity test: Ensure resistance to corrosion in outdoor, industrial, and marine environments.
Waterproof and dustproof rating: Whether domestic products reach IP67 or a higher rating determines whether they can be applied in harsh environments.
Reliability and Consistency
Batch-to-batch consistency: Is there an unstable yield situation?
●Long-term aging test: Simulate the performance retention after many years of use.
How to interpret these data?Many companies, after receiving the test report, only focus on "whether it passes." In fact, professional interpretation should also be combined with the application scenario:
● New energy and industrial applications: pay more attention to high current and voltage resistance specifications.
●Consumer electronics applications: pay more attention to the insertion and extraction life and size consistency;
●Medical and rail transit: In addition to performance, certification and long-term reliability should also be considered.
In other words, the test report is not only a certificate of qualification, but also an important reference for procurement strategy and selection decisions.
International brands such as EDAC have provided a reliable benchmark for the development of domestic connectors. As the technology of domestic connectors continues to improve, their performance in test reports has gradually approached and even reached international standards. Purchasers who can learn to comprehensively interpret test data from the four dimensions of mechanical, electrical, environmental, and reliability will be more confident in making the right choices in domestic substitution.
