Connectors are an indispensable core component in electronic systems, and their quality and reliability directly affect the operation of the entire machine. As a globally renowned connector brand, JST is widely used in fields such as automotive electronics, industrial automation, rail transportation, and new energy. With the acceleration of the domestic substitution process, how to analyze the quality and reliability of domestic connectors through test reports has become an important issue for engineers and procurement personnel.
One, quality characteristics of JST connectorsJST products are renowned for their small spacing, high reliability, and stability:
Miniaturization and high-density design: meet the strict requirements of space utilization in industrial control, consumer electronics, and other fields.
Terminal plating and material technology: improve weldability, conductivity, and corrosion resistance.
●Environmental adaptability: Some products have waterproof and vibration resistance properties, suitable for harsh industrial environments.
These characteristics need to be verified and compared specifically during the testing process.
Part Two: Skills for Analyzing Domestic Connector Test Reports1. Appearance and Dimension Inspection
Check the terminal size, insertion gap, and plating condition of the pins.
●Ensure compatibility with JST standard models to avoid assembly interference.
Electrical performance test
● Contact resistance: Test the resistance change before and after the plug-in, to judge the conductivity stability.
Insulation resistance and voltage resistance: Ensure no leakage occurs under high voltage or harsh conditions.
3. Mechanical property testing
● Insertion and extraction life: Simulate repeated insertion and extraction to evaluate service life.
● Retention and vibration resistance: Verify whether it will loosen during the operation of industrial equipment.
4. Environmental and Reliability Testing
● High and low temperature cycling: examines the thermal stability of the material.
Salt spray test: to test corrosion resistance, suitable for rail transit and new energy environment applications.
5. Key Points of Data Interpretation
● Compare the gap between domestic samples and JST original samples, and find the key improvement points.
Pay attention to the volatility data under different test conditions and analyze the existence of consistency risk.
The domestic connector must pass strict electrical, mechanical, and environmental tests to truly replace JST in applications. By deeply analyzing the test reports, it is not only possible to quickly determine whether the product meets the application requirements, but it can also help the R&D and procurement teams make more reasonable decisions when selecting models.
