In actual projects, many engineers encounter a key issue when considering the replacement of international brands such as Molex with domestic connectors: how to understand the connector test reports? Test reports are an important basis for evaluating whether domestic connectors have the ability to replace, especially in high-reliability application fields such as new energy vehicles, industrial control, and communication equipment. Without reliable data support, the replacement of domestic products may involve risks.
Why is the Molex connector test standard so "hardcore"?
Molex as a globally leading connector brand, its products are widely used in high-end markets such as automotive electronics, industrial automation, and medical equipment, with extremely strict standards for product testing and certification. For example, its classic MX150, Mini-Fit, Micro-Fit, mPwr and other product series must pass strict:
Terminal holding force test
Contact Resistance Test
High and low temperature cycle test
Salt spray corrosion test
● Vibration and Impact Testing
Insulation resistance and voltage withstand test
These test items ensure that Molex connectors can maintain stable performance under extreme conditions such as high temperature and humidity, vibration and shock, and high current transmission.
Second, the common structure of domestic connector test reports
For users who want to replace Molex connectors with domestic products, it is essential to carefully understand the data of the following test items:
Material and structure information
Is the plastic material (such as PBT, PA66) flame-retardant?
Terminal material (copper alloy, tin/ gold plated surface) meet the standards?
Electrical performance test
●Is the contact resistance ≤20mΩ? (Affects conduction stability)
Is the insulation resistance ≥1000MΩ? (To prevent leakage)
● Can the voltage withstand test withstand AC1500V/60s?
Mechanical property testing
● Insertion force test: Is insertion smooth?
Terminal retention: prevent wire from falling out under vibration
● Vibration Test and Impact Test: Have you simulated the mechanical stress environment of automotive grade?
4. Environmental reliability test
●Durability test under high temperature and high humidity (such as 85℃/85%RH)
Salt雾test: Corrosion resistance is crucial for vehicles and industrial products.
● Thermal cycle test: Suitable for new energy vehicles, outdoor equipment
Domestic connectors can be used, the test report is the judge!
Before the mass application of domestic connectors, the test report is your most important "technical guarantee." Not only should you check if the tests have been conducted, but also pay attention to whether the testing methods are standardized, whether the standards are compatible, and whether the data is stable. If you are a novice engineer, it is recommended to ask manufacturers to provide complete type test reports and batch consistency test reports before selection.
