Content

The Connector Air Tightness Tester is a professional device used to evaluate the sealing performance of electronic connectors. Based on the differential pressure method, it detects leakage by monitoring pressure changes in a sealed system, ensuring that connectors meet waterproof and dustproof requirements such as IP67/IP68. The system provides fast, non-contact testing while protecting sensitive plated surfaces and precision interfaces.

Application

(1) Air tightness testing of electronic connectors (USB, Type-C, etc.).
(2) Leak detection for automotive connectors, battery pack connectors, and motor connectors.
(3) Waterproof and dustproof verification (IP67/IP68).
(4) Quality control in consumer electronics, automotive, and high-end manufacturing.
(5) Suitable for aerospace connectors requiring ultra-low leakage rates.

Standards

(1) IEC 60529 – Degrees of protection (IP Code)
(2) ISO 20653 – Road vehicles – Degrees of protection (IP Code)
(3) GB/T 4208 – Enclosure protection classification (reference)

(4) Communication cables (RS485).
(5) Calibration tools for pressure verification.

Test Procedures

(1) Fix the connector in the customized fixture ensuring proper sealing.
(2) Set test parameters including pressure, test time, and leakage threshold.
(3) Inject dry compressed air or create vacuum as required.
(4) Monitor pressure changes using differential pressure sensors.
(5) Compare pressure decay against threshold values.
(6) Determine pass/fail (OK/NG) and record test data.
(7) Export data for quality traceability and analysis.

Maintenance Information

(1) Regularly inspect fixtures to ensure proper sealing and avoid deformation.
(2) Calibrate sensors periodically to maintain measurement accuracy.
(3) Keep the system clean and free of dust or contaminants.
(4) Check communication interfaces for stable data transmission.
(5) Maintain stable environmental conditions for consistent testing results.

Conclusion

The Connector Air Tightness Tester provides a high-precision, fast, and reliable solution for detecting leakage in electronic connectors. With non-contact testing, dual-station efficiency, and advanced differential pressure technology, it ensures compliance with IP protection standards and enhances product reliability across multiple industries.
