FAQ
(1) What types of connectors can be tested by the Connector Air Tightness Tester?
The Connector Air Tightness Tester is suitable for various sealed electronic connectors, including USB connectors, Type-C connectors, automotive connectors, battery pack connectors, and motor connectors. Customized fixtures can be designed according to different connector structures and sealing requirements to ensure stable positioning and accurate leakage detection.
(2) How does the Connector Air Tightness Tester detect leakage?
The tester uses the differential pressure testing method. After the connector is sealed in the fixture, compressed air or vacuum is applied to create a controlled pressure condition. The system monitors pressure changes through high-precision differential pressure sensors and determines whether leakage exists by comparing the measured value with the preset leakage threshold.
(3) Can this tester verify IP67 and IP68 waterproof performance of connectors?
Yes. The Connector Air Tightness Tester can be used as part of the sealing verification process for connectors requiring waterproof and dustproof protection. By detecting leakage caused by poor sealing, damaged seals, or structural defects, it helps manufacturers evaluate whether connector assemblies meet IP67/IP68 protection requirements.
(4) What are the advantages of using a non-contact leak testing method for connectors?
Non-contact testing helps protect sensitive connector components, including plated surfaces and precision terminals, from mechanical damage. It is especially suitable for high-precision electronic connectors where maintaining surface quality and dimensional accuracy is important.
(5) Why is the Connector Air Tightness Tester suitable for automated production lines?
The equipment supports PLC control, dual-station parallel testing, RS485 communication, and automatic data recording. These functions allow integration with manufacturing systems, improve inspection efficiency, and provide test data for quality traceability and production management.
