Connector airtightness is the cornerstone of a stable electrical system, especially in harsh environments.As an expert in the field of hermeticity testing for many years, Precision Engineering provides you with professional and efficient connector hermeticity testing system solutions to ensure that your connectors can maintain excellent reliability under various challenges.
- Harsh Environment Electrical Connection Guarantee:Humidity, dust, corrosive gases, temperature changes and other harsh environments, poor airtightness will lead to contact corrosion, insulation degradation, signal interruption and other faults, threatening the safe operation of equipment.
- Prevents intrusion of environmental agents:Effectively prevent water vapor, dust, corrosive gases, etc. from intruding into the connector to avoid performance degradation.
- Water vapor:Condensation reduces insulation and accelerates metal corrosion.
- Dusty:Obstructs electrical contact and increases contact resistance.
- Corrosive gases:Accelerated aging damage to components.
- Maintains signal integrity:Environmental media intrusion changes the connector dielectric constant, affecting the quality of high-frequency, high-speed signal transmission and reducing data transmission accuracy and stability.
- Conforms to industry standard specifications:Meet the strict airtightness standards and specifications of automotive, military, communications and other industries to ensure product compliance.
First, the specific process of connector air tightness testing
Pressure decay method is a common and efficient method for connector airtightness testing, Jingcheng Industrial Technology explains the key steps for you:
Energy Storage ConnectorsDual-channel airtightness tester
1.1 Preparatory phase:
- Criteria Confirmation:Specify the IP rating or corporate standard and define the test parameters.
- Equipment inspection:Ensure that testing equipment (airtightness meterThe air supply, air source, fixture, etc. must be in good condition, accurate and reliable, and the air circuit must be free of leaks.
- Workwear preparation:Customized special tooling to ensure sealing, fast loading and unloading, accurate positioning, material compatibility and durability.
- Parameter Settings:Set key parameters such as test pressure, holding time, test time, leakage determination threshold according to standards and products.
1.2 Test execution phase:
- Product Placement:Hold the connector gently to ensure that it fits perfectly with the workpiece seal and is placed in place.
- Initiate the test: activate (a plan)airtightness meterThe device automatically executes preset programs:
① Clamping:The tooling automatically clamps the sealing connector.
② Inflatable:Slowly inflate to set pressure.
③ Pressurization:Maintain pressure stabilization.
④ Detection:Precision sensors monitor pressure changes.
⑤ Exhaust:Slowly vent to atmospheric pressure. - Data Acquisition and Analysis: airtightness meterReal-time pressure data is collected, automatically analyzed to determine Pass/Fail, and complete test data is recorded to generate a report.
1.3 Post-testing phase:
- Results Record:Automatically records test results (judgment, leakage rate, pressure curve, etc.), generates reports, and exports or interfaces with MES/QMS systems for quality traceability.
- Disposal of non-conforming products:Nonconforming products are isolated and marked, the cause is analyzed and corrective measures are taken, the products can be reworked and retested, and the products cannot be reworked and scrapped.
- Equipment maintenance:Regular cleaning, inspection, replacement of wearing parts, calibration, lubrication, to ensure long-term stable and reliable operation of the equipment.
Second, how to choose the right connector air tightness test method?
Consider the following factors to choose the optimal solution:
2.1 Airtightness rating requirements:The higher the IP rating, the higher the sensitivity requirements.
2.2 Application Scenarios:Harsh environment applications require higher airtightness.
2.3 Batch and efficiency:Fast and efficient methods (e.g., pressure decay) are preferred for mass production, while high-precision methods (e.g., differential pressure, tracer gas) can be considered for low-volume production/research and development.
2.4 Budget for testing costs:Balance the cost of equipment, operation and maintenance, and choose the most cost-effective solution.
2.5 Level of quality management:High-standard companies tend to favor more rigorous and sophisticated testing methods.
