Cleaning and maintenance is another important part of maintaining IP68 waterproof connectors. The following are the precautions for cleaning and maintenance:

Clean the surface: Using a soft cloth or brush, gently remove dirt and dust from the connector surface. Avoid using corrosive cleaners or metal brushes to avoid damaging connector surfaces or seals.

Seal maintenance: Check the condition of the seal to ensure that it is not aged, damaged or deformed. If the seal has these problems, it should be replaced in time. Before installing new seals, ensure that the seals are kept dry and clean to avoid introducing contaminants during installation.

Lubrication treatment: For connectors that require lubrication, lubricate with a suitable lubricant. The lubricant can increase the smoothness of insertion and removal, reduce wear and friction, and thus extend the service life of the connector. However, it is important to note that not all connectors require lubrication. Therefore, before lubrication, be sure to consult the connector's manual or consult the manufacturer's recommendations.

3. Regular check and test: to ensure the stability of the connector performance

In addition to daily inspection and cleaning maintenance, IP68 waterproof connectors should also be inspected and tested regularly to ensure that their performance is stable and reliable. The following are the contents of regular inspections and tests:

Electrical performance test: Use professional testing instruments to test the electrical performance of the connector. Including insulation resistance, contact resistance, compressive strength and other indicators. These tests can help identify potential electrical faults and ensure that the electrical performance of the connector meets the design requirements.

Mechanical performance test: Check the connector insertion and withdrawal force, locking force and other mechanical performance indicators. These tests assess the mechanical properties and durability of the connector, ensuring that it does not become loose or damaged during long-term use.

Environmental adaptability test: Place the connector in a simulated harsh environment for testing, such as high temperature, low temperature, humidity, etc. These tests can evaluate the performance and stability of the connector under different environmental conditions, ensuring that it will work properly in practical applications.

IP68 waterproof connector Common connector failures and their causes

Although the IP68 waterproof connector has excellent water and dust resistance, it may still fail during long-term use. The following are common connector failures and their causes:
