How to Test the Quality of Waterproof Plug Terminal Connections

If you are using waterproof plugs, make sure they are good quality as this can be an area were problems arise. We'll discuss a few simple methods to see just how well these waterproof connections are working.

Ensuring That Things Connect Solidly:

For snug fitting of any waterproof plug connections, just be sure to tighten both male and female connections. There ought to be no wiggling or crevices. A snug fit can help prevent water from infiltrating, which can lead to damage or electric shock.

Signs of Bad Waterproof Connections:

Bad waterproof connections can be identified if you find any damage. If the plugs and the terminals are rusty, corroded or look worn, they may not be safe to use. Also, if the plugs and terminals do not engage properly, they are best replaced.

Reliability of Testing Connections:

You can test the reliability of waterproof plug connections by contact resistance test. This is a test that measures how well all the connection works. Resistance of a proper connection should be small. If the resistance is high, that might suggest a bad connection that needs to be replaced.

Why You Should Insulation Test:

Insulation Resistance – Testing this will be the next step that must not be overlooked. This test measures how much the material surrounding the junction prevents water from penetrating. High insulation resistance indicates the connection is in good cover. Low resistance, among other things, can lead to problems like short circuits.

Quality Checking with Water Test:

Finally, water tests can be performed to verify the quality of the waterproof plug connection. Dunk the plug and terminal briefly in water and see if any gets in. (Correct connections should remain dry. If water gets inside, that indicates the connection may be bad and should be replaced.
