Intro: Repair Male Plug of Dental Handpiece Using Sugru
This plug had a cable that had been pluged out by force many times, so eventually it had all seven inner cables making a shortcut with each other and causing the handpiece not to work at all. So with some drops of super glue and a piece of sugru I managed to isolate the inner cables and stabilize the plug. This should probably have saved the dentist more than 123 euros with VAT.
Take a look at how simple it is.
Step 1: Check If All Pins Are Working Properly
To do this just use a multimeter in buzzer mode and check the conductivity for each pin.
In my case all worked just fine...lucky me!
Step 2: Use Super Glue to Isolate Inner Cables
This step is easy but also takes some time.
For each inner cable use a drop of super glue twice and wait each time to dry. This way you make a simple isolating layer.
Step 3: Optimize Stability and Isolation (sugru First Step)
Step 4: Fill With More Sugru
Use some extra sugru and close the fist cap that cover the cables. If any sugru comes out wipe it out. Than just wait for 24 hours for sugru to cure.
Step 5: Assembly the Socket
Just assemble back the socket and go on and test it.
