1.7mm x 4.0mm Plug For AC Adapter
Are there parts to rebuild the wire this adapter fits?
I am a truck driver and the constant jiggling of this weak wiring has caused me to need a new charger several times and from the charger to the wall is fine but now I have several of them because I can't seem to find the parts to build a sturdy heavy duty wire from the charger box to the computer plug. The wire has broken or melted several times just before this plug. Please help. The wiring is so weak that just plugging it into the computer weakens it, whether it's ever turned on or not. The act of plugging it into the wall damages it by heat. The only way this unit ever is OK is if you never use it. I want parts to build my own.
First off this plug (120-090) does not work with the Universal Laptop PS you have in your related questions. This plug has two prongs the laptop supply is much more complicated of a fix to put on this size plug.If your wire is getting too hot, then the object you are powering is probably asking for more amperage then the power supply can provide. A wire that gets too hot is very dangerous and cause shorts and fires. It might be a good idea to get a manufacture ps made for your device, or look for one that is able to supply more than 90 watts.Now if you are still having problems with wire breakage after the strain relief of the plug, I suggest getting some vinyl tubing from your local hardware store (it will be in the plumbing section, and its normally used for water supplies to your ice cube maker in the fridge. its relatively inexpensive for long sections). Then also getting Rubber Splicing Tape (otherwise known as Cold Shrink Tape). PE carries it, but so do the box stores usually in a name brand. You might be temped to use Electrical tape, but don't it will just eventually slide off. Cut the tube to length of your wire(Longer is better: You can always cut off excess, but its harder to put on more), then cut a slit down the entire length of the tube. Starting at the strain relief start feeding the wire into the tube. Now use the Cold Shrink Tape to bond the ends to the strain relief. If you want, you can cover sections of the tube to keep the wire from sliding out, but you shouldn't need to do the hole thing. Now your entire wire is strain relieved and should be much more sturdy.I use this trick on my clearance phone charging cables in my car. The the tubing gets very pliable in the summer, but I still haven't had an issue. Even still I have another 20ft of tubing lying around if I need it.I hope this helps and best of luck finding a suitable power supply. Please feel free to answer your own question with more questions you might have. I'll keep checking back.
