DIY Magnetic Jack/Plug for Any Purpose (No Soldering)


Introduction: DIY Magnetic Jack/Plug for Any Purpose (No Soldering)

Hello friends..

Watch the video to see how it works in action here:

Step 1: How It's Done..

After designing the jack, and 3D printing it, put a drop of a glue under the magnet, then insert the copper sheet and bend it in both ways as you see in the pictures. drill a hole where the screw should go (in the copper sheet) Use metal M3 screws to fix the wires that you will connect..

This design is for a 1mm thickness/5mm diameter magnet.

If you want my STL file of the design, just drop me a comment.

Happy connecting!

    As you see in the video, you can choose if you want it to attract in both ways or only one way like mine..

    That's awesome man, excelent ideea.

    I have a car camera and i'm afraid to keep plugging on and off the power connector as it will eventually tear.

    I tried the 5 pin usb cable you are showing in the video, but it cannot get enough power to the device (connecting to a smartphone and using ampere it gives max 500 mah).

    This should ensure enough juice for the camera.

    How can i get my hands on 1 or 2 plugs?

    Thank you :)

    Thank you! Glad you liked it :)

    Actually I have the 5 pin usb magnetic jack, and it gives more than 500 mah, maybe you just didn't get lucky with that one.. What I showed in the video is the built in Mac charging cable that comes with all Macbooks.

    Send me a message Where do you live so we can communicate and see how to fix this :)

    This is the same principle, but a bit more "vintage", than the power connector of Macbooks.

    Actually they use moving needles, and one magnet side with another metal side.. I like my design more (not because I made it) but because it has no moving parts with the ability to make it goes only one direction or both :)

    Hope you liked it :)

    Hi Rajaa,

    This is so F'in brilliant for easy hook up and would be good for quick disconnect power to breadboards and the like as well - extremely nice!

    Gotta find a way to make something like this without a 3D-printer :)

    Talk to you later.

    Hi nabo!

    I'm glad you like it! exactly, it's extremely useful in these cases..

    If you want, I can make a few of them and send them to you with magnets by post.. Just let me know if so :)
