4x 4mm Banana Plug for high Loads -- 4x 4mm Bananenstecker für hohe Lasten

thingiverse

Since I'm working on a battery pack that simply provides 12V or 24V, I needed a connector that could handle high loads (24V ~250W / 12V ~180W, won't even get warm). But even higher loads should be possible! * Developed for this battery pack: https://www.thingiverse.com/thing:3748797 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! This plug has no reverse protection!!!! So please only use it if you know exactly what you are doing with it! Otherwise the whole thing ends in a firework. Use as always at your own risk... !!!Use fuses!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I have ground on the banana plugs and inserted them with superglue. Then everything was put together and glued. Now after the first successful tests I will pour out the cases still with epoxy resin, in order to be durably protected from short circuits. I have provided holes in the plug to be able to use the screw connection further. However, I strongly recommend to solder it before inserting loads >12V/5A in order to avoid contact resistances! You should also make sure that the cables are large enough! (Suitable for 4mm² and 6mm² cables ) Tip: The cheap China 4mm banana plugs like to get hot, which is due to the contact resistance of the spring. This can easily be prevented by soldering the spring to one side of the plug.
