Description

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!

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.

Da ich gerade an einem Akkupack arbeite das einfach 12V oder 24V zur Verfügung stellt, brauchte ich einen Stecker der hohe Lasten verträgt (24V ~250W / 12V ~180W, wird nicht mal warm).

Es sollten aber noch höhere Lasten möglich sein!

Dieser Stecker hat keine reverse Protection!!! Also bitte nur verwenden wenn ihr genau wisst, was ihr damit macht! Sonst endet das Ganze schnell mal in einem Feuerwerk. Verwendung wie immer auf eigene Gefahr...

!!!Benutzt Sicherungen!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Die Bananenstecker habe ich angeschliffen und mit Sekundenkleber eingesetzt. Dann alles zusammengesetzt und verklebt. Jetzt nach den ersten erfolgreichen Tests werde ich die Gehäuse noch mit Epoxidharz ausgießen, um Dauerhaft vor Kurzschlüssen geschützt zu sein.

Ich habe Löcher in dem Stecker vorgesehen um die Schraubverbindung weiter nutzen zu können. Ich empfehle aber dringend bei Lasten >12V/5A dieses vor dem Einsetzen fest zu verlöten um Übergangswiderstände zu vermeiden!

Zudem solltet Ihr darauf achten die Kabel ausreichen groß zu dimensionieren! (Für 4mm² u. 6mm² Kabel geeignet )

Tipp: Die billigen China 4mm Bananenstecker werden gerne heiß, was am Übergangswiderstand der Feder liegt. Das kann man aber leicht verhindern in dem man die Feder auf einer Seite am Stecker festlötet.
