I bought a set of banana plugs of the style shown here (with rough 3d model to clarify the shape of the terminal because shiny metal is hard to photograph!).
The site I got them from (here) didn't go into detail and there is no datasheet, plus I cannot find any links on the googles that match this exact shape of terminal. It seems that there are many dozens of different types of 4mm banana plugs and this is a fairly rare breed.
My plan is to solder in some 14 AWG wire by first tinning the wire generously, inserting it into the hole at the end face of the terminal and then feeding more solder in through the hole in the side until the connection is full of solder.
Is that the correct way to install a wire into this kind of terminal? I think it is but I have also seen terminals that are intended for solderless connection to the cable (eg. by lacing the strands through the various holes and thus creating gas-tight connections through interference fit and friction).
I'm going to be using these for 3.3 V, 5 V and 12 V power up to max 4 Amps each (it's an ATX desktop power supply project). Edit: The PSU has overcurrent protection which kicks in at 150% rated current, and I'm going to put some 5A fuses in there too for good measure.
If this isn't the best way, could you please suggest a better method?
Also, if anyone could scare up a datasheet for this part that would be great, I'm drawing blanks at the moment.
EDIT: Further to @Neil_UK's answer, I would suggest that 14 AWG is about the biggest cable size that this type of connector can comfortably accommodate. My Weller WHS40 iron was struggling but it did manage to get the job done. Tinning the wire very thoroughly first (without increasing the diameter of the conductor) and then inserting into the terminal, then flooding the aperture with enough solder to completely fill the void resulted in a very strong joint.
If you have a 200 Watt soldering gun and a bunch of flux, then you're good to go. :)
Edit: Here's the "datasheet" if it can be called that...
