Hi,
I use those quick disconnect terminals a lot, the kind that mate with the opposite gender and are often found on mid sized Lead Acid batteries like 7Ahr sizes. I believe they are sometimes called "F" connectors. They push on and pull off.
My problem is that no matter what terminal i use, the wire always manages to break off eventually.
I found that this is caused by the wire entry point, where it enters the terminal top where it is crimped or soldered.
The wire used is almost always stranded because it has to flex a little.
There are several different kinds of terminals in that they have different shapes where the wire enters the terminal top. Most are crimp type, and you crimp the wire strands themselves (the copper strands) and anther crimp for the insulation. These kind are better than the kind that dont have that second crimp for the insulation, but they are still not quite good enough.
The type that solder or if you just decide to solder the wire on that's even worse as the wire breaks at the point where the wire enters the solder.
What i did was create a terminal with a large metal protrusion at the top, where you can wrap the wire around it at least once before soldering the end. This means the insulation plays a bigger role in absorbing some of the flax and some of the strain if the wire is pulled a little. It ends up looking funny, but it works.
What i was wondering is if anyone has seen anything like this for sale around somewhere? I would like to buy some nice commercially made units if possible. I recently bought some larger ones that i can modify myself, but i would prefer to get something ready made and nice and strong.
Thanks
