Question about flex wire strands on plug terminal

[john2k]

Sorry this might be a bizarre question but hope someone can help: When you open up a plug of an appliance or device that is fitted with a plug, the flexible strands of wire that go into the terminal that get screwed down have some sort of solid copper sleeve crimped to keep them together. So if I was wiring a fresh flexible cable and stripped the wire to expose the strands, is there any product to use that does the same thing instead of putting loose twisted strands inside the terminal?

They are called ferrules.

You will need the correct size and a proper crimper.

There don't seem to be any non-insulated ones on that page.

Kit I got from Lidi, the problem with over centre crimp pliers is they are designed for one make of crimp. Only one firm that I worked for, calibrated crimp pliers (GEC Large Steam Turbines) and they did not even use the same pliers for red, blue, and yellow crimps, never mind exchangeable heads.

For pre-insulated terminals which would not work in a plug, we get cheap crimp pliers which rely on the user to decide how hard to crimp

but not seen the cheap pliers (£6) for the pin crimp. this is more than I wanted to pay just for pin crimps, which is why I grabbed the one on sale in Lidi. In the main if you twist the strands together there is no real problem not putting a pin crimp on the strands.

It's a bootlace ferrule you need. If you look at the ends of shoelaces you will see they have a plastic version to prevent fraying. There is a particular crimper for them, I have one, they are not common. A ordinary crimping plier might manage.

I find uninsulated ferrules easier to do well. You can get a slide- on insulating cover if you need it.

if you are careful and have a steady hand you can put the ferrules with the plastic bit on backwards then cut the plastic bit off but there is usually enough room in a plug to fit them the right way
