Crimp Connections

[James]

How do people make of insulated crimp connections?
Just wondering because I have come across many different methods in the field.
some good, some not so good.

Used a pair of pliers when I was soldering some connector pins to some wires.. Only 5V though.
That first bit doesn't make sense.... I crimped the wire to the pin using pliers then soldered it, for a better connection...

I've always used a ratchet crimping tool for crimps got given several different pairs for various crimps as an apprentice and have only ever used them. Not had one fail in 20years that I know about

I am guilty of this - hammered a lug onto a 70mm EQ bond because I forgot the hydraulic crimper

Not sure what this poll is about?
In the past, I’ve used all manner of things to make crimp connections, pliers, side cutters, solder, cheap crimp tools, even my Swiss Army knife.
Now I only use the correct ratchet crimper.

Probably made a sound connection if just a little barbaric

The purpose of the poll was to try and gauge how many people do it properly, I made it anonymous so I stood a chance of getting close to the truth.
I have come across a few in line crimps in industrial DB's lately that have fallen apart when handled.
closer inspection has shown either plier type marks or cutter type marks.

I have used a decent pair of ratchet crimps for years now myself and never had a joint fail.
I have yet to see a well made joint by any other means.

You can make quite a good crimp using the cheap crimpers, if you have the strength.
With the Japanese style non-insulated crimps, I have in the past re-used them by opening up the folded over parts and either re-closing them onto new wire, or soldered the new wire to the body of the crimp and just folded over the bits that grip the wire insulation.
On larger lugs, I have in the past used a blunt 6 inch nail and also a larger pin punch.
