Crimpers

[zoidberg]

No, not 'ladies hairdressers' ( or 'dressers of others' ).....

These things:

I have a 'wheen' of new, sound connections to make, from 50mm^ CSA down to 1mm^. There's confusion and uncertainty around which dies to use for what. The big ones, on big 'bare' copper crimp terminals, are obvious. Not so the little 'uns.

Can any good soul point me towards a good decode/guide as to which dies to use, when? So far, I've not found anything helpful.... and there was no FM to RT.

Thanks

The small one has dyes for varies types of crimp connectors. The ones in the pliers are for insulated connectors, the coloured dot relates to the colour of the connector you are using. The one at the bottom right is for bootlace ferrules and has the cable sizes stamped on it. You are unlikely to be needing the others for this job.

Klauke have answers

Here's a high-level menu of technical reports for you to read in your hammock.

Watch with your big crimp dies also as depending on the crimp lug type will depend how well it does the job. Some are quite thick bodied whilst others are not, so you end up with a loose crimp rectified Only by going down a die size, not ideal.

Good quality terminals is what matters. Same with your small ones; try and get the ones that don’t have a split which sometimes miscrimp or fail to grab all the strands.

I’ve also sent you the other BETA info we spoke about the other day.

Top one is big bootlace too. One on hinge is for uninsulated terminals (with two sets of flags one to hold the wire, one smaller for the electrical connection)


I can't see the middle one might be tube type uninsulated?

Have tried all the types illustrated and in all cases it seems ' one has to do it thoroughly and well, and be honest with oneself to give a good hard tug on the wire afterwards or do it again '

Wasn't ' Crimpers ' the name for pimps in Nelsonian times ?

That's my contribution.

Use what the manufacturer of the terminal specifies.
Or wing it and hope.

 

[zoidberg]

Use what the manufacturer of the terminal specifies.

I don't recall, in many years, ever seeing a manufacturer-specified recommendation on any of the pre-packed and loose-sold terminals encountered..... but I'd be pleased to be shown otherwise.

Particularly in the smaller sizes, the professional suppliers like Amp, 3M, Molex are fairly prescriptive about what to use.
When you get down below 1sqmm, it is important, as there is a fine line between getting adequate pressure in the crimp and reducing the wire strength too much.

Properly made crimps joints with the correct terminal for the wire size, done with the correct tool, are very reliable.
Amateur crimping is often not reliable.

A proper electronics lab ends up with a lot of crimp tools.

So, the source of "Don't force it - use a bigger hammer!"

and

"The Birmingham Electronics Hammer."

But as he's just doing some re-wiring on his boat, all he needs are some insulated crimp connectors and possible some bootlace ferules, in which case he only needs to wory about the two dies sets i pointed out in post #2.

I'm happy with that. Thanks, all.
