Soldering Wire

Okay so the magical non crush connectors are crush connectors.

I don't understand where you're getting that from. The pre-insulated crush connectors shown previously are a variation of crimp connector which is convenient but does not do a very good job.

Because you are making a distinct that doesn't exist. Either you CRUSH the wire between two metal surfaces or you SOLDER the wires to fuse them together.

There is nothing else. Or at least nothing different that anyone's shown on this thread or that I've even seen. Still I'm not dead yet and PH may still prove illuminating.

Have often used both methods for joining conductors, proper fold type crimps and soldering

Soldering has always proved to be more reliable yet more time consuming, never ever have witnessed a good soldered joint fail

Witnessed plenty of failures with crush-ons due to the conductors not being grabbed properly or them being broken at the crush similar to what wire cutters achieve, the crush does sometimes become a cut

Had some failures with proper fold type crimps due to the conductors being cut

Doubt a good soldered joint will ever be beaten, can't see how one could be beaten as long as it's correctly insulated with adhesive heat-shrink

Manufacturing is all about cost, DIY doesn't cost anything

Solder for the DIYer is good

Stopit posted some pictures of a style of crimp connector referred to as a crush connector. These do not have the conventional tabs that fold around the wire and can be crimped to it. Instead they have a round section opening which can be mashed down into an oval section to grab onto the wire. They're pretty naff. I much prefer the 'proper' style of crimped connector with separate tabs. This is the distinction I'm making between crush connectors and crimp connectors.

Couldn't agree more.

When people mention NASA, Boeing, BOAC, BEA etc they always fail to mention that their industrial equipment costs about three gazillion quid, they do not go to Halfords and buy some awful badly made crushing device for one shilling and sixpence.

Also don't forget that they frequently use aluminium wire due to weight restrictions & that responds very differently to copper when soldering.

Although it was me that posted the NASA PDF, imagine going up in a rocket built with these bad boys:

Mmmmm, part of the problem is that many people class these as crimp type terminals

I didn't click that link, but you wouldn't get me on one of them sky rockets if the electricals were done with those.

Being serious I sometimes see a nice kit car where someone's put a lot of time and effort in spoilt by those awful blue crimps everywhere. Obviously everyone is different but I couldn't have that, I'd have to redo them all so at least they look professional.

Having been educated by the super-glued clutch plate topic, it would be great if some company or other produced cable glue

Edit

Mmmm silly me, what was I thinking of

Someone many years ago produced a cable glue known as solder

As someone who solders more pipes than wires, I've seen a glue product masquerading as a replacement for plumbing solder... Every test of it I've seen reveals it works, to a point, but is generally ste by comparison to solder.

The other nearest thing I've seen to "cable glue" is conductive epoxy. Also I've tried out a paste solder that came in a little syringe when I was doing some SMD soldering - really needs a heat-gun I suspect, I found it difficult to control when I used it with a very fine iron (yes, I realise soldering irons aren't advisable for SMDs but I can do it with a very fine tip, fine solder wire and a good flux )

Couldn't point me at where to get the good crimps could you? I've got decent ratchet crimpers but when I do the yank test I have about a 50% success rate with the insulated crush-type.

Life would be too easy if some of this gear worked properly, wouldn't it?

Here are some links to crimping pliers

There are some very cheap none insulated terminal crimping pliers at these websites that are very similar to those that I have used in the past and they lasted for a few thousand crimping actions

Thanks - I meant links to the connectors/terminals themselves My ratchet crimpers are the replaceable die type so I think the lack of success is the bits I'm crimping on.

[Penelope Stopit]

Ooops, wasn't even close

The last ones I bought came from China found at ebay and they have proven to be good, some cheap terminals are a touch brittle and sometimes break near the crimp if put under physical load

You've probably seen these https://www.autoelectricsupplies.co.uk/product_lis...

There's too many to choose from https://www.ebay.co.uk/sch/i.html?_from=R40&_n...

[donkmeister]

Excellent, I'll get some ordered! Thanks!

[Penelope Stopit]

Ok then

Have a happy crimping Xmas
