Insulated crimp terminals
Does anyone have a recommendation for decent midrange-quality insulated crimp terminals in an assorted pack that can be ordered online?
With terminals I've found a lot of them lately have really hard insulation. They are horrible to use so looking for some that have a softer insulation. Looking at them physically you can usually tell as the hard ones have quite shiny insulation with a bit of gloss. Hard to tell online though.
In the past brand name automotive ones like Narva were reasonable, but lately I've had some of those that were also very hard too. I object to paying extra for a brand name and getting low end quality. Utilux are nice but I can't see an assorted box that I wouldn't have to donate both kidneys for...
Looking for something like this assortment but happy to pay a bit more for something I know is decent: https://www.ebay.com.au/itm/Electric...EAAOSwk5FUs7Gj

How about bare crimps and them heat shrink over them, much neater job.

You can get the softer shields but you need a different crimp tool. You feed the shield onto the wire first...then crimp your spade then slide shield down over
But these are slowly disappearing. I got my last lot online.
But as Micheal says I also use Cabac...but I had to pay for mine.lol

(Eskimo has picked up on the fact that I work for a sister company to CABAC )
Despite the fact that we get them for a better than retail price, the guys in the office who do amateur radio and other (non-work) electrical tasks do like them and use them. Apparently there is even a type that is basically a terminal with a heatshrink sleeve on it, so you crimp on and then shrink the sleeve down for a better fit.

Thanks guys. I've also used Cabac ones but had forgotten about them.
Dave J - I've got a few non-insulated terminals here and do exactly that if space is an issue or I really need a neat job. Most of the time though I just need a terminal on the wire and space isn't an issue so I don't want to be messing around with heat shrink and changing the crimp dies etc.

Just a word of warning if you’re using them on AC applications..
Check the rated voltage from the manufacturers data sheet.
The reputable ones will generally be rated at 600VAC, some of the less reputable brands vary somewhat from 600VAC to 30VDC.
We had a ‘thermal event’ at work about three months ago that did a lot of damage to an Epiroc Boomer rock drill that was traced back to the insulation on a control circuit lug breaking down with heat and coming into contact with another piece that slewed. When the packet of lugs came out of the cupboard they were found to be ‘automotive use’, not rated for the 400V circuit they were part of. They were also found to be crimped with a staking type tool, not a ratcheting form crimper.
Have a look at the Ashdown Ingrams website, they should have something.

I'm no sparky, but in my view its all about the quality of the connection for anything I touch. I won't have anything to do with those stupid "squash it like snake on the road" crimpers that come with cheap automotive crimp sets - any I've ended up with in my hand go straight in the bin.
I've even taken to using bootlace ferrules for the normal clamping type connections in plugs etc.
Anyway, soapbox aside....
Pretty sure Ashdowns terminals are just automotive use. I can't find an actual spec in their catalogue, and they won't let me register for online ordering unless I've got an ABN
There's a branch not far from me, I'm just trying to avoid going out in the current climate....
I've been happy with their gear though and I personally wouldn't have an issue using the terminals for anything I'm likely to encounter at home.

I love bootlace ferrules for electronics, but I'm not sure they are approved for the types of connectors you describe. Some mains connectors work on the principle that when the clamping surfaces bear down on the wires they squash them flat which increases the contact area. A bootlace ferrule could interfere with that process. I've seen circuit breakers where the instructions specifically prohibit twisting the wires so the individual strands of wire flatten out and maximise contact area.

Hi Guys,
Bootlace ferrules are required here in the UK for multi stranded wire terminations. The idea is that it prevents the strands getting splayed out and weakening the connection compromising the current carrying capacity. Soldered twisted strands are also banned for reasons previously discussed.
The note about voltage ratings for insulated push on connectors is important ! Just look at the number of Chinese DC motors that Have failed because the push on connectors have overheated and damaged the brush holders.Best Regards:

Now that's a great idea I can use on my current project, I have been looking for labeling and those professional labelers are expensive. On guy on eBay had a bunch of numbers all consecutive for sale, but this idea is better as you choose whatever.
On my Chinese mill and I think my lathe have white covers on the ends with texta markings hand drawn on them.
Printed numbers and letters would look so much more professional and wouldn't rub off, thanks heaps for the tip, something I should have thought of myself.Using Tapatalk
