The insulated spade connectors are total cr*p and will not hold a cable no matter how you press/crimp it. It will pull right out.

Time to go full autistic and do unofficial pull-out force test:



1,5mm^2 multi-stranded copper cable, inexpensive crimp tool from local auto store https://www.biltema.fi/tyokalut/kasityokalut/pihdit/liitinpihdit/kaapelikenkapihdit-2000037081  (Sorry, no German Klauke crimpers or terminals in my price range)

First connector: inexpensive PVC? insulated blue sleeve ring terminal from local junk store, marked K.S. so probably this one: http://www.ksterminals.com.tw/eng_products_list.asp?P=1&FKindNO=F04&SKindNO=S03
(non-brazed, non-dual sleeve)

pull out force: 79 lbs , wire breaks before pulling out

Second exemplar: red Nylon insulated female spade connector, no markings/brand but this is probably also K.S or (Swedish Abiko as they are very common around here):
(double copper/brass sleeve construction)

pull out force: 68 lbs, wire pulls out with couple of broken strands left in the connector.

Both results exceed UL - 486 A, UL - 486 C - UL - 310, MIL-T-7928,  and MIL-DTL-22520G Military Class 2- Military Approved Terminals pull-out force requirements.

I love when people get their tools and do some tests :-+

I've used those insulated crimp terminals to support a lamp in my workshop, as that was what i have at hand. The first three pulled out, they were from a cheap assortment box. Tried with a Duraseal, it is near impossible to pull out. All were crimped with a Knipex ratcheting crimper. There must be some quality differences between them.

They do actually support some weight, see attached photo.

They are not all definitely equal. For the sake of completeness I dig out some crappy blade connectors that I haven't used because they seemed to come off easily.

Red female spade from unnamed assortement box that I bought 20 years ago: 22lbs
red female spade K.S. brand: 51lbs
(previously tested dual-sleeve Abiko 68lbs)

mzzj, that lines up with my experience, which is why I swore off the isolated types and opted for the non-isolated with the proper crimp tool.
Apparently you CAN get quality isolated connectors. Problem is only, that if you go to the DIY store, you only get the crappy types.

I accept your experiment, but will stay with the non-isolated, having spent money on the tools.

Seem to be luck of draw what you get from DIY stores.
All of my connectors are from DIY stores but lately I have bought only the better looking ones (thick metal sleeves or dual metal sleeve) Pretty sure you can get also crappy uninsulated ones for that matter...
