It will pull right out. --- End quote --- 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. |

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. |

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... |
