This makes it survive harsh vibration > 1million cycles at some f. I used to test this in some products and learnt how it is done. So often braided wire breaks due to lack of strain relief in consumer products poorly designed. | |

| Mar 10, 2019 at 17:08 | comment | added | D.A.S. | Our techs had NASA soldering manuals thicker than the bible and koran put together. imagine that. These included photos of idea pigtail solder joints for 10 lb pull tests on wires. But being hard brass, they still bend before breaking. THe wires soldered in PCB's have a discontinuity in stress/strain making them prone to vibration failures. ( do I need to explain that?) | |
| Mar 10, 2019 at 17:06 | comment | added | D.A.S. | Well that's a trade secret, but the cheaper ones are roll hardened CuZn (brass) then annealed or softened to make less brittle then tin plated. I have a retired friend who used to machine the gold connector threaded parts in large batches in the last decade for tidy profits for ARINC-B connectors that made these parts look massive. | |
| Mar 10, 2019 at 16:52 | comment | added | Hearth | Well now I'm curious how they managed to manufacture them so cheaply, as the shape looks like it has to be machined on a lathe... or are they cast in molds somehow? Those protrusions combined with the bottom part apparently being hollow makes them seem kind of complex to manufacture. | |
