"No-crimp" connector idea
<< < (5/9) > >>
Zero999:
What voltage is this connector going to be working at?

If it can be plugged or unplugged, when live, then the earth connection needs to made first and broken last and there shall be no chance of the earth becoming live.

Going from the drawings in the original post,  there's no way it'll meet the above requirements.
Simon:
It also relies on a specific wire size to work. i like the idea but in all my experionce of using various connectors i can't see it working.

Tell that to a TRS phone jack.  >:D

Simon:
It's about the voltage level and safety regulations on mains plugs. Plenty of connectors are rated for high voltages and disconnect everything at once. My issue with this design is that in practice it will never work because of real life and contact resistance of the wire with the contact.

If you want a universal connector that is not a pain in the as use Deutsch/TE DT, DTM or DTP connectors and/or the equivalents from Amphenol sine AT, ATM and ATP. The crimp tool for all 3 sizes of pin and all wire sizes costs £500 and lasts forever. Never mind all of the other shitty TE connectors that have a single die for a single size that costs £500.
mikerj:
It seems extremely unlikely this will achieve a reliable gas tight connection.  Also what mechanically retains the cable, looks like one good pull would see the cable separated for the connector.
