Basic question about connectors

[shortbus=]

A valid electrical crimp connection needs the wire and connector at the crimp point put under sufficient pressure to cause them to extrude slightly, causing cold welds and driving out all traces of air at those weld points. That's the basis of a "gas tight" connection - it can never tarnish at the connection points.

The terminals I talked about earlier did this. Each terminal press had a force sensor under it, and if the force wasn't correct that wire was rejected. These small gauge wires were for the computer control wires. And since they had a long warranty on them they didn't want trouble "down the road".
