Go total overkill with a Nordlock washer combo

[dklawson]

Ok, how about one all assembled, the OP could put a lock nut on the rear of this connection but loctite that on?  This would have zero effect on the conductivity of the of the connection would it not?

 

I still doubt that loctite in this situation would actually make the blindest bit of difference to the function unless as I previously stated it gets pasted all over the joint.

 

 

It is your car and you can do with it what you want.

 

I am only telling you what our practice in industry is and sharing what I have also done on low budget race cars.

Well today we sat down together in the office. Yep a a group or engineers. And this is what we decided on.



This will stop the terminal moving and therefore undoing the screw.

Thoughts.

Oh and I love the knowledge on this forum and the discussion it brings forward.

A few things I'd add to that combination;-

 

1) If I was going to run that way, I'd be inclind to fit a flat washer under the Screw head to reduce 'screwing up' of the face on the lug from the crew itself when tightening, and

 

2) It may have reduced current carry capacity due to most of the current on;y going through the tips of the star washer from the lug to the palm of the switch, though, granted, some will also go via the screw

 

3) It could well promote corrosion as it's open to breath and will have DC going though it. If the Crimp is copper and the terminal Brass, then I'm sure it will corrode (and that's been my experience).

 

What was 'the committee's' thoughts on a Screw / Star Washer / Crimp / Palm assembly?

 

Just some further thoughts, if you're looking for the most reliable connection, then I'd suggest considering soldering the wire direct to the switch.

That just locked the screw to the crimp. Crimp could still move against terminal.

Other option is just to route the wires so any pulling force is tightening only.

Corrosion is not really an issue in my head. Slowly degrading performance is also not really an issue. It is the failure in use that I want to be sure of. Not wanting an electric water pump to stop mid run. Or fuel pump either but not as much of an issue.

There is a blue paste / varnish that Airbus use on some connectors that are open to atmospheric conditions. It applied once the connection is made and this prevents any corrosion from occurring.

 

If you really wanted to then something of that ilk could be used.

We use a flat and a spring washer on all electrical connections on our trains. They've been in service for over 30 years using this format and seem to be doing fine.

[sledgehammer]

how about a dab of locktite on the exposed screw thread on the back of the connection

 

which isn't near the electrical path / connection ?
