Standard Cigarette Style Plugs and Sockets

Or you could possibly add that dab of silicon & let it dry before inserting the plug. Then it would just tighten the fit rather than sticking the plug in.

You have to watch this type of plug.
Some of them have a fuse in them, you unscrew the tip to access the fuse (glass type)
This in itself is not the problem however in order to ensure the fuse maintains a good contact they are usually spring loaded, the spring itself is the problem as it is often made of steel and is a coil (as springs tend to be) and can acts as a bit of a resistor. I have had a few, not under particularly heavy loads, get quite hot and have identified the springs as the cause of the problem.

As usual some are made better than others. This Jaycar locking one looks OK.

I fly radio controlled aircraft and have recently started to migrate from methanol/nitro powered models to electric. The currents involved are significant and we use a type of connector called an XT60. It's rated at 60 amps but I regularly exceed that with my lager models (2 meter plus wingspans) and they work great. Very positive lock as they are designed to be used where vibrations are expected.

Cheap as chips about $1 each.
check them out

I have started using them in my car and they work very well, and are cheap as, never come lose and very large contact area.

Only problem is my accessories cant plug into anyone else's car but not a big issue as I have made adaptors for the rare occasion that the need arises.

I'm not reffering specifically to Johns one here Stephen and have not tested it.

I always recommend the Lion brand item which has 4 copper plated prongs on it for superior grip , and a flying lead, and unlike some all the prongs make electrical contact.

Why I did this followup was because I nearly had a fire in the car saturday night caused by one of those cheap plugs with a fuse in it, what happened was that a short ocurred right at the entry point between fuse end and centre pin - perhaps because the screw on fitting wasn't fully tight and allowed some play ?

I haven't fully inspected damage yet but it appears that current was not enough to blow any main fuse but enough to melt 10amp wires (perhaps due to stainless steels higher resistance.)

Now I don't use these cheap plugs for above reasons but in this case it was part of a mobile phone charger with that cig lighter type end and fuse.

The above caused a little stir as fumes from melting wire came out of centre console for some time and I was unsure it I had a fire for 2-3 minutes , not a lot of fun in the pitch black bush.

Sounds like you caught it just in time.
There really are some cheap and nasty versions of these plugs around. Sometimes the cheaper sockets can be just as bad.

Ditto. Eight sockets in all and the same as yours. We have never had one of these pop out.

We put a small cable tie round the cable and fix a small spring with it, the other spring attached to the outlet / mount.
This holds the plug in firm, yet can be removed easily.
Never had an issue in 33 years of using an Engle with a standard plug.
The CSR couldn't dislodge them!

Thanks for that option - as I indicated post I am after options for the standard plug socket arrangement not alternatives which others have listed.

Thanks
