Has anyone made the plugs & sockets for a 12 v car cigarette lighter socket extension on their machinery at home
I have this perennial problem in that when the trailer home ( caravan ) is connected to the car I can't use the cigarette lighter socket to plug in the 12 v tyre inflator as the cables are too short . same happens when I park up i can't reach the other side with out driving the car tot he other side and when this is parked up at home it means a lot of messing around .
I'm after making a quality.. last for ever ... heavy duty portable extension that can me kept in a plastic carrier bag or one that I can wind up on a small cable reel that's no bigger than 7 " in diameter.
Non of the commercial ones that are supposed to be heavy duty that I've seen in the last 40 odd years have eve been much use... far too flimsy all suffer from the arced up contact faces and if there is a brass sleeve /connection surface or two it's not long before they go greasy & high resistance as it starts to oxidize .
Simple same size wire extension cables purchased from the auto goods shops are rarely satisfactory as the volts drop is too much to run the newer high rate tyre inflators .
Cutting off about 8 inches from the plug & socket then extending the cables with a heavier pair of wires soldered in place and then taken back down the original cable at the end again still causes a big enough volts drop over the 24 feet of extension I've made made today .
At the points of contact in the plug & socket connections . The wiped neutral contact area ends up with about 1. 0 mm sq making contact and after a few uses this gets arched and becomes high resistance. The live center contact seem to have even less contact , it also has a great tendency to ease itself free of metal to metal contact to the central contact , this also makes a tiny arc and a high resistance after a few uses.
Has anyone developed /made any solutions , other than using /making a simple heavy duty block with a heavy two pin fused socket to put in the car and making up a 24 foot heavy gauge electrical wire ( 4 to 5 mm dia ) extension in the same plug ends & female socket and putting a new heavy duty two pin plug on the tyre inflator cable as well ?
