12 vdc plug
« on: August 29, 2021, 06:28:21 AM »

I'm going to add at least one more 12 vdc plug in my cabin.  One is going to be for my Engle freezer.  I don't really like the cigarette lighter plugs.  In the common wisdom of the group what is the best 12 vdc plug?  Doesn't need to be waterproof just something that handles the load and stays plugged in well.

anderson power-poles are pretty common in the ham radio world.  though, since it's inside, i'd image you could use just about anything reasonable

Jim : Look at the Marinco and Anchor brand cigarette lighter style plugs.  They are not the cheap flimsy plugs that you usually find in marina stores!!

The lighter plug/sockets that Rom refer to are actual locking.  1/2 turn to unlock them. Iíve used those for all the 12v receptacles aboard.   But you must use the matching plug and socket for them to lock together.

Are you looking for a panel-mount mount socket or a cord-end socket?

You could use a 2-pole polarized 12v, which you can also get with a flush socket.  They donít particularly lock in though.

When I need a locking set, I use a NEMA L1-15 configuration. Itís ďtechnicallyĒ not for 12v, (the NEMA configuration is a 120v mini plug/socket) but they work great for the purpose.  They lock with a slight twist (like a shore power cord.). Iíve also gotten receptacles in a flush panel mount type.

Ken,
I'm looking at both.  Panel-mount to be mounted possibly near the battery selector switch.  Cord-end to splice on existing cigarette plug to allow me to plug the fridge into other places.
That way don't need to buy the pricey cord from Engle.

Well any of the type plugs/sockets I mention would work and also have flush-mount sockets available as well as cord-end plugs and sockets. 

Of course, if you use an oddball plug, the socket is then dedicated to that use unless you make a pigtail adapter to a standard cigarette-lighter socket that you can plug in something "standard."

The NEMA L1-15 plugs are about the diameter of a quarter (below is a 3 pole (center ground) -- you obviously need only a 2 pole (same dimensions.) 

Another option smaller option is an 2-pole Amphenol type connector (last 2 pics) - about the diameter of a nickle.  Their cases screw together nicely and are weathertight (I don't have a pic of the female half, it's 700 miles away right now.)

It really just depends on how secure you want it - push together like the 12v, 2-pole (trailer type) plug/socket, or a twist-lock or screw-together.

I did go with a decent (sturdy) cigarette plug for our Engle and just put it in a protected area where it wouldn't get knocked. The good thing about staying with this is we can easily move the Engle to the car or ? and not have to mess with the 12v plug.

Jim : I'd stick with the cigarette lighter style plug - I just wouldn't go for the El Cheapo brand!!!
