12 Volt plugs

gosstyla · 12-04-2007, 16:28

Anyone know of a plug that screws in or securely fastens in some other way.

I'm continually melting plugs and throwing breakers using laptops because the plugs and sockets won't maintain good contact.

Marinco (AFI) pricey devils, but they work well! Buy the combo pack that gives ya both the plug & the receptacle.

1/4" Audio jacks. I wired my boat with these and they've worked great for, Oh lord 15 years! You have to buy the good ones though. Switchcraft is what I used. Radio Shack plugs worked about a week.

When attaching one to a gizmo, solder the leads, Positive to tip negitive to the case. Fill the plug with silicon and screw it togather.

I totally love these for 12V.

I’ve never been happy with the normally available 12VDC outlets (receptacles) - not the W.P. Bi-Pin Deck Connections (Perko1189 Series, Cole-HerseyM121-BP, SeaFit, & etc), and especially not the Lighter Socket type (commonly fitted to accessories).

For 12 Volt DC accessories, I use “Midget Twist-Lock Devices” (2 Pole, 2 Wire, Polarized, NEMA Code ML-1), such as the:

Hubbell #HBL7526C Flanged Receptacle (or Cooper #7468 etc.)
http://www.hubbellcatalog.com/wiring...s/Page-B03.pdf
and
Hubbell #HBL7545C Plug (male cord cap) (or Cooper #7467 etc.)
and
Hubbell # #HBL7506C Female Cord Cap (or Cooper #7464N etc.) to make an extension cord.

Although these devices are intended for AC use (UL rated for 15A 125VAC - polarized), they are an excellent alternative to the conventional DC outlets.
They are rugged, corrosion resistant, easily installed, attractive, and best of all “Twist-Lock”.

Not normally available at Marine stores, these NEMA type "ML-1" Midget devices are available at any good Electrical (or Industrial) Distribution Supply house. Electrical distributers can be found by "Locate Distributers" on the Hubbell website at: Hubbell Wiring Device-Kellems

I haven’t used the "Trolling Motor" connectors (Marinco #20188R), which though 4-pole, are "Twistlok".

Gord - they are also available at my local Home Depot - decent price and they work well - I do use shrink wrap where the wire enters the connector as well
