Most reliable connector. semi 7 pin or RV blade ?

Agreed..

This one's nice too. $81 for the pair

The EZ Connector is on my list. Making a pigtail is a non-issue so that other vehicles can pull the TT. And, as anti-theft, it doesn't hurt to use non-standard.

Tnanks, BenK for the milspec idea. I know of an engineer recently asking this very question who may enjoy that idea for his Airstream.

If you guys really want reliability, low contact resistance, many cycles (big MTBF), etc

Then why not look at military stuff.

I've used or spec'd to use on my military designs. This one has a
screw on barrel, but they also come in quarter turn and even safety wire



They do NOT have any vibration on the contacts, so they will last forever (almost)
hermetically sealed and extremely low insertion and break-apart forces

Contacts look like this (female half shown and the male half just a
round nosed pin)



Signal level up to hundreds of amperes. More contact surface than the regular
blade or round types

Wiping action the whole length of those spiral female side wires and
can get 'make before break' or 'break before make' or signal or power
in any combo in the same connector...though $$$$

Can even find them in surplus stores and on line too

When the OEMs resorted to plastic intake manifolds on towing duty engines, many opined that the end of the world was near.

For anyone growing up turning screws on Rochesters, the thought of mere plastic taking the place of meaty looking castings from Vic Edelbrock was blasphemous.

Yet that plastic proved to be every bit as good at funneling air to eek more hp and tq than ever before derived from a given displacement, with a lower weight benefit. Dustin Hoffman was right. ('60's Music plays: "Hello Plastic my old friend.... I've come to talk to you again....)

So I take it you won't be flying on a B787 anytime soon?;)

Last time I flew in one, we took off but turned around and landed quick with fire trucks lining the runway. Must have been that plastic part breaking. lol

bigcity... the issue with the magnetic ezconnector (and I've seen them live in person, Mr. Truck himself showed them to me) is that fact that no one else will have them on their truck. Not your neighbor who can rescue you instead of a tow company. Not the tow company. Pretty much no one except the cool gadget loving few who are far, far between.

Part of the advice attempted to be imparted by a few responders on this thread is to stick with what is universally industry standard. This is part of emergency planning. Finding the most durable industry standard connector is a safer bet when things don't go as planned.

That ezconnector is very cool though. It snaps right in. The O rings are nice too. But it isn't standard. It is a superior Betamax, when the industry is all VHS.

MM49... 260 Brass? Ok. That is a detail that I didn't delve into. I will stand down. You've got me beat. :)

Hey thanks for the info guys.. Discussion is always good and food for thought. But I doubt I will buy another Hopkins. I guess if my hopkins lasts I might.. Oh, did I just admit I was going to use my plastic Hopkins connectors?
I worked out a temporary install without ruining my bumper. anyway

I guess I'm just oldschool even though I haven't retired..

Then again. The industry will flood the market with a new connector which "we all must have" and most of the 7 blade connectors will end up in the land fill like the 5 and 6 pins.
