Title: For those looking for JPT connectors
Post by: Tony Smith on July 14, 2019, 03:04:42 AM
I bought these from Aliexpress, they have arrived and I am satisfied that they will work and are of reasonable quality.

They look to be the same as the ones that I sourced through EME, except that the little insulators are blue rather than red.

I can’t quite see the rubber boot in that photo, but the 3 seperate cable outlets at the back of the connector, look to run side by side rather than in the one double insulated cable which might mean being a little creative with heat shrink and insulation tape to keep the outlet of the boot looking pretty and water tight.

I should have tried to recycle the original single outlet rubber boot but I wasn’t sure if it would fit over the actual connector or not, but I think with a bit of gentle heat and massaging, it might make it and the replacement would be virtually undetectable then.

There should be nearly enough connector sets in that bag to just about cover your fleet Tony?

Adrian, you do realize that you now have 10 pairs of plug/sockets coming don't you?

I thought I had a lifetime supply laid in, but you got me beat.

Yeah well, I have a few spare sets now. But not as many as Adrian will have......

NOTE!

No boot included. I didn't care because I have large diameter shrink tube, a heat gun and I'm not afreaid to use it :-)

Haha. My heat gun is one of my favourite tools these days. They’re very versatile.

Although those connectors are meant to be crimped, (as were the original factory connectors on mine) I think that you might actually need the correct fancy assed crimping tool that bends the two wings over and presses the whole lot down together. I don’t think a dirty old garden variety crimp tool will do it properly? I soldered mine to avoid the complications.

They are cheap enough
I ordered them
Good to have
I have been using Molex connectors but this will make  everything compatible

I use these to crimp this kind of connector
They are not perfect but work well with a little practice

Be careful soldering this type of connector
If the solder wicks to far into the wire you can cause a stress point in the wire that  can  brake  from  vibration

Hi Tony - yep I'm a belts & braces type who always buys too much lol lol lol
.
They'll be useful for future electrical connections - no doubt I'll be buying more stuff over time [ch128076][ch128522][ch128521]
.
I too have a variety of heat Shrink tubing too [ch128513]

Yep, thanks for that MrC. That is the sort of crimper that I was referring to.

I take your point re the stress point in that wire and if it is going to fail, it would no doubt do it smack, bang in the middle of nowhere and it would be nearly impossible to trace!

I actually inspected the original connectors and I couldn’t for the life of me figure why they were crimped rather than soldered, but that explanation makes perfect sense.

I might track me down one of those crimping tools I think and then hit on Tony or Adrian for a new connector set!

The horror of trying to track that fault down in the middle of nowhere sends shivers up my spine.....

My mechanical ‘Guru’ dropped over today, (he’s my old boss, but a good mate who has been mentoring me for over 25 years) and we were discussing another entirely different issue on my coffee roaster and he coincidently, made exactly the same comment that
MrC made regarding introducing a stress point in conductors by overheating a soldered joint! I think that the Universe is trying to tell me something....

Received my order today
They appear to be of good quality and are compatible with the OEM connectors

Will those Meterk style crimpers that you posted above work ok on that connector MrC?

I don't know about that specific tool but these connectors usually require an "open barrel" die.  Sometimes called an "F" (not to be confused with "F Type" which is some kind of co-ax connection).

The other thing to make sure of (if MrClubike can't give you the specifics) is that the one you get will do the right size wire your using.  The bean can wiring gauge is pretty small and I've seen that some of the crimpers will stop at the next thicker gauge.
