I had a friend ask for this recently, and my favorite places don’t seem to have it.

This is the connector that comes up from the truck into the chassis for many Aristo diesels, the pins are 0.1" on center.

Anyone found a source (most likely with wires already attached)

Greg,

Try www.molex.com. It may take some digging but I would bet they have the connector.

Bob C.

Have you tried Navin?

I think Molex 50-37-5043 https://www.molex.com/molex/products/datasheet.jsp?part=active/0050375043_CRIMP_HOUSINGS.xml

Right on Dan thanks! (and Bob).

Looks like you can’t find them with wires, I guess I better order some samples (free), and the crimp terminals (free) and find the right crimp tool ($$).

If I can put this together, then we can have some spares… cheep

Greg

I’ll have to get some, because I’ve fried one or two.

Gentlemen - There are a number of connectors described on my web page here

http://www.trainelectronics.com/Articles/Connectors/index.htm

that can be used to mate with what Greg has - I would recommend getting the female multi-conductor ones and using long double male headers to connect them — like these

https://www.amazon.com/40-pin-Headers-2-54mm-Length-Centered/dp/B077N29TP5/ref=sr_1_2?ie=UTF8&qid=1527521254&sr=8-2&keywords=0.1+header+long&dpID=41V249gZL3L&preST=SY300_QL70&dpSrc=srch

You can also use the shorter male headers and solder to the short end - put heat shrink on the wires and you have a nice connector

Hope that makes sense

Thanks Dave, but none of those are the right ones, same pin spacing, but not the same notches, and not the same connector. This is not the JST XS series as you show, but a Molex design.

The socket on the Aristo board has the ribs that match the “notches” in the picture above. Sure I could force it, but I can get the real thing.

I’m sure I will wind up with a lifetime supply of the crimp on pins. (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-laughing.gif), they are usually a bag of 100.

I have this on my site, as soon as I order the pins I’ll put that part number up too:

Greg,

Not sure how you will calculate cheap. Here is a link to the crimp tool on DigiKey https://www.digikey.com/products/en/tools/crimpers-applicators-presses/228?k=63828-1900.

If I read this correct, this is the correct socket https://www.molex.com/molex/products/datasheet.jsp?part=active/0008701039_CRIMP_TERMINALS.xml. And here is the Molex page for the crimp tool https://www.molex.com/molex/products/datasheet.jsp?part=active/0638281900_APPLICATION_TOOLIN.xml&part=active/0008701040_CRIMP_TERMINALS.xml. Based on the DigiKey pricing it might take a while to amortize that cost.

When I go back to work tomorrow I will check and see if we have the tool at the office. If we do, I might be able to work out something to get some pigtails made up.

Good luck Greg.

Yep that’s the reasons behind what I said earlier:

“Looks like you can’t find them with wires, I guess I better order some samples (free), and the crimp terminals (free) and find the right crimp tool ($$).”

But we do hardware, so might have the tool already. Looks like it works for a large number of terminals. We have an entire drawer in a big rollaway in the lab that is just these specialize crimping tools, and my lead h/w engineer uses mostly molex.

Bob, you have hardware stuff at work too? That’s great. Let me know, would want to make up a few, just to have, besides for my friend.

Anyway, will know this week…

Dang, they’re really proud of that tool, aren’t they? (https://largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-surprised.gif)

I’ve seen them for close to $1,000 each for really specialized ones, that have like 4 “die” converging… and we aren’t even at mil spec yet!

I’m making a product that will eventually have a manufacturing cost of $70, but the prototype boards and the low component quantities make the boards 2 to 4 thousand each right now… these tools are made to last years, as opposed to, for example, the plastic telephone connector crimpers you see at Home Despot.

Greg

I’m quite certain these pins can be crimped with a $10 generic crimper with little or no modification. Heck, In a pinch (<pun) I’ve crimped a connector with lineman’s pliers and a BB. However, now I question why would you want to replace with same connector if it burned out? Are you upgrading the wire Gauge in the new connectors? What does the board-side male connector look like?

Solder the wire & pin together !

Just crimp them with a generac crimped or roll in the ears with tiny needle nose. Just make sure they are holding on to the wire and closed in enough so pin can be inserted into the connector body.

But before you insert it “solder“ the wire & pin together ! And spend the money Trains

I have done just that for years on AMP (Now Tyco Electronics) Modu series connector pins, one just needs to be careful with the amount of solder used, too much and you will have fit issues in the housing.

Yea, and some folks just love to blob on the solder. (http://largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-undecided.gif)

Thanks for all the suggestions guys, I do indeed know how to try to get around the specific crimper, but in the long run, it still does take more time and does not give you as good a result. I’ve been doing this stuff for quite a while, especially when I was a poor kid, and a poor student. I know the suggestions are all meant to be helpful, but we will use the proper crimp tool. Thanks for the money saving suggestions, I know they are well-intentioned.

Dan, I don’t know Steve’s situation, but:

1. I want spares to fit the sockets on Aristo boards as stated.

2. I never stated I burned them up but more to the point, damaging a connector does not necessarily imply it was not up to the task.

3. why re-work a board that has the mating connector already?

So, I want a few spares in case I’m fitting a new motor block or just want to connect into an existing board without changing the connector. I like spares, so when something goes wrong I have the parts on hand. I don’t have a ton of Aristo diesels (since I run the transition era and Santa Fe), but I do have 12 spare 3 axle motor blocks and 12 spare 2 axle motor blocks.

Anyway, I have my answer to the source of the connectors, and between Bob and I we will make some spares. I will send a couple to my friend, and keep a few for myself.

Steve, I assume you would like a couple?

Greg

Yes, I would love to have a couple. Thanks.

It may take a while, I meant to order the components today. I won’t forget Steve. I’ll see if I can get the same colors as the stock Aristo

Greg

Parts received, will double check the fit…
