replacing female molex pins

trenolds39 · 05-July-06, 02:38 AM

When I was sleeving my psu, a pin on one of the female molex was giving me a difficult time, and after messing with it for a considerable amount of time, I resorted to using brute force even though I knew it would end this way - I broke it. I've ordered plenty of replacement pins, but what is the most efficient way of removing the broken one, and attaching the new one?

Thanks

Molex Pin remover

Im sure you can find a better deal but thats what you need.

As for adding them im not sure about that.

Maybe I should specify:

I don't need to remove the molex pin from the connector, I need to remove it from the wire itself. Ive removed the wire crimp, but I can't find an easy way to remove the conductor crimp. A razor blade is the closest thing I can find to remove it, but it's not working too well. Is replacing it a simple matter of reversing the process?

Yeah that is a pain to remove, even factory crimps. To be honest the easiest way for me was to just put new ones on. If you don't have the pins, cut and solder the wire to fit is the other option.

You mean as in simply put a new molex pin over the broken one and crimp them together? I ordered a ton of gold plated pins, which I hope doesn't cause problems considering all the other molex pins are well...not gold. Thanks for the advice guys.

HAHA no, sorry I forget some people take advice to strict...

After you have cut the wires to length strip of the sheilding about a 1/4 of an inch and crimp on the new pin.

If you bought new pins, I would hope you get the crimping tool...even though pliers works to.

I do hope this is why you are pulling the pins.

them being gold won't matter.

trenolds39 · 08-July-06, 02:44 AM

So I just got my replacement pins today. But the old one hasn't come off yet. I'd rather not cut the wire off at the pin and make a new one. Not to be stubborn, but I want to beat this crimp! Here's a pic to specify what I'm trying to get off.

Thanks again

So I cut the wires to length, and crimped the pin on w/ pliers, which was, well...messy. Does it matter if some of the wire is sticking out of the crimps?

Also, for future reference, where can I get a molex pin crimping tool? Let's just say the job I did on this one didn't turn out so pretty, though I believe it will suffice, also it is one of the ground wires so it's probably safe. Lokie I can't see how you can fit those two cables into that crimp, unless you have some really fine needle-nose pliers. I only had normal pliers available at the time, so it was tough. Enough of my rambling, though.

Thanks a bunch for the advice guys!

It takes time to get it down with pliers, it is more of the ghetto way but it can be done. This is a molex crimping tool.

A little wire sticking out wont matter, unless its so long that the wire can stick out of the molex, basicly what is your definition of a little? After you do a couple you will see exactly what length you need and improve from there.

trenolds39 · 15-July-06, 01:51 AM

Oh, I stripped the wires to length, ect. But when I was attempting to crimp it, the strands kept coming out and going crazy, and after I thought I got it crimped right, the insulation crimp came undone and the whole friggin thing popped out. Yes, I ordered one of those from Frozencpu around 4 days ago, hasn't got here yet though. I couldn't really find one for "cheap", the D-sub crimps looked about the same, but I didn't want to buy one that would half-ass it, like I did

. Hopefully I can remove this last head without cutting the wires again, otherwise it will look ridiculous with two wires around an inch shorter than the others.

Thanks again for the help.

Lokie · 15-July-06, 01:56 AM

Worst case you can allways solder a longer strip of wire.

I would stop now and practice on spare wire....the stuff you cut off would be best.

cipher_nemo · 15-July-06, 12:37 PM

You might want to grab both an auto wire stripped and an electronics crimper that works with molex and ATX pins. Then, as Loki mentioned, practice first on scrap wire. I took a quick photo of these two tools I have so you have an idea of what they look like...

On another note, I ordered regular non-gold-plated molex pins from FrozenCPU and then shipped me gold-plated pins. They probably ran out of the regular ones, but their prices are high so they're still making a profit selling me the others. I got the gold for a little cheaper, even though it won't matter because PC devices all had aluminum or steel power plugs.

trenolds39 · 24-July-06, 06:11 PM

Well, after waiting a week to receive a molex pin remover instead of the crimper, I finally received what I originally ordered. It took me a couple of tries to figure out how the pin is oriented in the crimper (are you suprised?), but I finally got it, and it totally kicks ass.

Thanks a lot for the help guys
