Crimping 24 Pin

post #1 of 6
Thread Starter 
I have a HX850 and while trying to sleeve it, I have broken a couple of the 24 pin ATX connectors. I have eventually gotten them back on, but it was a pain, and now 2 of the cables are shorter, enough so that they dont flow well with the other 21 cables. I am considering just replacing all 24 so they are the same length, but I find it very difficult to crimp these pins. I have this crimper from FrozenCPU:

Does anyone have any suggestions to make this easier? I can order pins cheap, but I dont want this to be a disaster.

Thanks.

Thanks.

to avoid confusion, do you mean you have broken some of the individual female pins, or the 24 pin connector itself? if the tabs on any of the pins are broken or the pin came off, replace it all together. just get some 18 AWG (or whatever your PSU is using) wire and recrimp both ends. if you broke any part of the 24 pin connector like the retaining portion of each socket, REPLACE it.

if you ever have to force pins in/out of that connector, something is going to break and the retaining qualities of the pin/connector will be compromised.

I broke 2 of the female pins. Trying to get them out, i flattened the square end of the female pin. I cut it off, put on a new one, and now they are shorter than the others. The problem is, I had a really difficult time getting the crimp right. The 2nd part either wouldn't crimp the bare wire nicely, or the 1st part wouldn't clamp the wire shielding nicely. I don't know that I can replace the wire because it goes inside the PSU. I was thinking of recrimping them all so I could make them all the same length, but since I am bad at crimping, I dont think thats a great plan.

are the issues with crimping due to the tool not doing the job, or just misalignment of the tool/pin? if it is a tool issue, get a better one. if it is an issue with your crimping skills, practice on some bare wire... spare pins are cheap.

recrimping the entire connector would not be too bad, IF it is that noticeable to have two wires shorter than the rest... but since I have built cables for work, the crimping does not worry me.

depending on where they are in the connector, a 90 degree bend in the cable management could negate they short length and no one would notice.

how do they connect inside the PSU? the best option would probably be to cut the wire to about half its length, and solder it to another wire with the connector on it... this way you dont have to dissconnect the wire inside the PSU and you can make it exactly the correct length. how are your soldering skills?

Unfortunately the same as my crimping skills. The tool has 2 spots for crimping, one larger than the other. I don't remember what each is labeled, and its not here with me. Are there any good guides on doing this?

my guess is the crimping die has two different slots for either different size connectors, or different wire gauges. each slot should have two separate grooves - one for the crimp on the bare wire, and one for the crimp on the shielded portion.

like i said before... practice on some spare wire before doing the real thing, but that time has passed. if the two short wires are really going to bug you, see if you can find someone to solder the wires for you... recrimping that entire 24 pin connector sounds like it could be a real challenge if you are unsure.

check this out, super easy. pick up a cheapy soldering iron and solder (most are flux filled) at home depot, and some heatshrink from an electronics store and PRACTICE first. this might be a little easier than betting you can get all 24 pins perfect.
