Crimping a Molex part

R

Rileyesi

Guest
I am using a Molex connector (part number 43025-0200). This is a crimp type
fitting. They recommend a special crimp tool (part number 63811-2800) to crimp
the wire to the connector. The best price I've seen so far is $180 US.

I don't have to crimp alot of them, so I don't want to shell out the dough.

I'm hoping someone is familiar with this part and can tell me of a way to crimp
without the expensive tool or maybe a cheaper source for the tool.

Thanks.

: Nice connector! Easy to crimp parts. Sorry I don't have a
part number for you for the tool I use, but it is a universal
crimper, Pliers like, not compound, and I paid $5 for it a the
Electrical tools department. It works fine.... The removal tool
is another issue. Never found one...

Radio Shack Cat # 276-1595, $9.95, is a D-sub connector pin crimper.
The smaller of the two crimp positions should work. Be aware that you might
have to use a grinder to reduce the thickness of the tool on the side away from
the wire side so that you don't mash down the two tiny square tabs that are
between the crimp section and the barrel of the connector. The tabs must be
there and sticking up in order for the connector to fit the housing properly.

If you have problems, I could take a photo of the way my pair is
modified and send it to you.

P.S. The Micro-Fit series is an excellent choice for most uses.

Goto http://www.digi-key.com and get 63811-1000 for USD$38.

This is Molex's general-purpose low-volume crimp tool for open barrel
connectors, which is what you're using. I use it with Molex's KK
connectors with good results.

Using a general electrician's barrel crimper will NOT get you good
results - crimps will be deformed and will not insert / lock properly.
Been there; tried that; bought the right tool.

Looks like the one I bought for $5 at the electrical department.
Exactly!
And it works!

I don't know if any of you are aware of it, but the standard of the
shelf hardware store terminal crimpers are not the type for Molex pins.
The proped crimpers actually roll the wings around the wire and
insulation, not just crush them. Jameco Electronics sells the right type
for under $10. #99442 for 14-26 AWG wire ($8.95) and #159265 fo4
20-29AWG wire ($9.95). The quality isn't that of the >$100 Molex brand
crimpers, but I made over 1200 crimps last summer with only 4 failures.

Everyone I know is aware of the proper way to crimp a terminal.
The Crimper I have also rolls the crimp. The "Right type" is the
one that works!

I wasn't referring to the kind that crimp plastic covered
terminals.

Could very well be. There's not too much special about the tool, it's
just not common where I shop.

For readers who might not see the issue...

Around here, the electrical department in the hardware store sells
barrel-crimpers (the crimp tool has a "u" shaped opening), since all
anyone sells here for electrical is closed-barrel connectors. Those
tools fail most of the time on open-crimp connectors like the OP's.

The Molex tool (and apparently yours and the other poster's tool at
Jameco) has a slight peak like a "w" in the crimp opening. This rolls
the two "fingers" of the connector toward the middle of the crimp. It
sounds like you're fortunate enough to find these in the consumer
electrical department, where they're sure to be cheaper than Digi-Key
(which isn't hard to do, usually).

Cheers,
Richard

And our local store (a Fry's) carries Molex, Continental, and
several other connectors as well as cable for CAT5 and Coax.
