Crimping tool for PH 2.0mm connector
« on: September 01, 2019, 06:46:39 pm »
Hi,
what crimping tool should I buy on aliexpress to crimp PH2.0 pins: https://www.aliexpress.com/item/4000036823994.html

I found e.g. this: https://www.aliexpress.com/item/33011080440.html But I don't believe they can crimp PH2.0 and also classic dupont pins as dupont pins are much more longer.

Thanks. I will consider it. But to be honest, I use cheap chinese crimping tool like the one I posted for dupont pins and they work very well. At least for occasional crimping.

TNI-U TU-190-08. I use it for JST XH but it should also do PH2. Always get a ratchet crimper which crimps both the contact and insulation in one go. Crimping a connection needs to push the material beyond the cold flow to make a weld-like connection. I doubt the PA-9 can apply that much force. Also a ratchet crimper produces the same force every time.

There are small lies, big lies and then there is what is on the screen of your oscilloscope.

I have those PA-09's and while they work pretty well, I would rather have one that crimps the wire and the insulation in one operation. It would also be good not to have to squeeze the "ears" in before you start. Those three operations add up to a really slow process.

Does such a crimper exist?

This is exactly the tool I'm looking for but I don't understand, how it can crimp KF2510 and also PH2.0 pins. Please see the picture. KF2510 is much bigger...

I really doubt KF2510 will be useful to you...
Take a look at the different size of XH and PH2 terminals: http://www.engineer.jp/en/products/pa09_20applicatn_chart.html

If you closely you'll see it the crimper has two openings. One for small contacts and one for larger ones. Most crimpers support multiple sizes. However I think the KF2510 needs a different crimper than the PH2.

Just curious: what sizes are the apertures?
From reading the following comment: 
 
>Seems very well built.  I've been using it for the JST 2mm spaced PH series pins (455-1127-1-ND and 455-2148-1-ND).  They barely fit so you have to make sure you line it up right, but once you do it seems to make a great crimp every time.
 
It seems to me that the supposed compatibility with PH terminal is not so perfect!

I know, but I think it is more related to wire gauge than to the length of the pins crimped. I think PH2.0 needs much less wide jaws.

Well, I too had to try a few things before finding a good compromise, which was mentioned earlier.

The Engineer ones are really hard to do.  They mostly make a good job, but are a pain to use.  You have to leave the crimp on the backing metal strip to even stand a chance of stopping the crimp rotating due to the insulation grabbing lugs never being 100% straight.  Then you have to crimp it again in the next size up jaws - and you have to make sure that the wire size is correct so it doesn't get crimped too far.  Even then, I had some where the insulation lugs were incorrectly bent so the crimp wouldn't go in the plastic.

The final tool arrived today, the TU-190-08, which is the ratcheting type.  Still not perfect but does a good job and is simple to use.  What is needs is a small amount of thickness removing from the front or back face of the dies so it has a bit of wriggle room; without it you have to press the metal backing right up tight to the jaws so the part which grabs the pin in the header doesn't get mangled.  I'm going to try a few more before removing material though!

Compared to the Engineer ones, this wins for me

I have TU-190-08, don't recall any issues with mangling the pins unless I was way off. Could be a defect, jaw width on mine is 3.97-4.00mm. The really nice crimpers will have a spring loaded holder to locate the crimp, but then we are talking 10x the price.
No reason to get the Engineer pliers when these exist.
