Help Identifying ribbon cable and connector type?

Ah yes I forgot there needs to be 8 pins so that would indeed be 8 of the crimp connectors on each male side.

So I'm basically out of luck when it comes to the tool? I have to buy their $1,500 crimp tool and there's no alternate?

CPC connectors look like such a nightmare. If this was just standard ribbon cable with the usual type of connector I have a feeling it would be 1000x less painful.

Glad to hear I'm getting somewhere lol.
 
The Hozan crimp too will work, but 16 crimps by hand might not work for 1000 pcs. It would work for 10.

Get yourself a caliper: https://www.amazon.com/Electronic-Measuring-Millimeter-Conversion-Micrometer/dp/B0793MN9KB

I bought that one for far more money. A few batteries could cost you that. Only the LR44's work for me. I did have to put a piece of Kapton tape on the battery door to increase friction.

My favorite source for CR2032 ans LR44's is http://www.infinitelights.com/. Free shipping is easy to obtain.

You still have to determine the wire gauge and Insulation thickness of the cable in question.

Could you please link to the Hozan crimp you're mentioning?

As for the volume, we'd be making sets of 4 full cables so that's 64 crimps per set of 4 cables.

The wire size we'd be looking at for the ribbon cable is 28 AWG.

I might have access to caliper but unfortunately I wont be able to visit the cable until Thursday and would like to have a game plan by the time I get there.

So far the biggest issue is that crimp tool, TE wants me to buy their super expensive one but if you could link to a Hozan crimp that would be a huge help.

I did link here: https://www.hozan.co.jp/E/catalog/Crimpers/P-707.html for the tool specs/

Then this https://lmgtfy.com/?q=Hozan+p-707 works to find the tool.

Amazon has it for ~$80.00

The auction site has it too for about the same price.

Then these https://www.easternbeaver.com/Main/Elec__Products/Tools/tools.html guys have it for $70.00 USD ppd.

This (696202-1) https://www.alliedelec.com/product/te-connectivity/696202-1/70089923/ is basically what I have. Mine has the AMP brand label and has red handles. What I have notices is that sellers have the wrong picture.

The P-707 closely matches the AMP crimp tool that I have. It generally gets pretty good reviews.

Thanks for the link.

What confuses me as someone who has zero experience with anything past a simple RJ45 connector is how different the TE 734870-2 Crimp Tool looks when compared to the Hozan P-707

This is their tool

https://www.te.com/commerce/Documen...BpdfEnglishENG_SS_411-18413_B.pdf734870-2

https://www.te.com/commerce/Documen...2ApdfGermanGER_CD_734870-2_A.pdf734870-2

And then the P-707 https://www.hozan.co.jp/E/catalog/Crimpers/P-707.html

To the untrained eye (Me) it would appear those are two different types of crimping tools?
 
If you look at the Hozan link, you will see the pics of the wire crimp and the insulation crimp. For every terminal, there will be two hand cripms with different dies.

There are only two insulation crimp dies on the Hozan tool.

The wire crimp "folds" over the tabs.

One is a production tool and the other a service tool. The production tool will be faster and will generally be ratcheting and supply a specific force. It supplies the terminal from the reel and crimps both the insulation and wire at the same time.

ith a service tool, you have to juggle the wire and the terminal and the crimper at the same time. You might insert the terminal into the crimper, then the wire and then crimp say the insulation. Now take it out and crimp the wire using the rounded die.

With larger terminals and wire, you can generally insert the terminal on the wire and then crimp. You don't need 3 hands.

Inspect and test each terminal crimped. Pull on the wire while holding the terminal after making the crimps.

Here is a video explaining the process.

I was looking at another video where the crimping tool would "click", the first tooth on the ratchet mechanism. This would be enough to hold the terminal in the tool. You then insert the wire and go through the rest of the ratchet. It releases automatically at a particular jaw height, thus insuring a "better" crimp that is less operator dependent.
 
If you want, you can drop a couple of single wires and some terminals in an envelope and mail them to me. I would crimp them using my AMP tool and mail the results back. I'm on the East Coast, US.

Thank you so very much for the video that really does clear things up quite a bit. I was having a hard time trying to picture in my head how this crimp tool works especially since the connectors are very small and I haven't worked with multi pin connectors like this before. My knowledge is pretty limited with electronics and I haven't done much more than swapping parts like already pre-made ribbon cables and such

I think it was especially the folding the tabs over that confused me the most.

Thank you for the offer I'm on the west coast. Would you happen to have an email? or is there a PM system on this site?

I'm going to purpose that my friend and I go head and purchase the connectors and the Hozan crimp tool plus a length of ribbon cable and make some test cables as a proof of concept.
 
PM's are called "Conversations". If you click on someone's handle there will be an option to :Start a Conversation"

New members might be restricted to be able to send PM's immediately. I sent you a PM. replying would bypass any restriction that is in place.

Ribbon cables are usually terminated with IDC (Insulation Displacement Contacts) similar to RJ45's. D series and rectangular connectors are available. The IDC connectors don't like to carry appreciable current.

I first dealt with crimped connectors with DEC computers. See http://avitech.com.au/?page_id=1628 and Berg Connectors.
