CPC crimper

Bubblehead

Well Known Member
I am preparing to install some Tyco/AMP Circular Plastic Connectors in new wiring going into my -8. I don't want to spend the $s on a crimper though. Series 1 crimpers are about $200 and Series 2 crimpers are almost $300!

Does anyone have either series crimper they'd be willing to lend/rent for a couple of weeks while I get the panel wiring completed? I have only bought a couple of Series 1 CPC components so far but could return those for Series 2 if that is the crimper you have.

Here's a picture of the connector I am talking about.

John,

As you may already be aware, the Series 1 CPCs use either a Type III "open" barrel contact or a Type II "closed" barrel contact. If you use the open style, this open barrel crimper works just fine: http://www.mactools.com/Product/tabid/120/productid/320357/variantid/311116/Default.aspx. Some people will tell you otherwise, but I've used them for 15+ years without a single issue and I'd stake my A&P license on them.

If you choose to use the Type II contacts (which I used exclusively on my RV-8), pick up an AF8 (also M22520/1-01) crimper off ebay or any number of other sources. You can find them cheap and work on all the Type II contacts, size 14 thru 24.

If you use the Series 2 CPCs, I recommend ONLY using the DM-20 "closed" barrel contacts. Those will require an AFM8 (also M22520/2-01) crimper, also available in a number of online places.
 
Jeff - excellent information. I did not realize the difference between Type III and Type II pins and sockets. The specific information on the crimpers is exactly what I was looking for.

Right now I have a couple of Series 1 connectors with Type III pins and sockets so will look for the Mac crimper and give them a try.

Aerhed and Jeff - Thanks for the info.
 
If you need any help....

John,

I live in Lewisville and work out at Fort Worth Meacham. If you run into any issues, I'd be happy to stop by and lend a hand....I've done a fair amount of wiring over the years. :D

Let me know.....
 
Jeff - It would be very helpful to just have you crimp a couple of the Series 2 pins. I'll pm you to arrange it. I'd like to understand Type III vs Type II contacts better too although I have looked at the pages in the Allied Electronics catalog.
 
Sent you an e-mail John.

FYI and for others who may have the same question:

As far as the Series 1 Type II and Type III contacts go, it really comes down to cost and availability. I think for most of the applications on our airplanes, either will do just fine. Both have the same current rating and can be used in most of the same Series 1 plugs.

The Type III contacts are cheaper and give you the option of Tin or Gold plating, where as the Type II only come with gold plating. I prefer the Type II only because it gets a better (in my opinion) crimp using the AF8 crimper, just like standard Mil-Spec M39029 contacts.

You can find all the CPC and contact information you'd ever want to know right here: http://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Catalog+Section%7F82021_CPC_sections1-5%7F0807%7Fpdf%7FEnglish%7FENG_CS_82021_CPC_sections1-5_0807.pdf%7F206150-1

But that may make some peoples heads start spinning. I recommend for most of our simple applications, just stick with the info you can find in the Allied Catalog and you'll be fine: https://www.alliedelec.com/catalog/pf.aspx?FN=202.pdf

Jeff,

great info... just one thing I'm missing. I can't figure out what MS number those type II machined pins are. I'm guessing they're not a M39029 variant, and the allied catalog shows them as having a red and a yellow stripe, with a machined away section in between.

I guess what I'm really asking is, what turret or positioner do the type II pins require on the AF8 frame? Does the MS22520/1-02 turret do them, or is it a different one?
 
Ian,

To my knowledge, the Series 1 Type II contacts do not have a mil-spec number.

AF8 turret heads TH501 and TH502 should cover all of the contacts you might use.

https://www.dmctools.com/assets/TH502_env.pdf

For what it's worth, I can tell you that the teeth of the AF8 crimper fit perfectly into the "machined section" (the area between the insulation support and the inspection hole) of the Type II contacts, so no additional positioning is required. For the few contacts that do not have the insulation support, it is very easy to eye-ball when you have the AF8 teeth centered on the contact barrel. I've crimped hundreds, possibly thousands, of the Type II contacts with this method, with no problems at all. The turret heads are nice, but not absolutely necessary.
 
I use a lot of pins with CPC series 1 connectors. The pins that we are using right now are from Conec Male Pin P/N - 161A18299X, Female Socket P/N - 162A18709X, 20 - 24 AWG.

Looks like the crimping tool have been covered pretty well.
