Howdy,



I've got to crimp about 30 machined high density d-sub pins on an ACU 

install and I don't think my standard density crimper (B&C) is gonna 

work. I'd hate to spend $800 on a Daniels and postitioners for one 

little deed. Any ideas?



I thought about getting a $30 crimper and some of the fold over pins. 

Are those pins as reliable as the machined ones? Will the crimper (fold 

over style, also B&C) do those little pins in one of it's slots?



Pax,

My UMA instruments came with the overfold sub D pins. Crimps looked good and they have worked fine for a long time.

If you crimp connectors without the specific dies, you would

be well served by soldering the wire strands to the crimps as 

well or the wires might just fall out!

I have an AMP ProCrimp II with all the dies for the CPC

Series I connectors, and they still sometimes fail the tug test when I

don't oversolder them!

If you have the standard density crimper (the red one that puts the 4 

little indents into the pin), you can use it on the high density 

machined pins if you're careful.  What I did was cut a short piece of 

wire (like 1/8" or so) and put it into the hole first as a spacer to 

position the pin in the right spot.  Then you can crimp like normal.  

You may have to play around a bit to adjust the length of the spacer to 

get the pin in the right spot.  If you're only doing a few pins you 

shouldn't have any issues.  Mine passed a 15lb pull test and that's good 

enough for me.

Hmmmm, I was worried about the diameter difference and hadn't addressed 

the depth. You're saying that the red handle crimper worked on the 

skinny pins. I haven't counted the pins that came with the install kit, 

but I'd be surprised if there are extras to burn so I've been a little 

leery of trying tests.

I bought some from Mouser, so I had some to practice on.  If they have 

the little hole in them then you could also put some solder in there and 

that would probably work as well.  If you don't have any extras, I'd be 

leery of trying the crimper as well, because it took me a few tries to 

find the right depth.

   Your talking about the open-barrel, sheet metal pins.

   I just went to the shop and pulled three 24AWG wires

   from pins installed with my generic open-barrel crimp

   tool. I got pullout forces that ran from 8 to 11 pounds.

   If your pulling these off with your fingers you may have

   the wrong tool or are not closing it hard enough.



   I put some high density machined pins on with the $low$

   d-sub crimp tool and produced crimps that I could not

   pull off with the fingers. I don't have any of these

   pins on hand right now but as soon as I can, I'll do

   a calibrated pull-test and look at the cross sectioned

   wire grips under the microscope. But I'm betting that

   we'll find the crimps to be satisfactory on the HD

   pins too.

    Your risks for process error are lower with the machined

    pins. I thick Steinair can sell you some. I also believe

    the 20AWG crimper from B&C will properly install the

    22AWG pins. I'll see if I can get a considered confirmation

    in the next few days. I have come connectors on order with

    my favorite local connector guy but he's a 15 mile drive from

    here. When my order comes in, I'll pick up some 22AWG HD

    pins for the experiment.

Hi Bob,



I was responding to Ed's comment that he might get some stamped

pins.  I still think soldering crimped open barrels is the way to go.

The reason is that to meet specs on the pull test you must have 

a connector pin specific to both the wire size and insulation along with 

accompanying crimp dies. Since available wire may have unpredictable

insulation thickness in a homebuilder's shop, soldering is just extra assurance.

Thanks Bob,



I'm interested in how the experiment comes out.
