Tool for Crimping Pliers Dupont

Post by Dirk.B »

Hello

(Translated with deepl because my English is terrible)
OS: Windows 10 (10.0)
Word size of FreeCAD: 64-bit
Version: 0.20.26761 (Git)
Build type: Release
Python version: 3.8.12
Qt version: 5.12.9
Coin version: 4.0.0
OCC version: 7.5.3
Locale: German/Germany (de_DE)


Some time ago I bought a crimping tool for Dupont connectors. Connecting the plugs to the cable turned out to be much harder than I thought! Since I do not have three hands to hold the cable, plug and pliers, I have drawn a pliers shoe in Freecad and 3D printed.

Procedure:
Body 1
Pliers and insert scanned.
Images scaled via Image WB.
Insert redrawn.

Aah, now I see what it is good for; more predictable where it will finally be crimped. Nice idea.

Hi

very good idea why don't you patent

Maybe you need a special feature, go into Macros_recipes and Code_snippets, Topological_data_scripting. My macros on Gist.github here complete macros Wiki and forum.

Isn't the last part of the metal crimp connector supposed to crimp on the insulation?

Hallo Freedmann

Yes, of course you are right! Also the strands of the cable must not protrude as far as on the photo.it was just a bit difficult to hold the camera and the cable at the same time.

This is how it would be right

I have used that kind of tool many times and you are so right about needing three hands. The mfg. tried to improve the tools with a spring clip to hold the contact but that just gets in the way so you can't see what your doing. That's a good idea. I wonder if a jog in the track would make a difference in how well the wire is held with different insulation thickness for instance.

The video shows the trick, how it should be done without Dirk's helper, but it needs crimping pliers with a decent ratching mechanism, so that the clip can be slightly grabbed before inserting the wire.
