Does anyone know what this connector style is called?
Bonus if you know where to get them :).
I have a couple [no idea where I got them] but would like to use these for a prototype cause I hate crimping.
Looks like an AMP IDC? That six-conductor looks a lot like https://www.te.com/usa-en/product-3-640440-6.datasheet.pdf

After buying these MTA 100 connectors on eBay, I looked for an insertion tool.
Wow! They seemed hard to find and very $$$.
It seems a carefully ground screwdriver will work well enough.

Do IDC 110 punch down tools not work? The blades look a lot like the tool you made…

Yeah, like that one. They usually have both impact and low- or no-impact settings, and three blade is usually reversible with a cutting and a non-cutting end.
It used to matter whether you got one that also includes a 66-block blade, but in these post-POTS days, who uses 66-block any more?

I thought the same! Of course I have one of those…
But the ridges on the sides of the tool prevent entry.
I needed the tool today so employed an old screwdriver.
That said now that I have proven this works I will buy one of these 110 punch down tools and grind it.

I received the punch-down tool highlighted above.
It has a couple of features I did not anticipate:
- It’s an impact tool. Press down and it releases the spring. 2 impact settings
- Removable 2-sided bit. One side has a cutter.
- Quick-release collar.
- The bit can be stored in the handle
I reground the non-cutter side. The other side is still useful as a standard punch-down tool.
I regound the tool to fit the spacing on the IDC connector housing. The tool profile fit perfectly the arc on my 8" grinder so all I had to do was hold it horizontally on the wheel to reduce its thickness.
I found that the best fit was with one side ground slightly thicker than the other.
I also ground off the front of the tool since the gap was too long for this application.
It looks like the insulation was penetrated properly.
