I've got this housing plug that I need to squish some wires into, but I think I need a specific kind of tool in order to get them in there. I think the plug is designed to penetrate the plastic shielding around the wires. The connector has "U-2 amp" on it, and no other markings. It's for a bowling alley computer. I haven't had any success figuring out what it is from Google, as it's also probably very old.

Thank you.

 

It looks like it may be crimped with a Panduit MRT-156F tool.

Likely a MTA (Mass Termination Assembly ) 100

The official hand tool is this:

I have one of those tools. It is made of plastic and the centre pins last for only so long.
I repaired it by inserting square metal pins to replace the worn plastic pins.

 

Thank you so much! That looks exactly right. I've ordered a tool for it.

 

We called them IDC (Insulation Displacement Connector) type connectors. They are more frequently seen to connect ribbon wire to a header. There should also be a cover that snaps on, once the wires are pressed down on the conductive pins.

That the same as my Panduit version.
