content: I’m not sure what the part is called, but the picture seems to be a evaluation board. If you have a look around, maybe the evaluation board maker has a Bill Or Materials available? That would contain the connector details.

content: THANKS A LOT my man!!!!! Yeah I finally could find several parts. Digikey being my preferred vendor, I found a whole section of these (https://www.digikey.com/product-detail/en/panduit-corp/LAMA2-14-QY/298-10109-ND/317639)Yeah i think I will go with something like 2-4 AWG.
