Original Famicom Connector Pins?

[ThatOneSystem]

Hi. Looking around, I have noticed that my Famicom has different pin connectors than other round button non-VCCI Famicoms. I know it's not a problem but I was just curious and wanted to know if these types of connectors came in newer models of round button non-VCCI Famicoms, or if it was something added in from the person who sold it to me.

That's an original part, a few of my Famicoms have them.

Even non-VCCI (The ones without the FF Label next to Family Computer) ones? Interesting. I've never seen them before in the older models. Guess some models of the round button Famicom have them and some don't?
