Hello all,
I'm not a beginner to electronics, but I am a beginner to electronics that take power from the wall! I am repairing an old radio with a busted power supply, and it takes a "universal" 2-pin cord to get 120V from the wall here in USA.
As I was drawing a DaveCAD-style schematic of what the power supply was all about, I noticed that the power connector has 5 pins! Very weird, I only expected 2 to get fed into the transformer. So I decided to look up power connectors on Mouser to see what those 3 are about, and I can't find any similar parts! I looked under "power to board", and filtered on "120V", and nada! Zip! Zilch! What gives?
So here are my questions. (Pictures of connector attached):
1) Is there an official name for the universal 2-pin connector? (example of mating cable:
https://www.amazon.com/gp/product/B01HPWIDVS/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1) Is IEC-320-C7 what I'm looking for?
2) What are those 3 extra pins for? There are traces going to them, so they aren't just mechanical bosses, surely?
3) Why didn't my Mouser search reveal any similar parts? Are these type of connectors no longer used?
Thanks for any help you can offer!
