Power Cable will not fully insert. Help.

@roxy54  thanks. I brushed a microscopic amount of deoxit and it cut the distance in half so I’m leaving it. Nothing exploded (yet). 
 

thanks 😊

Yes, for some reason that sometimes happens, as roxy54 said no big deal, it will be fine.

Dump this cable ASAP!!

Calm down Edward.

You should have received a slip of paper with the cable noting that the connector can be very tight. That’s so that an excellent grip can be achieved. In cases where it’s very tight, I believe it’s recommending that you gently insert and remove a wooden toothpick between the three pairs of gripper plates. A little at a time, as you don’t want to loosen it too much.  Just be sure the toothpick is strong enough so that it doesn't break.  Not sure about the alternative of using a small flathead screwdriver.  It's metal on metal, but then the connector to the socket is metal on metal too.
