I have gotten E3615A power supply that was broken terminal part.
And this power supply is retired at some company's office.
So I have designed repair parts for this power supply.
And I found similar terminal part from Aliexpress as below.
But it is not matched with E3615A.
So I have desinged coupler parts for E3615A body and also other Agilent same terminal.
Method is use plastic nut that has been used in Agilent.
My designed coupler matched with original plastic nut and also matched hole size of Agilent.
