DIN fitting was originally brought into line in the 1970s. It is an electrical connector, and its architecture has multiple pins under a protective circular sheath. Normally, a full-sized din connector contains three to 14 pins with a diameter of 13.2 millimetres. The term din connector doesn't refer to a specific cable. Instead, it requires all the connectors that meet the din standard. The circular connector is another name for din connector in computer electronics.
