Abstract
An object is to provide a DC power supply connector that can suppress occurrence of an arc discharge at DC power off with a small-scale configuration without reducing power efficiency during DC power supply and can reduce heat generation. The connector includes, on at least any of a positive-electrode-side electrode side and a negative-electrode-side electrode side, a movable contact piece () that touches a first contact () in a state where a terminal () on a power receiving side has been inserted and to touch a second contact () in a state where the terminal has not been inserted, and a current limiting circuit () including a switching element (T). The current limiting circuit () does not flow a current to the switching element (T) in the case where the movable contact piece () is touching the first contact (), and flows a current to the terminal () through the movable contact piece () until the movable contact piece () is linked to the second contact () after separation from the first contact (), and gradually decreases the flowing current.
