Power connector having interlock function and power connector device using power connector

A power connector comprising:

• a housing having at least two fitting portions each fittable to at least two partner fitting portions of a partner connector in an abutting state;
• at least two terminals each arranged at the at least two fitting portions;
• and
• at least one interlock connector attached to an attachment portion of the housing,
• wherein when the at least two fitting portions and the at least two partner fitting portions are fitted to each other, the at least two terminals are each electrically connected to at least two partner terminals each provided at the at least two partner fitting portions, and the at least one interlock connector is configured to be in conduction with a partner interlock connector provided at the partner connector,
• at an abutting surface of the at least two fitting portions and the at least two partner fitting portions, the attachment portion is positioned between peripheral edges of the at least two fitting portions, and is arranged in a region excluding a most-proximal portion where the peripheral edges of the at least two fitting portions are closest to each other in an array direction of the at least two fitting portions, and
• at the abutting surface, the attachment portion includes at least two attachment portions provided at positions sandwiching the most-proximal portion in a direction perpendicular to both of a fitting direction of the at least two fitting portions and the at least two partner fitting portions and the array direction.
