CN221885504U - A power cord connection device - Google Patents

Abstract

The utility model relates to the technical field of power cords, and discloses a connection device for a power cord, comprising a first plug and a second plug. The utility model inserts two insertion rods into a slot at the same time, and then rotates the second plug. The second plug drives a movable rod to rotate inside an arc groove, and the arc groove drives the insertion rod to rotate inside the movable groove. When the insertion rod moves to the inclined surface of a sliding rod, the sliding rod is subjected to the force of the insertion rod, causing it to squeeze a spring and slide toward the inside of a fixed sleeve. When a connection hole inside the insertion rod passes through the sliding rod, it exerts no force on the sliding rod, causing the sliding rod to perform a reset movement under the influence of the elastic force of the spring, so that the sliding rod enters the inside of the connection hole. At the same time, an insulating block enters the sealing groove and contacts the inner wall thereof, and a connector enters the electrical interface and contacts the electromagnetic sheet, so that the connection between the first plug and the second plug can be completed. The installation and disassembly are simple and quick, the connection strength is high, and the device is not easy to fall off.
