Abstract

The utility model relates to the technical field of part spraying and discloses an anti-misplug guiding assembly of a charging plug, which comprises an insulating shell and a connector, wherein a first telescopic column is fixedly connected inside the insulating shell, a first compression spring is sleeved on the outer wall of the first telescopic column, a fixed block is fixedly connected with the other end of the first telescopic column, a plurality of fixed rods are fixedly connected to the top of the fixed block, the outer wall of the fixed block is slidably connected to the inner wall of the insulating shell, a plurality of pins are fixedly connected to the outer wall of the insulating shell, and a clamping assembly is arranged inside the insulating shell. In the utility model, when the plug is connected into a normal socket, the traction block is pulled to drive the extension pipe to extrude the second spring to retract into the sleeve, and as the socket does not have a clamping groove, when the plug approaches, the plane of the socket contacts the fixing rod, so that the fixing block extrudes the first spring to slide, extrudes the second limiting column to compress the second spring, and finally the second spring pushes the second limiting column to clamp into the fixing block groove, thereby realizing stable connection.
