Abstract: A receptacle connector includes an insulating portion, a receptacle terminal module mounted to the insulating portion, a metal shell enclosing the insulating portion, and a receptacle circuit board. The insulating portion includes a receiving space and a mating space extending from the receiving space. The mating space extends through the insulating portion to form a mating port. The receptacle terminal module includes a first terminal module and a second terminal module. The first terminal module and the second terminal module have a same structure, and are symmetrically arranged on opposite sides of the mating space. The first terminal module and the second terminal module are electrically connected to the receptacle circuit board.

Abstract: The present application discloses a control method, a control system, and a device for a grab of a portal crane. The control method for a grab of a portal crane includes: acquiring a height information of the grab; acquiring an amplitude variation information of a luffing mechanism; acquiring a slewing angle information of a rotation of a slewing mechanism; determining a horizontal relative position information of the grab relative to a center point of the slewing mechanism according to the amplitude variation information and the slewing angle information; determining an actual position information of the grab relative to the center point of the slewing mechanism according to the horizontal relative position information and the height information; acquiring a scanning information of a hull, and determining a position information of a material; and planning an operation route of the grab.
