Abstract: A portable electronic device including a main body and a connecting port is provided. The main body has an containing cavity. The connecting port includes a base and at least one movable component. The base is disposed at the main body. The movable component is movably connected to the base and moves between an accommodated position and an operation position relatively to the base. When the movable component is located at the accommodated position, the height of the connecting port is less than or equal to the height of the containing cavity such that the connecting port is adapted to be accommodated in the containing cavity. When the movable component is located at the operation position, the height of the connecting port is greater than the height of the containing cavity, and a connector is adapted to be fixed between the base and the movable component.

Abstract: A power connector suitable for being mounted on a circuit board includes an insulating housing and a center terminal. The insulating housing has a plug hole. The center terminal has a center fixing portion, a center contact portion and a center soldering portion. The center fixing portion is fixed into the insulating housing, the center contact portion extends into the plug hole, and the center soldering portion is suitable for passing through a center soldering hole of the circuit board to be soldered to the circuit board. The center soldering portion has a waist segment and a tail segment extending from the waist segment, the waist segment is located inside the center soldering hole, and the minimum transection area of the waist segment is less than the maximum transection area of the tail segment. A center terminal suitable for being utilized in a power connector is also provided.

Abstract: An electrical connector includes a first terminal and a second terminal. The second terminal is fixed at the first terminal and enclosed by the first terminal, in which the second terminal includes a tube-shaped structure, the tube-shaped structure has a clipping portion and two end-surfaces, the two end-surfaces lean against each other to form a seam. The inner diameter of the clipping portion is smaller than the inner diameters of other portions of the tube-shaped structure. When a third terminal of a coupling connector is inserted into the tube-shaped structure to make the tube-shaped structure elastically deformed, the two end-surfaces are separated from each other and the clipping portion clips the third terminal.

Abstract: A portable electronic device including a main body and a connection port is provided. The main body has a containing cavity. The connection port includes a supporting component and a connector. The supporting component is slidably disposed at the main body along a sliding direction and slides between an accommodating position and an operation position relative to the main body. The connector is disposed on the supporting component and has a plugging direction. When the supporting component is located at the accommodating position, the connector is contained in the containing cavity and the plugging direction is perpendicular to the sliding direction. When the supporting component is located at the operation position, the connector is located out of the containing cavity, and the supporting component has a tilting angle relative to the main body.
