An electronic device with a detachable plug capable of changing plugging direction is disclosed. The electronic device comprises a main body and a plug. The main body has a plug-receiving portion, and the plug-receiving portion comprises at least two conducting pieces. The plug has a plug body and at least two conductive terminals. The plug body comprises four trenches disposed at a bottom thereof and arranged as a square. Each of the conductive terminals comprises a plugging portion, a connection portion and an extension portion, wherein the plugging portion is protruded out of a surface of the plug body, and the connection portion and the extension portion are embedded in the plug body and are corresponding to two adjacent trenches, respectively. Thereby, when the plug is assembled on the plug-receiving portion of the main body, the two conducting pieces are respectively received in two opposite trenches and contacted with either the two connection portions or the two extension portions of the two conductive terminals for power conduction.

An auto-return pivot system for a display apparatus is provided. The auto-return pivot system comprises a base fixed to an article; a pivot fixed to the base; a support pivotally mounted around the pivot for supporting the display apparatus; a cam device connected with the support to determine a stop angle and an auto-return angle between the article and the support; and a pressure-storing device connected with the cam device for storing a pressure to be applied to the cam device in the axial direction of the pivot; wherein the pressure from the pressure-storing device enables the cam device to drive the support to automatically return to a position with the stop angle when an angle between the article and the support is smaller than the auto-return angle.

A transformer includes a bobbin, an I-bar, the first U-core, and the second U-core. The bobbin in a tube shape is wrapped around by a number of windings of copper coil. An I-bar made of high permeable alloy has a first end and a second end. The I-bar is inserted into the bobbin and the first end and the second end of the I-bar protrude outside the tube of the bobbin respectively. A first U-core made of high permeable alloy is placed on one side of the bobbin and a second U-core made of high permeable alloy is placed on the other side of the bobbin. The two ends of the first U-core and the second U-core connect the I-bar through the films and the sunken parts of the first U-core and the second U-core are in opposition to each other.

A modular power connector includes an insulation main body, at least one conducting element, at least one electricity-delivering element, and at least one engaging element. The conducting element is partially accommodated within the insulation main body, and includes a perforation. The electricity-delivering element has a bare part at an end thereof. The engaging element is fixed on the bare part of the electricity-delivering element, and includes an elastic extension part and a stopping part. The elastic extension part is subject to elastic deformation during the elastic extension part is penetrated through the perforation of the conducting element. The elastic extension part is restored to an original shape after the elastic extension part is penetrated through the perforation, so that the conducting element is clamped between the elastic extension part and the stopping part.
