Abstract: A rechargeable battery includes a battery body and a connector plug. The battery body has a recess, a circuit board and a cell. The circuit board is electrically connected to the battery cell. The connector plug is pivotally connected to the battery body and electrically connected to the circuit board. The connector plug is foldable to be received in the recess. Accordingly, the connector plug is pivotally connected to the battery body and is foldable to be received in the recess, so the battery body can be charged by means of the connector plug connected to an external power supply, thereby improving convenience in using the rechargeable battery.

Abstract: A composite connection socket includes a metal housing, an insulative main body, a first row conductive terminal and a second row conductive terminal. The metal housing includes an accommodating space formed therein, and the insulative main body is received inside the accommodating space. The insulative main body includes a first side plate, a second side plate and a base; the first side plate and the second side plate are arranged corresponding to each other and protrude from the base. The first row conductive terminal is arranged on the first side plate and complies with a micro USB communication protocol interface. The second row conductive terminal is arranged on the second side plate and complies with a lightning standard interface. The composite connection socket is able to commonly accommodate two cable connectors of different standards of a micro USB connector or a lightning connector inserted therein.

Abstract: A socket outlet includes a main module and an expansion module. An expansion socket formed with a through hole, an inner annual groove, and an outer annual groove is disposed on the main module. Three electrodes are disposed on the expansion socket, respectively extended into the through hole, the inner annual groove, and the outer annual groove. An expansion plug including a conductive pin, an inner conductive ring, and an outer conductive ring is disposed on the expansion module. The expansion plug is plugged in the expansion socket, the conductive pin is plugged in the through hole, the inner conductive ring is plugged in the inner annual groove, and the outer conductive ring is plugged in the outer annual groove. The expansion module is connected to the main module by plugging the expansion plug into the expansion socket. The expansion module and the main module can be relatively rotated.
