Abstract: A secondary battery includes a battery case configured subject to the configuration of a conventional 9V or 1.5V battery and a battery body and a battery charger mounted in the battery case. The battery charger controls the battery body for charging and voltage output, and provides a USB socket as charging interface and positive and negative electrodes as discharging interface. Thus, the secondary battery is connectable to a USB plug of a cell phone battery charger or computer for charging, and can be installed in an electric product like a conventional battery cell to provide DC power to the electric product. Under the provision of current detection function and voltage adjusting function, the 1.5V secondary battery can be connected in series or in parallel with one or a number of micro resistor-provided virtual batteries to output a voltage subject to its linking arrangement.

Abstract: An electrical connector includes a base, terminals each being disposed on the base and having a contact, and one pair of switch terminals, disposed on the base, including first and second terminals each having a fixing portion, a pin portion and an extension. The base has a connection slot for accommodating an electronic element. The first and second terminals have the fixing portions, each fixed to the base and having a plateless section. The extensions respectively have corresponding connection points. The extension of the first terminal has a pushing portion. The electronic element is inserted into the slot to push the pushing portion to make the extension of the first terminal be elastically moved to touch the switch terminals.

Abstract: The present invention discloses a motor. A rotor and bearings are installed first and then copper wires are wrapped by a machine. Therefore, the copper wires wrapped are denser and thinner that a space filling factor is improved and an entire size of the motor is reduced. In addition to saving of electricity consumption and improvement of motor performance, the bearings are directly enclosed in two insulation plates to isolate from ambient environment, so that dust contamination can be reduced and noise from operation can be decreased, thereby extending a service life of the motor. Furthermore, packing and transportation costs can be even saved. Additionally, the insulation plates include plural insertion slots for insertion with copper plates which are electrically connected with a motor power cord. Thus, an inner stator can be connected with the power cord by plugging, so as to save labor work and time.
Abstract: An electrical connector includes a plastic base and an engaging member. The base has a longitudinally extended connection slot to be connected to a circuit board having one side formed with a notch. The engaging member disposed on one side of the base has an elastic arm, which has a handle, a guide-in inclined surface, an engaging portion and an elastic member. When the circuit board is inserted into the slot, the one side thereof presses the guide-in inclined surface to make the arm elastically move outwardly. When the arm elastically moves back, the engaging portion engages with the notch. When the handle is moved to make the arm elastically move outwardly and to disengage the engaging portion from the notch, the elastic member can stop the engaging member from elastically moving back to engage with the notch, so that the circuit board can be conveniently taken out.
