Abstract
The application discloses a power adapter for a laptop. The power adaptor comprises a shell and a PCB (printed circuit board ) accommodated in the shell, wherein a voltage conversion circuit and a gear toggle switch are arranged on the PCB; a voltage input end and at least a two-level voltage output end are arranged on the voltage conversion circuit; the gear of the gear toggle switch corresponds to the voltage output end, so that the gear of the voltage output can be selected by toggling the gear toggle switch; the voltage input by the voltage input end is converted by the voltage conversion circuit into a voltage corresponding to the gear and the voltage is output. Therefore, the power adapter for the laptop can supply various output voltages and meet the requirements of laptops or electronic equipment with various working voltages.
Description
Technical field
The application relates to electronic equipment corollary apparatus field, relates in particular to a kind of laptop adapter.
Background technology
At present, notebook is as the standing electronic equipment of people's Working Life, and it is generally powered by power supply adaptor.Power supply adaptor can be that the input voltage of 100-240 volt is converted to 19 volts of notebook operating voltage by civil power.
But, because power supply adaptor is only exported 19 volts of voltages, only supply specific a kind of notebook special, when the notebook of adaptive other operating voltage of needs or electronic equipment, existing power supply adaptor seems helpless.
Summary of the invention
The application provides a kind of laptop adapter, so that voltage in several modes to be provided, meets dissimilar electronic equipment demand.
The application provides a kind of laptop adapter, comprise: shell and be placed in the pcb board in shell, on this pcb board, be provided with voltage conversion circuit and gear toggle switch, described voltage conversion circuit is provided with a voltage input end and two-stage voltage output end at least, and the gear of described gear toggle switch is corresponding with voltage output end.
Further, described voltage conversion circuit comprises the primary coil with described voltage input end, and is provided with the secondary coil of described voltage output end.
Further, on described pcb board, be provided with USB interface, on described secondary coil, be provided with a USB voltage output end that supplies power to this USB interface.
Further, on described pcb board, be also provided with the output circuit as described voltage conversion circuit output, described gear toggle switch comprises the displacement portion that is provided with this output circuit access contact, and the limitting casing that is provided with described voltage output end and moves between each voltage output end for described displacement portion, this limitting casing is provided with pilot hole in each voltage output end correspondence position, is provided with the positioning convex point that coordinates location with described pilot hole in described displacement portion.
Further, described gear toggle switch also comprises and is nested in the forced section for user's application of force in described displacement portion.
The application's beneficial effect is:
By a kind of laptop adapter is provided, comprise shell and be placed in the pcb board in shell, on this pcb board, be provided with voltage conversion circuit and gear toggle switch, described voltage conversion circuit is provided with a voltage input end and two-stage voltage output end at least, and the gear of described gear toggle switch is corresponding with voltage output end.Like this, by stirring gear toggle switch, just can select the gear of output voltage, make the voltage of voltage input end input after voltage conversion circuit carries out voltage transitions, convert the Voltage-output that this gear is corresponding to, make laptop adapter that voltage in several modes can be provided, meet the demand of various operating voltage notebooks or electronic equipment.
