Description
Technical field
The utility model belongs to the design field of power supply adaptor, specifically, relates to a kind of multi-adapter of Functional Design of expansion of power supply adapter.
Background technology
For whole notebook computer, the importance of power supply is absolutely not low than CPU, and the stable operation of whole notebook computer depends on power supply provides lasting, stable magnitude of voltage.Because notebook computer generally adopts direct supply to drive, and the power supply normally AC power that user adopts, as China adopts the alternating current of 220 volts, therefore notebook computer can be equipped with a power supply adaptor usually.The basic functional principle of power supply adaptor High Level AC Voltage (alternating currents as 220 volts) is converted to low-voltage DC needed for notebook computer by high-frequency switching technology.In alternating current and galvanic transfer process, due to the restriction of state-of-the art and the characteristic of electronic devices and components itself, the energy some becomes heat energy, distributes among air with the form of heat, thus gives the sensation of high temperature.In addition, power supply adaptor works in the case of a high temperature and can reduce to some extent than serviceability at normal temperatures, and it is mainly reflected in output power and reduces.
Chinese patent CN102981589A discloses a kind of power supply adaptor, comprise housing, described housing has the chamber of collecting circuit board, one or more secondary cavities that described chamber comprises main chamber and extended by described main chamber, and described main chamber and each described secondary cavity are interconnected; Described circuit board comprises the main board be arranged in described main chamber and the subplate being arranged at secondary cavity.The power supply adaptor that this invention provides, what the electronic devices and components in power supply adaptor can be made to disperse is arranged in main chamber and secondary cavity, thus the heat making it produce is easy to shed.In addition, for preventing gathering between the junction of heat main chamber and each secondary cavity, described main chamber and each described secondary cavity being interconnected, keeping the integraty of chamber, to prevent heat radiation dead angle.
Although this patent structure is very simple, multiple computer can not be suitable for, can not separately as USB charging equipment.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art part, the purpose of this utility model be to provide a kind of structure simple, be applicable to the multi-adapter that carries, to overcome defect of the prior art.
To achieve these goals, the utility model provides a kind of multi-adapter, described multi-adapter comprises the adaptor body being provided with synchronous rectification module, the input end of described adaptor body is electrically connected with plug by input connecting-disconnecting interface, the output terminal of described adaptor body is electrically connected with power supply termination by exporting connecting-disconnecting interface, USB interface is provided with between described output connecting-disconnecting interface and described power supply termination, described power supply end is provided with pull down resistor, and described pull down resistor is electrically connected with described synchronous rectification module.
As further illustrating multi-adapter described in the utility model, preferably, the shell of described adaptor body is provided with to touch and wears louvre.
