Abstract
The utility model discloses a kind of power protection computer host box; power protection computer host box inner top side screw is fixed with a power pack; power pack inner bolt is fixed with power module and transformer; power module is welded with input interface and output interface; input interface is connected with circumscripted power line; output interface is connected with host supplying power line, and a terminal circuit of transformer connects output interface, and the other end circuit of transformer connects USB interface.What transformer connected one end output of USB interface is 5V direct current.Power protection computer host box inner top side is provided with a power pack, makes computer computer when unexpected power-off power supply can be provided to work on by power module, is unlikely to shutdown suddenly and causes loss of data.Disconnect the connection of host supplying power line and power module output interface during shut down of computer, the 5V direct supply of USB interface still exists, can ensure computing machine auxiliary device normal through USB interface powered operation.
Description
Technical field
The utility model relates to computer realm, particularly relates to a kind of power protection computer host box.
Background technology
Desktop computer is when unexpected power-off, and abnormal shutdown easily causes loss of data.And pull out attaching plug or the unexpected power-off of circuit inevitably occurs in life by mistake.This using desktop computer bring very large inconvenience.
On market, computing machine auxiliary device miscellaneous is run by the power supply of computer export simultaneously, if user only wants that using auxiliary device must open computing machine could use, and so both wastes electric energy and also loses time.
Utility model content
The purpose of this utility model is to provide a kind of power protection computer host box, has protection power source, and the USB interface of not power-off.
For achieving the above object, the technical solution of the utility model is:
A kind of power protection computer host box; in described power protection host computer box main body, installation has a power pack surely; described power pack is provided with power module and transformer; described power module is provided with input interface and output interface; described input interface is connected with circumscripted power line; described output interface is connected with host supplying power line, and described transformer is connected with output interface by circuit, and described transformer is also connected with the galvanic USB interface of output 5V by circuit.
Described power protection host computer box main body is also provided with sound equipment.
The utility model can reach following beneficial effect: the utility model is provided with a power pack by power protection computer host box inner top side; make computer computer when unexpected power-off power supply can be provided to work on by power module, be unlikely to shutdown suddenly and cause loss of data.Disconnect the connection of host supplying power line and power module output interface during shut down of computer, the 5V direct supply of USB interface still exists, can ensure computing machine auxiliary device normal through USB interface powered operation.Power protection host computer box main body is provided with sound equipment can use when there is no earphone and boom box.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
As shown in Figure 1; a kind of power protection computer host box; comprise power protection host computer box main body 1; in described power protection host computer box main body 1, installation has a power pack 2 surely; described power pack 2 is provided with power module 3 and transformer 4; described power module 3 is provided with input interface 5 and output interface 6; described input interface 5 is connected with circumscripted power line 7; described output interface 6 is connected with host supplying power line 8; described transformer 4 is connected with output interface 6 by circuit, and described transformer 4 is also connected with the galvanic USB interface 9 of output 5V by circuit.Described power protection host computer box main body is also provided with sound equipment.Power protection computer host box inner top side is provided with a power pack, makes computer computer when unexpected power-off power supply can be provided to work on by power module, is unlikely to shutdown suddenly and causes loss of data.Disconnect the connection of host supplying power line and power module output interface during shut down of computer, the 5V direct supply of USB interface still exists, can ensure computing machine auxiliary device normal through USB interface powered operation.Power protection host computer box main body is also provided with sound equipment 10 can be for subsequent use when not having earphone.
