Abstract

The utility model relates to a power supply line socket with USB interfaces which relates to the technical field of power supply equipment, in particular a power supply line socket that can be simultaneously used as the power supply and the computer USB interface distributor. The technical proposal is that the line socket is provided with AC/DC conversion circuit; the B-type input jack of the USB and a plurality of A-type output jacks of USB, the AC/DC converter and input power supply of the line socket are connected, and the output is connected with the A-type output jacks of the USB; meanwhile, the B-type input jack of the USB and the A-type input jack of the USB are connected. While realizing power supply distribution, the utility model can realize distribution of the USB standard interface. The same product has multifunction and the use is convenient use and can save the cost.

Description

The power distributor that has USB interface

Technical field:

The utility model relates to the power supply equipment technical field, refers in particular to a kind of power distributor of can be simultaneously using as power supply supply and computer USB interface divider.

Background technology:

Computer along with improving and development of its technology, function, also becomes important day by day in people's life, the effect in the work; But, for present desktop computer, generally all including display, main frame, its external equipment mostly includes scanner, digital camera, keyboard, mouse etc.; For notebook computer, also often need to connect external equipments such as scanner, digital camera, mouse; Therefore, in use, usually need a plurality of AC Power supply socket and a plurality of USB interface; For satisfying the demand of a plurality of AC Power supply socket, at present, people's utilization is imported AC power one and is powered when the power distributor that is divided into many output ports is realized various device; But,, want the equipment that a plurality of USB standard interfaces connect connected simultaneously and work and can't directly realize because the USB interface on the existing computer has only two or can't provide more convenience at most; Be head it off, also once had the house of producing to produce a kind of USB interface divider of special use, it is many to realize that one of USB interface is divided into; But, for the user, both need use power distributor, buy the USB interface divider again, the cost of its use is higher relatively, too many equipment, also not too conveniently laying and use; And USB interface divider itself can't provide the power supply of capacity for the equipment that connects, and when many equipment connect simultaneously, its electric current can't satisfy the demands.

Summary of the invention:

It is a kind of when AC power one input is divided into many output that the purpose of this utility model is to provide, and also has the power distributor of the USB interface distributor function on the computer.

The utility model is achieved by the following technical solution: be provided with the Type B input female seat of AC/DC change-over circuit, USB and the A type output female seat of some USB in socket, the AC/DC converter links to each other with the alternating current input power supplying of socket, and its output links to each other with the A type output female seat of each USB; The Type B input female seat of USB is also exported female seat with the A type of USB.

The output voltage of AC/DC change-over circuit is the 5V direct current; The quantity of the A type output female seat of USB is more than three; The A type output female seat supply pin of the output of AC/DC change-over circuit and USB joins.

The utility model can be divided into a plurality of ac output end mouths with an AC power input interface, for a plurality of equipment provide AC power simultaneously; Simultaneously, scanner, digital camera, keyboard, mouse etc. can also be linked to each other with computer by the equipment that the USB standard interface is connected with computer simultaneously; Overcome the problem that can't connect a plurality of equipment and power shortage because of the computer USB standard interface very little simultaneously; In actual application, only need disposable equipment is connected upward to get final product, and need not repeatedly to connect, saved the time that equipment connects, help improving office efficiency; In addition, on identical product, realize multiple difference in functionality, help saving use cost, reduce the space of hold facility, make surrounding environment cleaner and tidier.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further specified:

Accompanying drawing 1 is the utility model structure principle chart;

Accompanying drawing 2 is implemented the product schematic perspective view for the utility model.

Embodiment:

See accompanying drawing 1,2, the utility model is provided with the Type B input female seat 3 of AC/DC change-over circuit 1, USB and the A type output female seat 2 of some USB in socket; The alternating current of 110～220V that AC/DC converter 1 will be imported converts the direct current of 5V to, and the A type that AC/DC converter 1 is output as this direct current by being connected with the A type of USB output female seat 2 supply pins each USB is exported the equipment that female seat 2 connected power supply is provided; In addition, the Type B of USB input female seat 3 links to each other with the A type output female seat 2 of each USB, and realization auxiliary device such as scanner, digital camera, keyboard, mouse etc. are connected with desktop computer or portable computer signal data.

When using the utility model, for each equipment provides AC power, can be connected with interchange output interface 4 in the socket by power lead and get final product as in advance; And be to realize that the equipment that a plurality of USB standard interfaces connect links to each other simultaneously with computer, can the USB interface on the computer be linked to each other with the Type B input female seat 3 of USB with USB connecting line 5 and (annotate: 5 transmitting signals of USB connecting line); Simultaneously, each equipment 6 (as scanner, digital camera, keyboard, mouse etc.) is connected with the A type output female seat 2 of USB by USB connecting line 7; So, then the USB interface on the computer is connected with Type B input female seat 3, the A type output female seat 2 of USB, the USB connecting line 7 of equipment 6 by USB connecting line 5, USB; When reality was used, the equipment 6 that need be connected with computer was opened moving getting final product, and need not repeatedly connection device 6.
