The wall insertion type USB direct current output socket provided by the utility model carries out direct current output through the USB female socket, and a user can meet charging requirements of a plurality of electronic products by only configuring a USB. Furthermore, the wall insertion type USB direct current output socket can realize multi-gear adjustment on output current, thereby ensuring the electronic products not to be damaged by improper power supply while improving the charging efficiency.
Description
Technical field
The utility model relates to wall and inserts formula socket.
Background technology
Traditional electronic product charging modes is all each electronic product, is all furnished with a special charger, by charger, civil power alternating current is transferred to the charging current suitable with this electronic product, then electronic product is charged.On the other hand, along with the propelling of electronic product standardized process, current most electronic product all adopts USB interface, couples together, then charge by USB bundle of lines electronic product and charger.A charger only has an output mode, makes like this each electronic product need to be equipped with a charger, uses inconvenient.
Utility model content
Not enough for above-mentioned prior art, the technical problems to be solved in the utility model is to provide a kind of socket that can meet multiple electronic product use.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is that wall is inserted formula USB direct current accessory power outlet, comprises USB female seat, switch power module, multi-gear switch and AC terminal; Described AC terminal is connected with the input of switch power module by multi-gear switch; Described multi-gear switch is at least two driving switch; The output of switch power module and USB female seat conduct.
Preferably, also comprise panel and bonnet; Switch power module is placed in the cavity of panel and bonnet formation; USB female seat and multi-gear switch are located on panel; AC terminal is located on bonnet.
Preferably, described multi-gear switch is third gear toggle switch; This third gear toggle switch has four pins, and the first pin of third gear toggle switch is all connected with one of them terminals of AC terminal with the 4th pin, and other terminals of AC terminal are connected with switch power module; The second pin of third gear toggle switch is connected with the input of switch power module respectively with the 3rd pin.
Wall of the present utility model is inserted formula USB direct current accessory power outlet and is carried out direct current output by USB female seat, and user only need configure the charging needs that USB line can meet a plurality of electronic products; In addition, can realize many gears regulation output electric current, when improving charge efficiency, ensure that again electronic product can not damage because of incorrect power supply.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model wall is inserted formula USB direct current accessory power outlet.
Fig. 2 is the circuit theory diagrams that the utility model wall is inserted formula USB direct current accessory power outlet.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, wall of the present utility model is inserted formula USB direct current accessory power outlet, comprises panel 1 and bonnet (scheming not shown).Described panel 1 is provided with USB female seat 11 and third gear toggle switch 12; Described bonnet is provided with AC terminal 3, and described AC terminal 3 comprises hot terminal and zero line terminals.Also comprise switch power module 2, described switch power module 2 is placed in the cavity of panel 1 and bonnet formation.Third gear toggle switch 12 has four pins, the first pin of third gear toggle switch 12 is all connected with one of them terminals of AC terminal 3 with the 4th pin, in the present embodiment, the hot terminal of AC terminal 3 is connected with the 4th pin with the first pin of third gear toggle switch 12.Other terminals of AC terminal 3 (being zero line terminals in the present embodiment) are directly connected with switch power module 2.It is pointed out that the problem of considering Electrical Safety, a lot of walls are inserted formula socket and are all provided with earth connection, and general earth connection is all that the part connecting as alternating current is connected with civil power; But those skilled in the art are according to description of the present utility model, in known the present embodiment, AC terminal 3 of indication refers to the part that realizes Alternating Current Power Supply, be the part that the terminals of earth connection should not be construed AC terminal 3 of the present utility model, earth connection is not connected with third gear toggle switch 12.The second pin of third gear toggle switch 12 is connected with the input of switch power module 2 respectively with the 3rd pin.The output of switch power module 2 and USB female seat 11 conduct.In the time of in the middle of third gear toggle switch 12 is allocated to, the connection of AC terminal 3 is disconnected by third gear toggle switch 12, and alternating current cannot enter switch power module 2, and switch power module 2 is not worked, without direct voltage output, realize idle and extend capacitor useful life; USB female seat 11 is output current not also.When third gear toggle switch 12 dials to upper end or lower end, switch power module 2 is started working, and externally output current, different according to the gear of selecting, to the different electric current of same USB female seat 11 output, make user's electronic product only need can realize charging demand by a USB line.In the present embodiment, two grades of electric currents of output are respectively 1A and 2.1A, by selecting different electric currents to charge to different electronic products, have both guaranteed charge efficiency, protect again electronic product can not damage because electric current is excessive.Third gear toggle switch 12 is only a kind of preferred way of realization, and actual enforcement can adopt other multi-gear switchs such as third gear rotary switch.In addition also can adopt the switch of more gears, switch power module 2 correspondences realize more multi-output current form.Also can adopt two gear switch, minute two kinds of electric current outputs, and cancel the function of closing direct current output.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
