Abstract
A dual-protection power socket with a USB interface comprises a socket body and a power supply section, wherein a power switch for switching on/off the power supply section and jacks are arranged on the socket body; insert units corresponding to the jacks and connected with the power supply section are arranged in the socket body; a lightning protection circuit and an overload protection circuit are sequentially arranged between the power supply section and the power switch; the power supply section is also connected with a USB voltage transformation conversion circuit; and a USB interface connected with the USB voltage transformation conversion circuit is arranged on the socket body. The dual-protection power socket provided by the utility model has the advantage that the USB interface is added on the conventional power socket, so that the power socket can be used for charging an electronic product only by connecting the USB data line with the USB interface, thereby widening the use range of the conventional power socket and improving use convenience. Meanwhile, the added overload protection circuit and the lightning protection circuit can switch off the power supply to stop running of electrical appliances immediately when overload or lightning stroke occurs, thereby realizing dual-protection effect and enhancing use safety.
Description
Technical field
The utility model relates to a kind of supply socket, relates in particular to a kind of duplicate protection and with the supply socket of USB interface.
Background technology
Supply socket great majority in the market all are the common power sockets; The various jacks of output AC 220V only are provided; This jack can not satisfy the needs of mobile phone, digital camera and electronic products such as MP3, MP4, and people must adopt the power source special transducer and the USB connecting line of band USB interface just can accomplish to these electronic product chargings the time; Particularly when out of town trip, very inconvenient.In addition, on anti-thunderbolt and overload protection, existing supply socket also haves much room for improvement.
Summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides a kind of simple in structure, easy to use, supply socket of having overload and anti-thunderbolt duplicate protection and having USB interface.
The technical scheme that the utility model solves its technical problem is: a kind of duplicate protection and with the supply socket of USB interface; Comprise jack body and be located at the power unit in this jack body; Said jack body is provided with the mains switch of the said power unit of break-make; Offer jack on the said jack body; Also be provided with inserted sheet unit corresponding with said jack and that be connected with said power unit in the said jack body; Be provided with anti-thunderbolt protective circuit and overload protecting circuit between said power unit and the said mains switch successively, said power unit also is connected with USB transformation change-over circuit, and said jack body is provided with the USB interface that is connected with said USB transformation change-over circuit.
Further; Said jack is a moral formula jack, totally 8, and be distributed on three faces of said jack body; Wherein two faces are provided with 3 said jacks; Remaining 2 said jacks are arranged on the 3rd face, also are provided with 2 said USB interfaces on the 3rd face, the length and the volume that can dwindle the utility model is set like this, is easy to carry.
Further, be provided with the shutter device with the corresponding position of said jack on the said jack body.
The utility model in use; Mainly provide two kinds to use power mode, the 220V alternating current promptly is provided and 5V is provided light current, 5V light current is that the 220V alternating current by power unit is transformed through USB transformation change-over circuit; The 220V alternating current is that household electrical appliance use through jack; 5V light current is that electronic products such as mobile phone, digital camera, MP3 and MP4 use through USB interface, as long as adopt the usb data line to connect, has enlarged the scope of application of conventional electrical outlet; Give people's life, particularly travelling has brought convenience.In addition; When the utility model in when work, when running into load and surpassing nominal load, will cut off the electricity supply through overload protecting circuit in time stops to transship electrical work; Thereby preventing effectively that supply socket from working under overload causes the damage of supply socket or electric equipment products, uses safer.Perhaps; When running into the thunderbolt of the Nature; Its powerful thunderbolt voltage will be absorbed and in time cut off the electricity supply and in time stop the work of electric equipment products by anti-thunderbolt protective circuit, and powerful additional supply can't get in the electric equipment products, thus the protection electric equipment products; Effectively prevent the damage that the thunderbolt of the Nature brings electric equipment products, use safer.
Because each jack is provided with a shutter device; When jack when not having plug insert to use, the shutter device of each jack is a closed condition, single pin contact pin is the shutter device that can't open jack; Thereby the protection personal safety, carrying is not children's safety.
The beneficial effect of the utility model is: adopt said structure; Be in traditional supply socket, to have additional USB interface; As long as adopt the usb data line to connect the charging that to accomplish electronic product; Enlarged the scope of application of conventional electrical outlet, given people's life, particularly travelling has brought convenience.Simultaneously, also have additional overload protecting circuit and anti-thunderbolt protective circuit, when meeting overload or being struck by lightning, can cut off the electricity supply rapidly in time stops electric equipment products work, has double protection, uses safer.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
With reference to Fig. 1, Fig. 2; A kind of duplicate protection and with the supply socket of USB interface; Comprise jack body 1 and be located at the power unit 2 in this jack body 1; Said jack body 1 is provided with the mains switch 3 of the said power unit 2 of break-make, offers jack 4 on the said jack body 1, and this jack 4 is a moral formula jack; Also be provided with in the said jack body 1 and said jack 4 inserted sheet unit 5 corresponding and that be connected with said power unit 2; Be provided with anti-thunderbolt protective circuit 6 and overload protecting circuit 7 between said power unit 2 and the said mains switch 3 successively, said power unit 2 also is connected with USB transformation change-over circuit 8, and said jack body 1 is provided with the USB interface 9 that is connected with said USB transformation change-over circuit 8.
The utility model in use; Mainly provide two kinds to use power mode, the 220V alternating current promptly is provided and 5V is provided light current, 5V light current is that the 220V alternating current by power unit 2 is transformed through USB transformation change-over circuit 8; The 220V alternating current uses for household electrical appliance through jack 4; 5V light current is that electronic products such as mobile phone, digital camera, MP3 and MP4 use through USB interface 9, as long as adopt the usb data line to connect, has enlarged the scope of application of conventional electrical outlet; Give people's life, particularly travelling has brought convenience.In addition; When the utility model in when work; When running into load above nominal load; Will cut off the electricity supply through overload protecting circuit 7 in time stops to transship electrical work, thereby preventing effectively that supply socket from working under overload causes the damage of supply socket or electric equipment products, uses safer.Perhaps; When running into the thunderbolt of the Nature; Its powerful thunderbolt voltage will be absorbed and in time cut off the electricity supply and in time stop the work of electric equipment products by anti-thunderbolt protective circuit 6, and powerful additional supply can't get in the electric equipment products, thus the protection electric equipment products; Effectively prevent the damage that the thunderbolt of the Nature brings electric equipment products, use safer.
