A kind of power distributor with USB interface
The utility model relates to a kind of power supply device, especially a kind of power distributor with USB interface.
In daily life, along with developing rapidly of electronics technology industry, in a lot of electronic equipments, all use USB device, in these miniaturization of electronic products and integrated development process, have power supply and data transport functions concurrently and can realize that the general-purpose serial bus USB interface of hot plug is adopted by increasing electronic product, mobile phone for example, digital camera, MP3, MP4 and PSP etc., wherein a lot of these series products can be powered by USB interface, carry out work or be battery charge, at this moment, often need these electronic products are connected with other electrical equipment that have USB interface by the USB connection cable, such as the power source special transducer of computer or band USB interface, this has no doubt solved the normal use of these electronic products,, going on business or whilst on tour, seldom carrying computer or look for computer to charge specially, so brought a lot of inconvenience to people.For carry the connection cable that is provided with USB port simultaneously and have USB port other electrical equipment also be a very inconvenient thing, if forget sometimes, will directly can have influence on normal use.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of power distributor with USB interface is provided, people can be when using common mains ac power supply, only need carry and the corresponding USB charge power supply of electronic product line such as mobile phone, just can use the USB power source charges, make the convenient and swift of charging process change, and make easily, cost is lower.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of power distributor with USB interface, comprise housing and the electrode contact that is installed in enclosure interior, described housing is made of upper shell and lower house, is divided into two cavitys in enclosure interior, at least one single-phase three-wire supply socket is installed in one cavity, the charging integration module is installed in another cavity.
Wherein, described charging integration module is the power supply adaptor that core-type transformer constitutes, or the electronic power supply adapter of being made up of electronic component.
Wherein, described charging integration module comprises circuit board, mains switch, charged state indicator light, USB interface, electric component group.
Wherein, described charging integration module has input and output, and input is connected with the single-phase three-wire socket by connector, and the both positive and negative polarity of output is connected with both positive and negative polarity in the usb socket respectively.
Wherein, described panel is provided with the hollow slots corresponding respectively with single-phase three-wire supply socket, charged state indicator light and USB interface.
Wherein, be provided with the miniature electronic rectifier in the described housing, its output is connected with USB interface.
The beneficial effects of the utility model are: (1) user only need be with USB charge power supply line, promptly can finish charging, not need to carry charger, the more convenient and quicker that charging process is become in the occasion that does not have computer, for the user has brought facility, the worry of also having eliminated burden fully and having forgotten; (2) the utility model is simple in structure, and is easy to make, and critical piece is all made easily and bought, and cost is lower; (3) the utility model is applied widely, has enlarged the range of application of supply socket, is applicable to places such as family, office, has good society and economic benefit; (4), can protect mobile phone can when charging, not damage by the pressure limiting of miniature electronic rectifier rectification.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing acceptance of the bid keep the score state as follows: 1---housing; 2---the single-phase three-wire supply socket; 3---USB interface; 4---the charged state indicator light; 5---mains switch.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, the utility model is a kind of power distributor with USB interface, comprise housing 1 and the electrode contact that is installed in enclosure interior, described housing is made of upper shell and lower house, be divided into two cavitys in enclosure interior, at least one single-phase three-wire supply socket is installed in one cavity, the charging integration module is installed in another cavity.Described charging integration module is the power supply adaptor that core-type transformer constitutes, or the electronic power supply adapter of being made up of electronic component.Described charging integration module comprises circuit board, mains switch 5, charged state indicator light 4, USB interface 3, electric component group.Described charging integration module has input and output, and input is connected with the single-phase three-wire socket by connector, and the both positive and negative polarity of output is connected with both positive and negative polarity in USB interface 3 sockets respectively.Described USB interface 3 output voltages are 5V～9V, and electric current is 300mA.Can also increase by one grade to the USB interface output voltage, can fail the voltage of 15V～24V.Housing 1 is provided with and single-phase three-wire supply socket 2, charged state indicator light 4 and the corresponding respectively hollow slots of USB interface 3.Be provided with the miniature electronic rectifier in the described housing 1, its output is connected with USB interface 3.
The utility model only need be connected power distributor in use with mains supply, can use.The electronic product of band USB port, for example mobile phone, digital camera, MP3, MP4 etc., only an end of USB connection cable need be connected with the input of mobile phone, digital camera, MP3, MP4, the other end is connected with USB port in the supply socket, and opens described mains switch they are charged or operate as normal.The utility model has been realized USB interface integrated in common AC power socket with ripe, simple structure and lower cost, can be installed on family, office, public place etc. widely locates, for using the electronic product and the equipment of USB interface power supply, needs provide convenience, and when needs use, only need carry the power distributor that is provided with USB port and just can from the common supply socket in other places, obtain required power supply supply at any time.
Obviously the foregoing description is not to restriction of the present utility model, and above-mentioned a kind of power distributor with USB interface can also have other many variations.Though gone through the utility model in conjunction with above-mentioned example, some that should be understood that professional person in the industry can expect apparently are identical, and alternative scheme all falls within the protection range that the utility model claim limited.
