Abstract
The utility model discloses a 12V USB interface device for the POS machine main set, and is capable of driving external equipment directly and saving the resources in an effective way. The device consists of a USB power supply control loop and a USB interface loop; wherein, the output end of the USB power supply control loop is connected with the working electrical source input end of the USB interface loop; the 12V power supply is connected directly with the USB interface end of the USB interface loop; the utility model can realize the purpose of saving resources through the means that the USB interface is loaded with the 12V voltage, the POS machine main set is connected with the external equipment via the USB interface and the 12 power supply of the USB interface can directly drive the external equipment.
Description
Technical field
The utility model relates to a kind of USB interface loop, particularly a kind of 12VUSB interface arrangement of POS machine host.
Background technology
The abbreviation of POS (point of sells) point of sale refers to the place of paying the bill for goods purchased in the market in general sense.Generally speaking, POS refers to the counter transaction system that automatic supermarket uses, and utilizes scanner reading tag and bar code, electronic cash register, and utilizes other specialized equipment to write down the income of this point of sale.The POS machine refers to the terminating machine that this process is used.
At present, the POS machine uses very extensively on the market, no matter is industries such as finance, oiling, telecommunications, especially after the use crowd of IC-card increases, greatly facilitates holder's use.
Yet, existing P OS machine all is to be connected between USB interface and the external unit by standard usually, but because the USB interface of standard has only the voltage of 5V, can't be used for directly driving external unit, external unit also needs to drive by alternate manner, cause the complicated more of total system, wasted resource simultaneously.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of 12VUSB interface arrangement of POS machine host, can directly drive external unit, has effectively saved resource.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of 12VUSB interface arrangement of POS machine host, it is characterized in that, it comprises a USB power control loop and a USB interface loop, the output terminal of described USB power control loop connects the working power input end in USB interface loop, and the 12V power supply directly inserts the USB interface end in the USB interface loop.
The 12VUSB interface arrangement of a kind of POS machine host of the present utility model, by on USB interface, loading the voltage of 12V, when the POS machine host is connected with external unit by USB interface, can directly drive external unit by the 12V power supply on the USB interface, save resource widely, realized the purpose of this utility model.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
As shown in Figure 1, a kind of 12VUSB interface arrangement of POS machine host, it comprises a USB power control loop 1 and a USB interface loop 2.
USB power control loop 1 is made of resistance R 10, R11, R12, R13, capacitor C 17, C18, C19 and power control switch U3; Resistance R 12, R13 one end insert in the control circuit of POS machine after connecting capacitor C 18, C19 respectively, and the other end of capacitor C 18, C19 is connected to each other back ground connection; The other end of resistance R 12, R13 connects 2,3 pin that insert power control switch U3 behind resistance R 10, the R11 respectively, connects after the other end of resistance R 10, R11 is connected to each other+the 2.5V power supply; Connect+5VSUS after 1,4 pin of power control switch U3 are connected to each other, 8 pin of power control switch U3 are capacitor C 17 and ground connection respectively, and 7 pin of the other end of capacitor C 17 and power control switch U3 are connected to each other, and connect then+5VSUS; 8 pin of power control switch U3 insert described USB interface loop 2.
When USB interface CN3 was connected to external unit, the 12V power supply of last 6,7 pin of interface CN3 just can directly drive the work of external unit.
In the utility model, the model of the power control switch U3 in the USB power control loop 1 is CN2026ISTR, and it can supply two-way USB interface loop, and another USB interface loop, road can be connected 5 pin of power control switch U3; The structure in another USB interface loop, road is identical with described USB interface loop 2, and 6,7 pin of its USB interface are by fuse connection+12V power supply.
More than show and described ultimate principle of the present utility model and principal character and advantage thereof.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
