Abstract
The utility model discloses a printer which is directly supplied with the power by the case power of a desktop computer. The printer comprises a printer body which is provided with a signal line, the front end of which is provided with a signal plug used for being connected with a signal female on the case; in addition, the printer body is also provided with a direct current supply line, and the end of the supply line is provided with a DC plug, which is spliced with a DC interface female on the case. As the DC plug is arranged at the end of the DC supply line and can be spliced with the DC interface female on the case, the case power can be directly used for supplying power to the printer and switch power supply is not necessary to be arranged on the printer. The printer has very simple structure and relatively low cost.
Description
Technical field:
The utility model relates to the information technoloy equipment technical field, especially relates to a kind of printer of directly powering with the chassis power supply of desktop computer.
Background technology:
Traditional desktop computer printer itself must possess Switching Power Supply, and so that single electric current of 24V or 24V/5V double-current to be provided, also some provides 24V/3.3V double-current.But along with the demand that the desktop computer cost reduces, present its cabinet of many desktop computers is provided with powered by direct current interface female seat, in order to the various interface power devices.Because powered by direct current interface female seat directly connects chassis power supply and 24V, 12V, 10V, 5V voltage can be provided, for example there is the part LCD promptly to supply with the voltage of 24V at present by this powered by direct current female seat, but there is not printer to power in this way as yet, has only printer partly to provide USB signal and 24V electric current simultaneously with " POWERED USBPCICARD ".
POWERED USB pci card is the modified of USB interface, itself has the USB control chip, and an inner socket is arranged in addition, and the connector of the supply lines end of power supply unit inserts this socket, and the direct current of 24V and 12V can be provided.
Though this mode can be applicable to all interface equipments, but this is to install the USB pci card additional on the type computer on the table and reach the power supply purpose, but itself be provided with USB interface on the desktop PC mainboard, to cause cost to rise if install the words of USB pci card in addition additional, Bing makes original USB interface idle.In addition, interface equipment makes USB interface into, and as changing RS232 interface originally into USB interface, the cost of its control chip also will rise, and if idle waste also will be caused in serial ports, the parallel port of not using desktop PC to have originally.Therefore, the popularity rate of this mode is also very low, only is used on some commercial machines (as POS).In addition, this mode can only provide a kind of fixed voltage, and many interface equipments itself need with two kinds of different power voltage supplies.If only use a kind of higher voltage power supply, interface equipment inside also needs to carry out dividing potential drop to obtain different power supplys with the lowering and stabilizing blood pressure chip, causes cost to rise.
Therefore, if can directly power to printer with the direct current interface female seat that is provided with on the cabinet, the Switching Power Supply that then can cancel printer reduces cost, and also can avoid expensive because of what use " POWERED USB PCI CARD " to cause.
The utility model content:
The purpose of this utility model is the weak point that exists at prior art and a kind of printer of directly powering with the computer housing power supply is provided that it needn't be provided with Switching Power Supply on printer, can reduce cost.
For achieving the above object, the utility model comprises printer main body, and this printer main body has a RCA, and the RCA front end is provided with communication signal plug, is used to connect the signal female seat on the cabinet; In addition, printer main body also has the powered by direct current line, and described direct current supply line end is provided with DC plug, and the direct current interface female seat on this DC plug and the cabinet is pegged graft.
RCA is to can be the USB line that drive circuit provides the 5V electric current.
RCA also can be the RS232 line.
The beneficial effects of the utility model are: owing to be provided with the DC plug that can peg graft with direct current interface female seat on the cabinet at direct current supply line end, thereby can directly utilize chassis power supply that printer is powered, Switching Power Supply needn't be set on printer, structure is very simple, the also corresponding reduction of its cost.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is the general structure schematic diagram of the utility model embodiment
The specific embodiment:
Therefore the following stated only for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model.
See shown in the accompanying drawing 1: the utility model comprises a printer main body 10, and this printer main body 10 has a RCA 30, and RCA 30 front ends are provided with communication signal plug 50, is used to connect the signal female seat 80 on the cabinet 100; In addition, printer main body 10 also has powered by direct current line 40, and direct current supply line 40 ends are provided with DC plug 60, and direct current interface female seat 70 power takings that this DC plug 60 is connected with power supply device from the cabinet 100 are to provide the direct current of 24V.
Direct current interface female seat 70 can be positioned at the front or rear panel of cabinet 100, also can be positioned at the back plate of chassis power supply supply; Certainly, direct current interface female seat 70 also can be positioned at the PCI opening on the case backboard, provides 24V electric current by the PCI slot on the mainboard.
RCA 30 is the USB line, and it can provide the electric current of 5V for the drive circuit in the printer main body 10.
Certainly, RCA 30 also can be the I/O interface of RS232 line or other type except being the USB line.
