Abstract
A signal power-line and special socket for LCD includes a power line, a signal line and a LCD socket connected with the input end of the LCD display; wherein, the signal line and the power line are combined as an integrated structure. The inside part of the signal-power line is isolated and shielded and the input end of the signal power-line are respectively provided with a power input joint and a display input joint. The output end is a head. The LCD socket is arranged on a host housing. The power of the LCD socket is connected with the host power. The diad signal power-line of the utility model can not only simplify the connecting relationship between the host and the display, but also reduce the whole cost of the product. More importantly, the utility model has also reduced the electromagnetic radiation of the on-off frequency of a power switch tube to the display after canceling a power adapter and simultaneously reduced the influence of the power switch tube to the odd harmonic of electric network.
Description
Technical field
The utility model relates to a kind of power supply signal line and socket thereof, and especially a kind of incorporate LCD display is with signal power supply line and private jack.
Background technology
At present, the input of computer LCD display has two lines: holding wire and power line.For the LCD display of built-in power supply adapter, power line is for exchanging the AC220V line.For the LCD display of external power supply adaptor, the input voltage of power line is direct current (about 12V), and it is by power supply adaptor, becomes required voltage exchanging the AC220V voltage transformation.But the both needs power supply adaptor, has increased the space that a kind of burden, the particularly latter have taken desktop to LCD display undoubtedly.The power supply switch tube switching frequency of power supply adaptor is bigger to the display electromagnetic radiation, also produces the odd harmonic to electric network influencing.
Summary of the invention
The purpose of this utility model is to provide a kind of LCD display with signal power supply line and private jack, two lines are united two into one, reduce independently line, the cancellation power supply adaptor, private jack is set directly on the main frame, the input interface of LCD has only one, thereby makes the integration of LCD display input, and the line operation is directly oversimplified.
Another purpose of the present utility model is to provide a kind of LCD display with signal power supply line and private jack, replace power supply adaptor with ball bearing made using, not only reduce product cost, and significantly reduced the influence of electromagnetic radiation, and the power supply switch tube odd harmonic is to the influence of electrical network display.
The purpose of this utility model is achieved in that a kind of LCD display is with signal power supply line and private jack, it comprises LCD display power line that input connects, holding wire and LCD socket, wherein said holding wire and the power line structure that is integrated, this signal power supply line internal insulation shielding, its input has the power supply input adapter respectively and shows input adapter, output is a stature, and the LCD socket is arranged on the housing of main frame.
The power supply of described LCD socket connects host power supply.
The power supply of described LCD socket and the LCD power supply between the host power supply provide circuit, and this circuit connects transformer by the big operating current switch triode output that connects host power supply, transformer by big electric current Schottky Rectifier to LCD socket power end.
The two-in-one signal power supply line of the utility model can not only make the annexation between main frame and the display simplify greatly, and the whole cost of product is reduced, after the more important thing is the cancellation power supply adaptor, also reduced of the electromagnetic radiation of the switching frequency of power supply switch tube, also reduced the influence of power supply switch tube simultaneously the odd harmonic of electrical network to display.
Description of drawings
Fig. 1 is the utility model structure and connection diagram;
Fig. 2 is the utility model power circuit partial circuit schematic diagram.
Embodiment
Referring to Fig. 1, the utility model is a kind of LCD display signal power supply line 1 and private jack 2.At the LCD display input, the holding wire that is connected in main frame shows signal jack 4 is constant, and power line is then directly supplied with by the power supply on the main frame.
Holding wire 11 and power line 12 structure that is integrated wherein, this signal power supply line 1 internal insulation shielding, its input has power input plug 13 respectively and shows input plug 14, and output is a stature, and LCD socket 2 is arranged on the housing 3 of main frame.
The power supply of LCD socket 2 connects host power supply.Provide circuit at the power supply of LCD socket 2 and the LCD power supply between the host power supply.
As shown in Figure 2, because ATX, uATX, ATX12V power supply output dc voltage in the general Desktop PC main frame comprise+5V-5V ,+12V ,-12V ,+3.3V etc.Wherein ,+the 12V electric power outputting current is between 4A--13A.If as its load,, only need increase LCD display 3--4A to its electric current and get final product in order to guarantee original effect.This circuit meets transformer T1 by big operating current switch triode Q1, the Q2 output that connects host power supply, and transformer T1 is by big electric current Schottky Rectifier D1, D2, draws the power end of the LCD socket 2 of two power lines to the host shell 3.
During connection, jack of 5 need of LCD display end, single line, and on host shell, holding wire plug 14 is inserted on the original signal delivery outlet 4, power-line plug 13 be inserted in+12V power output socket 2 on.
Claims (3)
1, a kind of LCD display is with signal power supply line and private jack, it comprises LCD display power line that input connects, holding wire and LCD socket, it is characterized in that: described holding wire and the power line structure that is integrated, this signal power supply line internal insulation shielding, its input has the power supply input adapter respectively and shows input adapter, output is a stature, and the LCD socket is arranged on the housing of main frame.
2, LCD display is characterized in that: the power supply connection host power supply of described LCD socket with signal and power line according to claim 1.
3, as LCD display as described in the claim 2 with signal and power line, it is characterized in that: the power supply of described LCD socket and the LCD power supply between the host power supply provide circuit, this circuit connects transformer by the big operating current switch triode output that connects host power supply, transformer by big electric current Schottky Rectifier to LCD socket power end.
