Description
Technical field
The utility model relates to TV tech system, in particular to a kind of power supply unit applied to flat panel TV.
Background technique
Flat panel TV competition, each producer all make great efforts to look for differentiation in ultra-thin television design.Traditional tv electricity
Source module is fixed on the metal backing of television internal using the power panel comprising ac high-voltage alive circuit, due to needing to consider
To rear cover fire safety distance and to the safety electric clearance distance and power supply thickness of bare metal it is higher, so electric
Can be thicker depending on rear cover, cause whole set of television be difficult to further do it is thin.
Summary of the invention
The technical problem to be solved by the utility model is to proposing a kind of power supply unit applied to flat panel TV, protecting
On the basis of demonstrate,proving TV performance, whole set of television thickness is further decreased.
The utility model solves technical solution used by above-mentioned technical problem:
Power supply unit applied to flat panel TV, comprising: adapter, socket, clamp circuit, signal processing and backlight drive
Power supply circuit；The adapter is arranged outside television set, pluggable；The socket, clamp circuit, signal processing and backlight are driven
Dynamic power supply circuit is arranged on the metal backing of inside television, and the jack of the socket protrudes from television enclosure；When passing through
When the socket couple in adapter, the input terminal of the adapter connects line voltage, and output end connects clamper electricity by socket
The input terminal on road；The output end connection signal processing of the clamp circuit and backlight drive power supply circuit.
As advanced optimizing, the socket includes 4 jacks, and two of them jack is accessed to by the positive terminal of socket
The anode of adapter output voltage, other two jack access to the cathode of adapter output voltage by the negative pole end of socket.
As advanced optimizing, the clamp circuit includes fuse, diode, resistance and capacitor；The socket is just
The extreme cathode that diode is connected by fuse, the plus earth of diode；Two are connected to after the resistance and capacitor series connection
Between the anode and cathode of pole pipe.
The beneficial effects of the utility model are: passing through the design of the power supply unit, using adapter as an independent device
Part is placed on outside TV, can be plugged in respective socket；By respective socket, clamp circuit, signal processing power supply and backlight
Driving power supply circuit is placed on television internal, and these components are secondary side low-voltage circuit, is not necessarily to larger safety electric clearance distance,
So rear cover thickness can be reduced by being mounted on metal backing, to be further reduced TV thickness, product competitiveness is promoted.
Detailed description of the invention
Fig. 1 is the power supply unit structural block diagram in the utility model；
Fig. 2 is the structural schematic diagram of socket；In figure, 1,2,3,4 be the jack of socket；
Fig. 3 is clamp circuit schematic diagram；In figure, F1 is fuse, and D1 is diode, and R1 is resistance, and C1 is capacitor.
Specific embodiment
The utility model is directed to a kind of power supply unit applied to flat panel TV, on the basis for guaranteeing TV performance
On, further decrease TV thickness.
As shown in Figure 1, the power supply unit in the utility model includes adapter, socket, clamp circuit, signal processing and back
Optical drive power supply circuit；The adapter is arranged outside television set, pluggable；The socket, clamp circuit, signal processing and
Backlight drive power supply circuit is arranged on the metal backing of inside television, and the jack of the socket protrudes from television enclosure；
When passing through the socket couple in adapter, the input terminal of the adapter connects line voltage, and output end is connected by socket
The input terminal of clamp circuit；The output end connection signal processing of the clamp circuit and backlight drive power supply circuit.
The utility model is placed on adapter as an independent device outside TV, can be inserted in respective socket
It pulls out；Respective socket, clamp circuit, signal processing power supply and backlight drive power supply circuit are placed on television internal, and these portions
Part is secondary side low-voltage circuit, is not necessarily to larger safety electric clearance distance, so rear cover thickness can be reduced by being mounted on metal backing
Degree, to be further reduced TV thickness.
In specific implementation, adapter is used to AC-input voltage 220V being converted to direct current 19V voltage, and 19V voltage is defeated
Out to socket；Wherein, for socket structure schematic diagram as shown in Fig. 2, comprising 4 jacks, jack 1 and jack 2 are being connected to 19V power supply just
Pole, jack 3 and jack 4 are connected to the cathode of 19V power supply, and power supply through-current capability is improved by way of porous patch, is guaranteed simultaneously
Grafting reliability.
Clamp circuit is as shown in figure 3, the anode of socket 19V power supply is connected to the cathode of diode D1 by fuse F1, and two
It is connected between the anode and cathode of diode D1 after the plus earth of pole pipe D1, resistance R1 and capacitor C1 series connection；Wherein insure
Silk mainly plays overcurrent protection, and diode D1 plays the role of inhibiting surge voltage when adapter grafting, resistance R1 with
Capacitor C1 forms filter network, can inhibit surge voltage when adapter grafting；Clamp circuit export Vo to signal processing and
The power supply of backlight drive power supply circuit.
