Abstract
The utility model relates to a display using the non-conductor contact power transmission technology. Based on the principle that the energy can be transferred through the magnetism of a transformer, the transformer structure of a switching power supply in an existing display is changed, i.e. a primary coil is arranged on a power supplying terminal, and a secondary coil is arranged on a power using terminal. The display provided by the utility model comprises the power supplying terminal and the power using terminal, wherein the power supplying terminal comprises an E-shaped magnetic core or a magnetic core shaped like a left square bracket, the primary coil wound on the magnetic core, and an AC power supply connected with both terminals of the primary coil. The power using terminal comprises an inverted E-shaped magnetic core or a magnetic core shaped like a right square bracket, the secondary coil wound on the magnetic core, and a load connected with both terminals of the secondary coil, wherein the load includes a display switching power supply module and the display, which are positioned on the power using terminal. After the power supplying terminal and the power using terminal are combined, a nearly complete square magnetic core or a magnetic core nearly shaped like two squares vertically stacked together is formed by the magnetic cores of the power supplying terminal and the power using terminal, so that an enclosed magnetic line channel can be formed by the magnetic cores of the power supplying terminal and the power using terminal; and therefore, the display can begin normal work.
Description
Technical field
The utility model relates to a kind of display, and more particularly, it relates to a kind of display that adopts nonconductor contact electric energy transmission technology.
Background technology
At present, display generally all comprises a Switching Power Supply, is used for the voltage of converting power source, supplies the circuit of display interior to use.Switching Power Supply is except control circuit, and main transducing head is a switch transformer, and the structure of transformer all is on the magnetic conduction construction that magnetic core combines, to twine primary coil and secondary coil is made.Thisly comprise display elementary, secondary integrated switched power transformer, supply socket must be installed so that power supply to be provided.The existence of socket, plug, the possibility that promptly has bare exposed conductor to get an electric shock when plug display power supply plug, is prone to flashing in addition, has bigger potential safety hazard.Therefore, designing a kind of display that does not need the employing nonconductor contact electric energy transmitting of plug and socket of power source, is the present technical issues that need to address.
The utility model content
In order to overcome the deficiency that in use has bigger potential safety hazard of existing display power supply plug and complementary socket; The utility model provides a kind of display; This display can provide the display power supply method of attachment of the risk of not getting an electric shock, and has therefore enlarged the suitable crowd that can use display.Existing display will make it start working; Must be connected on the 220V civil power; The dull-witted especially consciously or old man not too easily that takes action of a lot of old men; Also have child when using the attaching plug of existing regular display, have bigger electric shock risk, the utility model has given satisfactory solution to this problem.
The utility model solves the technical scheme that its technical matters adopted: at first be to have utilized transformer magnetic to transmit the principle of energy, changed existing display transformer mounting structure, primary coil is placed feeder ear, secondary coil is placed the electricity consumption end.Adopt the display of nonconductor contact electric energy transmitting, comprise feeder ear and electricity consumption end, feeder ear comprises " ［ " type or " E " font feeder ear magnetic core and be wrapped in the primary coil on the feeder ear magnetic core, primary coil two ends connection AC power.The electricity consumption end comprises " ］ that adapts to feeder ear " type or anti-" E " type magnetic core and be wrapped in the secondary coil on the electricity consumption end magnetic core, the secondary coil two ends connect load, and load is exactly switch inside energy supply control module and display remaining part.Feeder ear is with after the electricity consumption end structure combines; Feeder ear magnetic core and electricity consumption end magnetic core constitute approximate complete " mouth " font or " day " font magnetic core; Feeder ear magnetic core and electricity consumption end magnetic core constitute closed magnetic line of force passage; Add that the primary and secondary coil groups synthesized complete transformer, so just order has changed the display work of structure, and has reached the purpose that does not need plugs and sockets.
The beneficial effect of the utility model is: when a kind of display of zero electric shock risk is provided, enlarged the suitable crowd of display, walk away safety.
