Description

A kind of DVD player that adopts nonconductor contact electric energy transmission technology

Technical field

The utility model relates to a kind of DVD player, and more particularly, it relates to a kind of DVD player that adopts nonconductor contact electric energy transmission technology.

Background technology

At present, DVD player generally all comprises a Switching Power Supply, is used for the voltage of converting power source, supplies the inner circuit of DVD player 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 DVD player 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 DVD player attaching plug, is prone to flashing in addition, has bigger potential safety hazard.Therefore, designing a kind of DVD player 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 DVD player attaching plug and complementary socket; The utility model provides a kind of DVD player; This DVD player can provide the DVD player power supply method of attachment of the risk of not getting an electric shock, and has therefore enlarged the suitable crowd that can use DVD player.Existing DVD player 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 common DVD machine, 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 DVD player transformer mounting structure, primary coil is placed feeder ear, secondary coil is placed the electricity consumption end.Adopt the DVD player 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 DVD player 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 DVD player 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 DVD player of zero electric shock risk is provided, enlarged the suitable crowd of DVD player, walk away safety.
