Abstract
The utility model discloses an LED TV (Light Emitting Diode Television) transformer capable of reducing eddy current loss, which comprises a coil framework on which a coil winding is wound, and a magnetic core which is inserted into the coil framework. The top and the bottom of the coil framework are covered by a framework shell. The top of the framework shell is covered by an aluminum sheet. A raised part with a shape as shown by the accompanying drawing is arranged on the framework shell. Slots are arranged on the two sides of the raised part. The aluminum sheet is inserted into the slots. By changing the framework shell, adding the slots for inserting the aluminum sheet and placing an aluminum plate at the top of the transformer, the eddy current loss of a power supply is reduced and the electromagnetic interference is reduced.
Description
Technical field
The utility model relates to a kind of transformer, particularly is applied to the transformer on great power LED TV.
Background technology
At present, at present, the powerful television set of LED TV is much to adopt metal shell, and required thickness is thinner, loss of power power often can occur larger, and electromagnetic interference (EMI) is difficult to control.Principle is that the power of transformer on high-power LED TV power supply is larger, and with the housing of TV set close together of metal material, will produce like this and resemble the identical eddy current effect of electromagnetic oven, near the eddy current transformer and shell generation eddy current loop, thereby make shell hot, source power loss increases.Due to the improper increase of power, cause electromagnetic interference to strengthen simultaneously.
The utility model content
Technical problem to be solved in the utility model just is to provide a kind of LEDTV transformer that reduces eddy current loss, reduces the loss of power, reduces electromagnetic interference.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of LEDTV transformer that reduces eddy current loss, comprise the coil rack that is wound with coil windings and the magnetic core that inserts coil rack, it is characterized in that: described coil rack top and bottom are by the capping of skeleton shell, and described skeleton cover top portion is coated with aluminium flake.
As preferably, described coil rack comprises limit, the left and right sides and is vertical at single line loop pillar between limit, left and right sides middle part, two ends, described coil column left and right are respectively equipped with a coil groove, coil windings is wrapped in the coil groove, described magnetic core have two and be " " font, the protuberance at magnetic core middle part inserts in coil column E.
As preferably, described skeleton shell be provided with " projection of [" shape, this projection dual-side is provided with slot, aluminium flake is plugged in described slot.
As preferably, be wound with insulating tape on described coil rack, insulating tape is fastened magnetic core and skeleton shell on coil rack.
The utility model increases by the change of skeleton shell the slot that inserts aluminium flake, places an aluminium sheet at the top of transformer, and the eddy current loss of power supply is reduced, and reduces simultaneously electromagnetic interference.
The beneficial effects of the utility model are: install aluminium flake additional by the transformer top, the regional area temperaturing lifting abnormality of housing of TV set is disappeared, and the EMI effect of complete machine obtained remarkable improvement, reached national standard.
