Abstract
The utility model discloses an integrated transformer which comprises a magnetic core and terminals. The integrated transformer further comprises a PCB. A plurality of copper foil circles which are in etching reserve and in a closed loop circuit mode are distributed on the PCB, a closed loop circuit is formed by each copper foil circle in a spiral mode by using one end of each copper foil circle as a starting point, the starting point and a terminal point of each closed loop circuit are connected with the terminals through internal wires of the PCB, and the magnetic core is sleeved on the PCB provided with the copper foil circles. A scheme design of integrating the copper foil circles on the PCB to replace coils and a winding skeleton is adopted by the integrated transformer, and the integrated transformer has the advantages of being flat, thin and small in size, and is widely applied to flat electronic devices.
Description
Technical field
The utility model relates to transformer, is specifically related to a kind of integrated transformer.
Background technology
At present, in the transformer of prior art, generally all formed by FERRITE CORE, coil and winding skeleton, bulky and be easy to generate electromagnetic interference.And along with the continuous development of electron trade and electronic technology, for better meeting people's needs, electronic equipment is tending towards developing to direction flat, thinner and that volume is little to a certain extent, and obviously, the transformer of existing coil and winding skeleton does not catch up with people's demand gradually.
The utility model content
The problem that the utility model need solve provide a kind of flat, thin, volume is little and adopt the Copper Foil circle is integrated in the integrated transformer that replaces coil and winding skeleton on the pcb board.
To achieve these goals, the utility model is designed a kind of integrated transformer, it comprises magnetic core and terminals, also include pcb board, be distributed with the Copper Foil circle of the closed-loop path of some etchings reservations on the described pcb board, described Copper Foil circle is the closed circuit of starting point spiralization with an end, and starting point is connected with terminals by the inside cabling of pcb board respectively with terminal point, and magnetic core is sleeved on the pcb board that is provided with the Copper Foil circle.
Described pcb board is a multi-layer sheet or forms by the multi-layer sheet more than two is superimposed, be provided with the Copper Foil circle in the plate of every laminate.
As one of preferred version of the utility model integrated transformer, described pcb board is four laminates or six laminates, is provided with the Copper Foil circle in the plate of every laminate.
As two of the preferred version of the utility model integrated transformer, described pcb board is superimposed or two three ply board superimposed compositions by two blocks of two-plies, are provided with the Copper Foil circle in the plate of every laminate.
The rounded helical form of described Copper Foil circle or square spiral shape or oval helical form, the quantity of described Copper Foil circle and the number of turns of spiral according to demand voltage size and decide, the number of plies of described pcb board according to demand voltage size and decide.
The utility model integrated transformer, it comprises magnetic core and terminals, also include pcb board, be distributed with the Copper Foil circle of the closed-loop path of some etchings reservations on the described pcb board, described Copper Foil circle is the closed circuit of starting point spiralization with an end, starting point is connected with terminals by the inside cabling of pcb board respectively with terminal point, and magnetic core is sleeved on the pcb board that is provided with the Copper Foil circle.The utility model integrated transformer has omitted coil and winding skeleton, adopts the Copper Foil circle is integrated in the integrated transformer that replaces coil and winding skeleton on the pcb board, and is flat, thin, volume is littler, and its height can be accomplished to be widely used in the electronic equipment of flat below the 15mm.
