The vertical-type flat-plate transformer has the advantages of small occupied area on a printed circuit board (PCB), low welding resistance and good heat-dissipating effect.
Description
Technical field
The utility model relates to a kind of transformer, relates in particular to a kind ofly can stand up the formula flat-plate transformer on pcb board.
Background technology
Flat-plate transformer is because the current density height, leakage reactance is little, the Switching Power Supply that is fit to very much low-voltage and high-current, wherein Chang Yong Copper Foil formula flat-plate transformer is generally the installation of plane formula magnetic core, whole transformer device structure is flattening, flat structure occupation space on pcb board is just relatively large, and the height space underutilization.The pin of Copper Foil formula flat-plate transformer uses special-purpose leg or Copper Foil to be welded on the PCB in the bottom of transformer, and bigger welding impedance is arranged, because electric current has passed through PCB, needs the PCB cabling and the heat radiation of broad.
The utility model content
The technical problems to be solved in the utility model is at the above-mentioned defective of prior art, and a kind of formula that stands up flat-plate transformer that the pcb board area is little, reduce welding impedance, good heat dissipation effect that takies is provided.
The utility model solves above-mentioned technical problem by the following technical programs: a kind of formula flat-plate transformer that stands up, comprise magnetic core, winding, described winding is the copper bar winding that is arranged in the magnetic core, described copper bar winding extends three pins to the magnetic core outside, and the copper bar winding also is connected with the output copper bar that is provided with power tube.
Described three pins are respectively and the 3rd pin of exporting first pin that copper bar is connected and second pin, being connected with pcb board.
Magnetic core is provided with the radiator that is connected with the copper bar winding outward, and radiator and described three pins lay respectively at the not ipsilateral of magnetic core.
Described radiator and copper bar winding are structure as a whole.
Described the 3rd pin is that its free end flushes with the magnetic core bottom surface to the pin of magnetic core bottom surface bending.
Described copper bar winding is made up of two the first parallel copper bars and second copper bar, and first copper bar is drawn first pin, and second copper bar is drawn second pin, and first copper bar and second copper bar are all drawn and formed the 3rd pin.
Two output copper bars that are connected with second copper bar with first copper bar respectively are set.
Described copper bar winding and output copper bar are structure as a whole.
First pin of described copper bar winding is detachably fixedlyed connected with the output copper bar respectively with second pin.
The output copper bar stretches out and is useful on the bending edge of heat radiation.
The utility model adopts the copper bar winding, the copper bar winding is drawn three pins simultaneously, therefore needn't be as existing Copper Foil formula flat-plate transformer, magnetic core is lain on the pcb board, be installed on the pcb board and magnetic core revolved to turn 90 degrees, after the rotation, the copper bar winding is drawn just corresponding with the pcb board welding of three pins, magnetic core revolves and turn 90 degrees for wattage transformer, has made full use of height space, has saved the area that takies on pcb board; And use copper bar that pin is directly drawn, can connect the output copper bar that is provided with power tube, reduced the welding impedance.And use the copper bar winding to do winding, inner winding heat radiation is more prone to.
Copper bar winding and radiator are integrated, and thermal resistance is littler, and need not consider to install.
The output copper bar is used for being connected between power tube and the copper bar winding pin, the metal utmost point of power tube is welded direct on the output copper bar, bonding area is far longer than the bonding area of pin, the welding impedance and the impedance of pin own of power pin have been reduced, reduce the stray inductance of pin, export copper bar simultaneously and can be used as radiator heat-dissipation.
The copper bar winding is two parts with the output copper bar, and actual processing is convenient in this separate type design.
A plurality of pin of the present utility model all is that self-clinching stud is a kind of common connected mode with self-clinching stud output, is suitable for electric current and connects; And connect reliable.
