It is connected to two groups of transformers, described binding post and be connected with conductive copper sheet between transformer described in two groups.
By adopting technique scheme, two groups of transformers are set, two groups of transformers are respectively provided with the effect of boosting, improve
The power of inverter；When being powered, due to being connected by conductive copper sheet between binding post and transformer, compared to directly leading to
Cross the situation that the wire of printing on pcb board is connected, conductive copper sheet has larger sectional area, according to the law of resistance, conductive copper sheet
Resistance be significantly smaller than on pcb board printing wire resistance, therefore feeder ear also subtracts therewith to the voltage drop between transformer
Little, thus improve power supplying efficiency；Conductive copper sheet directly connects simultaneously, improves inversion conversion efficiency, is meeting current needs
In the case of, more convenient to operate and security is higher.
The utility model is further arranged to：The width of described conductive copper sheet is 3mm-4mm and thickness is 0.8mm-1mm.
By adopting technique scheme, conductive copper sheet can preferably reduce the voltage to transformer for the feeder ear
Fall, makes conductive copper sheet have stronger current carrying capacity simultaneously, also convenient in wiring.
The utility model is further arranged to：The width of described conductive copper sheet is perpendicular with described pcb board body.
By adopting technique scheme, in wiring, the area that conductive copper sheet occupies pcb board is less, will not hamper
The installation of other components and parts, simultaneously in convenient with the connection of transformer and bigger with the contact area of air, radiating effect
More preferably.
The utility model is further arranged to：Interface is offered on described binding post.
By adopting technique scheme, the input line of load input terminal is plugged in interface and can achieve and inverter
Connection.
The utility model is further arranged to：Described binding post is vertically distributed with multilayer.
By adopting technique scheme, the input line of load input terminal is more firm with the connection of binding post, simultaneously
Further reduce voltage drop on binding post for the load input terminal, thus further increasing power supplying efficiency；And due to connecing
Line terminals distributed multilevel, has gap between adjacent binding post, convenient binding post radiating.
The utility model is further arranged to：The end of described binding post is in that circular arc is arranged.
By adopting technique scheme, decrease the phenomenon that point discharge is occurred on binding post, make load input terminal
Safer with the connection of inverter.
In sum, the utility model has the advantages that：
First, by arranging conductive copper sheet, decreasing feeder ear and also reduce therewith to the voltage drop between transformer, thus
Improve power supplying efficiency；Conductive copper sheet directly connects simultaneously, improves inversion conversion efficiency, is meeting the situation of current needs
Under, more convenient to operate and security is higher；
Second, by binding post is set to multilayer, further reducing electricity on binding post for the load input terminal
Pressure drop, thus further increasing power supplying efficiency, radiating effect is more preferable simultaneously.
Brief description
Fig. 1 is the structural representation of the present embodiment；
Fig. 2 is the A portion enlarged drawing of Fig. 1.
In figure：1st, PCB body；2nd, binding post；21st, interface；3rd, conductive copper sheet；4th, transformer.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
A kind of pcb board of novel inverter, as depicted in figs. 1 and 2, pcb board body 1 is provided with binding post 2, terminals
Son 2 is used for being connected with load input terminal, and binding post 2 is vertically evenly distributed with multilayer, between leaving between adjacent two layers
Gap；The end of binding post 2 is in that circular arc is arranged, thus decreasing the phenomenon that binding post 2 occurs point discharge, improves negative
Carry the security that input is connected with inverter；Interface 21 is had on binding post 2, interface 21 is positioned close to terminals
