Therefore arranged by lower circuit board, inductance mounting plate, middle circuit board, upper circuit board laminate, it is greatly improved Space utilization rate improves the integrated level of equipment, and will have DCDC power conversion circuit that underlying lower circuit board is arranged, Due to being high-tension circuit above lower circuit board, and DCDC power conversion circuit belongs to low-voltage circuit, therefore passes through setting barricade Between lower circuit board and middle circuit board, using the insulating effect of barricade, the stability of equipment operation is improved, and is connected Mode then uses connector to be connected to upper circuit board and lower circuit board across middle circuit board, optimizes the layout of route, leads to Cross the vehicle-mounted OBC charger that Highgrade integration is realized in flat laminated circuit board setting.By vertical piece be arranged in inductance and Between lower circuit board, using stringer board isolation from the interference of inductance, and insulating part is set in lateral piece, to further increase The operation stability of equipment, and using being provided with support column on the barricade of fixed setting again, it is further right by support column Upper circuit board and middle circuit board, to optimize mounting structure and device layout.By the way that conductive sheet is arranged in middle circuit board Between high-voltage charging power conversion circuit, and conductive sheet is connected between circuit board and lower circuit board, and is therefrom circuit The outside of plate passes through, and the adjustment of current direction is easily carried out using the conductive sheet of optimization layout, and insulation sleeve can be improved equipment Operation stability.
Also, by being provided with transformer and condenser network on the opposite two sides of circuit board, transformer is that setting is being held It receives in slot and filled with casting glue, and is detrimental to carry out multiple capacitors relative to the table side end face of transformer in circuit board Arrangement, therefore on the table side end face of the capacitor plate by the way that multiple capacitors to be arranged in independent one piece, and on capacitor plate It arranges line related, then by capacitor plate and welding circuit board, then realizes the device optimization of optimization transformer and capacitor Arrangement improves device space utilization rate.Electrical connection hole, coil connecting hole is passed through by attachment screw to connect with the first mounting hole, To facilitate the installation of transformer to be connected and fixed.Capacitor plate is limited by attachment screw and is fixed, is mentioned in Reflow Soldering process The precision and stabilization of height welding.Installation fixation is carried out in face of connecting plate by the installation end of holding tank, and not only can be in pedestal Support column can also be arranged on installation end face in upper setting support column, install to circuit board by different support columns solid It is fixed, to improve the Assembly stability of equipment.Holding tank can not only carry out heat conduction and heat radiation to transformer by casting glue, and also The outer wall switch tube that can use holding tank carries out heat conduction and heat radiation, and keeps pressure holding using pressure holding piece and tabletting switch tube Power improves heat transfer efficiency to optimize the radiator structure arrangement of charger.
And by the way that inductance to be arranged on the bottom side end face of PFC inductance plate, and inductance is arranged in holding tank, PFC inductance plate lid is closed outside holding tank, then circuit board cover is closed above the longitudinal direction of PFC inductance plate, and utilizes and is electrically connected Connected components are connected electrically between PFC inductance plate and circuit board, are laid out by the laminated circuit board of longitudinal stereoscopic, are then realized optimization The preferred arrangement of device improves device space utilization rate.By the setting of electric connecting sheet and electric binding post, so that assembly can be improved Convenience and assembly redundancy, in addition also using through setting handle hole, it is convenient in handle hole to attachment screw Carry out operation installation.
In addition, each circuit module of orderly setting of arrangement and circuit module by laminated circuit board, so that power Flow direction successively passes through AC port filter circuit, PFC power change switch tube assembly, PFC bus electrolytic capacitor and high-voltage charging After power conversion circuit, power flow can be exported from high voltage direct current port filter circuit or be exported from DCDC power conversion circuit, i.e., Power flow is transmitted again to lateral left part from lower left quarter toward lateral right part, upper transverse portion, and is pacified from longitudinally lower inductance is located at Loading board enters, and then successively circuit board transmits up, then down, finally can therefrom circuit board output or defeated from lower circuit board Out, the flow direction of power flow reduces the mutual interference of circuit after optimization, improves the operation stability of equipment.
