Background technology
At present, when DC-DC secondary power supply transformer primary secondary operating currents are larger (electric current 20-30A), it is necessary to by transformation
Device original vice-side winding is designed to that copper foil back-gluing band welds the mode of lead-out wire again.Because the position of primary and secondary side lead-out wire by
Limit, then the generous size of lead-out wire can be also limited, therefore, it is necessary to by the way of copper bar is drawn in welding.
However, because magnetic core center pillar is mostly circle, cause the bad determination in position for drawing copper bar, complex process.Winding copper
Paper tinsel needs first to be cut, chamfering and pre- soldering；Draw copper bar be also required to first to be cut, chamfering and pre- soldering, then make again
Two of copper foil is welded to centre position by copper bar is drawn with flatiron.So, the pin distribution of final transformer is irregular,
So as to cause the design of pcb board that matches with product and manufacture difficulty larger, moreover, when transformer inserts pcb board, pin pair
Position is more difficult.
In addition, transformer winding structure Central Plains secondary couples not close, whole complex process, realized entirely by human hand.Solder joint
Easy heap tin, produces tin point, rosin joint etc..Not only inferior quality, and time-consuming, and production efficiency is not high, is not suitable for high-volume
Production.
