The bobbin bracket is provided with a primary side wire bobbin and a secondary side wire bobbin on the bottom surface of the juncture of a primary side winding area and a secondary side winding area; one end of a secondary side wire is welded on a pin on the outer side of the primary side winding area, then steps over a primary side coil of the primary side winding area, and enters an incoming line slot of the secondary side winding area to wind out a secondary side coil after the secondary side wire bobbin is horizontally enwound and fixed; and thus, the secondary side coil can be positioned on the bottom surface of the bobbin bracket through a cross wire section of the primary side coil, not only does not contact the primary side coil, but also is far away from the bottom surface of an iron core inserted in the middle of the bobbin bracket, and when high-frequency current is input, the jump spark between a wire jumper section and the iron core can be avoided without an additional electric insulation cover.
Description
[technical field]
The utility model is about a kind of magnetic element as transformer, particularly about a kind of high-gradient magnetism element and drum stand of saving without the electric insulation cover thereof.
[background technology]
Seeing also Fig. 5 to shown in Figure 7, is a kind of magnetic element structure as high frequency transformer, and it includes:
One drum stand 50, be to be the long flat rectangular shape of a hollow, its two minor face outwards is provided with several metal pins 53a, 53b, for using with the electrical wire board welding, this drum stand 50 includes primary side spiral district 51 and secondary side spiral district 52, wherein this secondary side volume circle district 51 forms several by the winding slot that ring lug 520 separates at interval, and wherein two relative sides of the ring lug 520 in nearly primary side spiral district 51 outwards are extended with a secondary side electric wire spool 521 more respectively;
One or two lateral coils 52, it is the secondary side spiral district 52 that is around in this drum stand 50 by the secondary side coil of wire, wherein an end of these primary side electric wire two ends is the wherein metal pin 53a that are welded in nearly primary side spiral district 51 earlier, after stretching strides across first siding ring 60 again, with vertical winding method winding number therein on secondary side electric wire spool 521, to form a cross-line section 71, be wound in again afterwards in several winding slots in secondary side spiral district 52, the other end be soldered on the wherein metal pin 53b in nearly secondary side spiral district 52;
One electric insulation cover 80, be to comprise a long rectangle underframe 81 and a top cover 82, this top cover 82 is to extend upward from two long relatively inboards of seat frame 81, and is formed with opening in 81 liang short inboards of relative underframe, and these frame 81 bottom surface correspondences are formed with a storage tank 811 apart from cross-line section 71 positions again; When electric insulation cover 80 when the top of drum stand 50 is covered with downwards, this underframe 81 can be fixed on the two short sides of drum stand 50, wherein this cross-line section 71 can be placed in the storage tank 811 of underframe 81, and two relative openings of this top cover 82 are central hole of aiming at and being communicated with drum stand 50;
