The origin of this patent invention auto induction coil

An auto induction coil includes initial segment of sheet metal, sheet metal, the number of hops and the end section of metal sheets are sequentially connected, and each relay section of metal sheet is also connected with theconnecting part, the adjacent repeater section of metal sheets folded form the folded part, and sequentially folded around, and with the lap winding methodthe number hops sheet metal layers of warehouse into a coil structure of boxtype multi layered, and the folding portions adjacent layer relay section of metal sheet is not in the same straight axis position, but each other a viewpointand staggered. The folding part to the folding deformation even constitute itssurface insulation process is damaged, due to the folding part is staggeredarranged, and can avoid the short circuit, and always maintain the use function of the auto induction coil is good.

Auto induction coil, is made of flat metal surface insulation process, the autoinduction coil at least includes: initial period of metal sheet; a plurality ofrepeater section of metal sheets, connected to the initial segment of sheet metal, and each relay section of metal sheet is also connected with theconnecting part, the adjacent repeater section of metal sheets folding folding part is formed, and sequentially folded around, and with the lap windingmethod the number of hops sheet metal layers of warehouse into a coilstructure of box type multi layered, and the folding portions adjacent layer relay section of metal sheet is not in the same straight axis position, which is apoint of view each other and the phase staggered; and one end section of metal sheet, connected to the number of hops of sheet metal.
