Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model execution mode is done to describe in detail further below.

As shown in Figure 1; Also can be referring to Fig. 2 and Fig. 3; A kind of transformer that the utility model embodiment provides comprises the iron core-closed 10 of ring-type, on iron core-closed 10 the wall 11 of said ring-type around cyclic skeleton 20; Said cyclic skeleton 20 is for insulation framework and quantity are at least four, and the outer surface of each said cyclic skeleton 20 is all twining line and forming coil.

Referring to Fig. 1, compare prior art, the utility model embodiment through annular iron core-closed 10 on the cyclic skeleton 20 of insulation is set; And twine the structure with support coils through cyclic skeleton 20, can utilize existing traditional coil winding machine coiling to make transformer, owing to it is easy to coiling; So reduced difficulty of processing; Improve production efficiency, need not the spooling equipment of specialty, reduced product cost; The said transformer of the utility model is provided with at least four cyclic skeletons 20; Four cyclic skeletons 20 can be assigned as the skeleton of primary coil 12 (referring to Fig. 2) and the skeleton of secondary coil 13 (referring to Fig. 2) as required; Be that primary coil 12 (referring to Fig. 2) and secondary coil 13 (referring to Fig. 2) all adopt the discrete coiling; Because the cyclic skeleton 20 that uses itself has the good insulation performance performance, so a large amount of insulating material that on iron core-closed 10, need not to reel make iron core-closed 10 good performance of heat dissipation is arranged; Effectively guarantee the performance of said transformer, practiced thrift a large amount of insulating material simultaneously.Therefore because the said transformer of the utility model fundamentally solves coiling difficulty and this two hang-up of weak heat-dissipating that traditional transformer exists, so the said transformer of the utility model is easy to promote.
