Embodiment

For further understanding technology, means and effect that the utility model is taked for reaching predetermined object, refer to following about detailed description of the present utility model and accompanying drawing, believe the purpose of this utility model, feature and feature, go deep into and concrete understanding when one can be obtained thus, but institute's accompanying drawings only provides with reference to and use is described, be not used for the utility model in addition limitr.

The utility model designs a transformer reel, mainly solve two groups of coil overlap wrappings on same wrapping post time, the lead-out wire of inner coil can with the shortcoming of outer coil interlacing contact, therefore the embodiment of the utility model transformer reel please refer to shown in Fig. 4 ~ Fig. 6, Fig. 4 is the embodiment schematic perspective view of the utility model transformer reel, Fig. 5 is the embodiment schematic perspective view after Fig. 4 drum stand winding around, and Fig. 6 is the side elevational cross-section schematic diagram of Fig. 5.

In embodiment of the present utility model, transformer reel 20 includes a coiling barrel mast 21, biside plate 22 and multiple electric pin 23, this biside plate is configured at the both side ends of coiling barrel mast 21 respectively, the outer surface of the coiling barrel mast 21 between biside plate 22 can supply overlap wrapping at least two group coil 30, as shown in Figures 5 and 6, first siding ring is coated on the outside of second siding ring, the center of coiling barrel mast 21 is provided with pass through aperture 24 and runs through between biside plate 22, can stretch in through hole 24 at least one (not shown) unshakable in one's determination, form a transformer.Wherein those electric pins 23 are configured at the outer surface of one of them side plate 22, in the present embodiment, those electric pins 23 can comprise primary side electric pin and secondary side electric pin, and be two opposite end being configured at same side plate 22, the exit of those coils 30 is then wound on those electric pins 23 respectively.In other embodiments, those primary side electric pins and secondary side electric pin are the outer surface or the side board edge that are separately positioned on biside plate.

Feature of the present utility model is the inner surface at side plate 22, namely in the face of the surface of coiling barrel mast 21, be provided with a protrusion 25 and at least one depression conduit 26, in the present embodiment, this protrusion 25 at least contains the inner surface of this side plate 22 most, this depression conduit 26 is extended to the edge of side plate 22 by the outer surface of coiling barrel mast 21, this protrusion 25 can vacate a space near side plate 22 place by limiting coil 30 with depression conduit 26, and the lead-out wire 30 ' of inner coil 30 can be made to be connected on this electric pin 23 via the extraction of this depression conduit 26, and can not arrive with outer coil 30 interlacing contact.In embodiment of the present utility model, the high low head between this protrusion 25 and this depression conduit 26 is at least the height 0.4mm of a coil.

Due in embodiment of the present utility model, those primary sides and secondary side electric pin 23 are only on the outer surface of same side plate 22, therefore only protrusion 25 and depression conduit 26 need be set having side plate 22 inner surface of electric pin 23, and in other embodiments, electric pin is when point being located at biside plate, protrusion 25 and depression conduit 26 can be set on the side plate interior sides surface of secondary side electric pin, or biside plate is all provided with protrusion 25 and depression conduit 26.
