Technical Field
The utility model relates to the technical field of transformers, in particular to a mold core device for winding two coils connected in series.
Background
The transformer is an electromagnetic element and mainly comprises a coil, a magnetic core, a framework, an insulating material and the like. In the production process of the existing transformer, an automatic winding machine and a mold core are needed to be used for winding a lead on a framework to form a coil, then the magnetic core is assembled, and the coil is wrapped and fixed by an adhesive tape to form a finished transformer product. However, there are some transformers with main transformer and inductor connected in series, which are formed by connecting the coils of two separate transformers in series, i.e. the two coils need to be connected end to end. In the existing processing technology, two coils are respectively wound and then are soldered by electric iron and tin, and the two coils are soldered end to end. The process has low production efficiency, and the soldering joint needs to be wrapped with adhesive tape for insulation, so the process is complex.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1-3, a mold core device for winding two coils in series is used for winding two coils, I and II (not shown). The device comprises a mold core I1, a mold core II2, a connector 3, a stopper I4 and a stopper II5, wherein the mold core I1 is used for winding a coil I, and the mold core I1 is detachably connected with the connector 3, namely, the mold core I1 and the connector are fastened together through an exposed screw.
The connector 3 is provided with an inclined plane with a certain length, the mold core II2 is provided with an inclined plane with the same length, and after the two inclined planes are combined together, the mold core II2 and the connector 3 are matched to form a cylinder with the same length as the inclined plane for winding the coil II.
The block I4 and the block II5 are positioned at the two ends of the cylinder, are respectively fixed on the connector 3 and the mold core II2 and are fixed through female screws. The stop block I4 is provided with two bending line grooves I41, and the stop block II5 is provided with a bending line groove II51 and a copper strip placing groove 52. The material of mold core II2 and connector 3 is stainless steel.
When two coils are wound, firstly, the coil I is wound on a mold core I1, after the winding is finished, the wire end passes through one of the winding grooves on the stop block I4, then, the coil II is wound, and the winding is carried out on a cylinder formed by inclined planes. When the coil II is wound, one or two copper strips are added in the process of winding the coil II according to the process requirement. And after the winding of the coil II is finished, the wire ends are placed in the winding wire grooves II51, and at the moment, the winding of the two coils is finished. Then the connector 3 and the mold core I1 are loosened, the connector 3 and the exposed screw on the mold core II2 are loosened, the mold core I1 is pulled out from the coil I, then the connector 3 is pulled out, and then the mold core II2 is pulled out, because the connector 3 and the mold core II2 form a bevel sliding relationship and are made of stainless steel, the connector 3 and the mold core II2 are easily separated. Thus, two coils connected in series are wound. Block I4 need not be removed from connector 3 at ordinary times, and block II5 need not be removed from core II2 at ordinary times.
The device is convenient to install, the coil winding process is simple, and the disassembly of the parts is also convenient after the coil winding is finished.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited thereto, and various changes which can be made within the knowledge of those skilled in the art without departing from the gist of the present invention are within the scope of the claims of the present invention.
