Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

Example (b): referring to fig. 1-4, an electronic transformer easy to assemble is described in this embodiment by taking a typical electronic transformer as an example, and includes a magnetic core, a bobbin 1 and a coil 6 wound on the bobbin 1, where the magnetic core includes two magnetic core units 2 oppositely arranged and spliced, the magnetic core unit 2 includes a main core base 201 and two butt-jointing columns 202 arranged perpendicular to the main core base 201, and on one magnetic core unit 2, the butt-jointing columns 202 are cylindrical and have two bilateral symmetry. The winding frame 1 is of a hollow tubular structure, the coil 6 is wound on the winding frame 1, in order to facilitate wiring, the coil 6 is usually connected with a wiring board 5, and the wiring board 5 is fixed at one end of the winding frame 1.

In the conventional assembly method, the two magnetic core single pieces 2 are bundled by using adhesive tapes after being spliced, or the butt-joint column 202 is perforated and connected by using bolts.

In this embodiment, a groove 203 extending along the length direction of the docking post 202 is formed in the side surface of the docking post 202, positioning rods 3 are arranged at two ends of the bobbin 1, and a buckle plate 4 extending towards the center line direction of the bobbin 1 is arranged at the tail end of each positioning rod 3; the positions of the positioning rod 3 and the buckle plate 4 meet the following requirements: after the magnetic core single piece 2 is inserted into the winding framework 1, the positioning rod 3 is accommodated in the groove 203, and the pinch plate 4 abuts against the edge of the magnetic core single piece 2.

The positioning rod 3 extends into a central hole of the bobbin 1, and the positioning rod 3 can be matched with the groove 203 to position the bobbin 1.
