Abstract

The invention provides a strong stable type annular transformer. The strong stable type annular transformer comprises an annular iron core, a primary winding, an annular heat dissipation cavity frame,a secondary winding, two annular heat dissipation pads, two pressing plates and a connecting piece. The primary winding is wound on the annular iron core. The annular heat dissipation cavity frame isprovided with a plurality of first supporting rods, a plurality of second supporting rods, a plurality of third supporting rods and a plurality of fourth supporting rods which penetrate through the primary winding and abut against the annular iron core. The secondary winding is wound on the annular heat dissipation cavity frame. The annular heat dissipation pads are provided with a plurality of heat dissipation channels, the two annular heat dissipation pads abut against the secondary winding respectively, and the two pressing plates abut against the two annular heat dissipation pads respectively. The connecting piece comprises a first connecting rod and a second connecting rod. A bearing hole is formed in the bearing groove of the pressing plate, the first connecting rod is inserted intoone bearing hole, and the second connecting rod is inserted into the other bearing hole. The second connecting rod is provided with a screw joint groove, and the first connecting rod is inserted intothe screw joint groove and is in screw joint with the second connecting rod. According to the transformer, the heat dissipation performance is enhanced, and the structural stability is improved.

Description

technical field [0001] The invention relates to the technical field of toroidal transformers, in particular to a highly stable toroidal transformer. Background technique [0002] Toroidal transformer is a large type of electronic transformer, which has been widely used in household appliances and other electronic equipment with high technical requirements. Its main use is as a power transformer and isolation transformer. Toroidal transformers have a complete series abroad, which are widely used in computers, medical equipment, telecommunications, instruments and lighting. my country's toroidal transformer has grown from scratch in the past ten years, and has formed a considerable production scale so far. In addition to meeting domestic demand, it has also been exported in large quantities. Domestically, it is mainly used in audio equipment and automatic control equipment of home appliances, as well as quartz lamp lighting. [0003] However, in a toroidal transformer, a pri...
