Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and more specifically to a toroidal transformer. Background Art

[0002] Toroidal transformer is a major type of electronic transformer. Its main use is as a power transformer and isolation transformer. It is widely used in computers, medical equipment, telecommunications, instruments and lighting, etc., and has good market prospects and social benefits.

[0003] Some patent documents related to toroidal transformers are disclosed in the prior art. A Chinese patent with application number CN201922052626.8 discloses a toroidal transformer, including an annular core, a primary winding and a secondary winding. The primary winding and the secondary winding are both wound on the outside of the annular core. A silicone sleeve is provided on the outer jacket of the copper wire of the primary winding and the secondary winding. A transformer casing is provided on the outside of the annular core after the primary winding and the secondary winding are wound. An iron core fixing member is provided in the transformer casing. A casing is provided on the outside of the primary winding, so that the primary winding can be The primary winding has a long service life, and the secondary winding is a high-current winding. The ordinary winding process is difficult to wind with an ordinary winding machine because the enameled wire is too thick and the size of the annular core has specific requirements. The use of silicone sleeves to manually wind multiple strands of bare copper wire can meet the requirements. The multiple strands of bare copper wire are soft and easy to wind manually. This winding method is safe and reliable, and the operation is simple. A smaller high-quality annular core can be used to make a high-power and low-loss transformer. The setting of the core fixing parts makes it easy to position and install the transformer casing 3 and the annular core 1, thereby improving the installation efficiency.

[0004] In the above patent, the toroidal transformer is fixed by bolts. After long-term use, the bolts are prone to rust, making the toroidal transformer difficult to disassemble and replace. For this reason, we propose a toroidal transformer. Utility Model Content
