Abstract
The utility model discloses an improved transformer, which comprises an magnet core and a primary winding and a secondary winding which are sleeved on the magnet core, wherein the magnet core consists of a plurality of stacked silicon steel sheets; a hollow square structure is encircled by two same silicon steel sheet units on each layer of silicon steel sheet; the primary winding and the secondary winding are sleeved on edges of the silicon steel sheet units; and the silicon steel sheet units are right-angled. The silicon steel sheets of the magnet core can completely utilize sheet materials, so that waste materials do not exist and the materials are saved; and each layer of silicon steel sheet consists of the two same silicon steel sheet units, so that the improved transformer simplifies the technology during the process of punch forming, eliminates generation of the wastes materials, reduces the production cost, and is economic and environment-friendly.
Description
Affiliated technical field:
The utility model relates to the electronic product field, especially a kind of modified model transformer.
Background technology:
Iron core in the existing range transformer, common structure is the EI type, and this structure not only causes the waste of material at punching course, cost height, and volume is big, unreasonable structure etc. do not meet the theory of current energy-conserving and environment-protective.
Summary of the invention:
The purpose of this utility model is the defective that overcomes prior art, provides a kind of simple in structure, and dependable performance is saved material, the transformer that production cost is low.
The utility model adopts following technical proposals to realize:
A kind of modified model transformer, include iron core, and be enclosed within primary and secondary winding on the iron core, its described iron core is made of the stacked silicon steel sheet that forms of multi-disc, every layer surrounds empty square structure by two identical silicon steel sheet unit, and described primary and secondary winding is sleeved on the limit of silicon steel sheet unit; Described silicon steel sheet unit is rectangular in shape.
Described silicon steel sheet unit is punched to two " L " shape sheet by complete silicon steel sheet, and two " L " shape sheet cut-off rule is the limit of each lamellar body, i.e. " L " shape sheet of two plate shape unanimities.
The utility model can be complete utilize tablet, no waste material, material-saving, every layer of silicon steel sheet form by two identical silicon steel sheets, simplified technology in the punch forming, stopped waste material generation, reduced production cost, have very big society and economic benefit, meet the theory of energy-conserving and environment-protective.
Description of drawings:
