Transformer structure

Abstract

The invention relates to a transformer structure. The transformer structure comprises a first magnetic conductive element, a coil winding and a second magnetic conductive element, wherein the first magnetic conductive element has a winding part and a flange part; the flange part is arranged on the side edge of the winding part; the flange part has a first main body and an extension structure; the extension structure extends out of the first main body; the coil winding is arranged on the winding part; and the second magnetic conductive element is arranged corresponding to the first magnetic conductive element, and the second magnetic conductive element has a jointing structure. The first magnetic conductive element and the second magnetic conductive element are jointed with the jointing structure through the extension structure, so that magnetic flux, which is generated after the winding part is wound by the coil winding, is transmitted to the jointing structure through the first main body and the extension structure.

Description

technical field [0001] The invention relates to a transformer structure, in particular to a transformer structure suitable for the communication field. Background technique [0002] Existing pulse transformers for communication, such as broadband transmission transformers, are usually used in electronic equipment in the communication field such as the Internet or local area network, for the purpose of transmitting digital signals. [0003] see figure 1 , which is a structural schematic diagram of a known pulse transformer. As shown in the figure, the known pulse transformer 1 is composed of a drum-shaped iron core 11, a plate-shaped iron core 12 and a coil winding 13, wherein the drum-shaped iron core 11 includes a winding part 111 and The flange part 112, the flange part 112 is arranged on both sides of the winding part 111, the coil winding 13 surrounds the winding part 111, the plate-shaped iron core 12 is arranged on the top of the drum-shaped iron core 11, and its part...

AI Technical Summary

Problems solved by technology

[0008] The main purpose of the present invention is to provide a transformer structure to solve the problem that the joint surface between the flange part and the plate iron core of the known pulse transformer is a horizontal plane, and there will be magnetic flux leakage at the terminals on both sides of the plate iron core, so that The utilization rate of the magnetic permeability of the magnetic material is reduced, which limits the inductance of the pulse transformer, etc.
