Description

Technical Field

[0001] The utility model belongs to the technical field of power transformers, in particular to a transformer mounting frame and a switching power transformer. Background Art

[0002] A switching power supply transformer is a power transformer with a switching tube added. In addition to the voltage conversion function of an ordinary transformer in the circuit, it also has insulation isolation and power transmission functions. It is generally used in switching power supplies and other occasions involving high-frequency circuits. The switching power supply transformer and the switching tube together constitute a self-excited (or externally excited) intermittent oscillator, thereby modulating the input DC voltage into a high-frequency pulse voltage.

[0003] However, most of the existing switching power supply transformers are composed of a winding and two core frames. After the core frames are connected to the winding, they are directly tied and fixed by tape. After fixation, the stability is poor. At the same time, during the transportation of multiple transformers, they are prone to friction and damage. Therefore, a transformer mounting frame and a switching power supply transformer are proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a transformer mounting frame and a switching power supply transformer, which can utilize the cooperation of a slide groove and a slider as well as the cooperation of a plug-in frame and a plug-in rod to increase the stability of the connection between the winding and the core frame, avoid movement between the winding and the core frame, and at the same time, by being arranged on a semi-cylindrical plug-in block through a fixed sleeve, thereby increasing the stability of the connection between the products, and at the same time, can also reinforce the space between the two core frames, improve the safety of transportation, reduce wear, and solve the existing technical problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
