Description

Technical Field

[0001] This utility model relates to a modular transformer frame, belonging to the technical field of transformer frame technology. Background Technology

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change the magnitude of voltage and current, thereby transmitting electrical energy. Transformers play an extremely important role in power systems and various electronic devices, and the transformer frame is a crucial component of the transformer. It is mainly used to support and fix the transformer coils, while also serving as insulation and heat dissipation.

[0003] Existing transformer frames can only accommodate one coil. When some equipment requires transformers with multi-coil structures, the existing frames cannot meet the requirements and new molds need to be made. Multiple molds need to be designed to accommodate frames with a variety of coil numbers, thus limiting their applicability. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing transformer frames can only accommodate one coil, resulting in poor applicability and an inability to meet the needs of transformers with multi-coil structures.

[0005] To address the aforementioned problems, this utility model provides a modular transformer frame, comprising a top seat, a base, and a winding post. The top seat and the base are fixedly connected by connecting plates on both sides. The winding post is fixedly connected between the two connecting plates. The base has snap-fit ​​mechanisms on both sides. The top seat has slidably connected limiting mechanisms corresponding to the snap-fit ​​mechanisms on both sides. The top seat has through-holes in snap-fit ​​grooves on both sides. The snap-fit ​​mechanisms are inserted into the snap-fit ​​grooves via snap-fit ​​posts. The lower end of the snap-fit ​​posts has a limiting groove, and the limiting mechanisms are inserted into the limiting grooves.

[0006] Furthermore, the snap-fit ​​mechanism also includes a snap-fit ​​plate, with two snap-fit ​​posts fixedly connected to the lower end of the snap-fit ​​plate. One side of the snap-fit ​​plate is provided with a spring sleeved on the outside of the snap-fit ​​posts and fixedly connected to the base. The snap-fit ​​posts are slidably connected to the corresponding slots on the base.

[0007] Furthermore: the limiting mechanism includes a pull handle and a limiting rod, the pull handle is fixedly connected to one end of the limiting rod, and the limiting rod is slidably connected to a slot on the top seat that corresponds to it.

[0008] Furthermore: the limiting rod is fitted with a connecting ring, which is fixedly connected to one end of the limiting rod, and the connecting ring is fixedly connected to the side of the top seat by a spring.

[0009] Furthermore, the limiting groove and the limiting rod have the same diameter.

[0010] The advantages of this utility model compared with the prior art are as follows:

[0011] This patent allows for convenient assembly and fixing of the upper and lower ends of two transformer frames by means of a limiting mechanism on the top seat and a snap-fit ​​mechanism on the base. This facilitates the assembly of multiple frames according to actual usage, avoiding the hassle of re-molding and providing good applicability to transformers with different numbers of coils.
