Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transformer technology, and in particular to a transformer frame. Background Technology
[0002] During transformer assembly, coils are wound around the center of the frame, and then bushings are used to insulate the coils. Leads from both ends of the coils are then routed to pins on the frame. The bushings used in transformers are made of PVC, a transparent, heat-insulating material with a certain thickness.
[0003] In transformers where space is limited, the use of bushings has the following disadvantages:
[0004] 1. Shorten the service life of the transformer. The interior space of a transformer is confined, and the coils generate a large amount of heat during prolonged use. Poor heat dissipation capacity of the bushings can easily lead to overheating and damage to the coils, thus affecting the transformer's performance and lifespan.
[0005] 2. Reduced transformer production efficiency. The installation and removal of bushings for winding coils in transformers is relatively complicated, thus reducing transformer production efficiency.
[0006] 3. Increased economic costs. The use of bushings also increases the unit cost of transformers, reducing economic benefits.
[0007] Therefore, there is an urgent need for a transformer frame that can both support the transformer and provide insulation protection. Summary of the Invention
[0008] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a transformer frame that can improve production efficiency.
[0009] The objective of this utility model can be achieved through the following technical solutions:
[0010] A transformer frame includes winding posts, an upper base, a lower base, and pins.
[0011] A coil is located on the outer side of the winding post. An upper base is connected to the winding post, and an insulating block, a first connecting part, and a protrusion are connected to the upper base. Each insulating block has a first groove on both sides to guide the direction of the coil, and the first grooves are interconnected.
[0012] The first connecting part has a first connecting hole, and each first connecting hole is connected to a pin, and the pin 4 is perpendicular to the first connecting part.
[0013] A lower base is connected to the winding post, and the lower base has multiple second grooves and a second connecting part. The multiple second grooves are not interconnected and are longer than the first grooves. Each of the second connecting parts has a second groove on both sides, and a second connecting hole is formed on the second connecting part. Each second connecting hole also contains a pin. Several isolation strips are connected to the side of the lower base near the winding post.
[0014] Preferably, the distance between the pins should be greater than 5 mm.
[0015] Preferably, a baffle is connected above the upper base, and there is a channel for wiring between the baffle and the first connecting part.
[0016] Preferably, the distance between the coils closest to the upper and lower bases should not exceed 2 mm.
[0017] Preferably, the winding post, upper base, lower base, and stop bar are integrally formed.
[0018] Compared with the prior art, the present invention has the following advantages:
[0019] This invention, by lengthening the lower base and controlling the distance between the coil and the lower base during assembly, achieves complete coil insulation without the need for bushings. The simple design of the lower base serves the same purpose as bushing insulation while simplifying the manufacturing process. It reduces the use of bushings during transformer assembly, making assembly easier for personnel while ensuring safety and accelerating production efficiency. Attached Figure Description

[0036] 1001, Coil. Detailed Implementation
[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0038] like Figure 1 , Figure 2 As shown, a transformer frame includes a winding post 1, an upper base 2, a lower base 3, and pins 4.
[0039] A coil 1001 is located on the outer side of the winding post 1. An upper base 2 is connected to the winding post 1. An insulating block 8, a first connecting part 9, and a protrusion 10 are connected to the upper base 2. Each insulating block 8 has a first groove 6 on both sides to guide the direction of the coil 1001, and the first grooves 6 are interconnected. A first connecting hole 5 is opened on the first connecting part 9, and a pin 4 is connected to each first connecting hole 5, with the pin 4 perpendicular to the first connecting part 9. A lower base 3 is connected below the winding post 1. The lower base 3 has multiple second grooves 11 and a second connecting part 23. The multiple second grooves 11 are not interconnected and are longer than the first grooves 6. Each second connecting part 23 has a second groove 11 on both sides, and a second connecting hole 12 is opened on the second connecting part 23, with a pin 4 connected to each second connecting hole 12. Several isolation strips 7 are connected to the side of the lower base 3 closest to the winding post 1.
[0040] This utility model extends the lower base 3 and uses the second groove 11 to insulate and isolate the coil 1001. This simple design allows the lower base 3 to function as a sleeve and simplifies operations on the production line, cleverly improving production line efficiency while ensuring safety.
[0041] like Figure 1-2 As shown, the distance between the pins 4 should be greater than 5mm.
[0042] like Figure 2 As shown, a baffle 13 is connected above the upper base 2, and there is a channel 14 for wiring between the baffle 13 and the first connecting part 9.
[0043] like Figure 1 As shown, the distance between the coil 1001 closest to the upper base 2 and the lower base 3 should not be greater than 2mm.
[0044] like Figure 1-2 As shown, the winding post 1, the upper base 2, and the lower base 3 are integrally formed.
[0045] The transformer described in this invention typically has multiple coils wound around the outer side of the winding post 1, with each layer of coils isolated by insulating paper. By lengthening the lower base 3 and designing a separate second groove 11 on the lower base 3, we can effectively protect the coils, prevent circuit connections from interfering with each other's electric fields, and ensure the transformer's heat dissipation and safe operation. Through mold making, the integrated molding of the frame can accelerate production efficiency.
[0046] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0047] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the meaning of "and / or" throughout the text includes three solutions. Taking "a transformer frame and / or B" as an example, it includes one transformer frame solution, or solution B, or a solution that simultaneously satisfies both the transformer frame and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
[0048] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0049] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0050] Although this document uses terms such as winding post, upper base, and lower base frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
