Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, and in particular to a novel bakelite base plate for transformers. Background Technology

[0002] Currently, most frameless energy transformers typically use epoxy board as the base plate, which is bonded to a support plate before windings, magnetic cores, and other components are installed to secure the pins. During manufacturing, the epoxy board needs to be bonded to the support plate. However, due to the smooth surface of epoxy board, it is prone to detachment after bonding, resulting in poor stability and low processing efficiency. Furthermore, epoxy board is not heat-resistant and is prone to deformation and aging. Therefore, there is an urgent need for a new type of bakelite base plate to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a novel bakelite base plate for transformers, in order to solve the technical problems of unstable structure, low production efficiency, and high cost of existing epoxy board base plates.

[0004] This utility model discloses a novel bakelite base plate for transformers, comprising a base plate and a support plate integrally formed therewith. The base plate has a frame structure, and the support plate is disposed on the left and right sides of the surface of the base plate. The outer ends of the support plate are provided with outer reinforcing plates, and the inner side of the support plate is recessed downward to form a mounting surface. The inner side of the mounting surface is provided with an inner reinforcing plate. Both the outer and inner reinforcing plates are triangular structures.

[0005] Preferably, the outer side of the support plate is provided with a plurality of square notches at equal intervals.

[0006] Preferably, the two corresponding inner reinforcing plates and the bottom surface of the base plate form a trapezoidal heat dissipation hole structure.

[0007] Preferably, the bottom of the base plate has outward protrusions at the four corners.

[0008] Preferably, the base plate and the support plate are made of bakelite thermosetting material.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This new type of bakelite base plate for transformers features a robust base plate structure achieved through integrated molding of the base plate and support plate. Reinforcing plates at the front and rear ends of the support plate further enhance its stability. A recessed mounting surface on the inner side of the support plate prevents lateral shifting when the magnetic core is assembled onto the base, further ensuring transformer installation stability. Inner reinforcing plates positioned at the front and rear ends of the mounting surface ensure stability within the support plate. Furthermore, two corresponding inner reinforcing plates and the base plate form a trapezoidal heat dissipation hole structure. When the magnetic core, windings, and other structures are mounted on the base, a certain distance exists between their mounting surfaces and the base plate, allowing heat to dissipate through the holes, thus improving transformer heat dissipation. Four protrusions at the four corners of the base plate facilitate solder penetration during wave soldering. Multiple notches on the outer side of the support plate increase the adhesive bonding area and enhance bonding strength. Attached Figure Description

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] like Figure 1-3As shown, this utility model discloses a novel bakelite base plate for transformers, comprising a base plate 1 and an integrally formed support plate 2. The base plate 1 has a frame structure, and the support plate 2 is located on the left and right sides of the base plate 1. Outer reinforcing plates 21 are provided at both ends of the outer sides of the support plate 2. The inner side of the support plate 2 is recessed downwards to form a mounting surface 22, and an inner reinforcing plate 23 is provided on the inner side of the mounting surface 22. Both the outer reinforcing plates 21 and the inner reinforcing plates 23 are triangular structures. Multiple square notches 24 are equidistantly provided on the outer side of the support plate 2. Two corresponding inner reinforcing plates 23 form a trapezoidal heat dissipation hole structure with the bottom surface of the base plate 1. Outwardly protruding bosses 11 are provided at the four corners of the bottom of the base plate 1. The base plate 1 and the support plate 2 are made of bakelite thermosetting material, ensuring that the base can withstand temperatures above 180 degrees Celsius; the integrally formed structure is more robust, eliminating the need for glue bonding between parts; and the injection mold production process is efficient and cost-effective.

[0018] This utility model discloses a bakelite base plate for a transformer, primarily serving to fix the leads of the internal windings and support the transformer body. It mainly includes a base plate 1 and a support plate 2, both made of bakelite thermosetting material, possessing excellent insulation, heat resistance, and chemical corrosion resistance. By integrally molding the base plate 1 and support plate 2, no adhesive is required during use, ensuring a more robust base plate structure. The support plate 2 is positioned on the left and right sides of the base plate 1 surface to define the installation position of the magnetic core. Reinforcing plates 21 are provided at the front and rear ends of the outer side of the support plate 2, further ensuring the stability of the support plate 2 structure on the base plate 1. A downwardly recessed mounting surface 22 is provided on the inner side of the support plate 2 to prevent lateral displacement when the magnetic core is assembled onto the base, further ensuring the stability of the transformer installation. Qualitatively, by setting an inner reinforcing plate 23 on the inner side of the mounting surface 22, and by setting the inner reinforcing plate 23 at the front and rear ends, the stability of the inner side of the support plate 2 is ensured. In addition, the two corresponding inner reinforcing plates 23 and the base plate 1 form a trapezoidal heat dissipation hole structure. When the magnetic core, winding and other structures are installed on the base, there will be a certain distance between its mounting bottom surface and the base plate 1, and heat will be dissipated from the heat dissipation holes, ensuring better heat dissipation of the transformer. By setting four protrusions 11 on the four corners of the base plate 1, it is convenient for the terminal to be soldered through during wave soldering. By setting multiple notches 24 on the outer side of the support plate 1, the bonding area of ​​the adhesive can be increased and the bonding strength can be improved.

[0019] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
