Description

Technical Field

[0001] This utility model relates to the field of transformer accessories technology, specifically a bakelite frame structure for transformers. Background Technology

[0002] Bakelite frames are insulating structural components in transformers used to support and secure the windings. They are typically made of phenolic resin (Bakelite). Bakelite is a thermosetting plastic with excellent insulation and heat resistance, and is widely used in electrical equipment, particularly suitable for transformers with low to medium frequency, high insulation requirements, and cost sensitivity.

[0003] The pins of the bakelite frame are usually fixed inside the frame, while the ends are thin and exposed. Before the transformer is manufactured and after the transformer is manufactured, when it is transported to the distributor through logistics, the exposed pins are easily collided with the production line, containers, logistics boxes and other structures. The pins are usually made of copper material with tin or other materials plated on the surface. The overall strength and conductivity are good, but the strength is low. This can cause the pins to bend and deform. In severe cases, they may break directly. Moreover, bending and deformation can easily lead to fatigue damage and subsequent fracture. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a bakelite frame structure for transformers to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bakelite frame structure for a transformer, comprising a frame body, with support plates fixed to the lower outer surface and the lower back of the frame body, and foot holes opened at the bottom of the support plates; an mounting plate connected to the outer surface of the frame body, with pins penetrating through the bottom of the mounting plate, and first mounting holes opened on the outer surfaces of both the mounting plate and the support plate; hoops connected to both sides of the outer surfaces of the mounting plate and the support plate, with sheaths fixed to the outer surfaces of the hoops, and second mounting holes opened on both sides of the outer surfaces of the hoops and the sheath; and third mounting holes opened above and below the outer surfaces of the hoops and the sheath, with first bolts connected inside the second and third mounting holes.

[0006] By adopting the above technical solution, when transportation is required, workers first separate the mounting plate from the support plate, retracting the tips of the pins into the pin holes. Then, workers perpendicularly distribute the clamping plate to the mounting plate and support plate, and tighten the first bolt through the first and second mounting holes, making the three parts arranged in an I-shape. This prevents the pins from protruding excessively, reducing the occurrence of pin collision deformation and damage. Furthermore, the sheath acts as a buffer, reducing the impact of bumps on the bakelite frame during transportation, as shown in the figure. When it is necessary to install a magnetic core or mount a transformer on a circuit board during production... The workers first remove the first bolt, then remove the clamp plate and the sheath. After that, the workers attach the mounting plate to the support plate so that the pins extend from the bottom of the bakelite frame without obstructing the placement holes, thus facilitating the insertion of the magnetic core. If the transformer is being installed on the circuit board, the workers horizontally reinstall the clamp plate and tighten the first bolt through the first and third mounting holes. The clamp plate prevents the mounting plate from separating from the support plate and strengthens the structure, distributing the stress on the mounting plate and support plate. Combined with the silicone sheath, it buffers external impacts, improves shock resistance, and reduces the risk of brittle cracking.

[0007] Furthermore, the hoop is made of 304 stainless steel, and the sheath is made of high-temperature resistant silicone rubber.

[0008] By adopting the above technical solutions, the 304 stainless steel hoop plate has high strength and corrosion resistance, extending the service life of the structure. The sheath is made of silicone rubber, which is corrosion resistant, has good cushioning properties, and can withstand high temperatures of 150 degrees Celsius to below 200 degrees Celsius for a long time.

[0009] Furthermore, the pin is slidably connected to the through-hole.

[0010] By adopting the above technical solution, when transportation is required, the staff first separates the mounting plate from the support plate, so that the top of the pin is retracted into the pin hole, so that the pin will not protrude excessively and reduce the occurrence of pin collision deformation and damage. When it is necessary to install the magnetic core or install the transformer on the circuit board during the production process, the mounting plate and the support plate are attached to make the pin extend from the bottom of the bakelite frame.

[0011] Furthermore, the hoop is detachably connected to the mounting plate and the support plate by the first bolt, and the longitudinal section of both the hoop and the sheath is "C" shaped.

[0012] By adopting the above technical solution, the longitudinal section of the hoop plate is C-shaped, which makes it easy to clamp the mounting plate and support plate when it is installed horizontally, thereby increasing the structural strength and dispersing the stress on the mounting plate and support plate.

[0013] Furthermore, the back of the hoop and the sheath are provided with multiple grooves.

[0014] By adopting the above technical solution, the multiple grooves of the hoop and the sheath can, firstly, limit the distance between the mounting plate and the support plate when the hoop is assembled vertically, thus preventing the mounting plate from moving up or down, and secondly, prevent the hoop from colliding with the pins when it is assembled horizontally.

[0015] Furthermore, the main frame, mounting plate, and support plate are all made of bakelite material.

[0016] By adopting the above technical solution, the main frame, mounting plate and support plate are made of bakelite, which has the advantages of low cost, good insulation and good heat resistance.

[0017] Furthermore, placement holes are provided on the outer surface of the main skeleton body.

[0018] By adopting the above technical solution, it is easy to put the magnetic core into the skeleton body and set the coil around the skeleton body to form a small transformer.

[0019] Furthermore, the top of the mounting plate is connected to a cover plate and a second bolt, and the pin cross-section is "T" shaped.

[0020] By adopting the above technical solution, the pins are placed inside the mounting plate. Due to the shape of the pins, they will not fall off from the bottom of the mounting plate. Then, the cover plate covers the top of the mounting plate, thereby preventing the pins from falling upwards. The second bolt is tightened to prevent the cover plate from loosening and falling off.

[0021] Furthermore, both the first bolt and the second bolt are nylon bolts.

[0022] By adopting the above technical solution, since both the first and second bolts are nylon bolts, they provide insulation, preventing the first and second bolts from accidentally touching the pins and causing a short circuit due to the conduction current.

[0023] In summary, the present invention has the following main advantages:

[0024] This invention utilizes a configuration of pins, a clamp plate, a sheath, a mounting plate, a support plate, and a first bolt. During transport, the mounting plate and support plate are first separated. The clamp plate is then perpendicularly positioned to the mounting and support plates, and the first bolt is tightened through the first and second mounting holes, forming an I-shape. This prevents the pins from protruding excessively, reducing the risk of pin deformation and damage from impacts. During production, when a magnetic core needs to be installed or a transformer needs to be mounted on a circuit board, the first bolt is removed, followed by the clamp plate and sheath. The mounting plate and support plate are then attached, allowing the pins to extend from the bottom of the bakelite frame without obstructing the mounting holes. If a transformer is being installed, the clamp plate is reinstalled, and the first bolt is tightened through the first and third mounting holes. The clamp plate prevents separation of the mounting and support plates, strengthens the structure, distributes stress on the mounting and support plates, and, combined with the silicone sheath, buffers external impacts, improving shock resistance and reducing the risk of brittle fracture. It also facilitates pin protection. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] Example 1:

[0034] A type of bakelite frame structure for transformers, such as Figures 1-5 As shown, the system includes a main frame 1, with support plates 7 fixed to the lower outer surface and the lower back of the main frame 1. The support plates 7 have foot holes 8 at their bottom. A mounting plate 6 is connected to the outer surface of the main frame 1. The main frame 1, mounting plate 6, and support plate 7 are all made of bakelite. A pin 3 passes through the bottom of the mounting plate 6 and slides with the foot hole 8. First mounting holes 9 are provided on the outer surfaces of both the mounting plate 6 and the support plate 7. Hoop plates 4 are connected to both sides of the outer surfaces of the mounting plate 6 and the support plate 7. The hoop plates 4 are made of 304 stainless steel, and a protective cover is fixed to the outer surface of the hoop plates 4. The sleeve 5 and sheath 5 are made of high-temperature resistant silicone rubber. Both the hoop plate 4 and the sheath 5 have a "C"-shaped longitudinal section. Multiple grooves are provided on the back of both the hoop plate 4 and the sheath 5. Second mounting holes 10 are provided on both sides of the outer surface of both the hoop plate 4 and the sheath 5. Third mounting holes 11 are provided above and below the outer surface of both the hoop plate 4 and the sheath 5. First bolts 12 are connected inside the second mounting holes 10 and the third mounting holes 11. The hoop plate 4 is detachably connected to the mounting plate 6 and the support plate 7 via the first bolts 12. When transportation is required, the workers first separate the mounting plate 6 from the support plate 7. The tip of pin 3 is retracted into the through hole 8. The worker then vertically distributes the clamp plate 4, mounting plate 6, and support plate 7, and tightens the first bolt 12 through the first mounting hole 9 and the second mounting hole 10, making the three parts arranged in an I-shape. This prevents pin 3 from protruding excessively, reducing the occurrence of pin 3 collision deformation and damage. The sheath 5 also acts as a buffer, reducing the impact of bumps on the bakelite frame during transportation. When it is necessary to install a magnetic core or mount a transformer on the circuit board during production, the worker first removes the first bolt 12 before removing the clamp plate 4 and the sheath 5. After removal, the staff will attach the mounting plate 6 and the support plate 7 so that the pins 3 extend from the bottom of the bakelite frame without obstructing the placement hole 2, thus facilitating the insertion of the magnetic core. If the transformer is to be installed on the circuit board, the staff will horizontally reinstall the clamp plate 4 and tighten the first bolt 12 through the first mounting hole 9 and the third mounting hole 11. The clamp plate 4 prevents the mounting plate 6 from separating from the support plate 7, strengthens the structure, disperses the stress on the mounting plate 6 and the support plate 7, and, together with the silicone sheath 5, buffers external impacts, improves shock resistance, and reduces the risk of brittle cracking.

[0035] See Figures 1-3 In the above embodiment, a placement hole 2 is provided on the outer surface of the skeleton body 1 to facilitate the placement of the magnetic core into the skeleton body 1, and to cooperate with the coils set around the skeleton body 1 to form a small transformer.

[0036] Example 2:

[0037] Based on the above embodiment 1, the following settings are made to facilitate fixing pin 3.

[0038] See Figure 1 , Figure 2 , Figure 4 and Figure 5 In the above embodiment, the top of the mounting plate 6 is connected to a cover plate 13 and a second bolt 14. The pin 3 has a "T" shaped cross section. The first bolt 12 and the second bolt 14 are both nylon bolts. When the pin 3 is placed inside the mounting plate 6, the shape of the pin 3 prevents it from falling off the bottom of the mounting plate 6. Then, the cover plate 13 covers the top of the mounting plate 6, thereby preventing the pin 3 from falling upward. The second bolt 14 is tightened to prevent the cover plate 13 from loosening and falling off. Furthermore, since the first bolt 13 and the second bolt 14 are both nylon bolts, they provide insulation, preventing the first bolt 13 and the second bolt 14 from accidentally touching the pin 3 and causing a short circuit.

[0039] The implementation principle of this utility model is as follows: First, when transportation is required, the workers separate the mounting plate 6 from the support plate 7, causing the tip of the pin 3 to retract into the through hole 8. Then, the workers vertically distribute the clamping plate 4 with the mounting plate 6 and the support plate 7, and tighten the first bolt 12 through the first mounting hole 9 and the second mounting hole 10, making the three arranged in an I-shape. This prevents the pin 3 from protruding excessively, reducing the occurrence of collision deformation and damage to the pin 3. Furthermore, the sheath 5 acts as a buffer, reducing the impact of bumps on the bakelite frame during transportation. Figure 2 As shown;

[0040] When it is necessary to insert a magnetic core or mount a transformer onto a circuit board during production, the worker first removes the first bolt 12, then removes the clamp plate 4 and the sheath 5. Afterwards, the worker attaches the mounting plate 6 to the support plate 7 so that the pins 3 protrude from the bottom of the bakelite frame without obstructing the placement hole 2, thus facilitating the insertion of the magnetic core. If the transformer is being mounted onto a circuit board, the worker horizontally reinstalls the clamp plate 4 and tightens the first bolt 12 through the first mounting hole 9 and the third mounting hole 11. The clamp plate 4 prevents the mounting plate 6 from separating from the support plate 7, strengthens the structure, distributes the stress on the mounting plate 6 and support plate 7, and, together with the silicone sheath 5, buffers external impacts, improving shock resistance and reducing the risk of brittle cracking.
