Description

Technical Field

[0001] This utility model relates to the field of power distribution technology, and in particular to an electromagnetic component frame. Background Technology

[0002] Currently, the side plates and bottom plates of existing electromagnetic component frames are spliced ​​together by slotting and interlocking, which makes it difficult to guarantee the installation and positioning accuracy between the bottom plate and the side plates, increases processing costs, and reduces production efficiency. At the same time, the L-shaped frame structure makes it difficult to ensure the accurate installation position of the transformer pins, and the pin positions need to be fixed by fixtures during production, which increases tooling costs and labor costs. Utility Model Content

[0003] The purpose of this utility model is to solve the problems of existing electromagnetic component skeletons where the side plates and bottom plates are spliced ​​by slotting and interlocking, which makes it difficult to guarantee the installation accuracy and positioning accuracy between the bottom plate and the side plates, increases processing costs and reduces production efficiency. At the same time, the L-shaped skeleton structure makes it difficult to ensure the accurate installation position of the transformer pins and the stability after installation is insufficient. The present invention provides an electromagnetic component skeleton.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an electromagnetic component frame for mounting a transformer, the transformer having a magnetic core, windings and several pins, including a base plate and a side plate, the side plate having several first pin holes for the transformer pins to pass through, and the base plate having several second pin holes for the transformer pins to pass through; the base plate and the side plate are arranged perpendicularly to each other and integrally formed, the connection between the side plate and the base plate has a reinforcing structure, and the base plate has a limiting structure for defining the installation position of the transformer. By setting the base plate and side plates perpendicularly to each other and molding them as a single piece, the installation and positioning accuracy can be effectively guaranteed, avoiding the problems that arise from slotted splicing of the base plate and side plates. This also ensures the accuracy and stability of the 90° angle between the base plate and side plates, thus guaranteeing the accuracy of the transformer pins entering the first and second pin holes. Furthermore, the reinforcing structure at the connection between the base plate and side plates effectively improves the strength of the frame and ensures the stability of the 90° angle. Simultaneously, the second pin hole facilitates easy installation of the transformer pins while preventing pins from detaching, thus ensuring the stability of the transformer pins within the second pin hole. In addition, the limiting structure effectively improves the positioning accuracy of the transformer core mounted on the electromagnetic component frame.

[0005] Furthermore, several first pin holes are disposed on the top of the side plate, and each first pin hole has a sleeve protrusion with a stepped surface. The secondary pin of the transformer passes through the first pin hole of the side plate, through the sleeve protrusion, and out of the electromagnetic component frame, and is then electrically connected to the external PCB board by soldering.

[0006] Furthermore, the second pin hole includes a channel portion and a positioning portion that are interconnected, the shape of which is adapted to the shape of the pin. When inserting the secondary-side pin of the transformer into the first pin hole, the primary-side pin of the transformer is first inserted into the second pin hole through the channel portion. Then, the primary-side pin is rotated 90°, causing it to embed into the positioning portion of the second pin hole, thereby completing the operation of installing the primary-side pin of the transformer into the second pin hole of the base plate. In other possible embodiments, the second pin hole can be located on the side plate, and the first pin hole can be located on the base plate. Furthermore, by adapting the shape of the positioning portion to the shape of the transformer pin, the fit between the primary-side pin of the transformer and the positioning portion of the second pin hole can be effectively ensured, ensuring that the primary-side pin is completely embedded within the positioning portion of the second pin hole.

[0007] Furthermore, the opening width of the positioning part is greater than the opening width of the channel part. By setting the opening width of the positioning part to be greater than the opening width of the channel part, it is possible to effectively prevent the transformer pins from coming out of the second pin hole after they are embedded in the positioning part of the second pin hole, thereby effectively ensuring the stability of the transformer pins installed in the second pin hole.

[0008] Furthermore, the reinforcing structure comprises several reinforcing ribs located at the connection points between the base plate and the side plates. These reinforcing ribs effectively improve the strength of the frame and ensure the stability of the 90° angle formed between the base plate and the side plates.

[0009] Furthermore, the top of the side plate is provided with several filling protrusions, which, along with the reinforcing ribs, abut against the transformer and form a heat dissipation channel. The use of filling protrusions effectively prevents deformation of the top of the side plate due to adhesive stress after application, further ensuring the overall structural stability of the electromagnetic component frame. Moreover, the heat dissipation channel formed by the filling protrusions and reinforcing ribs abutting against the transformer effectively improves the transformer's heat dissipation performance.

[0010] Furthermore, the side plate is also provided with several heat dissipation holes. By utilizing these heat dissipation holes on the side plate, the heat dissipation effect of the transformer can be further improved.

[0011] Furthermore, the limiting structure consists of limiting plates disposed at both ends of the base plate. By utilizing the limiting plates, the installation position of the transformer core on the electromagnetic component frame can be effectively limited, thereby effectively improving the installation positioning accuracy and stability of the transformer.

[0012] Furthermore, the side plate has several first positioning posts at both ends, and the bottom plate has several second positioning posts at its bottom. By utilizing the first positioning posts of the side plate and the second positioning posts of the bottom plate, the positioning accuracy between the side plate and the bottom plate of the electromagnetic component firmware and the PCB board can be effectively improved, thereby improving the positioning accuracy of the pins of the transformer mounted on the side plate and the bottom plate for soldering and electrical connection with the PCB board.

[0013] Furthermore, the electromagnetic component frames are integrally formed. By integrally forming multiple electromagnetic component frames, the required number of transformers in different application scenarios can be effectively met, thereby effectively enriching the application scenarios of the electromagnetic component frames.

[0014] The beneficial effects of the electromagnetic component frame provided by this utility model are as follows: By setting the base plate and side plates perpendicular to each other and integrally forming them, the installation accuracy and positioning accuracy that would be difficult to guarantee due to the slotted splicing method of the base plate and side plates can be effectively avoided. It also effectively ensures the accuracy and stability of the 90° angle formed between the base plate and side plates, thereby effectively ensuring the accuracy of the transformer pins entering the first and second pin holes. Furthermore, by utilizing the reinforcing structure at the connection between the base plate and side plates, the strength of the frame can be effectively improved, ensuring the stability of the 90° angle. Simultaneously, by utilizing the second pin hole, the ease of installation of the transformer pins into the second pin hole is ensured, while the cross-sectional design of the second pin hole prevents the pins from coming out, thus effectively ensuring the stability of the transformer pins installed in the second pin hole. In addition, by utilizing the limiting structure, the positioning accuracy of the transformer core installed on the electromagnetic component frame can be effectively improved.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

Figure 2 A side view of the electromagnetic component frame 100. Figure 3 Bottom view of the electromagnetic component frame 100 Figure 4 Schematic diagram of transformer 200 mounted on electromagnetic component frame 100. Figure 5This is a schematic diagram of multiple electromagnetic component frames 100 integrally formed in other embodiments. In the embodiment provided by this utility model, the electromagnetic component frame 100 is used to mount a transformer 200, which has a magnetic core, windings, and a plurality of pins. The electromagnetic component frame 100 includes a base plate 20 and a side plate 10. The side plate 10 has a plurality of first pin holes 11 for the pins of the transformer 200 to pass through, and the base plate 20 has a plurality of second pin holes 21 for the pins of the transformer 200 to pass through. The base plate 20 and the side plate 10 are arranged perpendicularly to each other and integrally formed. The connection between the side plate 10 and the base plate 20 has a reinforcing structure, and the base plate 20 has a limiting structure 40 for defining the mounting position of the transformer 200. By setting the base plate 20 and side plate 10 perpendicularly to each other and molding them as a single piece, the installation and positioning accuracy can be effectively guaranteed, avoiding the problem of difficulty in ensuring the installation accuracy and positioning accuracy caused by the slotted splicing method of the base plate 20 and side plate 10. This also effectively ensures the accuracy and stability of the 90° angle formed between the base plate 20 and side plate 10, thereby effectively ensuring the accuracy of the transformer 200 pins entering the first pin hole 11 and the second pin hole 21. Furthermore, by using the reinforcing structure set at the connection between the base plate 20 and side plate 10, the strength of the frame can be effectively improved, ensuring the stability of the 90° angle. At the same time, by using the second pin hole 21, the installation of the transformer 200 pins into the second pin hole 21 can be effectively guaranteed, while the cross-sectional design of the second pin hole 21 can prevent the pins from coming out of the second pin hole, thereby effectively ensuring the stability of the transformer 200 pins installed into the second pin hole 21. In addition, by using the limiting structure 40, the positioning accuracy of the transformer 200 core installed on the electromagnetic component frame 100 can be effectively improved.

[0019] like Figure 1 and Figure 2 As shown, several first pin holes 11 are provided on the top of the side plate 10, and each first pin hole 11 has a sleeve protrusion 111 with a stepped surface. The secondary side pins of the transformer 200 pass through the first pin holes 11 of the side plate 10, and after passing through the sleeve protrusion 111, they exit the electromagnetic component frame 100 and are then electrically connected to the external PCB board by soldering.

[0020] like Figure 1 and Figure 3As shown, the second pin hole 21 includes a channel portion 211 and a positioning portion 212 that are interconnected. The shape of the positioning portion 212 is adapted to the shape of the pin. When inserting the secondary-side pin of the transformer 200 into the first pin hole 11, the primary-side pin of the transformer 200 is first inserted into the second pin hole 21 through the channel portion 211. Then, the primary-side pin is rotated 90°, causing it to embed into the positioning portion 212 of the second pin hole 21, thus completing the operation of installing the primary-side pin of the transformer 200 into the second pin hole 21 of the base plate 20. In other possible embodiments, the second pin hole 21 can be disposed on the side plate 10, and the first pin hole 11 can be disposed on the base plate 20. Furthermore, by adapting the shape of the positioning portion 212 to the shape of the pin of the transformer 200, the fit between the primary-side pin of the transformer 200 and the positioning portion 212 of the second pin hole 21 can be effectively ensured, ensuring that the primary-side pin is completely embedded in the positioning portion 212 of the second pin hole 21.

[0021] like Figure 1 and Figure 3 As shown, the opening width of the positioning part 212 is greater than the opening width of the channel part 211. By setting the opening width of the positioning part 212 to be greater than the opening width of the channel part 211, the situation where the pins of the transformer 200 come out of the second pin hole 21 after being embedded in the positioning part 212 of the second pin hole 21 can be effectively avoided, thereby effectively ensuring the stability of the pins of the transformer 200 installed in the second pin hole 21. At the same time, the second pin hole 21 provided by this utility model is also provided with adhesive holes on both sides, thereby improving the adhesion of the adhesive after curing on the skeleton.

[0022] like Figure 1 As shown, the reinforcing structure consists of several reinforcing ribs 30 located at the connection between the base plate 20 and the side plate 10. By utilizing the reinforcing ribs 30, the strength of the frame can be effectively improved, ensuring the stability of the 90° angle formed between the base plate 20 and the side plate 10.

[0023] like Figure 1 and Figure 4 As shown, Figure 4 The image provides front and side views of the transformer 200 mounted on the electromagnetic component frame 100. Several filling protrusions 12 are provided on the top of the side plate 10. The filling protrusions 12 and reinforcing ribs 30 abut against the transformer 200 and form a heat dissipation channel. The use of the filling protrusions 12 effectively prevents deformation of the top of the side plate 10 due to adhesive stress after adhesive application, further ensuring the overall structural stability of the electromagnetic component frame 100. Furthermore, the heat dissipation effect of the transformer 200 is effectively improved by utilizing the heat dissipation channel formed by the filling protrusions 12 and reinforcing ribs 30 abutting against the transformer 200. Figure 1As shown, the side plate 10 is also provided with several heat dissipation holes 13. By utilizing the several heat dissipation holes 13 on the side plate 10, the heat dissipation effect of the transformer 200 can be further improved.

[0024] like Figure 1 As shown, the limiting structure 40 is a limiting plate disposed at both ends of the base plate 20. By using the limiting plate, the installation position of the magnetic core of the transformer 200 on the electromagnetic component frame 100 can be effectively limited, thereby effectively improving the installation positioning accuracy and stability of the transformer 200.

[0025] like Figure 1 and Figure 2 As shown, the side plate 10 has several first positioning posts 14 at both ends, and the bottom plate 20 has several second positioning posts 22 at its bottom. By utilizing the first positioning posts 14 of the side plate 10 and the second positioning posts 22 of the bottom plate 20, the positioning accuracy between the side plate 10 and the bottom plate 20 of the electromagnetic component firmware and the PCB board can be effectively improved, thereby improving the positioning accuracy of the pins of the transformer 200 mounted on the side plate 10 and the bottom plate 20 for soldering and electrical connection with the PCB board.

[0026] like Figure 5 As shown, several electromagnetic component frames 100 are integrally formed. By integrally forming multiple electromagnetic component frames 100, the required number of transformers 200 in different application scenarios can be effectively met, thereby effectively enriching the application scenarios of the electromagnetic component frame 100.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
