Description

Technical Field

[0001] This utility model relates to the field of transformer frame application technology, specifically to a transformer frame with optimized multi-pin layout. Background Technology

[0002] Transformer bobbins are typically made of insulating material and have specific shapes and dimensions. They support the transformer windings and provide insulation protection. Pins are crucial for the transformer to achieve electrical connections with external circuits. Through pins, the transformer can transmit voltage and current generated by the internal windings to the external circuit or receive electrical energy from the external circuit. The method of fixing the transformer usually takes into account the position and layout of the pins. A reasonable fixing method can provide support and positioning for the pins, ensuring that they are not deformed or damaged by external forces during installation and use. However, current technology typically uses bolts to fix the transformer body to the pins. During the fixing process, workers need to tighten multiple bolts, which is cumbersome and time-consuming, increasing workload and reducing efficiency. Therefore, we propose a multi-pin optimized layout transformer bobbin. Utility Model Content

[0003] The purpose of this invention is to provide a multi-pin optimized layout transformer frame to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides a multi-pin optimized layout transformer frame, including a frame with two connecting plates fixedly disposed on its lower side. Frame pins are disposed on the lower side of the two connecting plates. Multiple first sliding grooves are formed on the side of the two connecting plates that are far apart from each other. The frame pins are slidably disposed within the first sliding grooves. A second sliding groove is formed on the upper side of the first sliding groove. A connecting block is slidably disposed within the second sliding groove. The lower side of the connecting block is fixedly connected to one end of the frame pin. Grooves are formed on both sides of the connecting block. Protrusions are slidably disposed within the grooves, and the protrusions penetrate one side of the connecting block. Protrusion grooves adapted to the protrusions are formed on both sides of the second sliding groove. A push-out spring located inside the groove is fixedly connected to one side of the protrusion.

[0005] As a further improvement to this technical solution, a third slide groove is provided on both sides of the second slide groove, and an ejector block is slidably arranged inside the third slide groove.

[0006] As a further improvement to this technical solution, a plurality of support springs are fixedly installed inside the third slide groove. One end of each support spring is fixed to one side of the ejector block, and the support spring is used to apply a thrust to the ejector block toward one side of the second slide groove.

[0007] As a further improvement to this technical solution, limit grooves are provided on both sides of the third slide groove, and limit blocks are slidably arranged inside the limit grooves. Multiple limit blocks are respectively fixedly installed on both sides of the ejector block.

[0008] As a further improvement to this technical solution, the surface of the ejector block near the second slide groove is inclined, the surface of the ejector block away from the connecting block is flush with the third slide groove, and the surface of the ejector block near the connecting block protrudes from the third slide groove.

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

[0010] In this multi-pin optimized layout transformer frame, the connecting block, which is fixedly set at the end of the frame pin, is inserted into the second slide groove. The ejector spring pushes out the protrusion and locks it in the protrusion groove, thereby fixing the relative position between the connecting block and the connecting plate. At the same time, the elastic thrust applied to the ejector block by the support spring pushes out the ejector block and locks the connecting block, increasing the fixing effect of the device on the connecting block. The operation is simple, reduces the workload of the staff, and improves work efficiency. Attached Figure Description

Example 1

[0020] Please see Figures 1-4 As shown, this embodiment provides a multi-pin optimized layout transformer bobbin, including a bobbin 1. Two connecting plates 2 are fixedly disposed on the lower side of the bobbin 1. Bobbin pins 4 are disposed on the lower side of the two connecting plates 2. Multiple first sliding grooves 3 are formed on the side of the two connecting plates 2 that are far apart from each other. The bobbin pins 4 are slidably disposed inside the first sliding grooves 3. By sliding the bobbin pins 4 from the first sliding grooves 3 into the connecting plates 2, it is convenient to install the bobbin pins 4. A second sliding groove 5 is formed on the upper side of the first sliding groove 3. A connecting block 6 is slidably disposed inside the second sliding groove 5. The lower side of the connecting block 6 is fixedly connected to one end of the bobbin pin 4. The position of the skeleton pin 4 is limited by the sliding of the connecting block 6 in the second slide groove 5 to prevent the skeleton pin 4 from falling off. The connecting block 6 has grooves on both sides, and a protrusion 7 is slidably arranged inside the groove. The protrusion 7 passes through one side of the connecting block 6. The second slide groove 5 has protrusion grooves on both sides that are adapted to the protrusion 7. A push-out spring 8 located inside the groove is fixedly connected to one side of the protrusion 7. When the connecting block 6 moves to a certain position, the push-out spring 8 pushes the protrusion 7 out, so that the protrusion 7 is stuck in the protrusion groove, thereby fixing the relative position of the skeleton pin 4 and the connecting plate 2.

[0021] The second slide groove 5 has a third slide groove 9 on both sides. A push-out block 10 is slidably arranged inside the third slide groove 9. Multiple support springs 11 are fixedly arranged inside the third slide groove 9. One end of the support spring 11 is fixed to one side of the push-out block 10. The support spring 11 is used to apply a pushing force to the push-out block 10 towards the side of the second slide groove 5. When the connecting block 6 moves to the point where the protrusion 7 is inserted into the protrusion groove, the push force applied to the push-out block 10 by the push-out support spring 11 pushes out the push-out block 10 and locks the position of the connecting block 6, thereby increasing the fixing effect of the device on the skeleton pin 4. The surface of the push-out block 10 near the second slide groove 5 is inclined, and the surface of the push-out block 10 away from the connecting block 6 is flush with the third slide groove 9. This prevents the push-out block 10 from blocking the connecting block 6 when it is inserted, thus preventing the connecting block 6 from being inserted. At the same time, the surface of the push-out block 10 near the connecting block 6 protrudes from the third slide groove 9, thereby locking the connecting block 6 and fixing the relative position between the connecting block 6 and the connecting plate 2.

[0022] Limiting grooves 12 are provided on both sides of the third slide groove 9. Limiting blocks 13 are slidably arranged inside the limiting grooves 12. Multiple limiting blocks 13 are fixedly installed on both sides of the ejector block 10. The position of the ejector block 10 is limited by the sliding of the limiting blocks 13 in the limiting grooves 12, so as to prevent the support spring 11 from popping the ejector block 10 out and causing device failure.

[0023] In practical use, the user inserts the connecting block 6 fixed on the frame pin 4 into the second slide groove 5. The push force applied to the protrusion 7 by the ejector spring 8 is used to lock the protrusion 7 into the protrusion groove, fixing the relative position between the frame pin 4 and the connecting plate 2. At the same time, the elastic push force applied to the ejector block 10 by the support spring 11 pushes the ejector block 10 out. The inclined surface of the ejector block 10 is used to lock the connecting block 6, increasing the fixing effect of the connecting block 6. The position of the ejector block 10 is limited by the sliding of the limiting block 13 in the limiting groove 12, preventing the ejector block 10 from sliding out of the third slide groove 9.
