Description

Technical Field

[0001] This utility model relates to the field of high-voltage transformers, and in particular to a multi-output high-voltage transformer. Background Technology

[0002] In modern automotive electronic systems, the number of electrical devices and functional modules is constantly increasing, leading to more diverse and complex power supply demands. As a core component for power conversion, the on-board transformer supplies power to electrical devices through its internal windings; its performance and function directly affect the stability and reliability of the entire automotive electrical system.

[0003] Traditional automotive transformer frames typically only have a single-output function, making it difficult to simultaneously power multiple electrical devices within a vehicle with varying voltage and power requirements. For example, a car's entertainment system, dashboard, and sensors all require different operating voltages and power. Using a single-output transformer necessitates the additional configuration of multiple voltage conversion devices, which not only increases the system's size and cost but also reduces overall system efficiency and increases the probability of malfunctions.

[0004] Therefore, there is an urgent need for a transformer that can output multiple circuits, thereby reducing the space required for multiple winding circuits by integrating multiple circuits within the transformer. Utility Model Content

[0005] To improve the integration and space utilization of vehicle-mounted transformers, this utility model provides a multi-output high-voltage transformer.

[0006] This utility model provides a technical solution that adopts the following approach:

[0007] A multi-output high-voltage transformer includes a frame and multiple sets of windings disposed within the transformer body. Each winding includes an output pin, an input pin, and a connecting wire. The connecting wire connects the output pin and the input pin. The frame has a mounting portion and a connecting portion. The mounting portion is used to set the input pin and the output pin. The connecting portion is used to connect multiple mounting portions. An isolation portion is provided between the multiple sets of windings. The isolation portion is disposed on the frame. The distance from the top wall of the isolation portion to the bottom wall of the frame is greater than the distance from the top wall of the input pin and the output pin to the bottom wall of the frame.

[0008] Multiple windings are integrated onto the transformer frame and then separated by an isolation section. This increases the creepage distance between adjacent windings, allowing each winding to withstand higher voltages. Simultaneously, it reduces the risk of high-voltage winding penetration and leakage, lowers the probability of short circuits, and helps maintain the output stability of multi-output high-voltage transformers. Furthermore, it reduces electromagnetic interference between the multiple windings, making the input pin voltage less susceptible to interference and resulting in more stable equipment operation.

[0009] Preferably, the multiple input pins extend in the same direction, the multiple output pins extend in the same direction, and the input pins and output pins extend in opposite directions.

[0010] The pins on the frame are arranged parallel to each other, so that the distance between each pin and the same position between adjacent pins is the same. This helps to reduce electromagnetic interference between them, optimize the distribution of electric field, and reduce the frequency of magnetic field crossing.

[0011] Preferably, the isolation section is plate-shaped, and the distance from the isolation section to the input PIN pins on both sides is the same.

[0012] The isolation section is plate-shaped with uniform thickness throughout, ensuring consistent creepage distances between the windings on both sides, which helps maintain the stability of the electric field.

[0013] Preferably, the isolation part is integrally connected to the skeleton.

[0014] By molding the isolation unit and the frame into a single integrated structure through injection molding, the need for additional installation structures for the isolation unit can be reduced, making the installation of the isolation unit simpler. At the same time, it avoids the connection gap between the isolation unit and the frame installation structure, resulting in better isolation performance.

[0015] Preferably, the size of the isolation section is adaptively adjusted according to the creepage distance requirements.

[0016] When the voltage on the winding is higher, a larger injection-molded isolation section can be selected for isolation to ensure stable isolation.

[0017] Preferably, the thickness of the insulating part is 1.3-2 mm.

[0018] Preferably, the thickness of the isolation portion is 1.5 mm or 1.6 mm.

[0019] In summary, this utility model has the following beneficial technical effects:

[0020] Multiple windings are integrated onto the transformer frame and then separated by an isolation section. This increases the creepage distance between adjacent windings, allowing each winding to withstand higher voltages. Simultaneously, it reduces the risk of high-voltage winding penetration and leakage, lowers the probability of short circuits, and helps maintain the output stability of multi-output high-voltage transformers. Furthermore, it reduces electromagnetic interference between the multiple windings, making the input pin voltage less susceptible to interference and resulting in more stable equipment operation.

[0024] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0025] This utility model discloses a multi-output high-voltage transformer.

[0026] Reference Figure 1 as well as Figure 2 A multi-output high-voltage transformer includes a frame 7 and multiple windings disposed within the transformer body. Each winding includes an output pin 1, an input pin 2, and a connecting wire. The connecting wire connects the output pin 1 and the input pin 2. The frame 7 is provided with a mounting part 3 and a connecting part 5. The mounting part 3 is used to set the input pin 2 and the output pin 1, and the connecting part 5 is used to connect multiple mounting parts 3. An isolation part 4 is provided between the multiple windings. The isolation part 4 is disposed on the frame 7, and the distance from the top wall of the isolation part 4 to the bottom wall of the frame 7 is greater than the distance from the top wall of the input pin 2 and the output pin 1 to the bottom wall of the frame 7.

[0027] Multiple windings are integrated on the transformer frame 7, and then separated by the isolation section 4. This increases the creepage distance between adjacent windings, allowing each winding to withstand higher voltages. Simultaneously, it reduces the risk of high-voltage winding penetration and leakage, lowers the probability of short circuits, and helps maintain the output stability of the multi-output high-voltage transformer. Furthermore, it reduces electromagnetic interference between the multiple windings, making the voltage at input pin 2 less susceptible to interference and resulting in more stable equipment operation.

[0028] Reference Figure 1 as well as Figure 2In this embodiment, the multiple input pins 2 extend in the same direction, the multiple output pins 1 extend in the same direction, and the input pins 2 and output pins 1 extend in opposite directions.

[0029] The pins on the frame 7 are arranged parallel to each other, so that the distance between each pin and the same position between adjacent pins is the same. This helps to reduce electromagnetic interference between them, optimize the distribution of electric field, and reduce the frequency of magnetic field crossing.

[0030] Input pin 2 and output pin 1 are positioned opposite each other on both sides of the frame 7 along its width to reduce the required length of the connecting wires.

[0031] Reference Figure 1 as well as Figure 2 In this embodiment, the isolation part 4 is plate-shaped, and the distance from the isolation part 4 to the input PIN pins 2 on both sides is the same.

[0032] The isolation section 4 is plate-shaped with uniform thickness throughout, ensuring consistent creepage distances between the windings on both sides, which helps maintain the stability of the electric field.

[0033] Reference Figure 1 as well as Figure 2 In this embodiment, the isolation part 4 is integrally connected with the skeleton 7.

[0034] By molding the isolation part 4 and the frame 7 into an integral structure in one injection molding process, the need for additional installation structures for the isolation part 4 can be reduced, making the installation of the isolation part 4 simpler. At the same time, it avoids the connection gap between the isolation part 4 and the frame 7 installation structure, resulting in better isolation effect of the isolation part 4.

[0035] Reference Figure 1 as well as Figure 2 In this embodiment, the size of the isolation part 4 is adaptively adjusted according to the creepage distance requirements.

[0036] When the voltage on the winding is higher, the larger injection-molded isolation section 4 can be selected for isolation to ensure stable isolation.

[0037] Reference Figure 1 as well as Figure 2 In this embodiment, the thickness of the isolation part 4 is 1.3-2mm.

[0038] Reference Figure 1 as well as Figure 2 In this embodiment, the thickness of the isolation part 4 is 1.5 mm or 1.6 mm.

[0039] Among the multiple windings, there may also be a low-voltage section 6 that connects to low voltage. The multiple windings belonging to the low-voltage section 6 do not need to be equipped with an isolation section 4. Only a certain distance needs to be set to meet the creepage requirements, so as to save materials.

[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
