Description

TECHNICAL FIELD

[0001] The utility model relates to the field of power electronics, concretely is a transformer and inductor integrated potting structure. BACKGROUND

[0002] In today's power electronics field, inductors as key components play a crucial role in solar photovoltaic inverters, charging piles, uninterruptible power supplies (UPS) and energy storage devices. Their demand continues to grow, and technology is becoming increasingly mature. As these application fields continue to demand higher performance and reliability, the market demand for energy storage inductors has increased significantly, and product design and manufacturing processes have reached a high level, resulting in limited further optimization space in terms of cost.

[0003] In the traditional assembly process of transformers and inductors, there are often problems such as complicated steps and low efficiency, which not only increases production costs, but also makes it difficult to ensure product consistency and stability. In addition, the traditional assembly method often fails to fully utilize the internal space of the product, resulting in low space utilization, further limiting the improvement of product performance and the reduction of cost. Moreover, traditional transformers usually do not undergo potting treatment, which makes them susceptible to physical damage such as vibration, impact or moisture during harsh environments or long-term operation, thereby affecting their electrical performance and stability. The exposed design of the transformer also makes it more susceptible to external pollution and corrosion, shortening its service life and increasing maintenance costs.

[0004] Furthermore, although inductors sometimes use separate potting methods to improve their protection level, this approach often results in low space utilization. After the inductor is individually potted, it usually needs to be connected to other circuit elements through a flying wire, which not only increases the complexity and cost of assembly, but also occupies valuable circuit board space.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example:

[0022] like Figs. 1-2 As shown, this utility model provides an integrated potting structure for a transformer and an inductor.

[0023] The device includes a housing 1, a transformer 2, and an inductor 3. The housing 1 has a positioning groove 4, which is set in several groups and evenly spaced. The transformer 2 and the inductor 3 are both located in the positioning groove 4. The housing 1 has a positioning post 5, which is connected to a PCB board. The bottom of the positioning groove 4 has anti-slip texture to enhance the stability of the transformer 2 and the inductor 3 within the positioning groove 4.

[0024] This application simplifies the assembly process and improves production efficiency by integrating the transformer 2 and the inductor 3 into a single housing 1 and achieving integrated potting. It not only saves space but also improves the overall structural strength and stability of the product. Integrated potting means that the transformer 2 and the inductor 3 are integrated into the same housing 1, forming a compact whole. This makes the connection between the transformer 2 and the inductor 3 more direct and tight, eliminating the need for remote connection via flying wires.

[0025] After inductor 3 is potted separately, it usually needs to be led out through a flying wire to connect with other circuit components. This not only increases the complexity of assembly, but also occupies circuit board space. The integrated design saves the space occupied by the flying wire by integrating transformer 2 and inductor 3 into the same housing 1 and connecting them directly, thereby improving the space utilization rate.

[0026] The positioning groove 4 on the housing 1 is used to accurately place the transformer 2 and the inductor 3, while the anti-slip texture on the bottom of the positioning groove 4 enhances the stability of these components in the groove and prevents displacement under vibration or impact conditions.

[0027] The number of positioning posts 5 matches the number of mounting holes on the PCB board, and the end of each positioning post 5 is threaded, with a nut connected to the thread, so as to securely connect with the PCB board and improve the reliability and shock resistance of the overall structure.

[0028] The positioning column 5 on the shell 1 matches the mounting hole on the PCB board, and is connected through threads and fastened by a nut, thereby realizing the stable connection of the shell 1 and the PCB board, improving the reliability and shock resistance of the overall structure.

[0029] The shell 1 is provided with a plurality of mounting holes 6, which are uniformly arranged between the mounting holes 6, thereby facilitating the installation of the shell 1.

[0030] The connection between the PCB board and the positioning column 5 is provided with a buffer gasket, which is used to absorb and disperse the stress between the PCB board and the shell 1, thereby preventing the connection from loosening or being damaged due to vibration or impact.

[0031] The connection between the PCB board and the positioning column 5 is provided with a buffer gasket, which is used to absorb and disperse the stress between the PCB board and the shell 1, thereby preventing the connection from loosening or being damaged due to vibration or impact.

[0032] The inner wall of the shell 1 is provided with a heat-conducting layer, which is used to effectively disperse the heat generated by the transformer 2 and the inductor 3 during operation.

[0033] The heat-conducting layer on the inner wall of the shell 1 helps to disperse the heat generated by the transformer 2 and the inductor 3 during operation, thereby improving the heat dissipation performance of the product and prolonging the service life.

[0034] The shape and size of the positioning groove 4 are customized according to the specific specifications of the transformer 2 and the inductor 3, thereby ensuring that each component can be tightly fitted in the positioning groove 4.

[0035] The shell 1 is provided with a plurality of reinforcing ribs 7 on the peripheral surface, which are distributed along the circumference of the shell 1 to enhance the structural strength and rigidity of the shell 1.

[0036] The reinforcing ribs 7 on the peripheral surface of the shell 1 enhance the structural strength and rigidity of the shell 1, thereby further improving the shock resistance and durability of the product.

[0037] Working steps

The mounting hole 6 on the PCB board is aligned with the positioning column 5 on the shell 1, and then a nut is threaded and tightened, realizing the stable connection of the PCB board and the shell 1. A buffer gasket is installed at the connection between the PCB board and the positioning column 5 to absorb and disperse stress.

[0039] The assembled transformer 2 and inductor 3 components are subjected to a potting process, and a potting material is used to fill the inside of the shell 1, thereby ensuring that the transformer 2 and the inductor 3 are completely wrapped, improving the protection level and stability.

[0040] The present application greatly simplifies the assembly process, reduces the assembly steps, thereby improving the production efficiency, the shape and size of the positioning groove 4 are customized according to the specific specifications of the transformer 2 and the inductor 3, ensuring that each component can be closely fitted in the positioning groove 4, which not only improves the assembly accuracy, but also ensures the consistency and stability of the product.

[0041] The anti-skid lines provided at the bottom of the positioning groove 4 enhance the stability of the transformer 2 and the inductor 3 in the positioning groove 4, reduce displacement or loosening caused by vibration or impact, the number of positioning columns 5 matches the number of mounting holes 6 on the PCB, and the ends of the positioning columns 5 are provided with threads and connected with nuts, so that the connection between the PCB and the shell 1 is more stable, improving the reliability and shock resistance of the overall structure.
