Description

TECHNICAL FIELD

[0001] The application relates to the technical field of electronic components, in particular to a magnetic core reinforced vertical inductor. BACKGROUND

[0002] A magnetic core is a device used for electromagnetic transmission and is commonly used in electronic equipment. In the application of photovoltaic and automotive products, the magnetic core is usually used in the structure of a converter and an inverter.

[0003] The prior art (publication number: CN219873079U) discloses a reinforced magnetic core and a vertical inductor, which are used for the process of magnetic core potting glue. The reinforced magnetic core comprises a first magnetic core, a first skeleton and a soft structure. The first magnetic core comprises side edge columns, a middle column magnetic core and two magnetic yokes. The two ends of the side edge columns are connected to one side of the two magnetic yokes, and the middle column magnetic core is arranged between the two magnetic yokes. The middle column magnetic core is provided with a wire package. The first skeleton is a hollow ring-shaped column, and the first skeleton is sleeved on the middle column magnetic core and located between the two magnetic yokes. A plurality of first through holes are formed in the first skeleton. The soft structure is attached to the wire package and located between the wire package and the side edge column.

[0004] The above-mentioned comparative document points out that by arranging multiple protection structures on the magnetic core, the stress of the potting glue outside the magnetic core is dispersed by the first skeleton, and the stress inside the magnetic core is avoided by the soft structure, thereby improving the overall strength of the magnetic core and avoiding cracking and damage of the magnetic core. However, the magnetic core part of the device is hard connected with the magnetic yoke and the side edge column, which can easily cause high magnetic stress and cracking during use. Utility model content

[0005] In view of the deficiencies of the prior art, the application provides a magnetic core reinforced vertical inductor, which has the advantages of protecting the magnetic core and solving the problem that the stress of the potting glue outside the magnetic core is dispersed by the first skeleton, and the stress inside the magnetic core is avoided by the soft structure, thereby improving the overall strength of the magnetic core and avoiding cracking and damage of the magnetic core. However, the magnetic core part of the device is hard connected with the magnetic yoke and the side edge column, which can easily cause high magnetic stress and cracking during use.

[0006] To achieve the above-mentioned purpose, the application provides the following technical scheme: a magnetic core reinforced vertical inductor, comprising a first side edge column and a second side edge column, the second side edge column is internally fixedly connected with four first rubber columns arranged in a rectangular array, two groups of the four first rubber columns are fixedly connected with a lower magnetic yoke, the lower magnetic yoke is fixedly connected with a lower magnetic core at the upper end, the lower magnetic core is fixedly provided with a plurality of second rubber columns arranged in a ring array on the inner wall of the upper end, and the second rubber columns are fixedly connected with a mounting ring at the end away from the lower magnetic core.

[0007] The first side column is internally fixedly connected with four third rubber columns arranged in a rectangular array, two groups of the four third rubber columns are fixedly connected with an upper magnetic yoke, the bottom end of the upper magnetic yoke is fixedly connected with an upper magnetic core, and the bottom end of the upper magnetic core is fixedly connected with a mounting block.

[0008] Through the above scheme, by arranging the first rubber column, the second rubber column and the third rubber column, the magnetic core can be effectively protected, and displacement or damage under vibration or impact can be avoided. The elastic properties of the rubber column not only provide good buffering effect, but also enhance the overall structural stability of the inductor. The design of the mounting ring and the mounting block enables the upper magnetic core and the lower magnetic core to be quickly positioned and fixed during installation, simplifying the installation steps. Due to the layout design of the magnetic core and the rubber column, the inductor can form a good heat dissipation channel during work, effectively reducing the working temperature of the inductor and preventing performance degradation or damage due to overheating.

[0009] Further, the first side column and the second side column are fixedly connected with a bobbin.

[0010] Through the above scheme, the bobbin is fixedly connected between the first side column and the second side column, which not only provides a stable support structure for the inductor, but also makes the structure of the entire inductor more compact. This design helps to reduce the size of the inductor, making it easier to integrate into various electronic devices.

[0011] Further, the bobbin outer wall is fixedly connected with a coil.

[0012] Through the above scheme, the bobbin provides a support structure for the coil, keeping it in a neat shape and position, reducing performance degradation caused by deformation or displacement of the coil.

[0013] Further, the bottom end of the bobbin is fixedly connected with two mounting seats, and the bottom end of each mounting seat is fixedly connected with a plurality of straightly distributed pins.

[0014] Through the above scheme, the design of the mounting seat makes the installation and disassembly of the inductor on the circuit board more simple and convenient. Users can connect the pins to the circuit board through direct welding or plug-in connection to achieve quick installation of the inductor.

[0015] Further, the coil outer wall is fixedly connected with an insulating tape.

[0016] Through the above scheme, the main function of the insulating tape is to provide electrical insulation to ensure that the coil does not come into electrical contact with other conductive parts, thereby avoiding the risk of short circuit or electric shock. This greatly enhances the safety and reliability of the inductor.

[0017] Further, the first side column and the second side column outer wall are fixedly connected with an insulating tape.

[0018] Through the above scheme, the first side edge column and the second side edge column are fixed by the insulating adhesive tape.

[0019] Further, the mounting block is slidingly arranged inside the mounting ring.

[0020] Through the above scheme, the slidingly arranged mounting block makes the assembly process of the inductor more convenient, and also facilitates subsequent maintenance operations.

[0021] Further, the lower magnetic core and the upper magnetic core are both slidingly arranged inside the bobbin.

[0022] Through the above scheme, the bobbin is fixed by the lower magnetic core and the upper magnetic core.

[0023] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0024] The vertical inductor with reinforced magnetic core can effectively protect the magnetic core from displacement or damage under vibration or impact. The elastic properties of the rubber columns not only provide good buffering effect, but also enhance the overall structural stability of the inductor. The design of the mounting ring and the mounting block enables the upper magnetic core and the lower magnetic core to be quickly positioned and fixed during the installation process, simplifying the installation steps. Due to the layout design of the magnetic core and the rubber columns, the inductor can form a good heat dissipation channel during operation, effectively reducing the working temperature of the inductor and preventing performance degradation or damage due to overheating.
