Description

Technical Field

[0001] This utility model relates to the field of filter capacitor technology, specifically to a high-performance, small-volume filter capacitor. Background Technology

[0002] High-performance, small-size filter capacitors are key components in modern electronic devices for achieving efficient filtering and stable power supply. Their technological development is continuously advancing towards higher performance, smaller size, lower loss, and higher reliability. Filter capacitors smooth voltage fluctuations in circuits, suppress high-frequency noise, and ensure the stability of power output by storing and releasing charge. In applications such as switching power supplies, DC-DC converters, and signal processing circuits, the performance of filter capacitors directly affects the efficiency and reliability of the system. High-performance, small-size filter capacitors are a crucial support for the development of electronic technology, and their technological advancements will drive electronic devices towards higher performance, smaller size, and lower power consumption. In the future, with continuous innovation in materials science, manufacturing processes, and packaging technologies, filter capacitors will play a crucial role in even more fields.

[0003] According to the announcement number CN220672401U, a filter capacitor includes an end cap. A protective mechanism is provided on one side of the end cap. The protective mechanism includes a round rod, a sleeve plate, and a nut. One end of the round rod is fixedly connected to one side of the end cap. The outer wall of the round rod is sleeved with the inner wall of the sleeve plate. The outer wall of the round rod is threadedly connected to the inner wall of the nut. The outer wall of the sleeve plate is fitted against one side of the nut. By fitting a sleeve plate onto the outer wall of a round rod, the bolts rotate, fixing the sleeve plate to the outer wall of the round rod. Simultaneously, the sleeve plate engages with the outer wall of the capacitor body. The round rod prevents the outer wall of the capacitor body from impact, and the sleeve plate protects the corners of the capacitor body from dents after impact, making the capacitor less susceptible to damage and thus extending its service life. However, this protective mechanism is cumbersome to install using bolts, requiring auxiliary tools for disassembly and maintenance. Therefore, improving existing filter capacitors and designing a new high-performance, small-volume filter capacitor to address these technical shortcomings and enhance the overall practicality of the filter capacitor is of paramount importance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] A high-performance, small-volume filter capacitor includes a capacitor body 1, a protective shell 2 on the outside of the capacitor body 1, a connecting cover 3 on the top of the protective shell 2, multiple sets of connecting components 4 on the top inside the protective shell 2, and a reinforcing component 5 inside the protective shell 2 and below the connecting components 4.

[0028] The connecting component 4 is used to install the capacitor body 1 and the protective shell 2 in conjunction with the connecting cover 3. The connecting component 4 consists of a moving block 6, two sets of fixing rods 7, a sliding rod 8 and a compression spring 9. The moving block 6 is slidably connected to the top inside the protective shell 2. Both sets of fixing rods 7 are fixedly connected to the outside of the moving block 6. The sliding rod 8 is fixedly connected to the top inside the protective shell 2 and is located inside the moving block 6. The compression spring 9 is sleeved on the outside of the sliding rod 8 and is located on the outside of the moving block 6.

[0029] Reinforcing component 5 is used to increase the deformation resistance of the protective shell 2.

[0030] Furthermore, the movable block 6 extends to the outside of the protective shell 2 and is fixedly connected to the pull rod 10. The movable block 6 and the sliding rod 8 are slidably connected. The two ends of the compression spring 9 are fixedly connected to the movable block 6 and the protective shell 2 respectively. Pulling the pull rod 10 can drive the movable block 6 to move, so that the fixed rod 7 can move. The compression spring 9 can drive the movable block 6 to move.

[0031] The fixing rod 7 and the protective shell 2 are slidably connected. The top of the protective shell 2 is provided with fixing grooves 11 on all four sides. The bottom of the connecting cover 3 is fixedly connected with multiple sets of fixing blocks on all four sides. The connecting cover 3 is connected to the fixing grooves 11 through the fixing blocks. Multiple sets of mounting grooves are provided inside the fixing blocks. The internal structure size of the mounting grooves corresponds to the external structure size of the fixing rod 7. The fixing blocks are connected to the fixing rod 7 through the mounting grooves, connecting the connecting cover 3 and the protective shell 2, so that the fixing blocks are moved into the inside of the fixing grooves 11. The moving block 6 is moved by the compression spring 9, so that the fixing rod 7 is inserted into the inside of the mounting groove and is limited to the fixing block, so that the connecting cover 3 can be installed.

[0032] Furthermore, both ends of the sliding rod 8 are fixedly connected to limit balls 12. The moving block 6 has two sets of limit grooves 13 at the end near the limit balls 12. The moving block 6 is connected to the limit balls 12 through the limit grooves 13. When the fixed rod 7 is moved out of the inside of the mounting groove, the displacement of the moving block 6 drives the two sets of limit grooves 13 to move and connect with the limit balls 12, thereby limiting the moving block 6 and moving the fixed rod 7 out of the inside of the fixed groove 11, which facilitates the disassembly of the connecting cover 3.

[0033] Furthermore, the reinforcing component 5 consists of multiple sets of reinforcing rings 14, multiple sets of reinforcing rods 15, and multiple sets of supporting bars 16. The multiple sets of reinforcing rings 14 are all fixedly connected to the inside of the protective shell 2 and located below the connecting component 4. The multiple sets of reinforcing rods 15 are all located between the multiple sets of reinforcing rings 14, and the multiple sets of supporting bars 16 are all located between the multiple sets of reinforcing rings 14 and the multiple sets of reinforcing rods 15. When the capacitor body 1 is in use, the reinforcing component 5 increases the deformation resistance of the protective shell 2, so that the protective shell 2 can effectively protect the capacitor body 1.

[0034] Furthermore, multiple sets of reinforcing rings 14, multiple sets of reinforcing rods 15, and multiple sets of support bars 16 are fixedly connected to each other. The two sets of reinforcing rods 15 and the two sets of reinforcing rings 14 are designed in a triangular structure. The reinforcing rings 14, reinforcing rods 15, and support bars 16 are fixedly connected to each other to form a stable support structure. In particular, the triangular structure between the two sets of reinforcing rods 15 and the two sets of reinforcing rings 14 has high mechanical stability and can effectively disperse and absorb external impact forces to prevent deformation of the protective shell 2. The reinforcing components 5 as a whole improve the strength and rigidity of the protective shell 2. Even if the capacitor body 1 works in a complex or harsh environment, it can ensure that the capacitor body 1 is not damaged, thereby extending the service life of the filter capacitor.

[0035] In this embodiment, the specific implementation scenario is as follows: When it is necessary to install the capacitor body 1, the capacitor body 1 is placed inside the protective shell 2, causing the fixing block to move into the fixing groove 11. When the fixing block is fully inserted into the fixing groove 11 and reaches the position corresponding to the fixing rod 7, due to the elastic restoring force of the compression spring 9, the moving block 6 drives the fixing rod 7 to move towards the fixing block until the fixing rod 7 is fully inserted into the mounting groove of the fixing block. After the fixing rod 7 and the fixing block are fully engaged, the connecting cover 3 is securely fixed to the protective shell 2. The presence of the compression spring 9 not only provides sufficient installation force but also ensures that the connecting assembly 4 has a certain buffering capacity when subjected to external impact, increasing... The overall durability of the filter capacitor is improved by the interconnected reinforcing ring 14, reinforcing rod 15, and support bar 16, forming a stable support structure. In particular, the two sets of reinforcing rods 15 and the two sets of reinforcing rings 14 are designed in a triangular structure, which has high mechanical stability and can effectively disperse and absorb external impact forces to prevent deformation of the protective shell 2. The reinforcing component 5 improves the overall strength and rigidity of the protective shell 2, ensuring that the capacitor body 1 is not damaged even when working in complex or harsh environments, thereby extending the service life of the filter capacitor. Compared with existing filter capacitors, this utility model improves the overall practicality of the filter capacitor through design.
