Description

A hybrid capacitor with protective function Technical Field

[0001] This utility model relates to the field of capacitor technology, specifically to a hybrid capacitor with protective functions. Background Technology

[0002] Hybrid capacitors are a new type of energy storage device that combines the characteristics of traditional capacitors and batteries. They typically have higher operating voltage, capacitance, and energy density, while maintaining lower self-discharge and standby current. The construction of hybrid capacitors usually includes an anode made of graphite and lithium, as well as different electrolytes, thus possessing excellent performance and improved stability compared to general capacitors. They are widely used in various fields of the electronics industry.

[0003] Based on this, a search on the patent website revealed that Chinese patent application number CN201821061817.X discloses a hybrid compensation capacitor;

[0004] It is evident that the aforementioned patent application has shortcomings: the existing hybrid capacitor has a relatively large ESL, resulting in high insertion loss in high-frequency and decoupling circuits. When the hybrid capacitor is used in a location with strong signal interference, it is prone to causing high inductive interference to the capacitor, thereby affecting the normal use of the capacitor.

[0005] To address the aforementioned problems, a hybrid capacitor with protective functions is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a hybrid capacitor with protective function. By using this device, the problems of existing hybrid capacitors having a large ESL, resulting in large insertion loss in high-frequency and decoupling circuits, and causing high inductive interference to the capacitor when used in locations with strong signal interference, thus affecting the normal use of the capacitor.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a hybrid capacitor with protective function, comprising a connecting base and ceramic plates disposed on the top of the connecting base, wherein there are two sets of ceramic plates, a capacitor plate one is disposed between the two sets of ceramic plates, and a capacitor plate two is disposed between the two sets of ceramic plates. A connecting groove is provided on the top of the connecting base, and a heat dissipation vent is provided on the outer side of the connecting base.

[0008] Preferably, the two sets of capacitor plates one and the two sets of capacitor plates two are arranged alternately, and the capacitor plates one and two are provided with mounting grooves.

[0009] The above-described structure, with its mounting slots, allows the electrode plates to be mounted on the capacitor plates, improving performance.

[0010] Preferably, the two sets of capacitor sheet one and the two sets of capacitor sheet two are fixedly connected between the two sets of ceramic sheets.

[0011] The above-described structure, through the placement of ceramic plates, enables the overall capacitor to form a stable structure, making it suitable for various scenarios.

[0012] Preferably, an inner electrode plate is fixedly connected inside the mounting groove, and an outer electrode plate is fixedly connected outside the inner electrode plate.

[0013] By adopting the above-mentioned structural design and setting the inner and outer electrode plates, the impedance of the capacitor at high frequencies is significantly reduced, making the overall capacitor more suitable for GHz-level high-frequency filtering and decoupling scenarios.

[0014] Preferably, multiple sets of outer electrode sheets are provided, and the outer electrode sheets extend to the outer side of the ceramic sheet.

[0015] By adopting the above-described structure and setting the outer electrode plate, the capacitor structure can be adapted for use in high-frequency communication equipment.

[0016] Preferably, a sealing ring is fixedly connected inside the connecting groove, and a set of ceramic sheets slides in conjunction with the connecting groove.

[0017] The design of the above structure, with the addition of connecting slots, allows related components to be connected to the slots, making it convenient to use.

[0018] Preferably, a second sealing ring is fixedly connected to the outer side of a group of ceramic sheets, and the second sealing ring matches the first sealing ring.

[0019] By adopting the above-described structure and using sealing ring one and sealing ring two, the stability of the overall capacitor structure is improved.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This application proposes a hybrid capacitor with protective function, which solves the problem that existing hybrid capacitors have a relatively large ESL, resulting in high insertion loss in high-frequency and decoupling circuits. Furthermore, when used in locations with strong signal interference, the hybrid capacitor is prone to high inductive interference, affecting its normal operation. When using the capacitor, the connection base can be installed in a designated position. Due to the interleaved arrangement of capacitor plates one and two and the extension of the outer electrode plate to the outside of the ceramic plate, the impedance of the capacitor at high frequencies is significantly reduced, making the overall capacitor more suitable for GHz-level high-frequency filtering and decoupling scenarios. Simultaneously, the smaller the ESL, the lower the resonant frequency. The higher the ESL, the lower the impedance of the capacitor, maintaining low impedance characteristics across a wider frequency band, reducing high-frequency noise interference, and suppressing signal ringing and distortion. Low ESL capacitor banks shorten the current loop, reducing the impact of parasitic inductance on high-speed signals and avoiding signal reflection and waveform distortion caused by inductive effects. Secondly, the reduced ESL improves the charging and discharging speed of the capacitor, making the circuit respond more quickly to transient current changes. Finally, by using a two-layer ceramic plate configuration, the ESL is reduced to below .nH by shortening the electrode spacing and optimizing the current path, while simultaneously achieving high capacitance density. This enables the capacitor structure to be suitable for high-frequency communication equipment and improves the overall structural stability.

[0022] 2. The hybrid capacitor with protective function proposed in this application solves the problem that most existing hybrid capacitors have a simple structure and often lack effective heat dissipation methods, which easily leads to overheating and damage of the capacitor during use. During use, the heat dissipation port on the outside of the connecting base can dissipate the heat generated by the ceramic plate. At the same time, the sealing ring two at the bottom of the ceramic plate and the sealing ring one inside the connecting groove improve the connection stability between the ceramic plate and the connecting base, further preventing damage to the ceramic plate and its accessories. This achieves the effect of improving the overall protection of the capacitor and increasing its service life. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0030] Referring to Figures 1-3, a hybrid capacitor with protective function includes a connecting base 1 and a ceramic plate 11 disposed on the top of the connecting base 1. The ceramic plate 11 is provided in two sets, with a capacitor plate 111 disposed between the two sets of ceramic plates 11 and a capacitor plate 112 disposed between the two sets of ceramic plates 11. A connecting groove 13 is provided on the top of the connecting base 1, and a heat dissipation vent 131 is provided on the outer side of the connecting base 1.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] To address the issue of existing hybrid capacitors having a large ESL, resulting in high insertion loss in high-frequency and decoupling circuits, and causing significant inductive interference when used in locations with strong signal interference, thus affecting normal operation, the following solution is disclosed (see Figures 1-3). Two sets of capacitor plates 111 and 112 are staggered. Mounting slots 12 are provided on both capacitor plates 111 and 112. The two sets of capacitor plates 111 and 112 are fixedly connected between two ceramic plates 11. An inner electrode plate 121 is fixedly connected inside the mounting slot 12, and an outer electrode plate 122 is fixedly connected to the outside of the inner electrode plate 121. Multiple outer electrode plates 122 are provided, extending to the outside of the ceramic plates 11. When using the capacitor, the connecting base 1 can be installed in the designated position. Since capacitor plates 111... The interleaved arrangement of capacitor plates 112 and the extension of outer electrode plate 122 to the outside of ceramic plate 11 significantly reduces the impedance of the capacitor at high frequencies, making the overall capacitor more suitable for GHz-level high-frequency filtering and decoupling scenarios. At the same time, the lower the ESL, the higher the resonant frequency, and the capacitor maintains low impedance characteristics over a wider frequency band, reducing high-frequency noise interference and suppressing signal ringing and distortion. The low ESL capacitor array reduces the impact of parasitic inductance on high-speed signals by shortening the current loop, avoiding signal reflection and waveform distortion caused by inductance effects. Secondly, the reduction of ESL improves the charging and discharging speed of the capacitor, making the circuit respond more quickly to transient current changes. Finally, the use of two sets of ceramic plate 11 sandwich layers reduces the ESL to below 0.1nH by shortening the electrode spacing and optimizing the current path, while achieving high capacitance density. This enables the capacitor structure to be used in high-frequency communication equipment and improves the stability of the overall structure.

[0034] Example 2:

[0035] To address the problem that most existing hybrid capacitors have simple structures and often lack effective heat dissipation methods, leading to overheating and damage during use, the following solution is disclosed. Please refer to Figures 2 and 4 for details. A sealing ring 132 is fixedly connected inside the connecting groove 13. A set of ceramic plates 11 slides within the connecting groove 13. A second sealing ring 133 is fixedly connected to the outer side of the ceramic plates 11, matching the first sealing ring 132. During use, the heat dissipation vent 131 on the outer side of the connecting base 1 dissipates the heat generated by the ceramic plates 11. Simultaneously, the second sealing ring 133 at the bottom of the ceramic plates 11 and the first sealing ring 132 inside the connecting groove 13 improve the connection stability between the ceramic plates 11 and the connecting base 1, further preventing damage to the ceramic plates 11 and their accessories. This improves the overall capacitor protection effect and extends its service life.
