Description

Technical Field

[0001] This utility model specifically relates to a ceramic capacitor core that can eliminate short circuits. Background Technology

[0002] Ceramic capacitors are fundamental components widely used in electronic devices, primarily for storing and releasing charge, filtering, and providing stable voltage in circuits. They typically consist of two or more metal electrodes sandwiched between a ceramic dielectric. The ceramic dielectric not only provides electrical insulation but also determines the capacitor's capacitance and voltage withstand capability.

[0003] In practical applications, ceramic capacitor cores may be affected by environmental factors. In high-humidity environments, moisture may penetrate into the ceramic capacitor core. If the ceramic capacitor core itself has tiny cracks or pores, moisture will condense in these areas, dissolving impurities and forming a conductive solution, thus causing a short circuit. Furthermore, during use, dust entering the ceramic capacitor core can easily absorb moisture from the environment, and the dust may carry impurities such as metal particles, which dissolve in the moisture to form a conductive solution. This creates a conductive path between the electrodes of the ceramic capacitor core or between the electrodes and the ceramic dielectric, also causing a short circuit. A short circuit in the ceramic capacitor core may lead to serious consequences such as equipment failure, data loss, or even hardware damage.

[0004] Therefore, it is necessary to invent a ceramic capacitor core that can eliminate short circuits to solve the above problems. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-3 The ceramic capacitor core shown includes a ceramic sheet 1 at the bottom, and an electrode 2, a sealing glass glue 3, an electrode 4 and a ceramic elastic diaphragm 5 are sequentially mounted on the ceramic sheet 1 from top to bottom.

[0028] Specifically, electrode 1 2 and electrode 2 4 are respectively disposed on both sides of the sealing glass glue 3, and the sealing glass glue 3 is provided with receiving grooves 31 on both sides to accommodate electrode 1 2 and electrode 2 44. The sealing glass glue 3 has a placement hole 32 in the middle and multiple air grooves 33 on the sealing glass glue 3. The ceramic thick sheet 1 and ceramic elastic film 5 are attached to the upper and lower sides of the sealing glass glue 3.

[0029] Specifically, the cross-sectional dimensions of the ceramic sheet 1, the sealing glass glue 3, and the ceramic elastic diaphragm 5 are matched.

[0030] In this embodiment, the ceramic sheet 1 at the bottom provides a stable base to support the components on it. Electrode 2, as a thick sheet electrode, is located on one side of the sealing silicone sealant 3, and electrode 4, as a thin sheet electrode, is located on the other side of the sealing silicone sealant 3. The two electrodes are placed in the receiving grooves 31 of the sealing silicone sealant 3 to ensure their fixation and electrical isolation. The sealing silicone sealant 3 provides electrical insulation between electrode 2 and electrode 4. The air grooves 33 therein can store rarefied air, increasing the structural ventilation and aiding in thermal management. A ceramic elastic diaphragm 5 covers the top, matching the dimensions of the ceramic sheet 1 and the sealing silicone sealant 3, providing additional protection and flexible support for the entire structure.

[0031] In this embodiment, the sealing silicone sealant 3 forms a robust protective barrier, preventing moisture, dust, chemicals, and other external environmental contaminants from entering the capacitor. This helps ensure the capacitor's stability and reliability. Furthermore, the silicone sealant possesses excellent electrical insulation properties, effectively preventing electrical short circuits or leaks between the capacitor's internal electrodes and the external environment. Simultaneously, the sealing silicone sealant enhances the capacitor's mechanical strength, making it more resistant to external mechanical stress and impacts, thereby improving the capacitor's durability.

[0032] Reference Figure 2-3 Electrostatic shielding electrode 6 and electrostatic shielding electrode 7 are respectively provided on the outer side of electrode 1 2 and electrode 2 4. Electrode 1 2 is a thick sheet electrode and an active electrode 21 is led out. A detection electrode 61 is led out from electrostatic shielding electrode 6. Electrode 2 4 is a thin sheet electrode and an active electrode 41 is led out from electrostatic shielding electrode 7. A detection electrode 71 is led out from electrostatic shielding electrode 7.

[0033] In this embodiment, the sheet electrodes allow the capacitor to increase its surface area by stacking the sheets, thereby achieving a higher capacitance value within a smaller volume. Furthermore, because the sheet electrodes can be manufactured and arranged with great precision, they facilitate precise control of the capacitor's capacitance value to meet specific electronic device requirements. The parallel arrangement of the sheet electrodes in the ceramic dielectric helps reduce the capacitor's internal resistance and inductance, improving frequency response and reducing energy loss.

[0034] In this embodiment, the thick sheet electrode enhances the overall structural strength of the capacitor, making it more durable and resistant to damage. Due to its larger volume, the thick sheet electrode can accommodate larger currents, making it suitable for high-power applications. The larger volume of the thick sheet electrode helps disperse the heat generated during capacitor operation, thereby improving overall thermal management and stability. The combination of these two factors allows the capacitor to withstand higher currents while maintaining a high capacitance value and improving structural stability.

[0035] In this embodiment, electrostatic shielding electrode 6 and electrostatic shielding electrode 7 are located close to electrodes 2 and 4, respectively, to provide electromagnetic interference shielding. Their dimensions are designed differently from the dimensions of the mounting hole 32 to ensure proper shielding effectiveness and component compatibility.

[0036] Specifically, the ceramic sheet 1 has three pin holes 11, and the sealing glass glue 3 has three corresponding connection holes 34. The source electrode 1 21 and the probe electrode 1 61 and the source electrode 2 41 and the probe electrode 2 71 are respectively located on different pin holes 11.

[0037] Specifically, the size of electrostatic shielding electrode 6 is larger than the size of the mounting hole 32, and the size of electrostatic shielding electrode 7 is smaller than the size of the mounting hole 32. That is, the sizes of the upper and lower receiving grooves 31 are inconsistent, and the depths of the upper and lower receiving grooves 31 match those of electrode 2, electrode 4, electrostatic shielding electrode 6, and electrostatic shielding electrode 7.

[0038] Specifically, the multiple air slots 33 are all arc-shaped slots, and are concentrically distributed on the outside of the mounting hole 32, with the number gradually decreasing from the inside to the outside.

[0039] Specifically, electrode 2 and electrode 4 are placed inside the mounting hole 32, with a certain space between them.

[0040] In this embodiment, the good electrical isolation between electrodes and between electrodes and the outside world greatly reduces the risk of short circuits; the combined use of sealing glass glue and ceramic sheets, as well as the precise placement of electrodes, ensures the stability and long-term reliability of the entire capacitor; the design of electrostatic shielding electrodes effectively reduces electromagnetic interference, enabling the capacitor to work stably in complex electromagnetic environments; and the use of air slots and ceramic elastic diaphragms in the design helps maintain the integrity of internal components and extend the service life of the capacitor.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
