Description

Technical Field

[0001] The utility model relates to the technical field of ceramic capacitors, in particular to a moisture-resistant and moisture-proof chip ceramic capacitor. Background Art

[0002] Capacitors are components that store electrical charge and potential energy, and there are many types. Among them, small ceramic capacitors are made by extruding high dielectric constant capacitor ceramics into round tubes, discs or disks as dielectrics, and using the sintering method to plate silver on the ceramics as electrodes;

[0003] The known authorized utility model (Announcement No.: CN214848221U) discloses a moisture-resistant and moisture-proof chip ceramic capacitor, including a ceramic capacitor body, two leads are fixedly arranged at the bottom of the ceramic capacitor body, a protective shell is fixedly arranged on the outside of the ceramic capacitor body, two first protective cylinders are fixedly arranged on both sides of the bottom of the protective shell, the two first protective cylinders are respectively fixedly sleeved on the tops of the two leads, the bottom ends of the two first protective cylinders are respectively provided with two second protective cylinders through a clamping assembly, the two second protective cylinders are respectively movably sleeved on the bottoms of the two leads, the clamping assembly includes four mounting slots, four coil springs, four levers and four insertion rods, the beneficial effect of the utility model is: the lever provided in the movable clamping assembly enables the coil spring to drive the insertion rod to engage with the card slot or to disengage from the card slot to remove the second protective cylinder for use, so as to avoid the lead wires being exposed to the outside and being easily affected by moisture, rust or dust, which is inconvenient to use;

[0004] When the device is in use, although it can prevent the lead wire from being exposed to moisture, rust or dust, it needs to be disassembled separately when disassembling the second protective tube, and the two second protective tubes cannot be disassembled at the same time. This design increases the complexity and time cost of the disassembly operation. At the same time, our R&D department is considering further optimizing the design so that the two second protective tubes can be disassembled at the same time to improve the convenience and efficiency of the operation. The specific optimization directions can include the following aspects:

[0005] Improved snap-fit ​​assembly design: A snap-fit ​​assembly that can simultaneously control two second protective tubes can be designed. For example, two levers can be connected through a linkage mechanism so that when one lever is operated, the other lever will also move synchronously, thereby achieving simultaneous disassembly and assembly of the two second protective tubes.

[0006] Optimize the installation slot and plug-in rod structure: Consider improving the shape, size or material of the installation slot and the plug-in rod to improve the matching accuracy and stability between them, thereby ensuring smooth engagement or disengagement during disassembly and assembly.

[0007] Adding auxiliary tools: A special auxiliary tool can be designed to simultaneously operate the disassembly and assembly of the two second protective tubes. This tool can simplify the operation process and reduce the difficulty and complexity of the operation.

[0008] Improve the fixing method of the second protective tube: In addition to the snap-fit ​​assembly, you can also consider improving the fixing method of the second protective tube, such as using a magnetic connection or a quick-release structure, so that the disassembly and assembly operations can be performed faster and more conveniently.

[0009] Through the above optimization measures, the practicality and convenience of the moisture-resistant and moisture-proof chip ceramic capacitor can be further improved, and the operating difficulty and time cost of the user during use can be reduced. To this end, a moisture-resistant and moisture-proof chip ceramic capacitor is proposed. Utility Model Content
