DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The following is combined with Figure 1-7 To further explain this application in detail,

[0029] The embodiment of the present application discloses a vertically assembled solid-state capacitor, comprising a core package 1, a sealing rubber cover 6, an insulating sleeve 18, and an aluminum shell 11. The two pin terminals 2 on the core package 1 are respectively connected to the positive pin 3 and the negative pin 4, and the two pin terminals 2 are outer-mounted with silicone sealing pads 5; the sealing rubber cover 6 is provided with two slots 7 for plugging and positioning the silicone sealing pads 5, and the top of the sealing rubber cover 6 is provided with an inner ring 8 and an outer ring 9 integrally formed with the core package 1; the insulating sleeve 18 is sleeved on the outer side of the core package 1 and the insulating sleeve 18 is inserted into the annular groove 10 surrounded by the inner ring 8 and the outer ring 9; the aluminum shell 11 is sleeved on the outer side of the insulating sleeve 18 and the sealing rubber cover 6 and is packaged together with the sealing rubber cover 6.

[0030] The core package 1, the sealant cover 6, the insulating sleeve 18 and the aluminum shell 11 of the capacitor are tightly combined, so that the entire capacitor structure is stable and not easy to be damaged. The core package 1 is wrapped in the space surrounded by the insulating sleeve 18 and the sealant cover 6 by plugging and combining the insulating sleeve 18 and the sealant cover 6. The insulating sleeve 18 replaces the traditional insulating paper to separate the core package 1 and the aluminum shell 11. The sealant cover 6 is connected to an insulating sleeve 18 on the outer side of the core package 1, which can provide better mechanical protection and more stable insulation performance. At the same time, this method may not increase the volume and cost of the capacitor too much, because the existing sealant cover 6 can be used as a carrier of the insulating sleeve 18;

[0031] The design of the silicone seal 5 and the sealant cover 6 makes the capacitor have good sealing performance, which can prevent external moisture, dust and other impurities from entering the capacitor, thereby ensuring the long-term stable operation of the capacitor. The vertical assembly design makes the capacitor easy and convenient to install. At the same time, the design of the slot 7 also enables the silicone seal 5 to be accurately inserted into the sealant cover 6, improving the installation efficiency. The packaging structure of the aluminum shell 11, the insulating sleeve 18 and the sealant cover 6 can effectively prevent the occurrence of dangerous situations such as short circuit and combustion inside the capacitor, thereby improving the safety of the capacitor.

[0032] The inner side surface of the insulating sleeve 18 is provided with an annular concave notch 17 that is butted against the inner ring 8 .

[0033] The butt joint of the annular concave notch 17 and the inner ring 8 provides a clear positioning point for the insulating sleeve 18. This helps to ensure that the insulating sleeve 18 can be accurately placed in the predetermined position during the assembly process, reducing assembly errors. Through the cooperation of the annular concave notch 17 and the inner ring 8, the connection between the insulating sleeve 18 and the sealant cover 6 is more secure. This enhances the structural stability of the entire capacitor, making it less likely to deform or damage when subjected to external forces. The design of the annular concave notch 17 makes the assembly of the insulating sleeve 18 simpler and more direct. During assembly, it is only necessary to align the annular concave notch 17 of the insulating sleeve 18 with the inner ring 8 of the sealant cover 6 and gently press it in. This design reduces the assembly steps and complexity, improves production efficiency, and the close cooperation of the annular concave notch 17 and the inner ring 8 helps to improve the sealing of the capacitor. When the insulating sleeve 18 is tightly connected to the sealant cover 6, the gap between them is minimized, thereby reducing the possibility of external impurities such as moisture and dust entering the interior of the capacitor.

[0034] The positive electrode pin 3 and the negative electrode pin 4 are respectively inserted through the silicone sealing pad 5 and the sealing rubber cover 6.

[0035] The design of the silicone seal 5 and the sealant cover 6 has the function of waterproof and dustproof. The pins run through these seals, so that the overall sealing of the capacitor is strengthened. Even in the case of a harsh external environment, it can effectively prevent moisture and dust from entering the capacitor, protecting its internal circuits and components from damage. The pins run through the silicone seal 5 and the sealant cover 6, increasing the connection area between the pins and the capacitor as a whole, thereby improving the fixation of the pins. This helps prevent the pins from loosening or falling off under vibration or external force, ensuring the long-term stability of the capacitor.

[0036] The bottom of the sealant cover 6 is provided with a protrusion 12 which is integrally formed therewith and is located outside the positive electrode pin 3 and the negative electrode pin 4 .

[0037] The raised portion 12 can provide additional support and fixation to ensure that the positive pin 3 and the negative pin 4 remain stable during the operation of the capacitor and are not easy to loosen or fall off. The raised portion 12 is located on the outside of the pin, which can effectively isolate the pin from the external environment, improve the insulation performance of the pin, and reduce the risk of electrical failure. The raised portion 12 is provided between the pins to ensure that a certain distance is maintained between the pins, thereby preventing short circuits between the pins and ensuring the normal operation of the capacitor. The raised portion 12 is integrally formed with the sealant cover 6, which can enhance the structural strength of the entire sealant cover 6 and improve the overall stability and durability of the capacitor.

[0038] The outer side surface of the sealant cover 6 is provided with a concave annular groove 13 with a V-shaped cross section, and the aluminum shell 11 is provided with an annular concave portion 14 pressed into the concave annular groove 13 .

[0039] The V-shaped concave annular groove 13 and the annular concave portion 14 cooperate to form a sealing structure. When the aluminum shell 11 is squeezed into the concave annular groove 13, the contact area between the two increases, thereby improving the sealing effect and preventing external impurities such as moisture and dust from entering the capacitor. This cooperation between the aluminum shell 11 and the sealant cover 6 can increase the connection strength between the two, making the capacitor more stable when subjected to external forces and less prone to deformation or damage.

[0040] The bottom side of the aluminum shell 11 is provided with two flanged portions 15 which are folded to the bottom of the sealant cover 6 and are symmetrically arranged, and two openings 16 are provided between the two flanged portions 15 .

[0041] The setting of the flange portion 15 can increase the connection area between the aluminum shell 11 and the sealant cover 6, thereby improving the connection strength between the two and making the capacitor more stable. The design of the two openings 16 can provide a channel for air circulation, so that the heat generated by the capacitor during operation can be dissipated in time, thereby maintaining the stable operation of the capacitor.

[0042] The vertical assembly type solid capacitor improves the working stability and safety of the capacitor by designing and optimizing each component of the capacitor. Specifically, the design of the slot 7 improves the installation efficiency; the design of the raised portion 12 can ensure that the pin remains stable during the operation of the capacitor and reduce the risk of electrical failure; the cooperation of the V-shaped concave ring groove 13 and the annular concave portion 14 and the setting of the flange portion 15 can increase the connection strength between the aluminum shell 11 and the sealant cover 6, improve the stability of the capacitor, and prevent the occurrence of dangerous situations such as internal short circuit and combustion; the design of the annular concave notch 17 helps to improve the sealing of the capacitor and reduce the entry of external moisture, dust and other impurities into the capacitor; the design of the silicone sealing pad 5 and the sealant cover 6 has the function of waterproof and dustproof, further enhancing the overall sealing of the capacitor and protecting its internal circuits and components from damage. These optimized designs jointly ensure the long-term stable operation of the capacitor and improve its working safety.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
