[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] The purpose of this invention is to provide an inflatable connector with a filter for packaging GIS equipment and a method of using it, so as to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively prevents foreign objects such as metal powder from being blown into the equipment during the inflation operation, effectively improves the reliability of the equipment, effectively reduces the risk of discharge caused by foreign objects, improves product quality, and reduces the cost of on-site repair and replacement of equipment.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1 This embodiment provides a filter-equipped inflation connector 100 for GIS equipment packaging, as shown in Figures 1-5. It includes a self-sealing inflation connector 1 and a filter assembly 2. The self-sealing inflation connector 1 is used for a detachable sealed connection with the packaging cavity 3 of the GIS equipment. The self-sealing inflation connector 1 has an inlet end, an outlet end, and a self-sealing inflation channel connecting the inlet end and the outlet end. The inlet end extends out of the packaging cavity 3, and the outlet end communicates with the interior of the packaging cavity 3. The filter assembly 2 is located at the outlet end and inside the packaging cavity 3, used to filter the gas entering the packaging cavity 3. The self-sealing inflation connector 1 achieves a detachable sealed connection with the GIS equipment packaging cavity 3, facilitating installation and disassembly when packaging different GIS equipment, thus improving the versatility of the inflation connector. The self-sealing inflation channel ensures that gas can flow smoothly from the inlet end to the outlet end into the packaging cavity 3. The filter assembly 2 is located at the air outlet and inside the packaging cavity 3. It can directly filter the gas that is about to enter the packaging cavity 3 of the GIS equipment, effectively blocking foreign objects and preventing them from entering the GIS equipment, thus improving the reliability of the equipment.

[0021] In a preferred embodiment, the filter assembly 2 includes a mounting block 21, a first locking member, a dust-free filter cloth 22, and a second locking member. The mounting block 21 has a gas channel 212 communicating with the outlet end. One end of the mounting block 21 near the self-sealing inflation connector 1 has a connecting portion adapted to the outer circumferential surface of the outlet end. The connecting portion is fixedly connected to the outlet end by the first locking member. The other end of the mounting block 21 has a mounting groove 211 communicating with the gas channel 212. The dust-free filter cloth 22 is installed in the mounting groove 211 by the second locking member, and the dust-free filter cloth 22 covers the port of the gas channel 212. The gas channel 212 of the mounting block 21 communicates with the outlet end of the self-sealing inflation connector 1, ensuring smooth gas flow. The connecting portion is fixed to the outlet end by the first locking member, ensuring a stable connection between the filter assembly 2 and the self-sealing inflation connector 1. The mounting slot 211 facilitates the installation of the dust-free filter cloth 22. The second locking component fixes the dust-free filter cloth 22 to the mounting slot 211 and covers the port of the gas channel 212, so that the gas must be filtered through the dust-free filter cloth 22 before entering the packaging cavity 3, thereby enhancing the filtration effect and further protecting the GIS equipment from foreign objects.

[0022] In a preferred embodiment, the second locking member includes a pressure plate 23 and a plurality of locking screws 24. The end face of the mounting block 21 away from the self-sealing inflation connector 1 is provided with a plurality of mounting screw holes 214. The pressure plate 23 is provided with a plurality of mounting through holes 231 in its circumference. Each mounting through hole 231 corresponds one-to-one with the corresponding mounting screw hole 214. The locking screws 24 pass through the mounting through holes 231 and are threadedly connected to the mounting screw holes 214 to press and fix the dust-free filter cloth 22 in the mounting groove 211. The pressure plate 23 is provided with a vent hole 232. Through the combination of the pressure plate 23 and the locking screws 24, the dust-free filter cloth 22 can be pressed evenly in the mounting groove 211, ensuring that the dust-free filter cloth 22 is firmly installed and avoiding displacement under gas impact, which would affect the filtration effect. The vent 232 on the pressure plate 23 not only ensures that the gas can pass through the pressure plate 23 smoothly, but also further fixes the dust-free filter cloth 22, ensuring that the gas always enters the packaging cavity 3 after being filtered by the dust-free filter cloth 22.

[0023] In a preferred embodiment, the thickness of the dust-free filter cloth 22 is adapted to the depth of the mounting groove 211, so that after the pressure plate 23 presses the dust-free filter cloth 22, the surface of the dust-free filter cloth 22 is flush with the end face of the mounting block 21 away from the self-sealing air inlet 1, ensuring the compactness and aesthetics of the overall structure, while avoiding the impact on the uniformity and stability of gas filtration due to the protrusion or depression of the dust-free filter cloth 22, so that the gas can pass through the dust-free filter cloth 22 more evenly for filtration, thereby improving the filtration quality.

[0024] In a preferred embodiment, the inner wall of the mounting screw hole 214 is coated with an anaerobic adhesive layer 215. The anaerobic adhesive layer 215 can enhance the connection strength between the locking screw 24 and the mounting screw hole 214, prevent the locking screw 24 from loosening due to gas pressure fluctuations during the inflation process, and ensure that the pressure plate 23 always firmly presses the dust-free filter cloth 22, maintaining the stability and reliability of the filter assembly 2.

[0025] In a preferred embodiment, the self-sealing inflation connector 1 includes a nozzle body 11, a valve core 12, and a threaded section 13. The nozzle body 11 and the threaded section 13 are integrally connected. The valve core 12 is installed within the nozzle body 11 and the threaded section 13 to form a self-sealing inflation channel. The first locking element is a locking nut 25, and the connecting part of the mounting block 21 is a snap-fit ​​ring 213. The threaded section 13 of the self-sealing inflation connector 1 passes through the mounting groove 211, the snap-fit ​​ring 213, and the wall of the packaging cavity 3, and is threadedly connected to the locking nut 25 to press and fix the mounting block 21 to the inner wall of the packaging cavity 3. The integral connection of the nozzle body 11, the valve core 12, and the threaded section 13 enhances the structural strength of the self-sealing inflation connector 1. The valve core 12 forms a self-sealing inflation channel, which can effectively control the gas inflow and outflow. By engaging the threaded section 13 with the locking nut 25, the mounting block 21 is securely fixed to the inner wall of the packaging cavity 3, ensuring a tight connection between the filter assembly 2, the self-sealing inflation connector 1, and the packaging cavity 3, preventing gas leakage and guaranteeing the sealing and stability of the inflation process.

[0026] In a preferred embodiment, the system further includes a sealing seat 14 and a sealing washer 15. The sealing seat 14 is fitted onto the threaded section 13 and located between the inner wall of the packaging cavity 3 and the snap ring 213. The sealing washer 15 is fitted onto the threaded section 13 and located between the locking nut 25 and the outer wall of the packaging cavity 3. The sealing seat 14 and the sealing washer 15 further enhance the sealing performance of the connection between the self-sealing inflation connector 1 and the packaging cavity 3, preventing gas leakage from the connection gap and ensuring that all gas injected into the packaging cavity 3 is filtered by the filter assembly 2 before entering, thereby improving inflation efficiency and filtration effect. At the same time, it also protects the external environment of the packaging cavity 3 from the influence of gas leakage.

[0027] In a preferred embodiment, a nozzle cap 16 is also included. The nozzle cap 16 is threaded to one end of the nozzle body 11 away from the threaded section 13 to seal the air inlet. When not inflating, the nozzle cap 16 seals the air inlet to prevent external dust, impurities and other foreign objects from entering the self-sealing inflation channel from the air inlet, thereby preventing them from entering the packaging cavity 3 and contaminating the GIS equipment. At the same time, it can also protect components such as the valve core 12 from the influence of the external environment and extend the service life of the inflation connector.

[0028] Example 2 This embodiment also provides a GIS equipment packaging, including: a packaging cavity 3 and a filter-equipped inflation connector 100 for GIS equipment packaging as described in any of the embodiments. The packaging cavity 3 is used to accommodate the GIS equipment. The air inlet end of the self-sealing inflation channel extends out of the packaging cavity 3, and the air outlet end of the self-sealing inflation channel is connected to the inside of the packaging cavity 3. The filter assembly 2 is disposed at the air outlet end of the self-sealing inflation connector 1 and located inside the packaging cavity 3. The filter-equipped inflation connector and the packaging cavity 3 are combined to form a complete GIS equipment packaging, so that the GIS equipment is effectively protected from the inflation source during the packaging process, preventing foreign objects from entering the packaging cavity 3 and contacting the GIS equipment during the inflation process. This provides reliable packaging protection for the GIS equipment and ensures the safety and reliability of the equipment during the packaging and storage process.

[0029] Example 3 This embodiment also provides a method of using the air-inflating connector 100 with filter for packaging GIS equipment as described in any of Embodiment 1, including the following steps: S1: Install the filter assembly 2 on the outlet end of the self-sealing inflation connector 1 to ensure that the filter assembly 2 is correctly installed on the self-sealing inflation connector 1 before inflation, so as to prepare for gas filtration during the subsequent inflation process, ensure that the filtration function works normally, and prevent foreign objects from entering the packaging cavity 3.

[0030] S2: Pass the air inlet end of the self-sealing inflation connector 1 through the wall of the packaging cavity 3 of the GIS equipment and seal the self-sealing inflation connector 1 with the packaging cavity 3. The air inlet end of the self-sealing inflation channel is located outside the packaging cavity 3, and the air outlet end is located inside the packaging cavity 3. This achieves a sealed connection between the self-sealing inflation connector 1 and the packaging cavity 3, ensuring that the gas will not leak during inflation. The correct arrangement of the self-sealing inflation channel allows the gas to smoothly enter the packaging cavity 3 from the outside. It also ensures that the filter assembly 2 can effectively filter the gas inside the packaging cavity 3.

[0031] S3: Gas is injected into the packaging cavity 3 through the air inlet of the self-sealing inflation channel. The gas passes through the self-sealing inflation channel and the filter component 2 in sequence. After being filtered by the filter component 2, the gas enters the packaging cavity 3. This clarifies the inflation operation process and ensures that the gas follows the designed path, first passing through the self-sealing inflation channel and then being filtered by the filter component 2 before entering the packaging cavity 3. This effectively prevents foreign objects from entering, ensuring the safety of the GIS equipment during the inflation packaging process and improving the reliability of the equipment.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope.
