[0037] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] Figure 1 This is a structural diagram of an automatic power-off device for power grid operation failure provided by the utility model; Figure 2 This is a schematic diagram of the top view of a device for automatically shutting off power in the event of a power grid failure provided by the present invention; Figure 3 for Figure 2 Magnified view of area A in center.

[0039] Reference below Figure 1-Figure 3 According to an embodiment of the present invention, an automatic power-off device for power grid operation failures includes a housing 100. An input line 120 is provided at one end of the housing 100, and an output line 110 is provided at the other end of the housing 100. Both the input line 120 and the output line 110 are connected to the housing 100 via a connecting coil. The housing 100 defines a mounting slot 130. A mounting compartment 200 is adapted to fit within the mounting slot 130 so that the mounting compartment 200 can be snapped into place within the mounting slot 130. Active power connectors 300 are provided at both ends of the mounting compartment 200. When the mounting compartment 200 is mounted on the active power connectors 300, the active power connectors 300 connect to the connecting coil to form a pathway. A fuse cartridge is adapted to fit within the mounting compartment 200 so that the fuse cartridge can be installed within the mounting compartment 200. When the fuse cartridge is installed within the mounting compartment 200, the active power connector is converted into a fixed interface for stable installation.

[0040] The working principle of the automatic power-off device for power grid operation failure is that by connecting the input line 120 and the output line 110 to the connecting coil inside the housing 100, when the power grid is operating normally, the current forms a path through the connecting coil, the movable power connector 300 and the fuse tube in the installation compartment 200. When an abnormal situation such as overload or short circuit occurs in the power grid, the fuse tube will melt due to the high temperature generated by the overcurrent, thereby automatically cutting off the circuit. The adaptive design of the installation slot 130 and the installation compartment 200 ensures that the fuse tube can be firmly installed inside the housing 100, and the setting of the movable power connector 300 further ensures a reliable connection between the fuse tube and the connecting coil. The movable power connector 300 will be converted into a fixed interface when the fuse tube is installed to avoid poor contact due to mechanical vibration or external force, thereby improving the reliability of the electrical connection.

[0041] Specifically, the automatic power-off device for power grid operation failures effectively solves the problems of unstable fixing, poor contact, and complicated replacement of fuse tubes in traditional fuse tube power-off devices through the structural design of the housing 100, the mounting slot 130, the mounting compartment 200, and the movable power connector 300. The combination of the mounting slot 130 and the mounting compartment 200 allows the fuse tube to remain stable during the operation of the device, avoiding loosening problems caused by external vibrations or improper installation. The movable power connector 300 can form a fixed interface after being installed in place, ensuring a stable connection between the fuse tube and the connecting coil, eliminating the risk of poor circuit contact. At the same time, this design simplifies the replacement operation of the fuse tube, making equipment maintenance easier, and overall improving the safety of power grid operation and the reliability of the equipment.

[0042] It's worth noting that the structure of the mounting compartment 200 can be adjusted to accommodate fuse tubes of varying sizes based on their specifications. The material and shape of the connecting coil can also be optimized based on specific current requirements to improve conductivity. Furthermore, the number and distribution of the mounting slots 130 can be adjusted to meet specific device requirements, ensuring efficient automatic power-off functionality even when multiple fuse tubes are connected in parallel.

[0043] Please continue to participate Figure 1-Figure 3 As shown, in one possible embodiment, the movable power connector 300 includes: a movable hole 310, which is opened at both ends of the installation chamber 200 and is coaxially arranged with the installation chamber 200; a movable member 320, which is movably arranged on the movable hole 310, and the movable member 320 is a structural member made of conductive material, and the movable direction of the movable member 320 is the axial direction; and a resilient member 330, with both ends of the resilient member 330 respectively mounted on the installation chamber 200 and the movable member 320. In this embodiment, the movable member 320 is mounted on both ends of the installation chamber 200 through the movable hole 310 and is capable of moving in the axial direction. The resilient member 330 is arranged between the installation chamber 200 and the movable member 320. When the fuse tube is installed, the movable member 320 overcomes the elastic force of the resilient member 330 under the action of external force and forms an electrical connection with the connecting coil. After the fuse tube is installed in place, the movable member 320 is automatically reset under the action of the resilient member 330 to form a stable electrical path, thereby ensuring the conductivity of the circuit.

[0044] This structure not only improves the stability and safety of the electrical connection, but also the provision of the resilient member 330 allows the movable member 320 to automatically reset, ensuring the connection reliability of the fuse tube. The movable hole 310 is coaxially arranged with the installation compartment 200, effectively guiding the movement of the movable member 320 during installation and avoiding poor contact caused by misalignment. Furthermore, the use of a conductive material for the movable member 320 improves electrical conductivity, thereby creating a pathway between the fuse tube, the connecting coil, the input line 120, and the output line 110.

[0045] It should be noted that the material of movable member 320 can be selected from various conductive metals, such as copper or aluminum, to optimize conductivity and durability based on specific application requirements. Furthermore, the shape and elastic modulus of resilient member 330 can be adjusted to suit different current specifications to ensure that movable member 320 has appropriate movement resistance and resilience during installation and disconnection.

[0046] When the fuse tube is not installed, the movable part 320 can move back and forth, and the distance between the two movable parts 320 can move back and forth. When the fuse tube is installed, the distance between the movable parts 320 is relatively fixed, so that the movable power connector 300 is fixed, making it easier to install the installation compartment 200.

[0047] Please continue to see Figure 3 As shown, according to one embodiment of the present invention, the movable part 320 also includes a limit plate 321, and the number of limit plates 321 is set to two, and the two limit plates 321 are both located in the middle of the movable part 320; the side wall of the installation bin 200 is located between the two limit plates 321; the size of the limit plate 321 is larger than the size of the movable hole 310.

[0048] Specifically, the design of the limiting plates 321 primarily serves to limit the travel distance of the movable member 320. By positioning the limiting plates 321 in the middle of the movable member 320, the two limiting plates 321 are restrained by the side walls of the mounting compartment 200 during axial movement, thereby ensuring the movable member 320's travel distance. The limiting plates 321 are larger than the size of the movable hole 310, ensuring that the movable member 320 does not exceed the predetermined range during movement, thereby ensuring the stability and security of the electrical connection.

[0049] Furthermore, the provision of the stop plate 321 effectively prevents the movable member 320 from shifting or over-moving during movement, ensuring the accuracy of the electrical connection position and thus avoiding malfunctions caused by poor contact. Furthermore, this design stabilizes the motion trajectory of the movable member 320, improving the reliability of the device over long-term operation. The relative position of the stop plate 321 to the sidewall of the mounting compartment 200 also simplifies installation and maintenance, helping to improve operational efficiency.

[0050] Please continue to see Figure 3 As shown, according to another embodiment of the present invention, both ends of the resilient member 330 are fixedly mounted on the limiting plate 321 and the installation chamber 200 , respectively, and the resilient member 330 is located outside the installation chamber 200 .

[0051] Specifically, the two ends of the resilient member 330 are fixed to the limiting plate 321 and the mounting chamber 200, respectively, providing a stable elastic support. The resilient member 330 is located outside the mounting chamber 200. This arrangement prevents direct contact between the resilient member 330 and the internal fuse tube, preventing it from interfering with its installation, while also effectively ensuring the axial movement of the movable member 320. When an external force pushes on the movable member 320, the resilient member 330 is compressed. Once the external force is removed, it quickly returns to its original position, pushing the movable member 320 back to its original position, thus establishing a stable electrical connection.

[0052] The above structure secures the resilient member 330 to the retaining plate 321 and the mounting compartment 200, and arranges it outside the mounting compartment 200. This prevents the risk of the resilient member 330 directly contacting circuit components, thereby improving the safety of the device. The position and securing method of the resilient member 330 ensure a more stable return process for the movable member 320, thereby ensuring a reliable electrical connection. Furthermore, this external design of the resilient member 330 reduces the complexity of the internal structure, facilitating device installation and maintenance.

[0053] It is worth noting that the resilient element 330 can be made of various elastic elements, such as compression springs and torsion springs, to accommodate varying restoring force requirements. The size, elastic modulus, and material of the resilient element 330 can also be adjusted to provide appropriate restoring force and extend service life, depending on the current specifications and device structure. To further enhance stability, a support structure can be added to the fixed end of the resilient element 330 to ensure reliable installation and operation of the resilient element 330.

[0054] Please continue to see Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, a notch 210 is provided in the middle of the installation compartment 200 for facilitating replacement of the fuse tube.

[0055] Specifically, a notch 210 is provided in the middle of the installation chamber 200, making it easier to remove and insert the fuse tube when replacing it. The design of the notch 210 means that the installation and removal of the fuse tube no longer requires the complete disassembly of the entire installation chamber 200 structure. The replacement work can be completed by simply operating through the notch 210. This notch notch notch 210 simplifies the replacement process and reduces installation errors caused by improper human operation. The notch 210 design in the middle of the installation chamber 200 significantly improves the convenience of replacing the fuse tube and shortens the replacement time. Through the notch 210, technicians can quickly and accurately install and replace the fuse tube, reducing the disassembly and assembly work during maintenance and reducing equipment downtime. In addition, the notch 210 design can also reduce the operator's accidental touching of other components, further improving the safety and accuracy of the operation.

[0056] It should be noted that the size and shape of the notch 210 can be optimized and adjusted based on the specifications of the fuse tube to accommodate the installation requirements of different fuse tube models. Protective structures, such as anti-slip pads or edge guards, can be added to the edges of the notch 210 to further enhance operational safety and convenience. Furthermore, the location of the notch 210 can be adjusted based on the overall equipment layout to maximize the operating space for fuse tube replacement.

[0057] Please continue to see Figure 1 and Figure 2 As shown, according to an optional embodiment of the present invention, it also includes an installation component 400, and the number of the installation components 400 is set to two. The two installation components 400 are respectively fixedly connected to the movable parts 320 located at both ends of the installation compartment 200. The two installation components 400 are both located inside the installation compartment 200. The shape of the installation component 400 is adapted to the fuse tube so that the fuse tube can be stably installed inside the installation compartment 200.

[0058] Specifically, this embodiment provides mounting assemblies 400 at both ends of the mounting chamber 200, so that the fuse tube can be more stably fixed in the mounting chamber 200. Each mounting assembly 400 is fixedly connected to the movable part 320, thereby providing support and guidance during the installation and fixing of the fuse tube. The shape of the mounting assembly 400 is adapted to the outer shape of the fuse tube, so that the fuse tube can be accurately positioned and stably fixed, avoiding the problem of loosening caused by vibration or mechanical stress. The fixing stability of the fuse tube is further improved, and poor contact caused by external force or long-term operation is prevented. The fixed connection design of the mounting assembly 400 and the movable part 320 can provide precise guidance during the installation and fixing of the fuse tube, reduce installation errors, and improve operational efficiency. In addition, the mounting assembly 400 is located inside the mounting chamber 200, which can effectively protect the fuse tube and extend the service life of the equipment.

[0059] It is worth noting that the shape of mounting assembly 400 can be optimized based on the specific shape of the fuse tube to accommodate fuse tubes of varying sizes and types. Mounting assembly 400 can be constructed from materials with excellent wear resistance and insulation properties, such as engineering plastics or ceramics, to enhance safety and service life. To enhance the securement of the fuse tube, auxiliary clips or guide grooves can be added to mounting assembly 400 to further reduce the impact of equipment vibration on the stability of the fuse tube's securement.

[0060] According to a further embodiment of the present invention, the installation assembly 400 includes an insulating part and a connecting part, the connecting part is fixedly connected to the movable part 320, and the connecting part is a structural part made of conductive material. The insulating part is fixedly connected to the connecting part, and the insulating part is a structural part made of insulating material.

[0061] Specifically, the installation assembly 400 is composed of an insulating part and a connecting part. The connecting part is made of a conductive material and is fixedly connected to the movable part 320 so that electrical conduction can be achieved when the fuse tube is installed. The insulating part is fixedly connected to the connecting part to isolate the direct contact between the connecting part and the installation compartment 200 or other metal parts, thereby avoiding short circuits or current leakage. The provision of the insulating part ensures the safety of the electrical connection, while increasing the stability of the fuse tube installation while ensuring electrical conduction. By integrating the insulating part and the connecting part, the contradiction between the safety of the electrical connection and the structural stability is effectively resolved. The use of the insulating part avoids contact between components outside the electrical conduction path and improves the safety of the entire device. At the same time, the conductive connecting part is directly connected to the movable part 320, ensuring that the fuse tube can be quickly and reliably electrically connected when replaced. This design simplifies the structure of the component, reduces the risk of failure during installation, and enhances the durability of the equipment.

[0062] It's worth noting that the insulation component can be made of high-strength, high-temperature-resistant engineering plastics or ceramics to meet the requirements of electrical insulation and mechanical stability. The connector can be made of highly conductive materials such as copper and aluminum, depending on the current requirements, to further optimize the conductivity. Furthermore, the insulation and connector can be secured using a variety of methods, including screws and snaps, to allow for flexible adjustments during replacement or maintenance.

[0063] Please continue to see Figure 1-Figure 3 As shown, in an optional embodiment of the present invention, the resilient member 330 is a resilient spring, with its ends fixedly connected to the sidewalls of the mounting compartment 200 and the retaining plate 321, respectively. When the movable member 320 is pushed by an external force, the resilient spring is compressed and stores elastic potential energy. Once the external force is released, the resilient spring quickly returns to its original position, pushing the movable member 320 back to its initial position. The fixed design of the resilient spring ensures that it consistently provides a stable and appropriate resilient force during the movement of the movable member 320, thereby ensuring the stability and security of the electrical connection.

[0064] Specifically, the use of a rebound spring as the rebound element 330 provides a stable and sufficient restoring force, ensuring reliable movement of the movable element 320 during installation and disconnection of the fuse tube. This spring's mounting method further improves the reset accuracy of the movable element 320, avoiding poor contact caused by poor reset. Furthermore, the rebound spring exhibits excellent fatigue resistance and durability, maintaining a stable rebound force even during extended use, thereby enhancing the overall reliability and service life of the device.

[0065] It should be noted that the rebound spring can be made of stainless steel or alloy spring steel, which exhibits excellent fatigue and corrosion resistance, to enhance its durability. Depending on the size and intended use of the equipment, the rebound spring can be shaped cylindrically, conically, or in other suitable configurations to adjust its elastic modulus. Furthermore, a double-layer spring structure can be employed to enhance the rebound effect and further improve the stability of the equipment, depending on the specific reset requirements.

[0066] Please continue to see Figure 1 and Figure 2 As shown, in some examples of the present invention, in one possible embodiment, the number of mounting grooves 130 is set to be several, and the mounting grooves 130 are evenly distributed, and the number of mounting compartments 200 is set to be several, and the mounting compartments 200 correspond to the mounting grooves 130 one by one.

[0067] Specifically, in this embodiment, the housing 100 is provided with a plurality of mounting slots 130, which are evenly distributed to accommodate multiple mounting compartments 200. Each mounting compartment 200 can be independently inserted into a corresponding mounting slot 130, thereby achieving a multi-path parallel configuration of fuse tubes. In a power grid, when a fault occurs in one path, the corresponding fuse tube can melt and cut off the current in that path, while other paths can continue to operate normally, thereby improving the safety and stability of the power grid. Typically, the number of mounting slots 130 and the number of mounting compartments 200 are both three.

[0068] In the above solution, the number and layout of mounting slots 130 can be adjusted according to actual needs to accommodate equipment with varying current specifications and fuse tube quantities. The shape and depth of mounting slots 130 can also be optimized to ensure secure positioning of mounting bin 200. Furthermore, positioning structures, such as protrusions or guide grooves, can be incorporated into each mounting slot 130 to further enhance the positioning accuracy and stability of mounting bin 200.
