[0007] Furthermore, the internal dimensions of the contact cap body are adapted to the external dimensions of the molten tube body, and the molten tube body and the contact cap body are embedded in each other.

[0008] Furthermore, there are two contact cap bodies, and the two contact cap bodies are symmetrically arranged at both ends of the outer side of the melt tube body with respect to the central axis of the side of the melt tube body.

[0009] Furthermore, the internal dimensions of the end cap body are adapted to the external dimensions of the contact cap body, and the inner surface of the end cap body is in close contact with the outer surface of the contact cap body.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] like Figures 1 to 3 As shown, a novel photovoltaic application fuse includes a fuse tube body 1, a quartz tube body 2, and a limiting and retaining groove 5. The quartz tube body 2 is housed inside the fuse tube body 1, and quartz sand 3 is disposed inside the quartz sand 3. A fusible element 4 is connected inside the quartz sand 3. The internal dimensions of the fuse tube body 1 are adapted to the external dimensions of the quartz tube body 2. The quartz tube body 2 and the fuse tube body 1 are fixedly connected by an adhesive. The adhesive limits the installation of the quartz tube body 2 inside the fuse tube body 1. The quartz tube body 2 allows the fuse to be fixed within the fuse tube body 1. During use, it has a certain degree of high temperature resistance, and the quartz tube has good electrical insulation properties, which can ensure the stable operation of the fuse in a high-voltage environment. Quartz sand 3 is used to support the fuse 4. When the fuse 4 melts during use, the quartz sand 3 will transfer the heat to the fuse tube body 1, ensuring the safe and reliable fuse connection. In addition, the quartz sand 3 can also reduce the friction of the fuse 4, extend the service life of the fuse, reduce the probability of circuit burnout, and further improve the overall practicality and efficiency of the fuse.

An end cap body 7 is provided outside the contact cap body 6, and a protective gasket 8 is added to the upper part of the end cap body 7. The internal dimensions of the contact cap body 6 are adapted to the external dimensions of the fuse tube body 1, and the fuse tube body 1 and the contact cap body 6 are embeddedly connected. There are two contact cap bodies 6, symmetrically arranged at both outer ends of the fuse tube body 1 about the side center axis. The internal dimensions of the end cap body 7 are adapted to the external dimensions of the contact cap body 6, and the inner surface of the end cap body 7 is tightly fitted to the outer surface of the contact cap body 6. The fuse tube body 1 and the end cap body 7 are embeddedly connected, and the end cap body 7 is connected to the fuse tube body 1 through the limiting slots 5. The protective gasket... The protective gasket 8 is embeddedly connected to the end cap body 7, and the outer surface of the protective gasket 8 is tightly fitted to the outer surface of the contact cap body 6. The contact cap body 6 is installed on both ends of the fuse tube body 1 by welding. The contact cap body 6 protects the circuit inside the fuse. At the same time, the end cap body 7 is snapped onto the outside of the contact cap body 6 by the limiting slots 5 opened at both ends of the fuse tube body 1. The limiting slots 5 make the fuse tube body 1 and the end cap body 7 stably matched, so that it can withstand greater energy. At the same time, a protective gasket 8 is added to the upper part of the end cap body 7. The protective gasket 8 improves the overall sealing of the fuse body and prevents the leakage of media such as water, gas, and liquid, ensuring the normal operation of the equipment. This ensures the stable operation and long-term reliability of the photovoltaic application fuse body, and improves the overall practicality and efficiency of the fuse body.

[0022] In summary, this novel photovoltaic application fuse, during use, firstly, utilizes the quartz tube body 2 to provide the fuse with a certain degree of high-temperature resistance. Simultaneously, the quartz tube possesses excellent electrical insulation properties, ensuring stable operation of the fuse under high-voltage environments. Quartz sand 3 supports the fuse element 4; when the fuse element 4 melts during use, the quartz sand 3 transfers heat to the fuse tube body 1, ensuring a safe and reliable fuse connection. Furthermore, the quartz sand 3 reduces friction in the fuse element 4, extending the fuse's lifespan and reducing the probability of circuit burnout. Next, the contact cap body 6 protects the internal circuitry of the fuse.
