[0022] Please see Figures 1-5 This utility model provides a technical solution: a protective structure for cable joint connection, including a main body 10, a base plate 8 and a porcelain bushing 6. The main body 10 is disposed inside the porcelain bushing 6, and the base plate 8 is installed at the lower end of the porcelain bushing 6.

[0023] The main body 10, as the core conductive component of the cable connector, is made of high-purity, high-conductivity copper alloy. Its internal structure is specially designed, and the conductors are connected by a precision crimping process to ensure stable current transmission and extremely low resistance. At the same time, the surface of the main body 10 is treated with anti-oxidation to effectively resist external environmental corrosion and extend its service life. The porcelain bushing 6 is made of high-strength ceramic material, which has excellent insulation performance and mechanical strength. Its internal space is precisely designed according to the size of the main body 10, and its inner wall is smooth and coated with an insulating coating, which can effectively isolate the main body 10 from the external environment and reduce the occurrence of leakage.

[0024] The following section will describe in detail the specific design and function of a protective structure for cable connectors.

[0025] In this implementation scheme: A connector 14 is fixedly connected to the lower side of the porcelain sleeve 6. The connector 14 is integrally formed from a high-strength ceramic material that matches the material of the porcelain sleeve 6. Its structural design is robust and has good insulation performance, ensuring stability and insulation when connected to the base plate 8. The base plate 8 is fixedly connected to the surface of the connector 14 by bolts. A lead rod 2 is sleeved and connected to the upper end of the main body 10. An outdoor line clamp 1 is sleeved and connected to the upper end of the lead rod 2. The connection between the main body 10 and the lead rod 2 is fixed by a lead seal 12. The lead seal 12 is made of high-purity lead alloy material. After heating, it can fill the gap between the main body 10 and the lead rod 2. After cooling, it forms a solid sealing layer, effectively reducing loosening at the connection and providing a certain degree of moisture and oxidation prevention. A first heat sleeve 13 is fitted onto the surface. The first heat sleeve 13 is made of radiation cross-linked polyolefin material, which has good heat shrinkage and insulation properties. After heating, the first heat sleeve 13 will tightly wrap the lead seal 12 part, further enhancing the sealing and insulation effect, reducing the corrosion of the lead seal 12 by the external environment, and at the same time providing mechanical protection for the connection. The outlet rod 2 is fixed to the outdoor clamp 1 by bolts. A top cover 4 is fitted onto the surface of the outlet rod 2. The top cover 4 is made of metal and the surface is treated with anti-rust and anti-corrosion. Its shape matches the upper end of the ceramic sleeve 6, which can tightly cover the connection part of the outlet rod 2 and the main body 10, reducing the entry of rainwater, dust and other external substances, and playing a protective role. An installation head 11 is fixedly connected to the upper side of the ceramic sleeve 6, and the top cover 4 is fixedly connected to the upper end of the installation head 11 by bolts.

[0026] Specifically, a rain cover 3 is fitted onto the surface of the outlet rod 2. A rubber ring is provided at the connection between the rain cover 3 and the outlet rod 2. The rubber ring is made of highly elastic and aging-resistant silicone rubber material with a circular cross-section. During installation, it is squeezed between the rain cover 3 and the outlet rod 2, which can fully fill the gap, enhance the sealing between the rain cover 3 and the outlet rod 2, and reduce rainwater leakage.

[0027] In this embodiment: the rain cover 3 is made of high-strength engineering plastic material, which has good weather resistance and impact resistance. Its shape design conforms to the principle of aerodynamics, which can effectively guide rainwater to flow down and reduce rainwater accumulation.

[0028] Specifically, the rain cover 3 is fitted onto the surface of the mounting head 11, and the surface of the main body 10 is coated with insulating oil 5. The insulating oil 5 is made of high-purity mineral oil or synthetic oil, which has excellent insulation and moisture-proof properties. After being applied to the surface of the main body 10, it can form a uniform insulating protective film, which not only increases the insulation performance of the main body 10, but also reduces the surface moisture and oxidation to a certain extent.

[0029] Specifically, a stress cone 7 is fixedly connected to the surface of the main body 10, and a supporting insulator 9 is fixedly connected to the lower surface of the base plate 8.

[0030] The stress cone 7 is made of high-polymer insulating material. Its shape and size are designed with strict electric field simulation. It can effectively improve the electric field distribution at the cable joint, evenly disperse the electric field intensity, and reduce the partial discharge and insulation aging caused by local electric field concentration, thereby improving the electrical performance and service life of the cable joint. The support insulator 9 is made of ceramic or composite insulating material. It has good insulation performance and mechanical strength. It can insulate the base plate 8 from the ground or other supporting structures, and at the same time provide stable support for the entire protective structure, ensuring that the cable joint will not be damaged due to uneven stress during operation.

[0031] In this embodiment: further, a connecting sleeve 15 is sleeved on the surface of the main body 10, the connecting sleeve 15 is fixedly connected to the main body 10 through a lead seal 12, and a rubber sleeve 16 is sleeved between the connecting sleeve 15 and the main body 10, the rubber sleeve 16 is snapped into the inside of the base plate 8.

[0032] Specifically, a support sleeve 17 is fixedly connected to the lower surface of the base plate 8 by bolts, and the support sleeve 17 is fixed to the surface of the main body 10 by lead seal 12.

[0033] Specifically, a second heat sleeve 18 is fitted and connected at the connection between the support sleeve 17 and the lead seal 12 of the main body 10.

[0034] Working Principle: During overall installation, the main body 10 is placed inside the porcelain bushing 6. The base plate 8 is fixed to the connector 14 at the lower end of the porcelain bushing 6 with bolts, thus supporting and fixing the main body 10. The cable outlet rod 2 is fitted onto the upper end of the main body 10, and the outdoor cable clamp 1 is fitted onto the upper end of the cable outlet rod 2 and fixed with bolts for connecting external cables. The top cover 4 is fixed to the mounting head 11 at the upper end of the porcelain bushing 6 with bolts, protecting the connection between the cable outlet rod 2 and the main body 10. A lead seal 12 is used to fix the connection between the main body 10 and the cable outlet rod 2, and a first heat sleeve 13 is fitted. The lead seal 12 prevents the connection from loosening, and the first heat sleeve 13 provides sealing and insulation. A rain cover 3 is fitted onto the surface of the cable outlet rod 2. A rubber ring is set at the connection between the rain cover 3 and the cable outlet rod 2, which enhances the sealing between the rain cover 3 and the cable outlet rod 2. The rain cover 3 covers the cable outlet rod. The connection point between the cable outlet pole 2 and the outdoor clamp 1 reduces the ingress of rainwater and external substances. The surface of the main body 10 is coated with insulating oil 5, which increases the insulation performance of the main body 10. Stress cones 7 are fixedly connected to the surface of the main body 10. Stress cones 7 are used to improve the electric field distribution at the cable joint and improve the electrical performance of the cable joint. The rain cover 3 in the equipment, together with the rubber ring, covers the connection point between the cable outlet pole 2 and the outdoor clamp 1 to prevent rainwater and dust from entering. The porcelain bushing 6 protects the connection end of the main body 10 and isolates the connection of the main body 10 from the influence of the external environment. At the same time, the insulating oil 5 not only improves the insulation performance, but also forms a moisture-proof and anti-corrosion coating on the surface of the main body 10. The setting of stress cones 7 specifically improves the electric field distribution at the cable joint and reduces the situation of partial discharge and insulation aging caused by electric field concentration. Compared with the existing technology, this device improves the protection performance of the equipment and increases the service life of the equipment.

[0035] During the sealing installation at the connection between the equipment and the base plate 8, the connecting sleeve 15 is fitted onto the surface of the main body 10. The connecting sleeve 15 is fixed to the main body 10 by a lead seal 12. A rubber sleeve 16 is fitted between the connecting sleeve 15 and the main body 10, and the rubber sleeve 16 is snapped into the interior of the base plate 8. The rubber sleeve 16 further enhances the sealing between the main body 10 and the base plate 8, reducing the entry of external substances into the interior of the main body 10. A support sleeve 17 is fixed to the lower surface of the base plate 8 by bolts. The support sleeve 17 is fixed to the main body 10 by a lead seal 12. The support sleeve 17 provides support to the main body 10, making the cable joint more secure. The device is stable, and a second heat sleeve 18 is fitted at the connection between the support sleeve 17 and the lead seal 12 of the main body 10. The second heat sleeve 18 protects the lead seal 12 and reduces the damage caused by external factors, ensuring the sealing and connection performance of the cable joint. By setting the porcelain sleeve 6, the base plate 8 and the support sleeve 17, a stable mechanical frame can be formed. The double fixing method of bolts and lead seal 12 reduces the damage caused by displacement due to vibration and collision during transportation, installation and operation. Compared with the existing equipment, this equipment has enhanced support and improved the stability of the equipment.
