[0008] According to the aforementioned cable connector protection assembly for power engineering, four sliding grooves are symmetrically arranged on the front and rear sides of the protective shell. The four symmetrically distributed sliding grooves provide diverse installation positions, facilitating adaptation to different cable connectors and enhancing the flexibility of the assembly.

[0009] According to the aforementioned cable joint protection assembly for power engineering, an auxiliary component is provided on the outer surface of the protective shell. This auxiliary component includes a fixing block, connecting bolts, connecting nuts, extension blocks, embedding grooves, and contact washers. Extension blocks are fixedly connected to both the front and rear sides of the protective shell.

Several fixing blocks are fixedly connected to both the left and right sides of the protective shell, and each fixing block is fixedly connected to a connecting nut via connecting bolts. The auxiliary component enables the splicing of the protective shell, enhances protection, and provides cushioning and sealing through the contact washers, thereby improving the overall protective performance.

[0010] According to the aforementioned cable joint protection assembly for power engineering, the number of extension blocks and the number of protective shells are correspondingly arranged, and the contact washers and fixing rings are arranged in parallel. The corresponding arrangement of extension blocks ensures structural integrity, while the parallel arrangement of contact washers and fixing rings provides multi-directional cable protection, enhancing the protection effect.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] This utility model is equipped with a sliding groove, a sliding rod, a positioning bolt, a fixing ring, a fixing bolt, and an adjusting nut. The fixing ring, which is fixedly connected to the side wall of the moving rod, works in conjunction with the fixing bolt and adjusting nut above it to form a stable relationship with the cable. This ensures that the cable always remains stable and avoids problems such as poor contact and wear at the joint caused by cable shaking, thereby improving the stability and reliability of the entire cable joint protection assembly.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model discloses a cable joint protection component for power engineering, comprising: a protective shell 1 and auxiliary components. Each of the outer surfaces of the two protective shells 1 has a sliding groove 4, which provides a sliding track for a sliding rod 5, allowing the sliding rod 5 to be adjusted in position along the outer surface of the protective shell 1, laying the foundation for subsequent positioning and fixing operations. The sliding rod 5 is slidably connected to the inner surface of the sliding groove 4, allowing the sliding rod 5 to move flexibly within the sliding groove 4, facilitating position adjustment according to actual needs to adapt to the protection requirements of cable joints of different specifications. Two positioning bolts 6 are threadedly connected to the upper surface of the sliding rod 5. When tightened, the positioning bolts 6 abut against the inner surface of the sliding groove 4, thereby fixing the sliding rod 5 in place. The specific position of the groove 4 ensures that the sliding rod 5 will not slide arbitrarily during use. A fixing ring 7 is fixedly connected to the side wall of the sliding rod 5. The fixing ring 7 is connected to the protective shell 1 through the sliding rod 5, providing a key component for fixing the cable, so that the cable can be stably constrained within the protective assembly. A fixing bolt 11 is provided on the upper surface of the fixing ring 7. The fixing bolt 11 is used to pass through the fixing ring 7 and cooperate with the adjusting nut 12 to tighten the cable, ensuring that the cable is stably fixed within the fixing ring 7. The adjusting nut 12 is threadedly connected to the outer surface of the fixing bolt 11. The adjusting nut 12 can adjust the degree of compression on the fixing ring 7 by cooperating with the thread of the fixing bolt 11, thereby adapting to the fixing requirements of cables of different thicknesses.

[0023] Two symmetrically arranged fixing rings 7 can simultaneously constrain the cable from both sides, ensuring uniform force on the cable and improving the stability and reliability of the cable fixation. The upper surface of the adjusting nut 12 abuts against the fixing ring 7, thereby tightening the fixing ring 7 and firmly fixing the cable inside the fixing ring 7. The positioning bolt 6 abuts against the inner surface of the sliding groove 4, restricting the sliding rod 5 within the sliding groove 4 and keeping the sliding rod 5 and its connected fixing ring 7 in a fixed position. The fixing bolts 11 are symmetrically arranged on the left and right sides of the fixing ring 7. The symmetrical distribution of the fixing bolts 11 ensures that the tightening force of the fixing ring 7 on the cable is evenly distributed, preventing the cable from being subjected to uneven force. To prevent damage from uneven installation, the number of adjusting nuts 12 and fixing bolts 11 are correspondingly set to ensure that each fixing bolt 11 can be tightened and adjusted through the corresponding adjusting nut 12, ensuring the effectiveness and consistency of the fixing operation. Sliding grooves 4 are symmetrically arranged on the front and rear sides of the protective shell 1. The symmetrical distribution of sliding grooves 4 on the front and rear sides of the protective shell 1 makes the installation and force distribution of the sliding rod 5 and fixing ring 7 more balanced, enhancing the overall stability of the protective assembly. There are four sliding grooves 4, providing more installation and adjustment position options for the sliding rod 5, allowing for more flexible adaptation to the installation requirements of different cable connectors. The outer surface of the protective shell 1 is provided with auxiliary components, which enhance the functionality and practicality of the protective shell 1, facilitating its installation and connection. The protective housing 1 provides support for further protection of the cable joint. The auxiliary components include a fixing block 2, connecting bolts 3, connecting nuts 13, extension blocks 8, embedding grooves 9, and contact washers 10. These components work together to achieve multiple functions such as splicing and fixing of the protective housing 1 and enhancing cable protection, ensuring the normal operation of the cable joint protection assembly for power engineering. Extension blocks 8 are fixedly connected to both the front and rear sides of the protective housing 1. The extension blocks 8 increase the connection area of ​​the protective housing 1, facilitating connection with other components, and also provide a carrier for the embedding grooves 9 and contact washers 10. Two embedding grooves 9 are formed on the inner surface of the extension blocks 8. The embedding grooves 9 can be used to embed other components or fillers, further enhancing the protection of the cable joint, and providing installation space for the contact washers 10. The inner surface of the embedded groove 9 is provided with a contact washer 10. The contact washer 10 contacts the cable, serving as a buffer and seal to prevent direct friction between the cable and the embedded groove 9. It also enhances the sealing performance of the protective assembly, preventing external factors from damaging the cable connector. Several fixing blocks 2 are fixedly connected to both sides of the protective shell 1. The fixing blocks 2 provide fixing points for the connection between the protective shells 1. Multiple protective shells 1 can be connected together by connecting bolts 3 and connecting nuts 13 to form a complete cable connector protection structure. Each fixing block 2 is fixedly connected to a connecting nut 13 by a connecting bolt 3. The connecting bolt 3 and connecting nut 13 cooperate to tightly connect the fixing blocks 2, achieving a stable splicing between the protective shells 1 and ensuring the overall structural strength of the protective assembly.The number of extension blocks 8 corresponds to the number of protective shells 1, ensuring that each protective shell 1 can be effectively connected and reinforced with protection through the extension blocks 8. This ensures the uniformity and integrity of the protection components. The contact washers 10 and retaining rings 7 are arranged in parallel, allowing them to simultaneously protect and secure the cable at different locations, ensuring the stability and safety of the cable within the protection components from multiple directions.

[0024] Working principle: First, the protective shell 1 is assembled. The fixing blocks 2 on the left and right sides of multiple protective shells 1 are aligned. Connecting bolts 3 are passed through the fixing blocks 2 and threaded onto connecting nuts 13. The connecting nuts 13 are tightened to achieve a stable connection between the protective shells 1, forming a complete protective structure. Next, the sliding rod 5 and fixing ring 7 assembly is installed. The sliding rod 5 is slid along the sliding groove 4 on the outer surface of the protective shell 1. Adjusting the sliding rod 5 to a suitable position according to the position and specifications of the cable connector, the positioning bolts 6 on the upper surface of the sliding rod 5 are tightened to make it contact the inner surface of the sliding groove 4, fixing the position of the sliding rod 5. Since the sliding grooves 4 are symmetrically arranged on the front and rear sides of the protective shell 1 and there are four of them, the installation position can be flexibly selected. Then, the fixing bolts on the upper surface of the fixing ring 7 are used to... With the cooperation of adjusting nut 11 and adjusting nut 12, fixing ring 7 is initially installed on the side wall of sliding rod 5. Then, the cable is fixed by placing the cable between two symmetrically arranged fixing rings 7. By rotating adjusting nut 12, it engages with fixing bolt 11 threadedly, adjusting the tightness of the fixing ring 7, thereby firmly fixing the cable in the fixing ring 7. Fixing bolt 11 is symmetrically arranged on the left and right sides of fixing ring 7 to ensure uniform distribution of cable fastening force. Finally, abutment washers 10 are placed in the embedded grooves 9 on the inner surface of extension blocks 8 on the front and rear sides of protective shell 1. The abutment washers 10 contact the cable, playing a buffering and sealing role, further enhancing the protection of the cable joint and preventing external factors from damaging the cable joint. At the same time, the extension blocks 8 increase the connection area and also provide an installation carrier for the abutment washers 10.
