With the continuous development of electrified railways, the requirements for contact networks are increasingly high. Traditional contact network design usually uses droppers to connect the contact wire with the load-bearing cable to achieve straightening and stabilization of the contact wire. However, existing droppers mostly adopt flexible structures, and need to be fixed by fasteners during installation, which not only leads to a complicated and inefficient installation process, but also due to the inherent defects of flexible structures, the contact network is easily affected by external factors during operation, resulting in poor stability and affecting the normal operation and maintenance efficiency of the contact network.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0022] In order to solve the technical problems in the background art, such as Figs. 1-2 As shown, this application provides a technical solution: a special component for electrified contact networks, characterized as follows:

[0023] One end of the first body 1 is provided with an annular structure 2, the inner diameter of which matches the outer diameter of the catenary cable to accommodate its passage. The other end is a hollow sleeve 3, with a through hole 4 on its side wall, perpendicular to the axial direction of the sleeve 3. One end of the second body 5 is a rod 6, which fits into the sleeve 3 and can be inserted into it. Limiting holes 7 are provided axially along the rod 6, evenly distributed to provide multiple fixing positions for easy adjustment of the second body 5's installation position within the sleeve 3. The second body 5 is fixed by inserting a high-strength screw into the mating position of the limiting hole 7 and the through hole 4 to ensure a strong and durable connection. The other end of the second body 5 is provided with a fixing member 8, which is connected to the slotted wire. The fixing member 8 can be annular or a snap-fit ​​structure, used to securely connect the second body 5 to the slotted wire. The fixing component 8 has an internal protrusion 9 adapted to the slotted wire. The shape of the protrusion 9 matches the shape of the groove on the side wall of the slotted wire, ensuring that the protrusion 9 can be tightly embedded in the groove on the side wall of the slotted wire, improving the stability and reliability of the connection. During installation, first, the load-bearing cable is passed through the annular structure 2 at one end of the first body 1. Then, the rod 6 of the second body 5 is inserted into the sleeve 3 of the first body 1. The position of the second body 5 in the sleeve 3 is adjusted as needed to align the limiting hole 7 with the through hole 4, and the screw structure is inserted for fixation. Next, the fixing component 8 is connected to the slotted wire, and the protrusion 9 is embedded in the groove on the side wall of the slotted wire, completing the installation.

[0024] In use, the catenary cable bears the tension from the contact wire through the annular structure 2 of the first body 1. The first body 1 and the second body 5 are fixed together by screws to form a stable overall structure, ensuring the stable operation of the contact wire. The tight connection between the fixing component 8 and the slotted conductor ensures smooth current transmission and avoids power loss due to poor contact.

[0025] It should be noted that the inner diameter of the annular structure 2 matches the outer diameter of the catenary cable to ensure that the catenary cable can pass smoothly and be installed securely. This design allows the catenary cable to fit tightly against the inner wall of the annular structure 2 when passing through it, thus achieving a stable installation effect. At the same time, this matching design also helps to reduce the swaying and vibration of the catenary cable during operation, further improving the stability and reliability of the contact network.

[0026] Furthermore, the assembly hole 10 is located in the middle of the first body 1, and the axis of the assembly hole 10 is parallel to the axis of the annular structure 2. The assembly hole 10 allows for precise positioning and fixation of the first body 1 and the load-bearing cable by inserting an auxiliary limiting structure, such as a clip or clamping device, into the assembly hole 10 during installation, thus ensuring the stable installation of the first body 1.

[0027] It should be noted that the slot 11 is provided on the inner wall of the assembly hole 10, and its extension direction is parallel to the axial direction of the assembly hole 10. The slot 11 allows for further fixing and positioning of the assembly during installation, ensuring assembly accuracy and stability. The specific dimensions and shape of the slot 11 can be designed according to actual needs to adapt to different assembly requirements. For example, the slot 11 can be rectangular, T-shaped, or other suitable shapes, and its dimensions should match the auxiliary positioning device used. The slot 11 effectively improves the functionality and flexibility of the assembly hole 10, ensuring the stability and reliability of the first body 1 during installation.

[0028] It should be noted that the reinforcing ribs 12 are disposed on the outer periphery of the mounting holes 10 and protrude from the outer side of the first body 1, symmetrically disposed on both sides of the first body 1. The placement of the reinforcing ribs 12 helps to enhance the structural strength and stability of the first body 1, especially in the area around the mounting holes 10. By placing the reinforcing ribs 12 on the outer periphery of the mounting holes 10, stress concentration around the mounting holes 10 can be effectively dispersed, improving the overall rigidity and deformation resistance of the first body 1. The symmetrical placement of the reinforcing ribs 12 ensures the balance and stability of the first body 1 during installation and use, further improving the reliability and safety of the contact wire system.

[0029] It should be noted that the protrusions 13 are symmetrically arranged on the side wall of the first body 1 and located next to the assembly hole 10. The arrangement of the protrusions 13 helps to enhance the structural strength and stability of the first body 1, especially in the area near the assembly hole 10. A pin hole 14 is provided within the protrusion 13, passing through the assembly hole 10 and perpendicular to its axial direction. This design allows pins to be inserted through the pin holes 14 during installation to further secure and position the assembly, ensuring assembly accuracy and stability. The arrangement of the protrusions 13 and pin holes 14 effectively improves the functionality and flexibility of the assembly hole 10, ensuring the stability and reliability of the first body 1 during installation. The symmetrical arrangement of the protrusions 13 also helps to maintain the balance and stability of the first body 1, further improving the reliability and safety of the contact wire system.

[0030] It is worth noting that the multiple limiting holes 7 are evenly distributed along the axial direction of the rod 6. This design allows for flexible adjustment of the installation position of the second body 5 within the sleeve 3. By aligning different limiting holes 7 with the through holes 4 on the sleeve 3, the second body 5 can be fixed in different positions within the sleeve 3. This adjustability allows the electrified contact network-specific component to adapt to different installation requirements and environmental conditions, improving installation flexibility and convenience. The even distribution of the limiting holes 7 ensures that multiple fixing positions are available along the entire axial direction of the rod 6. For example, if the second body 5 needs to be fixed deeper in the sleeve 3, a limiting hole 7 closer to one end of the rod 6 can be selected; if the second body 5 needs to be fixed shallower in the sleeve 3, a limiting hole 7 closer to the other end of the rod 6 can be selected. This design not only improves installation flexibility but also ensures the stability and reliability of the connection.

[0031] It is worth noting that the fastener 8 adopts a snap-fit ​​structure. The snap-fit ​​structure includes a spring-loaded snap and a corresponding slot. The spring-loaded snap is located at one end of the second body 5, and the slot is provided on the slotted wire. When it is necessary to connect the second body 5 to the slotted wire, align the spring-loaded snap with the slot and press it down firmly, causing the hook of the spring-loaded snap to hook onto the edge of the slot, thus achieving a secure connection. The snap-fit ​​structure design makes the connection process simple and quick, requiring no additional tools or fasteners. At the same time, the elasticity of the snap-fit ​​ensures the reliability of the connection, maintaining stability even under vibration or impact. Furthermore, the snap-fit ​​structure has good reusability; when disassembly or adjustment is required, simply pull the spring-loaded snap to remove it from the slot, facilitating maintenance and replacement.
