[0039] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the embodiments of this disclosure to facilitate a better understanding of the disclosure. However, the technical solutions claimed in this disclosure can be implemented even without these technical details and various variations and modifications based on the following embodiments.

[0040] refer to Figures 1 to 2 The connecting components include: a connecting rod 1 and a rotating nut retainer 2.

[0041] Connecting rod 1 is used to connect two conductors.

[0042] In this embodiment of the disclosure, the connecting rod 1 is connected by overlapping between two conductors.

[0043] The rotating nut retainer 2 includes a bracket 21 and a nut 22. The bracket 21 serves as a support body and is provided with a slot assembly 210 for inserting and positioning the connecting rod. The nut 22 is rotatably mounted on the bracket 21 for fixing the connecting rod 1. The clamping and fixing of the connecting rod 1 can be achieved by rotating the nut 22.

[0044] In this embodiment, the connecting rod 1 can be flexibly made of different materials according to the actual application environment to meet different functional requirements. For example, it can achieve stable conductive connection in high current protection scenarios, or electrical insulation in scenarios requiring isolation. The rotating nut retainer fixes the connecting rod through mechanical locking, which helps to improve the stability and reliability of the connection structure.

[0045] The embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0046] In some embodiments, the connecting rod 1 is used to connect between two conductors for conducting electricity.

[0047] For example, the connecting rod 1 can be made of a conductive metal material, such as copper, aluminum, or their alloys. In scenarios where strong current needs to be guided through the connection of metal protective drain lines, using a connecting rod made of a conductive metal material can achieve a stable connection between the various sections of the metal protective drain line, constructing a robust and reliable conductive structure, which is beneficial to improving the structural stability and protective performance of the metal protective mesh.

[0048] For example, the connecting rod 1 can also be made of an insulating material, such as quartz or ceramic. In scenarios where electrical isolation between two conductors is required, using a connecting rod made of an insulating material can achieve an electrically insulated connection between the conductors, thereby enhancing the safety and applicability of the system.

[0049] refer to Figure 1 In some embodiments, a protrusion structure 12 is provided on the connecting rod 1 near the center and away from the insertion end 11. This protrusion structure 12 can be an annular boss, multiple spaced protrusions, or strip-shaped protrusions extending circumferentially.

[0050] refer to Figure 2 The slot assembly 210 includes a first slot 211, the inner wall of which is provided with a groove that matches the shape of the protrusion structure 12.

[0051] When the connecting rod 1 is inserted into the first slot 211, the protrusion 12 engages with the groove to limit the axial displacement of the connecting rod 1.

[0052] The protruding structure 12 serves as a mechanical limiting structure. After the connecting rod is inserted into the slot, it forms an embedded engagement with the groove on the inner wall of the first slot 211 to prevent axial sliding or detachment.

[0053] The engagement structure between the protrusion 12 and the groove significantly enhances the axial locking capability between the connecting rod and the slot, enabling the connecting components to maintain a stable connection even under strong current impact or vibration.

[0054] refer to Figure 2In some embodiments, the bracket 21 is provided with an annular rotating groove 213, which is located inside or outside the bracket 21. The inner wall of the annular rotating groove 213 is smooth and has a certain depth to accommodate the boss 221 of the nut 22. The axis of the annular rotating groove 213 coincides with the axis of the connecting rod 1.

[0055] refer to Figure 3 The nut 22 is provided with several bosses 221, the shape of which matches the annular rotating groove 213, and is usually an arc or columnar protrusion.

[0056] The nut 22 is rotatably mounted on the bracket 21 by being inserted into the annular rotating groove 213 through the boss 221, so that the nut 22 rotates around the axis of the connecting rod 1 to tighten or loosen the connecting rod 1.

[0057] By setting up a mating structure between the annular rotating groove 213 and the boss 221, a precise rotational connection between the nut 22 and the bracket 21 is achieved. This structure not only improves the stability and maneuverability during the rotation of the nut, but also simplifies the tightening and disassembly of the connecting rod 1, helping to improve on-site construction efficiency. At the same time, since the rotation axis is consistent with the axis of the connecting rod, the uniform distribution of clamping force is ensured, further enhancing the reliability and service life of the connection structure.

[0058] refer to Figure 1 In some embodiments, the insertion end 11 is provided with a threaded section 13, the surface of which is provided with a standard thread to fit the internal thread structure of the nut 22.

[0059] The threaded section 13 has a color-coded marking line 14 on its surface. The length of the marking line 14 from the insertion end 11 corresponds to the preset tightening stroke of the nut 22, and is used to mark the tightening termination position of the nut 22. The marking line 14 is usually a brightly colored marking line or coating for easy visual identification.

[0060] refer to Figure 2 The slot assembly 210 includes a second slot 212, the head of the connecting rod 1 passes through the second slot 212 and extends to the outside of the bracket 21, the nut 22 engages with the threaded section 13, and the nut 22 moves along the threaded section 13 to the marking line 14 when it rotates, thereby achieving mechanical fastening of the connecting rod 1.

[0061] This embodiment of the present disclosure provides a color-coded line 14 on the threaded section 13 of the connecting rod 1, which corresponds to the tightening stroke of the nut 22. This achieves precise calibration of the tightness of the connecting components, which not only improves installation efficiency and operational consistency, but also effectively avoids over-tightening or under-tightening caused by human judgment errors, thereby ensuring the stability and reliability of the connection structure.

[0062] refer to Figure 4This is a schematic diagram of the overall structure of the connecting component after the connecting rod 1 and the rotating nut retainer 2 are installed. The protruding structure 12 of the connecting rod 1 forms an embedded engagement with the groove on the inner wall of the first slot 211. The insertion end 11 and the tail end 16 of the connecting rod 1 are respectively inserted into the second slot 212 and extend to the outside of the bracket 21. The installed connecting component has a Z-shaped structure.

[0063] refer to Figure 5 In some embodiments, the connecting member further includes a support sleeve 3, which is a hollow tube with openings at both ends. The inner diameter of the support sleeve 3 is larger than the outer diameter of the connecting rod 1, so that it can be fitted onto the connecting rod 1.

[0064] The support sleeve 3 is fitted onto the connecting rod 1 and fixed by the nut 22. The support sleeve 3 is used to form a predetermined fixed interval between the conductors at both ends of the connecting rod 1 and to provide support at both ends.

[0065] The length of the support sleeve 3 and the spacing between the conductors 20 at both ends of the connecting rod 1 have a first preset correspondence.

[0066] For example, refer to Figure 5 The support sleeve 3 can be a single integrated structure, fitted onto the connecting rod 1 and the rotating nut retainer 2.

[0067] refer to Figure 6 The support sleeve 3 can also be a segmented structure, which is respectively fitted onto the connecting rods 1 on both sides of the rotating nut retainer 2.

[0068] By introducing the support sleeve 3, precise control and physical support of the spacing between the conductors at both ends of the connecting rod 1 are achieved, which helps to improve the overall rigidity and stability of the connection structure.

[0069] refer to Figure 1 In some embodiments, the surface of the connecting rod 1 is provided with a center mark line 15, which is located at the midpoint between the raised structure 12 and the mark color line 14 and at the end of the raised structure 12 to the tail end 16 of the connecting rod 1.

[0070] refer to Figure 5 The two ends of the support sleeve 3 are aligned with the center mark line 15, so that the distance H1 between the end of the insertion end 11 and the bracket 21 is equal to the distance H2 between the end of the tail end 16 and the bracket 21.

[0071] The distance between the insertion end 11 and the bracket 21 is equal to the distance between the tail end 16 and the bracket 21, which helps to achieve overall force balance and avoid stress concentration or poor contact caused by eccentric or misaligned installation.

[0072] The spacing between the center marking lines 15 has a second preset correspondence with the length of the support sleeve 3, which can ensure that the support sleeve 3 can be accurately fitted and maintain symmetry and stability without additional measurement during installation. This not only simplifies the on-site operation process, but also effectively improves the overall structural symmetry and mechanical stability of the connecting components.

[0073] In some embodiments, the length of the connecting rod 1 ranges from 55cm to 95cm, for example, it can be 55cm, 60cm, 65cm, 70cm, 75cm, 80cm, 85cm, 90cm or 95cm. The different length specifications are designed to adapt to the actual installation needs under different wiring conditions and construction scenarios.

[0074] The length of connecting rod 1 corresponds to the spacing between the conductors at both ends of connecting rod 1, so as to ensure that the connection structure has sufficient overlap area and mechanical stability.

[0075] For example, a 55cm long connecting rod 1 is suitable for situations where the distance between the conductors at both ends of the connecting rod 1 is 17cm to 23cm; a 75cm long connecting rod 1 is suitable for situations where the distance between the conductors at both ends of the connecting rod 1 is 24cm to 30cm; and a 95cm long connecting rod 1 is suitable for situations where the distance between the conductors at both ends of the connecting rod 1 is 31cm to 40cm.

[0076] The above correspondence takes into account conductivity, mechanical strength, and ease of installation. Selecting a suitable length of connecting rod 1 based on the actual measured conductor spacing ensures the stability and electrical continuity of the connection structure. This standardized length and spacing matching design helps improve installation efficiency and reduce material waste.

[0077] refer to Figure 7 In some embodiments, the connecting rod 1 is a telescopic structure, including an inner rod 17, an outer tube 18, and a locking device 19. The inner rod 17 is nested inside the outer tube 18 and can slide axially within a certain range to achieve continuous adjustment of the overall length of the connecting rod, so as to adapt to the connection requirements of conductors with different spacings and improve the versatility of the components and construction efficiency.

[0078] The locking device 19 is used to adjust the length of the connecting rod 1. In the locked state, the inner rod 17 and the outer tube 18 maintain a stable relative position to prevent the length of the connecting rod 1 from changing due to external force.

[0079] In some embodiments, the locking device 19 includes a threaded knob disposed on the side wall of the outer tube 18, the threaded knob abutting against the inner rod 17 for locking the length of the connecting rod 1.

[0080] The threaded knob includes a head and a tail. The head is located outside the outer tube 18, and the tail is located inside the outer tube 18. By rotating the head of the threaded knob, the tail is pressed against the inner rod 17, thereby fixing the current length of the connecting rod 1 and ensuring the structural stability of the connecting rod 1 during use. In addition, using a threaded knob as a locking method has the advantages of simple operation, reliable structure, and strong reusability, further improving the overall performance of the connecting components.

[0081] The locking device plays a crucial role in enabling the adjustment and fixation of the connecting rod length. Besides the threaded knob structure, various other forms of locking devices can be used, such as snap-lock structures and rotary locking sleeve structures, to meet the requirements of different application scenarios regarding ease of operation, structural strength, and adjustment precision.

[0082] refer to Figure 6 In some embodiments, the connecting member further includes a fixing member 4, which is located on both sides of the rotating nut retainer 2 and is used to fix the insertion end 11 and the tail end 16.

[0083] In some embodiments, when the insertion end 11 and the tail end 16 extend a large length, they are prone to bending or sagging due to gravity, which affects the stability of the electrical connection. By binding the insertion end 11 and the tail end 16 to the main body of the connecting rod 1 with the fastener 4, additional support points are provided to limit their free swinging or sinking. This not only improves the rigidity of the overall structure but also avoids the risk of poor contact or mechanical damage caused by the sagging of the ends.

[0084] In some embodiments, the fastener 4 may be a binding structure such as nylon cable ties, metal buckles or flexible straps to bind and fix the insertion end 11 and tail end 16 of the connecting rod 1 to the main body of the connecting rod 1, forming additional mechanical constraints.

[0085] The connecting component provided in this disclosure allows for flexible material replacement of the connecting rod according to the actual application environment, thereby meeting different functional requirements. For example, it can achieve stable conductive connection in high-current protection scenarios, and also achieve electrical insulation in scenarios requiring isolation. The rotating nut retainer secures the connecting rod through mechanical locking, which helps improve the stability and reliability of the connection structure.

[0086] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes in form and detail may be made without departing from the spirit and scope of this disclosure. Any person skilled in the art can make various alterations and modifications without departing from the spirit and scope of this disclosure; therefore, the scope of protection of this disclosure should be determined by the scope defined in the claims.
