[0002] Copper core cables are a common type of equipment, often used in various complex industrial environments to ensure stable power transmission. To ensure the service life of copper core cables, it is usually necessary to design them with insulation and protection properties.

[0003] Meanwhile, a copper-core PVC-sheathed cable with application number CN202221756904.3 includes a conductor, a filler layer, and a support rod. An inner shielding layer is installed outside the conductor, an insulation layer is installed outside the inner shielding layer, an outer shielding layer is installed outside the insulation layer, a soft copper tape layer is installed outside the outer shielding layer, the filler layer is disposed outside the soft copper tape layer, a wrapping layer is disposed outside the filler layer, an outer sheath is disposed outside the wrapping layer, and the support rod is connected to the outer sheath. One end of the support rod is connected to a baffle. The beneficial effects are: by setting up the support rod, baffle, and protective net, this utility model allows a gap to be left between the baffle and the cable through the support rod, and the baffle blocks soil. During cable operation, the cable heat flows through the space between the baffle and the cable, and moves to the soil through the protective net, improving the cable's heat dissipation efficiency and reducing the cable's operating temperature.

[0004] However, the following problems were found in the implementation of the relevant technology: Although the existing equipment can provide sufficient insulation and protection for the internal copper core of the cable, the stability of the connection between the equipment and the external structure is not high enough, and the connection is prone to loosening. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an elastomeric insulating sheath for copper core cables, which has the advantages of being connected to an external structure by two fixing screws, and being able to buffer vibrations by springs on the sidewalls of the fixing screws to prevent loosening at the connection when subjected to external impact.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an elastomeric insulating sheath for copper core cables, comprising a copper core cable and a rubber sheath fitted over the outside of the copper core cable. The outer wall of the rubber sheath is constructed with multiple sets of threads arranged side by side, and a connecting ring is threadedly connected to the outer wall of the rubber sheath. A connecting strip is integrally formed at the bottom of the connecting ring, and a fixing strip is integrally formed at the bottom of the connecting strip. Two fixing holes are symmetrically opened at the top of the fixing strip, and fixing screws are movably inserted into the fixing holes. A spring is fitted on the side wall of the fixing screw, and washers are connected to both sides of the spring. The two washers abut against the head of the fixing screw and the corresponding side of the fixing strip, respectively.

[0007] Preferably, an insulating layer is sleeved on the outside of the copper core of the cable, and a shielding layer is sleeved on the outside of the insulating layer, with the shielding layer located inside the rubber sleeve.

[0008] Preferably, the connecting ring and the connecting strip, as well as the connecting strip and the fixing strip, are all injection-molded integral structures.

[0009] Preferably, both sides of the connecting ring abut against the limiting ring, and the limiting ring is threadedly connected to the corresponding side of the rubber sleeve.

[0010] Preferably, the outer walls of the limiting ring and the connecting ring are flush, and the outer wall of the limiting ring is provided with anti-slip texture.

[0011] Preferably, a rubber layer is bonded to the bottom of the fixing strip, and the rubber layer is flush with the edge of the fixing strip.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses two fixing screws to connect with the external structure to fix the equipment. When the equipment is subjected to external impact, the spring on the side wall of the fixing screw will buffer the vibration through elastic deformation in conjunction with the washers on both sides, thereby preventing the connection with the external structure from loosening and making the connection more stable.

[0014] 2. This utility model uses the connecting ring and related structure that come with the equipment for connection and fixation. There is no need to carry an additional fixing structure. The staff only needs to tighten two fixing screws to complete the connection and fixation, which makes the connection and fixation more convenient.

[0015] 3. This utility model can prevent leakage of the copper core of the cable through the insulation layer, and the shielding layer can shield electrical signals. In addition, the external rubber sleeve can provide sufficient insulation protection for the copper core of the cable. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides an elastomeric insulating sheath for copper core cables, including a copper core 1 and a rubber sleeve 2 fitted over the outside of the copper core 1. The rubber sleeve 2 is a commonly used structure in the art. Multiple sets of threads are arranged side-by-side on the outer wall of the rubber sleeve 2, and a connecting ring 3 is threadedly connected to the outer wall of the rubber sleeve 2. The threaded connection of the connecting ring 3 allows for direction adjustment to adapt to the desired direction of fixing external structures, making installation more flexible. A connecting strip 4 is integrally formed at the bottom of the connecting ring 3, and a fixing strip 5 is integrally formed at the bottom of the connecting strip 4. This integrally formed structure is less prone to damage. The top of the fixing strip 5 has two symmetrical fixing holes, and a fixing screw 6 is movably inserted into the fixing hole. A spring 8 is sleeved on the side wall of the fixing screw 6. Washers 7 can be connected to both sides of the spring 8. When the equipment is subjected to external impact, the fixing strip 5 will vibrate relative to the fixing screw 6. At this time, the two washers 7 will compress the spring 8. The spring 8 can buffer the vibration through elastic deformation, so that the connection between the fixing screw 6 and the external structure remains stable and prevents the connection from loosening. The two washers 7 respectively abut against the head of the fixing screw 6 and the corresponding side of the fixing strip 5.

[0023] Specifically, an insulation layer 10 is sleeved on the outside of the copper core 1 of the cable, which provides insulation performance for the copper core 1 of the cable using existing principles. A shielding layer 11 is sleeved on the outside of the insulation layer 10, which can shield electrical signals using existing principles, and the shielding layer 11 is located inside the rubber sleeve 2.

[0024] Furthermore, the connection between the connecting ring 3 and the connecting strip 4, and the connection between the connecting strip 4 and the fixing strip 5, are all injection-molded integral structures. The injection-molded integral structure has high structural strength, is not easy to break or be damaged, and is more durable.

[0025] Furthermore, both sides of the connecting ring 3 abut against the limiting rings 9, and the limiting rings 9 are threadedly connected to the corresponding sides of the rubber sleeve 2. The two limiting rings 9 can limit the adjusted connecting ring 3 to prevent it from shaking relative to the rubber sleeve 2 and increase stability.

[0026] It is worth noting that the outer walls of the limiting ring 9 and the connecting ring 3 are flush, which increases the integrity and aesthetics of the overall structure. In addition, the outer wall of the limiting ring 9 is provided with anti-slip texture, making it easy to turn the limiting ring 9 by hand.

[0027] It is worth noting that a rubber layer 12 is bonded to the bottom of the fixing strip 5, and the rubber layer 12 is flush with the edge of the fixing strip 5, which can increase the friction on the corresponding side of the fixing strip 5 and help improve the stability of the connection with the external structure.

[0028] Among them, the copper core 1 of the cable is existing technology and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0029] Working principle: Tighten the connecting ring 3 so that the fixing strip 5 faces the external structure to be connected and fixed. Then tighten the limiting rings 9 on both sides to abut against the connecting ring 3. Then tighten the two fixing screws 6 to complete the fixing of the fixing strip 5. When the equipment is subjected to external impact, the impact force will be transmitted to the surface of the fixing strip 5. At this time, the fixing strip 5 will vibrate relative to the fixing screws 6 fixed to the external structure. During this process, the two washers 7 will compress the springs 8. The vibration is buffered by the elastic deformation of the two springs 8, so that the connection is not easy to loosen.
