Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a light communication cable. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Cables are usually used in combination with cable reels. In recent years, low-voltage cables have been used in large quantities and in many varieties. Low-voltage power cables are commonly used materials in power engineering and communication engineering.

[0003] The current cables are heavy, which causes great inconvenience in installation and transportation. After studying the inside of the cable, we found that in order to ensure its own hardness, the cable will fill a high-density substance between the inside of the protective shell and the outside of the cable, and fill the inside of the protective shell, thereby providing good protection for the cable. Based on this, we propose a communication cable that can be lightweight while ensuring the stability of existing cables. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a lightweight communication cable to solve the technical problems mentioned in the above background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lightweight communication cable, comprising a protective shell, a cavity is opened inside the protective shell, and a plurality of groups of annularly distributed cables are arranged inside the cavity for signal transmission, a support ring is arranged inside the cavity, and the inner side of the support ring is connected to a support frame for improving the supporting capacity of the support ring.

[0006] By adopting the above technical solution and utilizing lightweight and high-strength materials, the weight of the entire cable can be greatly reduced, and the hardness of the cable is also ensured accordingly.

[0007] The utility model is further configured such that the outer wall of the cable is arranged in close contact with the inner wall of the protective shell and the outer wall of the support ring to achieve preliminary positioning of the cable.

[0008] By adopting the above technical solution, the cables can be limited and fixed.

[0009] The utility model is further configured such that the support ring and the support frame are both made of high-strength and lightweight materials.

[0010] By adopting the above technical solution, a lightweight effect is achieved.

[0011] The utility model is further configured that the outer wall of the support ring is fixedly provided with a plurality of sleeves annularly distributed on the outer wall of the support ring, and the interior of the sleeve is provided with a moving rod extending to the outside of the sleeve.

[0012] By adopting the above technical solution, an auxiliary buffering effect is achieved.

[0013] The utility model is further configured such that the end of the moving rod is fixedly connected to a force-bearing portion that is fitted on the inner wall of the protective shell, and the outer wall of the sleeve is fixedly connected to a limiting clamping rod that extends to the outer wall of the cable to achieve secondary limiting of the cable, a sliding groove is provided inside the sleeve, and the moving rod is slidably connected to the sliding groove, and a return spring connected to the outer wall of the moving rod is installed inside the sliding groove.

[0014] By adopting the above technical solution, a buffering effect is achieved on the protective shell.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] 1. The utility model provides a support ring, a support frame and a limit rod, and adopts a support ring to replace the original filler, which greatly reduces the overall weight of the cable, and installs the cable between the support ring and the inner wall of the protective shell. The extrusion effect of the support ring is used to make the cable initially limited in the installation position. In addition, the limit rod can further limit the cable, thereby reducing the overall weight of the cable while ensuring the installation stability of the cable;

[0017] 2. The utility model provides a sleeve, a moving rod, a sliding groove and a reset spring. The moving rod can support the protective shell through the force-bearing part. When the external force exceeds the critical value of the deformation force of the reset spring, the moving rod will move inward and squeeze the reset spring to deform to absorb potential energy. At the same time, the protective shell will also deform to absorb potential energy. Therefore, when facing external impact on the cable, it can absorb external energy well, thereby protecting the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] A lightweight communications cable, such as Figure 1-4 As shown, it includes a protective shell 1, a cavity 2 is opened inside the protective shell 1, and a plurality of groups of cables 3 distributed in an annular manner are arranged inside the cavity 2 for signal transmission, a support ring 4 is arranged inside the cavity 2, and a support frame 5 for improving the support capacity of the support ring 4 is connected to the inner side of the support ring 4;

[0026] Furthermore, in this embodiment, the support ring 4 and the support frame 5 are both made of high-strength and lightweight materials, specifically carbon fiber, glass fiber, etc.

[0027] See also Figure 2 The outer wall of the cable 3 is arranged close to the inner wall of the protective shell 1 and the outer wall of the support ring 4 to achieve the initial positioning of the cable 3. The outer wall of the sleeve 6 is fixedly connected with a positioning rod 8 extending to the outer wall of the cable 3 to achieve the secondary positioning of the cable 3, to achieve the positioning support of the cable 3 and ensure the stability of its installation. Specifically, the positioning rod 8 connected between the outer walls of multiple groups of cables 3 can integrate the multiple groups of cables 3 into a whole, so that the cables 3 between every two groups will be restricted by the positioning rod 8 and cannot be displaced, that is, the secondary positioning effect of the cable 3 is achieved.

[0028] See also Figure 2-3 The outer wall of the support ring 4 is fixedly provided with multiple groups of sleeves 6 annularly distributed on the outer wall of the support ring 4, and the interior of the sleeve 6 is provided with a moving rod 10 extending to the outside of the sleeve 6, and a slide groove 9 is opened inside the sleeve 6, and the moving rod 10 is slidably connected to the slide groove 9, and a return spring 11 connected to the outer wall of the moving rod 10 is installed inside the slide groove 9. The rigidity of the return spring 11 is used to support the protective shell 1, and the flexibility of the return spring 11 can also be used to buffer the protective shell 1.

[0029] See also Figure 2The end of the moving rod 10 is fixedly connected to a force-bearing part 7 that is fitted on the inner wall of the protective shell 1, so as to achieve support and buffering effects on the protective shell 1. Specifically, the force-bearing part 7 is arranged between every two groups of cables 3, and the top end face of each group of force-bearing parts 7 is in contact with the inner wall of the protective shell 1 of the cable 3. Therefore, when the protective shell 1 is deformed due to impact, the deformation of the protective shell 1 will squeeze the force-bearing part 7. If the impact force does not exceed the deformation force of the reset spring 11, the force-bearing part 7 will support the protective shell 1, that is, prevent the protective shell 1 from further deformation. If the impact force exceeds the deformation force of the reset spring 11, the force-bearing part 7 will move inward to squeeze the reset spring 11, thereby buffering the impact force.

[0030] The working principle of the utility model is as follows: the support ring 4 is used to replace the original filler, which greatly reduces the overall weight of the cable 3, and the cable 3 is installed between the support ring 4 and the inner wall of the protective shell 1, and the cable 3 can be initially limited in the installation position by utilizing the squeezing effect of the support ring 4. In addition, the limit clamping rod 8 can further limit the cable 3, thereby reducing the overall weight of the cable 3 while also ensuring the installation stability of the cable 3;

[0031] In addition, the moving rod 10 can achieve a supporting effect on the protective shell 1 through the force-bearing part 7. When the external force exceeds the critical value of the deformation force of the reset spring 11, the moving rod 10 will move inward and squeeze the reset spring 11 to deform to absorb potential energy. At the same time, the protective shell 1 will also deform to absorb potential energy. Therefore, when facing external impact on the cable 3, it can absorb external energy well, thereby protecting the cable 3.
