Description

Technical Field

[0001] The utility model relates to the technical field of cable transmission, in particular to a self-adsorption soft cable. Background Art

[0002] With the rapid development of communication technology, the current carrying capacity and transmission speed of cables are increasing. Existing soft cables for communication power supply are all installed in the traditional bridge frame. It is easy for cables to pile up in the bridge frame pipe, so that the heat generated by the cable transmission cannot be dissipated in time, resulting in serious heating of the cable, which poses certain safety hazards.

[0003] In the prior art, cables are usually installed by laying them on the ground or laying them in bundles. The above cable installation methods are difficult to operate and will make the distance between cables too close, resulting in low heat dissipation efficiency of the cables. In addition, since the cables laid on the ground are in contact with the ground, the cables laid in bundles are piled up, the safety factor of cable laying is reduced. Utility Model Content

[0004] One purpose of the utility model is to provide a self-adsorption soft cable to solve the technical problem in the prior art that the heat dissipation efficiency is poor due to the short cable installation distance.

[0005] Another object of the utility model is to improve the adsorption performance of the cable.

[0006] According to the purpose of the utility model, the utility model provides a self-adsorbing soft cable, including:

[0007] At least one wire core, each of the wire cores comprising a conductor and an insulating layer sheathed around the conductor;

[0008] A sheath, which is sleeved on the outer circumference of all the wire cores;

[0009] The adsorption layer is arranged along the length direction of the sheath, and the adsorption layer is attached to the outer peripheral side of the sheath.

[0010] Optionally, the adsorption layer comprises:

[0011] A plurality of adsorption members are sequentially arranged along the length direction of the sheath, and a preset distance is provided between two adjacent adsorption members.

[0012] Optionally, the ratio of the preset distance to the length of the adsorption component is any value in the range of 1:2-2:1.

[0013] Optionally, the ratio of the width of the adsorption member to the diameter of the sheath is any value in the range of 1:4-1:8.

[0014] Optionally, the length of the adsorption member is any value in the range of 180 mm-220 mm.

[0015] Optionally, it also includes:

[0016] The adhesive layer is arranged between the adsorption layer and the sheath.

[0017] Optionally, the material of the adhesive layer is epoxy resin.

[0018] Optionally, the insulating layer and the sheath are both made of fluorosilicone rubber.

[0019] Optionally, the adsorption element is a bar magnet.

[0020] The utility model provides an adsorption layer on the outer surface of the cable sheath so that each cable can be adsorbed at a position to be fixed, thereby reducing the difficulty of cable installation and increasing the installation distance between cables, thereby improving the heat dissipation efficiency of the cable.

[0021] Furthermore, when the ratio of the width of the adsorption piece of the cable of the utility model to the diameter of the sheath is 1:6, the adsorption force of the adsorption layer of the cable on the bridge is the greatest, that is, the stability of the cable adsorption on the bridge is the highest, and the material usage can be saved to a minimum, thereby reducing the manufacturing cost of the cable.

[0028] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0032] Figure 1 is a schematic structural diagram of a cable according to an embodiment of the utility model, Figure 2 is a schematic cross-sectional view of a clamping portion according to an embodiment of the utility model. Figure 1 to Figure 2 As shown, the utility model provides a self-adsorbing flexible cable 100. The cable 100 includes at least one core 10, a sheath 20 and an adsorption layer 30. Each core 10 includes a conductor 11 and an insulating layer 12 sheathed on the circumference of the conductor 11. The sheath 20 is sheathed on the outer circumference of all the cores 10. The adsorption layer 30 is arranged along the length direction of the sheath 20, and the adsorption layer 30 is attached to the outer circumference of the sheath 20. Here, the insulating layer 12 is made of the same material as the sheath 20, and the number of the cores 10 can be one or more.

[0033] In this embodiment, the cable 100 is sequentially arranged with a core 10, a sheath 20 and an adsorption layer 30 from the inside to the outside, and the sheath 20 is used to prevent the core 10 from being mechanically damaged during installation and use, and to prevent environmental factors such as moisture, chemical corrosion, ultraviolet rays and ozone from causing irreversible damage to the cable 100. Specifically, by arranging the adsorption layer 30 on the outer surface of the sheath 20 of the cable 100, each cable 100 can be adsorbed at the position to be fixed, reducing the difficulty of installing the cable 100, and increasing the installation distance between the cables 100, thereby improving the heat dissipation efficiency of the cable 100.

[0034] In this embodiment, the number of the wire cores 10 is three, and the cable 100 further includes a filler 50 and a wrapping tape 60. The filler 50 is located in the cavity between the wire core 10 and the sheath 20, and the wrapping tape 60 is used to fix the three wire cores 10. The filler 50 is used to protect the cable 100 and improve the insulation performance of the cable 100, prevent the wire cores 10 in the cable 100 from being mechanically damaged during use, reduce the interference between the cable 100 and the external environment, and prevent the different components of the cable 100 from having harmful effects on each other. Here, the materials of the filler 50 and the wrapping tape 60 can be polypropylene or polyester.

[0035] In this embodiment, the adsorption layer 30 includes a plurality of adsorption members 31 arranged in sequence along the length direction of the sheath 20, and a preset distance is spaced between two adjacent adsorption members 31. Specifically, the plurality of adsorption members 31 are evenly spaced and arranged along the length direction of the sheath 20, which facilitates the bending of the cable 100, that is, facilitates the installation of the cable 100 at a corner, thereby increasing the convenience of installing the cable 100.

[0036] In this embodiment, the ratio of the preset distance to the length of the adsorption member 31 is any value in the range of 1:2-2:1, so that the cable 100 is firmly laid in a fixed place to avoid concentrated accumulation of the cables 100. Specifically, the ratio of the preset distance to the length of the adsorption member 31 can be 1:2, 1:1 or 2:1, or any other value in the range of 1:2-2:1.

[0037] In a preferred embodiment, the ratio of the preset distance to the length of the adsorption member 31 is 1:1, which can ensure the adsorption of the adsorption layer 30 while maximizing the bendability of the cable 100 and facilitating the installation of the cable 100 .

[0038] In this embodiment, the ratio of the width of the adsorbent 31 to the diameter of the sheath 20 is any value in the range of 1:4-1:8, so that the cable 100 can be stably adsorbed at the position to be fixed. Specifically, the ratio of the width of the adsorbent 31 to the diameter of the sheath 20 can be 1:4, 1:5, 1:6, 1:7 or 1:8, or any other value in the range of 1:4-1:8.

[0039] In a preferred embodiment, when the ratio of the width of the adsorption member 31 to the diameter of the sheath 20 is 1:6, the adsorption force of the adsorption layer 30 of the cable 100 on the bridge is the greatest, that is, the stability of the cable 100 adsorbed on the bridge is the highest, and the amount of material used can be saved to a minimum, thereby reducing the manufacturing cost of the cable 100.

[0040] In this embodiment, the length of the adsorption member 31 is any value in the range of 180 mm-220 mm, so that the cable 100 can be stably adsorbed at the position to be fixed, while avoiding the reduction of bendability due to the excessive length of the adsorption member 31. Specifically, the length of the adsorption member 31 can be 180 mm, 190 mm, 200 mm or 220 mm, or any other value in the range of 180 mm-220 mm.

[0041] In a preferred embodiment, the length of the adsorption member 31 is 200 mm, and the preset distance between two adjacent adsorption members 31 is 200 mm. The cable 100 can ensure the bending performance of the cable 100 while ensuring the stability of the cable 100 adsorbed at the position to be fixed.

[0042] In this embodiment, the cable 100 further includes an adhesive layer 40 , which is disposed between the adsorption layer 30 and the sheath 20 and is used to fix the adsorption member 31 , so that the cable 100 is adsorbed at a position to be fixed by the adsorption member 31 .

[0043] In this embodiment, the material of the adhesive layer 40 is epoxy resin. Specifically, the adhesive layer 40 is made of modified epoxy resin, so that the temperature resistance level of the adhesive layer 40 is the same as that of the cable 100 material, so as to prevent the adhesive layer 40 from being heated and unable to fix the adsorbent 31 when the temperature of the cable 100 is high, thereby preventing the cable 100 from falling off when the temperature of the cable 100 is high.

[0044] In this embodiment, the insulating layer 12 and the sheath 20 are both made of fluorosilicone rubber, which improves the high temperature resistance of the cable 100 and increases the current carrying capacity of the cable 100 during high temperature transmission.

[0045] In this embodiment, the adsorption member 31 is a bar magnet, and a plurality of bar-shaped adsorption members 31 are arranged along the extension direction of the cable 100. In other embodiments, the adsorption member 31 may be a ring magnet.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
