Description

Technical Field

[0001] This utility model relates to the field of communication cable technology, specifically a durable multi-core communication cable with a breakage warning function. Background Technology

[0002] Durable multi-core communication cable with fault-detection warning is a cable specifically designed for high-reliability communication scenarios. Combining a durable structure with intelligent early warning functions, it is widely used in industrial automation, smart grids, traffic signal systems, and other fields. It is specifically designed for scenarios requiring long-term stable operation and stringent fault response requirements. As a multi-core communication cable, it contains multiple independent cores, such as 4-core, 8-core, or 12-core cables, capable of simultaneously transmitting data, voice, video, or control signals.

[0003] In existing technologies, such as the flexible and pressure-resistant multi-core communication cable disclosed in CN222319833U, the cable includes: a cable comprising an outer sheath, an armor layer fixedly connected to the inner wall of the outer sheath, an inner sheath fixedly connected to the inner wall of the armor layer, a conductor fixedly connected to the inner cavity of the inner sheath, and an insulation layer fixedly connected to the outer wall of the conductor; a connector fixedly connected to the outer circumference of the cable end; a clamping mechanism comprising a sleeve fitted onto the outer wall of the cable; and a fixing mechanism comprising support rods fixedly connected to the four corners of the top outer wall of the sleeve. This mechanism works by rotating the corresponding rod until the support rod is in full contact with the cable, then installing a second limiting rod in the limiting hole to limit the corresponding rod and the rotating rod, thereby fixing the cable to the support rod, preventing cable rotation, reducing the workload of manual lifting, and improving cable installation efficiency.

[0004] Existing cables fix the cable to the support rod by rotating the corresponding rod until the support rod is in full contact with the cable, and then installing a second limiting rod in the limiting hole to limit the corresponding rod and the rotating rod, thus preventing the cable from rotating. However, during use, because communication cables need to undergo repeated bending actions, the core is easily broken due to bending and compressive forces, which affects the electrical characteristics of the cable for normal use. This can easily cause uncontrolled actions and misoperations of machinery and equipment, leading to sudden failures. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology has the problem that communication cables need to undergo repeated bending actions during use, the core is subjected to bending and compressive forces, which can easily lead to wire breakage, affect the electrical characteristics of the cable for normal use, and easily cause uncontrolled operation and misoperation of machinery and equipment, resulting in sudden failure.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A durable multi-core communication cable with a breakage warning feature includes an outer cable sheath and a shielding layer, wherein the shielding layer is disposed on the inner surface of the outer cable sheath, and further includes:

[0009] The inner layer is reinforced and the fastener is fixed. The inner layer is disposed inside the shielding layer and the fastener is disposed on the outer surface of the cable outer sheath.

[0010] As a further embodiment of this utility model: the reinforcing inner layer includes a fixing ring, the fixing ring is disposed inside the reinforcing inner layer, and an mounting ring is integrally fixed to the inner wall of the fixing ring.

[0011] As a further improvement of this utility model: the inner surface of the mounting ring is provided with a lubrication layer, which is made of a solid lubricating material.

[0012] As a further improvement of this utility model: a wire breakage warning core is installed inside the mounting ring, and the wire breakage warning core is slidably connected to the lubrication layer.

[0013] As a further embodiment of this utility model: three reinforcing plates that are fixedly connected to the inner reinforcing layer are integrally fixed on the outer surface of the fixing ring, and communication cable cores are arranged on the side walls of the reinforcing plates.

[0014] As a further embodiment of this utility model: the fixing member includes a fixing rod, which is fixed to the outer wall of the fixing member.

[0015] As a further improvement of this utility model: the upper end of the fixed rod is telescopically connected to an adjusting component, and the adjusting component is internally slidably connected to a limiting block that is welded to the fixed rod.

[0016] As a further improvement of this utility model: an installation plate is integrally fixed on the upper surface of the adjusting member, and a limiting bolt that abuts against and connects with the fixing rod is installed on the side wall of the adjusting member.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, through the lubrication layer, helps to reduce the lateral pressure on the wire breakage warning core when the cable is bent. The wire breakage warning core is covered with a nylon layer, which does not conduct electricity, but precisely controls the fracture sensitivity of the monitoring core by adjusting the strength and toughness of the nylon material, so that the wire breakage warning core breaks before the communication cable core breaks, thereby realizing the early warning function.

[0019] 2. This utility model uses a fixed rod to adjust the position of the cable by turning the limiting bolt on the adjusting component. The limiting block also serves to limit the movement and prevent the fixed rod from falling off due to excessive pulling. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1:

[0030] Please see Figures 1-5 This is the first embodiment of the present invention.

[0031] This embodiment provides a durable multi-core communication cable with a breakage warning system, including an outer cable sheath 1 and a shielding layer 2. The shielding layer 2 is disposed on the inner surface of the outer cable sheath 1. It also includes:

[0032] The inner layer 3 is reinforced and the fastener 4 is fastened. The inner layer 3 is located inside the shielding layer 2 and the fastener 4 is located on the outer surface of the cable outer sheath 1.

[0033] Specifically, the reinforcing inner layer 3 includes a fixing ring 31, which is disposed inside the reinforcing inner layer 3, and an mounting ring 32 is integrally fixed to the inner wall of the fixing ring 31.

[0034] Furthermore, the reinforced inner layer 3 enhances the overall strength of the cable.

[0035] Specifically, a lubricating layer 33 is provided on the inner surface of the mounting ring 32. The lubricating layer 33 is made of solid lubricating material. A wire breakage warning core 34 is installed inside the mounting ring 32. The wire breakage warning core 34 is slidably connected to the lubricating layer 33.

[0036] Furthermore, the mounting ring 32 provided inside the fixing ring 31, with a lubricating layer 33 on its inner wall, helps to reduce the lateral pressure on the wire core 34 when the cable is bent, suppressing conductor breakage, avoiding premature wire breakage warning, and helping to improve the accuracy of the warning.

[0037] Specifically, the outer surface of the fixing ring 31 is integrally fixed with three reinforcing plates 35 that are fixedly connected to the inner reinforcing layer 3, and the side wall of the reinforcing plate 35 is provided with a communication cable core 36.

[0038] Furthermore, the breakage warning core 34 is made of small-diameter tin-plated copper monofilaments twisted together. The tin plating is not for conduction, but to precisely control the breakage sensitivity of the monitoring core by adjusting the strength and toughness of the nylon material, so that the breakage warning core 34 breaks before the communication cable core 36 breaks, thereby realizing the early warning function.

[0039] In use, the communication cable is connected to the equipment. The shielding layer 2 inside the cable's outer sheath 1 effectively shields the signal, thus reducing the impact of external signals on the cable. The reinforcing inner layer 3 enhances the overall strength of the cable. The mounting ring 32 inside the fixing ring 31, with its inner wall having a lubricating layer 33, helps to reduce the lateral pressure on the breakage warning core 34 when the cable is bent, suppressing conductor breakage and preventing premature breakage warnings, thus improving the accuracy of the warning. The breakage warning core 34 uses a smaller diameter plated core. The wire is made of tin-copper monofilaments twisted together and plated with tin-copper. The tin plating layer enhances the corrosion and oxidation resistance of the copper wire and extends the service life of the core. The high conductivity of copper ensures stable transmission of the warning signal and meets the conduction requirements of the wire break alarm circuit. When an alarm is triggered, the wire break warning core 34 is covered with a nylon layer. Its function is not to conduct electricity, but to precisely control the fracture sensitivity of the monitoring core by adjusting the strength and toughness of the nylon material. This allows the wire break warning core 34 to break before the communication cable core 36 breaks, thus achieving the early warning function. The reinforcing plate 35 can separate multiple communication cable cores 36.

[0040] In summary, when this durable multi-core communication cable with line breakage warning is in use, the lubrication layer 33 helps to reduce the lateral pressure on the line breakage warning core 34 when the cable is bent. The line breakage warning core 34 is covered with a nylon layer, which does not conduct electricity, but rather precisely controls the fracture sensitivity of the monitoring core by adjusting the strength and toughness of the nylon material, so that the line breakage warning core 34 breaks before the communication cable core 36 breaks, thereby realizing the early warning function.

[0041] Example 2:

[0042] Please see Figures 1-5 This is the second embodiment of the present utility model.

[0043] Specifically, the fastener 4 includes a fixing rod 41, which is fixed to the outer wall of the fastener 4.

[0044] Furthermore, the cable can be easily fixed by the fixing component 4.

[0045] Specifically, the upper end of the fixed rod 41 is telescopically connected to an adjusting component 42, and the adjusting component 42 is internally slidably connected to a limiting block 44 that is welded to the fixed rod 41.

[0046] Furthermore, the limiting block 44 serves to limit movement and prevent the fixing rod 41 from being pulled too much and falling off.

[0047] Specifically, an installation plate 43 is integrally fixed to the upper surface of the adjusting component 42, and a limiting bolt 45 is installed on the side wall of the adjusting component 42 to abut against and connect with the fixing rod 41.

[0048] Furthermore, by turning the limiting bolt 45 on the adjusting component 42, the position of the cable can be adjusted.

[0049] In use, the mounting plate 43 can be fixed with screws by the fixing part 4, so that the fixing part 4 limits the cable. The position of the cable can be adjusted by turning the limiting bolt 45 on the adjusting part 42 by the fixing rod 41. The limiting block 44 plays a limiting role to prevent the fixing rod 41 from being pulled too much and falling off.

[0050] In summary, when this durable multi-core communication cable with breakage warning is in use, the lubrication layer 33 helps to reduce the lateral pressure on the breakage warning core 34 when the cable is bent. The breakage warning core 34 is covered with a nylon layer, which does not conduct electricity, but rather precisely controls the breakage sensitivity of the monitoring core by adjusting the strength and toughness of the nylon material, so that the breakage warning core 34 breaks before the communication cable core 36 breaks, thereby realizing the early warning function. Furthermore, the fixed rod 41 can be used to adjust the position of the cable by turning the limiting bolt 45 on the adjusting component 42. The limiting block 44 plays a limiting role to prevent the fixed rod 41 from being pulled too much and falling off.
