Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a cable connection structure with heat dissipation resistance and the cable thereof. Background Technology

[0002] A cable is a conductor made of one or more mutually insulated conductors and an outer insulating protective layer. It is laid underground, in the air, etc. Cables are characterized by being energized internally and insulated externally.

[0003] In traditional cable usage, multiple cables are often connected end to end to achieve long-distance power transmission. At the connection point, wires are usually wrapped around the connection, and then an insulation layer is wrapped around the outside. However, because the connection point lacks a heat-conducting structure design, when a short circuit occurs at the cable connection point, a large amount of heat accumulates and cannot be dissipated in time, causing the temperature to soar, which can lead to serious safety accidents such as fires or melting. In addition, in the event of an external fire, the low heat resistance of traditional cables can easily cause the outer sheath to melt, exposing the internal wires and causing leakage accidents. Utility Model Content

[0004] The purpose of this invention is to solve the problems of traditional cables lacking internal heat-conducting structure design and having low heat resistance, and to provide a cable connection structure and cable with heat dissipation resistance.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a cable connection structure with heat dissipation resistance, including...

[0007] The cable has conductor connectors at both ends for energizing the two cables; cable connecting cylinders are fixed to the outside of the conductor connectors for connecting and isolating the conductor connectors between the cables; each cable connecting cylinder is connected to a vent pipe with a valve for controlling the exchange of air inside the cable connecting cylinder.

[0008] A heat-conducting cylinder is sleeved on the cable, with both ends of the heat-conducting cylinder located inside the cable connecting cylinder. The inner side of the heat-conducting cylinder has several protrusions, and gap grooves are formed between the protrusions. A temperature sensor is installed on the heat-conducting cylinder.

[0009] Furthermore, the protrusions are elongated and arranged in a circumferential array.

[0010] Furthermore, the two cable connecting cylinders are respectively a first connecting cylinder and a second connecting cylinder; the first connecting cylinder is fixedly sleeved on the cable; the second connecting cylinder includes a connecting cylinder body, one end of which is fixedly sleeved on the cable, and the other end of which is rotatably connected to a connecting head, the connecting head being threadedly engaged with the first connecting cylinder.

[0011] Furthermore, the main body of the connecting cylinder is rotatably connected to the connecting head via a bearing.

[0012] Furthermore, a sealing ring is provided on the inner side of the first connecting cylinder.

[0013] Furthermore, a desiccant box is detachably provided inside the vent pipe for holding desiccant.

[0014] Furthermore, the heat-conducting cylinder is made of polyvinyl chloride.

[0015] This utility model also provides a cable, which includes any of the above-described connection structures.

[0016] Furthermore, the cable includes a conductor, a conductor connector is connected to the conductor, an insulating layer is wound around the outside of the conductor, a heat-conducting cylinder is sleeved on the outside of the insulating layer, a metal wire mesh is sleeved on the outside of the heat-conducting cylinder, a rubber layer is sleeved on the outside of the metal wire mesh, and a fireproof layer is sleeved on the outside of the rubber layer.

[0017] The beneficial effects of this utility model are:

[0018] 1. By incorporating a heat-conducting cylinder and a temperature sensor, when a short circuit occurs in the cable, a large amount of heat accumulates. The temperature sensor can promptly report internal temperature changes, increasing visibility and facilitating timely prevention and control, thus reducing property damage. The heat-conducting cylinder rapidly disperses and conducts the accumulated heat away, effectively preventing temperature rise and potential safety accidents. Furthermore, the spaced protrusions prevent the inner wall of the heat-conducting cylinder from completely adhering to the conductor, creating gaps that allow for ventilation into the cable, enabling faster expulsion of hot air and further cooling, ensuring safe operation.

[0019] 2. By adding a fireproof layer, the impact of external fires on the cables is reduced, preventing cable damage and losses, greatly improving the heat resistance of the cables, and also reducing the risk of cable leakage. Attached Figure Description

It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention.

[0029] like Figures 1-6 As shown

[0030] A cable connection structure with heat dissipation resistance and its cable are disclosed. The cable 1 includes a conductor 16, an insulation layer 15 is wound around the outside of the conductor 16, and a heat-conducting cylinder 14 with a cylindrical structure is sleeved on the outside of the insulation layer 15. Specifically, the heat-conducting cylinder 14 can be detachably connected to the cable 1 by means of a clamp. With this solution, it is convenient to connect both ends of the cable 1 to external equipment after it is detached.

[0031] Furthermore, the inner side of the heat-conducting cylinder 14 is provided with elongated protrusions 141 arranged in a circular array, and the heat-conducting cylinder 14 is provided with a temperature sensor 4 for detecting temperature; and preferably, the heat-conducting cylinder 14 is made of polyvinyl chloride.

[0032] With this solution, when a short circuit occurs in cable 1 at a certain point, a large amount of heat accumulates. Temperature sensor 4 can promptly report internal temperature changes, increasing visibility and facilitating timely prevention and control, thus reducing property damage. The heat-conducting cylinder 14 allows the accumulated heat to be quickly dispersed and dissipated, effectively preventing temperature rise and potential safety accidents. Furthermore, the spaced protrusions 141 prevent the inner wall of the heat-conducting cylinder 14 from completely adhering to the conductor 16, creating gaps 142 that facilitate air exchange into the cable 1, allowing hot air to escape more quickly and achieving cooling, further ensuring safety. In addition, polyvinyl chloride (PVC) is a commonly used material for the rubber layer 12 of cable 1, possessing excellent heat resistance and conductivity. The use of PVC in the heat-conducting cylinder 14 and the rubber layer 12 creates a double-layer protection and heat-conducting structure, resulting in superior performance.

[0033] Furthermore, a metal wire mesh 13 is fitted around the outside of the heat-conducting cylinder 14;

[0034] This solution effectively increases the toughness of the cable 1, prevents breakage, and prevents the internal conductor 16 from being exposed, thus reducing the incidence of safety accidents.

[0035] Furthermore, a rubber layer 12 is provided on the outside of the metal wire mesh 13, and a fireproof layer 11 is provided on the outside of the rubber layer 12;

[0036] Preferably, the fireproof layer 11 is made of fireproof cotton.

[0037] By adding the fireproof layer 11 through this solution, not only is the impact of an external fire on cable 1 reduced, preventing cable damage and losses, but the risk of cable 1 leakage is also reduced.

[0038] Specifically, both ends of the conductor 16 are provided with conductor connectors 3. Furthermore, the two conductor connectors 3 have a concave-convex plug-in structure, which facilitates end-to-end connection for conductivity. Cable connector cylinders 2 are fixed on the outside of the conductor connectors 3 for connecting and isolating the conductor connectors 3 between cables 1.

[0039] Specifically, the cable connecting cylinders 2 sleeved at both ends of the cable 1 are a first connecting cylinder 23 and a second connecting cylinder 24, respectively. The first connecting cylinder 23 is fixedly sleeved on the outside of the cable 1, and its inner side wall is provided with internal threads. The second connecting cylinder 24 includes a connecting cylinder body 242, one end of which is fixedly sleeved on the cable 1, and the other end of which is provided with a bearing 2421. The inner ring of the bearing 2421 is provided with a connecting head 241 that is also cylindrical. Specifically, the other end of the connecting head 241 is provided with external threads for the first connecting cylinder 23 to be threaded together.

[0040] This solution facilitates the connection of multiple cables end-to-end for power transmission.

[0041] Preferably, a sealing ring 22 is provided on the inner side of the first connecting cylinder 23. This solution facilitates the sealing of the first connecting cylinder 23 and the second connecting cylinder 24 after they are connected, so as to form a closed space inside and prevent external influences on the inside of the cable 1.

[0042] Furthermore, both the first connecting cylinder 23 and the second connecting cylinder 24 are connected to a vent pipe 21, and the vent pipe 21 is equipped with a valve 211 to control the air inside the exchange cable connecting cylinder 2.

[0043] Preferably, an air-permeable desiccant box 212 containing desiccant is detachably embedded in the air inlet end of the vent pipe 21 via a transition fit.

[0044] This method ensures that dry, cold air is introduced when ventilating the inside of cable 1, thus improving safety during use.

[0045] How this device works:

[0046] When long-distance power transmission is required, before use, the conductor connectors 3 at both ends of several cables 1 are plugged into each other to ensure power transmission. Then, the first connecting sleeve 23 and the second connecting sleeve 24 are screwed together end to end. After the connection is completed, the first connecting sleeve 23 and the second connecting sleeve 24 at both ends of the whole are removed, so that the whole can connect the external power supply equipment and the power consumption equipment to realize power supply. When the temperature sensor 4 on a certain section of cable 1 detects a significant increase in temperature, it indicates that there may be a short circuit or excessive current at some point inside this section of cable 1, causing the cable 1 to overheat and accumulate a large amount of heat. At this time, the heat-conducting cylinder 14 evenly conducts heat to all parts, reducing the risk of heat accumulation. Then, the valve 211 on the vent pipe 21 on the cable connecting cylinder 2 is opened to prepare to blow in cold air. Before blowing in cold air, a desiccant box 212 containing desiccant should be placed on the air inlet end of the vent pipe 21 to ensure that the blown-in cold air is dry. After installation, cold air is circulated into the cable 1 through the existing external equipment. A large amount of dry cold air is conducted to all parts of the cable 1 through the gap groove 142 on the heat-conducting cylinder 14 and hot air is discharged, thereby reducing the temperature inside the cable 1 in time and achieving heat dissipation.

[0047] When an external fire occurs, the above operations can also be used to ensure that the internal temperature of cable 1 is maintained within a certain safe range, and the flame-retardant effect is even better when combined with the external fireproof layer 11.

[0048] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
