Description

Technical Field

[0001] The present application relates to the field of electric wires and cables, and more specifically to an environmentally friendly luminous cable. Background Art

[0002] Wires and cables refer to conductors that transmit electrical energy. In daily life, people call household wiring wires wires and power cables cables. Power cables are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station lead lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas.

[0003] Induced electricity is a type of electricity carried by the outside of a conductive device. If the internal structure of a cable is damaged during operation, induced electricity is easily generated, which can pose a safety hazard to the surrounding environment. In order to improve the practical safety of cables, shielding layers, armor layers, and grounding are generally used to avoid the generation of induced electricity. However, when the shielding layers, armor layers, or grounding wires are damaged, it is impossible to determine from the appearance of the cable whether induced electricity is generated, which poses a safety hazard to its use. Summary of the invention

[0004] In response to the shortcomings of the prior art, the present application provides an environmentally friendly luminous cable that abandons plastic materials, effectively improving the environmental friendliness of the product. At the same time, a luminous part is provided on the product, so that the staff can judge whether the cable has generated induced electricity by the light of the luminous part, thereby helping the staff to quickly eliminate safety hazards.

[0005] It can not only ensure the normal power supply of the product, but also improve the technology and aesthetics of the product through the luminous woven part, better meet the curiosity needs of consumers, and effectively promote the progress of the industry.

[0006] An environmentally friendly luminous cable comprises an inner core, an outer package wrapped around the inner core, and a luminous part arranged outside the outer package.

[0007] Furthermore, the inner core portion is composed of an elastic inner core, a copper wire arranged outside the elastic inner core, and a shielding layer arranged outside the copper wire; the copper wire is composed of a copper core and a copper core insulation layer wrapped around the outside of the copper core.

[0008] Preferably, the angles between any two adjacent copper wires are the same, and a support sheet is provided between any two adjacent copper wires.

[0009] Preferably, an inner filling layer is provided between the support sheet and the elastic inner core, and an outer filling layer is provided between the shielding layer and the support sheet.

[0010] Furthermore, the outer package is composed of an inner PVC layer wrapped outside the shielding layer, an armor layer wrapped outside the inner PVC layer, a non-woven fabric layer wrapped outside the armor layer, and an outer PVC layer wrapped outside the non-woven fabric layer.

[0011] Furthermore, the light-emitting part is composed of an outer insulating layer, a light-emitting strip arranged on the outer insulating layer, an upper conductor, a lower conductor and a light-emitting structure.

[0012] Preferably, the outer insulating layer is wrapped around the outer side of the outer PVC layer.

[0013] Preferably, the light-emitting strip is wound on the outer wall of the outer insulating layer, and the front end of the light-emitting strip penetrates the outer insulating layer; the light-emitting strip is embedded in the outer wall of the outer insulating layer.

[0014] Preferably, the lower conductor is spirally attached to the inner wall of the outer insulating layer, the upper conductor is arranged in the outer insulating layer along the axial direction of the outer insulating layer, and the two ends of the upper conductor are respectively connected to the two ends of the lower conductor; the light-emitting structure is connected in series between the upper conductor and the lower conductor.

[0015] Preferably, the light-emitting strip is an optical fiber with a transparent outer cladding, and the front end of the light-emitting strip penetrates the outer insulating layer and abuts against the light-emitting structure.

[0016] Compared with the prior art, this application has the following beneficial effects:

[0017] (1) The present invention provides a light-emitting portion so that the staff can judge whether the cable has generated induced electricity by the light emission of the light-emitting portion, thereby helping the staff to quickly eliminate safety hazards, better improve the safety of product use, reduce the difficulty of troubleshooting and maintenance, improve the efficiency of troubleshooting and maintenance, and better reduce the labor cost required for the later maintenance of the product.

[0018] (2) The elastic inner core of the present invention is made of hemp rope, which can reduce the cost of the product and effectively improve the flexibility of the cable.

[0019] (3) The copper core insulation layer and the support sheet of the present invention are both made of TPE material. The support sheet can effectively support the copper wire, which effectively prevents the copper wire from being displaced due to external forces during transportation or use, better ensures the spacing between the copper wires, and improves the safety of product use.

[0020] (4) The inner filling layer of the present invention is filled with glass fiber yarn, which has good insulation and heat resistance, and better improves the safety of product use. At the same time, the glass fiber yarn also has good mechanical strength, which can better improve the resistance of the cable to external forces, thereby better avoiding deformation of the cable due to external forces.

[0021] (5) The outer filling layer of the present invention is filled with aramid yarn, which has excellent properties such as high temperature resistance, acid resistance, alkali resistance, light weight, etc., and has extremely high strength. It can still protect the copper wire well when the outside of the cable is damaged, further improving the safety of the product.

[0022] (6) The winding length of the light strip of the present invention can be adjusted according to the actual usage. In theory, the farther the cable is from the visible distance, the longer the winding length should be. The purpose is to increase the visible area so that the staff can observe from a distance.

[0023] (7) In the present invention, there is a gap between the lower conductor and the upper conductor, so when induced electricity is generated, a potential difference will be generated between the lower conductor and the upper conductor, and the lower conductor and the upper conductor form a closed circuit, so current will be generated between the upper conductor and the lower conductor.

[0024] (8) When the light-emitting structure of the present invention emits light, the light will propagate along the optical fiber, so that the optical fiber as a whole emits light. When the optical fiber emits light, the light will overflow through the transparent outer cladding, thereby achieving the purpose of making the light strip emit light.

[0025] (9) The present invention abandons plastic materials, effectively improving the environmental friendliness of the product.

[0040] Example 1

[0041] like Figure 1 As shown, an environmentally friendly light-emitting cable includes an inner core portion 100 , an outer package portion 200 wrapped around the outer side of the inner core portion 100 , and a light-emitting portion 300 arranged outside the outer package portion 200 .

[0042] By setting up the light-emitting part, the staff can judge whether the cable has generated induced electricity by the light of the light-emitting part, which can help the staff to quickly eliminate safety hazards, better improve the safety of product use, reduce the difficulty of troubleshooting and maintenance, improve the efficiency of troubleshooting and maintenance, and better reduce the labor cost required for the later maintenance of the product.

[0043] like Figure 2 As shown, the inner core part 100 is composed of an elastic inner core 101, a copper wire arranged outside the elastic inner core 101, and a shielding layer 107 arranged outside the copper wire; the copper wire is composed of a copper core 102, and a copper core insulation layer 103 wrapped around the outside of the copper core 102.

[0044] The elastic inner core is made of hemp rope, which can reduce the cost of the product and effectively improve the flexibility of the cable.

[0045] The angles between any two adjacent copper wires are the same, and a support sheet 104 is provided between any two adjacent copper wires.

[0046] The copper core insulation layer and support sheet are both made of TPE material. The support sheet can effectively support the copper wire, which can effectively prevent the copper wire from being dislocated due to external force during transportation or use, better ensure the spacing between the copper wires, and improve the safety of product use.

[0047] An inner filling layer 105 is disposed between the support sheet 104 and the elastic inner core 101 , and an outer filling layer 106 is disposed between the shielding layer and the support sheet 104 .

[0048] The inner filling layer is filled with glass fiber yarn, which has good insulation and heat resistance, and better improves the safety of product use. At the same time, the glass fiber yarn also has good mechanical strength, which can better improve the cable's resistance to external forces, thereby better preventing the cable from being deformed by external forces.

[0049] The outer filling layer is filled with aramid yarn, which has excellent properties such as high temperature resistance, acid resistance, alkali resistance, light weight, and extremely high strength. It can still protect the copper wire well when the outside of the cable is damaged, further improving the safety of the product.

[0050] The outer package 200 is composed of an inner PVC layer 201 wrapped outside the shielding layer 107 , an armor layer 202 wrapped outside the inner PVC layer 201 , a non-woven fabric layer 203 wrapped outside the armor layer 202 , and an outer PVC layer 204 wrapped outside the non-woven fabric layer 203 .

[0051] The inner PVC layer, the armor layer, the non-woven fabric layer and the outer PVC layer are all prior art, and those skilled in the art can complete their configuration without creative labor, so they will not be described in detail here.

[0052] like Figure 3-5 As shown, the light emitting portion 300 is composed of an outer insulating layer 301 , a light emitting bar 302 , an upper conductor 303 , a lower conductor 304 and a light emitting structure 305 arranged on the outer insulating layer 301 .

[0053] The outer insulating layer 301 is wrapped around the outer side of the outer PVC layer 204 .

[0054] The light bar 302 is wound around the outer wall of the outer insulating layer 301 , and the front end of the light bar 302 penetrates the outer insulating layer 301 ; the light bar 302 is embedded in the outer wall of the outer insulating layer 301 .

[0055] The winding length of the light strip can be adjusted according to the actual usage. In theory, the farther the cable is from the visible distance, the longer the winding length is. The purpose is to increase the visible area to facilitate observation by staff at a long distance.

[0056] The lower conductor 304 is spirally arranged on the inner wall of the outer insulating layer 301, the upper conductor 303 is arranged inside the outer insulating layer 301 along the axial direction of the outer insulating layer 301, and the two ends of the upper conductor 303 are respectively connected to the two ends of the lower conductor 304; the light-emitting structure 305 is connected in series between the upper conductor 303 and the lower conductor 304.

[0057] There is a gap between the lower conductor and the upper conductor, so when induced electricity is generated, a potential difference will be generated between the lower conductor and the upper conductor, and the lower conductor and the upper conductor form a closed circuit, so current will be generated between the upper conductor and the lower conductor.

[0058] The light-emitting structure can be selected according to the needs, and any electronic component that can emit light when a micro-current passes through it can be used as a light-emitting structure. In this application, the best choice for the light-emitting structure is a light-emitting diode. Depending on the use environment, components such as resistors can also be connected in series or in parallel with the light-emitting diode to ensure the safety of the light-emitting diode.

[0059] The light-emitting bar 302 is an optical fiber with a transparent outer cladding. The front end of the light-emitting bar 302 penetrates the outer insulating layer 301 and abuts against the light-emitting structure 305 .

[0060] When the light-emitting structure emits light, the light will propagate along the optical fiber, so that the optical fiber as a whole emits light. When the optical fiber emits light, the light will overflow through the transparent outer cladding, thereby achieving the purpose of making the light-emitting strip emit light.

[0061] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0062] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the present invention, and these solutions also belong to the disclosure scope of the present invention and fall within the protection scope of the present invention.
