Description

Technical Field

[0001] The utility model relates to the technical field of cables, and particularly relates to a cable which is convenient for detection and maintenance. Background Art

[0002] A cable is an electrical product used for transmitting electric energy, signals or realizing the conversion of electromagnetic energy, and is widely used in many fields such as electric power, communication, construction, transportation, industrial control and the like.

[0003] During the use of the cable, due to the long-term action of external forces such as friction and bending, the outer skin of the cable will gradually wear until the internal conductor is exposed, which not only affects the insulation performance of the cable, but also may cause safety hazards such as short circuit and electric leakage. However, the existing cables often lack intuitive wear indication, making it difficult for users to timely discover and replace severely worn cables. Therefore, a cable which is convenient for detection and maintenance is proposed to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a cable which is convenient for detection and maintenance to overcome the deficiencies in the above prior art.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A cable which is convenient for detection and maintenance includes two copper wires. Insulating rubber skins are fixedly installed outside both of the two copper wires. A connecting sleeve is fixedly installed outside both of the insulating rubber skins. A plurality of steel wires are fixedly installed inside the connecting sleeve. An inner protective layer is fixedly installed outside the connecting sleeve. An outer protective layer is fixedly installed outside the inner protective layer. The outer colors of the connecting sleeve, the inner protective layer and the outer protective layer are different from each other and have obvious color differences.

[0006] The beneficial effect of the utility model is that: The two insulating rubber skins isolate and protect the two copper wires. The plurality of steel wires strengthen the strength of the cable and prevent the cable from being torn off. When the outer protective layer is damaged, the inner protective layer will be exposed. Since the outer colors of the connecting sleeve, the inner protective layer and the outer protective layer are different from each other and have obvious color differences, it is greatly convenient for users to timely discover the wear degree.

[0007] On the basis of the above technical solution, the utility model can also be improved as follows.

[0008] Further, a connection cylinder is fixedly installed on the outside of the outer protective layer near its top. An internal thread cylinder is fixedly installed at the top of the connection cylinder. The connection cylinder is sleeved outside two insulating rubber sheets. An external thread cylinder is slidably installed on the outside of the outer protective layer near its bottom. A first retaining ring located inside the external thread cylinder is fixedly installed on the outside of the outer protective layer. Cylindrical plugs are fixedly installed at the bottoms of both copper wires outside the outer protective layer.

[0009] Further, a second retaining ring is fixedly installed on the outside of the outer protective layer, and the second retaining ring is located at the top of the external thread cylinder.

[0010] Further, the distance between the two insulating rubber sheets is not less than 0.7 cm.

[0011] Further, multiple steel wires are all located outside the two insulating rubber sheets, and the multiple steel wires are circumferentially and regularly distributed inside the connecting sleeve.

[0020] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0021] Embodiment 1. A cable facilitating detection and maintenance includes two copper wires 1. Insulating rubber sheets 2 are fixedly installed on the outsides of the two copper wires 1. A connecting sleeve 3 is fixedly installed on the outsides of the two insulating rubber sheets 2. A plurality of steel wires 4 are fixedly installed inside the connecting sleeve 3. An inner protective layer 5 is fixedly installed on the outside of the connecting sleeve 3. An outer protective layer 6 is fixedly installed on the outside of the inner protective layer 5. The outside colors of the connecting sleeve 3, the inner protective layer 5, and the outer protective layer 6 are different from each other and have obvious color differences. The overall color of the outer protective layer 6 is black, the overall color of the inner protective layer 5 is white, and the overall color of the connecting sleeve 2 is orange.

[0022] The two insulating rubber sheets 2 isolate and protect the outsides of the two copper wires 1. The installed connecting sleeve 3 can connect the two insulating rubber sheets 2 and the copper wires 1 together. At this time, the plurality of steel wires 4 strengthen the strength of the cable and prevent the cable from being torn off. Subsequently, the installed inner protective layer 5 can protect the outside of the connecting sleeve 3, and the outer protective layer 6 protects the outside of the inner protective layer 5. When the outer protective layer 6 is damaged, the inner protective layer 5 will be exposed. Since the color of the inner protective layer 5 is white, it will form a strong contrast with the outer protective layer 6, thus facilitating users to timely discover the degree of wear. When orange is observed, it means that the cable urgently needs to be replaced.

[0023] Embodiment 2. This embodiment is a further improvement based on Embodiment 1, and the specific details are as follows:

[0024] A connecting cylinder 7 is fixedly installed on the outside of the outer protective layer 6 near its top. An internal thread cylinder 701 is fixedly installed at the top of the connecting cylinder 7. The connecting cylinder 7 is sleeved on the outsides of the two insulating rubber sheets 2. An external thread cylinder 8 is slidably installed on the outside of the outer protective layer 6 near its bottom. A first retaining ring 9 is fixedly installed on the outside of the outer protective layer 6 and located inside the external thread cylinder 8. Cylindrical plugs 10 are fixedly installed at the bottoms of the two copper wires 1 and located outside the outer protective layer 6.

[0025] When two cables need to be installed, first put two cylindrical plugs 10 on the outside of two copper wires 1. Then slide the external thread cylinder 8 downward and thread it onto the internal thread cylinder 701 at the top of the connecting cylinder 7. At the same time, the connection between the external thread cylinder 8 and the internal thread cylinder 701 is equipped with corresponding sealing rings to prevent water from entering the inside of the connecting cylinder 7. The first retaining ring 9 installed on the outside of the external protective layer 6 can limit the external thread cylinder 8 and also seal the connection between the external thread cylinder 8 and the external protective layer 6, thereby preventing the external thread cylinder 8 from detaching from the outside of the external protective layer 6. At this time, the two cables are quickly installed together. When cable maintenance or replacement is needed, directly rotate the external thread cylinder 8 in the reverse direction to disconnect it from the internal thread cylinder 701, and then the two connected cables can be easily pulled out.

[0026] Embodiment 3 is a further improvement based on Embodiment 1, and the specific content is as follows:

[0027] A second retaining ring 11 is fixedly installed on the outside of the external protective layer 6, and the second retaining ring 11 is located at the top of the external thread cylinder 8.

[0028] The top of the external thread cylinder 8 is restricted by the installed second retaining ring 11 to prevent the external thread cylinder 8 from sliding towards the top of the copper wire 1.

[0029] Embodiment 4 is a further improvement based on Embodiment 1, and the specific content is as follows:

[0030] The distance between the two insulating rubbers 2 is not less than 0.7 cm.

[0031] Prevent electromagnetic interference between the two copper wires 1.

[0032] Embodiment 5 is a further improvement based on Embodiment 1, and the specific content is as follows:

[0033] Multiple steel wires 4 are all located outside the two insulating rubbers 2, and the multiple steel wires 4 are evenly distributed in a circular arrangement inside the connecting sleeve 3.

[0034] The outside of the two copper wires 1 and the insulating rubbers 2 is stably protected by multiple steel wires 4 to reduce the tensile blind area.

[0035] Embodiment 6 is a further improvement based on Embodiment 1, and the specific content is as follows:

[0036] The inner diameter of the cylindrical plug 10 is larger than the diameter of the copper wire 1, which is convenient for the cylindrical plug 10 to be put on the outside of the copper wire 1.

[0037] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present utility model.
