This patent application claims the benefit and priority of Chinese Patent Application No. 2023109216458 filed with the China National Intellectual Property Administration on Jul. 26, 2021, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.
The present disclosure relates to the technical field of cables, in particular to an auxiliary wire including a loose jacket protective structure, a flat cable and a round cable.
The electric shovel tail wires and electric drill tail wires in open-pit coal mines, or cables of coal miners in underground coal mines, or reel cables and towing cables used in port machinery and other equipment are not fixed in laying and using process, but the cables need to move. In the process of movement of the cables, the cables are repeatedly subjected to tensile force, torsion, bending, lateral pressure or external force impact. These factors cause the auxiliary wire such as a control wire, a communication wire and an optical fiber in the cable to be easily broken or damaged, so that the whole cable is out of action and scrapped. The reason that the auxiliary wire such as a control wire, a communication wire and an optical fiber is easy to be damaged is that the auxiliary wires are often very thin compared with power wires in the cables. For example, the cross-sectional area of the power wire is 185 mm2, but the cross-sectional area of the control wire is only 4 mm2. The cross-sectional area of the communication wire may be only 0.5 mm2, and the diameter of the optical fiber is naturally smaller. So the tensile capacity of these auxiliary wires is poor. If there are no special protective measures, these auxiliary wires are often damaged quickly in the using process of the cable, so that the service life of the cable is seriously influenced.
The purpose of the present disclosure is to provide an auxiliary wire including a loose jacket protective layer, a flat cable and a round cable. The loose jacket protective layer can effectively protect the auxiliary wire such as a control wire, a communication wire and an optical fiber and prolong the service life of the auxiliary wire, so that the problem that an existing auxiliary wire is often damaged quickly to seriously affect the service life of the cable is solved.

Compared with the prior art, some embodiments have the following technical effects.
According to the auxiliary wire provided by some embodiments, by sleeving a loose jacket protective layer outside an auxiliary wire core, the purpose of protecting the auxiliary wire is achieved, and the durable time of the auxiliary wire is greatly prolonged, so that the service life of the cable is greatly prolonged, and the economic benefits of users are improved. At the same time, because the service life of the cable is prolonged, the production capacity of the cable can be reduced, and the consumption of electrolytic copper and polymer materials is reduced. Copper is smelted by electrolysis that consumes a lot of electric energy, and polymer materials basically come from non-renewable fossil energy sources such as petroleum, coal and natural gas. Therefore, by prolonging the service life of the cable, intuitive economic benefits can be brought to users, energy conservation and environmental protection are facilitated, and thus contributions are made to low-carbon and green economy.
In the flat cable and the round cable provided by the present disclosure, are each provided with the auxiliary wire with the loose jacket protective layer, so that the service life of the cable is greatly prolonged, and then the economic benefits of users are improved.
To more clearly illustrate the present embodiment of the present disclosure or the technical scheme in the prior art, the following briefly introduces the drawings to be used in the present embodiment. Apparently, the drawings in the following description show merely some embodiments of the present disclosure, and those skilled in the art may still derive other drawings from these drawings without creative efforts.
The following clearly and completely describes the technical scheme in the embodiments of the present disclosure with reference to the embodiments of the present disclosure. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. Based on the embodiment in the present disclosure, all other embodiments obtained by the ordinary technical staff in the art under the premise of without contributing creative labor belong to the scope protected by the present disclosure.
One of the purposes of the present disclosure is to provide an auxiliary wire including a loose jacket protective layer. The loose jacket protective layer can effectively protect the auxiliary wire such as a control wire, a communication wire and an optical fiber and prolong the service life of the auxiliary wire, so that the problem that an existing auxiliary wire is often damaged quickly to seriously affect the service life of the cable is solved.
Another purpose of the present disclosure is to further provide a flat cable with the auxiliary wire.
Then, a further purpose of the present disclosure is to further provide a round cable with the auxiliary wire.
To make the above-mentioned purposes, features and advantages of the present disclosure apparent and understandable, the present disclosure is further described in detail below with reference to the drawings and specific embodiments.
As shown in
In the scheme, the auxiliary wire core 11 of the auxiliary wire is arranged in a special loose jacket protective layer 12 to play a role in protecting a thinner auxiliary wire core in the cable, so that the thinner wire core in the cable is higher in durability in the mobile application of cables and is beneficial to long-term use without easy damage, so that the service life of the wire core is prolonged, the service life of the cable is also prolonged, and the economic benefits are improved. The thinner core of the cable is the auxiliary wire core 11, and specifically can be a control wire, a communication wire, a single wire core or a multi-core combined wire core. The thinner wire core is characterized in that the cross-sectional area of the wire core is generally less than 10 mm2 or the wire core is an optical fiber unit. “Mobile application of cables” means that cables are constantly moving or traveling in use, instead of being fixedly laid. For example, the cable may be a coal cutter cable, an open-pit shovel tail cable and other cables. Some cables, such as reel cables on port machinery equipment, need to be wound in reels and continuously taken in and out. Some cables, such as towing cables, need to be erected in towing racks and move with cable hooks.
In the embodiment, the auxiliary wire further includes an outer protective layer 13 of polymer material sleeving the outside of the loose jacket protective layer 12. The outer protective layer 13 may be of a single-layer structure or a double-layer structure, the material of the outer protective layer 13 may be rubber (such as ethylene propylene rubber, chloroprene rubber or chlorinated polyethylene rubber), an elastomer, and other suitable polymer materials, and the colors thereof may be black, full colors, translucent colors, and transparent colors. Generally, the outer protective layer 13 may or may not be provided according to the design requirements.
In the embodiment, the auxiliary wire further includes a shielding layer 14 sleeving the outermost layer of the loose jacket protective layer 12. In the scheme, when the outer protective layer 13 does not sleeve the outside of the loose jacket protective layer 12, the outermost layer of the loose jacket protective layer 12 is an outer layer of the loose jacket protective layer 12, and the shielding layer 14 directly sleeves the outside of the loose jacket protective layer 12. When the outer protective layer 13 sleeves the outside of the loose jacket protective layer 12, the outermost layer of the loose jacket protective layer 12 is the outer layer of the outer protective layer 13, and the shielding layer 14 sleeves the outside of the outer protective layer 13. The shielding layer 14 may or may not be provided according to actual requirements. When the shielding layer 14 is provided, the shielding layer 14 may be a metal wire braided shielding layer, a metal wire/fiber braided shielding layer, or a metal wire wound shielding layer. When the auxiliary wire 1 is applied to cable, the outermost layer is generally provided with a shielding layer 14.
In the embodiment, the auxiliary wire 1 specifically can be a control wire, a communication wire or an optical fiber. In general, when the auxiliary wire 1 is a control wire or a communication wire, any wire core includes a wire core conductor 111 and a wire core insulating layer 112 sleeving the outside of the wire core conductor 111. When the auxiliary wire 1 is an optical fiber, any wire core includes an optical fiber core and an optical fiber sleeve 15 sleeving the outside of the optical fiber core. When multiple optical fiber sleeves 15 are provided, the optical fiber sleeves 15 are twisted to form an auxiliary wire core 11. The wire core arrangement of the control wire, the communication wire and the optical fiber are all related to the prior art, and are not be described here.
The auxiliary wire 1 can be applied to existing cables. The cable core can only include the auxiliary wire 1, or besides auxiliary wire 1, a power wire core, a ground wire core and a grounding detection wire core are further arranged. Generally, it is necessary to select the composition and structure of cable core according to the cable installation and laying conditions. According to different application occasions and environments, the cable can be of a round structure, a flat structure or other special-shaped structures. In the round cable, the wire cores are twisted into a cable core. In the flat cable, the wire cores are arranged in parallel. No matter which kind of form, the outer side of the wire core is coated with an outer sheath of the cable.
It can be seen that in the scheme, the service life of an originally non-durable auxiliary wire is prolonged by providing a special protection structure, that is, the loose jacket protective layer 12, for the auxiliary wire. So that the service life of the cable is prolonged as a whole, direct economic benefits are brought to users, and real contributions are made to the green and low-carbon economy.
In practical application, preferably, the loose jacket protective layer 12 is formed by tube extrusion of polymer materials with a certain hardness. Compared with a steel wire winding process, the process of the tube extrusion of polymer materials is more mature, the production speed of the tube extrusion of polymer materials is higher, the weight of the loose jacket protective layer 12 is lighter, and the lightweight of cables is realized more easily.
The embodiment provides a flat cable 100. The flat cable 100 includes a flat cable sheath 2, a power wire core 3 and an auxiliary wire 1 disclosed in the first embodiment. The power wire core 3 and the auxiliary wire 1 are both embedded in the flat cable sheath 2, and the power wire core 3 and the auxiliary wire 1 are arranged in parallel along the width direction of the flat cable sheath 2. The flat cable sheath 2 is made of conventional cable sheath materials, and the cross section thereof is non-circular and flat. For example, the profile of the cross section of the flat cable sheath 2 is a rectangular profile or an elliptical profile. The flat structure of the flat cable 100 is beneficial to reduce the outer diameter of the cable. Compared with a common round cable, the bending radius of the flat cable can be reduced by ½, and the flat cable cannot be distorted during moving, so that the service life of the flat cable is prolonged.

In the flat cable 100 of the scheme, the inner wire cores are arranged in parallel side by side, and the outer diameter of the cable is reduced, which is suitable for use occasions with narrow space. Compared with the round cable, the bending radius of the flat cable can be reduced by ½. At the same time, the flat cable cannot be distorted even in the moving process after being installed and laid, so that the problem that the wire core of the cable is broken due to the distortion of the cable is avoided, and the cable has a longer service life.
