Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable with good flexibility. Background Art

[0002] A cable is a wire used to transmit power and data. It is usually composed of a conductor and an insulating material. The conductor is usually made of metal, such as copper or aluminum. Cable conduit work is the process of installing cables to be bundled and protected. Before performing cable conduit work, some preparation work is required. First, the location and length of the conduit need to be determined to ensure that the cable can pass smoothly. Then, appropriate tools and materials, such as pliers and conduits, need to be used to install and fix the conduits. When installing the conduits, make sure that the cables are not twisted or damaged in any way. Next, the cables need to be inserted into the conduits. In the process of using traditional cables, it is necessary to determine the position and length of the threading tube when performing the threading tube operation, and ensure that the cable is not twisted or damaged in any way before inserting the cable into the threading tube. However, since traditional cables are generally made of copper wires, the copper wires will be deformed after bending and are difficult to recover, which affects the cable threading work. Utility Model Content

[0003] In order to overcome the problem in daily use of traditional cables, when threading the traditional cables through the conduit, it is necessary to determine the position and length of the conduit, and to ensure that the cable is not twisted or damaged in any way before inserting the cable into the conduit. However, since traditional cables are generally made of copper wires, the copper wires will be deformed after bending and are difficult to recover, which affects the cable threading work.

[0004] The technical solution of the utility model is: a cable with good flexibility, comprising a copper core, a shielding component, a protective component, a reset component, a protection component, an installation component and a filler; the copper core is provided with three groups, a shielding component with a shielding function is provided on the outside of the copper core, a protective component with a protective function is provided on the outside of the shielding component, a reset component with a reset function is provided on the outside of the protective component, a protective component with a protective function is provided on the outside of the reset component, an installation component is provided on the outside of the protection component, and a filler is provided on the inside of the protective component.

[0005] Preferably, the copper core is shielded from electric field protection by means of a shielding component, the shielding component is protected by means of a protective component, the inside of the protective component is filled with a filler, the cable is reset to a straight state after being bent by means of a reset component, the reset structure has a certain buffer space when the cable is bent by means of a cavity structure inside the protective component, the reset structure is protected, and the cable is protected against corrosion by means of an installation component.

[0006] Preferably, the shielding assembly includes a conductor shielding layer and an insulating layer; the conductor shielding layer is arranged on the outside of the copper core, and the insulating layer is arranged on the outside of the conductor shielding layer. When in use, the copper core is shielded by the conductor shielding layer for electric field protection, and the copper core is insulated by the insulating layer for protection.

[0007] Preferably, the protective component includes a metal shielding layer and an inner sheath; the metal shielding layer is arranged on the outside of the insulating layer, and the inner sheath is arranged on the outside of the metal shielding layer. When in use, the insulating layer is shielded and protected by the metal shielding layer, and the multiple groups of copper cores inside the inner sheath are protected by the inner sheath.

[0008] Preferably, the reset component includes a first steel belt armor and a spring; the first steel belt armor is arranged on the outer side of the inner sheath, and the spring is arranged on the outer side of the first steel belt armor. When in use, the inner sheath and the spring are separated by the first steel belt armor. When the cable is bent, the spring is deformed and stores elastic potential energy. When the external force disappears, the elastic potential energy will be released, so that the spring returns to its original shape, and the shape of the cable is restored, preventing the copper core of the cable from being deformed and difficult to return to its original shape after being bent, resulting in poor flexibility of the copper core cable when the cable is threaded through the pipeline, affecting the normal threading operation of the cable.

[0009] Preferably, the reset component also includes a second steel belt armor; the second steel belt armor is arranged on the outside of the spring. When in use, the spring is protected by the second steel belt armor to prevent rubber particles in the cable from falling into the spring and affecting the reset characteristics of the spring.

[0010] Preferably, the protection component includes an outer sheath and a buffer cavity; the outer sheath is arranged on the outer side of the second steel belt armor, and the buffer cavity is opened on the inner side of the outer sheath. When in use, the buffer cavity inside the outer sheath can provide a certain buffer space for the spring to be squeezed after being twisted when the cable is bent, thereby preventing the spring from lacking buffer space when the cable is bent, resulting in damage to the spring and affecting the flexibility of the cable.

[0011] Preferably, the installation assembly includes a rubber shell and a corrosion-resistant layer; the rubber shell is arranged on the outside of the outer sheath, and the corrosion-resistant layer is arranged on the outside of the rubber shell. When in use, the outer sheath is protected by the rubber shell, and the corrosion resistance of the rubber shell is improved by the corrosion-resistant layer, so that the cable is protected against corrosion, the speed at which the cable is corroded is reduced, and the service life of the cable is increased.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional cable, when threading the tube, it is necessary to determine the position and length of the tube, and ensure that the cable is not twisted or damaged before inserting the cable into the tube. However, since the traditional cable is generally made of copper wire, the copper wire will be deformed after bending and it is difficult to recover, which affects the cable threading work. The cable uses a metal protective layer to prevent impurities from affecting the reset structure. The cable can be quickly reset after bending by elastic reset, and the reset structure is buffered and protected, thereby improving the flexibility of the cable, so that the cable can be more smoothly threaded in the tube;

[0014] 2. The inner sheath and the spring are separated by the first steel belt armor. When the cable is bent, the spring is deformed and stores elastic potential energy. When the external force disappears, the elastic potential energy will be released, so that the spring returns to its original shape, and the shape of the cable is restored, so as to prevent the copper core of the cable from being deformed and difficult to return to the original shape after being bent, resulting in poor flexibility of the copper core cable during the pipeline threading work of the cable, affecting the normal threading operation of the cable. The spring is protected by the second steel belt armor to prevent the rubber material particles in the cable from falling into the spring and affecting the reset characteristics of the spring. The buffer cavity inside the outer sheath can have a certain buffer space when the spring is twisted and squeezed when the cable is bent, so as to prevent the spring from lacking buffer space when the cable is bent, resulting in damage to the spring and affecting the flexibility of the cable, thereby improving the flexibility of the cable and making the cable more smoothly when threading the cable through the pipeline;

[0015] 3. The outer sheath is protected by a rubber shell, and the corrosion resistance of the rubber shell is improved by a corrosion-resistant layer, so that the cable is protected against corrosion, the speed at which the cable is corroded is reduced, and the service life of the cable is increased.

When in use, the inner sheath 302 and the spring 402 are separated by the first steel belt armor 401. When the cable is bent, the spring 402 is deformed and stores elastic potential energy. When the external force disappears, the elastic potential energy will be released, so that the spring 402 returns to its original shape, and the shape of the cable is restored, preventing the copper core 1 of the cable from being deformed and difficult to return to the original shape after being bent, resulting in poor flexibility of the copper core 1 cable during pipeline threading of the cable, affecting the normal cable threading operation.

When the cable is bent, the spring 402 is deformed and stores elastic potential energy. When the external force disappears, the elastic potential energy will be released, so that the spring 402 returns to its original shape, and the shape of the cable is restored, so as to prevent the copper core 1 of the cable from being deformed and difficult to return to the original shape after being bent, resulting in poor flexibility of the copper core 1 cable during pipeline threading of the cable, affecting the normal threading operation of the cable. The spring 402 is protected by the second steel belt armor 403 to prevent the rubber material particles in the cable from falling into the spring 402 and affecting the reset characteristics of the spring 402.
