Description

Technical Field

[0001] The invention relates to the technical field related to cables, and in particular to a wear-resistant and moisture-proof cable. Background Art

[0002] Cable is a collection of conductors used to transmit electrical energy or signals. In order to increase the service life of the cable, a protective structure needs to be set on the outside of it. However, the existing wear-resistant and moisture-proof cables still have certain defects when used, such as; During use, the single inner core of the existing cable has a low current carrying capacity and cannot meet the needs of high-power equipment. In addition, the single inner core is easily damaged or broken, which increases the overall maintenance and replacement costs and limits the flexibility and diversity of use. In order to overcome the above-mentioned defects, prior art 1 (Chinese patent with application number CN201010214074.7 and application date 2010-06-24) is a cable that reduces the contact between strands and greatly reduces the wear and breakage caused by cable bending. The cable is provided with an insulating layer, a shielding layer, a reinforcing braided layer and a sleeve in sequence from the inside on the outer periphery of the multiple strands of the stranded wire. The reinforcing braided layer arranged between the shielding layer and the sleeve is a fiber braided layer with impact absorption. In addition, there is no limitation on the presence or absence of a shielding layer and a reinforcing braided layer. The multiple strands of the stranded wire are arranged in a roughly circular shape and are formed by twisting multiple conductor wires; and an inclusion is arranged in the approximate center of the stranded wire arranged in a roughly circular shape, and a spiral groove having a partition wall that separates adjacent strands of the multiple strands from each other and does not contact each other is formed on the inclusion and corresponds to each strand of the multiple strands of the stranded wire, and the groove matches at least a portion of the outer surface of the multiple strands of the stranded wire; There is also prior art 2 (application number CN201711166379.3, Chinese patent application date 2017-11-21) cable, including a cable core and an insulating layer coated on the outside of the cable core, the shielding layer coated on the outside of the insulating layer and the cable core and the insulating layer form a cable core unit, and a titanium layer and a wear-resistant layer are provided outside the cable core unit. Titanium is a metal with a strong passivation tendency. It can quickly generate a stable oxidative protective film in the air and in an oxidizing or neutral aqueous solution. Even if the protective film is destroyed for some reason, it can quickly recover automatically. It has the characteristics of high temperature resistance, corrosion resistance, wear resistance, and light weight. At the same time, because titanium is a metal, it also has the function of shielding electromagnetic interference. Therefore, the titanium layer can simultaneously realize multiple functions such as the high temperature layer, shielding layer, armor layer, and corrosion-resistant layer in ordinary cables, and titanium itself is lighter than ordinary metals of the same volume, thereby greatly simplifying the number of cable layers, structure, and process, while having at least the same or even better performance as existing cables, and greatly simplifying the structure and production process of the cable as a whole, while ensuring the performance of the cable, effectively reducing the weight of the cable and reducing the diameter of the cable; And prior art 3 (Chinese patent with application number CN202110394005.7 and application date 2021-04-13) is a cable, in which even if it is repeatedly bent, the multiple metal wires constituting the braided shielding member are not prone to breakage. The cable comprises: a cable core having one or more electric wires, a braided shielding member arranged in a manner covering the periphery of the cable core and braided by braiding the metal wires, and a sheath arranged in a manner covering the periphery of the braided shielding member, wherein a buffer layer is provided between the cable core and the braided shielding member, and the buffer layer is formed by a braided fabric formed by braiding linear fiber filaments.

[0003] Although the existing technology can improve the current carrying capacity, during the operation, multiple cable cores are set to transmit electric energy. However, the multiple cable cores are easily squeezed and the distance between them is too close, which not only increases the risk of short circuit, but also the friction generated by the multiple cable cores will cause damage and aging of the cables, shortening the service life of the cables. Moreover, after the multiple cable cores are moved, it is not only inconvenient to carry out installation and wiring operations, but also may cause signal crosstalk, affecting the transmission quality.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original wear-resistant and moisture-proof cable. Therefore, we proposed that the wear-resistant and moisture-proof cable can solve the above problems well. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

Figure 1-Figure 6The technical solution shown includes a cable inner core, a support seat 7 and a cable outer core. The cable inner core is arranged in an annular shape. The outer side of the cable inner core is connected to the cable outer core through the support seat 7. A limiting component is installed on the support seat 7. The limiting component includes a first through groove 8 opened on the support seat 7. The first through groove 8 is adapted to the cable inner core. The first through groove 8 is symmetrically opened. A second through groove 9 is opened on the support seat 7. The second through groove 9 is adapted to the cable inner core. The support seat 7 is arranged in an annular shape. A storage groove 10 is opened at the side end of the support seat 7. A support block 11 is installed inside the storage groove 10. The cable inner core is limited by the cooperation of the first through groove 8 and the second through groove 9 of the limiting component. The cable inner core includes a wire 1. The outer side of the wire 1 is provided with a second through groove 9. A first-level component, the first-level component includes an insulating color strip 2 installed on the outside of the conductor 1, the insulating color strip 2 is made of mica, a shielding layer 3 is installed on the outside of the insulating color strip 2, the shielding layer 3 is made of alloy wire, an anti-bending layer 4 is arranged on the outside of the shielding layer 3, the anti-bending layer 4 is made of elastic rubber, a heat insulation layer 5 is arranged on the outside of the anti-bending layer 4, a protective layer 6 is installed on the outside of the heat insulation layer 5, and the protective layer 6 is made of polytetrafluoroethylene. The outer side of the cable inner core is protected by a support seat 7, and the cable inner core is restricted in the first through groove 8 and the second through groove 9 of the support seat 7, so that the cable inner core is limited, which not only reduces the short circuit problem caused by the close distance between the cable inner cores, but also reduces the damage and aging of the cable caused by friction between the cable inner cores. The problem of cable core movement caused by squeezing is solved by the storage groove 10 provided on the support seat 7, and the support block 11 is conveniently limited, so that the cable is buffered when it is squeezed, reducing the problem of cable core movement caused by squeezing, greatly improving the service life of the cable, and the cable core is limited by the support seat 7, making the overall installation fast and convenient, facilitating the later use of the cable, and reducing the problem of wiring inconvenience and signal crosstalk caused by the movement of the cable core. The cable core gathers the required wires 1 and attaches the insulating color strip 2 to the outer surface of the wire 1. Since the insulating color strip 2 is made of mica, the mica material has high insulation strength and arc resistance, which can effectively prevent internal discharge and improve the safety performance of the cable. Alloy wires are woven by a braiding machine to form a shielding layer 3. The alloy wire material not only shields the electromagnetic field within the insulating color strip 2 and plays a certain protective role, but also facilitates the later laying and reduces the crosstalk problem caused by the electric field between different conductors 1. The anti-bending layer 4 on the outside of the shielding layer 3 is made of elastic rubber material. The elastic rubber material reduces the problem of damage to the internal structure of the cable caused by external bending factors to prevent signal transmission. The heat insulation layer 5 on the outside of the anti-bending layer 4 prevents the high temperature in the external environment from affecting the inside of the cable. The protective layer 6 is made of polytetrafluoroethylene. The polytetrafluoroethylene material can form a sealing layer when a fire occurs to prevent oxygen from entering the inside of the cable, thereby performing fire prevention operations and greatly improving the overall service life.

The filling layer 14 is made of sound-proof cotton material. The sound-proof cotton material causes multiple reflections, refractions and scattering of sound wave energy through its pores and fiber structure, so that the sound wave energy is gradually converted into heat energy and absorbed, reducing the impact of noise when the cable is used. The moisture-proof layer 15 is made of acrylonitrile butadiene rubber material. The acrylonitrile butadiene rubber material has good waterproof performance, which reduces the problem of the external environment affecting the inner core of the cable. The wear-resistant protrusion 16 arranged on the outside of the moisture-proof layer 15 is made of fluororubber material. Fluorine rubber has good wear resistance, which reduces the inconvenience caused by wear on the outside of the cable. The outer core of the cable is peeled off on the surface of the inner core of the cable to facilitate the connection of the inner core of the cable through the connector 17, the inner core of the cable is inserted into the connector 17, and the nut 19 is used to rotate on the surface of the threaded column 18, so that the first clamping block 20 moves toward the side end of the second clamping block 21, so that the second clamping block 21 squeezes the threaded column 18, so that the inner core of the cable is limited inside the connector 17, which not only reduces the problem of complex connection causing overall inconvenience in operation, but also reduces the problem of reduced moisture-proof performance due to manual connection, and the surface of the connector 17 is convenient for adding labels or QR codes, which is easy to track and manage.

The overall cleaning operation is convenient for cleaning before the cable is installed. It can also be set on the cable, and the rotating fan 24 is driven to rotate by the wind in the external environment, so the overall structure can be adjusted according to the required degree.
