Description

Technical Field

[0001] This utility model belongs to the field of cables, specifically, it relates to an anti-slip and wear-resistant cable. Background Technology

[0002] A cable is an electrical device used to transmit electrical energy, signals, or data. It is typically made up of one or more insulated conductors twisted together and encased in a protective sheath.

[0003] Chinese patent application CN202222778712.9 discloses an anti-slip and wear-resistant wire and cable, including an outer protective sleeve. Anti-slip rings are uniformly fixedly connected to the outer surface of the outer protective sleeve, and steel wire armor is uniformly fixedly connected to the inside of the outer protective sleeve. In this invention, by setting anti-slip rings on the outer protective sleeve of the optical cable, the anti-slip rings increase the surface roughness of the outer protective sleeve, making the outer surface of the outer protective sleeve concave and convex. Furthermore, anti-slip textures are formed on the outer surface of the anti-slip rings. These textures increase the friction between the worker's hand and the outer surface of the optical cable when gripping it, making the worker more stable when pulling and gripping the optical cable and preventing it from slipping from their hand. Additionally, anti-wear protrusions are provided on the outer surface of the outer protective sleeve. These anti-wear protrusions can replace the anti-slip rings in contact with the ground when the optical cable moves, preventing the anti-slip rings from wearing down and losing their anti-slip function due to friction with the ground during movement.

[0004] However, the stress of the aforementioned existing technology is concentrated on the cable surface when bent, which can easily cause cable damage. At the same time, the outer side of the cable cannot be quickly replaced after wear, and it cannot meet the needs of emergency maintenance.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a non-slip and wear-resistant cable.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A non-slip and wear-resistant cable includes a connecting core and a copper core conductor. The connecting core has three fixed openings inside, and the copper core conductor is fixedly installed inside the fixed openings. A spiral buffer assembly is fixedly installed on the outside of the connecting core. An insulation layer is hot-pressed to the outside of the spiral buffer assembly. A water-blocking layer is hot-pressed to the outside of the insulation layer. An inner protective sleeve is adhesively fixed to the outside of the water-blocking layer. A steel wire armor is fixed to the outside of the inner protective sleeve. An outer protective sleeve is fixed to the outside of the steel wire armor. An annular groove is provided on the outside of the outer protective sleeve, and a detachable non-slip component is fixedly installed inside the annular groove.

[0009] Optionally, the wire armor is located between the inner protective sleeve and the outer protective sleeve.

[0010] Optionally, the spiral buffer assembly includes a first spiral elastic buffer layer, the inner side of which is wound and fixedly installed on the outer side of the connecting core.

[0011] Optionally, a fixing layer is fixed to the outside of the first spiral elastic buffer layer, and a second spiral elastic buffer layer is wound and fixed to the outside of the fixing layer.

[0012] Optionally, the detachable anti-slip component includes a fixing bracket that engages with the annular groove.

[0013] Optionally, a fixing bolt is fixedly installed between the two fixing brackets located inside the same annular slot.

[0014] Optionally, anti-wear protrusions are fixed to the outside of the fixing frame, and an anti-slip plate is fixed between the two anti-wear protrusions.

[0015] Optionally, the bottom of the anti-slip plate contacts the outer side of the outer protective cover, and the top of the anti-slip plate is fixed with anti-slip protrusions.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0017] This invention utilizes a spiral buffer assembly to provide multiple buffers for the connecting core and copper core conductor, preventing them from being directly subjected to excessive stress, avoiding deformation and breakage of the copper core conductor, and extending the cable's service life. Furthermore, the spiral winding design reduces stress concentration during cable bending, enhancing the cable's compressive strength. Simultaneously, the detachable anti-slip assembly improves the cable's anti-slip and wear-resistant properties, allowing for quick replacement after wear without interrupting cable operation, thus meeting emergency maintenance needs.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this embodiment provides an anti-slip and wear-resistant cable, including a connecting core 1 and a copper core conductor 2. The connecting core 1 has three fixed openings inside. The connecting core 1 is made of high-density polyethylene material. The copper core conductor 2 is fixedly installed inside the fixed openings. The copper core conductor 2 is made of multiple strands of tin-plated copper wire twisted together. Its outer diameter is fitted with the gap of the fixed opening and is fixed by hot melt adhesive to ensure the stability of the electrical connection. A spiral buffer assembly 3 is fixedly installed on the outside of the connecting core 1. An insulation layer 4 is hot-pressed and fixed on the outside of the spiral buffer assembly 3. A water-blocking layer 5 is hot-pressed and fixed on the outside of the insulation layer 4. An inner protective sleeve 6 is glued and fixed on the outside of the water-blocking layer 5. A steel wire armor 7 is fixed on the outside of the inner protective sleeve 6. An outer protective sleeve 8 is fixed on the outside of the steel wire armor 7. An annular groove is provided on the outside of the outer protective sleeve 8 to facilitate quick disassembly and assembly of the detachable anti-slip assembly 9 without interrupting cable operation, which can meet the needs of emergency maintenance. The detachable anti-slip assembly 9 is fixedly installed inside the annular groove. The steel wire armor 7 is located between the inner protective sleeve 6 and the outer protective sleeve 8.

[0029] One application of this embodiment is as follows: a spiral buffer assembly 3, an insulation layer 4, a water-blocking layer 5, an inner protective sleeve 6, a steel wire armor 7, and an outer protective sleeve 8 are sequentially heat-pressed onto the outside of the connecting core 1. The spiral buffer assembly 3 provides multiple buffering effects for the connecting core 1 and the copper core conductor 2, preventing the connecting core 1 and the copper core conductor 2 from being subjected to excessive stress directly, thus extending the service life of the cable. The insulation layer 4 can isolate the conductor in the cable from the outside world, preventing current leakage to the outside, avoiding unnecessary loss of electrical energy, ensuring that power can be transmitted efficiently and stably in the conductor, reducing energy loss during transmission, improving power transmission efficiency, and the insulation layer 4 can also play a certain shielding role, reducing the interference of the electromagnetic field generated by the current inside the cable to other electronic devices in the surrounding environment, and at the same time preventing the cable from short-circuiting due to contact with external objects, thus preventing safety accidents such as fires.

[0030] The water-blocking layer 5 can effectively prevent moisture from entering the cable interior, avoiding damage to the cable insulation layer 4 and copper core conductor 2. At the same time, the inner protective sleeve 6 and the outer protective sleeve 8 improve the protection effect of the cable. The steel wire armor 7 improves the cable's tensile, compressive and impact resistance. Together with the inner protective sleeve 6 and the outer protective sleeve 8, it ensures that the internal structure and insulation performance of the cable are not affected. In addition, the steel wire armor 7 can act as a physical barrier to prevent small animals such as rats and insects from damaging the cable.

[0031] The spiral buffer assembly 3 includes a first spiral elastic buffer layer 301, which is wound and fixedly installed on the outside of the connecting core 1. A fixing layer 302 is fixed on the outside of the first spiral elastic buffer layer 301. The fixing layer 302 can connect the first spiral elastic buffer layer and the second spiral elastic buffer layer 303 together. The second spiral elastic buffer layer 303 is wound and fixed on the outside of the fixing layer 302.

[0032] In this embodiment, the first spiral elastic buffer layer 301 and the second spiral elastic buffer layer 303 can provide multiple buffers for the connecting core 1 and the copper core conductor 2, preventing the connecting core 1 and the copper core conductor 2 from being directly subjected to excessive stress, thereby avoiding deformation and breakage of the copper core conductor 2 and extending the service life of the cable.

[0033] In this embodiment, the first spiral elastic buffer layer 301 is wound clockwise, and the second spiral elastic buffer layer 303 is wound counterclockwise. The first spiral elastic buffer layer 301 and the second spiral elastic buffer layer 303 form a cross buffer structure, which can disperse axial and radial stress.

[0034] The detachable anti-slip component 9 includes a fixing bracket 901, which is snapped into the annular groove. A fixing bolt 902 is fixedly installed between two fixing brackets 901 located in the same annular groove. An anti-wear protrusion 903 is fixed to the outside of the fixing bracket 901. The anti-wear protrusion 903 replaces the outer protective sleeve 8 and contacts the ground, thereby improving the wear resistance of the cable. An anti-slip plate 904 is fixed between the two anti-wear protrusions 903. The bottom of the anti-slip plate 904 contacts the outside of the outer protective sleeve 8, and an anti-slip protrusion 905 is fixed to the top of the anti-slip plate 904.

[0035] In this embodiment, two fixing brackets 901 are placed manually inside the same annular slot, and the two fixing brackets 901 are fixed with fixing bolts 902, which allows for quick installation of the anti-wear protrusions 903 and anti-slip plates 904. The anti-wear protrusions 903, anti-slip plates 904 and anti-slip protrusions 905 all improve the anti-slip and wear-resistant effect of the cable, extend the service life of the cable, and facilitate the operation of the laying personnel.
