Description

Technical Field

[0001] This utility model relates to the field of power facility technology, and in particular to a cable with an anti-bending mechanism. Background Technology

[0002] A cable is an electrical or signal transmission device, typically composed of several or groups of conductors, and characterized by internal current conduction and external insulation. Cables can be used to transmit electrical (magnetic) energy and information, realizing the conversion of electromagnetic energy. They are widely used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater power transmission lines across rivers and seas. There are many types of cables, including power cables, control cables, compensating cables, shielded cables, and high-temperature cables. They consist of single or multiple conductors and insulation layers, used to connect circuits and electrical appliances.

[0003] Existing cables generally have limited bending resistance and are prone to mechanical damage due to excessive bending. Furthermore, due to resistance, cables generate significant heat during power transmission. Given their generally poor heat dissipation, prolonged power transmission can easily lead to overheating and affect usability. Therefore, there is an urgent need to develop a cable with sufficient bending resistance to prevent mechanical damage from excessive bending, excellent heat dissipation, and to prevent overheating, thus overcoming current shortcomings and meeting current needs. Utility Model Content

[0004] The purpose of this invention is to provide a cable with an anti-bending mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable with an anti-bending mechanism includes a protective sleeve, a conductive core, a filler, a metal foil wrapping, a metal armor layer, and an anti-over-bending mechanism. Multiple anti-over-bending mechanisms are installed on the outer side of the protective sleeve. Each anti-over-bending mechanism includes a reinforcing sleeve, a plug, a locking block, and a locking slot. Two reinforcing sleeves are provided, each made of engineering plastic. Multiple plugs are fixed to the inner side of each reinforcing sleeve. The protective sleeve has mounting grooves for securing the reinforcing sleeves and multiple insertion holes for plug insertion. Multiple locking blocks are fixed to one reinforcing sleeve, and multiple locking slots are provided to secure the locking blocks to the other reinforcing sleeve. The protective sleeve is made of ethylene propylene rubber and has multiple heat dissipation grooves in a honeycomb pattern. A metal armor layer made of steel wire is provided on the inner side of the protective sleeve, and a metal foil wrapping is provided on the inner side of the metal armor layer, with multiple conductive cores installed within the metal foil wrapping.

[0007] Preferably, the conductive core is made of copper or aluminum alloy.

[0008] Preferably, an inner semiconductive shielding layer is provided on the outer side of the conductive core, an insulating sleeve is provided on the outer side of the inner semiconductive shielding layer, and an outer semiconductive shielding layer is provided on the outer side of the insulating sleeve.

[0009] Preferably, both the inner and outer semiconductive shielding layers are made of conductive fiber composite materials.

[0010] Preferably, the protective sleeve is provided with a filler, which is made of a polypropylene layer.

[0011] The beneficial effects of this utility model are as follows: During use, the cable has an anti-over-bending mechanism arranged at intervals on the protective sleeve. Because the reinforcing sleeve is made of engineering plastic, it has high strength and poor deformation capacity. When the cable bends to the reinforcing sleeve, it is blocked, making it difficult for the cable near the reinforcing sleeve to bend, thereby controlling the maximum bending angle of the cable and preventing mechanical damage caused by excessive bending. In addition, the heat generated by the conductive core is transferred outward to the metal foil wrapping and metal armor layer. Both the metal foil wrapping and metal armor layer are made of metal and have good thermal conductivity. The heat is transferred to the protective sleeve through the metal armor layer. The protective sleeve is provided with multiple honeycomb-shaped heat dissipation grooves, which increase the surface area of ​​the protective sleeve, thereby increasing the contact area between the protective sleeve and the air and improving the heat dissipation effect. The inner and outer semi-conductive shielding layers reduce external electromagnetic interference. The metal armor layer also improves the impact and puncture resistance. In summary, this utility model has a certain degree of resistance to bending, preventing mechanical damage caused by excessive bending of the cable; good heat dissipation, preventing the cable from overheating; good electromagnetic interference resistance; and good impact and puncture resistance.

Multiple anti-over-bending mechanisms 6 are installed on the outer side of the protective sleeve 1. Each anti-over-bending mechanism 6 includes a reinforcing sleeve 601, a plug 602, a locking block 603, and a locking groove 604. There are two reinforcing sleeves 601, which are made of engineering plastic to give them good strength. Each reinforcing sleeve 601... Multiple insertion rods 602 are fixed on the inner side of each sleeve. The protective sleeve 1 has mounting grooves 102 for securing the reinforcing sleeve 601, and multiple insertion holes 103 for inserting the insertion rods 602. One reinforcing sleeve 601 has multiple locking blocks 603 fixed on it, and the other reinforcing sleeve 601 has multiple locking slots 604 for securing the locking blocks 603. The protective sleeve 1 is made of ethylene propylene rubber, giving it good thermal conductivity and insulation properties. Multiple heat dissipation grooves 1 are provided on the protective sleeve 1. 01. The heat dissipation groove 101 is honeycomb-shaped. The heat dissipation groove 101 can increase the surface area of ​​the protective sleeve 1, thereby increasing the contact area between the protective sleeve 1 and the air and improving the heat dissipation effect. The inner side of the protective sleeve 1 is provided with a metal armor layer 5. The metal armor layer 5 is made of steel wire, which has good thermal conductivity. The inner side of the metal armor layer 5 is provided with a metal foil wrapping tape 4. Multiple conductive cores 2 are installed in the metal foil wrapping tape 4. The conductive cores 2 are made of copper or aluminum alloy, which gives them good conductivity. The outer side of the conductive cores 2 is provided with an inner semi-conductive shielding layer 201. The outer side of the inner semi-conductive shielding layer 201 is provided with an insulating sleeve 202. The outer side of the insulating sleeve 202 is provided with an outer semi-conductive shielding layer 203. Both the inner semi-conductive shielding layer 201 and the outer semi-conductive shielding layer 203 are made of conductive fiber composite material.

The protective sleeve 1 is provided with a filler 3. The filler 3 is made of polypropylene layer and fills the gaps.

[0023] Working principle: During use, this cable has an anti-over-bending mechanism 6 arranged at intervals on the protective sleeve 1. Because the reinforcing sleeve 601 is made of engineering plastic, it has high strength and poor deformation ability. When the cable bends to the reinforcing sleeve 601, it will be blocked, making it difficult for the cable near the reinforcing sleeve 601 to bend, thereby controlling the maximum bending angle of the cable and preventing mechanical damage caused by excessive bending. In addition, the heat generated by the conductive core 2 is transferred outward to the metal foil wrapping tape 4 and the metal armor layer 5. Both the metal foil wrapping tape 4 and the metal armor layer 5 are made of metal and have good thermal conductivity. The heat is transferred to the protective sleeve 1 through the metal armor layer 5. The protective sleeve 1 is provided with multiple honeycomb heat dissipation grooves 101. The heat dissipation grooves 101 can increase the surface area of ​​the protective sleeve 1, thereby increasing the contact area between the protective sleeve 1 and the air and improving the heat dissipation effect. The inner semi-conductive shielding layer 201 and the outer semi-conductive shielding layer 203 reduce external electromagnetic interference. The metal armor layer 5 can also improve the impact resistance and puncture resistance.
