[0003] For example, a prestressed copper-clad steel stranded wire bundle with publication number CN215770560U relates to the technical field of copper-clad steel stranded wire. The prestressed copper-clad steel stranded wire bundle comprises a steel stranded wire, the outer wall of which is slidably connected to a zinc stranded wire, and the outer wall of which is provided with a first anti-skid groove. In the prestressed copper-clad steel stranded wire bundle, the copper stranded wire and the steel stranded wire are subjected to the friction of the first anti-skid groove, and the second anti-skid groove increases the wrapping force of the insulation skin on the copper stranded wire, thereby increasing the friction between the core wire bundle and the side wire bundle, preventing the core wire bundle from sliding to the edge, and increasing the stress of the wire bundle. The mass of aluminum is less than the mass of steel, and at this time, the weight of the steel-clad aluminum stranded wire will also be less than the weight of the steel stranded wire, and the cost of the aluminum material is also less than the cost of the steel material, thereby achieving the effect of reasonably controlling the weight of the copper-clad steel wire bundle and reducing the production cost, and the heat dissipation groove can effectively dissipate the heat of the wire bundle, reducing the probability of fire caused by excessive temperature of the wire bundle.

[0004] However, in the prior art, when the copper-clad steel stranded wire is transported or constructed, the insulating rubber layer on the outer wall collides with sharp objects, causing the insulating rubber layer to be damaged. During use, dust or rainwater will enter the interior of the stranded wire through the damaged area, causing internal corrosion. Utility Model Content

[0021] Reference Figure 1 - Figure 4The utility model provides a prestressed copper-clad steel stranded wire harness, including a harness body 1, the harness body 1 includes an insulating outer skin 11, the outer wall of the insulating outer skin 11 is provided with a heat dissipation groove 12 in an annular array, the outer wall of the insulating outer skin 11 is provided with a plurality of protective components 2, the protective component 2 includes a protective sleeve 21, the inner wall of the protective sleeve 21 is fixedly connected with a limiting rubber block 22 in an annular array, the limiting rubber block 22 is slidably connected with the heat dissipation groove 12, the two sides of the inner side of the protective sleeve 21 are fixedly connected with a sealing rubber ring 23, the middle part of the outer wall of the protective component 2 is provided with a fixing groove 24, the protective sleeve 21 A fixing member 25 is disposed inside the fixing groove 24. The fixing member 25 includes a fixing metal ring 251. The fixing metal ring 251 is divided into two ends and is slidably connected to the insulating outer skin 11. One end inside the fixing metal ring 251 is fixedly connected to a fixing plate 252. The fixing plate 252 is fixedly connected to the inside of the fixing groove 24. One end outside the fixing metal ring 251 is fixedly connected to a connecting plate 253. The connecting plate 253 contacts the fixing plate 252. A fixing hole 255 is opened in the middle of the connecting plate 253. The fixing hole 255 is internally threaded with a fixing bolt 254. The fixing bolt 254 passes through the connecting plate 253 and the fixing plate 252, and is threadedly connected with the fixing plate 252 and the protective sleeve 21. A protective assembly 2 is arranged at intervals on the stranded wire, and the fixing metal ring 251 on each protective assembly 2 is in the loosest state, so that the protective assembly 2 can be slightly fixed on the insulating rubber layer. When the copper-clad steel stranded wire is transported or constructed, the insulating rubber layer of the outer wall collides with a sharp object, causing the insulating rubber layer to be damaged. The nearest protective sleeve 21 can be pushed to the damaged area, and the movement of the protective sleeve 21 drives the limiting rubber block 22 to slide, and the limiting rubber block 22 slides in the heat dissipation groove 12, and the limiting rubber block 22 limits the protective sleeve 21. The internal wound is located in the middle of the sealing rubber ring 23, and then the fixing bolt 254 is taken out. At this time, the connecting plate 253 is separated from the fixing plate 252, and the staff pulls the connecting plate 253 downward to make the fixing metal ring 251 wrap and fix the protective sleeve 21, and then fix the connecting plate 253 and the fixing plate 252 by the fixing bolts 254, so that the protective sleeve 21 protects the damaged part, wherein the sealing rubber ring 23 can seal the interior of the protective sleeve 21, thereby sealing the damaged wound.

[0022] Reference Figure 1 and Figure 2The outer annular array inside the wiring harness body 1 is fixedly connected with the steel-clad aluminum stranded wire 13, and the inner annular array located inside the steel-clad aluminum stranded wire 13 in the insulating sheath 11 is fixedly connected with the copper stranded wire 14, and the copper stranded wire 14 is in contact with the steel-clad aluminum stranded wire 13. The steel stranded wire 16 is fixedly connected inside the insulating sheath 11, and the steel stranded wire 16 is in contact with the copper stranded wire 14. The zinc stranded wire 15 is fixedly connected in the gap between the steel stranded wire 16 and the copper stranded wire 14 inside the insulating sheath 11. The copper stranded wire 14 is located on the outer side of the steel-clad aluminum stranded wire 13, so friction is generated between the copper stranded wire 14 and the steel-clad aluminum stranded wire 13. The zinc stranded wire 15 is on the outer side of the steel stranded wire 16, so friction is generated between the steel stranded wire 16 and the copper stranded wire 14. The zinc stranded wire 15 is located in the gap generated by the contact between the copper stranded wire 14 and the steel stranded wire 16, so the zinc stranded wire 15 can increase the friction between the steel stranded wire 16 and the copper stranded wire 14, thereby increasing the stress.

[0023] The working principle of the utility model is as follows: first, when in use, the copper stranded wire 14 is located on the outside of the steel-clad aluminum stranded wire 13, so friction is generated between the copper stranded wire 14 and the steel-clad aluminum stranded wire 13, and the zinc stranded wire 15 is on the outside of the steel stranded wire 16, so friction is generated between the steel stranded wire 16 and the copper stranded wire 14, and the zinc stranded wire 15 is located in the gap generated by the contact between the copper stranded wire 14 and the steel stranded wire 16, so friction is applied between the steel stranded wire 16 and the copper stranded wire 14, thereby increasing the friction between the core wire bundle and the side wire bundle, and a protective component 2 is arranged at intervals on the stranded wire, and the fixed metal ring 251 on each protective component 2 is in the loosest state, so that the protective component 2 can be slightly fixed on the insulating rubber layer, and the insulation of the outer wall of the copper-clad steel stranded wire is slightly fixed when the copper-clad steel stranded wire is transported or constructed. The rubber layer collides with a sharp object, causing the insulating rubber layer to be damaged. The nearest protective cover 21 can be pushed to the damaged area. The movement of the protective cover 21 drives the limiting rubber block 22 to slide. The limiting rubber block 22 slides in the heat dissipation groove 12. The limiting rubber block 22 limits the protective cover 21. The internal wound is located in the middle of the sealing rubber ring 23. Then the fixing bolt 254 is taken out. At this time, the connecting plate 253 is separated from the fixing plate 252. The staff pulls the connecting plate 253 downward to make the fixing metal ring 251 wrap and fix the protective cover 21. Then the connecting plate 253 and the fixing plate 252 are fixed by the fixing bolts 254, so that the protective cover 21 protects the damaged area. Among them, the sealing rubber ring 23 can seal the interior of the protective cover 21, thereby sealing the damaged wound.
