[0003] However, when using cables in electric vehicle charging facilities, existing cables do not have effective buffer components inside. This causes them to be subjected to significant compression layer by layer from the outer insulation layer to the inner core when bent, resulting in minor breakage and damage to the middle filling layer.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0030] 1. Equipped with a buffer protection component, the buffer pressing block is separated from the flame-retardant sliding belt. The buffer pressing block is fitted with the power supply core. The buffer pressing block and the flame-retardant sliding belt swing together to realize pressing and displacement, reducing the direct impact of rigid pressing, reducing the damage to the power supply core caused by reciprocating torsion and pressing, and improving the stability and service life of the core. The inner insulating elastic sleeve pushes the multi-hole mating plate to the side, and the inner limiting shielding strip presses the multi-hole mating plate to the side. Through bidirectional synchronous pressing, and by using the multi-hole mating plate to press and stretch layer by layer, and bend and fill each other, the rigid pressure on the components under internal pressure is reduced, and the direct damage to the internal filling is avoided.
[0031] The internal structure is reinforced with elastic relay columns, textile reinforcing ropes, double-concave hollow plates, and inner limiting reinforcing strips to enhance tensile strength. External elastic buffering is provided during pulling, and the gaps between multiple components are twisted and pressed together to improve the cable's tensile and torsional resistance. This allows for stable buffering, improving the stability of its support and integration. Heat-resistant silicone sleeves and elastic pressing blocks are used to buffer multiple sets of relay limiting sleeves. Combined with locking positioning plates and buffer linkage plates, segmented positioning support is achieved, realizing multi-segment combined support and buffer elastic support. This increases the range of cable bending and twisting, ensuring operational stability and enhancing its bending strength.
[0032] Through a gradual buffering process from the inside out, and by using gap twisting and elastic expansion and compression between multiple components, combined with multi-segment braiding reinforcement and tensile limiting, the problem of insufficient internal elastic support when bending due to the lack of effective buffer components in the cable is effectively solved in the existing technology. This results in minor breakage and damage to the filler material. The cable can be used to ensure its overall insulation and support protection, thereby improving its stability and service life.
[0033] 2. An outer protective assembly is provided. The wear-resistant composite sheet is attached to the side of the reinforced elastic sleeve, and the pressure-resistant anti-penetration sheet is bonded to the side of the wear-resistant composite sheet. A double-clamp isolation sleeve is then bonded to the side of the reinforced elastic sleeve. The wear-resistant composite sheet and the pressure-resistant anti-penetration sheet are pressed and limited, blocking and resisting sharp external objects and buffering and reducing wear from reciprocating contact friction. This reduces cable insulation loss and improves the stability of cable laying and continuous use. The isolation treatment sheet is bonded to the side of the pressure-resistant anti-penetration sheet and the double-clamp isolation sleeve, respectively. An anti-UV treatment sheet is then bonded to the side of the reinforced elastic sleeve. The isolation treatment sheet and the anti-UV treatment sheet block ultraviolet rays, reducing the impact of ultraviolet rays on the reinforced elastic sleeve, slowing down the aging rate of the cable exposed to light, and extending its service life.
[0034] In summary, by cooperating with the buffer protection components and the outer sheath components, and through the internal elastic support and elastic buffering, the central elastic compression and elastic torsion fit, and the external anti-wear and anti-puncture fit, effective buffering and buffering treatment can be carried out during cable use, thereby improving the cable protection effect, extending its service life, and ensuring stable operation of the cable during continuous use.

[0056] Multiple buffer pressing blocks 209 have power supply wire cores 210 sleeved on their inner ends;

[0061] A contact buffer strip 219 is bonded to the side end of the outer limiting shielding strip 218. The side ends of two adjacent contact buffer strips 219 are attached to each other to achieve a buffer contact combination, ensuring the stability of isolation restriction and elastic expansion. A stab-proof limiting strip 220 is laid on the outer end of the contact buffer strip 219.

[0062] Multiple anti-stab limiting bands 220 are fitted with woven limiting sleeves 221 on their outer ends, and intermediate pressing sleeves 222 are fitted with intermediate pressing sleeves 222 on their outer ends. Several buffer treatment holes 223 are equidistantly opened on the side ends of the intermediate pressing sleeves 222.
[0063] An armored anti-stab sleeve 224 is sleeved on the outer end of the relay pressing sleeve 222. The outer diameter of the relay pressing sleeve 222 is equal to the inner diameter of the armored anti-stab sleeve 224, so as to achieve alignment and sealing isolation. A reinforced elastic sleeve 225 is sleeved on the outer end of the armored anti-stab sleeve 224.
[0064] The side end of the reinforced elastic sleeve 225 is provided with an outer protective component 3;
[0065] The outer protective component 3 includes an anti-ultraviolet treatment sheet 301, an abrasion-resistant composite sheet 302, a pressure-resistant and puncture-resistant sheet 303, a double-clamp isolation sleeve 304, and an isolation treatment sheet 305;
[0066] An anti-UV treatment sheet 301 is bonded to the outer end of the reinforcing elastic sleeve 225. The side end of the anti-UV treatment sheet 301 is fitted with the side end of the double-clamp isolation sleeve 304 to ensure the stability of the overall sealing and isolation. Several wear-resistant combination sheets 302 are bonded at equal intervals to the outer end of the reinforcing elastic sleeve 225. Several pressure-resistant anti-penetration sheets 303 are bonded at equal intervals to the side end of the wear-resistant combination sheets 302. A double-clamp isolation sleeve 304 is sleeved at the position of the wear-resistant combination sheet 302 on the side end of the reinforcing elastic sleeve 225. The longitudinal section of the double-clamp isolation sleeve 304 is L-shaped. The inner end of the double-clamp isolation sleeve 304 is fitted with the outer end of the pressure-resistant anti-penetration sheet 303 to achieve support, locking and alignment sealing. An isolation treatment sheet 305 is bonded between the two double-clamp isolation sleeves 304.
[0067] The working principle and usage process of this invention are as follows: During cable laying, workers attach the wear-resistant composite sheet 302 to the side of the reinforcing elastic sleeve 225 according to the actual environment, and then attach the pressure-resistant anti-penetration sheet 303 to the side of the wear-resistant composite sheet 302. Finally, they attach the double-clamp isolation sleeve 304 to the side of the reinforcing elastic sleeve 225, pressing and limiting the sides of the wear-resistant composite sheet 302 and the pressure-resistant anti-penetration sheet 303. After pressing, the side of the isolation treatment sheet 305 is then bonded to both the pressure-resistant anti-penetration sheet 303 and the double-clamp isolation sleeve 304, thereby completing the overall assembly. The limiting connection uses wear-resistant composite plate 302 and pressure-resistant anti-penetration plate 303 to block and resist external sharp objects, and buffer and reduce the wear of reciprocating contact friction, thereby reducing the loss of the cable insulation layer and improving the stability of cable laying and continuous use. Then, the UV-resistant treatment plate 301 is bonded to the side end of the reinforcing elastic sleeve 225. The isolation treatment plate 305 and the UV-resistant treatment plate 301 block ultraviolet rays, reduce the impact of ultraviolet rays on the reinforcing elastic sleeve 225, slow down the aging rate of the cable exposed to light, and extend its service life.
[0068] When the cable is in use, power is supplied through the power core 210. During vehicle charging, the cable undergoes repeated bending and twisting. At this time, the internal components of the cable separate from the buffer compression block 209 via the flame-retardant sliding band 208. The buffer compression block 209 causes the power core 210 to twist slightly along the flame-retardant sliding band 208, preventing it from undergoing large-scale twisting. During compression, the buffer compression block 209 performs compression oscillation, achieving compression displacement and reducing the direct impact of rigid compression. This allows the power core 210 inside the cable to effectively undergo elastic compression and torsional buffering during use, reducing damage from reciprocating rigid torsion and compression, and improving its operational stability and usability. When the inner insulating elastic sleeve 207 is bent, it will push the porous mating plate 206 to the side. When the porous mating plate 206 is under pressure, it will press against the other porous mating plates 206 on the side and perform its own pressing process, increasing the buffer gap and pressing gap of the inner insulating elastic sleeve 207. At the same time, the outer inner limit shielding strip 205 is pressed inward. When one end of the cable is pressed, the other side is stretched, achieving steady filling and ensuring the stability of the overall internal protection. At this time, through the bending and elastic pressing of the relay elastic column 204, the overall support is provided while performing elastic load bearing and limiting treatment, so that the pressing protection can be handled steadily, improving the degree of overall bending and buffering.
[0069] The cable is isolated and protected on the outside by the relay limiting sleeve 1 and the textile reinforcing rope 201, and the inside is elastically buffered by the double concave hollow plate 202. The inside is reinforced with the inner limiting reinforcing strip 203, the textile reinforcing rope 201 and the relay elastic column 204 to enhance the tensile strength of the cable, thereby improving the cable's tensile and torsional resistance. Furthermore, the cable can be steadily buffered during torsion, stretching and bending, thereby improving the stability of its support limitation and support integration.
[0070] The heat-insulating and flame-retardant strip 211 and the flame-retardant sliding strip 208 are used for step-by-step and position-by-position flame-retardant treatment. The heat-resistant silicone sleeve 212 and the elastic pressing block 213 are used to buffer the multiple sets of relay limiting sleeves 1. At this time, the outer side is squeezed inward and the inner side is pushed outward, so that the multiple sets of relay limiting sleeves 1 cooperate and buffer each other. The locking positioning plate 215 and the buffer linkage plate 216 are used for segmented positioning support, and multiple buffer linkage plates 216 buffer and support the locking positioning plate 215. The middle limit reinforcing rope 214 is used to support the elastic pressing block 213, the heat-resistant silicone sleeve 212, the locking positioning plate 215 and the buffer linkage plate. 216 is used for combined positioning to achieve multi-segment combined support and buffer elastic support, improve the range of cable bending and twisting, ensure its operational stability, and improve its bending strength. The outer protective effect of the cable is strengthened layer by layer by the outer limiting shielding strip 218, the anti-stab limiting strip 220, the braided limiting sleeve 221, and the armored anti-stab sleeve 224. The contact buffer strip 219, the relay pressing sleeve 222, and the buffer treatment hole 223 are used to place and buffer the outer compression. The relay pressing sleeve 222 and the reinforced elastic sleeve 225 are used for overall integrated support and protective support, which improves the stability of the outer insulation support limit.
