Description

Technical Field

[0001] The utility model relates to the technical field of cables, and in particular to a pressure-resistant charging pile cable. Background Art

[0002] With the popularity of electric vehicles, charging piles are used more and more frequently as important supporting facilities for electric vehicles. As a bridge connecting charging piles and electric vehicles, the quality and performance of charging pile cables are directly related to charging efficiency and safety.

[0003] In the actual use of charging pile cables, due to the diversity of vehicle parking, the complexity of the charging environment and the irregularities of human operation, the cables are often easily squeezed, rubbed and pulled by external forces, causing cable damage and affecting the charging effect and safety. Traditional charging pile cables usually adopt ordinary cable structures, which have limited pressure resistance, anti-extrusion and anti-friction capabilities, and are difficult to meet the use requirements in complex environments. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that due to the diversity of vehicle parking, the complexity of the charging environment and the irregularity of human operation, the pressure resistance and anti-extrusion and anti-friction capabilities are limited, and it is difficult to meet the use requirements in complex environments, and a pressure-resistant charging pile cable is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pressure-resistant charging pile cable, comprising a cable core and a cable outer layer, wherein the cable outer layer is wrapped around the circumference of the cable core, the cable core is composed of a plurality of wire cores, the circumferential outer walls of the wire cores are all provided with an insulating layer, and the cable outer layer comprises a pressure-resistant layer and a steel wire braided layer;

[0007] The anti-pressure layer is made of polyurethane material and is arranged inside the circumference of the steel wire braided layer;

[0008] A plurality of cushion blocks are installed outside the circumference of the cable, and the cables all pass through the interior of the cushion blocks, which are made of rubber.

[0009] In a possible design, two protrusions are fixedly connected to one side of the cushion block, and a groove is provided on the other side of the protrusion, and the protrusion and the groove match each other.

[0010] In a possible design, a plurality of penetrating extrusion holes are provided on one side of the cushion block.

[0011] In a possible design, a plurality of friction grooves are provided on the surface of the pad.

[0012] In a possible design, a pressure-resistant ring is provided inside the spacer, and the pressure-resistant ring is located outside the circumference of the cable.

[0013] In a possible design, the outside of the multiple cores is wrapped with the same protective layer to protect the cores from being damaged.

[0014] In a possible design, a wear-resistant layer is provided between the pressure-resistant layer and the steel wire braided layer, and the wear-resistant layer is made of nylon material.

[0015] In a possible design, a metal shielding layer is provided outside the circumference of the steel wire braided layer.

[0016] In this application, when the voltage-resistant charging pile cable is in working condition, the wire core in the cable core is responsible for transmitting electrical energy, the insulation layer ensures electrical isolation between the wire cores to prevent short circuits, and the protective layer protects the wire core from external physical damage;

[0017] The compression layer in the outer layer of the cable is made of polyurethane material, which can provide good pressure resistance and prevent the cable from being damaged under high pressure. The wear-resistant layer increases the wear resistance of the cable and extends the service life of the cable. The steel wire braided layer provides mechanical strength and tensile resistance to ensure that the cable is not easy to break when subjected to external force. The metal shielding layer prevents electromagnetic interference and ensures the stability of power transmission.

[0018] The pad is installed outside the circumference of the cable to provide additional protection for the cable. The bump and groove design of the pad allows multiple pads to be spliced ​​together to adapt to cables of different lengths. The extrusion hole and friction groove increase the elasticity and friction of the pad respectively to ensure that the pad is stably fixed on the cable. The pressure-resistant ring further enhances the pressure resistance of the cable in the pad area.

[0019] When the cable is subjected to external pressure or impact, the pads and pressure-resistant rings can absorb and disperse these forces, reducing damage to the cable core. At the same time, the structure of the cable outer layer also provides additional protection to ensure that the cable can work stably in harsh environments.

[0020] Beneficial effects:

[0021] In the utility model, the pressure-resistant charging pile cable described above adopts polyurethane material as the pressure-resistant layer on the outer layer of the cable, thereby improving the pressure-resistant performance of the cable. The pressure-resistant layer is arranged inside the circumference of the steel wire braided layer, thereby effectively enhancing the anti-extrusion ability of the cable, so that the cable is not easily deformed or damaged when subjected to external force extrusion.

[0022] In the utility model, a pressure-resistant charging pile cable is described, and a plurality of rubber pads are installed on the outside of the circumference of the cable, and the pads penetrate the cable, which effectively disperses the external pressure on the cable and further enhances the cable's anti-extrusion ability.
