[0002] With the popularity of electric vehicles, electric vehicle charging stations can better solve the problem of fast charging through charging piles, save energy and reduce emissions. Charging pile cables are usually rope-like cables made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering.

[0003] The cables of existing charging piles are heavy. When using the charging pile cables of new energy vehicles, the connection between the cable and the charging head is often bent and torn. In the existing technology, a corrugated flexible rubber sleeve is often set at the connection between the cable and the charging head to protect the connection. Although this solution can protect the connection, the corrugated flexible rubber sleeve will age after long-term use, and its bending and tearing resistance will decrease. After aging, the corrugated flexible rubber sleeve cannot be replaced. After damage, the cable can only be replaced, and the service life is short. Utility Model Content

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0025] Example: Figure 1-5 As shown, the utility model provides a technical solution for a tear-proof and bending-resistant new energy charging pile cable, comprising a conductor 1, an isolation tube 2 filled in the middle of the conductor 1, an inner leather strip 3 embedded in the isolation tube 2, and separation capsules 4 evenly arranged on the outside of the isolation tube 2. The separation capsules 4 are located between two adjacent conductors 1, and the separation capsules 4 are filled with rubber balls 5. The separation capsules 4 can separate each conductor 1 to prevent twisting between the conductors 1. When the cable is subjected to external pressure, the rubber balls 5 are elastic and can buffer the external pressure. Several separation capsules 4 are connected with inner springs 6 in pairs. The elasticity of the inner springs 6 can improve the bending resistance of the cable. The outside of the conductor 1 is wrapped with a wrapping layer 8, and the gap between the conductor 1 and the wrapping layer 8 is filled with a silicone strip 7. The outside of the wrapping layer 8 is wrapped with an armor layer 9, and the outside of the armor layer 9 is wrapped with a rubber protective layer 10.

[0026] One end of the conductor 1 is connected to a charging handle 21, and a connecting ring 11 is bonded to the outside of the rubber protective layer 10 near the charging handle 21. The outside of the connecting ring 11 is evenly wrapped with a first external card 12. Two external rings 13 are bonded to the outside of the rubber protective layer 10 at one end of the connecting ring 11. Connecting ears 14 are provided at one end of the first external card 12 and at both ends of the external ring 13. An outer skin strip 15 is connected between the first external card 12 and the adjacent external ring 13 through the connecting ear 14. An outer skin strip 15 is also connected between the two external rings 13 through the connecting ear 14. The outer skin strip 15, the inner skin strip 3 and the inner spring 6 cooperate with each other. When the cable is bent by external force, the cable can quickly return to its original shape when the external force is withdrawn;

[0027] A connecting groove 16 is provided at one end of the outer side of the charging handle 21, and a second external card 17 is evenly sleeved on the outer side of the connecting groove 16. One end of the second external card 17 and the other end of the first external card 12 are connected to a protective spring 19 through a connecting block 18. Metal fixing hoops 20 are fixed to the outside of the first external card 12 and the second external card 17. The connecting ring 11, the first external card 12, the external ring 13 and the second external card 17 are made of metal iron. The metal fixing hoop 20 can fix the first external card 12 and the second external card 17. When the protective spring 19 ages, it is convenient to disassemble the first external card 12 and the second external card 17.

[0028] The working principle and usage process of the utility model are as follows: separation capsules 4 are evenly arranged on the outside of the isolation tube 2. The isolation tube 2 and the separation capsule 4 can separate each conductor 1 to prevent twisting between the conductors 1. When the cable is subjected to external pressure, the silicone strip 7 initially absorbs and buffers the external pressure, and the separation capsule 4 is filled with rubber balls 5. The rubber balls 5 are elastic and buffer the external pressure again, and the cable has better pressure resistance. Inner springs 6 are connected between each of the separation capsules 4. When the cable is bent, the inner springs stretch. The elasticity of the inner springs 6 can improve the bending resistance of the cable, and the inner strips 3 and the inner springs 6 further improve the bending resistance of the cable. When the charging handle 21 and the cable connection are subjected to external force, the inner strips 3, the inner springs 6 and the outer strips 15 can simultaneously resist the external force to avoid excessive bending of the connection. The bending resistance and tearing resistance are high, and the service life of the cable is extended. The outer strips 15 are connected by connecting ears 14. When the outer strips 15 are aged, the aged outer strips 15 can be quickly replaced, which is convenient and fast.

[0029] When the connection between the charging handle 21 and the cable is subjected to external force, the protective spring 19 is also bent by the force. The protective spring 19 deforms to buffer the external force, further improving the bending resistance of the connection. The metal fixing hoop 20 can fix the first external card 12 and the second external card 17. When the protective spring 19 ages, loosen the metal fixing hoop 20, remove the first external card 12 and the second external card 17 from the outside of the connecting ring 11 and the connecting groove 16, and replace the new protective spring 19. This ensures that the charging handle 21 and the cable always have strong bending and tearing resistance, and the charging pile cable has a longer service life.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
