[0027] In order to keep the following description of the embodiments of the present invention clear and concise, the detailed description of known functions and known components is omitted in the present invention.

[0028] Embodiment 1

[0029] Please refer to Figures 1-4 As shown, in this embodiment, a power cable is provided, including a cable body 1 and its supporting first connector 2 and second connector 3.

[0030] The cable body 1 contains multiple battery cells 8 inside. Each battery cell 8 is tightly wrapped by an insulating layer 7 to ensure electrical isolation between the battery cells. A single corrosion-resistant layer 5 is sleeved outside the multiple insulating layers 7. The corrosion-resistant layer 5 is filled with a flame-retardant filling layer 6 inside. The flame-retardant filling layer 6 closely cooperates with the insulating layer 7, enhancing the flame-retardant performance of the cable. The outer surface of the corrosion-resistant layer 5 is fixedly sleeved with a protective layer 4 to further improve the corrosion resistance and mechanical protection ability of the cable. Among them, the protective layer 4 is woven from aramid fiber materials and has properties such as high temperature resistance, acid and alkali resistance, and good protective effect. The corrosion-resistant layer 5 is made of Teflon material, which has excellent chemical stability, strong corrosion resistance, and good sealing performance. The flame-retardant filling layer 6 is made of chlorosulfonated polyethylene material, which can effectively provide flame-retardant protection for the battery cells 8. The insulating layer 7 is specifically an insulating rubber sleeve, which can ensure the mutual insulation and independence of each battery cell 8 and ensure the stable power transmission effect.

[0031] The first connector 2 and the second connector 3 are respectively installed at both ends of the cable body 1. A first connection electrode 9 is fixedly installed inside the first connector 2. One end of the cable body 1 passes through the first connector 2 and is electrically connected to the first connection electrode 9. Similarly, a second connection electrode 16 is fixedly installed inside the second connector 3. The other end of the cable body 1 passes through the second connector 3 and is electrically connected to the second connection electrode 16. This design allows multiple cable bodies 1 to be electrically connected through the first connection electrode 9 and the second connection electrode 16 in the adjacent second connector 3, realizing the connection of the overall circuit.

[0032] Two limiting rods 10 are assembled on the outer wall of the first connector 2. One end of each limiting rod 10 is provided with a rectangular groove 11. An elastic bending piece 13 is installed in the rectangular groove 11. A limiting column 14 is fixed at a position near the end on one side of the elastic bending piece 13. The limiting column 14 extends out through the mounting hole 12 to achieve the locking function. Two fixing plates 17 are provided on the outer wall of the second connector 3, and a limiting groove 18 and a limiting hole 19 are opened inside. When the first connector 2 is docked with the second connector 3, the limiting rods 10 slide into the limiting groove 18. Through the elastic force of the elastic bending piece 13, the limiting column 14 passes through the limiting hole 19 to realize the stable connection of the two.

[0033] This application can be used in the field of cable technology and can also be used in other fields applicable to this application.

[0034] Embodiment 2

[0035] Reference Figure 3 、 4 Based on Embodiment 1, an improved corrosion-resistant and highly flame-retardant power cable is provided, which is applied to the field of cable technology;

[0036] Both of the two limit rods 10 are L-shaped. The shorter ends of the two limit rods 10 are fixedly connected to the first connector 2. There is a certain distance between the other ends of the two limit rods 10 and the outer wall of the first connector 2, so as to ensure that the subsequent mating limit slots 18 do not need to communicate with the inside of the second connector 3, thereby realizing the mutual independence of the connection between the first connector 2 and the second connector 3 and the connection between the limit rods 10 and the fixing plate 17, and further improving the sealing performance of the connection between the first connector 2 and the second connector 3.

[0037] To prevent external liquid from seeping into the inside of the connector, a plurality of sealing rings 15 are sleeved on the outer wall of the first connector 2. These sealing rings 15 are closely fitted with the inner wall of the second connector 3, effectively blocking the intrusion of external liquid.

[0038] In addition, two handles 20 are respectively provided on the outer walls of the first connector 2 and the second connector 3, which are convenient for users to manually separate or connect the two connectors when needed.

[0039] The usage process and working principle of the technical solution of the present utility model are as follows:

[0040] When the cable body 1 is in use, the external protective layer 4 and the corrosion-resistant layer 5 can provide good protection and corrosion resistance for the cable. At the same time, since the internal is filled with a flame-retardant filling layer 6, the cable also has good flame-retardant performance and can be applied to a variety of usage scenarios. When the cable is in use, the user can select the appropriate length and quantity of the cable body 1 according to the laying distance required by the cable. The first connectors 2 and the second connectors 3 are respectively installed at the head and tail ends of multiple cable bodies 1. Then, multiple cable bodies 1 can be laid in sequence, and the adjacent first connectors 2 and second connectors 3 can be used to complete the sequential assembly. When the first connector 2 and the second connector 3 are connected, the user needs to first bend the elastic bending piece 13 with the limit post 14 installed, keep the limit post 14 on the same side as the installation hole 12 and insert its bent end into the rectangular groove 11. Then, press the other two ends of the elastic bending piece 13 and insert the limit post 14 into the rectangular groove 11 as well. When the limit post 14 moves to the position of the installation hole 12, the limit post 14 will be snapped into the installation hole 12 under the elastic action of the elastic bending piece 13. After that, the user can insert the first connector 2 into the second connector 3 and press the limit posts 14 on both sides to make the two limit rods 10 inserted into the limit grooves 18 until the limit posts 14 pop out from the limit holes 19. After the first connector 2 is snapped into the second connector 3, multiple sealing rings 15 can fully seal the gap between the first connector 2 and the second connector 3. And since the limit groove 18 is independent of the inside of the second connector 3, the engagement of the limit rod 10 and the fixed plate 17 will not affect the sealing between the first connector 2 and the second connector 3, which can ensure a good connection effect between the two cable bodies 1. When the user needs to separate the two cable bodies 1, the two limit posts 14 can be pressed to retract them, and then the first connector 2 and the second connector 3 can be separated forcefully using the handles 20 on the first connector 2 and the second connector 3.
