A plurality of hoses are evenly distributed along the circumference between the shunts, and the battery cell and the outer skin are located in the hose.
[0008] It also includes a limiting piece, and the hose is connected with three limiting pieces to facilitate limiting the hose;

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0020] A fire-resistant cable structure, such as Figure 1-Figure 3 As shown, it includes a battery core 1, a shell 2, a first connecting piece 3, a second connecting piece 4 and a cooling mechanism. The outer side of the battery core 1 is sleeved with the shell 2, and the shell 2 is made of waterproof material to prevent the cable from contacting water and causing a short circuit. The first connecting piece 3 is connected to the right side of the battery core 1, and the second connecting piece 4 is connected to the left side of the battery core 1. The outer shell 2 is provided with a cooling mechanism that can cool the cable.
[0021] like Figure 1 and Figure 4As shown, the cooling mechanism includes a diverter 5, a guide joint 6 and a hose 7. The left and right parts of the outer skin 2 are connected to the diverter 5, and the upper side of the diverter 5 is connected to the guide joint 6. Twelve hoses 7 are evenly distributed along the circumference between the diverters 5. The battery cell 1 and the outer skin 2 are located in the hose 7. A limiting member 8 is also included. Three limiting members 8 are connected to the hose 7 to facilitate limiting the hose 7. The guide joint 6 is connected to an external water pipe so that water flows into the hose 7 through the diverter 5, and the battery cell 1 and the outer skin 2 are located in the hose 7.
[0022] When using the device, first connect the first connector 3 with the second connector 4 on other cables to connect the battery cells 1 on different cables. After the connection is completed, connect the diversion joint 6 with the external water pipe to allow water to flow into the hose 7 through the diverter 5. The battery cell 1 and the outer skin 2 are located in the hose 7, so that the cable can be cooled to prevent the cable from heating up and causing spontaneous combustion. Then, the hose 7 is limited by the limiter 8 to prevent the hose 7 from collapsing after water is injected.
[0023] like Figure 2 and Figure 5 As shown, a protective mechanism is also included, which includes a first sliding sleeve 9 and a second sliding sleeve 10. The first sliding sleeve 9 is slidably connected to the right side of the outer skin 2, and the second sliding sleeve 10 is slidably connected to the left side of the outer skin 2. The first sliding sleeve 9 and the second sliding sleeve 10 are made of insulating materials to prevent short circuit. The first connecting member 3 is located in the first sliding sleeve 9, and the second connecting member 4 is located in the second sliding sleeve 10. When the cable is connected to the second connecting member 4 through the first connecting member 3, the first sliding sleeve 9 is connected to the second sliding sleeve 10 through a thread. The first sliding sleeve 9 and the second sliding sleeve 10 are slid so that the first sliding sleeve 9 contacts the second sliding sleeve 10, and then the second sliding sleeve 10 is rotated so that the second sliding sleeve 10 is connected to the first sliding sleeve 9 through a thread.
[0024] When the protection mechanism of the device is used, the first connecting member 3 and the second connecting member 4 can be protected. When the first connecting member 3 is connected to the second connecting member 4, the first sliding sleeve 9 and the second sliding sleeve 10 are slid so that the first sliding sleeve 9 contacts the second sliding sleeve 10, and then the second sliding sleeve 10 is rotated so that the second sliding sleeve 10 is connected to the first sliding sleeve 9 through a thread. Since the first sliding sleeve 9 and the second sliding sleeve 10 are made of insulating materials, the first connecting member 3 and the second connecting member 4 can be protected, and at the same time, a short circuit caused by poor contact when the first connecting member 3 and the second connecting member 4 are connected can be prevented.
