Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a flame-retardant cable for electric vehicles. Background Technology

[0002] Flame-retardant cables for electric vehicles are an important component in ensuring the safety performance of electric vehicles. Their main function is to transmit electrical energy, while also possessing good flame-retardant properties to prevent the spread of fire in the event of a short circuit or fire. In electric vehicles, cables are the bridge connecting key components such as batteries, motors, and controllers. Flame-retardant cables can effectively prevent the spread of fire in the event of a fire, providing passengers with valuable escape time and reducing the risk of the vehicle being completely burned. The flame-retardant properties of flame-retardant cables are their core characteristics.

[0003] However, common flame-retardant cables for electric vehicles are inconvenient to splice during use. When splicing, the connection method is mainly through tape. Moreover, there are no internal components for separation of the cables. In the event of a fire, it is not convenient to retard the flames, which can easily lead to the entire cable catching fire. Therefore, there is still room for further improvement.

[0004] Therefore, we propose a flame-retardant cable for electric vehicles to address the problems mentioned above. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0027] This embodiment is a flame-retardant cable for electric vehicles.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a connecting component 2 is provided on the side of the cable housing 1. The connecting component 2 includes a connecting sleeve 3, a conical ring 4, a retaining ring 5, and a threaded wire 6. The connecting sleeve 3 is slidably connected to the cable housing 1, the conical ring 4 is slidably connected to the cable housing 1, and the conical ring 4 is slidably connected to the retaining ring 5. The retaining ring 5 is provided on the left side of the cable housing 1. The retaining ring 5 is located to the left of the connecting sleeve 3 and the conical ring 4. The threaded wire 6 is located on the right side of the cable housing 1. The connecting sleeve 3 and the threaded wire 6 are threadedly connected.

[0029] like Figure 1 and Figure 4 As shown, a connecting shaft 7 is provided inside the cable housing 1, and a partition plate 8 is provided on the outside of the connecting shaft 7. The partition plates 8 are arranged in an array, and protrusions 9 are provided at both ends of the outer side of the partition plate 8. A groove 10 is provided in the middle of the outer side of the partition plate 8. A slot 11 is provided on the left side of the connecting shaft 7, and a connecting block 12 is provided on the right side of the cable housing 1. The slot 11 and the connecting block 12 are rotatably connected. Cable bodies 13 are arranged in an array inside the cable housing 1, and the cable bodies 13 correspond one-to-one with the partition plates 8.

[0030] It should be noted that the cable housing 1, connecting components 2, partition plate 8, protrusion 9 and groove 10 are all made of silicone rubber. Silicone rubber is the first choice for insulation material of high voltage cables for electric vehicles because it has the characteristics of high and low temperature resistance, arc resistance, leakage tracking resistance, good insulation performance and flame retardancy. It has a certain flame retardant effect. In addition, the inside of the cable housing 1 is also filled with sealed flame retardant rubber to prevent the cable components inside the cable housing 1 from shaking. Specific Implementation Example 2

[0032] This embodiment is designed to address the problem that the cable housing 1 is not tightly connected during extension connections, which can lead to combustion.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, during use, connect the cable body 13 together, then hold the cable shell 1 with the threaded wire 6 connected to it, and then connect the connecting sleeve 3 on the outside of the other cable shell 1 to the threaded wire 6. At this time, the connecting sleeve 3 will gradually move closer to the retaining ring 5 and then come into contact with the conical ring 4. Since the thickness of the left end of the conical ring 4 is greater than the thickness of the right end, the connecting sleeve 3 will gradually squeeze the conical ring 4. At this time, the cable shell 1, the connecting sleeve 3 and the conical ring 4 will be tightly connected, thereby achieving a tight connection and preventing water or dust from entering the connection, thus achieving the purpose of flame retardancy. Specific Implementation Example 3

[0035] This embodiment is designed to address the problem that the combustion of one cable body 13 can cause all cable bodies 13 to burn.

[0036] like Figure 1 and Figure 4 As shown, the interior of the cable shell 1 is divided into three spaces by the connecting shaft 7, the partition plate 8, the protrusion 9, and the groove 10. The protrusion 9 and the groove 10 can increase the connection area between the cable shell 1 and the partition plate 8, which has the function of tight connection. The cable bodies 13 do not contact each other. When one cable body 13 is burning, the connecting shaft 7 and the partition plate 8 will form a barrier, and the unburned cable body 13 will not be passively burned, which further plays a flame-retardant role. The connecting shaft 7 has a slot 11 on its side and a connecting block 12 on its side. The connecting shafts 7 are connected together by the slot 11 and the connecting block 12. When the cable shell 1 is bent, the connected connecting shafts 7 will deform, which facilitates bending and increases flexibility and stability.
