[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example: A transverse watertight cable passing through an insulating sealing sleeve, such as Figures 1-4 As shown, the cable includes a sealing sleeve body 1, with sealing rings 2 movably disposed on both sides of the inner wall of the sealing sleeve body 1, a protective sleeve 3 fitted onto the surface of the sealing sleeve body 1, and connecting nuts 4 movably disposed on both sides of the sealing sleeve. The sealing rings 2 engage with the connecting nuts 4. Several deformation grooves 5 are formed on the surface of the sealing sleeve body 1, and reinforcing plates 6 are fitted onto the inner walls of the deformation grooves 5. Several heat dissipation grooves 7 are formed on the surface of the protective sleeve. The sealing sleeve body 1 should have a certain degree of elasticity. The inner wall of the sealing sleeve body 1 is threadedly connected to the surface of the sealing rings 2. The combination of the rubber sealing rings and the compression nuts forms a double sealing structure, effectively improving the watertightness. The heat dissipation grooves on the protective sleeve increase the heat dissipation area, improve the heat dissipation efficiency of the cable, and ensure the stability of the cable under long-term operation.

[0026] like Figures 1-4 As shown, a cable groove 8 is provided on the surface of the sealing ring 2, and a through hole 9 is provided on the surface of the connecting nut 4. The through hole 9 is consistent with the inner diameter of the cable groove 8. A rubber skin 10 is fixedly provided on the inner wall of the cable groove 8. The rubber skin 10 is an elastic film made of rubber. The rubber skin 10 is viewed as a ring shape, and the inner diameter of the central through hole 9 is slightly smaller than the outer diameter of the cable. The reinforcing plate 6 has a certain thermal conductivity and is parallel to the heat dissipation groove 7.

[0027] like Figures 1-3 As shown, one side of the connecting nut 4 is threaded to the inner wall of the sealing sleeve body 1. Several plug rods 11 are fixedly installed on one side of the connecting nut 4. Several plug holes 12 are opened on the surface of the sealing ring 2. The number of plug holes 12 corresponds to the number of plug rods 11, and they are engaged with each other. Tightening the connecting nut 4 causes the sealing ring 2 to rotate. All parts are fixed by threaded connection and positioning ring, which makes installation and disassembly convenient and facilitates later maintenance and replacement.

[0028] Working principle: when the cable needs to cross the isolation area, the transverse watertight cable is installed on the cable through the sealing sleeve body 1. By tightening the compression nut, its conical compression surface compresses the rubber sealing ring 2, so that the sealing ring 2 is tightly attached to the cable and the sealing sleeve body 1, forming a sealed space to prevent water and other liquids from entering, and the sealing ring 2 protects the internal parts from the influence of the external environment, and the reinforcing sheet 6 helps the cable to dissipate heat, ensuring stable operation of the whole device.

[0029] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
