[0031] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0032] like Figure 1 As shown, this embodiment provides a technical solution: a DC line with a magnetic ring, comprising;

[0033] DC cable body 1, with a magnetic ring 2 fixedly connected to the outside of DC cable body 1;

[0034] DC cable body 1 is the main part of the DC cable, used for power transmission. Magnetic ring 2 is fixed to the outside of DC cable body 1, and its main function is to suppress high-frequency noise and electromagnetic interference. When current flows through DC cable body 1, the magnetic ring generates a magnetic field, which can cancel or reduce electromagnetic interference in the surrounding environment.

[0035] like Figure 1 - Figure 3 As shown, the protection component 3 includes positioning posts 31 fixedly connected to both ends of the DC line body 1. A sleeve post 32 is slidably connected to the outside of the positioning post 31. A tension spring 33 is sleeved on the outside of the positioning post 31. A terminal 34 is fixedly connected to one end of the positioning post 31 near the tension spring 33. One end of the tension spring 33 is fixedly connected to the sleeve post 32, and the other end of the tension spring 33 is fixedly connected to the terminal 34.

[0036] Positioning posts 31 are fixed at both ends of the DC line body 1, providing mounting points for sleeve posts 32 and other components. Sleeve posts 32 are slidably connected to positioning posts 31, which can protect the internal terminals 34 from damage when subjected to external force. Tension spring 33 is located between positioning posts 31 and sleeve posts 32. When sleeve posts 32 are subjected to external force, tension spring 33 can be compressed or stretched, so that it can return to its original position after the external force disappears. This allows sleeve posts 32 to retract onto the outside of terminals 34 when needed, and protect terminals 34 internally after they are inserted. Terminals 34 are fixed to the end of positioning posts 31 near tension spring 33 and are electrically connected to the DC line body 1 or other equipment. The design of terminals 34 ensures reliable electrical contact.

[0037] like Figure 1 - Figure 4 As shown, the extension protection component 4 includes a groove 41 formed on the inner wall of the sleeve post 32, a slide rod 42 slidably connected inside the groove 41, a protective sleeve 43 fixedly connected to the end of the slide rod 42 away from the sleeve post 32, an outer ring 44 fixedly connected to the end of the protective sleeve 43 away from the positioning post 31, a push spring 45 provided inside the sleeve post 32, the elastic force ratio of the tension spring 33 to the push spring 45 is two to one, one end of the push spring 45 is fixedly connected to the inner wall of the sleeve post 32, and the other end of the push spring 45 is fixedly connected to the protective sleeve 43;

[0038] The sliding slot 41 is arranged on the inner wall of the sleeve column 32, and is used for guiding the movement direction of the sliding rod 42. The sliding rod 42 is slidably connected in the sliding slot 41, and one end of the sliding rod 42 is fixedly connected with the protective sleeve 43. The main function of the sliding rod 42 is to slide in the sliding slot 41 when an external force is applied, so as to drive the protective sleeve 43 to move correspondingly. The protective sleeve 43 is used for providing an additional protective layer for the internal structure, preventing impurities such as dust and dirt from entering the contact point of the terminal 34 and the connecting end. The outer ring 44 is designed to contact the outer side of the connecting end, and also provides a pushing point for the protective sleeve 43. The outer ring 44 realizes the sealing performance, and facilitates the movement of the whole assembly. The function of the push spring 45 is to push the outer ring 44 on the protective sleeve 43 to the surface of the connecting end when there is no external force, so as to keep the protective assembly in close contact. The elastic force ratio of the tension spring 33 and the push spring 45 is 2:1, which means that the elastic force of the push spring 45 is relatively small. The push force of the push spring 45 prevents the connection between the terminal 34 and the connecting end from generating a force in the opposite direction, so as to realize the protection of the terminal 34, and avoid the disconnection of the connection.

[0039] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application still belong to the protection scope of the present application.
