[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0021] like Figure 1-2 As shown, the utility model provides a technical solution: a B1-class power cable, comprising an outer protection component 1 and a cavity 2 arranged inside the outer protection component 1, the inner circumferential wall of the cavity 2 is provided with a plurality of cores 4, the outer protection component 1 surrounds the plurality of cores 4 to form the cavity 2, the inner circumferential wall of the cavity 2 is fixedly connected with a plurality of triangular blocks 3, a spherical block 301 is arranged between every two adjacent triangular blocks 3, the spherical block 301 is fixedly connected to the inner circumferential wall of the cavity 2, arcuate walls 302 are provided on both sides of the plurality of triangular blocks 3, a connecting block 303 is arranged between two opposite triangular blocks 3, the curvature of the arcuate wall 302 is adapted to the curvature of the core 4, the heights of the two ends of the triangular blocks 3 based on the cavity 2 are smaller than the radius of the spherical block 301, and the connecting block 303 is arranged in a spiral shape.

[0022] Specifically: the outer protection component 1 is a structure surrounding the outer peripheral wall of the wire core 4, which is consistent with the cable structure in the prior art and will not be described in detail here;

[0023] During use, the internal structure is firstly wrapped around by the outer protection component 1 to form a cavity 2 inside, and a triangular block 3 is arranged in the cavity 2, and the triangular block 3 is fixed to the inner circumferential wall of the outer protection component 1, and at the same time, a distance can be left between every two triangular blocks 3 to serve as a buffer, and a spherical block 301 is arranged in this buffer space, and the spherical block 301 is also fixed to the inner circumferential wall of the outer protection component 1, and then the spherical block 301 and the arc-shaped walls 302 opened on both sides of the triangular block 3 are in contact with the wire core 4, and after each wire core 4 is in contact with the corresponding arc-shaped wall 302, the triangular block 3 can indirectly limit the position of multiple wire cores 4, and then based on this, the connecting block 303 is used to connect two non-adjacent triangular blocks 3. The corner blocks 3 are connected, and after a plurality of triangular blocks 3 are connected in this way, the arc-shaped wall 302 forms a spiral shape under the action of the connecting block 303, and then after limiting the wire core 4, the wire core 4 is also wound in a spiral shape, thereby increasing the tightness of the wire core 4 in the outer protection component 1. At the same time, since a distance is separated between each two adjacent triangular blocks 3, and then used as a buffer, when the user bends and routes the cable, the end of the triangular block 3 can be offset in the buffer, and then the distance between the ends of the two adjacent triangular blocks 3 is changed, thereby completing the bending of the cable, and avoiding the triangular block 3 and the arc-shaped wall 302 affecting the bending effect of the cable when limiting the wire core 4 to protect it;

[0024] On the contrary, during the bending process of the cable, since the height of the two ends of the triangular block 3 based on the cavity 2 is smaller than the radius of the spherical block 301, the spherical block 301 can contact the core 4 based on the outer protection component 1 during this process, thereby reducing the friction between the core 4 and the arc wall 302, so that the position where the distance between the ends of the triangular block 301 changes will not pull the core, thereby further ensuring the bending effect of the cable.

[0025] The working process of the utility model is as follows: firstly, the internal structure is surrounded and wrapped by the outer protection component 1 to form a cavity 2 inside, and a triangular block 3 is arranged in the cavity 2, and the triangular block 3 is fixed to the inner circumferential wall of the outer protection component 1, and at the same time, a distance can be separated between every two triangular blocks 3 to serve as a buffer, and a spherical block 301 is arranged in the buffer space, and the spherical block 301 is also fixed to the inner circumferential wall of the outer protection component 1, and then the spherical block 301 and the arc-shaped wall 302 opened on both sides of the triangular block 3 are in contact with the wire core 4, and after each wire core 4 is in contact with the corresponding arc-shaped wall 302, the triangular block 3 can indirectly limit the plurality of wire cores 4, and then based on this, two non-adjacent wire cores 4 are connected by the connecting block 303. The triangular blocks 3 are connected, and after the multiple triangular blocks 3 are connected in this way, the arc wall 302 forms a spiral shape under the action of the connecting block 303, and then after limiting the wire core 4, the wire core 4 is also wound in a spiral shape, thereby increasing the tightness of the wire core 4 in the outer protection component 1. At the same time, since a distance is separated between each two adjacent triangular blocks 3, and then used as a buffer, when the user bends and routes the cable, the end of the triangular block 3 can be offset in the buffer, and then the distance between the ends of the two adjacent triangular blocks 3 is changed, thereby completing the bending of the cable, and avoiding the triangular block 3 and the arc wall 302 affecting the bending effect of the cable when limiting the wire core 4 to protect it;

[0026] On the contrary, during the bending process of the cable, since the height of the two ends of the triangular block 3 based on the cavity 2 is smaller than the radius of the spherical block 301, the spherical block 301 can contact the core 4 based on the outer protection component 1 during this process, thereby reducing the friction between the core 4 and the arc wall 302, so that the position where the distance between the ends of the triangular block 301 changes will not pull the core, thereby further ensuring the bending effect of the cable.

[0027] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
