Description

Technical Field

[0001] The utility model belongs to the technical field of cables, and in particular relates to a fault display cable. Background Art

[0002] When the damage to the cable is too small and the damaged point is difficult to observe, existing solutions, such as patent application No. 202021679530.0, discloses a fault display cable including a conductor, an insulation layer, and a reaction layer. When the cable is damaged, the damaged position of the cable can be directly determined by checking the specific display position of the reaction layer.

[0003] However, this method of displaying damaged parts still has many inconveniences in actual use. For example, when a cable is cut by a blade, the transparent protective layer will cause the entire color-changing layer to be colored by light, making it inconvenient to determine the specific location of the wound. Secondly, the wound where the color-changing layer is broken will be re-attached, and the fluorescent layer is located inside the color-changing layer. If the color-changing layer blocks light penetration, not only will the wound block light from irradiating the fluorescent layer, but the entire fluorescent layer will not be able to absorb the light source, and thus will not be able to release the light source to display the location. If the color-changing layer does not block light penetration, the entire fluorescent layer will absorb light, and then when the entire layer is bright, it is also inconvenient to determine the damaged location.

[0004] Therefore, a more intuitive method is needed to display the location of cable damage. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a fault display cable, in which an elastic band is fixed to the cable by a steel wire, which not only divides the elastic bands in the same side area into intervals with smaller spacing, but also makes the elastic bands in the intervals independent of each other. In this case, when the cable is damaged, the elastic bands in the interval will break, and the contracted elastic bands will leak out the inner cable sheath, indicating that the cable in the interval is faulty and damaged. Then the staff can intuitively observe the cable to see which interval the sheath is leaking, which indicates which area is damaged.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A fault display cable comprises a cable body, wherein the cable body comprises a conductor and an outer sheath, wherein the outer sheath is located at the outermost side of the conductor, an elastic band is spirally wound around the outer surface of the outer sheath, edges of the elastic band are in contact with each other, the elastic band is in a taut state, a steel wire is spirally wound around the outer surface of the elastic band, the pitch of the steel wire is 1 cm, and the rotation direction of the steel wire is opposite to that of the elastic band.

[0008] Furthermore, the outer surface of the outer skin is sprayed with reflective paint.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. An elastic band is fixed to the cable by a steel wire, which not only divides the elastic bands in the same side area into smaller intervals, but also makes the elastic bands in the intervals independent of each other. In this case, when the cable is damaged, the elastic band in the interval will break, and the contracted elastic band will leak out the inner cable sheath, indicating that the cable in the interval is damaged. Then the staff can observe the cable intuitively to see which interval the sheath is leaking, indicating which area is damaged.

[0011] 2. Reflective paint can increase the reflective effect of the outer skin, making the leaked outer skin easier to observe. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] 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 them. 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.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example

[0017] See attached Figure 1-2As shown, a fault display cable includes a cable body 1, the cable body 1 includes a conductor 11 and a sheath 12, the sheath 12 is located at the outermost side of the conductor 11, the outer surface of the sheath 12 is spirally wound with an elastic band 2, the edges of the elastic band 2 fit together, the elastic band 2 is in a taut state, the outer surface of the elastic band 2 is spirally wound with a steel wire 3, the pitch of the steel wire 3 is 1 cm, the rotation direction of the steel wire 3 is opposite to that of the elastic band 2, and the outer surface of the sheath 12 is sprayed with reflective paint.

[0018] Working principle: In the utility model, the elastic band 2 and the steel wire 3 are installed on the cable body 1 in a winding manner during the manufacturing process of the cable body 1. The elastic band 2 can be an elastic cloth band. When the cable is cut by a blade or damaged by other circumstances, a wound is caused on the cable body 1. The elastic band 2 at the wound will break, and the broken elastic band 2 will shrink toward the steel wire 3 that is pressed here, and then the cable sheath 12 leaks out here. Observing where the cable sheath 12 leaks out indicates which section is damaged. By observing the sheath 12 at the broken section, the specific damage condition of the cable body 1 can be found.

[0019] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
