When the cable is in use, it is squeezed or cut by the outside, and there is no buffer material inside, which can easily cause the internal cable body to be damaged and deformed; 2. When the cable is in use, it is burned by flames, and there is only a single layer of fireproof layer inside, which has poor fire protection and is easily directly burned and damaged. Utility Model Content
[0004] The purpose of the present invention is to provide an anti-crushing computer cable to solve the problems of poor cutting and crushing resistance and poor fire resistance of cables mentioned in the above background art. To achieve the above purpose, the present invention provides the following technical solution: an anti-crushing computer cable, comprising a cable housing, a fireproof layer attached to the bottom of the cable housing, a steel wire braided layer attached to the bottom of the fireproof layer, a mesh provided at the upper end of the steel wire braided layer, polyvinyl chloride attached to the bottom of the steel wire braided layer, the inner wall of the polyvinyl chloride provided with holes, a main fiber material layer attached to the bottom of the polyvinyl chloride, a support column attached to the bottom of the main fiber material layer, a secondary fiber material layer installed at the bottom of the support column, and a cable body attached to the bottom of the secondary fiber material layer.
[0005] Further preferably, the central axis of the fireproof layer coincides with the transverse central axis of the cable housing.
[0006] Further preferably, a plurality of circular mesh holes are provided at the upper end of the steel wire braided layer.
[0007] Further preferably, the inner wall of the polyvinyl chloride is provided with a plurality of circular holes.
[0008] Further preferably, the main fiber material layer is evenly arranged along the bottom of the polyvinyl chloride.
[0009] Further preferably, the support columns are arranged at equal angles with the center point of the cable body as the center.
[0010] Further preferably, the central axis of the secondary fiber material layer coincides with the transverse central axis of the primary fiber material layer.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] In the present invention, a steel wire braided layer and a support column are added. When the cable is subjected to external extrusion and cutting, the steel wire braided layer will first reduce a part of the force, and then the support column at the bottom of the main fiber material layer will expand and contract to relieve a part of the pressing force. The main fiber material layer can prevent external cutting damage. Through the cooperation of the main fiber material layer and the steel wire braided layer, layer by layer, the integrity of the internal cable body is protected to prevent the cable body from being damaged by external extrusion and cutting, which affects normal use.
[0013] In the utility model, a fireproof layer and polyvinyl chloride are added. When the cable is damaged by external flames, the fireproof layer will block the burning of the flames. Then, the holes inside the polyvinyl chloride can prevent the external burning temperature from being transmitted to the internal cable body. At the same time, the polyvinyl chloride will release inert gas when directly burned by flames to suppress the flames, thereby protecting the internal cable from being damaged by the flames and affecting its use.

[0021] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the central axis of the fireproof layer 2 coincides with the transverse central axis of the cable casing 1; by installing the fireproof layer 2 at the bottom of the cable casing 1, the fireproof layer 2 can isolate the external high temperature when a high-temperature fire occurs outside, thereby protecting the internal cable body 10 and preventing damage to the internal cable body 10.
[0022] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a plurality of circular mesh holes 4 are provided at the upper end of the steel wire braided layer 3. By providing a plurality of circular mesh holes 4 in the steel wire braided layer 3, the steel wire braided layer 3 can bend along with the cable body 10 when the cable body 10 bends, thereby increasing the flexibility of the steel wire braided layer 3.
[0023] In this embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the inner wall of the polyvinyl chloride 5 is provided with a plurality of circular holes 6; by providing a plurality of circular holes 6 inside the polyvinyl chloride 5, the circular holes 6 can reduce the contact surface with the interior when the polyvinyl chloride 5 is subjected to high temperature, thereby reducing temperature conduction.

The main fiber material layer 7 can prevent external cutting damage, and the main fiber material layer 7 and the steel wire braided layer 3 work together layer by layer to protect the integrity of the internal cable body 10. When a fire occurs externally and burns the cable body 10, the external fireproof layer 2 will block the burning of the flame, and then the holes 6 inside the polyvinyl chloride 5 can prevent the external burning temperature from being transmitted to the internal cable body 10. At the same time, the polyvinyl chloride 5 will release inert gas when directly burned by the flame to suppress the flame and protect the internal cable.
