[0030] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0031] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0032] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0033] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0034] Example, see Figure 1 , which is an embodiment of the utility model, proposes a computer cable, including a sheath layer 1, an isolation sleeve 2, a cable core 3, a filling layer 4, and an outer waterproof layer 5. The isolation sleeve 2 is arranged inside the sheath layer 1; the cable core 3 is located inside the isolation sleeve 2; the filling layer 4 is located between the cable core 3 and the isolation sleeve 2; and the outer waterproof layer 5 is arranged between the isolation sleeve 2 and the filling layer 4.

[0035] Furthermore, if Figure 1 As shown, it also includes an inner waterproof layer 6, which is arranged between the cable core 3 and the filling layer 4. The inner waterproof layer 6 is used to cover the cable core 3, which can further improve the waterproof effect.

[0036] Furthermore, if Figure 1As shown, it also includes a shielding layer 7, which is arranged on the cable core 3 and is located outside the inner waterproof layer 6. The shielding layer 7 is used to make the computer cable have the ability to resist external electromagnetic interference, and at the same time, it can avoid affecting the surrounding components. The shielding layer 7 is a layered structure formed by overlapping and wrapping copper tape or aluminum-plastic composite tape. The thickness of the copper tape or aluminum-plastic composite tape is 0.04~0.15mm, preferably 0.04mm, 0.15mm, or 0.10mm. Under the premise of ensuring effective shielding, the thickness of the copper tape or aluminum-plastic composite tape is reduced as much as possible, which can reduce the amount used and save costs.

[0037] Furthermore, if Figure 2 As shown, the cable core 3 includes a conductor 3-1 and an insulating layer 3-2. The insulating layer 3-2 is arranged on the periphery of the conductor 3-1, and the inner waterproof layer 6 is arranged on the periphery of the insulating layer 3-2. The insulating layer 3-2 insulates the conductor 3-1 from the surrounding environment or the adjacent conductors 3-1, ensuring that the current, electromagnetic waves or light waves transmitted by the cable core 3 only propagate along the conductor 3-1 and do not flow to the outside world, while ensuring the safety of external objects and personnel. The insulating layer 3-2 is a layered structure made of irradiated cross-linked polyethylene, which can prevent steam and flames from entering the electrical equipment connected to the computer cable, and has higher explosion-proof performance.

[0038] Furthermore, if Figure 3 As shown, the sheath layer 1 includes an inner lining layer 1-1, a flame retardant layer 1-2, and an outer sheath 1-3. The inner lining layer 1-1 is arranged on the periphery of the isolation sleeve 2; the flame retardant layer 1-2 is arranged on the periphery of the inner lining layer 1-1; and the outer sheath 1-3 is arranged on the periphery of the flame retardant layer 1-2. The inner lining layer 1-1 can play a positioning role for the components located inside it, the outer sheath 1-3 can play a protective role for the components inside it, and the flame retardant layer 1-2 can effectively play a flame retardant and fireproofing role. The outer sheath 1-3 is a layered structure made of polyamide fiber, which can improve the overall toughness and tensile strength of the computer cable. The flame retardant layer 1-2 is a layered structure made of glass fiber, which can improve the fire resistance of the computer cable.

[0039] In this embodiment, the number of cable cores 3 is at least two, and an inner waterproof layer 6 and a shielding layer 7 are arranged on the periphery of each cable core 3, and the shielding layer 7 is located on the periphery of the inner waterproof layer 6. A filling layer 4 is arranged between the shielding layers 7 of adjacent cable cores 3 and between the shielding layer 7 and the outer waterproof layer 5. The filling layer 4 is used to isolate adjacent cable cores 3 and to isolate the cable core 3 from the outer waterproof layer 5, which not only plays a role in fixing each cable core 3, but also can achieve a better waterproof effect for each cable core 3. The outer waterproof layer 5 and the inner waterproof layer 6 work together to effectively block the moisture outside the computer cable, improve the waterproof performance of the computer cable, better protect the electrical performance of the computer cable, reduce the probability of short circuit, and improve the safety of the computer cable.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
