Description

Technical Field

[0001] This utility model relates to the field of optical fiber cable technology, and in particular to an anti-interference optical fiber cable. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, typically composed of several or more conductors. Cables are classified into various categories, all consisting of single or multiple strands of conductors and insulation layers, used to connect circuits, electrical appliances, etc. Usually, multiple sets of wires are housed within the protective sheath of a single cable.

[0003] Existing cables contain multiple cores that are typically in contact with each other, leading to interference and affecting their performance. Furthermore, excessive current in the cable results in poor heat dissipation, impacting its lifespan. Therefore, we propose an anti-interference fiber optic cable. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing cables, which have multiple cores inside and are generally placed in contact with each other, causing interference between the cables and affecting their performance. In addition, when the current in the cable is too high, the internal heat dissipation effect is low, which affects the service life of the cable. Therefore, an anti-interference fiber optic cable is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-interference fiber optic cable includes a reinforced sheath and four cores. The four cores are located inside the reinforced sheath, and an anti-interference structure and a heat dissipation mechanism are provided between the four cores. An insulating sleeve is provided inside the reinforced sheath, and a shielding layer is provided inside the insulating sleeve.

[0007] Preferably, the anti-interference structure includes a cross-shaped isolation frame, with the four wire cores located in the gaps between the cross-shaped isolation frame.

[0008] Preferably, a protective isolation layer is provided on the outside of the wire core, and an anti-interference layer is provided on the outside of the cross isolation frame.

[0009] Preferably, the inner side of the cross-shaped isolation frame is provided with a guide hole, and multiple heat dissipation holes are provided on the inner walls of both sides of the guide hole.

[0010] Preferably, a protective layer is provided on the inner side of the guide hole.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] (1) This solution uses a cross-shaped isolation frame to fully isolate the four wire cores, thereby increasing the distance between the four wire cores and reducing mutual interference between the wire cores.

[0013] (2) Due to the setting of guide holes and heat dissipation holes on the cross isolation frame, the heat accumulated by the four wire cores after long-term use is dissipated, reducing the aging of each isolation and protective layer under high temperature.

[0014] This invention has a simple structure and is easy to use. It can increase the distance between the wire cores and reduce mutual interference. At the same time, it can effectively reduce the temperature of the wire cores and reduce the aging of each isolation and protective layer under high temperature. Attached Figure Description

[0019] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, and not all embodiments.

[0020] Example

[0021] Reference Figure 1-3 An anti-interference fiber optic cable includes a reinforced sheath 1 and four cores 4. The four cores 4 are located inside the reinforced sheath 1. An anti-interference structure is provided between the four cores 4, and a heat dissipation mechanism is provided between the four cores 4. An insulating sleeve 2 is provided inside the reinforced sheath 1, and a shielding layer 3 is provided inside the insulating sleeve 2.

[0022] In this embodiment, the anti-interference structure includes a cross-shaped isolation frame 5, with four wire cores 4 located in the gaps of the cross-shaped isolation frame 5. A protective isolation layer 6 is sleeved on the outside of the wire cores 4, and an anti-interference layer 9 is provided on the outside of the cross-shaped isolation frame 5. The cross-shaped isolation frame 5 enables sufficient isolation between the four wire cores 4, thereby increasing the distance between the four wire cores, and reducing mutual interference between the wire cores under the action of the anti-interference layer 9.

[0023] In this embodiment, the inner side of the cross-shaped isolation frame 5 is provided with a guide hole 7, and multiple heat dissipation holes 10 are provided on both sides of the inner wall of the guide hole 7. The inner side of the guide hole 7 is provided with a protective layer 8. The arrangement of the guide hole 7 and the heat dissipation holes 10 on the cross-shaped isolation frame 5 can facilitate heat dissipation operations at various positions of the wire core 4 and reduce the effect of accelerated aging of each isolation and protective layer under high temperature.

[0024] Working principle: The reinforced sheath 1 facilitates the isolation and protection of the wire core 4, and the insulating sleeve 2 and shielding layer 3 provide insulation and shielding against the outside world. At the same time, the cross isolation frame 5 ensures that the four wire cores 4 are fully isolated, thereby increasing the distance between the four wire cores. Under the action of the anti-interference layer 9, the mutual interference between the wire cores is reduced. The guide holes 7 and heat dissipation holes 10 on the cross isolation frame 5 facilitate heat dissipation at various positions of the wire core 4, reducing the aging effect of each isolation and protective layer under high temperature.

[0025] All structural shapes, sizes, and materials included in Embodiment 1 in this application can be selected and adjusted to meet specific usage needs. The accompanying drawings are schematic structural diagrams, and the actual dimensions can be appropriately adjusted.
