Description

Technical Field

[0001] This utility model relates to the field of communication cable technology, specifically a cold-resistant, waterproof, and interference-resistant communication cable. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, typically composed of several or groups of conductors. It is usually a rope-like cable made up of several or groups of conductors (each group containing at least two conductors) twisted together, with each group of conductors insulated from each other and often twisted around a central conductor. The entire cable is covered with a highly insulating outer layer. Cables are characterized by being internally energized and externally insulated.

[0003] An existing patent (publication number: CN216053987U) discloses a communication cable in which a waterproof sleeve is fitted on the outer wall of a tensile sleeve. The waterproof sleeve is made of a waterproof material, which blocks water from entering the outer wall of the tensile sleeve. The waterproof sleeve has multiple dehumidification tubes arranged along its axial direction. The walls of the dehumidification tubes have capillary tubes and water outlets that extend out of the outer wall of the waterproof sleeve. The water outlets are connected to valves. Some water vapor may enter the cable from the outside. Since the waterproof sleeve has blocked the water, the water vapor may be stored inside the waterproof sleeve. At this time, the water droplets located inside the waterproof sleeve can be extracted through the water outlets, thereby keeping the overall dryness of the cable.

[0004] To address the aforementioned issues, while existing patents offer solutions that can achieve waterproofing through the use of components such as tensile sleeves, the actual environmental conditions in which cables operate vary greatly. In environments with low temperatures, the cables may be affected. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1:

[0030] Please see Figures 1-3 This is the first embodiment of the present utility model.

[0031] This embodiment provides a cold-resistant, waterproof, and interference-resistant communication cable, including a cable core 1, a protective inner shell 2, a silicone protective sleeve 3, and a polyethylene protective sleeve 4. The protective inner shell 2 is fitted over the cable core 1, the silicone protective sleeve 3 is fitted over the protective inner shell 2, and the polyethylene protective sleeve 4 is fitted over the silicone protective sleeve 3; it also includes:

[0032] The protective mechanism 5 is located inside the polyethylene protective sleeve 4, and the protective mechanism 6 is located outside the polyethylene protective sleeve 4.

[0033] Specifically, the protective mechanism 5 includes a glass fiber filling layer 501, which is embedded inside the silicone protective sleeve 3, and a woven protective layer 502 is embedded between the silicone protective sleeve 3 and the polyethylene protective sleeve 4.

[0034] Furthermore, the glass fiber filling layer 501 effectively provides electrical and thermal insulation, as well as electromagnetic shielding and heat preservation. The woven protective layer 502, made of waterproof polyether material and Kevlar woven structure, provides waterproof and cold-resistant effects.

[0035] Specifically, the inner wall of the protective inner shell 2 is fitted with a braided shielding layer 503, the inside of the braided shielding layer 503 is fitted with a conductive layer 504, and a metal foil 505 is fixedly installed on the outer wall of the protective inner shell 2 facing the cable core 1.

[0036] Furthermore, the braided shielding layer 503 is formed into a mesh structure layer by braiding metal wires (such as copper wire, aluminum wire, tin-plated copper wire, etc.) through a braiding process, and is wrapped around the core wire or insulation layer. Its core function is to block electromagnetic interference (EMI) and radio frequency interference (RFI), while reducing its own signal interference to the outside world.

[0037] Specifically, the braided shielding layer 503 is tightly bonded to the conductive layer 504, and the braided shielding layer 503 is tightly bonded to the protective inner shell 2.

[0038] Furthermore, the conductive layer 504 is formed by incorporating conductive particles (such as carbon black or metal powder) into the plastic to create a conductive shielding layer, which has low overall cost and is easy to process.

[0039] In use, the cable core 1 is first protected by a rubber inner shell 2 to prevent mutual interference. At the same time, it is combined with a braided shielding layer 503, a conductive layer 504 and a metal foil 505 to effectively protect the cable core 1 while providing anti-electromagnetic interference. Meanwhile, a glass fiber filling layer 501 is filled inside the silicone protective sleeve 3, and a silicone protective sleeve 3, a polyethylene protective sleeve 4 and a braided protective layer 502 are placed on the outside to provide protection while also providing waterproof and cold-resistant effects.

[0040] In summary, the external silicone protective sleeve 3 and polyethylene protective sleeve 4 provide cold and waterproof protection, while the internal braided shielding layer 503, conductive layer 504 and metal foil 505 provide electromagnetic interference protection. This gives the entire communication cable cold-resistant, waterproof and interference-resistant properties, making it suitable for harsh and cold regions.

[0041] Example 2:

[0042] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present utility model.

[0043] Specifically, the protective mechanism 6 includes a fixing ring 601, which is fixedly installed on the outside of the polyethylene protective sleeve 4, and a sleeve plate 602 is sleeved on one side of the fixing ring 601 outside the polyethylene protective sleeve 4.

[0044] Furthermore, the fixing ring 601 limits and engages, preventing the sleeve plate 602 from falling off the polyethylene protective sleeve 4.

[0045] Specifically, a PVC film 604 is fixedly installed on one side of the sleeve plate 602, and a rubber pad 603 is embedded inside the sleeve plate 602.

[0046] Furthermore, the rubber pad 603 facilitates the compression of the reserved space, allowing the sleeve plate 602 to be fitted through the fixing ring 601, and the two sleeve plates 602 to be separated from each other, thus stretching the PVC film 604.

[0047] Specifically, the PVC membrane 604 has reinforcing ribs 605 embedded inside, and Oxford cloth 606 is fixedly installed on the inner wall of the PVC membrane 604.

[0048] Furthermore, the PVC film 604 has internal reinforcing ribs 605 to prevent wrinkles, and together with the Oxford cloth 606, it has a certain tensile strength.

[0049] Specifically, an insulation filling layer 607 is fixedly installed at the bottom of the Oxford cloth 606, and a thickening layer 608 is fixedly installed at the bottom of the insulation filling layer 607.

[0050] Furthermore, the insulation effect is further improved by the insulation filling layer 607, and the strength of the PVC film 604 is improved by the thickened layer 608 made of the same material as PVC.

[0051] In use, the sleeve plate 602 passes through the fixed ring 601 through the space reserved by the rubber pad 603, so that the two sleeve plates 602 stretch the PVC film 604. The overall strength is improved by the reinforcing rib 605 and the thickened layer 608, and the tensile effect is improved by the Oxford cloth 606. At the same time, the protective effect is further improved by the heat insulation filling layer 607.

[0052] In summary, by stretching and sliding the sleeve plate 602, the PVC film 604 can be unfolded to provide overall protection for the cable, and in conjunction with the Oxford cloth 606, the thermal insulation filling layer 607 and the thickened layer 608, the protection and insulation effects are further improved.
