Description

A parallel cable with a waterproof coaxial shielding layer Technical Field

[0001] This invention relates to the field of cable waterproofing technology, and more particularly to a parallel structure cable with a waterproof coaxial shielding layer. Background Technology

[0002] Existing methods for waterproofing coaxial cables generally involve manually applying adhesive to both ends of the cable for sealing. However, manual application is inefficient, and the adhesive is difficult to penetrate evenly, which may result in localized hardening or air leakage, leading to poor sealing. In addition, the cables are mostly used outdoors, where they are affected by extreme heat and cold, causing the outer sheath of the cable to expand and contract easily and crack. Under these circumstances, moisture can easily enter the cable, reducing its service life. Therefore, it is necessary to design a coaxial cable that is waterproof from its own structure. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the above-mentioned technology and provide a parallel-structure cable with a waterproof coaxial shielding layer, thereby solving the technical problem of self-waterproofing of the coaxial shielding layer. To solve the above-mentioned technical problems, this invention adopts the following technical solution:

[0004] A parallel cable with a waterproof coaxial shield is provided, wherein: after two coaxial cables are arranged side by side in parallel, an integral sheath layer is formed by uniformly extruding polyvinyl chloride on the outside; characterized in that: each coaxial cable includes a coaxial conductor, coaxial insulation, coaxial shield, and an outer sheath; the coaxial conductor and coaxial shield are coated with adhesive to form a waterproof protective layer, thereby ensuring the waterproof effect of the coaxial shield layer.

[0005] In this embodiment, it is preferred that the coaxial cable has two, but not limited to two, lines arranged side by side in parallel.

[0006] In this embodiment, the coaxial cable preferably includes, from the inside out, a coaxial cable conductor, a coaxial cable insulation layer, a winding layer, and an outer sheath.

[0007] In this embodiment, it is preferable that the coaxial conductor and the coaxial shield are coated with an adhesive to form a waterproof protective layer, thereby ensuring the waterproof effect of the coaxial shield layer.

[0008] In this embodiment, it is preferred that the conductor is not limited to tin-plated copper, and the winding layer is not limited to tin-plated copper or nickel-plated copper. Attached Figure Description

[0011] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0012] It should be understood that, when used in this specification and the appended claims, the term "comprising" indicates the presence of a descriptive feature, integral, step, operation, element, and / or component, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or sets.

[0013] To keep the drawings concise, only the parts relevant to the invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of components with the same structure or function is shown schematically, or only one is labeled. In this document, "one" can mean not only "only one" but also "more than one".

[0014] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0015] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of the invention are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the description of the positions of these components changes, these directional indications also change accordingly.

[0016] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0018] In this embodiment, as shown in Figure 1, a coaxial cable with a waterproof shielding layer (hereinafter referred to as "cable") is provided, which includes a coaxial cable and another coaxial cable extruded and fused to form a parallel cable.

[0019] In this embodiment, as shown in Figure 1, the cable includes an outer sheath, a coaxial shield, a coaxial insulation layer, and a coaxial conductor. The outer sheath covers the coaxial shield, the coaxial shield covers the coaxial insulation layer, and the coaxial insulation layer covers the coaxial conductor. The coaxial conductor is formed by twisting multiple copper wires and has a polymer material attached to form a fusion layer (not shown). This fusion layer is located between the insulation layer 3 and the conductor 4, which helps maintain the bond between them and also facilitates the fusion and curing process. In this example, after the coaxial insulation layer 3 and the outer shield layer 2 are joined, adhesive (not shown) is applied to the surface of the shield layer 2 through a glue applicator's gluing tank. The adhesive cures on the surface of the shield layer 2, forming an outer sheath 1 that covers the outer edge of the shield layer, creating a seamless whole and effectively improving the cable's waterproof level.

[0020] In this embodiment, as shown in Figure 1, the shielding layer 2 is a mesh shielding layer formed by the metal wire and the outer periphery of the coaxial insulating layer 3. The shielding layer has a shielding function and can effectively improve product performance.

[0021] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0022] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention.
