Coaxial power cable

Abstract

This disclosure relates to the field of cable technology. One embodiment of this disclosure provides a coaxial power cable, comprising: an outer sheath, a center conductor, and a pair of concentric conductors. Both the center conductor and the concentric conductors are disposed within the outer sheath. An anti-bending component is disposed inside the outer sheath, an outer frame is disposed outside the outer sheath, and an anti-breakage fixing component is disposed on the outer sheath and the outer frame. The anti-bending component includes a shielding layer that wraps around the center conductor. A waterproof layer is fitted outside the shielding layer, and an inner filler frame is disposed outside the waterproof layer. This technical solution solves the technical problem in the prior art where two insulated cores are twisted together, resulting in a large gap between the insulated cores. This gap requires a large amount of filler material, leading to a large cable outer diameter and instability of the circular insulated core structure under external force, easily causing cable deformation.

Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of cable technology, and more specifically, to a coaxial power cable. Background Technology

[0002] Coaxial cable is a type of electrical wire and signal transmission line, generally made of four layers of material: the innermost layer is a conductive copper wire, the outside of which is surrounded by a layer of plastic (used as insulation and dielectric), the outside of which is a thin mesh conductive material (usually copper or alloy), and then the outermost insulating material is the outer sheath.

[0003] Coaxial cable can be used to transmit both analog and digital signals, making it suitable for a wide variety of applications, most notably cable television transmission, long-distance telephone transmission, short-distance connections between computer systems, and local area networks (LANs). Coaxial cable has developed rapidly as a means of transmitting television signals to households, leading to cable television. A cable television system can carry dozens or even hundreds of television channels, with a transmission range of tens of kilometers. For a long time, coaxial cable has been an important component of long-distance telephone networks. Today, it faces increasingly fierce competition from fiber optics, terrestrial microwave, and satellite.

[0004] Modern coaxial cables have two insulated cores twisted together, with a large gap between them. This gap requires a lot of filler material, resulting in a large outer diameter of the cable. When subjected to external forces, the circular insulated core structure of the cable is unstable and easily causes the cable structure to deform.

[0005] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a coaxial power cable, which solves the technical problem in the prior art where two insulated cores are twisted together, the gap between the insulated cores is large, and a lot of filler material is needed to fill the gaps, resulting in a large outer diameter of the cable and instability of the circular insulated core structure when the cable is subjected to external force, which easily causes the cable structure to deform.

[0007] According to one aspect, at least one embodiment of this disclosure provides a coaxial power cable, comprising:

[0008] An outer skin layer, a central conductor, and a pair of concentric conductors, wherein the central conductor and the concentric conductors are both disposed in the outer skin layer;

[0009] A bending-resistant component, wherein the bending-resistant component is disposed inside the outer skin layer;

[0010] The outer frame and the anti-breakage fixing components are provided, wherein the outer frame is disposed outside the outer skin layer, and the anti-breakage fixing components are disposed on the outer skin layer and the outer frame;

[0011] The bending-resistant component includes a shielding layer that wraps around the central conductor, a waterproof layer that is fitted over the shielding layer, and an inner filler frame that is provided outside the waterproof layer.

[0012] As a further technical solution, a number of soft rubber pads are provided between the waterproof layer and the inner filling frame, the concentric conductors are located on both sides of the surface of the inner filling frame, and a support strip and a pair of buffer pads are provided inside the outer skin layer.

[0013] As a further technical solution, the anti-breakage fixing component includes a pair of outer convex layers, each of which is disposed on the surface of the outer skin layer. A metal sheet is disposed inside the outer convex layer, and a pair of clamps are disposed on the surface of the outer frame.

[0014] As a further technical solution, the surface of the clamping plate is provided with a pin, which is inserted into the outer convex layer and the metal sheet. The side surface of the outer frame is provided with a pad, which is attached to the outer surface of the outer skin layer. Fixing holes are provided at both the upper and lower ends of the outer frame surface.

[0015] As a further technical solution, both the support bar and the inner filling frame are made of plastic, and the support bar has a hollow structure.

[0016] As a further technical solution, the fixed hole countersunk structure.

[0017] As a further technical solution, the cushioning pad adopts a sponge material structure.

[0018] As a further technical solution, the pair of clamps and the outer frame are integrally U-shaped.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0033] like Figures 1-3 As shown, a coaxial power cable according to an embodiment of the present disclosure is illustrated, comprising:

[0034] The outer skin layer 1, the central conductor 2, and a pair of concentric conductors 3 are both disposed in the outer skin layer 1;

[0035] Bending resistance component 5 is disposed inside the outer skin layer 1;

[0036] The outer frame 4 and the anti-breakage fixing component 6 are provided. The outer frame 4 is set outside the outer skin layer 1, and the anti-breakage fixing component 6 is set on the outer skin layer 1 and the outer frame 4.

[0037] The anti-bending component 5 includes a shielding layer 5-1, which wraps around the center conductor 2. A waterproof layer 5-2 is fitted outside the shielding layer 5-1. An inner filling frame 5-3 is provided outside the waterproof layer 5-2. Several soft rubber pads 5-4 are provided between the waterproof layer 5-2 and the inner filling frame 5-3. The concentric conductor 3 is located on both sides of the surface of the inner filling frame 5-3. A support strip 5-5 and a pair of buffer pads 5-6 are provided inside the outer skin layer 1.

[0038] In some examples, to achieve the effect of resisting bending deformation, an anti-bending component 5 is designed. A shielding layer 5-1 and a waterproof layer 5-2 are wrapped around the outside of the central conductor 2 for shielding and waterproofing. An inner filling frame 5-3 is also fitted on the outside. Several soft rubber pads 5-4 are set between the inner filling frame 5-3 and the waterproof layer 5-2. When bent, it can resist deformation and prevent right-angle bending. It can protect the central conductor 2 and the concentric conductor 3. Support strips 5-5 and two buffer pads 5-6 are also provided to provide support and enhance the anti-compression effect.

[0039] like Figures 1-3 As shown, this embodiment proposes an anti-breakage fixing component 6 including an outer convex layer 6-1, the outer convex layer 6-1 being disposed on the surface of the outer skin layer 1, a metal sheet 6-2 being disposed inside the outer convex layer 6-1, a pair of clamping plates 6-3 being disposed on the surface of the outer frame 4, pins 6-4 being disposed on the surface of the clamping plates 6-3, the pins 6-4 being inserted into the outer convex layer 6-1 and the metal sheet 6-2, a pad 6-5 being disposed on the side surface of the outer frame 4, the pad 6-5 being attached to the outer surface of the outer skin layer 1, and fixing holes 6-6 being opened at both the upper and lower ends of the surface of the outer frame 4.

[0040] In some examples, to achieve both tensile strength and easy fixation, a breakage-resistant fixing component 6 is designed. Two upwardly protruding outer layers 6-1 are provided on the surface of the outer sheath 1, and a metal sheet 6-2 is provided inside. The outer layers 6-1 increase the wear resistance, and the metal sheet 6-2 increases the tensile strength. Two clamping plates 6-3 are provided on the surface of the outer frame 4, and pins 6-4 are provided on the surface of the clamping plates 6-3. The clamping plates 6-3 can clamp the cable in the middle, and the pins 6-4 are inserted into the outer layers 6-1 and the metal sheet 6-2 to increase the gripping strength and facilitate the fixation of the cable. A pad 6-5 is also provided on the side surface of the outer frame 4. The pad 6-5 fits against the surface of the outer sheath 1 to increase the stability.

[0041] For example, such as Figure 3 As shown, both the support bar 5-5 and the inner filling frame 5-3 are made of plastic, and the support bar has a hollow structure.

[0042] In some examples, the plastic material has relatively high rigidity and is less likely to be bent at a 90° angle.

[0043] For example, such as Figure 2 As shown, the fixing hole has a countersunk structure at position 6-6.

[0044] In some examples, the fastener can be retracted into the fixing hole 6-6 by means of a countersunk structure.

[0045] For example, such as Figure 3 As shown, the cushioning pads 5-6 are made of sponge material.

[0046] In some examples, sponge material is used to fill the cable without affecting its normal bending.

[0047] For example, such as Figure 3 As shown, the pair of clamping plates 6-3 and the outer frame 4 form a U-shaped structure.

[0048] In some examples, a U-shaped structure is used to clamp the cable more snugly in the middle.

[0049] When needed, attach the outer frame 4 to the wall or other installation surface, fix the fasteners through the fixing holes 6-6, open the two clamps 6-3, put the cable between the clamps 6-3, loosen the clamps 6-3, the pins 6-4 on the surface of the clamps 6-3 will be inserted into the outer protrusion 6-1, and press hard to make the pins 6-4 pass through the metal plate 6-2 to complete the fixation.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
