Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a coaxial cable. Background Technology

[0002] Coaxial cable is a high-frequency signal transmission medium composed of multiple layers. Its core feature is that the inner and outer conductors are arranged coaxially. It is usually composed of a center conductor, an insulation layer, a shielding layer, and an outer sheath. It has the advantages of strong anti-interference ability, high bandwidth and long-distance transmission, as well as impedance matching and low loss.

[0003] To prevent the cable from shifting due to external personnel or other factors after installation, thus increasing the risk of damage, utility model patent CN222051412U discloses a coaxial cable. Although the above solution can fix and protect the cable body by using a base with multiple positioning frames, when actually installing multiple positioning frames on the base, it is necessary to first move the sliders at both ends of the positioning frame through the mounting port at one end of the base to the inside of the groove, and then continuously move the positioning frame to the corresponding position on the outside of the cable. However, after the slider enters the inside of the groove, the inside of the positioning frame will be in contact with the cable surface. Therefore, when adjusting the position of the positioning frame, the positioning frame will continuously rub against the cable surface, making the actual adjustment too inconvenient and affecting the installation efficiency.

[0004] Therefore, it is necessary to invent a coaxial cable to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a coaxial cable that allows for more convenient fixation of the coaxial cable body using multiple sets of cable positioning components. This makes it easier to use and increases installation efficiency. Furthermore, the M-shaped positioning component, integrally formed from an arc-shaped clamping part, two V-shaped deformation parts, and two plug-in parts, is easy to manufacture and has low production costs. This addresses the problem mentioned in the background art where, when installing multiple positioning frames on a base, the sliders at both ends of the positioning frame need to be moved through the mounting port at one end of the base to the inside of the groove, and then the positioning frame needs to be continuously moved to the corresponding position on the outside of the cable. However, after the slider enters the groove, the inside of the positioning frame will adhere to the cable surface. Therefore, when adjusting the position of the positioning frame, the positioning frame will continuously rub against the cable surface, making actual adjustment inconvenient and affecting installation efficiency.

[0006] According to one aspect of this disclosure, the following technical solution is provided: a coaxial cable, comprising:

[0007] A wall-mounted fixing mechanism, which provides an installation base for multiple sets of cable positioning assemblies;

[0008] Multiple sets of cable positioning assemblies, each set including an M-shaped positioning element and two U-shaped clamps, wherein the M-shaped positioning element includes an arc-shaped clamping part, both ends of which are provided with V-shaped deformation parts, and the end of the V-shaped deformation part away from the arc-shaped clamping part is provided with a plug-in part adapted to the adjacent U-shaped clamp; and

[0009] The coaxial cable body is used to transmit electrical signals.

[0010] According to at least one embodiment of the coaxial cable of the present disclosure, the wall fixing mechanism includes a fixing base, and the fixing base has a plurality of evenly distributed fixing holes on both sides of its top.

[0011] According to at least one embodiment of the coaxial cable disclosed herein, the top of the fixing base is provided with a cable positioning groove adapted to the coaxial cable body, and the bottom of the fixing base is provided with a weight reduction groove.

[0012] According to at least one embodiment of the coaxial cable of this disclosure, the fixing base, cable positioning groove, weight reduction groove and multiple U-shaped clamps are integrally formed, and the arc-shaped pressing part, two V-shaped deformation parts and two plug-in parts are integrally formed.

[0013] According to at least one embodiment of the coaxial cable disclosed herein, the coaxial cable body includes a central conductor made of copper alloy, and an insulating layer made of polyethylene is fixedly sleeved on the outside of the central conductor.

[0014] According to at least one embodiment of the coaxial cable of the present disclosure, a shielding layer made of metal braided mesh is fixedly sleeved on the outside of the insulation layer, and an outer sheath made of PVC is fixedly sleeved on the outside of the shielding layer.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention features a cable positioning assembly to facilitate the installation of a fixing base on a wall. The coaxial cable body is then placed inside the cable positioning groove for positioning. The M-shaped positioning piece is then removed, and the index finger and thumb gently press the two V-shaped deformation parts towards each other. This causes the two V-shaped deformation parts to deform inwards, simultaneously bringing the two plug-in parts closer together. The M-shaped positioning piece is then held in its current state, with the arc-shaped clamping part pressed against the outside of the coaxial cable body. The ends of the two plug-in parts are then aligned with the two adjacent U-shaped clamps. The pressure on the two V-shaped deformation parts is then released, allowing the restored V-shaped deformation parts to insert the two plug-in parts into the adjacent U-shaped clamps for fixation. Compared to existing technologies, this invention allows for more convenient fixation of the coaxial cable body using multiple cable positioning assemblies, offering greater ease of use and higher installation efficiency. Furthermore, the M-shaped positioning piece, integrally formed from the arc-shaped clamping part, the two V-shaped deformation parts, and the two plug-in parts, is easy to manufacture and has lower production costs.

[0025] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 1 This is a schematic diagram of the overall structure of a coaxial cable according to one embodiment of the present disclosure.

[0027] Figure 2 This is a schematic diagram of the wall-mounted fixing mechanism 1, cable positioning assembly 2, and coaxial cable body 3 of a coaxial cable according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the cable positioning assembly 2 of a coaxial cable according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the coaxial cable disclosed herein consists of three parts: a wall-mounted fixing mechanism 1, multiple sets of cable positioning components 2, and a coaxial cable body 3. The three parts work together to achieve stable cable fixing, efficient signal transmission, and convenient installation. The wall-mounted fixing mechanism 1 provides the installation foundation for the whole, the cable positioning components 2 are responsible for accurately fixing the coaxial cable body 3 to the wall-mounted fixing mechanism, and the coaxial cable body 3 undertakes the function of transmitting electrical signals (especially high-frequency signals).

[0030] like Figure 2As shown in this disclosure, the wall-mounted fixing mechanism 1 includes a fixing base 11. Multiple evenly distributed fixing holes 12 are provided on both sides of the top of the fixing base 11. The hole diameter is designed to be φ6mm-φ8mm, suitable for M5-M6 expansion bolts or self-tapping screws. The spacing between the fixing holes is set to 15cm-20cm to ensure uniform force distribution when the fixing base 11 is connected to the wall, avoiding deformation of the base due to localized stress concentration. During installation, only drilling holes in the wall at corresponding positions using an impact drill, inserting expansion tubes, and then tightening the bolts through the fixing holes 12 are required to complete the installation of the fixing base 11. No professional or complex tools are needed. The top of the fixing base 11 has a cable positioning groove 13 adapted to the coaxial cable body 3, which can pre-position the coaxial cable body. No additional position adjustment is needed when placing the cable, ensuring that the cable axis remains parallel to the fixing base 11 and avoiding subsequent fixing deviations caused by cable offset. The fixed base 11 has a weight-reducing groove 14 at its bottom. The fixed base 11, cable positioning groove 13, weight-reducing groove 14 and multiple U-shaped clamps 22 are integrally formed. The fixed base 11 and U-shaped clamps 22 are made of engineering plastic or lightweight aluminum alloy, which has both mechanical strength and corrosion resistance. Engineering plastic is suitable for dry indoor environments, such as building monitoring cabling and indoor cable TV cabling, while aluminum alloy is suitable for outdoor or humid environments, such as outdoor base station signal transmission. It effectively avoids rust or deformation during long-term use. If engineering plastic is used, it is produced using an integrated injection molding process. If aluminum alloy is used, it is produced using an extrusion molding process. Compared with the traditional multi-part splicing structure, the integral molding can avoid structural weak points caused by splicing gaps, improve overall stability, and eliminate the component assembly process, increasing production efficiency by more than 50% and reducing installation problems caused by component mismatch errors.

[0031] Therefore, the bottom of the fixing base 11 can be attached to the wall, and then the fixing bolts can be passed through multiple fixing holes 12 to fix the fixing base 11 to the wall. The cable positioning groove 13 can accommodate and position the matching coaxial cable body 3. The weight reduction groove 14 can reduce the overall weight and material usage of the wall fixing mechanism 1, making it convenient to use and reducing production costs. The integral molding of the fixing base 11, cable positioning groove 13, weight reduction groove 14 and multiple U-shaped clamps 22 can further reduce production difficulty and cost.

[0032] like Figure 2 and Figure 3As shown, in a preferred embodiment, any set of cable positioning components 2 includes an M-shaped positioning element 21 and two U-shaped clamps 22. The M-shaped positioning element 21 includes an arc-shaped pressing part 23. Both ends of the arc-shaped pressing part 23 are provided with V-shaped deformation parts 24. The end of the V-shaped deformation part 24 away from the arc-shaped pressing part 23 is provided with a plug-in part 25 that is adapted to the adjacent U-shaped clamp 22. The M-shaped positioning element 21 is made of elastic plastic, such as PP polypropylene or TPU thermoplastic polyurethane, which has good deformation recovery ability. It can produce slight deformation when pressed and quickly recovers after being released. It is not easy to develop deformation fatigue after long-term use. Its overall structure is integrally injection molded from the arc-shaped pressing part 21, the two V-shaped deformation parts 22 and the two plug-in parts 23.

[0033] Therefore, to facilitate the installation of the fixing base 11 on the wall, the coaxial cable body 3 is placed inside the cable positioning groove 13 for positioning. At this time, the M-shaped positioning piece 21 is picked up, and then the index finger and thumb are used to gently press the two V-shaped deformation parts 24 towards each other. At this time, the two V-shaped deformation parts 24 deform inward, which simultaneously drives the two plug parts 25 to move closer to each other. Then, the M-shaped positioning piece 21 is kept in its current state and the arc-shaped pressing part 23 is attached to the outside of the coaxial cable body 3. Then, the ends of the two plug parts 25 are... Align the two adjacent U-shaped clamps 22, and then release the pressure on the two V-shaped deformation parts 24. At this time, the two restored V-shaped deformation parts 24 drive the two plug-in parts 25 to insert into the inner side of the adjacent U-shaped clamps 22 to achieve fixation. Compared with the existing technology, it is more convenient to use multiple sets of cable positioning components 2 to complete the fixation of the coaxial cable body 3. It is easy to use and has higher installation efficiency. In addition, the M-shaped positioning part 21, which is integrally formed by the arc-shaped clamping part 23, the two V-shaped deformation parts 24 and the two plug-in parts 25, is easy to produce and has a low production cost.

[0034] like Figure 2 As shown in this disclosure, the coaxial cable body 3 includes a center conductor 31 made of high-purity copper alloy, which is responsible for transmitting electrical signals. An insulation layer 32 made of high-density polyethylene is fixedly sleeved on the outside of the center conductor 31 to isolate the inner and outer conductors and maintain signal stability. A shielding layer 33 made of metal braided mesh is fixedly sleeved on the outside of the insulation layer 32 to effectively block external electromagnetic interference and prevent signal leakage. An outer sheath 34 made of PVC is fixedly sleeved on the outside of the shielding layer 33 to enhance mechanical strength and weather resistance.

[0035] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0036] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
