SUPPORT BRACKET FOR FIXING CABLESTECHNICAL FIELD
[0001] The present disclosure relates to the field of mechanics, particularly to a support bracket for fixing cables.BACKGROUND
[0002] In the field of power transmission, cables play a crucial role as a key component connecting power generation facilities to the power grid. Especially in the field of renewable energy such as wind power generation, the use of cables is indispensable. However, when transmitting electrical energy, the electromagnetic force generated by the current passing through the cables can cause the cables to vibrate and swing, which not only affects the stability of the cables but also poses a threat to the surrounding environment and personnel safety. Therefore, developing a bracket system that can effectively fix the cables and reduce vibration is of great significance for ensuring the safety and reliability of power transmission.
[0003] In places where cables are densely arranged, such as power transmission stations or substations, the interaction force between cables becomes particularly significant when current passes through. Especially in extreme cases such as short circuits, the repulsive force between cables may increase sharply, increasing safety risks. Traditional cable fixing methods often use physical bundling to achieve fixation, but this method can cause cables to bear greater mechanical stress when the cable density increases, exacerbating the cables' response to short circuits. In addition, the tight arrangement of cables will reduce their heat dissipation area, reducing the efficiency of heat dissipation, which may lead to an increase in cable temperature during long-term operation, increasing resistance, affecting the efficiency of electrical energy transmission, and increasing operating costs.
[0004] Cables will experience thermal expansion and contraction during operation due to temperature changes, which will cause additional stress at the fixing points. This repeated stress may cause the fixing device to fatigue and even damage, thereby reducing the safety and reliability of the fixing device in emergencies such as short circuits.
[0005] For cables used in high-voltage environments, due to their large volume and weight, the installation and maintenance work becomes complicated and dangerous. For example, cables with a larger diameter may weigh more than tens of kilograms per meter, which requires great care during installation to avoid causing harm to workers or equipment damage.SUMMARY
[0006] As mentioned above, there are many shortcomings in the cable fixing brackets in the existing technology, especially in terms of safety, stability, heat dissipation efficiency, and the convenience of installation and maintenance. Therefore, it is necessary to develop a new type of cable bracket system to solve the above problems and improve the performance and safety of cables under various working conditions. This system needs to be able to adapt to the cable fixing needs under different environmental conditions, while reducing electromagnetic interference between cables, and improving the efficiency and reliability of power transmission.
[0007] The object of the present disclosure is to overcome the disadvantages of the related technology and provide an improved support bracket for fixing cables.
[0008] The present disclosure provides a support bracket for fixing cables. The bracket includes a frame assembly, a spacing assembly, and an installation base. The spacing assembly is installed on one side of the installation base, for example, in high-voltage power transmission scenarios, for spacing apart the power transmission cables. The frame assembly can be movably coupled to the installation base via a coupling device, enabling the frame assembly to have at least a fully open state and a closed state. The coupling device can be configured to allow the frame assembly to stay (e.g., hold) in any posture (e.g., position) between the fully open state and the closed state, for example, forming and maintaining different angles with the installation base, to facilitate easily pre-binding the cables to the appropriate position. In the fully open state, the spacing assembly does not contact the frame assembly. Thereby, the spacing assembly can be as exposed as possible without being obscured, providing a larger space for arranging cables and facilitating the placement of cables into the bracket. In the closed state, the spacing assembly abuts the frame assembly to form at least one aperture for the cable to pass through.
[0009] This technical solution provides a support bracket for fixing cables, achieving flexibility and convenience through the movable coupling of the frame assembly and the installation base, allowing the frame assembly to switch between the fully open state and the closed state, facilitating the installation and maintenance of cables. In the fully open state, the spacing assembly does not contact the frame assembly, facilitating the placement or removal of cables; in the closed state, the spacing assembly abuts the frame assembly to fix the cables, ensuring stability and reducing vibration, enhancing safety. The design of the bracket helps reduce the swing and vibration of cables caused by electromagnetic forces, reducing the risk of cables causing harm to the surrounding environment and personnel during operation. Additionally, it is understood that the bracket, through the adjustable design of the spacing assembly and the frame assembly, can adapt to cables of different sizes and adjust the aperture according to changes in the number of cables, thereby increasing the versatility and adaptability of the bracket, making the bracket structure compact and suitable for installation in limited spaces. Overall, the bracket design proposed in the present disclosure improves the stability and safety of cables, simplifies maintenance work, and enhances the reliability and efficiency of power transmission.
[0010] According to one possible embodiment, the frame assembly includes two arms, which are shaped such that when they rotate towards each other via the coupling device to achieve the closed state, the two arms and the installation base together form a rounded, closed shape when viewed from a direction perpendicular to the plane of rotation. By designing the frame assembly to include two rotatable arms, an adjustable closure mechanism is achieved. When these two arms rotate towards each other via the coupling device to the closed state, they form a structure that presents a rounded, closed shape when viewed from a direction perpendicular to the plane of rotation. This design not only provides a sturdy solution for cable fixation but also enhances the structural integrity and aesthetics of the bracket, potentially reducing the risk of damage to power facilities caused by sharp edges of the bracket, enhancing overall safety and practicality.
[0011] According to one possible embodiment, the coupling device includes two rotatable members, each arm corresponding to one rotatable member. The rotatable member is located at a first end of the arm and is movably coupled to the installation base. By integrating the rotatable member at the first end of each arm, a movable coupling between the arm and the installation base is achieved, providing a highly flexible bracket structure. As used herein, the term "movably coupled" means that one end of the arm is connected to the installation base via a rotatable member, allowing the arm to rotate relative to the base within a certain range. This design enables the bracket to adapt to cables of different sizes and shapes, while providing greater flexibility and operational space during installation and maintenance. The technical advantage lies in enhancing the adaptability and flexibility of the bracket, allowing the same bracket to be suitable for various cable configurations, while simplifying installation and maintenance work. Due to the flexibility of the movable coupling, it is easier to adjust and position the arms, reducing the need for precise alignment, thus saving time and labor.
[0012] According to one possible embodiment, the bracket proposed in the present disclosure also includes a locking device. In the closed state, the locking device tightens the two arms at their respective second ends. By adding a locking device, stable positioning of the two arms in the closed state is achieved. The locking device is located at the second end of the arm and can tighten them when the arms are closed, preventing relative displacement between the arms or allowing relative displacement within an allowable range to accommodate the swing caused by thermal expansion of the cables or electromagnetic forces during power transmission. Such a design improves the stability and safety of the bracket, ensuring that cables can be effectively fixed under various conditions, reducing cable damage caused by vibration or thermal expansion, and also simplifying the installation and maintenance of cables, as the locking device provides an adjustable tightening solution to meet the fixing needs of different cables.
[0013] According to one possible embodiment, the spacing assembly includes a plurality of support frames. Each of the plurality of support frames is connected to at least one other of the plurality of support frames via a connecting device. By making the spacing assembly include a plurality of support frames and connecting these frames via a connecting device, a flexible and expandable support structure is achieved. This design allows the spacing assembly to be adjusted and configured as needed to accommodate different numbers and sizes of cables, while providing enhanced stability and structural integrity. In this way, the bracket can evenly distribute the forces between cables, reducing stress concentration at individual connection points, thereby improving the durability and reliability of the entire cable fixing bracket. In addition to reducing interference between cables, this modular support frame design is also convenient for installation and maintenance, as each support frame can be adjusted or replaced independently without disassembling the entire spacing assembly, which is particularly useful during cable maintenance or upgrades.
[0014] According to one possible embodiment, the bracket proposed in the present disclosure also includes a fixing base and a sliding mechanism. The fixing base has fixing parts and a receiving part, with the fixing parts located at both ends of the receiving part, and the fixing parts being provided with installation holes. The receiving part is constructed such that the installation base is accommodated in the fixing base. The sliding mechanism is constructed such that the installation base can slide relative to the fixing base.
[0015] This technical solution integrates a fixing base and a sliding mechanism. The fixing base includes a fixing part and a receiving part, with the fixing parts located at both ends of the receiving part and being provided with installation holes, while the receiving part is designed such that the installation base is accommodated in the fixing base. The sliding mechanism allows the installation base to slide relative to the fixing base. This design enables the bracket to "passively" and flexibly adjust its position, for example, in a direction roughly perpendicular to the cable extension direction, to absorb the swing and vibration of the cables in the lateral direction perpendicular to their extension. As used herein, the term "accommodation" means that the receiving part is structurally designed to exactly match and accommodate the installation base, ensuring a secure yet adjustable fit between the two. The technical benefit is that this design provides convenience and flexibility during installation, allowing the bracket to adjust and fine-tune according to the swing caused by the cables when powered or transmitting electricity, achieving the best "soft" fixing effect. Additionally, the introduction of the sliding mechanism allows the installation base to smoothly move on the fixing base, quickly absorbing and counteracting cable swing, enhancing the safety of cable fixation and increasing the applicability and practicality of the bracket.
[0016] According to one possible embodiment, the sliding mechanism includes one or more limiting members and one or more waist-limiting holes. The installation base is provided with the limiting members, and the receiving part is provided with the waist-limiting holes. The limiting members correspondingly passes through the waist-limiting holes. Thereby, the sliding function of the installation base relative to the fixing base is achieved, and through the cooperation of the limiting member and the waist-limiting hole, the movement range of the installation base can be precisely controlled, i.e., "limited" . As used herein, the term "limited" means to restrict the displacement of an object within a certain range, which in this context means that the movement of the installation base is precisely controlled within the range of the waist-limiting hole, preventing excessive movement or unstable phenomena. The limiting function ensures that the bracket can securely fix the cables after adjusting to the appropriate position, avoiding excessive displacement caused by vibration or external forces, enhancing the stability and reliability of the bracket. Moreover, the limiting design also allows for fine-tuning while ensuring safety, adapting to cables of different sizes or cable layout adjustments, improving the flexibility and scope of the bracket.
[0017] According to one possible embodiment, the installation holes include a first waist-limiting installation hole and a second waist-limiting installation hole that are perpendicular to each other. As an example rather than a limitation, one of the fixing parts (e.g., the left fixing part) is provided with the first waist-limiting installation hole, and the other fixing part (e.g., the right fixing part) is provided with the second waist-limiting installation hole. By having the fixing parts of the fixing base equipped with the vertically arranged first and second waist-limiting installation holes, the bracket can adapt to the S-shaped arrangement of cables, allowing a single bracket to rotate as needed in the S-shaped cable layout, facilitating the flexible fixation of a plurality of brackets in the S-shaped cable layout. The support bracket disclosed in the present disclosure, with its first waist-limiting installation hole and second waist-limiting installation hole, allows for adjustable fixing of the bracket, such as rotation and sliding. The benefit of this configuration lies in that, through the provision of these waist-limiting holes, it enhances the bracket’s ability to adapt to changes in the position of the cables, ensuring the stability of the cables under the bracket’s adjustable fixed states, reducing stress concentration caused by changes in cable layout direction, while improving the installation flexibility and adaptability of the bracket. The setting of waist-limiting holes enables the bracket to adapt to the S-shaped cable layout, ensuring the neatness and stability of the cable layout and effectively simplifying the installation process, reducing operational intensity.
[0018] According to one possible embodiment, the connecting device includes pairs of protrusions and recesses provided on the installation end surface of the support frame. As an example rather than a limitation, the plurality of support frames include a lower support frame and two upper support frames. Internal threaded holes can be formed through the upper support frames, and nuts can be provided at the recesses of the lower support frame. Accordingly, the connecting device can also include a bolt that passes through the internal threaded hole and tightens to the nut to secure the upper support frame to the lower support frame.
[0019] According to one possible embodiment, each arm has at least an inner side equipped with a sheath. Thereby, it can effectively protect the cables from mechanical damage and environmental factors, such as wear, corrosion, or external impacts. The presence of the sheath not only enhances the durability of the cables but also helps maintain the insulating performance of the cables, reducing the risk of electrical failures. Additionally, the sheath can provide additional support, helping to fix the position of the cables and reducing the movement of the cables under force, thereby ensuring the stability and safety of power transmission.
[0020] According to one possible embodiment, the side of the installation base where the spacing assembly is installed is also provided with an insulating pad. The insulating pad is sandwiched between the spacing assembly and the installation base. Thereby, it can prevent electrical short circuits or accidental current conduction, enhancing the safety of the cable fixing system. The use of the insulating pad also helps reduce vibration and noise, protecting the cables from mechanical stress and environmental factors, thereby extending the service life of the cables. Moreover, the presence of the insulating pad also helps isolate the direct contact between the installation base and the spacing assembly, reducing wear risks and improving the stability and reliability of the entire bracket system.BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following detailed description refers to the accompanying drawings. These exemplary embodiments are only specific implementations of the present disclosure and are not intended to limit the scope of the present disclosure. The directional terms used in the present disclosure, such as [up] , [down] , [front] , [back] , [left] , [right] , [in] , [out] , [side] , etc., refer to the directions as shown in the accompanying drawings. Therefore, the directional terms used are for illustrating and understanding the present disclosure, not for limiting the present disclosure. In the drawings, similar elements are represented by the same reference numbers. In the drawings, for clear understanding and easy description, some components are exaggerated in size and / or simplified in structure. That is, the size and structure of each component shown in the drawings are schematically shown, and the present disclosure is not limited thereto.
[0039] Referring to FIG. 1, FIG. 1 is a perspective view of a cable support bracket 100 according to an exemplary embodiment of the present disclosure. According to the embodiment of the present disclosure, a cable support bracket 100 is provided, which can include: a frame assembly 1, a spacing assembly 2, and an installation base 3. The spacing assembly 2 can be installed on one side of the installation base 3, in the FIG. shown as the upper side of the installation base. The frame assembly 1 can be movably coupled to the installation base 3 via a coupling device 4, enabling the frame assembly 1 to have at least a fully open state and a closed state. According to the embodiment of the present disclosure, in the fully open state, the spacing assembly 2 does not contact the frame assembly 1, and in the closed state, the spacing assembly 2 abuts the frame assembly 1 to form at least one aperture 50 for the cable to pass through.
[0040] Referring to FIGS. 2 to 4. FIG. 2 is a front view of the cable support bracket 100 with the frame assembly in a unilaterally opened state, according to an exemplary embodiment of the present disclosure. FIG. 3 is a front view of the cable support bracket 100 with the frame assembly in a bilaterally opened state, according to an exemplary embodiment of the present disclosure. FIG. 4 is a front view of the cable support bracket 100 with the frame assembly in a closed state, according to an exemplary embodiment of the present disclosure. According to the embodiment of the present disclosure, the frame assembly 1 can include two arms 11, which are shaped such that when they rotate towards each other via the coupling device 4 to achieve the closed state, the two arms 11 and the installation base 3 together form a rounded, closed shape when viewed from a direction perpendicular to the plane of rotation. Although three apertures 50 are shown in FIGS. 1 to 4, and cable sections passing through the three apertures 50 are shown, it is understood that this does not constitute any limitation on the present disclosure. Those skilled in the art can easily appreciate that the shape and / or size of the arms 11, the spacing assembly 2, and / or the installation base 3 can be adjusted as needed to form one or more apertures different in number and shape from the apertures 50 shown in the figures, so that cables of different sizes, cross-sections, and numbers can pass through the bracket 100 and be fixed by the bracket 100.
[0041] FIG. 5 is a partial perspective view of the cable support bracket 100 according to an exemplary embodiment of the present disclosure. As shown in the figure, the coupling device 4 can include two rotatable members 41, with each arm 11 corresponding to one rotatable member 41. The rotatable member 41 is located at the first end 111 of the arm 11 and is movably coupled to the installation base 3. By integrating the rotatable member 41 at the first end 111 of each arm 11, a movable coupling between the arm 11 and the installation base 3 is achieved, providing a highly flexible bracket structure, for example, the arm 11 can rotate to achieve and maintain both the fully open state and the closed state, and can maintain any position between the fully open state and the closed state. Referring back to FIGS. 2 and 3, the cable support bracket 100 proposed in the present disclosure can also be opened unilaterally or bilaterally at the same time. In the case of bilateral simultaneous opening, the opening angles of the two arms 11 can also be different. It should be noted that the opening angles of the frame assembly 1 (e.g., arms 11) shown in FIGS. 2 and 3 do not necessarily correspond to the fully open state, so the posture, angle, position, etc., of the components shown in the figures do not constitute any limitation on the present disclosure.
[0042] FIG. 6 is a schematic perspective view of the spacing assembly of the cable support bracket 100 according to an exemplary embodiment of the present disclosure. As shown in the figure, the spacing assembly 2 can include a plurality of support frames 21. Each of the plurality of support frames 21 can be connected to at least one other of the plurality of support frames 21 via a connecting device. In the example, the spacing assembly 2 can be arranged in a "Y" shape to separate the cables and reduce the mutual influence of the magnetic fields between the cables, as depicted in the figure. In the example, the support frame 21 can have reinforcing ribs or flanges to increase structural strength. It is understood that although the Y-shaped spacing assembly 2 is shown in the figure, this does not constitute any limitation on the present disclosure, and those skilled in the art can easily appreciate that the number, size, and shape of the support frames 21 can be changed to obtain a spacing assembly different from the Y-shaped spacing assembly 2 shown in the figure.
[0043] FIG. 7 is a perspective view of the cable support bracket 100 according to an exemplary embodiment of the present disclosure. FIG. 8 is a front view of the cable support bracket 100 according to an exemplary embodiment of the present disclosure. Unlike the bracket 100 shown in FIGS. 1 to 6, the bracket 100 shown in FIGS. 7 and 8, when the frame assembly 1 (e.g., two arms 11) rotates towards each other to achieve the closed state, presents a rounded quadrilateral shape when viewed from a direction perpendicular to the plane of rotation, rather than a rounded triangular shape. This is because, in FIGS. 7 and 8, the spacing assembly 2 includes four support frames 21, which form a cross structure. In some cases, there may be four power transmission cables, so the construction of the bracket 100 shown in FIGS. 7 and 8 may be particularly advantageous.
[0044] FIG. 9 is a partial perspective view of the cable support bracket according to an exemplary embodiment of the present disclosure. FIG. 10 is a top view of the cable support bracket according to an exemplary embodiment of the present disclosure. According to the embodiment of the present disclosure, the bracket 100 can also include a locking device 5, which is used to tighten the two arms 11 when they are closed, preventing relative displacement between the arms or allowing relative displacement within an allowable range, for example, to prevent swing caused by thermal expansion of the cables or electromagnetic forces during power transmission. In the example, the locking device 5 is located at the second end 112 of the arm 11, opposite to the first end 111. Specifically, the second end 112 can include a tab 1121, and the tab 1121 can have a hole for a bolt to pass through and a nut to tighten.
[0045] Referring back to FIG. 1, according to the embodiment of the present disclosure, the bracket 100 can also include a fixing base 6 and a sliding mechanism 7. The fixing base 6 can have fixing parts 61 and a receiving part 62, with the fixing parts 61 located at both ends of the receiving part 62. According to the embodiment of the present disclosure, the fixing parts 61 has installation holes. According to the embodiment of the present disclosure, the receiving part 62 is constructed such that the installation base 3 is accommodated in the fixing base 6. According to the embodiment of the present disclosure, the sliding mechanism 7 is constructed such that the installation base 3 can slide relative to the fixing base 6. In the example, the sliding mechanism 7 can include one or more limiting members 71 and one or more waist-limiting holes 72. Specifically, the installation base 3 is provided with the limiting members 71, and the receiving part 62 of the fixing base 6 is provided with the waist-limiting holes 72. The limiting members 71 correspondingly passes through the waist-limiting holes 72. It should be noted that although the limiting members 71 and the waist-limiting holes 72 are only shown as provided on the front side of the drawing (i.e., the front sides of the installation base 3 and the fixing base 6 are provided with the limiting members 71 and the waist-limiting holes 72, respectively) , it is easy to understand that the limiting members 71 and the waist-limiting holes 72 can additionally or alternatively be provided on the back side of the drawing (i.e., the back side of the installation base 3 and the fixing base 6 are provided with the limiting members 71 and the waist-limiting holes 72, respectively, or the waist-limiting holes 72 are aligned and provided on the front and back sides of the fixing base 6 and the limiting members 71 provided on the front and back sides of the installation base 3 pass through the corresponding waist-limiting holes 72 to slide consistently in the front and back waist-limiting holes 72, and so on so forth) .
[0046] Continuing to refer to FIG. 10, as mentioned above, the installation holes can include a first waist-limiting installation hole 81 and a second waist-limiting installation hole 82 that are perpendicular to each other. As an example rather than a limitation, one of the fixing parts 61 (e.g., the left fixing part) has the first waist-limiting installation hole 81, and the other fixing part 61 (e.g., the right fixing part) has the second waist-limiting installation hole 82. Having the fixing parts of the fixing base equipped with the vertically arranged first and second waist-limiting installation hole allows the bracket to adapt to the S-shaped arrangement of cables, allowing a single bracket to rotate as needed in the S-shaped cable layout, for example, within the respective tolerances of the horizontal direction (e.g., the first direction x shown in FIG. 1) and the vertical direction (e.g., the second direction y shown in FIG. 1, essentially perpendicular to the first direction) of the fixing base plane, increasing the installation flexibility of the bracket. It can be seen that the difference between FIG. 10 and FIG. 1 is that there are no bolts fixed in the first waist-limiting installation hole 81 and the second waist-limiting installation hole 82 to more clearly show the vertical arrangement of the first waist-limiting installation hole 81 and the second waist-limiting installation hole 82. According to the embodiment of the present disclosure, the first waist-limiting installation hole 81 and the second waist-limiting installation hole 82 are configured for an adjustable fixation of the cable support bracket. As used herein, the term “adjustable fixing” refers to allowing the bracket to undergo a certain degree of adjustment or movement (for example, rotation, sliding, etc. ) during installation or operation to accommodate different installation conditions or changes in the layout of the cables. This design enables the bracket to be flexibly fixed to power facilities, for instance, by rotating, sliding, or other movements to adapt to the layout and tension management of the cables.
[0047] FIG. 11 is a partial perspective view of the cable support bracket according to an exemplary embodiment of the present disclosure. In the example, a set of opposite edges of the installation base 3 in the first direction (e.g., the length direction x of the installation base 3 shown in FIGS. 2 to 4) extends substantially vertically away from the installation base 3 to form a first side wall 31, and the far end of the first side wall 31 bends inwardly perpendicular to the first side wall to form a pair of feet 32. Accordingly, the receiving part 62 has a set of second side walls 63 oppositely arranged, allowing the installation base 3 to fit within the fixing base 6, for example, the second side wall 63 is outside the first side wall 31 (e.g., can fit against, contact the first side wall) , thereby forming a tunnel-like space. In the example, the sliding mechanism 7 can additionally include a rolling member 73 (e.g., a cow eye swivel wheel) , which is mounted on the first foot 32 and can roll along the first direction x on the fixing base 6. Thereby, it can help the smooth movement of the sliding mechanism 7. In the example, the rolling member 73 can be a standard piece and can be selected according to the load.
[0048] FIG. 12 is a schematic partial disassembly diagram of the cable support bracket according to an exemplary embodiment of the present disclosure. According to the embodiment of the present disclosure, the connecting device can include pairs of protrusions 91 and recesses 92 provided on the installation end surface of the support frame. As an example rather than a limitation, the plurality of support frames 21 include a lower support frame 211 and two upper support frames 212. Internal threaded holes can be formed through the upper support frames 212, and nuts can be provided at the recesses 92 of the lower support frame 211. Accordingly, the connecting device can also include a bolt 93, which passes through the internal threaded hole and tightens to the nut to secure the upper support frame 212 to the lower support frame 211.
[0049] FIG. 13 is a schematic diagram of the application scenario of the cable support bracket according to an exemplary embodiment of the present disclosure. As shown in the figure, the cable support brackets arranged along the S-shaped extension trajectory of the cables can effectively disperse the stress on the cables, avoiding stress concentration caused by straight pulling or tightening, reducing the risk of cable damage. At the same time, this arrangement provides a certain flexibility for the cables, allowing them to adapt to length changes due to temperature changes or other external forces, reducing mechanical stress caused by thermal expansion and contraction, thereby enhancing the durability and reliability of the cables.
[0050] FIG. 14 is a perspective view of the cable support bracket with the sliding mechanism in an un-slid state, according to an exemplary embodiment of the present disclosure. FIG. 15 is a perspective view of the cable support bracket with the sliding mechanism in a slid state, according to an exemplary embodiment of the present disclosure. It is understood that the size of the waist-limiting hole 72 can be adjusted as needed to provide an appropriate amount of sliding. It can also be seen that at least the inner side of each arm 11 can be equipped with a sheath 113. As an example rather than a limitation, a groove can be provided on the arm 11 for the sheath 113. Additionally or alternatively, an insulating pad 114 can be provided on the side of the installation base 3 where the spacing assembly 2 is installed, with the insulating pad 114 being sandwiched between the spacing assembly 2 and the installation base 3.
[0051] FIG. 16 is a partial perspective view of the cable support bracket according to an exemplary embodiment of the present disclosure. For clarity, the right arm 11 is not shown. It is easy to appreciate that the bolt 93 can be tightened when the arm 11 is in an open state to secure the upper support frame 212 to the lower support frame 211, thereby completing the assembly of the spacing assembly 2.
