Description

Technical Field

[0001] This application relates to the field of cable installation technology, specifically to a cable fixing device and a power system. Background Technology

[0002] Cables are an essential infrastructure of modern electrified and information-based societies, primarily used for transmitting electricity (such as power lines and high-voltage cables) or data and signals (such as network cables and fiber optic cables). During cable laying, to ensure safety, supports are used to secure and fix the cables, preventing internal wire breakage and insulation wear due to stepping, dragging, or bending. This also prevents loose connections and poor contact caused by cable movement, ensuring the reliability of cable connections.

[0003] However, existing brackets typically place the fixing part for connecting to the mounting surface and the opening for the cable to be inserted into the cable tray on opposite sides. This means that the bracket can only support the cable from below. In scenarios where the cable needs to be placed under the bracket, the opening will be below the cable. Due to the lack of support, the cable will detach from the cable tray through the opening, resulting in the cable being suspended. This not only poses a safety hazard but may also cause the equipment to malfunction. Utility Model Content

[0027] Cables play a vital role in modern society, transmitting electrical energy from power plants to homes, factories, and businesses, powering the world. They also enable the instantaneous transmission of data, sound, images, and other information between different devices and locations, building the information society. Currently, cables are primarily secured using brackets. These brackets typically have a fixing part for fixed connection to the mounting surface and a cable tray for cable installation. The opening of the cable tray is located on the side of the bracket opposite the fixing part, allowing the cable to be inserted into the tray through the opening and supported and secured by the inner wall of the tray.

[0028] However, in scenarios where cables need to be placed under the bracket, such as cables laid on the ceiling or cables laid above equipment and installed along the production line, the bracket needs to be placed upside down on the ceiling or above the equipment. In this case, after the cable is inserted into the cable tray, the opening is located directly below the cable. Since there is no supporting structure below the cable, the cable is prone to falling out of the opening under the influence of gravity.

[0029] Suspended cables detached from their supports are not only prone to snagging or pulling, causing connected equipment to fall from heights and resulting in equipment damage and personal injury, posing significant safety hazards, but their own weight also generates continuous tension. Over time, this can deform the internal conductors, altering their characteristic impedance and causing signal reflection, attenuation, data loss, and reduced network speed, ultimately leading to equipment malfunction. Furthermore, in environments with slight vibrations or airflow, cables can sway gently like ropes, causing connectors at the cable ends to loosen or become loose, resulting in intermittent equipment failure.

[0030] Therefore, to better secure cables, this application provides a cable securing device. This device includes a guide bar, with a fixing part and a cable groove respectively provided on both sides of the guide bar along the vertical direction. The opening of the cable groove is located on one side of the guide bar along the horizontal direction, and the width of the opening is smaller than the outer diameter of the cable. When the cable is inserted into the cable groove through the opening, the two walls of the cable groove along the vertical direction are located on the upper and lower sides of the cable, respectively. Whether the guide bar is installed upright or upside down, the cable can be supported and secured by the vertical walls of the cable groove, preventing the cable from falling off the guide bar, avoiding safety issues, improving the stability of the cable, ensuring a stable connection between the cable and the equipment, and guaranteeing the normal operation of the equipment.

[0031] According to a first aspect of the embodiments of this application, a cable fixing device is provided. Please refer to... Figure 1 and Figure 2 , Figure 1 A perspective view of the cable fixing device is shown. Figure 2 It shows Figure 1 The enlarged structure at point A shows that the cable fixing device 100 includes a guide bar 110, which is the main body of the cable fixing device 100. The cable 200 is laid by setting the installation position of the guide bar 110. For example... Figure 1 and Figure 2 As shown, the guide bar 110 has a fixing part 111 on one side along the vertical direction (i.e., the direction shown by the Z axis in the figure), and a wire groove 112 is opened on the other side.

[0032] The fixing part 111 is used to connect with the mounting surface, which can be a ceiling surface, floor, tabletop, etc. The fixing part 111 can be attached to the mounting surface by adhesive, or fixed by screws, nails, clips, or other structures. The guide strip 110 can... Figure 1 The device is upright on the mounting plane, with the wire groove 112 positioned above the fixing part 111. Specifically, the fixing part 111 is located on the side of the guide bar 110 facing the negative Z-axis, while the wire groove 112 is located on the side of the guide bar 110 facing the positive Z-axis. Alternatively, it can be... Figure 1 The guide bar 110 is arranged upside down on the mounting plane as shown, so that the wire groove 112 is located below the fixing part 111.

[0033] The fixing part 111 can be directly connected to the mounting surface, or it can be indirectly connected to the mounting surface via a bracket. As an example, such as... Figure 1As shown, the cable fixing device 100 also includes a bracket 120. The bracket 120 can be fixedly connected to the mounting surface by means of adhesive, screws, clips, etc. The bracket 120 is also provided with a U-shaped groove 121, and the U-shaped groove 121 has an opening 122 facing the vertical direction. The fixing part 111 can be inserted into the U-shaped groove 121 through the opening 122 and fixedly connected to the bracket 120 by means of snap-fit ​​structure, interference fit, etc., thereby realizing the connection between the guide strip 110 and the mounting surface.

[0034] The extension direction of the cable tray 112 is parallel to the extension direction of the guide strip 110. The installation position and extension direction of the guide strip 110 and the cable tray 112 determine the cable laying path and overall layout, such as... Figure 1 As shown, both the guide bar 110 and the cable tray 112 extend along the Y-axis. Therefore, after the cable is inserted into the cable tray 112, it can only run along the Y-axis. When laying the cable, the guide bar 110 can be installed on the mounting surface according to the design drawings, and then the cable can be inserted into the cable tray 112 of the guide bar 110.

[0035] The length of the guide bar 110 can be set according to actual needs. For example, when the cable is heavy, the length of the guide bar 110 can be set to be equal to the length of the cable, so that the guide bar 110 can support and fix the cable at various positions to ensure the stability of the cable. When the cable is light, the length of the guide bar 110 can be set to be smaller, and multiple guide bars 110 can be set at intervals according to the cable routing direction to support and fix the cable, so as to save materials and reduce costs.

[0036] like Figure 2 As shown, the slot 1121 of the wire groove 112 is located on one side of the guide strip 110 along the horizontal direction. The slot 1121 can be directly facing the horizontal direction or it can be inclined. For example, the slot 1121 can be inclined upwards or inclined downwards. Furthermore, as... Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 Partial cross-sectional views of the cable fixing device in two states are shown respectively. The width of the slot 1121 is smaller than the outer diameter of the cable 200. When the cable 200 is inserted into the cable groove 112 from the slot 1121, it can effectively prevent the cable 200 from leaving the slot 1121 and the cable groove 112.

[0037] Cable 200 typically has a sheath, usually made of durable PVC or rubber. When installing cable 200, the sheath can be compressed to insert it into cable tray 112 from opening 1121. Alternatively, guide strip 110 can be made of PVC alloy or PC alloy, allowing the vertical side walls of cable tray 112 to bend and deform to a certain extent. This allows the vertical side walls of cable tray 112 to expand outwards under the pressure of cable 200, increasing the width of opening 1121 and ensuring proper installation of cable 200.

[0038] The size of the internal space of the cable tray 112 can be designed according to the installation method of the cable 200. For example, since power cables need to transmit large currents and generate strong magnetic fields, in order to prevent electromagnetic interference, power cables usually need to be installed in a separate cable tray, such as... Figure 4 As shown, the inner wall of the wire trough 112 can be designed as an arc, and the inner diameter of the wire trough 112 can be designed to be smaller than the outer diameter of the cable 200. When the cable 200 is installed in the wire trough 112, the inner wall of the wire trough 112 can clamp and fix the cable 200 to improve the stability of the cable 200.

[0039] Of course, for cables 200 such as optical cables, communication cables, and control cables, multiple cables 200 can be placed in the same cable tray 112. In this case, the internal space of the cable tray 112 can be designed to be larger so that the cable tray 112 can accommodate multiple cables 200, thereby reducing the number of guide strips 110 required for laying cables 200 and making the wiring on the installation plane simpler.

[0040] Furthermore, to make the installation of cable 200 more convenient, such as Figure 2 and Figure 3 As shown, the guide strip 110 has guide arc surfaces 113 formed on both sides of the slot 1121. When the cable 200 is inserted into the slot 112, the guide arc surfaces 113 will move as follows: Figure 3 As shown, it abuts against the outer surface of the cable 200, thereby guiding the movement direction of the cable 200 through the guide arc surface 113, making the installation of the cable 200 smoother.

[0041] Considering that when installing cable 200, the guide strip 110 is first installed on the mounting surface, and then cable 200 is inserted into the cable tray 112, in order to reduce the impact of cable 200 installation on the connection structure between the fixing part 111 and the mounting surface, in some embodiments, such as Figure 3 As shown, the slot 1121 is inclined in a direction away from the fixing part 111. Figure 3Taking the structure shown as an example, the fixing part 111 is located below the cable trough 112, and the slot 1121 is designed to be inclined upward. When installing the cable 200, an inclined downward force needs to be applied to the cable 200 so that the cable 200 can enter the cable trough 112 from the slot 1121. At this time, the guide bar 110 will also be subjected to the inclined downward force applied by the cable 200. This force will generate a downward component force, which makes the fixing part 111 tend to move towards the mounting plane, thereby improving the stability of the connection between the fixing part 111 and the mounting plane.

[0042] like Figure 1 and Figure 4 As shown, when the guide strip 110 is installed upright on a mounting surface such as the ground or a desktop, the fixing part 111 is located below the cable trough 112. The inner wall B of the cable trough 112 near the fixing part 111 is located below the cable 200. The cable 200 will abut against the inner wall B under the action of gravity, thereby providing stable support to the cable 200 through the inner wall B. Figure 5 As shown, Figure 5 The diagram shows a cross-sectional view of the cable fixing device in a third configuration. When the guide bar 110 is inverted and installed on a mounting surface such as a ceiling, although the fixing part 111 is located above the cable trough 112, the inner wall C of the cable trough 112, away from the fixing part 111, is located directly below the cable 200. The cable 200 will abut against the inner wall C under the influence of gravity, thus providing stable support to the cable 200 through the inner wall C. Therefore, whether the guide bar 110 is installed upright or inverted, the cable trough 112 can provide stable support to the cable 200 through its inner wall, ensuring the stability of the cable 200 and expanding the applicable scenarios of the guide bar 110.

[0043] In the above embodiment, the fixing part 111 and the wire groove 112 are respectively disposed on both sides of the guide strip 110 in the vertical direction, and the groove opening 1121 of the wire groove 112 is disposed on one side of the guide strip 110 in the horizontal direction. This allows the cable 200 to abut against at least one side of the inner wall of the wire groove 112 in the vertical direction under the action of gravity, regardless of whether the installation surface is the ground or the ceiling surface. This supports and fixes the cable 200 through the inner wall of the wire groove 112, preventing the cable 200 from sagging or bending due to gravity and avoiding affecting the stability of the cable 200's function.

[0044] Furthermore, to facilitate the installation of the guide strip, in some embodiments, such as Figure 6 and Figure 7 As shown, Figure 6 The three-dimensional structure of the bracket in the cable fixing device is shown. Figure 7A partial exploded view of the cable fixing device 100 is shown. The cable fixing device 100 also includes a bracket 120 for fixed connection with the mounting surface. The bracket 120 has a U-shaped groove 121 with an opening 122 facing the vertical direction. The guide strip 110 can be connected to the bracket 120 and fixed to the mounting surface by being inserted vertically into the U-shaped groove 121 through the opening 122.

[0045] The bracket 120 and the guide strip 110 can be connected via a snap-fit ​​structure or an interference fit. As an example, such as... Figure 6 and Figure 7 As shown, the two opposing side walls 123 of the U-shaped groove 121 are flexible and deformable, and the two ends of the opposing side walls 123 of the U-shaped groove 121 in the horizontal direction are formed with protruding walls 124 towards the inside of the U-shaped groove 121, and the protruding walls 124 are provided with limiting notches 125. The fixing part 111 includes a plug post 1111, and the two opposing sides of the plug post 1111 are provided with locking blocks 1112. The plug post 1111 is inserted into the U-shaped groove 121 through the opening 122, so that the locking blocks 1112 are engaged with the limiting notches 125 to realize the connection between the bracket 120 and the guide strip 110.

[0046] Specifically, with Figure 7 Taking the structure shown as an example, when the plug 1111 is vertically inserted into the U-shaped groove 121 from the opening 122, the locking block 1112 will abut against the surface of the convex wall 124 near the opening 122, and provide a component force in the direction of the dashed arrow D to the left side wall 123 of the U-shaped groove 121 and a component force in the direction of the dashed arrow D to the right side wall 123 of the U-shaped groove 121, causing the two side walls 123 of the U-shaped groove 121 to bend and expand outward, thereby making the convex wall 124 clear a path for the plug 1111 to continue moving downward. When the plug 1111 is inserted into place, the locking block 1112 will engage with the limiting notch 125 on the convex wall 124, thereby realizing the connection between the guide strip 110 and the bracket 120.

[0047] The locking block 1112 and the convex wall 124 can be engaged by inclined friction, causing the two side walls 123 of the U-shaped groove 121 to bend outward. Specifically, the surface of the locking block 1112 away from the groove 112 can be designed as an inclined or curved surface, and the surface of the convex wall 124 near the opening 122 can be designed as an inclined or curved surface. Alternatively, both the surface of the locking block 1112 away from the groove 112 and the surface of the convex wall 124 near the opening 122 can be designed as inclined or curved surfaces, so that the force applied by the locking block 1112 to the convex wall 124 can generate a component force that causes the side wall 123 where the convex wall 124 is located to bend and expand outward.

[0048] Furthermore, to make the installation between the guide bar 110 and the bracket 120 easier, such as... Figure 4 and Figure 7 As shown, the bottom of the U-shaped groove 121 and the limiting notch 125 are spaced apart in the depth direction of the U-shaped groove 121 to increase the distance from the connection point of the two side walls 123 of the U-shaped groove 121 to the limiting notch 125. This makes the lever arm of the horizontal component of the force applied by the locking block 1112 to the side wall 123 larger. In this way, only a small force needs to be applied by the locking block 1112 to the side wall 123 to make the side wall 123 bend and expand outward, making the assembly of the guide strip 110 and the bracket 120 easier.

[0049] In the above structure, during the process of inserting the plug 1111 of the fixing part 111 into the U-shaped groove 121 on the bracket 120 through the opening 122, the bending deformation of the two side walls 123 of the U-shaped groove 121 can cause the locking block 1112 on the plug 1111 to be engaged in the limiting notch 125 of the protruding wall 124 on the side wall 123, thereby achieving a fixed connection between the guide strip 110 and the bracket 120 through the engaging connection between the locking block 1112 and the limiting notch 125.

[0050] Furthermore, considering the manufacturing cost of the bracket 120, the protruding walls 124 are located at both ends of the side wall 123 in the horizontal direction. A limiting notch 125 is created on the protruding walls 124 to form a structure that engages with the locking block 1112. This eliminates the need for an additional protrusion in the middle of the side wall 123, thus achieving the engagement between the guide strip 110 and the bracket 120, saving materials and reducing costs. On the other hand, it allows the side wall 123 to maintain the same thickness in all vertical directions. Furthermore, by designing the thickness of the protruding walls 124, the thickness difference between the protruding walls 124 and the side wall 123 can be reduced. This uniform thickness design ensures that the bracket 120 cools evenly during injection molding, die casting, or other processes, resulting in similar cooling times at different locations. This makes the processing of the bracket 120 easier and avoids problems such as shrinkage cavities and porosity caused by different cooling rates.

[0051] Furthermore, considering the disassembly issue between the bracket 120 and the guide bar 110, in order to facilitate the disassembly of the bracket 120 and the guide bar 110, in some embodiments, such as Figure 4 and Figure 6 As shown, a first inclined surface 126 is formed on the surface of the limiting notch 125 near the opening 122, and a second inclined surface 1113 is formed on the surface of the locking block 1112 facing the groove 112. When the locking block 1112 is subjected to force and moves away from the bracket 120, the second inclined surface 1113 provides the first inclined surface 126 with a force that causes the opposite side walls 123 of the U-shaped groove 121 to bend and expand outward.

[0052] Specifically, with Figure 4 Taking the structure shown as an example, when the guide bar 110 is subjected to a vertically upward force, the locking block 1112 will move upward under the action of the force. At this time, the second inclined surface 1113 will abut against the first inclined surface 126. The locking block 1112 can provide a component force along the direction to the two side walls 123 of the U-shaped groove 121 through the second inclined surface 1113 and the first inclined surface 126. That is, the locking block 1112 will provide a component force along the direction indicated by the dashed arrow D to the left side wall 123 of the U-shaped groove 121 and a component force along the direction indicated by the dashed arrow E to the right side wall 123 of the U-shaped groove 121, so that the two side walls 123 of the U-shaped groove 121 bend and expand outward, thereby making the convex wall 124 avoid the path for the locking block 1112 to move upward, so that the locking block 1112 can move upward and be pulled out of the U-shaped groove 121 from the opening 122, so as to realize the disassembly and separation between the guide bar 110 and the bracket 120.

[0053] In the above structure, when it is necessary to maintain and replace the cable 200 in the cable tray 112, or to replace the guide bar 110, it is only necessary to apply a force to the guide bar 110 in the direction away from the bracket 120. The locking block 1112 can then provide an outward bending and expanding force to the two side walls 123 of the U-shaped groove 121 through the first inclined surface 126 and the second inclined surface 1113. This allows the locking block 1112 to move away from the bracket 120 and be pulled out of the U-shaped groove 121 from the opening 122, realizing the quick disassembly and separation between the guide bar 110 and the bracket 120. The disassembly between the guide bar 110 and the bracket 120 is more convenient, which indirectly makes the maintenance and replacement of the cable 200 and the guide bar 110 more convenient.

[0054] Furthermore, considering the production cost of the guide strip 110, in some embodiments, such as Figure 2 and Figure 3 As shown, the guide strip 110 also includes an intermediate section 114 located between the plug post 1111 and the wire groove 112. The cross-sectional area of ​​the intermediate section 114 gradually decreases from the end connected to the wall of the wire groove 112 to the end connected to the plug post 1111, so that the cross-sectional area of ​​the plug post 1111 in the vertical direction is smaller, thereby reducing the material used to produce the guide strip 110 and reducing production costs.

[0055] In addition, such as Figure 3 and Figure 7 As shown, one end of the convex wall 124 facing the opening 122 is flush with the side wall 123 of the U-shaped groove 121, and the convex wall 124 forms an abutting slope 127 at the opening 122. The abutting slope 127 is used to abut against the outer surface of the intermediate section 114 when the insertion post 1111 is inserted into place. In this structure, on the one hand, the insertion post 1111 is as follows Figure 7When the cable is inserted from the opening 122 into the U-shaped groove 121, the abutting slope 127 guides the insertion post 1111, allowing it to enter the U-shaped groove 121 more smoothly. On the other hand, when the cable fixing device 100 is in a... Figure 3 When the cable 200 is supported and fixed in the state shown, the abutting inclined surface 127 can provide a vertical upward component force to the outer surface of the middle section 114, thereby providing a more uniform support force to the cable groove 112 through the middle section 114, making the support and fixation of the cable 200 by the cable fixing device 100 more stable.

[0056] Furthermore, considering the production and processing costs of the guide strip 110, such as Figure 2 and Figure 3 As shown, a through hole 115 is provided through the middle section 114 along the extension direction of the guide strip 110. Furthermore, on a plane perpendicular to the extension direction of the guide strip 110, the orthographic projection contour of the through hole 115 matches the orthographic projection contour of the middle section 114, making the wall thickness at various positions on the middle section 114 relatively similar. This prevents uneven cooling rates due to uneven thickness when the guide strip 110 is produced using injection molding, die casting, or other processes, avoiding problems such as shrinkage cavities and porosity, and improving the quality of the guide strip 110. Figure 3 Taking the structure shown as an example, the cross-sectional area of ​​the middle section 114 gradually decreases from top to bottom in the vertical direction, and the cross-sectional area of ​​the through hole 115 also gradually decreases from top to bottom in the vertical direction.

[0057] According to another aspect of the embodiments of this application, a power system is also provided, which includes a cable 200 and a cable fixing device 100 as described in any of the above embodiments, wherein the cable 200 is installed in the cable groove 112 of the cable fixing device 100.
