Abstract
Description
Technical Field
[0001] This utility model belongs to the field of circuit cable safety design technology, and specifically relates to a high-temperature resistant and heat-dissipating cable for protective circuits with high safety. Background Technology
[0002] In electrical circuits, cables are a common component for current flow. However, in many circuit construction projects, cable installation is not strictly regulated, leaving many cables exposed to the environment and susceptible to damage from mechanical impacts and chemical corrosion. This significantly impacts cable lifespan and reduces circuit safety. Furthermore, the spacing between cables is often not carefully controlled during installation, leading to cable congestion and tangling over time. This prevents heat dissipation, increasing the risk of short circuits and fires, thus posing significant safety hazards to the circuit. Utility Model Content
[0003] To solve the above technical problems, this utility model provides a high-temperature resistant and heat-dissipating cable for protective circuits with high safety, including a cable tray body. The cable tray body is a horizontal strip channel with an axial direction of left and right. Both ends of the strip channel are open in the axial direction. Mounting brackets are detachably and fixedly installed at both ends of the strip channel in the axial direction.
[0004] Each mounting bracket includes a mounting rod that runs horizontally in the front-to-back direction. Several sliding rods extend vertically upwards at even intervals along the length of the mounting rod. Several sets of support components are coaxially sleeved on the sliding rods along their length. Each support component includes an upper support ring that can be coaxially and slidably sleeved on the sliding rod, a lower support ring that can be coaxially and slidably sleeved on the sliding rod, and a spring located between the upper and lower support rings (vertically fixed to the upper support ring upwards and vertically fixed to the lower support ring downwards) and coaxially and slidably sleeved on the sliding rod.
[0005] The cable body, whose length direction is consistent with the strip channel, passes through the strip channel and passes between two adjacent sliding rods. It simultaneously abuts against the two sets of support components adjacent to one of the two sliding rods, and the two sets of support components adjacent to the other sliding rod. The upper part of the mounting frame is a pressure rod parallel to the mounting rod in the length direction. The pressure rod presses against the support components vertically downward on each sliding rod and puts each spring in a state of compression along its own axis, thereby forming an elastic clamp on the cable body through the corresponding support components.
[0006] Preferably, the pressure rod can be vertically slidably fitted onto each slide rod. The slide rod has several first threaded through holes with a horizontal axis in the left and right direction at intervals along the vertical direction. The clamping bolts tightened in the first threaded through holes by thread engagement press down against the pressure rod, and the pressure rod presses down against the support component, so that each spring is in a state of being compressed along its own axis, thereby forming an elastic clamp on the cable body through the corresponding support component.
[0007] As a preferred embodiment, the mounting rod is provided with several vertical second threaded through holes at intervals along its length. At the bottom of the strip channel near the two ends of the strip channel, a vertical third threaded through hole is provided, corresponding to the second threaded through hole on the corresponding mounting bracket. By simultaneously tightening the positioning bolts in the corresponding second and third threaded through holes, the mounting rod and mounting bracket can be detachably and fixedly installed at the two ends of the strip channel.
[0008] Preferably, the bottom of the strip channel is located at the center, facing upwards, and has a groove with the same length direction as the strip channel. One end of the groove is connected to one end face of the strip channel along its own length direction, and the other end extends to another end face close to the axial direction of the strip channel and is closed. A slider extends vertically downwards from the center of the mounting rod along its own length direction. The slider is structurally matched with the radial cross-section of the groove. The mounting frame is driven to slide synchronously in the strip channel by sliding in the groove along the length direction of the groove.
[0009] Preferably, both the upper and lower support rings are vertically oriented circular rings. The outer edge of the horizontal upper end face of the upper support ring, which may come into contact with the cable body, and the outer edge of the horizontal lower end face of the lower support ring, which may come into contact with the cable body, are both rounded edges.
[0010] Preferably, the cable body passes between two adjacent sliding rods and simultaneously abuts against the lower arc edge of the lower support ring of the upper support member on the front sliding rod, the upper arc edge of the upper support ring of the lower support member on the front sliding rod, the lower arc edge of the lower support ring of the upper support member on the rear sliding rod, and the upper arc edge of the upper support ring of the lower support member on the rear sliding rod.
[0011] As a preferred embodiment, several heat dissipation vents connecting the inner cavity of the strip channel to the outside are evenly arranged at intervals along the length of the strip channel on both the front and rear sides. Attached Figure Description

[0017] It should be noted that the terms “up,” “down,” “left,” “right,” “front,” “back,” “horizontal,” “vertical,” “top,” and “bottom” used in the description of this application refer to the directions in the accompanying drawings, while “inner” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively. These are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.
[0018] As attached Figure 1 , 2 As shown in Figures 3 and 4, the high-temperature resistant and heat-dissipating cable for the high-safety protective circuit of this utility model includes a cable tray body. The cable tray body is a horizontal strip channel 1 with the axial direction in the left and right directions. The radial cross-section of the strip channel 1 is a rectangular frame with the axial direction set upright. Both ends of the strip channel 1 are open. Mounting brackets are detachably fixed at both ends of the strip channel 1.
[0019] As attached Figure 2 , 3Each mounting bracket includes a horizontal mounting rod 2 extending forward and backward along its length. Several sliding rods 3 extend vertically upward at even intervals along the length of the mounting rod 2. Several sets of support components are coaxially fitted onto each sliding rod 3 along its length. Each support component includes an upper support ring 4 that can be coaxially and slidably fitted onto the sliding rod 3, a lower support ring 5 that can be coaxially and slidably fitted onto the sliding rod 3, and a vertically upward fixed connection to the upper support ring 4 and a vertically downward fixed connection between the upper support ring 4 and the lower support ring 5. The spring 6, which is coaxially slidably fitted onto the slide rod 3 and is located on the lower support ring 5, has the same specifications for all support components. Both the upper support ring 4 and the lower support ring 5 on the support components are vertically oriented circular rings. The outer edge of the horizontal upper surface of the upper support ring 4 (excluding the topmost upper support ring 4 on the slide rod 3), which may come into contact with the cable body 7, and the outer edge of the horizontal lower surface of the lower support ring 5 (excluding the bottommost lower support ring 5 on the slide rod 3), are both rounded edges (as shown in the attached diagram). Figure 4 );
[0020] The cable body 7, with its length aligned with the strip channel 1, is suspended and passes through the strip channel 1 while passing between two adjacent sliding rods 3. The cable body 7 simultaneously abuts against the lower arc edge of the lower support ring 5 of the upper support member on the front sliding rod 3, the upper arc edge of the upper support ring 4 of the lower support member on the front sliding rod 3, and the lower arc edge of the lower support ring 5 of the upper support member on the rear sliding rod 3, and the upper arc edge of the upper support ring 4 of the lower support member on the rear sliding rod 3. Meanwhile, the upper part of the mounting frame is a cable with its length aligned with... The mounting rod 2 is parallel to the pressure rod 8. The pressure rod 8 can slide vertically and is simultaneously fitted onto each slide rod 3. On the slide rod 3 that is centered at the front and back (the total number of slide rods 3 on the same mounting frame is odd), several first threaded through holes 31 are evenly spaced along the vertical direction. The clamping bolts 9, which are screwed into the first threaded through holes 31, press down against the pressure rod 8. The pressure rod 8 presses down vertically against the support component (the uppermost one on each slide rod 3) on each slide rod 3, and puts the springs 6 below in a state of compression along their own axis. Thus, the corresponding support component forms an elastic clamp on the cable body 7.
[0021] The bottom of the strip channel 1 is located at the center, facing upwards, and has a groove 11 with the same length direction as the strip channel 1. One end of the groove 11 is connected to the left end face of the strip channel 1 along its own length direction, and the other end extends to the right end face near the axial direction of the strip channel 1 and is closed. A slider 21 extends vertically downwards from the center of the mounting rod 2 along its own length direction. The slider 21 is structurally matched with the radial cross-section of the groove 11 (the slider 21 extends vertically downwards further to the outside of the strip channel 1 through the groove 11). The slider 21 moves along the length of the groove 11. The directional sliding drives the corresponding mounting rod 2 and mounting bracket to slide synchronously within the strip channel 1 (the slide groove 11 is provided with a slot consistent with its own length direction, and the slider 21 is provided with a locking block 111 that cooperates with the slot. The locking block 111 can slide back and forth and fit into the slot to prevent the mounting bracket from tilting to the left or right within the strip channel 1. This also facilitates the subsequent mounting bracket sliding to the specified position within the strip channel 1, so that the positioning bolt 10 can be smoothly screwed into the second threaded through hole 22 on the mounting rod 2 to fix the mounting bracket).
[0022] Meanwhile, the mounting rod 2 has several vertically oriented second threaded through holes 22 spaced along its length. At the bottom of the strip channel 1 near the two ends of the strip channel 1, vertically oriented third threaded through holes 12 are respectively opened one-to-one with the second threaded through holes 22 on the corresponding mounting bracket. By simultaneously tightening the positioning bolts 10 in the corresponding second threaded through holes 22 and third threaded through holes 12 with thread engagement, the corresponding mounting rod 2 and mounting bracket can be detachably and fixedly installed at the two ends of the strip channel 1.
[0023] Several heat dissipation vents 13 are evenly arranged at intervals on the front and rear sides of the strip channel 1 along the length of the strip channel 1 to connect the inner cavity of the strip channel 1 with the outside world, so as to promote the heat dissipation of the air entering and exiting the strip channel 1 and avoid the continuous high temperature overheating of the cable body 7.
[0024] In this design, the cable tray body acts as a protective component for the circuit, enclosing multiple cable bodies 7 within the circuit. This effectively reduces damage to the cable bodies 7 from external mechanical impacts, chemical corrosion, and other factors, thus improving safety. Inside the cable tray body, as long as the radial dimension (diameter) is smaller than the horizontal distance between two adjacent sliding rods 3 on the mounting bracket (i.e., the... Figure 4 The "D" in the figure, and greater than the horizontal distance between the corresponding upper support ring 4 (lower support ring 5) on the two adjacent slide rods 3 (i.e., attached) Figure 4 The “d” in the text refers to the (round bar-shaped) cable body 7, which is applicable to all of them.
[0025] First, prepare the required number of cable bodies 7 (each cable body 7 has the same thickness) as shown in the attached document. Figure 1 , 3The cable bodies are distributed from left to right and pass through two identical mounting frames. After installation, the sliding rod 3 prevents different cable bodies 7 from crossing or misaligning. The upper support ring 4 and lower support ring 5 prevent different cable bodies 7 from crossing or misaligning. Therefore, even if the pressure rod 8 is not pressed down, the distribution of the cable bodies 7 on each mounting frame will not be disordered, thus avoiding safety hazards caused by multiple cable bodies 7 gathering and crossing.
[0026] Press the pressure rod 8 on the right mounting bracket vertically down onto each sliding rod 3 until the pressure rod 8 just reaches below a first threaded through hole 31 on the mounting bracket. At the same time, ensure that when the pressure rod 8 is pressed down to this position, each cable body 7 passing through the mounting bracket is clamped inward in a circumferential direction so that it cannot easily slide left or right on the mounting bracket. At this time, use the clamping bolt 9 to tighten it into the first threaded through hole 31 to achieve fixation.
[0027] Then, after the slider 21 on the right mounting bracket is inserted into the slide groove 11 from left to right, the slider 21 is held outside the strip channel 1 and slid to the right in the slide groove 11, thereby controlling the right mounting bracket to move to the right end of the strip channel 1, and driving the cable bodies 7 on it to pass through the strip channel 1. Then, the mounting bracket is vertically fixed at the right end of the strip channel 1 by the positioning bolt 10.
[0028] In the same manner, the mounting bracket on the left is installed and vertically fixed to the left end of the strip channel 1 by the positioning bolt 10; after pulling each cable body 7 passing through the mounting bracket to the left horizontally at the left end of the strip channel 1, the pressure rod 8 on the left mounting bracket is pressed down in the same way as above and fixed with the clamping bolt 9, thereby ensuring that the cable segments passing through the strip channel 1 on each cable body 7 extend horizontally from left to right, thus preventing these cable segments from drooping close to the bottom of the inner cavity of the strip channel 1, and the assembly is completed.
[0029] The above-mentioned measures ensure that the cable segments on each cable body 7 that pass through the strip channel 1 extend horizontally in the left and right directions. On the one hand, this is to ensure that there is a gap between the cables in the cable tray body of the strip channel 1, so as to avoid them being squeezed together. This is conducive to the heat dissipation of the cables in the cable tray body and avoids the accumulation and crossing of multiple cable bodies 7, which could cause overheating and safety hazards. On the other hand, external moisture will enter the strip channel 1 from the two ends of the axial direction or the heat dissipation port 13, and eventually form a certain amount of water at the bottom of the strip channel 1 cavity. When the cable body 7 is close to or directly falls on the bottom of the strip channel 1 cavity, it will be penetrated and corroded by this water.
[0030] It is also easy to see that, based on the above installation, subsequent adjustments only require removing and installing the clamping bolts 9 on the two mounting brackets. This allows for the addition, removal, or movement of cable bodies 7 directly on the cable tray body while both mounting brackets remain fixed in place. There is no need to worry about cross-contamination or misalignment between other cable bodies 7 on the mounting brackets, thus eliminating the need for large-scale rewiring. This flexibility makes this cable solution ideal for applications requiring frequent wiring adjustments.
[0031] From the appendix Figure 2 It can be seen that in this scheme, the cable body 7 is stably installed on the cable tray body by the elastic clamping of four supporting components on two adjacent sliding rods 3 (two adjacent supporting components on each sliding rod 3). This can be achieved simply by pressing down with the pressure rod 8, which has an automatic adjustment function and a simple structural design. Furthermore, as long as the radial dimension (diameter) of the (quasi-circular) cable body 7 is less than the horizontal distance between two adjacent sliding rods 3 (i.e., the attached...), the cable body 7 can be installed stably on the cable tray body. Figure 4 The "D" in the figure is greater than the horizontal distance between the corresponding upper support ring 4 (lower support ring 5) on the two adjacent sliding rods 3 (i.e., the attached figure). Figure 4 The “d” in the figure can be stably and quickly assembled and installed on the cable tray body of this application using the above-described clamping method. Therefore, there is no strict limitation on the thickness of the cable body 7, and it is more applicable to cable bodies 7 of different specifications and sizes.
[0032] Based on this, within the strip channel 1, which serves as the cable tray body, the cable body 7 only comes into contact with the cable body 7 through the edges of the upper support ring 4 (lower support ring 5) at both axial ends of the strip channel 1. This is to minimize the area covered by the cable body 7 within the strip channel 1, thus facilitating heat dissipation of the cable body 7. Furthermore, designing the edges of the upper support ring 4 (lower support ring 5) as rounded corners reduces the risk of scratching or tearing the outer sheath of the cable body 7 when they come into contact with it (as shown in the attached diagram). Figure 4 ).
