Description

Technical Field

[0001] The invention relates to the technical field of weak-current cabinet power installation, and in particular to a high-heat dissipation weak-current cabinet that is convenient for line installation. Background Art

[0002] With the rapid development of modern information technology and communication networks, weak current systems are being used more and more widely in various buildings. As the core component of the weak current system, the weak current cabinet carries a large number of cable lines. The weak current cabinet, also known as the weak current box, is a device used to centrally manage weak voltage lines. It is mainly used in modern home decoration and can hold network cables, telephone lines, computer monitors, USB cables, TV VGA, color difference, antennas and other equipment. Its structure and design directly affect the reliability and maintenance convenience of the system.

[0003] However, in order to protect electrical components, prevent interference, and improve system reliability, it is often necessary to fix electrical components on the cabinet. It is difficult to adjust the position after fixing, and due to the lack of effective line management solutions, wires are easily entangled in the cabinet, resulting in difficulties during maintenance. When handling wires, maintenance personnel often need to spend time and effort to untangle the tangled lines, wasting precious time and energy. When a specific wire needs to be replaced, technicians often find it difficult to quickly find the target wire. Due to the lack of clear identification and reasonable layout, maintenance efficiency is low, which increases the downtime of the system and affects the stability of the overall operation.

[0004] Chinese patent CN114784636B discloses an electrical connection device, which belongs to the technical field of electrical equipment, including an electrical cabinet body, wherein an external wiring mechanism is fixedly connected inside the electrical cabinet body, and a butt-type wiring head is fixedly connected on the inner end face of the external wiring mechanism. In the invention, through the cooperation of the designed external wiring assembly, sealing mechanism, pressure relief assembly and cooling mechanism, the device has good anti-electrocorrosion and heat dissipation properties, strong overall practicality, and meets the needs of users. At the same time, it also improves the stability of the external wire after the electrical connection is completed, so that the pressure inside the junction box is released, and in the process of pressure relief, it can also drive the high-temperature gas inside it, which has the effect of cooling and pressure relief. The gravitational force generated by the rotating airflow can accelerate the cooling of the arc, and the purpose of increasing the axial gradient of the arc column voltage is achieved. In addition, the arc cooling can reduce the contact temperature, thereby achieving the purpose of increasing the near-pole voltage drop.

[0005] The above patent achieves protection against electro-corrosion and good heat dissipation through the provision of external wiring components, sealing mechanisms, pressure relief components and cooling mechanisms, and also plays a role in cooling down while relieving pressure. However, the lines between the external electrical components are not organized, entanglement is inevitable, and when replacing damaged cables, they cannot be found quickly, resulting in low maintenance efficiency and increased system downtime.

[0016] Preferably, a heat dissipation opening is provided on the cabinet.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) The heat dissipation slide provided in the present invention is installed on the heat dissipation slide by a sliding block, and the electrical components are fixed on the sliding block. The installation position of the electrical components can be adjusted, so that the replacement and adjustment of the position of the electrical components becomes simple and quick, and the wiring is convenient, avoiding the defect that the electrical components cannot be adjusted at will after being fixed and installed, resulting in the problem of line entanglement caused by inconvenient replacement of line installation. At the same time, by installing an air pump on the top of the cabinet, air flows into the heat dissipation slide and is distributed to the cabinet through the horizontal heat dissipation slide and the vertical heat dissipation slide to cool the cabinet. When the sliding block slides, the strip rubber pads installed on the C-shaped notch are squeezed, so that the sliding block can slide. When the sliding block slides, the strip rubber pads on both sides fit each other to form an airway, so that the gas entering the air pump has a larger flow range, and finally flows out from the air flow dispersion port set in each horizontal heat dissipation slide. The heat dissipation distribution is more uniform, so that the heat can be quickly dispersed outside the cabinet, ensuring that the temperature of the electrical components during operation is kept within a safe range, thereby improving the stability and service life of the system, achieving the function of efficient heat dissipation while taking into account the replacement of the position of the electrical components.

[0018] (2) The rubber roll provided in the present invention changes the relative position and angle between the coil and the magnetic field through the principle of magnetoelectricity during the deformation of the coil in the closed circuit. The magnetic flux inside the coil will change, resulting in the generation of induced electromotive force. The electromotive force will drive the electrons to flow, forming an induced current. When the current flows, the light-emitting diode will turn on and illuminate. Therefore, when it is necessary to replace the wire, it is only necessary to hold the rubber roll and pull the wire to be replaced. When the wire to be replaced is pulled, the coil will be deformed, and the light-emitting diode next to the wire to be replaced will be lit, so that the position of the wire to be replaced in the wiring harness can be quickly found and replaced. During the replacement, the replacement process of the wire is more intuitive and convenient, which reduces the risk of misoperation and improves the operation efficiency.

[0019] (3) The cable clamp of the present invention can fix the rubber roll on the side wall of the cabinet to avoid clutter. At the same time, the buckling depth can be adjusted by setting the buckling end of the cable clamp, so as to fix rubber rolls of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

The multiple horizontal heat dissipation slides 220 are horizontally fixed on the inner wall of the cabinet 100. The horizontal heat dissipation slides 220 are fixedly connected by the vertical heat dissipation slides 230, and the top of the vertical heat dissipation slide 230 abuts against the top of the cabinet 100, and the bottom abuts against the bottom of the cabinet 100; an air pump 500 is installed on the top of the cabinet 100, and the air outlet of the air pump 500 is connected to the vertical heat dissipation slide 230; a sliding block 210 is slidably installed on the horizontal heat dissipation slide 220, and electrical components are fixedly installed on the sliding block 210.

[0025] The outlet air of the air pump 500 flows into the heat dissipation slide 200 and is dispersed to various places in the cabinet 100 through the heat dissipation slide 200 to dissipate heat and cool down. At the same time, a sliding block 210 is also installed on the heat dissipation slide 200. The electrical components are fixed on the sliding block 210. The installation position of the electrical components can be replaced by sliding the sliding block 210, which is convenient for adjustment. At the same time, it can prevent the problem of difficulty in changing the position due to fixing on the cabinet when wiring is inconvenient and needs to be replaced, thereby achieving the function of efficient heat dissipation while taking into account the replacement of the position of electrical components.

[0026] In this embodiment, the cross-sections of the horizontal heat dissipation slide 220 and the vertical heat dissipation slide 230 are both C-shaped slots, and protrusions 241 are provided on the two side walls inside the slots of the horizontal heat dissipation slide 220 and the vertical heat dissipation slide 230. Strip rubber pads 242 are fixed on both sides of the slots of the horizontal heat dissipation slide 220 and the vertical heat dissipation slide 230, and the sides of the strip rubber pads 242 at both ends that are close to each other fit together.

[0027] Strip rubber pads 242 are fixed at the notches of the horizontal heat dissipation slide 220 and the vertical heat dissipation slide 230, so that the top notch of the heat dissipation channel is in a closed state, forming a channel for dispersed airflow. When the sliding block 210 is slidably installed on the heat dissipation channel 200, the strip rubber pads 242 at the sliding position of the sliding block 210 are squeezed, which will not cause the sliding block 210 to be unable to slide. Moreover, the strip rubber pads 242 are squeezed, which can make the sliding block 210 stay more stably when it is not moving.

[0028] In this embodiment, interfaces 221 are opened on both sides of the middle part of the horizontal heat dissipation slide 220, and the vertical heat dissipation slide 230 is connected with both sides of the horizontal heat dissipation slide 220 through the interface 221. Both sides of the interface 221 are provided with a first fan-shaped connecting block 223 extending from the protrusion 241 and a second fan-shaped connecting block 222 extending from the groove.

[0029] The arrangement of the first fan-shaped connecting block 223 and the second fan-shaped connecting block 222 allows the horizontal heat dissipation slide 220 and the vertical heat dissipation slide 230 to be more closely connected. At the same time, the sliding block 210 can change the sliding direction at will when passing through the interface 221. The electrical components can be adjusted to the corresponding horizontal heat dissipation slide 220 as needed, making the position adjustment of the electrical components more convenient.

[0030] In this embodiment, the sliding block 210 includes a sliding plate 211, and grooves 212 are opened on both sides of the sliding plate 211. The grooves 212 cooperate with the protrusions 241. A sliding column 213 is fixed to the upper end of the sliding plate 211. The sliding column 213 is slidably connected to the C-shaped groove and is squeezed and connected to the strip rubber pad 242; a fixed block 214 is fixed to the top of the sliding column 213, and an electrical component is fixed to the fixed block 214.

[0031] In this embodiment, an air passage 243 is formed between the bottom surface of the sliding block 210 and the bottom of the slot of the heat dissipation slide 200 .

[0032] The provision of the air passage 243 ensures that the dispersion of the air flow will not be hindered by the installation of the sliding block 210 .

[0033] In this embodiment, a plurality of airflow dispersion openings 224 are evenly distributed on the two side walls of the horizontal heat dissipation slide 220. The airflow dispersion openings 224 on both sides of the interface 221 are symmetrically arranged. The airflow dispersion openings 224 are oblique openings, and the oblique opening direction of the airflow dispersion openings 224 expands outward along the airflow direction.

[0034] The oblique opening direction of the airflow dispersion port 224 expands outward along the airflow direction, making the cold air distribution more convenient and uniform.

[0035] In this embodiment, the cable clamp 300 includes a lower clamp 310 and an upper clamp 320, and both the lower clamp 310 and the upper clamp 320 are arc-shaped. Rubber pads 340 are fixed to the inner sides of the arcs of the lower clamp 310 and the upper clamp 320. A fixing column 311 is provided at the bottom of the lower clamp 310, and the cable clamp 300 is fixedly connected to the inner wall of the cabinet 100 through the fixing column 311; one end of the lower clamp 310 is rotatably connected to one end of the upper clamp 320, and the other end of the lower clamp 310 is buckled with the other end of the upper clamp 320.

[0036] The lower clamping piece 310 and the upper clamping piece 320 are clamped to fix the wire harness.

[0037] In this embodiment, a horizontal plate 312 is provided at the buckling end of the lower clamp 310, and a first through slot 313 is provided on the horizontal plate 312. A transverse slot 314 is also provided on the horizontal plate 312, and the transverse slot 314 is located on the side of the first through slot 313 away from the fixed column 311, and the transverse slot 314 is connected to the first through slot 313; a second through slot 315 is provided on the transverse slot 314; a slider 316 is slidably connected in the transverse slot 314, and a shift block 317 is fixed on the slider 316, and the shift block 317 extends out of the horizontal plate 312 through the second through slot 315, and a spring 318 is fixedly connected to one end of the slider 316 away from the first through slot 313, and the other end of the spring 318 abuts against the side wall of the transverse slot 314; a buckling strip 321 is provided at the buckling end of the upper clamp 320, and a buckling tooth 322 is provided on the buckling strip 321.

[0038] When buckling, the buckle strip 321 is inserted into the first through groove 313. Due to the tension of the spring, the other end of the slider 316 abuts against the buckle tooth 322 to limit the buckle tooth 322. At this time, the buckle is fixed. When it is necessary to unlock, the block 317 is pushed toward the end of the spring 318. The spring 318 is compressed, and the part of the slider 316 extending out of the transverse groove 314 slides into the transverse groove 314. The slider 316 cancels the limitation on the buckle tooth 322. At this time, the buckle strip 321 is pulled out of the first through groove 313 to unlock.

[0039] In this embodiment, the rubber roll 400 is formed by curling a rubber strip 410, and a plurality of through holes 411 are evenly distributed in the extension direction of the rubber strip 410. An inductor 412 is fixed on the inner wall of the through hole 411. A light-emitting diode 413 is also fixed on the rubber strip 410 located on one side of each through hole 411. The two ends of the inductor 412 are electrically connected to the light-emitting diode 413 to form a closed circuit. Permanent magnets 414 are installed in the rubber strips 410 located on both sides of the inductor 412; and an electric wire is passed through the inner side of the inductor 412.

[0040] The through hole 411 opened on the rubber strip 410 is for passing the wire. A wire is installed in one through hole 411, and the wire is wrapped by the inductor 412 fixed on the inner wall of the through hole. After the wire is installed, it is rolled into a rubber roll 400 and fixed. When the electrical component or the wire needs to be replaced, according to the principle of magnetoelectricity, it is only necessary to hold the rubber roll 410 and pull the wire to be replaced. When the wire to be replaced is pulled, the inductor 412 is deformed. In the process of deformation of the coil in the closed circuit, its relative position and angle with the magnetic field are changed, and the magnetic flux inside it will change, resulting in the generation of induced electromotive force. The electromotive force will drive electrons to flow and form an induced current. When the current flows, the light-emitting diode 413 will be turned on and illuminated, so that the position of the wire to be replaced in the wiring harness can be quickly found and replaced, with excellent effect.

[0041] Furthermore, it should be noted that the direction of the induced current is consistent with the conduction direction of the light emitting diode 413 .

[0042] In this embodiment, a heat dissipation opening is provided on the cabinet 100 .
