Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a grounding terminal block device for power distribution cabinets. Background Technology

[0002] In power systems, distribution cabinets, as core equipment for power distribution and control, directly impact the safe and stable operation of the power system through the reliability of their grounding terminal blocks. Traditional distribution cabinet grounding terminal blocks often use screws to connect wires; however, this method has significant drawbacks. During long-term use, factors such as equipment vibration and changes in ambient temperature and humidity can cause the screws to loosen, leading to incomplete wire connections. This not only increases grounding resistance and affects grounding effectiveness but can also cause localized overheating and even pose a fire hazard. Furthermore, traditional terminal blocks have limited fixing force on wires, failing to effectively "lock" them in. Under significant external force, wires can easily detach from the terminal blocks, seriously threatening the safety of the power system.

[0003] Meanwhile, existing grounding terminal block junction boxes have poor protective performance, mostly only having basic dustproof functions, and are difficult to resist moisture, corrosive gases and external impacts. The electrical connection components inside the junction box are easily damaged by environmental factors, shortening the service life of the equipment and increasing maintenance costs and safety risks.

[0004] Therefore, this utility model provides a grounding terminal block device for a power distribution cabinet. Utility Model Content

[0029] like Figures 1 to 4As shown in the figure, a grounding terminal block device for a distribution cabinet according to an embodiment of the present invention includes a mounting plate 1; mounting holes 2 are provided on the surface of the mounting plate 1, a grounding body 3 is fixedly mounted on one side of the mounting plate 1, a junction box 4 is movably snapped onto the surface of the grounding body 3, a sliding mechanism 5 is provided on the inner wall of the junction box 4, and an adjusting component 6 is provided on the inner wall of the junction box 4; a wire pressing component 7 is provided on the side of the pressing plate 53 near the grounding body 3, and a guiding mechanism 8 is provided on the top of the pressing plate 53; a protective mechanism 9 is provided on the side of the mounting plate 1 near the junction box 4. The sliding mechanism 5 includes a rectangular slide groove 51, a sliding block 52, and a clamping plate 53. The rectangular slide groove 51 is formed on both sides of the inner wall of the junction box 4. The sliding block 52 is slidably installed on the inner wall of the junction box 4 through the rectangular slide groove 51. The inner wall of the sliding block 52 is fixedly installed with the clamping plate 53. The adjusting component 6 includes a cross nut 61 and a screw 62. Two sets of screws 62 are provided. The two sets of screws 62 are rotatably installed in the rectangular slide groove 51 formed on the inner wall of the junction box 4. The surface of the screw 62 is threadedly installed with the sliding block 52. The screw 62 is away from the sliding block 52. One end of the junction box 4 is fixedly installed with a cross nut 61. The wire clamping assembly 7 includes a corrugated clamping plate 71 and an insulating clamping plate 72. The corrugated clamping plate 71 is fixedly installed on the inner wall of the junction box 4 near the grounding body 3 and is in communication with the grounding body 3. The insulating clamping plate 72 is fixedly installed on the side of the clamping plate 53 near the corrugated clamping plate 71. The guide mechanism 8 includes a shaft bracket 81, a guide rod 82, and a limiting member 83. The shaft bracket 81 is fixedly installed on the top of the grounding body 3, and one side of the shaft bracket 81 is fixedly installed with the guide rod 82. The guide rod 82 is away from the shaft bracket 81. One end is fixedly installed with the limiting member 83, and the top of the clamping plate 53 is slidably installed on the surface of the guide rod 82. The protective mechanism 9 includes a fixing block 91, a T-shaped slider 92 and a protective cover 93. The fixing block 91 is provided in two sets, and the two sets of fixing blocks 91 are fixedly installed on both sides of the mounting plate 1 near the junction box 4. The T-shaped slider 92 is slidably installed on the inner wall of the fixing block 91. The side of the T-shaped slider 92 away from the fixing block 91 is fixedly installed with the protective cover 93. An indicator label 100 is affixed to the side of the clamping plate 53 away from the insulating pressure plate 72.

[0030] like Figures 1 to 4As shown, the rectangular groove 51 allows the sliding block 52 to slide stably on the inner wall of the junction box 4, ensuring the smooth movement of the clamping plate 53. The cooperation between the sliding block 52 and the clamping plate 53 enables movement via the screw 62 and clamps the wires via the insulating pressure plate 72, preventing them from falling off or loosening. The cooperation between the Phillips nut 61 and the screw 62 allows the user to rotate and drive the sliding block 52 and the clamping plate 53 to move, clamping the wires and ensuring stability after wiring. The cooperation between the corrugated pressure plate 71 and the insulating pressure plate 72 firmly fixes the wires through mutual interlocking. Since both the corrugated pressure plate 71 and the insulating pressure plate 72 are uneven, even if some wire ends become loose, it will not affect the normal contact between the wires and the corrugated pressure plate 71. To effectively prevent fires caused by poor contact, the combined use of the shaft bracket 81, guide rod 82, and limiting component 83 provides a limit to the movement of the pressure plate 53, allowing it to slide smoothly. This also facilitates electrical maintenance by the technician. The limiting component 83, connected to the grounding electrode 3, allows the technician to monitor the voltage of the grounding electrode 3 simply by using a multimeter. The combined use of the fixing block 91, T-shaped slider 92, and protective cover 93 provides protection for the junction box 4, preventing water leakage when the distribution box is used outdoors, which could affect its normal operation. It also isolates other wires, preventing the generation of magnetic fields and heat. The indicator label 100 allows users to easily name and manage the wires, making it clear how the wiring is planned during maintenance or electrical modifications.

[0031] Working principle: During operation, first place the mounting plate 1 inside the distribution box, then fix the mounting plate 1 inside the distribution box through the mounting hole 2. Then, the user inserts the wire end into the junction box 4 from the bottom. Next, use a tool to tighten the Phillips head nut 61. When the Phillips head nut 61 is tightened, it will drive the screw 62 to rotate. When the screw 62 rotates, it will cause the sliding block 52 on its surface to slide to one side. As the sliding block 52 continues to slide, the clamping plate 53 will drive the insulating pressure plate 72 to move towards the corrugated pressure plate 71 until the wire end is clamped. The special shape of the 2 allows them to interlock, firmly securing the copper wire and preventing loosening or poor contact at the wire end. The user then picks up the protective cover 93 and aligns the T-shaped slider 92 with the fixing block 91, then slides it from top to bottom onto the inner wall of the fixing block 91, so that the protective cover 93 can cover the junction box 4. After installation, the user writes the indicator mark on the indicator label 100 for easy identification of the corresponding wire during maintenance. When the user needs to measure the voltage during maintenance, they only need to align the test leads with the limit piece 83 to check the voltage of the grounding body 3.
