Description

Technical Field

[0001] This utility model relates to the field of electrical control switch technology, and in particular to a switch box. Background Technology

[0002] In outdoor parks, gardens, ponds, and other areas, water pumps and other electrical components are currently installed using long, continuous wiring. This makes it difficult to add or modify wiring in the existing environment, leading to on-site construction difficulties. Each change or repair requires rewiring, resulting in long construction times and high costs. Therefore, switch boxes (distribution boxes) are now commonly used in the market for centralized wiring, achieving a more organized and manageable wiring system.

[0003] Functionally, current switch boxes are all in the form of a main switch connected to N small switches. This structure is too simple and only has the function of controlling opening and closing. It cannot realize the monitoring function for some electrical products. Therefore, the switch boxes used in the past are too simple in function and cannot meet the current demand for expansion.

[0004] Structurally, current switch boxes typically require operators to use simple wire clamps to secure cables, which is cumbersome and inefficient. Furthermore, the main body of the switch box is merely a frame, and structural defects and insufficient sealing can easily lead to damage or short circuits in the internal electrical components. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned defects in the prior art and provide a switch box that can realize individual programming and monitoring of each connected electrical component. It can be used with LED lights to display different colored lights to show different operating states, which makes it convenient for maintenance personnel to quickly identify problematic components and improve maintenance efficiency. At the same time, the independent sealed cavity can protect the internal circuit boards and controllers to avoid interference and effectively prevent dust, moisture and other substances from entering, thus improving the dustproof and waterproof performance of the switch box.

[0006] To achieve the above objectives, this utility model provides a switch box, comprising: a main box body and an upper cover body;

[0007] The main box and the upper cover are hinged on one side, and a closing structure is provided on the other side for opening and closing control.

[0054] Brief description of the working principle of this utility model:

[0055] The opening and closing of the upper cover 2 of this utility model is as follows: First, remove the screws from the first locking threaded hole 422 and the second locking threaded hole 418 to unlock the locking member 42. Then, a long stick or a small screwdriver can be inserted into the second through hole 15 to push the locking member 42 open, so that the first locking hook 421 and the second locking hook 28 are disengaged, and the upper cover 2 can be opened.

[0056] Cable connection: First, loosen the screw nut 31 and the fixing piece 62. Then, pass the cable through the screw nut 31, the threaded screw 32 and the connecting part 19 into the main box 1. Then, open the wiring assembly 13 and insert the copper wire of the cable into the wiring assembly 13 and lock it. Then, place the cable on the cable fixing base 61, press the fixing piece 62 with the screw to lock the cable on the cable fixing base 61, and finally, turn the screw nut 31 to tighten it to complete the cable installation.

[0057] Functional Expansion: The PLC controller 23 can be programmed to control the functions of each device connected to the wiring component 13. It can be used with various controllers / modules to expand the functions. For example, it can be used with the control switch 25 to control opening and closing, or with the timer and power consumption monitor / module to monitor the timing and power consumption of the connected electrical components. Taking the connection of a water pump as an example, when a new water pump is connected for the first time, the PLC controller 23 controls the timer and power consumption monitor / module to monitor the connected water pump in real time all day. If the power consumption is too high and exceeds the threshold, or if there is continuous connection and disconnection, causing the calculator to reset a certain number of times, the power will be cut off and the LED 221 will light up red, indicating that there is a problem with the water pump and reminding the staff to check it.
