Description

Technical Field

[0001] This patent relates to a power automation device, specifically a modular plug-in box. Background Technology

[0002] Currently, low-voltage cable distribution boxes or power boxes on the market all use fixed-installation low-voltage molded case circuit breakers with copper busbar conductive connections for their outgoing lines. Furthermore, they are designed with multiple circuits as backup circuits. When a fault occurs in one outgoing line, the entire low-voltage cable distribution box or power box needs to be de-energized for maintenance, leading to a large-scale power outage or ineffective power outages in other circuits, thus increasing losses. Moreover, the existence of backup circuits also results in a significant waste of resources. Utility Model Content

[0023] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] Currently, low-voltage cable distribution boxes or power boxes on the market all use fixed-installation low-voltage molded case circuit breakers with copper busbar conductive connections for their outgoing lines. Furthermore, they are designed with multiple circuits as backup circuits. When a fault occurs in one outgoing line, the entire low-voltage cable distribution box or power box needs to be de-energized for maintenance, leading to a large-scale power outage or ineffective power outages in other circuits, thus increasing losses. Moreover, the existence of backup circuits also results in a significant waste of resources.

[0025] This patented modular plug-in box enables replacement and maintenance while the circuit is energized, meaning that replacing one circuit does not affect the normal operation of other circuits. Furthermore, the number of circuits can be increased or decreased at any time according to user needs, reducing user costs and conserving resources. The internal switches adopt a segmented design, with three low-voltage molded case circuit breakers (i.e., one) in each segment. Each segment can be disassembled and reassembled as needed; each molded case circuit breaker can be flexibly disassembled and reassembled while the circuit is energized, ensuring operator safety. The plug-in box also takes into account various operating environments, providing multiple cable entry and exit holes.

[0026] First, the overall structure of this patented modular plug-in box, such as... Figures 1-3Its appearance is that of a rectangular box with two doors. The outer door is on the front of the box. After opening the outer door, there is also an inner door to ensure safe operation. The inner door has a slot to expose the switch contact box 10. When in use, the outer door is opened, and the opening or slot on the inner door exposes the switch contact box 10. There is a label frame 9 on one side of the switch contact box 10 to facilitate the user to operate according to the label.

[0027] The specific configuration is as follows: the upper side of the cabinet is equipped with a cable inlet 1, the interior of the cabinet is divided into two layers, with a left outer door 2, a right outer door 3, an outer door lock 4, and a frame 5 at the bottom of the cabinet;

[0028] The side of the enclosure is equipped with inlet / outlet knockout holes 7, which can be set as needed for inlet / outlet cable configuration; the top is equipped with a lifting ring 6.

[0029] The internal structure of the enclosure, such as Figure 4 Open the outer door of the plug-in box to see the upper and lower sections inside the box. The upper section has an upper left door 11 and an upper right door 13. A switch panel 12 is located between the upper left and right doors. The lower section has an inner left door 8 and an inner right door 15. A label frame 9 is located on the lower section. A switch contact box 10 and a data box 14 are also provided.

[0030] Normally, with the outer door open and the inner door closed, users can safely perform routine operations on the junction box. For example, it allows for replacement and maintenance while the circuit is energized, meaning that replacing one circuit does not affect the normal operation of other circuits.

[0031] like Figure 5 If additional circuits are needed, there is no need to cut or drill holes in the cabinet; it is plug-and-play, requiring no on-site construction work.

[0032] The specific operation is as follows: After the user further opens the inner door of the box, a busbar 16, a mounting beam 17, and a contact box mounting plate 18 can be seen in the space behind the door. At this time, the switch contact box 10 can be quickly removed using a screwdriver.

[0033] Figure 6 , Figure 7 A separate busbar 16 is shown, with an insulating housing 19 on its outer side; the housing 19 has slots 20 on its side.

[0034] like Figure 7 The side of the housing 19 is provided with a slot 20, which is shaped like a grid hole, to facilitate the installation and fixing of the switch contact box 10.

[0035] like Figure 8 , Figure 9 , Figure 10 The patent further illustrates the independently detachable switch contact box 10, which is an insulating component that fixes, isolates, and protects the moving / stationary contacts of electrical appliances.

[0036] This part constitutes an independent plug-in unit. It allows for uninterrupted replacement of the main circuit, capacity expansion, and standardized modular design, avoiding mis-insertion and mis-replacement. Operation is simple, requiring no special tools; a regular flathead screwdriver can easily complete the task. Simply insert the screwdriver into the disassembly hole 21 for quick disassembly and installation.

[0037] First, the switch contact box 10 is fixed on the fixing plate 23, which has mounting holes 21 and hooks 22. When an additional circuit is needed, there is no need to cut or drill holes in the cabinet; it is plug-and-play. The switch is inserted into the grille hole (slot) of the outer shell 19. The grille hole acts as a slot and connects to the busbar 16, eliminating the need for on-site construction.

[0038] When the switch contact box 10 is inserted, the hook 22 of its lower fixing plate 23 can be inserted into the slot of the contact box mounting plate 18 for fixation. When it is necessary to remove the switch contact box 10, the independent plug-in unit enables uninterrupted replacement and capacity expansion of the main circuit using a standardized modular design, avoiding misinsertion and replacement. The operation is simple and requires no special tools; it can be easily completed with a regular flathead screwdriver. Simply insert the screwdriver into the mounting hole 21 and gently pry it open to disengage the hook 22 from the mounting plate for quick disassembly and installation.

[0039] The contact box mounting plate 18 is fixed inside the enclosure.

[0040] like Figure 12 Considering the complex working conditions on site, the equipment allows for cable entry and exit from either the top, bottom, left, or right (dual cable exit) or either the top, bottom, or right (single cable exit) directions. The cable entry and exit holes are knockout holes, allowing users to choose the appropriate cable entry and exit method based on site conditions, ensuring flexibility and convenience in construction.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of this patent, and not to limit them; although this patent has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this patent.
