It includes: a cabinet body, with several first supports inside the cabinet, each first support having several terminals connected to an A-phase conductive plate, a B-phase conductive plate, and a C-phase conductive plate; three branch conductive plates are located on the side of the first supports away from the terminals; each A-phase conductive plate is connected to an A-phase branch conductive plate; each B-phase conductive plate is connected to a B-phase branch conductive plate; and each C-phase conductive plate is connected to a C-phase branch conductive plate.

Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a stable power distribution cabinet. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute electrical energy from a specific conductor in the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] Terminal blocks are an essential component of power distribution cabinets. Existing terminal blocks generally have three-phase interfaces, which are connected by three flexible conductive wires. However, because the flexible conductive wires are not easy to fix and are prone to tangling, they pose a safety hazard.

[0004] In view of this, there is an urgent need for a stable power distribution cabinet to solve the above problems. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stable power distribution cabinet includes: a cabinet body, wherein a plurality of first supports are provided inside the cabinet body, the plurality of first supports are horizontally arranged from bottom to top, and a plurality of wiring terminals are provided on the first supports;

[0008] The terminal block is connected to an A-phase conductive plate, a B-phase conductive plate, and a C-phase conductive plate. The A-phase conductive plate, the B-phase conductive plate, and the C-phase conductive plate are spaced apart. The first bracket is provided with three branch conductive plates on the side away from the terminal block. The three branch conductive plates are arranged in parallel in the horizontal direction. The three branch conductive plates are the A-phase branch conductive plate, the B-phase branch conductive plate, and the C-phase branch conductive plate, respectively.

[0009] Several of the A-phase conductive plates are connected to the A-phase branch conductive plates;

[0010] Several of the B-phase conductive plates are connected to the B-phase branch conductive plates;

[0011] Several of the C-phase conductive plates are connected to the C-phase branch conductive plates.

[0012] The first bracket is provided with a slide rail, and a plurality of the wiring terminals are snapped onto the slide rail;

[0013] The first bracket is provided with a fixing plate, which is U-shaped. Several terminals on the same slide rail are placed inside the fixing plate, and the two ends of the fixing plate are fixed to the first bracket by bolts.

[0014] A slot is provided on one side of the terminal block, and it is secured to the slide rail through the slot.

[0015] Both sides of the slide rail are provided with locking strips, and both sides of the wiring terminal are provided with locking plates. The two locking plates are respectively locked onto the side of the locking strip near the first bracket.

[0016] A first insulating pad is provided between the first bracket and the adjacent branch conductive plate, and between two adjacent branch conductive plates.

[0017] Two first insulating pads are provided between the first bracket and the adjacent branch conductive plate, and between two adjacent branch conductive plates. The two first insulating pads are respectively provided at both ends of the corresponding branch conductive plate.

[0018] A limiting plate is provided on the side of the three branch conductive plates away from the first bracket, and a second insulating pad is provided between the limiting plate and the adjacent branch conductive plate.

[0019] The first bracket has a second bracket at both ends, and the two second brackets are arranged in parallel. The two ends of the limiting plate are respectively arranged on the two second brackets.

[0020] Two second insulating pads are provided between the limiting plate and the adjacent branch conductive plate, and the two second insulating pads are respectively provided at both ends of the corresponding branch conductive plate.

[0021] The second bracket is fixed to the cabinet with bolts.

[0022] The second bracket is fixedly connected to the first bracket by bolts.

[0023] The above-described structure of this utility model can achieve the following beneficial effects:

[0024] Because the conductive plate has poor flexibility and is easy to fix, the three phases of several terminals are connected to the A-phase branch conductive plate, B-phase branch conductive plate and C-phase branch conductive plate respectively by the A-phase conductive plate, B-phase conductive plate and C-phase conductive plate arranged at intervals. This achieves isolation between the three phases, avoids contact or entanglement between the three phase lines, and avoids the generation of safety hazards.

[0025] Furthermore, the first insulating pad separates the first bracket and the three branch conductive plates from each other, preventing conductive plates of different phases from contacting each other and improving the stability of the distribution cabinet. Attached Figure Description

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0034] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0035] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0036] like Figures 1-4 As shown, a stable power distribution cabinet includes: a cabinet body 1, inside which are arranged a plurality of first supports 2, which are horizontally arranged from bottom to top, and slide rails 3 are provided on the first supports 2; a plurality of terminal blocks 4 are provided on the slide rails 3, and the terminal blocks 4 are snapped onto the slide rails 3; a fixing plate 9 is provided on the first supports 2, the fixing plate 9 is U-shaped, and the plurality of terminal blocks 4 on the same slide rail 3 are placed inside the fixing plate 9, the two ends of the fixing plate 9 are fixed to the first supports 2 by bolts, and the fixing plate 9 has openings adapted to the plurality of terminal blocks 4, so as not to interfere with the wiring of the terminal blocks 4. Thus, during installation, first, the terminal block 4 is clipped onto the slide rail 3, then the terminal blocks 4 on the slide rail 3 are aligned and brought together. Next, the fixing plate 9 is fitted onto the terminal block 4 from the side away from the slide rail 3. Finally, both ends of the fixing plate 9 are fixed to the first bracket 2, thus completing the fixing of several terminal blocks 4 on the slide rail 3. By clipping the terminal blocks 4 onto the slide rail 3, the terminal blocks 4 are initially positioned and installed. Then, by fixing several terminal blocks 4 on the same slide rail 3 with the fixing plate 9, not only is the stability of the terminal block 4 installation improved, but the convenience of installation is also enhanced.

[0037] like Figure 5 As shown, a slot 41 is provided on one side of the terminal block 4, and it is secured to the slide rail 3 through the slot 41. The specific securing structure can be as follows: both sides of the slide rail 3 are provided with a retaining strip 31, and both sides of the terminal block 4 are provided with a retaining plate 42. The two retaining plates 42 are respectively secured to the side of the retaining strip 31 near the first bracket 2. In this way, when installing the terminal block 4, the two retaining plates 42 are secured to the two retaining strips 31 from the top and bottom sides respectively, thus completing the fixation of the terminal block 4.

[0038] like Figure 2 , Figure 3 and Figure 6As shown, terminal 4 is connected to phase A conductive plate (called what in this art) 43, phase B conductive plate 44, and phase C conductive plate 45. Phase A conductive plate 43, phase B conductive plate 44, and phase C conductive plate 45 are spaced apart. On the side of the first bracket 2 away from terminal 4, three branch conductive plates 5 are provided (the branch conductive plates 5 are ultimately connected to what component?). The three branch conductive plates 5 are arranged parallel to each other in the horizontal direction. The three branch conductive plates 5 are phase A branch conductive plate, phase B branch conductive plate, and phase C branch conductive plate, respectively. A plurality of phase A conductive plates 43 are connected to phase A branch conductive plates; a plurality of phase B conductive plates 44 are connected to phase B branch conductive plates; and a plurality of phase C conductive plates 45 are connected to phase C branch conductive plates. Thus, the spaced-apart phase A conductive plates 43, phase B conductive plates 44, and phase C conductive plates... The conductive plate 45 connects the three phases of several terminals 4 to the A-phase branch conductive plate, B-phase branch conductive plate, and C-phase branch conductive plate respectively, achieving isolation between the three phases (the conductive plate has poor flexibility and will not swing easily), avoiding contact or entanglement between the three phase lines, and preventing the generation of safety hazards (if flexible wires contact or entangle, the lines will overheat, leading to safety hazards); and two first insulating pads 6 are provided between the first bracket 2 and the adjacent branch conductive plate 5, and between two adjacent branch conductive plates 5. The two first insulating pads 6 are respectively set at both ends of the corresponding branch conductive plate 5. The advantage of this arrangement is that the first insulating pads 6 separate the first bracket 2 and the three branch conductive plates 5 in pairs, preventing the conductive plates of different phases from contacting each other, thus improving the stability of the distribution cabinet.

[0039] like Figure 6 As shown, in order to improve the stability of the branch conductive plate 5 and the first insulating pad 6, a limiting plate 7 is provided on the side of the three branch conductive plates 5 away from the first bracket 2. Two second insulating pads 8 are provided between the limiting plate 7 and the adjacent branch conductive plate 5. The two second insulating pads 8 are respectively provided at both ends of the corresponding branch conductive plate 5. In this way, the limiting plate 7 and the first bracket 2 form a clamp to fix the three branch conductive plates 5. Furthermore, a second bracket 21 is provided at both ends of the first bracket 2. The two second brackets 21 are arranged in parallel. The two ends of the limiting plate 7 are respectively provided on the two second brackets 21. In this way, a U-shaped frame is formed, which makes the position of the three branch conductive plates 5 more stable and prevents them from shifting.

[0040] Further optimization involves fixing the second bracket 21 to the first bracket 2 with bolts to improve installation convenience, and fixing the second bracket 21 to the cabinet 1 with bolts, thus facilitating assembly, disassembly, and maintenance.

[0041] In summary, during installation, first, the terminal blocks 4 are snapped onto the slide rail 3, then the terminal blocks 4 on the slide rail 3 are aligned and brought together. Next, the fixing plate 9 is fitted onto the terminal blocks 4 from the side away from the slide rail 3. Finally, both ends of the fixing plate 9 are fixed to the first bracket 2, thus completing the fixing of several terminal blocks 4 on the slide rail 3. By snapping the terminal blocks 4 onto the slide rail 3, the terminal blocks 4 are initially positioned and installed. Then, by fixing several terminal blocks 4 on the same slide rail 3 with the fixing plate 9, not only is the stability of the terminal block 4 installation improved, but the ease of installation is also enhanced.

[0042] The three phases are isolated by using A-phase conductive plates 43, B-phase conductive plates 44 and C-phase conductive plates 45 arranged at intervals, and connecting the three phases of several terminals 4 to the A-phase branch conductive plates, B-phase branch conductive plates and C-phase branch conductive plates respectively. This avoids contact or entanglement between the three phase lines and prevents the generation of safety hazards.

[0043] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
