Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, specifically a power distribution box structure. 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] In one type of existing distribution box, the circuit breaker and other components are all located on one side of the distribution box, while the cables run through the box and connect to the circuit breaker and other components from inside the box. During maintenance, the side where the circuit breaker and other components are installed needs to be completely removed in order to repair and maintain the cables and other components inside the box. The removal process will pull on the internal cables, which is very inconvenient.

[0004] In view of this, there is an urgent need for a distribution box structure 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 distribution box structure includes: a front frame, a back frame, a back panel, a front panel, two side frames, and two side panels. The two side frames and the two side panels are disposed between the front frame and the back frame. The two side frames are arranged opposite to each other, and the two side panels are arranged opposite to each other. The two side panels are respectively disposed on both sides between the two side frames. The front panel is disposed on the side of the front frame away from the back frame, and the back panel is disposed on the side of the back frame away from the front frame. The front frame, back frame, back panel, front panel, two side frames, and two side panels enclose an installation space.

[0008] The panel is equipped with several circuit breakers, and the back frame is equipped with several cable through holes.

[0009] The side plate is not connected to the side frame. Several fastening bolts are provided on both sides of the side plate, and the side plate is connected to the front frame and the back frame respectively through the several fastening bolts.

[0010] The fastening bolts are inserted into the corresponding side plate from the side away from the installation space.

[0011] The face frame is ring-shaped.

[0012] The back frame is ring-shaped.

[0013] The back panel is mesh-like.

[0014] The front frame and the side frame, the back frame and the side frame, the back plate and the back frame, and the front frame and the panel are all connected by mounting bolts.

[0015] Several cable perforations are respectively provided on both sides between the two side plates.

[0016] All cable perforations are fitted with plugs.

[0017] Connectors are provided between the side plate and the front frame and the back frame. Each connector includes a first connecting plate and a second connecting plate. The first connecting plate and the second connecting plate are arranged perpendicularly to each other. The first connecting plate is disposed on the front frame or the back frame. A plurality of fastening bolts are threadedly connected to the second connecting plate.

[0018] The installation space is rectangular in shape.

[0019] The above-described structure of this utility model can achieve the following beneficial effects:

[0020] In use, the cable is threaded through the cable hole into the installation space and connected to the circuit breaker and other structures on the panel. Since the side plate is located between the front frame and the back frame, when maintenance is required in the installation space, simply tighten the bolts to remove the side plate. The components in the installation space can then be operated directly from both sides without removing the panel containing the circuit breaker and other structures. This avoids pulling on the internal cables and improves the convenience of disassembly and maintenance. Attached Figure Description

[0029] 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.

[0030] 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.

[0031] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0032] like Figures 1-4 As shown, a distribution box structure includes: a front frame 1, a back frame 2, a back panel 3, a front panel 4, two side frames 5, and two side panels 6. The two side frames 5 and the two side panels 6 are both disposed between the front frame 1 and the back frame 2. The two side frames 5 are arranged opposite each other, and the two side panels 6 are arranged opposite each other. The two side panels 6 are respectively disposed on both sides between the two side frames 5. The front panel 4 is disposed on the side of the front frame 1 away from the back frame 2, and the back panel 3 is disposed on the side of the back frame 2 away from the front frame 1. The front frame 1, the back frame 2, the back panel 3, the front panel 4, the two side frames 5, and the two side panels 6 enclose an installation space.

[0033] Several circuit breakers 7 are installed on the panel 4, and several cable through holes 21 are installed on the back frame 2;

[0034] The side panel 6 is not connected to the side frame 5. Several fastening bolts 8 are provided on both sides of the side panel 6, and are connected to the front frame 1 and the back frame 2 respectively through several fastening bolts 8.

[0035] Based on the above structure, during use, the cable is passed through the cable through hole 21 into the installation space and connected to the circuit breaker 7 and other structures on the panel 4. Since the side plate 6 is located between the front frame 1 and the back frame 2, when maintenance is required in the installation space, the side plate 6 can be removed by tightening the fastening bolts 8. The components in the installation space can then be operated directly from both sides without removing the panel 4 containing the circuit breaker 7 and other structures. This avoids pulling on the internal cables and improves the convenience of disassembly and maintenance.

[0036] like Figure 1 As shown, the fastening bolt 8 is inserted into the corresponding side plate 6 from the side away from the installation space, which makes the head space of the fastening bolt 8 larger and improves the convenience of tightening the fastening bolt 8.

[0037] like Figure 1 and Figure 5 As shown, both the front frame 1 and the back frame 2 are ring-shaped to facilitate the installation of the side frames 5 and the side panels 6, thus forming an installation space.

[0038] like Figure 3 As shown, in order to improve heat dissipation, the back plate 3 is grid-shaped, that is, the back plate 3 is provided with several through holes to facilitate heat exchange between the installation space and the external environment.

[0039] Further optimization involves connecting the front frame 1 and side frame 5, the back frame 2 and side frame 5, the back panel 3 and back frame 2, and the front frame 1 and panel 4 with mounting bolts to facilitate assembly of the enclosure. If any component is damaged, only the damaged part needs to be replaced.

[0040] Further optimizations include, for example Figure 5 and Figure 6 As shown, several cable holes 21 are respectively set on both sides between the two side plates 6. In this way, when the side plates 6 are removed, the cables are distributed on both sides and will not interfere with the operation of maintenance personnel. In addition, each cable hole 21 is provided with a plug 22. When it is necessary to thread the cable, the plug 22 is removed, the cable is threaded in, and the empty cable hole 21 is sealed to prevent the cable hole 21 from being too large and causing foreign objects to enter the box.

[0041] like Figure 6 and Figure 7 As shown, a connector 9 is provided between the side panel 6 and the front frame 1 and the back frame 2. The connector 9 includes a first connecting plate 91 and a second connecting plate 92. The first connecting plate 91 and the second connecting plate 92 are arranged perpendicular to each other. The first connecting plate 91 is set on the front frame 1 or the back frame 2. Several fastening bolts 8 are threadedly connected to the second connecting plate 92. The side panel 6 is installed through the first connecting plate 91 and the second connecting plate 92.

[0042] A further optimization is that the installation space in this embodiment is rectangular.

[0043] In summary, during use, the cable is threaded through the cable hole 21 into the installation space and connected to the circuit breaker 7 and other structures on the panel 4. Since the side plate 6 is located between the front frame 1 and the back frame 2, when maintenance is required in the installation space, the side plate 6 can be removed by tightening the fastening bolts 8. The components in the installation space can then be operated directly from both sides without removing the panel 4 containing the circuit breaker 7 and other structures. This avoids pulling on the internal cables and improves the convenience of disassembly and maintenance.

[0044] 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.
