Description

Technical Field

[0001] This utility model relates to a modular assembly and disassembly structure with a plug-in design that facilitates rear wiring. Background Technology

[0002] In power transmission, distribution, and control equipment, junction boxes are typically used to install electronic devices. Existing junction box mechanisms are generally open on one side, with the other three sides sealed by baffles. Electronic devices are installed one by one inside the junction box. This structure requires distinguishing each electronic device during wiring, which can easily lead to confusion if there are many devices, and is inconvenient for later wiring and maintenance. Therefore, it is necessary to improve the existing junction boxes to solve the above problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a modular assembly and disassembly structure that is easy to connect to the back-end wiring.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a modular assembly and disassembly structure for easy rear wiring, including a support frame and at least one modular device. The support frame is composed of four parallel square tube columns. At least one set of slide rail brackets is installed between the square tube columns on the left and right sides. The number of slide rail brackets is the same as the number of modular devices. Each modular device is pulled out and installed on a set of slide rail brackets. The modular device includes a modular mounting frame, at least one first rack device and at least one second rack device. The modular mounting frame includes a base plate, a front frame and side baffles. Multiple layers of side baffles are stacked from bottom to top on both sides of the base plate. The bottom of the inner side of the side baffles on both sides is provided with a support edge. A set of side baffles on the left and right sides forms a receiving cavity for accommodating rack devices. Each first rack device and each second rack device are respectively placed in a receiving cavity and supported on the support edge at the bottom. The front frame is set in front of the side baffles and is fixedly connected to the base plate and the side baffles. The middle part of the front frame is provided to facilitate the installation of rack devices. Based on function and requirements, each device is modularized, allowing for the complete disassembly and installation of the same module, while different modules can be disassembled and installed separately, facilitating wiring and maintenance. Simultaneously, the entire support frame and the modular equipment need to be enclosed within a housing. In existing technologies, rack-mounted equipment is directly mounted on the support frame, requiring a maintenance window to be reserved at a corresponding location on the housing due to rear wiring. However, in this invention, each module can be removed individually, eliminating the need for a maintenance window at the rear of the housing. This means no maintenance point is required at the rear of the housing, and only the module requiring maintenance needs to be disassembled, without disassembling the entire device, thus reducing costs and improving maintenance efficiency.

[0005] Furthermore, each set of slide rail brackets includes two opposing left and right side plates, each with a guide rail on its inner side. The front end of each side plate has an outward-flared edge with multiple first connection holes. Composed of two side plates, the design is open vertically and horizontally, without obstruction, facilitating both rear-end wiring and heat dissipation. The slide rail connection method makes support, connection, and disassembly convenient, and the structure is simple.

[0006] Furthermore, in order to facilitate the modular equipment to be fixed on the support frame, a connecting plate is provided on both the left and right sides of the front frame. The connecting plate is folded outward and has multiple second connecting holes on the folded part. During assembly, the second connecting holes and the first connecting holes are aligned one by one and locked with mounting screws to fix the modular mounting frame to the slide rail bracket.

[0007] Furthermore, in order to fix the rack equipment on the modular mounting frame, a third connecting hole is provided on the left and right sides of the front frame. The third connecting hole cooperates with the connecting holes on the first rack equipment and the second rack equipment, and the first rack equipment and the second rack equipment are locked on the modular mounting frame by mounting screws.

[0008] Furthermore, the rear end of the side baffle is provided with a side guard edge, and the left, right, and rear ends of the bottom plate are provided with bottom guard edges. The guard edges improve safety during assembly and also act as a limit, preventing the frame equipment from being pushed in excessively during assembly.

[0009] Furthermore, the rear end of the base plate protrudes beyond the side baffle. The length of the rear end of the base plate is greater than that of the side baffle, leaving a section for temporary placement of cables, screws, tools, etc. during wiring and installation, and for catching fallen parts to prevent loss; at the same time, it also serves as a limit, leaving some space at the rear end of the modular equipment for heat dissipation.

[0010] Preferably, there are two rack devices.

[0011] The beneficial effects of this utility model are: the modular disassembly and assembly structure of the plug-in type that facilitates rear wiring is a modular installation and maintenance method for rear wiring equipment. The modular installation facilitates operation and maintenance; there is no need to set up maintenance points at the rear of the casing, thus reducing costs. Attached Figure Description
