Description

Technical Field

[0001] The utility model relates to the field of cabinets, in particular to a pluggable and assembled cabinet. Background Art

[0002] At present, the main form of power cabinets with compartments is integral cabinets, which are divided into 2 - 3 compartments, and electrical components are respectively installed inside different compartments according to different functional areas. There are also some devices that integrate special functional areas into an embedded module and install it in the integral cabinet. This structure makes the production and assembly process in the same cabinet, with small operating space, which is not conducive to parallel operation of multiple people and multiple installation processes. And when replacing devices on site, it is necessary to disassemble and assemble internal components or embedded modules in a narrow space, which is not conducive to on-site maintenance.

[0003] In the main circuit and control part of some devices, or in the power distribution module and power module of the device, placing them in separate compartments is more conducive to ensuring safety regulations and facilitating device maintenance. For example, the traditional pole-mounted integrated distribution box (JP cabinet) often adopts a left-right compartmentalized integrated structure, placing the primary power distribution part and the monitoring and metering part in different compartments respectively.

[0004] While the indoor integrated distribution box (GGD) usually places the metering and power distribution cabin equipment in the same cabinet compartment, with an independent compartment made of sheet metal in the middle and the cabinet door made of a segmented structure. This kind of device needs to be strictly produced according to a certain technological process during production, which is not conducive to division of labor and cooperation. When some devices on site fail and need to be replaced, due to the small on-site maintenance space, especially when maintaining pole-mounted equipment, the disassembly, assembly and wiring work are more difficult. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the background art, and propose a pluggable and assembled cabinet. The cabinet is made into a split structure that can be assembled on site. The sub-cabinets can be placed on different production lines for production, realizing parallel installation processes. The compartments of the control part or the power part can be replaced as a whole, reducing the maintenance difficulty.

[0006] The technical solution of the utility model, a pluggable and assembled cabinet, includes a plurality of sub-cabinets arranged side by side in the vertical or horizontal direction and detachably connected in sequence. One end of the sub-cabinet facing the adjacent sub-cabinet is provided with strong electrical terminals and weak electrical terminals, and the adjacent sub-cabinet has an opening for the strong electrical terminals and weak electrical terminals to move into.

[0007] Preferably, the plurality of sub-cabinets are sequentially connected by bolts.

[0008] Preferably, the strong electrical terminal is a strong electrical through-type large current terminal, and the weak electrical terminal is a circuit board or a pluggable weak electrical through terminal.

[0009] Preferably, the high-voltage terminals and the low-voltage terminals are respectively replaced with pluggable male connectors and female connectors.

[0010] Preferably, a waterproof rubber strip is arranged along the edge of the opening.

[0011] Preferably, the sub-cabinet includes a cabinet body and a cover plate, and the cover plate is detachably connected to the cabinet body.

[0012] Preferably, the sub-cabinet includes a cabinet body and a cabinet door, the cabinet door is connected to the cabinet body through a hinge, and a door lock is arranged on the cabinet door.

Specifically, the two sub-cabinets a1 can be connected in sequence by bolts. The number of sub-cabinets a1 can be expanded to multiple (more than 2), and the multiple sub-cabinets a1 are arranged side by side and detachably connected by bolts. For equipment that needs regular maintenance, it is installed in the top sub-cabinet a1.

The strong electrical terminal a11 and the weak electrical terminal a12 can also be replaced by a pluggable male head and female head respectively, which can realize the one-time plugging and unplugging of the equipment and eliminate the step of removing bolts.

[0026] The sub-cabinet a1 includes a cabinet body and a cover plate, and the cover plate is detachably connected to the cabinet body, or is snap-connected or fixedly connected. Or the sub-cabinet a1 is designed to include a cabinet body and a cabinet door, the cabinet door is connected to the cabinet body by a hinge, and a door lock is arranged on the cabinet door.
