Description

Technical Field

[0001] This utility model relates to the field of plug-in box technology, and in particular to a quick and labor-saving hot-swappable plug-in box and its application in busbar trunking. Background Technology

[0002] A plug-in box is a power distribution control device used to connect cables and equipment, installed in electrical systems in industrial and commercial locations. It is an open box containing multiple sockets, typically used to connect electronic equipment and tools to meet various power needs. Existing plug-in boxes are mostly made of aluminum alloy, including a back panel and a front panel. Manufacturing a single box requires six sets of stamping dies to punch holes for corresponding parts, such as holes for various micro-circuit protection covers, lamp holes, various industrial socket holes, and communication interface holes from different monitoring manufacturers. The large number of dies makes the manufacturing process very cumbersome. Furthermore, the aluminum alloy box also has handles, gears, and other plastic parts on its side panels for fixing to busbars. Therefore, manufacturing a single plug-in box requires a wide variety of materials and a large number of standard screws. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a quick and labor-saving hot-swappable connector box and its application in busbar trunking, solving the problem of cumbersome manufacturing and processing techniques for connector boxes in the prior art.

[0005] A quick and labor-saving hot-swappable connector box includes a box body, which comprises a housing and a door panel. Both the housing body and the door panel are sheet metal parts. The front end of the housing body is open, and the opening end of the housing body has folded edges on all four sides. Rivet nuts are embedded on the folded edges on both sides of the housing body. The four sides of the door panel are continuously bent inward to form a retaining edge. The door panel is located at the opening of the housing body, and the retaining edge is fitted to the folded edge of the housing body. The door panel is connected and fixed to the housing body by screws passing through the retaining edges on both sides and being screwed to the rivet nuts.

[0006] The top of the enclosure has a through hole on one side for installing power terminals, and an upper through hole on the other side of the top of the enclosure. A lower through hole is located directly below the upper through hole at the bottom of the enclosure. A through wire runs longitudinally through the upper and lower through holes. The top of the through wire is fixedly connected to a rotating plate at the top of the enclosure for engaging and positioning with the bottom of the busbar. The bottom of the through wire is fixedly connected to a handle nut for rotating the through wire, and a butterfly nut is threaded onto the bottom of the through wire. The butterfly nut fits snugly against the bottom of the enclosure and is used to fix the position of the through wire.

[0007] Furthermore, the top of the box is recessed downwards at the location of the upper perforation to form a groove for accommodating the rotating card plate.

[0008] Furthermore, the rotating plate has rounded corners on both sides.

[0009] Furthermore, a micro-broken guide rail bracket and a terminal block bracket are respectively provided on the inner wall of the rear end of the housing.

[0010] Furthermore, the door panel has several mounting openings of different sizes and shapes, as well as screw holes around each mounting opening.

[0011] Furthermore, several rivet screws are vertically arranged on the inner wall of the box and the inner wall of the door panel for installing various components.

[0012] Another objective of this utility model is to provide a busbar trunking system, including a busbar trunking body and a plug-in box installed at the bottom of the busbar trunking body, wherein the plug-in box is a plug-in box of any of the above-mentioned technical solutions.

[0013] The beneficial effects of this utility model are reflected in:

[0014] (1) The plug-in box of this utility model adopts a sheet metal box body. The processing process is simplified by laser cutting, bending and welding, which reduces the number of molds and material types, meets the requirements of different shapes or different component configurations, and has a high degree of customization.

[0015] (2) This utility model uses a through-threaded nut and a rotating clamping plate to achieve quick and labor-saving fixing of the plug-in box and the busbar trunking, which significantly improves the assembly efficiency. Attached Figure Description

[0043] When installing the plug-in box with the busbar trunking, align the top of the plug-in box with the bottom opening of the busbar trunking. First, rotate the power terminal 6 on one side of the top of the plug-in box to screw the wing plate 61 on the power terminal 6 into the slot 51 of the busbar trunking for positioning. Then, rotate the handle nut 43 on the other side of the top of the plug-in box to screw the rotating plate 42 into the slot 51 of the busbar trunking for fixation. Finally, tighten the butterfly nut 44 to make it fit against the bottom of the box and lock the through thread 41 and the rotating plate 42 to prevent them from moving, thereby stably fixing the busbar trunking to the bottom of the busbar trunking.

[0044] The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model.
