Technical Field

[0001] The utility model relates to the technical field of cabinet production and manufacturing, in particular to a three-way angle connector and an assembled nine-fold profile cabinet. Background Art

[0002] A cabinet is a freestanding or self-supporting enclosure used to house electrical or electronic equipment. It typically features doors, removable or fixed side panels, and a back panel. Cabinets are an indispensable component of electrical equipment and serve as a carrier for electrical control devices. They are typically constructed of cold-rolled steel or alloys. They provide protection for stored equipment against water, dust, and electromagnetic interference. Cabinets are generally categorized as server cabinets, network cabinets, and console cabinets.

[0003] Currently, 100%-off profile cabinets are widely used in industries such as industry, IT, communications, and construction. These cabinet frames are typically welded together using specialized T-joints. However, due to the large volume occupied by these cabinets, storage and transportation are expensive.

[0004] In order to reduce the transportation and storage costs of cabinets, there are also some practical new three-way connectors and derived assembled cabinets, but there are problems such as complex structure, high manufacturing cost, or poor maintainability. Utility Model Content

[0039] The second three-way angle connector 2 includes a third connecting rod 21 and a first plug-in 22 provided at the end of the third connecting rod 21 and matching the first connecting groove. A connecting through hole 23 is formed on the first plug-in 22 at a position matching the second connecting groove 14.

[0040] The three-way fastener 3 is inserted into the connecting through hole 23 after being screwed through the second connecting groove 14 . The inner walls of the second connecting groove 14 and the connecting through hole 23 may be provided with internal threads matching the three-way fastener 3 .

[0041] As attached Figure 1As shown, in the installed three-way angle connector, the second connecting rod 13 is located behind the three-way joint 11, and the first connecting rod 12 is located above the three-way joint 11; the third connecting rod 21 is on the right side of the three-way joint 11, and the hole on the front side of the three-way joint 11 is the second connecting groove 14, in which the three-way fastener 3 is inserted; as shown in the attached figure Figure 2 As shown, the three-way angle connector 2 2 where the third connecting rod 21 is located can be separated from the three-way angle connector 1 after the three-way fastener 3 is pulled out;
