Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment cabinet technology, and relates to an assembly connector device and an assembly cabinet. Background Technology

[0002] Server racks are an indispensable component of electrical equipment, serving as the carrier for electrical control devices. They are generally made of cold-rolled steel sheet or alloys. They provide protection against water, dust, and electromagnetic interference for the stored equipment, including server racks, network racks, and control console racks.

[0003] Among them, the sheet metal structure cabinet assembly structure uses sheet metal bending as connection points. The sheet metal structure has a uniform thickness, making it impossible to strengthen the structure according to the stress distribution. In addition, the locking and fixing are mostly in the front and back direction. To ensure strength, multiple fixing points are set, which leads to complicated installation. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide an assembly connector device and an assembly cabinet for a sheet metal bending and welding frame structure.

[0005] Technical solution: The present invention provides an assembly connector device, comprising an assembly main connector, an assembly secondary connector, and fastening bolts; the assembly main connector has a front-rear locking mating surface and a lateral locking mating surface, the front-rear locking mating surface and the lateral locking mating surface forming a 90° angle in space, and threaded holes adapted to the fastening bolts are provided on both the front-rear locking mating surface and the lateral locking mating surface; The assembly sub-connector includes a first connecting part and a second connecting part. The first surface of the first connecting part is in close contact with the front-rear locking mating surface. The first connecting part is provided with a threaded hole that mates with the threaded hole on the front-rear locking mating surface. The second surface of the second connecting part is in close contact with the lateral locking mating surface. The second connecting part is provided with a threaded hole that mates with the threaded hole on the lateral locking mating surface.

[0006] This technical solution allows the axes of the two sets of fastening bolts to form a 90° angle in space, locking in from the side and front and back respectively. This can restrict the multi-directional degrees of freedom of the lateral depth support, and through spatial orthogonal locking, it can reduce the use of fastening bolts while improving structural strength.

[0007] Furthermore, a tapered positioning protrusion is provided on the front and rear locking mating surfaces to reinforce the lateral locking mating surfaces. The function of the tapered positioning protrusion is to avoid the horizontal depth support rotational degree of freedom after fixing. Through the synergistic effect of the above-mentioned spatial orthogonal locking and the tapered positioning protrusion, additional reinforcement is provided in the horizontal weak direction during the cabinet vibration test.

[0008] Furthermore, a boss is provided on the front and rear locking mating surface. The boss serves to position the first connecting part of the assembled sub-connector, ensuring accurate alignment during assembly. Furthermore, the main and secondary connecting parts are made of die-cast cast iron.

[0009] Another technical solution of this utility model provides an assembly cabinet, including a front frame, a rear frame, several depth support beams, and the above-mentioned assembly connector device. The assembly sub-connectors are welded to the two ends of the depth support beams, and the assembly main connectors are welded to the four corners of the front frame and the rear frame. The front frame, the rear frame, and the several depth support beams are connected by fastening bolts to form a cabinet.

[0010] Furthermore, the assembly sub-connector also includes a positioning part for positioning the depth support beam, the positioning part being engaged in the groove of the depth support beam.

[0011] Beneficial effects: Compared with the prior art, the present invention has the following advantages: 1. The assembly and connecting device of the present invention includes a front-to-back locking mating surface and a side locking mating surface forming a 90° angle in space, as well as a matching corresponding connecting part, so that two sets of fastening bolts can be locked in from the side and front-to-back respectively, which can restrict the multi-directional degrees of freedom of the side depth support. Through spatial orthogonal locking, the use of fastening bolts is reduced while the structural strength is improved, which can meet the use requirements of the cabinet structure in earthquake and high vibration environment.

[0012] 2. The cabinet of this utility model adopts the above-mentioned assembly connector device at the connection point, so that the frame can be divided into two types (frame body and depth support beam). When transporting in large quantities, it occupies less space than welding a whole frame, thereby reducing transportation costs. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, an assembly connector device 100 includes an assembly main connector 1, an assembly secondary connector 2, and fastening bolts 3. The assembly main connector 1 includes a front-to-back locking mating surface 11 and a lateral locking mating surface 12. The front-to-back locking mating surface 11 and the lateral locking mating surface 12 form a 90° angle in space. The front-to-back locking mating surface 11 has a threaded hole 71 that is adapted to the fastening bolts 3, and the lateral locking mating surface 12 has a threaded hole 72 that is adapted to the fastening bolts 3.

[0022] The assembly sub-connector 2 includes a first connecting portion 21 and a second connecting portion 22. The first surface of the first connecting portion 21 is in close contact with the front-rear locking mating surface 11, and a threaded hole 81 matching the front-rear locking mating surface 11 is provided on the first connecting portion 21. The second surface of the second connecting portion 22 is in close contact with the lateral locking mating surface 12, and a threaded hole 82 matching the lateral locking mating surface 12 is provided on the second connecting portion 22. One fastening bolt passes through the threaded holes 71 and 81 to lock the first connecting portion 21 onto the front-rear locking mating surface 11, and another fastening bolt passes through the threaded holes 72 and 82 to lock the second connecting portion 22 onto the lateral locking mating surface 12, thereby achieving spatial orthogonal locking between the assembly main connecting portion 1 and the assembly sub-connector 2. Preferably, the assembly sub-connector 2 also includes a positioning portion 23 for positioning the mating parts.

[0023] In one specific embodiment, a tapered positioning protrusion 13 is provided on the front-to-back locking mating surface 11. The function of the tapered positioning protrusion 13 is to avoid the horizontal depth support rotational degree of freedom after fixing. Through the synergistic effect of the above-mentioned spatial orthogonal locking and the tapered positioning protrusion, the horizontal weak direction in the cabinet vibration test is additionally reinforced.

[0024] In one specific embodiment, a boss 14 is provided on the front and rear locking mating surface 11. The boss 14 serves to position the first connecting part 21 of the assembly sub-connector 2, ensuring the alignment accuracy during assembly.

[0025] In one specific implementation, the main connecting component 1 and the secondary connecting component 2 are die-cast from cast iron, which has high hardness and strength.

[0026] During assembly, the main connecting component 1 and the secondary connecting component 2 are fitted together, aligning the front-to-back locking mating surface 11 with the first connecting part 21, the lateral locking mating surface 12, and the second connecting part 22. The fastening bolts 3 then pass through the threaded holes and are tightened. This technical solution creates a 90° angle between the axes of the two sets of fastening bolts in space, allowing them to be locked in from the side and front-to-back directions respectively. This restricts the multi-directional degrees of freedom of the lateral depth support, and through spatial orthogonal locking, reduces the use of fastening bolts while increasing structural strength.

[0027] like Figure 5-7 As shown, this embodiment is an assembled cabinet, including a front frame 4, a rear frame 5, and four depth support beams 6. Assembling sub-connectors 2 are welded to both ends of the depth support beams 6, and assembly main connectors 1 are welded to the four corners of the front frame 4 and the rear frame 5. The front frame 4, rear frame 5, and several depth support beams 6 are connected by fastening bolts 3 to form the cabinet. The assembly connector device 100 is a concealed design within the assembled cabinet, ensuring a consistent appearance. Preferably, the assembly sub-connector 2 is also provided with a square positioning part 23, which can be engaged within the grooves of the depth support beams 6.
