[0035] Furthermore, if Figure 1 As shown, the upper connecting plate 2 and the main board 1 are integrally formed into an arc shape, and / or the lower connecting plate 3 and the main board 1 are integrally formed into an arc shape. In this embodiment, the upper connecting plate 2 and the main board 1 are integrally formed, and / or the lower connecting plate 3 and the main board 1 are integrally formed, thereby enhancing the connection strength between the main board 1 and the upper connecting plate 3 and the lower connecting plate 3.

[0036] Furthermore, if Figure 1 and Figure 2As shown in the figure, the second end of the upper connecting plate 2 has a first bending portion 21, and the bending direction of the first bending portion 21 is the same as the concave direction of the concave portion 11. In this embodiment, the second end of the upper connecting plate 2 is arc-bent toward the side plate 200 of the switch cabinet 100 connected thereto to form the first bending portion 21, and the end face of the first bending portion 21 abuts against the side plate 200.

[0037] Specifically, as Figure 1 and Figure 3 shown, the side plate 200 includes a connecting convex portion 210. An ear hole for connecting with a lifting device is provided on the connecting convex portion 210, and a lifting hole 22 for connecting with the lifting device is provided on the upper connecting plate 2 opposite to the ear hole.

The end of the lower connecting plate 3 bends towards the side plate 200 to form the second bending portion 31, and the end face of the second bending portion 31 abuts against the side plate 200. Specifically, the parallel cabinet connector abuts against the side plate 200 of the switch cabinet 100 through the first bending portion 21 of the upper connecting plate 2 and the second bending portion 31 on the lower connecting plate 3, improving the connection stability between the parallel cabinet connector and the switch cabinet 100, and also improving the overall structural strength of the upper connecting plate 2 and the lower connecting plate 3.

[0041] Further, as Figure 1 and Figure 2 shown, the concave portion 11 abuts against the side plate 200, and welding holes 112 for welding with the side plate 200 are formed in the concave portion 11. In this embodiment, a plurality of welding holes 112 are formed in the concave portion 11. After the concave portion 11 abuts against the side plate 200, the staff uses a welding machine to weld and fix the concave portion 11 and the side plate 200 along the inner edge of the welding holes 112.

[0042] Further, as Figure 1 and Figure 3As shown, the inner recess 11 is provided with a plurality of connection holes 113 for bolts to pass through, and the plurality of connection holes 113 are arranged one-to-one with the plurality of threaded holes of the bus side extension 300. In this embodiment, a plurality of threaded holes are provided on the end surface of the bus side extension 300 along the circumferential direction, and the inner recess 11 is provided with connection holes 113 corresponding to the plurality of threaded holes one-to-one, and the staff uses bolts to fasten the bus side extension 300 to the inner recess 11. Specifically, when the cabinet connector moves to the designated installation position along the guide rod, the assembly hole groove 111 on the inner recess 11 is aligned with the predetermined installation position of the bus side extension 300, and the plurality of connection holes 113 on the inner recess 11 are also aligned one-to-one with the plurality of threaded holes on the bus side extension 300; then the staff fixes the inner recess 11 to the side plate 200, and uses bolts to fix the inner recess 11 to the bus side extension 300.

[0043] Furthermore, a sealing rubber ring is provided on the end surface of the enclosure 12 facing away from the switch cabinet 100, and the sealing rubber rings on the two opposite enclosures 12 are in contact with each other. In this embodiment, the two cabinet connectors are respectively connected to the side panels 200 of the switch cabinets 100 on both sides, and the two cabinet connectors are clamped between two adjacent switch cabinets 100. The upper connecting plate 2 and the lower connecting plate 3 of the two cabinet connectors are in contact with each other to ensure the sealing of the internal installation space; the enclosure 12, the upper connecting plate 2 and the lower connecting plate 3 of the two cabinet connectors are provided with flexible sealing rubber rings on the opposite surfaces, and the sealing rubber rings can form a good seal at the contact point, thereby greatly improving the sealing of the internal installation space; at the same time, the sealing rubber ring can also buffer the collision and friction between the two opposite cabinet connectors, preventing the two cabinet connectors from being damaged due to rigid contact due to excessive external force during installation.
