[0016] 1. In technical solution 1, in actual application, the through hole and the first embedded groove are slightly larger than the main body. When adjacent cabinets need to be connected, the main body of the connector is inserted through the through hole of one cabinet into the first embedded groove of another cabinet until the second abutting surface abuts against the bottom of the first embedded groove. At the same time, the main body has a movement margin in the through hole and the first embedded groove. The connector can move in the through hole along a direction perpendicular to the first direction until the first plug-in portion and the second plug-in portion are plugged in, and the flange abuts against the first abutting surface.

It can be seen that, by adopting the technical solution, after the positions of the two cabinets are adjusted, the connecting piece is passed through the through-hole from the inner side of one cabinet and then inserted into the first embedding groove of the other cabinet, and then the connecting piece and the two cabinets are detachably fixed. The whole installation process can be completed inside one cabinet, and there is no need to adjust the position of the cabinet during the installation of the connecting piece. The installation is convenient. In addition, the present invention enables the connecting piece to be plugged into the cabinet where the through-hole is located in a direction perpendicular to the first direction, thereby preventing the connecting piece from moving along the first direction, thereby further facilitating the installation of the first fastener and the second fastener, making the installation simpler.

[0017] 2. In the second technical solution, the first seal and the second seal are provided so that both ends of the connector are sealed, thereby achieving a high level of protection after the two adjacent cabinets are connected.

[0018] 3. In technical solution three, the positioning portion and the first plug-in portion are arranged along the second direction, and the first plug-in portion and the second plug-in portion are plugged in along the second direction, which is easy to install, and the two ends of the flange along the second direction are fixedly connected to the cabinet, and the structure is more stable after the connecting part is installed.

[0019] 4. In technical solution four, the setting of the second embedded groove makes the processing technology of the two side panels of the cabinet basically consistent, thereby reducing the production cost. At the same time, it is easy to form the first abutment surface. The first abutment surface is formed on the bottom wall of the second embedded groove, which is not easy to deform when the side panel of the cabinet is hit, thereby avoiding the sealing effect of the second seal from being affected.

In this way, the two ends of the connector are respectively detachably fixed to two adjacent cabinets, and the first fastener and the second fastener are both located inside the cabinet. The structure of the connector is stable and not prone to shaking, which may affect the sealing effect and the electrical connector, and the first fastener and the second fastener are not easily damaged.

[0022] 7. In technical solution seven, the present invention also provides an electrical cabinet assembly, and each cabinet is connected by the cabinet connection assembly in technical solution two. After the positions of the two cabinets are adjusted, the connecting piece is inserted from the inner side of one cabinet through the through hole into the first embedding groove of the other cabinet in sequence, and then the connecting piece and the two cabinets are detachably fixed.

The positioning part is close to the door body to facilitate the installation of the second fastener.

[0024] 9. In technical solution nine, since the copper busbar assembly often includes a positive copper busbar and a negative copper busbar, the setting of the two through-holes separates the positive copper busbar and the negative copper busbar, which is convenient for wiring; the setting of the two partitions can prevent the first embedded groove from being deformed, thereby preventing the sealing effect of the first seal from being affected when the first embedded groove is deformed; the setting of the second embedded groove makes the processing technology of the two side panels of the cabinet basically consistent, thereby reducing the production cost, and it is easy to form the first abutment surface at the same time, and the first abutment surface is formed on the bottom wall of the second embedded groove compared to the first abutment surface directly formed on the inner wall of the cabinet, which is not easy to deform when the side panel of the cabinet is impacted, thereby avoiding the sealing effect of the second seal from being affected.

The connecting member 20 is moved along the second direction until the positioning protrusion is inserted into the corresponding positioning hole 141, and the second sealing member 50 is sandwiched between the flange 22 and the first abutting surface 122. The first fastener 30 is passed through the first threaded hole 112 and the second threaded hole 2113 to make the body 21 and the corresponding side plate 101 of the cabinet 10 ( Figure 1 The second fastener 31 is threaded through the fourth threaded hole 222 of the flange 22 and the third threaded hole 152 on the positioning portion 15 so that the flange 22 and the corresponding side plate 101 ( Figure 1 The installation is complete by screwing it (on the right side of the center).

[0055] It can be seen that, by adopting the technical solution in this embodiment, after the positions of the two cabinets 10 are adjusted, the connecting piece 20 is inserted from the inner side of one cabinet 10 through the through hole 121 and then inserted into the first embedding groove 11 of the other cabinet 10, and then the two ends of the connecting piece 20 are screwed to the two cabinets 10. The structure of the connecting piece 20 is stable and not easy to shake, and the sealing effect and the electrical connector are not easily affected; the first fastener 30 and the second fastener 31 are both located inside the cabinet 10 and are not easy to be damaged; the entire installation process can be completed inside one cabinet 10, so that there is no need to adjust the cabinet 10 during the installation of the connecting piece 20. The cabinet 10 is positioned so as to facilitate installation. In addition, the present invention enables the second plug-in portion 221 of the connector 20 to be plugged with the first plug-in portion 14 along the second direction, thereby preventing the connector 20 from moving along the first direction, thereby further facilitating the installation of the first fastener 30 and the second fastener 31, making the installation simpler. The positioning portion 15 and the first plug-in portion 14 are arranged along the second direction, and the flange 22 abuts against the third abutting surface 151 of the positioning portion 15, which facilitates the fastening of the positioning portion 15 and the flange 22, and makes the two ends of the flange 22 along the second direction fixedly connected to the cabinet 10, and the installation structure of the connector 20 is more stable. The setting of the second embedding groove 12 makes the processing technology of the two side panels 101 of the cabinet 10 basically consistent, thereby reducing the production cost. At the same time, it is easy to form the first abutting surface 122. The first abutting surface 122 is formed on the bottom wall of the second embedding groove 12. Compared with the first abutting surface 122 directly formed on the inner wall of the cabinet 10, the first abutting surface 122 is not easy to be deformed when the side panel 101 of the cabinet 10 is impacted, thereby avoiding the sealing effect of the second sealing member 50 from being affected. In addition, the setting of the second embedding groove 12 also prevents the second fastener 31 of the screw flange 22 and the positioning portion 15 from protruding out of the cabinet 10, and is less likely to be damaged.
