Abstract

A connector for combining cabinets includes a flexible connector which is deformable and is configured to communicate inner cavities of a first cabinet machine and a second cabinet machine. The flexible connector includes a hollow cavity for an electrical connector to pass through, and the hollow cavity forms a first open end and a second open end at two ends of the flexible connector. The first open end is sealingly connected to a side plate of the first cabinet machine, the second open end is sealingly connected to a side plate of the second cabinet machine, and the first cabinet machine and the second cabinet machine are two adjacent cabinet machines. The structure of the connector for combining cabinets is simple and the mounting is convenient, and the flexible connector can automatically adapt to the mounting position through its own deformation so as to meet the normal mounting requirements.

First claim

The invention claimed is:

1. A connector for combining cabinets, comprising a flexible connector which is deformable and is configured to communicate inner cavities of a first electrical cabinet and a second electrical cabinet, wherein the flexible connector comprises a hollow cavity for an electrical connector to pass through, and the hollow cavity forms a first open end and a second open end at two ends of the flexible connector, the first open end is sealingly connected to a side plate of the first electrical cabinet, the second open end is sealingly connected to a side plate of the second electrical cabinet, and the first electrical cabinet and the second electrical cabinet are two adjacent cabinet electrical cabinets;
wherein the side plate of the first electrical cabinet comprises a first embedding groove recessed toward the inner cavity of the first electrical cabinet, the side plate of the second electrical cabinet comprises a second embedding groove recessed toward the inner cavity of the second electrical cabinet, the first open end of the flexible connector is configured to be embedded in the first embedding groove and fixedly connected with the first embedding groove, and the second open end of the flexible connector is configured to be embedded in the second embedding groove and fixedly connected with the second embedding groove.

2. The connector for combining cabinets according to claim 1 , further comprising a first pressing ring which matches an inner cavity of the first open end, wherein the first pressing ring is embedded in the inner cavity of the first open end, and the first pressing ring and the flexible connector are mounted in the first embedding groove through a first fastening screw.

3. The connector for combining cabinets according to claim 2 , further comprising a second pressing ring which matches an inner cavity of the second open end, wherein the second pressing ring is embedded in the inner cavity of the second open end, and the second pressing ring and the flexible connector are mounted in the second embedding groove through a second fastening screw.

4. The connector for combining cabinets according to claim 3 , wherein the first open end is provided with a first floating mounting plate, a central portion of the first floating mounting plate is provided with a first mounting sleeve arranged outside the first open end, and the first pressing ring, the flexible connector and the first floating mounting plate are fixedly connected through a third fastening screw, an edge of the first floating mounting plate is provided with a first flange which abuts against a bottom edge of the first embedding groove, and the first flange is mounted in the first embedding groove through the first fastening screw; and/or
the second open end is provided with a second floating mounting plate, a central portion of the second floating mounting plate is provided with a second mounting sleeve arranged outside the second open end, the second pressing ring, the flexible connector and the second floating mounting plate are fixedly connected through a fourth fastening screw, an edge of the second floating mounting plate is provided with a second flange which abuts against a bottom edge of the second embedding groove, and the second flange is mounted in the second embedding groove through the second fastening screw.

5. The connector for combining cabinets according to claim 1 , further comprising a first mounting plate and a second mounting plate, wherein the first mounting plate is configured to sealingly mount on the side plate of the first electrical cabinet, and a first protruding opening extendable into the inner cavity of the first electrical cabinet is provided on the first mounting plate, and the first protruding opening constitutes the first embedding groove;
the second mounting plate is configured to sealingly mount on the side plate of the second electrical cabinet, and a second protruding opening extendable into the inner cavity of the second electrical cabinet is provided on the second mounting plate, and the second protruding opening constitutes the second embedding groove.

6. The connector for combining cabinets according to claim 5 , wherein a sealing strip is provided between the first mounting plate and the side plate of the first electrical cabinet, and between the second mounting plate and the side plate of the second electrical cabinet.

7. The connector for combining cabinets according to claim 1 , wherein both the first open end and the second open end are rectangular.

8. The connector for combining cabinets according to claim 7 , wherein a cross-sectional area of the first open end is unequal to a cross-sectional area of the second open end, and the flexible connector is in a shape of a quadrangular frustum pyramid.

9. The connector for combining cabinets according to claim 7 , wherein a cross-sectional area of the first open end is equal to a cross-sectional area of the second open end, and the flexible connector is in a shape of a cuboid.

10. The connector for combining cabinets according to claim 1 , wherein the flexible connector is a silicone rubber connector or a silicon-titanium canvas connector.

11. A power distribution cabinet assembly, comprising at least a first electrical cabinet and a second electrical cabinet adjacent to each other, wherein the first electrical cabinet and the second electrical cabinet are electrically connected through the connector for combining cabinets according to claim 1 .
