Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinets, and more specifically, to a power distribution cabinet with stable grounding and high safety. Background Art

[0002] The power distribution cabinet is an important device used to install, protect and manage electrical equipment. It is usually installed in the power distribution room or distribution room of buildings, factories or other places. Electrical equipment is installed inside the power distribution cabinet to control and distribute electricity. In order to protect the safety of personnel and equipment, the power distribution cabinet needs to be safely grounded through the grounding wire.

[0003] The existing power distribution cabinet only uses one wire to connect the cabinet door and the cabinet body, so that the cabinet door is connected to the cabinet body through the wire to achieve the grounding of the cabinet door. However, the wire is usually exposed to the outside and is not adequately protected. When maintenance personnel open the cabinet door for maintenance, they may sometimes touch the wire, causing the wire to be damaged or broken, resulting in failure of the grounding wire. The cabinet door cannot be effectively grounded, increasing the risk of electric shock for maintenance personnel and users, thereby causing safety hazards. In addition, only one wire is used to connect the cabinet door and the cabinet body, resulting in the cabinet door grounding relying on this one wire. If the wire is damaged or broken, the cabinet door cannot be grounded, and the cabinet door is energized, causing safety hazards. Utility Model Content

[0009] Furthermore, the first pressing plate has a first waist-shaped hole matching the first stud, and the second pressing plate has a second waist-shaped hole matching the second stud.

[0010] Thus, the first stud can pass through the first pressing plate, and the second stud can pass through the second pressing plate.

[0011] Furthermore, a side of the first mounting groove close to the second mounting block is open, and a side of the second mounting groove close to the first mounting block is open.

[0012] Furthermore, one end of the first through groove away from the flexible connecting piece is open, and one end of the second through groove away from the flexible connecting piece is open.

[0013] This makes it easier to install the shielding protection unit.

[0014] Further, the two first studs are located on the same vertical line, and the two second studs are located on the same vertical line.

[0015] This makes the installation of the wires more convenient.

[0016] Furthermore, the shielding protection unit is made of rubber material.

[0017] This can provide a buffer in the event of an accidental collision, thereby protecting the safety of the wires.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. In the power distribution cabinet of the present application, two wires are connected between the cabinet door and the cabinet body, making the grounding more reliable and reducing the potential safety hazards caused by wire damage or breakage. Even if one wire is damaged, the other wire can still ensure the grounding of the cabinet door, avoiding the safety risks caused by the cabinet door being electrified, thus providing high safety.

[0020] 2. In the power distribution cabinet of the present application, the shielding protection unit shields the two wires, so that maintenance personnel will not touch the wires during maintenance, effectively reducing the possibility of damage to the wires, and maintenance personnel can more easily perform inspection and maintenance work on the power distribution cabinet without having to worry about touching the wires and causing safety problems.
