Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to an inlet and outlet sealing structure of a power distribution cabinet. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] When the current power distribution cabinet is in use, the external transmission line needs to pass through the side through-hole of the cabinet to enter the interior. During the threading operation, a rubber sleeve structure is sleeved on the through-hole position to form a sealing effect. A single rubber sleeve connection makes the sealing effect poor, and when the transmission line is pulled, it will still move, causing the connector to be pulled out. Utility Model Content
