Technical Field

[0001] The utility model relates to the technical field related to connection terminals, in particular to a PDU external input terminal structure. Background Art

[0002] A PDU, or power distribution unit, is a power connection device used to distribute power to various devices. Existing PDUs typically connect wires directly through the housing and then connect to internal terminals. This connection method works well for thinner wires, but it can be difficult to bend and route thicker wires used for high-voltage power, as well as difficult to arrange within the power supply.

The wiring unit is characterized in that the wiring unit includes a live wire unit and a neutral wire unit. The live wire unit is provided with a copper busbar assembly. The copper busbar assembly includes a first input copper busbar connected to a conductor and an output copper busbar connected to the first input copper busbar. A fuse terminal is connected between the first input copper busbar and the output copper busbar. The end of the output copper busbar remote from the fuse terminal is connected to the live wire port of the socket module. The neutral wire unit is provided with a second input copper busbar connected to the conductor. The end of the second input copper busbar remote from the conductor is connected to the neutral wire port of the socket module. The cross-sectional areas of the first input copper busbar, the output copper busbar, and the second input copper busbar all meet the rated current of the PDU. A shortcoming of this utility model is that the wiring unit of the device is placed inside the PDU body. Wiring requires penetrating the housing to connect, which makes the wiring process inconvenient. Utility Model Content

After the wire is connected to the conductive post, the direction of the wire can be changed by rotating the screw groove. By changing the direction of the wire, several wires can be arranged in an orderly manner for easy organization. This design facilitates wire arrangement.

[0012] Preferably, the screw cap is provided with a plurality of friction posts distributed in a circumference, and the friction posts are mounted on the screw cap. Since the screw cap needs to drive the wire to rotate together, the friction posts are mounted on the screw cap to increase friction, thereby facilitating the rotation of the screw cap. This design facilitates the rotation of the screw cap.

[0013] The beneficial effects of the utility model are: wiring is completed directly outside the shell, the wires can be connected, the sealing can be improved, the conductive column can be further protected, the wiring is convenient, and the screw cap can be turned and screwed.
