Description

Technical Field

[0001] The utility model relates to the technical field of wiring devices, in particular to a wiring device for a transformer conductive rod. Background Art

[0002] The incoming and outgoing wires of the distribution transformer are both made of aluminum core insulated wire. When the wires are connected to the transformer, the wire heads are often made into rings and directly put on the transformer conductive rods. The wires are then pressed onto the lower nut with gaskets and then tightened with fastening nuts.

[0003] An existing wiring device for transformer conductive rods (publication number: CN215896141U) has at least the following disadvantages:

[0004] When the above patent is in use, after the annular wire head is sleeved on the outside of the conductive ring and the top of the wiring ring, the two fixed rings can be rotated to squeeze the wire, and then the connecting block is squeezed to drive the limit rod and the limit ring to penetrate the front fixed block, so that the wire is initially fixed by the fixed ring. After the rotating ring is driven to rotate by the rotating rod, the squeezing ring will be driven downward to squeeze the wire and fix the wire again. The method of fixing the wire in the above patent is too cumbersome and requires multiple fixing operations, which is not convenient for installers to use. Utility Model Content
