[0001] This utility model relates to power distribution systems, and in particular to a plug-in box that can be rotated into position and a busbar trunking for installation thereon. Background Technology

[0002] Existing plug-in boxes are designed for installation without interrupting power to the busbar trunking. The plugs are rotated for installation, and the copper contacts abut against the copper busbars to draw power. However, the opening at the bottom of the busbar trunking will change outwards, and the sides of the trunking will expand, affecting the reliability of the contact between the copper contacts and the copper busbars. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a plug-in box that can be rotated into place and a busbar trunking for installation thereon, and the plug-in protrusion of the design card restricts the deformation of the opening.

The retaining device has a round hole for the plug-in connector to pass through. The retaining device has plug-in protrusions on both sides.

[0005] In this scheme, the connector and the housing are first inserted and then rotated. After the clamp is inserted into place, it is fixed. The connector and the housing rotate relative to the clamp. The busbar trough wall extends into the first notch to support the connector and the housing. The insertion protrusion restricts the deformation of the busbar trough opening.

[0006] Preferably, the connector includes a base, the clip is sleeved on the base, the base is provided with a pressure ring, and the clip is located between the pressure ring and the housing.

[0007] In this design, the pressure ring prevents the card from disengaging from the card connector.

[0008] Preferably, the top surface of the housing is provided with a locking tab.

[0009] In this design, the locking tab swings out from the top surface of the box and abuts against the inner wall of the busbar trough, preventing the plug-in box from detaching from the busbar trough.

[0010] Preferably, the locking piece is disposed at one end of the rotating shaft, the rotating shaft passes through the housing, the other end of the rotating shaft is provided with a torsion plate, and the other end of the rotating shaft is threadedly connected with a tension block, the tension block cooperating with the bottom surface of the housing.

[0011] In this design, tightening the tension block can fix the locking plate and the rotating shaft, while loosening the tension block can drive the rotating shaft to rotate via the torsion plate.

[0012] Preferably, a connecting column is provided below the base, the box body is provided with a connecting hole for the connecting column to pass through, and a retaining ring is provided at the end of the connecting column. Both the connecting hole and the connecting column have a monolithic cross section.

[0013] In this design, the retaining ring prevents the connecting post from disengaging from the connecting hole, and the housing drives the connector through the contact between the wall of the connecting hole and the surface of the connecting post.

[0014] This type of busbar trunking for installation in a plug-in box includes a trunking body and copper busbars. The trunking body has a mounting cavity for the plug to rotate, and the mounting cavity has an opening for the plug to extend into. The trunking body includes an aluminum alloy shell and an insulating bracket. The insulating bracket is fitted inside the aluminum alloy shell and has a mounting groove for the copper busbar to be installed. The bottom surface of the aluminum alloy shell has a plug-in groove corresponding to the plug-in protrusion.

[0015] In this design, the insertion slot is for the insertion protrusion to be inserted.

[0016] Preferably, the top surface of the connector is provided with a second notch for the limiting protrusion to extend into, and the inner wall of the insulating bracket is provided with a limiting protrusion corresponding to the second notch.

[0017] In this design, the limiting protrusion extends into the second notch to ensure proper installation and prevent reverse installation.

[0018] Preferably, the inner wall of the aluminum alloy shell is provided with an assembly protrusion, and the outer wall of the insulating bracket is provided with an assembly groove corresponding to the assembly protrusion.

[0019] In this design, the assembly protrusion matches the assembly slot to prevent assembly errors.
