Description

Technical Field

[0001] The utility model relates to the technical field of busbar adapters, and particularly relates to a plug-in busbar adapter connecting row. Background Art

[0002] The busbar system is a power distribution device for efficiently transmitting current, and is especially suitable for the economic and reasonable wiring requirements of high-rise buildings and large-scale factories. Since the busbar is produced in sections during the production process, it is necessary to connect each section of the busbar into a whole through a busbar connecting row during actual installation; when transmitting electric energy by using the busbar, it is necessary to use multiple busbar connecting rows to connect multiple busbars to form a wire trough with a suitable length.

[0003] After retrieval, the publication (announcement) number: CN209730755U discloses a plug-in epoxy-coated busbar adapter connecting row, which includes an insulating shell, a plug row arranged in the insulating shell, and a backing plate installed on one side surface in the insulating shell. There is more than one plug row, and they are arranged side by side. The plug row includes two fitting side plates with concave inner side surfaces, plugging pieces arranged at both ends of the side plates and fixed to the side plates, and a hot melt pipe arranged in the side plates; by arranging a plurality of plug rows side by side in the insulating shell and adapting to the insulating shell, it is compact and reasonable, convenient to replace, can quickly troubleshoot during a fault, enable the power supply line to quickly run again, and avoid causing large-area and long-time power outages. In addition, the plug row fixes the plugging pieces by the side plates and uses a hot melt pipe to connect the plugging pieces, which has a simple structure, reduces the weight of the plug row, improves the electrical conductivity, and improves the practicability and safety of the connecting row.

[0004] Although the above solution reduces the weight of the plug row, improves the electrical conductivity, and improves the practicability and safety of the connecting row, when connecting busbars with different heights, the connecting row is difficult to adapt, and the connecting row is difficult to clamp busbars with different widths, resulting in poor applicability.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0013] Preferably, the widths of the plurality of deformation blocks and the circular grooves in the connecting unit decrease sequentially from top to bottom, and the deformation blocks are clamped with the corresponding circular grooves.

[0014] Preferably, the extrusion assembly in the limiting unit includes a second elastic column arranged inside the groove, a second spring arranged on the surface of the second elastic column, and an extrusion plate fixedly connected to one end of the second elastic column.

[0015] Preferably, the two extrusion plates on one side in the limiting unit are arranged in parallel.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

After the busbar is placed, if the height of the busbar is greater than the height of the partition plate, it will drive the distance between the two limiting plates to increase, and at the same time, the first elastic column and the first spring will stretch, so that the fixing column and the socket column extend out, and at the same time, the two extension plates will extend out from the rectangular holes, and then the adaptive adjustment is carried out according to the height of the busbar, improving the applicability of the connecting row.

[0018] Second, in the present utility model, through the setting of the limiting unit, the width of the busbar trunking is observed, the partition plate is clamped with two appropriate vertical slots, and after the busbar trunking is placed, under the action of the second elastic column and the second spring, the two pressing plates are driven to press different heights of the busbar trunking, so that while optimizing the clamping effect, the busbar trunking with different widths can be clamped.

[0035] The length of the fixing column 209 in the connecting unit 2 is the same as the length of the socket column 210, and the fixing column 209 extends into the socket column 210.
