Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a plug-in fireproof busbar. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] In the prior art, the interior of the plug-in fireproof busbar trunking is filled with fireproof cotton, and the top of the busbar trunking is provided with a reserved plug-in plate for plugging. Nowadays, the top of the plug-in plate is provided with a protective flip cover. Since the traditional cover is fixed to the top of the plug-in plate with screws and the structure is relatively simple, the screws need to be removed with tools when using the cover, which is inconvenient. At the same time, the screws are easy to lose after removal. Secondly, when the busbar trunking is assembled with each other, it is inconvenient to align them, which makes it easy for the busbar trunking to shift during assembly. Utility Model Content

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when the reserved plug-in plate is required, the pressing and squeezing block squeezes the connecting spring. The movement of the pressing and squeezing block causes the mounting plate to move. The movement of the mounting plate causes the locking block to move away from the inside of the slot, so that the fixing block is not limited and the flip cover flips, thereby opening the reserved plug-in plate. When the flip cover is on top of the base plate, the sealing rubber block enters the inside of the sealing groove and is locked in the inside of the slot by the locking block, thereby stabilizing the base plate and the flip cover. This eliminates the use of traditional screws and makes the use of the reserved plug-in plate more convenient.

[0015] 2. In this utility model, when assembling the busbar trunking body, the stabilizing plate and the positioning plate are aligned, and the positioning rod enters the interior of the positioning hole, while the limiting plate enters the interior of the positioning groove. The threaded knob is rotated so that the threaded knob enters the interior of the second threaded hole and the first threaded hole at the same time, thereby stabilizing the two sets of busbar trunking bodies and aligning the two sets. This facilitates the alignment when assembling the busbar trunking bodies and reduces the phenomenon of misalignment during assembly. Attached Figure Description
