[0002] With the rapid popularization and iterative update of AI technology, the global AI wave has begun to surge, and more and more data centers have begun to transform into AI intelligent computing centers. The demand for electric energy of AI intelligent computing centers far exceeds that of general data centers. There are already high-current products of 1000A or more for rail buses dedicated to data centers, but there are few breakthroughs in plug-in boxes that can adapt to them. In order to adapt to the power distribution needs of large-load cabinets, high-current plug-in boxes are imperative.

[0003] In the prior art, the patent name is universal tap box, and the patent number is CN111386585B. The tap box includes a latch that automatically secures the tap box to the busway when the mast is inserted into the busway. The latch is in the form of a single spring-loaded member that locks onto the rail when the mast top is pushed into the busway. A button-actuated cam member pushes the latch off the rail to allow the mast top to be withdrawn from the busway. The button and cam member are independent of the mechanism that extends and retracts the contacts when the mast top is inserted into and locked to the busway. The tap box can also include a non-contact current monitoring sensor with a voltage-sensing insert that can assist circuit breakers in switching in applications other than the tap box, and can also include an infrared emission panel that can monitor various circuit breakers from outside the tap box.

[0004] However, the existing single-contact bus plug-in box only has one plug-in plate, and in order to facilitate installation and ensure stable connection, the thickness of the plug-in plate and the contact for connecting the bus are correspondingly thin, which greatly reduces the current that the single-contact bus plug-in box can withstand.
