[0002] The bus duct can carry high currents of hundreds of amperes or even thousands of amperes to meet the electricity needs of industry, commerce, and data centers. The bus duct is equipped with outlets along the way, which can easily connect loads from different locations without the need for separate wiring, thereby improving the power distribution efficiency. In actual bus duct power distribution work, it is necessary to install a junction box on the bus duct. Shrapnel-type plugs are usually used between the junction box and the bus duct for power connection. Thanks to the flexible and convenient shrapnel power connection method, it is widely used.

At the same time, the structure can realize automatic control of suction to prevent staff from forgetting, and can be more suitable for high-voltage circuits to improve circuit quality. At the same time, the structure can use the sealing test piece 7 to detect the sealing of the cavity between the sealing plug-in tube 501 and the plug-in tube 1011, thereby ensuring the negative pressure degassing effect and avoiding the failure of negative pressure degassing caused by leakage.

When leakage occurs, an alarm can be directly given, which further ensures the power connection effect of the present structure. When the power connection slider 301 is close to the busbar connecting plate 101 for docking, the sliding shaft 602 will squeeze the busbar connecting plate 101. At this time, the sliding shaft 602 drives the piston 603 to retract, and negative pressure will be generated in the piston hole 3013 to suck the cavity between the sealing plug sleeve 501 and the plug-in sleeve 1011, that is, the conductive paste is defoamed by negative pressure to improve the conductive effect. When there is leakage in the cavity between the sealing plug sleeve 501 and the plug-in sleeve 1011, the piston 603 can drive the negative pressure spring 703 under the pull of the negative pressure tension spring 706, and approach the negative pressure power connection column 704, and the sealing warning light 705 can be powered on and light up to alarm.

When the power-connecting box needs to be disassembled, assembled, maintained, etc., when the busbar copper busbar 103 is in the energized state, the electromagnet 203 will also electromagnetically absorb the locking slider 201 to block the busbar copper busbar 103, and the staff cannot operate the power-connecting spring piece 402 to insert into the busbar copper busbar 103, and the power-connecting spring piece 402 can be blocked by the locking slider 201 When the busbar copper bar 103 is powered off, the electromagnet 203 is also powered off and no longer magnetically attracts the locking slider 201. Under the pull of the locking tension spring 202, the locking slider 201 can be retracted and no longer blocks the busbar copper bar 103. The corresponding staff can directly hold the power-connecting slider 301 to drive the power-connecting spring 402 to insert into the busbar copper bar 103 for power connection. After the busbar copper bar 103 is connected to the power-connecting spring 402, the busbar copper bar 103 is powered on. When the power-connecting spring 402 is connected, the electromagnet 203 will also electromagnetically attract the locking slider 201. At this time, the locking slider 20 1 will pass through the sealing insert 501 and the power-connecting spring piece 402 for limit locking. When the power-connecting spring piece 402 needs to be docked, the power-connecting slider 301 is inserted into the four guide shafts 102. At this time, the threaded pressing sleeve 303 is rotated to squeeze the power-connecting slider 301 to move, so that the power-connecting spring piece 402 can be inserted into the busbar copper bar 103. At this time, tightening the threaded pressing sleeve 303 can squeeze the power-connecting slider 301 to fit closely with the busbar connecting plate 101 for installation; when the staff docks the power-connecting spring piece 402, the power-connecting slider 301 moves inward, which can drive the sealing insert 501 to be inserted into the plug-in sleeve 1011 is sealed, and the plug film 503 is also inserted into the busbar copper bar 103. Conductive paste can be applied to the inner side of the connecting spring piece 402 in advance. When the connecting spring piece 402 is attached to the busbar copper bar 103, if the busbar copper bar 103 or the connecting spring piece 402 is deformed or rusted, causing the connecting spring piece 402 to move outward too much, the virtual connecting spring piece 403 on the connecting spring piece 402 will touch the connecting piece 502. The virtual connecting spring piece 403 and the connecting piece 502 on the outer side of each connecting spring piece 402 are respectively connected in series with the prompt light 304 on the same side. At this time, the prompt light 304 can be powered on and light up for prompting;When the connecting slider 301 is close to the busbar connecting plate 101 for docking, the sliding shaft 602 will squeeze the busbar connecting plate 101. At this time, the sliding shaft 602 drives the piston 603 to retract, and negative pressure will be generated in the piston hole 3013. The connecting groove 3012 is connected to the pressure extraction hole 3011, and the cavity between the sealing plug-in cylinder 501 and the plug-in cylinder 1011 can be sucked through the pressure extraction hole 3011, that is, the conductive paste is defoamed by negative pressure to improve the conductive effect. At the same time, when the piston 603 retracts, negative pressure is generated. When the negative pressure is on, the sealing test cylinder 701 will also generate negative pressure. Under the action of negative pressure, the sliding column 702 can move toward the piston 603, stretching the negative pressure tension spring 706. On the contrary, when there is leakage in the cavity between the sealing insert 501 and the plug-in cylinder 1011, the negative pressure generated in the piston hole 3013 will gradually disappear. Under the pull of the negative pressure tension spring 706, the piston 603 can drive the negative pressure spring 703 to approach the negative pressure connection column 704 and fit it. At this time, the sealing indicator light 705 can be powered on and light up to indicate. ;
