The length direction of the wall is consistent.

Fig. 2 is a schematic cross-sectional view of the bus duct. With reference to Fig. 2, in this embodiment, the insulating bracket 130 has a receiving slot 131 extending along its own length, and the notch for accommodating the slot 131 is located in the insertion slot 111. There is a protrusion 132 at the notch of part of the accommodating through groove 131, and the protrusion 132 is close to the notch of the insertion groove 111. The conductive plate 120 is located in the accommodating through groove 131, and the conductive plate 120 has a part exposed in the insertion groove 111. The first power-connecting surface 121 , the first power-connecting surface 121 does not protrude from the opening of the accommodating through groove 131 .

Fig. 3 is a schematic structural diagram of the plug connector 20. With reference to Fig. 3, in this embodiment, the plug connector 20 includes an insulating plate 210 and a conductive part 220, the conductive part 220 is located on one side of the insulating plate 210, and the conductive part 220 has a The power connection part 221 of the protrusion 132 of the board 210, the power connection part 221 has a second power connection surface 222, which is plugged into the plug connector 20 in the insertion slot 111, and can go over the protrusion 132, so that the first power connection surface 121 and the The second power-connecting surface 222 is in electrical contact.

Figure 4 is a schematic diagram of the plug connection between the bus duct 10 and the plug joint 20, in combination with Figure 4, in this embodiment, there are multiple plug slots on the housing for accommodating the insulating bracket and the conductive plate, and for the insulation The brackets provide the mounting base. The insulating bracket has a receiving slot 131, the conductive plate is plugged into the receiving slot 131, and the first power-connecting surface is exposed in the slot, thereby realizing the insulating installation between the conductive plate and the housing, ensuring Ensure electricity safety.

During the process of inserting the plug connector into the socket slot, the second power-connecting surface of a part of the power-connecting part will directly pass over the notch of the accommodating through-slot 131 without the protrusion 132, and firstly connect with the accommodating through-slot 131 The first electrical surface of the conductive plate is in contact with each other to realize the electrical connection between the conductive part and the conductive plate. At the same time, the second power-connecting surface of another part of the power-connecting part will be pushed up by the protrusion 132 and cannot contact the first power-connecting surface of the conductive plate accommodated in the through groove 131 (see the upper part of FIG. 4 ). As the plug joint continues to move into the socket slot, the second power-connecting surface of the power-connecting part pushed up by the protrusion 132 will cross the protrusion 132 and connect with the first power-connecting surface of the conductive plate accommodated in the through groove 131. The surface contact realizes the electrical connection between the conductive part and the conductive plate (see the lower part of Fig. 4).

That is to say, by having a protrusion 132 at the notch of a part of the accommodating through groove 131, there is no protrusion 132 at the notch of another part of the accommodating through groove 131, so that a part of the conductive part is first connected to the corresponding conductive plate Electrically connected, the conductive part of the other part moves with the continuous insertion of the plug connector, and then electrically connects with the conductive plate. In this way, the conductive plate that is electrically connected first is set as the ground conductive plate, so that the plug connector can be grounded first, which further improves the safety of electricity use.

Moreover, since the surface contact between the conductive plate 120 and the power connection part 221 is realized through the first power connection surface 121 and the second power connection surface 222 , the insertion stability between the bus duct 10 and the plug connector 20 can be improved.

In one application, one side of the bus duct 10 is the insertion side, and the opening of the insertion slot 111 is located on the insertion side.
