[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0030] like Figures 1-7As shown, a cabinet bus assembly of this utility model includes a base plate 1, with an assembly shell 2 mounted on the top surface of the base plate 1. The bus assembly also includes a plastic busbar 4, which is installed inside the assembly shell 2, and copper busbars 5, which are fitted onto both sides of the plastic busbar 4. Both the plastic busbar 4 and the copper busbar 5 have multiple through holes, which are arranged vertically in a corresponding row, and the through holes of the plastic busbar 4 and the copper busbar 5 are aligned to form a channel. Multiple fasteners 3 are inserted into the channel, passing through the copper busbar 5 and the plastic busbar 4 to securely connect them. The fasteners 3 include a first component 31 and a second component 32 connected together. The first component 31 passes through the corresponding channel of the plastic busbar 4 and the two copper busbars 5, and the second component 32 can be staggered and fitted onto the side of the plastic busbar 4, abutting against the copper busbar 5.
[0031] The first component 31 and the second component 32 of the fastener 3 are both provided with a bolt hole, into which a long bolt 33 is inserted. The long bolt 33 passes through an opening on one side of the assembly housing 2 and also passes through an opening on the other side of the assembly housing 2. A locking cap 34 is threadedly connected to one end of the bolt through the opening. The locking cap 34 is threadedly locked to the bolt hole of the long bolt 33, and the end of the locking cap 34 is in contact with the side wall of the assembly housing 2.
[0032] The plastic busbar 4 has grooves on both sides. The two copper busbars 5 are respectively inserted into the grooves on both sides and fit tightly against the plastic busbar 4, while being electrically isolated from each other. In the direction perpendicular to the copper busbars, some of the fasteners 3 are inserted into the channel between the copper busbar 5 and the plastic busbar 2 from the left, and the other part of the fasteners 3 are inserted into the channel between the copper busbar 5 and the plastic busbar 2 from the right. They are fixedly connected to the assembly shell 2 by long bolts 33 and locking caps 34. That is, the fasteners 3 have a fixing function. The fasteners 3 are made of insulating material. In other words, the fasteners 3 penetrate through the copper busbar 5 and the plastic busbar 4 to fix and connect the copper busbar 5 and the plastic busbar 4.
[0033] The fastener 3 includes a first component 31 and a second component 32. The width of the first component 31 is greater than the width of the second component 32, and also greater than the width of the through hole of the copper busbar 5. In other words, the cross-sectional area of the first component 31 is greater than the cross-sectional area of the second component 32 and greater than the through hole area of the copper busbar 5. The longitudinal section of the fastener 3 can be roughly T-shaped. Furthermore, the second component 32 is inserted into one side of the corresponding channel, while the first component 31 is located on the outer side of the copper busbar 5 on the same side. Parts of the first components 31 of multiple fasteners 3 are located on the outer side of one of the two copper busbars 5, and other parts of the first components 31 of multiple fasteners 3 are located on the outer side of the other two copper busbars 5. Preferably, two adjacent fasteners 3 are inserted into the channel from different sides, one on the left and one on the right, meaning that the fasteners 3 can be staggered and attached to the copper busbars 5 on both sides of the plastic busbar 4. One end face of the first part 31 abuts against the surface of the copper busbar 5, providing the copper busbar 5 with the pressing force against the middle plastic busbar 4, which can stably press the copper busbar 5 located on both sides of the plastic busbar 4 onto the plastic busbar 4, ensuring the stability of the entire busbar. In addition, the arrangement of the fasteners 3, which are alternately inserted into the plastic busbar 4 and the copper busbar 5, can provide support for the copper busbar 5.
[0034] The assembly shell 2 includes a stiffener 21 and a shell 22. The shell 22 has a back plate 222 and two side plates 223 extending forward from both sides of the back plate 222, thus presenting a U-shape on the horizontal plane. The two side plates 223 of the shell 22 are located outside the plastic busbar 4 and the copper busbar 5. The end face of the first component 31 of the fastener 3 is located on the inner side of one of the two side plates 223 of the shell 22, while the end face of the second component 32 of the fastener 3 is located on the inner side of the other side plate 223 of the shell 22. Two stiffeners 12 are installed inside the side wall of the housing 22. The stiffeners 21 can be used to enhance the rigidity of the assembly housing 11 and improve its stability. In addition, the housing 22 and the stiffeners 21 can be made of conductive material to provide a ground potential for the system. The two side plates 223 of the housing 22 have multiple through holes that are aligned with the channels of the plastic busbar 4 and the copper busbar 5. The long bolts 33 are inserted into the through holes from the outside of one side plate 223 of the housing 22 and locked to the locking caps 34 located outside the through holes of the other side plate 223 to fix the plastic busbar 4 and the two copper busbars 5 to the housing 22, thus completing the assembly of the assembly housing 2.
[0035] See Figure 6 The housing 2 is equipped with a bending portion 221, which is located on the inner side of the lower end of the housing 2 and extends forward from the bottom end of the back plate 222. One end 41 of the plastic busbar 4 contacts the bending portion 221. The copper busbar 5 does not contact the bending portion 221. The bending portion 221 forms a support at the bottom, providing support for the entire copper busbar 5 and the plastic busbar 4, increasing the stability of the entire bus. That is, the bottom end of the plastic busbar 4 is lower than the bottom ends of the two copper busbars 5. When the housing 2 is mounted on the base plate 1, the outer surface of the bending portion 221 is connected to the base plate 1. The bending portion 221 has heat dissipation holes to increase the overall heat dissipation efficiency.
