[0002] The busbar is an indispensable component for power distribution and supply installation in a switch cabinet. For the installation requirements of the busbar and copper bar, it is necessary to select appropriate fixing devices and connection methods to ensure the reliable fastening of the connection between structures. In the existing switch cabinet equipment, for the installation of the busbar and copper bar, standardized installation parts are usually used, and holes need to be drilled at the overlapping positions. The setting positions are relatively inflexible. When there are multiple copper bars and multiple installation positions, the positioning and installation operations will be extremely cumbersome and difficult. Moreover, in a switch cabinet with a compact space, the small space further increases the difficulty of installation operations, and multiple connections cannot be set reasonably and effectively.

[0025] A special-shaped horizontal bus structure for switch cabinets is applied to the power connection of multiple devices in a switch cabinet, and includes a bus 1, a bus clamp 42, a bracket 41, a quick connector 5, a T-shaped bolt 2, and a connection row 3.

[0026] The bus 1 has a straight bar-shaped structure and is arranged horizontally in the switch cabinet. Refer to Figure 2 and Figure 4 , a chute 11 is opened on the bus 1 along its straight direction. The two ends of the chute 11 in the straight direction communicate with the two ends of the bus 1 to form openings, and the chute 11 also communicates with the side wall of the bus 1 to form a strip-shaped opening, so that the projection cross-section of the chute 11 in the straight direction along the bus 1 is T-shaped.

[0027] Refer to Figure 5 and Figure 3, the head of the T-bolt 2 is of a square structure, forming a T-shaped structure with the whole body of the bolt, so that it can match the T-shaped cross-section of the chute 11, and the head of the T-bolt 2 can enter the chute 11 from either end of the two openings at both ends of the chute 11. After the T-bolt 2 enters the chute 11, the inner walls of the chute 11 are respectively abutted against the positions of the head of the T-bolt 2, forming a constraint on the T-bolt 2, making the T-bolt 2 perpendicular to the busbar 1. The T-bolt 2 can slide relative to the chute 11 in a straight line direction in this posture, so as to realize setting it at any position in the straight line direction of the busbar 1.

[0028] A first mounting hole 31 is provided at the end of the lap joint row 3. After the T-bolt 2 is set on the busbar 1, the first mounting hole 31 at the end of the lap joint row 3 is passed through the T-bolt 2, and a nut is screwed in to press the lap joint row 3 against the busbar 1, so as to realize the quick installation between the lap joint row 3 and the busbar 1.

[0029] Preferably, four chutes 11 are provided on one busbar 1 in this embodiment. The four chutes 11 are arranged in two groups respectively on the opposite side walls of the busbar 1. The two chutes 11 on the same side are arranged parallel to each other. Four first mounting holes 31 distributed in a rectangular array are provided at the end of the lap joint row 3. The lap joint row 3 is fixed to the busbar 1 through four T-bolts 2, effectively enhancing the connection strength and stability.

[0030] Heat dissipation holes 12 are also provided through the busbar 1. The heat dissipation holes 12 can be arranged in multiple directions on the busbar 1 to improve the heat dissipation capacity of the busbar 1.

[0031] In some embodiments, multiple busbars 1 can be arranged in a row. When multiple busbars 1 are arranged in series in a straight line direction in the switchgear, the connection between adjacent busbars 1 is realized by setting a quick connector 5. A slot is provided in the quick connector 5, and the slot penetrates through the quick connector 5 to form two open ends. The two adjacent busbars 1 are respectively inserted into the quick connector 5 through the two open ends of the slot to form a connection. A plurality of second mounting holes 51 are provided on the quick connector 5. The second mounting holes 51 communicate with the slot, and the positions of the second mounting holes 51 are opposite to the chutes 11. Before setting the connection of the busbar 1, the T-bolt 2 is first passed through the second mounting hole 51 from the inside of the slot to the outside. During the process of inserting the busbar 1 into the slot, the head of the T-bolt 2 is synchronously inserted into the chute 11, and then a nut is screwed onto the T-bolt 2 to press the busbar 1 against the quick connector 5, realizing the fixed connection and installation between the busbar 1 and the quick connector 5.

[0032] In some embodiments, multiple busbars 1 can be arranged in a column. Refer to Figure 1 and Figure 2 , through the busbar clamp 42 and the bracket 41, multiple busbars 1 are arranged side by side in parallel with each other in the switchgear in turn. The busbar clamp 42 is of a C-shaped structure. Refer to Figure 7, a first clamping groove 421 for clamping on the outer periphery of the bus bar 1 is formed on the inner side of its C shape, and a second clamping groove 422 for clamping on the outer periphery of the bracket 41 is formed on the outer side of its C shape. The bracket 41 is in a straight bar structure. Refer to Figure 6 , the bracket 41 is arranged horizontally and perpendicular to the row of bus bars 1. The bus bar clips 42 on multiple bus bars 1 can be simultaneously clamped on the same bracket 41. A plurality of columnar protrusions 423 are arranged in the second clamping groove 422, and through holes 411 for the columnar protrusions 423 to pass through are arranged on the bracket 41. When the bracket 41 is clamped with the second clamping groove 422, through the penetration cooperation between the columnar protrusions 423 and the bracket 41, a stop fixation between the bracket 41 and the bus bar clip 42 is formed.

[0033] The bracket 41 is fixedly arranged in the switch cabinet. Two parallel upper and lower brackets 41 are set as a group of brackets 41. The bus bar 1 is arranged between the two brackets 41. Bus bar clips 42 are respectively arranged on the upper and lower sides of the bus bar 1 for clamping with the two brackets 41 respectively, so as to form a support for the bus bar 1. A plurality of groups of brackets 41 can be set and are arranged in sequence along the straight line direction of the bus bar 1 to ensure the fixed position of the row of bus bars 1.

[0034] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
