[0023] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figure 1 , Figure 2 , Figure 4As shown, this embodiment provides a busbar device, including: busbars 1, which can be provided with four, namely, A-phase busbar, B-phase busbar, C-phase busbar and N-phase busbar, and a plurality of electrode connection ears 2 are provided on the busbar 1 along the length direction of the busbar 1; for example, five electrode connection ears 2 can be provided on one side edge of each busbar 1, and of course, the number of electrode connection ears 2 can also be provided on each busbar 1 as required. The housing includes a rear seat body 3 and a front cover body 4 connected to each other; a plurality of first insulating partitions 5 are arranged in the rear seat body 3 along the height direction of the rear seat body 3, and the space between two adjacent first insulating partitions 5 above and below forms a slot body 6 for accommodating the busbar 1; and a plurality of openings 9 for the electrode connection ears 2 to extend out are provided on the front cover body 4. For example, five first insulating partitions 5 can be arranged in the rear seat body 3 to form a four-layer slot body 6, which is used to install the A-phase busbar, the B-phase busbar, the C-phase busbar and the N-phase busbar respectively. The rear seat body 3 and the front cover body 4 may be connected by screws. For example, threaded holes may be provided on both the rear seat body 3 and the front cover body 4, and the two may be connected and fixed by screws.

[0028] The busbar device provided in this embodiment is provided with a shell. When the busbar 1 is installed in the shell, only the electrode connection ears 2 on the busbar 1 are exposed to the outside to improve safety. Moreover, a first insulating partition 5 is provided between two adjacent layers of busbars 1 to increase the creepage distance. There is no need to increase the internal space of the distribution box, which is conducive to miniaturization of the distribution box and reduction of costs.

[0029] Among them, a plurality of second insulating partitions 7 are arranged on the side of the front cover body 4 facing away from the base body, and the plurality of second insulating partitions 7 are arranged at intervals along the length direction of the front cover body 4. After the front cover body 4 is connected to the rear base body 3, the second insulating partitions 7 separate the two adjacent electrode connection ears 2 on the left and right of the busbar 1. For example, the second insulating partitions 7 can be arranged on both sides of each opening 9 on the front cover body 4.

[0030] Among them, the shell is divided into several circuit areas along the length direction of the shell, each circuit area has four different electrode connection ears 2, and the four different electrode connection ears 2 come from different busbars 1. For example, the shell can be divided into two circuit areas along the length direction of the shell, which are respectively recorded as the main circuit area and the branch circuit area. The main circuit area can be used to connect to the main power supply, and the branch circuit area can be used to connect to the branch power supply. For example, the main circuit area can have four electrode connection ears 2, and the four electrode connection ears 2 come from the A-phase busbar, the B-phase busbar, the C-phase busbar and the N-phase busbar, respectively, and the four electrode connection ears 2 form a group. For example, the branch circuit area can have sixteen electrode connection ears 2, and the sixteen electrode connection ears 2 are divided into four groups of four each, and the four electrode connection ears 2 in each group come from the A-phase busbar, the B-phase busbar, the C-phase busbar and the N-phase busbar. Of course, a group of electrode connection ears 2 in the main circuit area can also be used to connect to the branch power supply, and a group of electrode connection ears 2 in the branch circuit area can also be used to connect to the main power supply. That is, the main power supply and the branch power supply can be installed interchangeably on the left and right to meet different market demands.

[0031] The housing adapted to each circuit area is independent, and the housings of two adjacent circuit areas can be spliced ​​and connected to each other. For example, the housings of two adjacent circuit areas can be riveted, clamped, or screwed, etc. This arrangement allows the housing to be modularly assembled, making it easier to flexibly assemble according to usage requirements.

[0032] When the busbar 1 is an integrated structure, each busbar 1 passes through different circuit areas. At this time, the housings of two adjacent circuit areas may contact each other but not be fixed. When the busbar 1 is an integrated structure, the problem of increased contact resistance caused by splicing with transition copper bar screws can be avoided.

[0033] like Figure 4 As shown, the front cover body 4 can be an integrated structure.

[0034] like Figure 5 As shown, the front cover body 4 can be divided into a first cover body 10 and a second cover body 11 which are assembled together along its diagonal line.

[0035] like Figure 3 As shown, a plurality of heat dissipation holes 8 are arranged on the surface of the rear seat body 3 facing the front cover body 4. Such arrangement can improve the air permeability of the shell and improve the heat dissipation effect.

[0036] The entire shell may be made of insulating material to improve insulation performance.

[0037] In summary, the busbar device in the present application has high safety performance, improves the safety of electrician operators operating equipment in the distribution box, and has a small size, which can reduce the space of the distribution box.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
