Description

Technical Field

[0001] This invention demonstrates a composite busbar, belonging to the field of busbar technology. Background Technology

[0002] Busbars are conductive metal materials widely used in power distribution systems, primarily for transmitting electricity from the power source to various loads. They are mainly made of copper and aluminum, with brass as a secondary material, and feature high conductivity and corrosion resistance. Common forms include flat bars, rectangular bars, and tubular bars. Tin plating can enhance oxidation resistance, and electroplating can increase contact resistance.

[0003] In existing distribution boxes, the busbar routing method needs to be set according to the installation location of each circuit breaker. Busbars usually have multiple conductors, all of which need to be fixed to the box. Therefore, the busbar routing requires a lot of space, which will encroach on the installation space of the circuit breakers and affect the number of circuit breakers that can be installed. In addition, the busbars use breakpoint connections at the bends in the routing to allow the busbars to be laid out according to the installation location of the circuit breakers. However, this installation method is not only cumbersome, but the breakpoints of the busbars also pose certain safety hazards. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the installation of busbars occupies a large amount of installation space. To this end, a composite busbar is provided, which can reduce the installation space occupied by the busbar.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A composite busbar includes a housing and a plurality of conductive busbars fixed inside the housing. The housing includes an input section and an output section. Each conductive busbar includes a conductor body and an input connector and an output connector located at both ends of the conductor body. The input connector extends out of the input section, and the output connector extends out of the output section. The housing has a front side and a rear side facing away from each other. The housing is fixed to a wall or a box via the rear side. All conductive busbars are arranged at intervals in the front-rear direction of the housing and are independent of each other.

[0007] The beneficial effects of using the present invention are:

[0008] In this invention, the conductive busbars are laid out in the front-to-back direction of the housing and fixed inside the housing. The rear side of the housing is fixed to the enclosure or wall. After the composite busbar is installed, the projections of all the conductive busbars on the enclosure or wall are basically overlapping. The area occupied by the entire composite busbar on the enclosure or wall is only slightly larger than the area of ​​a single conductive busbar. Compared with the traditional method of arranging multiple conductive sheets separately, the composite busbar occupies a smaller installation area, freeing up more installation space on the enclosure or wall, thereby accommodating more circuit breakers and helping to increase the density of component placement. In addition, the conductors of all the conductive busbars... The overall structure of the main body remains consistent, facilitating mass production of the busbars and effectively reducing production costs. Furthermore, the conductor body is an integral structure with seamless joints at bends, mitigating electrical safety risks such as poor contact at breakpoints, overheating, and discharge, thus significantly improving the operational stability of the busbars. Secondly, the busbars and housing are integrated components; simply mounting the rear side to the enclosure or wall completes the positioning and installation of all busbars, eliminating the need for individual installation and reducing manual assembly steps, thereby minimizing the possibility of assembly errors.

[0009] Preferably, the housing has several mounting channels for accommodating busbars. These channels are arranged along the front-to-back direction of the housing, with partitions between adjacent channels. Each channel accommodates one busbar. Using this design, the partitions physically isolate the mounting channels, allowing each busbar to be placed in its own independent channel. The partitions form an insulating barrier, effectively eliminating the risk of phase-to-phase short circuits caused by busbar displacement or deformation, thus making the use of the busbars safer and more reliable.

[0010] Preferably, the housing includes two first housings and several second housings. Each first housing has a first receiving groove on one side, and each second housing has a second receiving groove on both sides. The second housings are spliced ​​together, and the two second receiving grooves between two adjacent second housings combine to form the installation channel. All second housings are located between two first housings. After the first and second housings are spliced ​​together, the first and second receiving grooves combine to form the installation channel. Using the aforementioned technical solution, the housing is assembled from the first housings on both sides and several second housings in the middle. By increasing or decreasing the number of second housings, the number of installation channels can be increased or decreased simultaneously, corresponding to the configuration of conductor busbars with different circuit numbers. This allows the composite busbar to be used with circuit breakers of different circuit specifications, improving the versatility of the composite busbar. Furthermore, the housing can be disassembled into multiple parts, facilitating stacking, storage, and transportation, thus reducing storage and transportation costs.

[0011] Preferably, the housing also includes a connecting part, with the input and output parts detachably connected to both ends of the connecting part, and the input and output parts located on both sides of the connecting part. Using the aforementioned technical solution, the housing is divided into three main components: the connecting part, the input part, and the output part. The input and output ends are detachable, eliminating the need to disassemble the entire composite busbar during maintenance; only the input or output part needs to be disassembled and reassembled, significantly reducing maintenance time, minimizing downtime, and improving the maintenance efficiency of the composite busbar. Furthermore, the input and output parts are independent detachable components, allowing for the replacement of input and output parts with different wiring specifications according to on-site power distribution requirements, thus adapting to various wiring specifications and providing greater versatility.

[0012] Preferably, the connecting part is elongated, with a first side and a second side on its two sides. The input part is mounted at the lower end of the first side, with its opening at the upper end and the input terminal extending out of the opening. The output part is mounted at the upper end of the second side, with its opening at the lower end and the output terminal extending out of the opening. Alternatively, the input part is mounted at the upper end of the first side, with its opening at the lower end and the input terminal extending out of the opening; the output part is mounted at the lower end of the second side, with its opening at the upper end and the output terminal extending out of the opening.

[0013] Preferably, a first accommodating area for installing an input circuit breaker is formed between the opening of the input section and the first side surface. After the input circuit breaker is electrically connected to the input terminal, the side wall of the input circuit breaker is parallel to the first side surface. Similarly, a second accommodating area for installing an output circuit breaker is formed between the opening of the output section and the second side surface. After the output circuit breaker is electrically connected to the output terminal, the side wall of the output circuit breaker is parallel to the second side surface. Using the aforementioned technical solution, the side wall of the input circuit breaker is placed parallel and close to the first side surface of the connecting section, making the layout of the input circuit breaker and the connecting section more compact, improving the effective utilization of the box or wall area, and making the overall layout more regular and orderly. Furthermore, when the distribution box vibrates during operation, the first side surface can also provide support for the input circuit breaker, preventing the circuit breaker from shifting position. The wiring bolts and conductive contact surfaces between the input circuit breaker and the input terminal are under stable stress and are less prone to loosening during long-term operation. The side wall of the output circuit breaker is placed parallel and close to the second side surface of the connecting section, making the layout of the output circuit breaker and the connecting section more compact, improving the effective utilization of the box or wall area, and making the overall layout more regular and orderly.

[0014] Preferably, the housing has at least two output sections, which are arranged sequentially in a direction away from the connecting section, and adjacent output sections are detachably connected.

[0015] Preferably, the output sections are provided with buckles and slots on opposite sides, and adjacent output sections are detachably connected by buckles and slots.

[0016] Preferably, the conductive busbar is provided with at least two output terminals, each output terminal including a first terminal and a second terminal. The first terminals of all conductive busbars are combined to form an output terminal, and the second terminals of all conductive busbars are combined to form an output terminal. Each output terminal corresponds to an output section.

[0017] Preferably, the input terminals of all conductive busbars are in the same plane, and the plane containing the input terminals is parallel to the rear side of the housing; the output terminals of all conductive busbars are in the same plane, and the plane containing the output terminals is parallel to the rear side of the housing.

[0026] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0027] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] like Figures 1 to 5 As shown, this embodiment illustrates a composite busbar, including a housing 1 and multiple conductive busbars 2 fixed within the housing 1. The housing 1 includes an input section 102 and an output section 103. Each conductive busbar 2 includes a conductor body 21 and input connectors and output connectors located at both ends of the conductor body 21. The input connectors extend out of the input section 102, and the output connectors extend out of the output section 103. The housing 1 has a front side and a rear side facing away from each other. The housing 1 is fixed to a wall or box via the rear side. All conductive busbars 2 are arranged at intervals in the front-rear direction of the housing 1 and are independent of each other.

[0030] In this embodiment, the conductive busbar 2 is laid in the front-rear direction of the housing 1. The conductive busbar 2 is fixed inside the housing 1, and the rear side of the housing 1 is fixed to the box or wall. After the composite busbar is installed, the projections of all conductive busbars 2 on the box or wall are basically overlapping. The area occupied by the entire composite busbar on the box or wall is only slightly larger than the area of ​​one conductive busbar 2. Compared with the traditional scattered installation of multiple conductive sheets, the composite busbar occupies a smaller installation area, which can free up more installation space on the box or wall, thereby accommodating more circuit breakers and helping to improve the arrangement density of components; in addition, the main body of the conductors of all conductive busbars 22 The overall structure of 21 is consistent, which facilitates the mass production of conductive busbars 22 and can effectively reduce the production cost of conductive busbars 22. Furthermore, the main body of the conductor 21 is an integral structure with splicing interfaces without breaks at the bends, which can fundamentally avoid electrical safety risks such as poor contact at break points, easy overheating, and discharge, thereby effectively improving the operational stability of conductive busbars 22. Secondly, conductive busbars 2 and housing 1 are integrated components. Only the rear side needs to be installed as a whole on the box or wall to complete the positioning and installation of all conductive busbars 2. There is no need to lay them out one by one, reducing a lot of manual assembly steps and reducing the possibility of assembly errors during installation.

[0031] Specifically, in this embodiment, the housing 1 is provided with a plurality of installation channels 13 for accommodating the conductive busbars 2. The installation channels 13 are arranged along the front-back direction of the housing 1, and a partition 14 is provided between two adjacent installation channels 13. Each installation channel 13 can accommodate one conductive busbar 2. The partition 14 can physically isolate each installation channel 13, and each conductive busbar 2 is placed in an independent installation channel 13. The partition 14 forms an insulating barrier, which can effectively eliminate the risk of phase-to-phase short circuit caused by displacement or deformation of the conductive busbar 2, making the use of the conductive busbar 2 safer and more reliable.

[0032] Specifically, in this embodiment, the housing 1 includes two first housings 11 and several second housings 12. A first receiving groove is provided on one side of each first housing 11, and second receiving grooves are provided on both sides of each second housing 12. The second housings 12 are spliced ​​together, and the two second receiving grooves between two adjacent second housings 12 combine to form the installation channel 13. All second housings 12 are located between two first housings 11. After the first housings 11 and second housings 12 are spliced ​​together, the first receiving groove and the second receiving groove combine to form the installation channel 13. The housing 1 is assembled from the first housings 11 on both sides and several second housings 12 in the middle. By increasing or decreasing the number of second housings 12, the number of installation channels 13 can be increased or decreased simultaneously, corresponding to the configuration of conductor busbars 2 with different circuit numbers. This allows the composite busbar to be applicable to circuit breakers of different circuit specifications, helping to improve the versatility of the composite busbar. Furthermore, the housing 1 can be disassembled into multiple parts, facilitating stacking, storage, and transportation, thus reducing storage and transportation costs.

[0033] Specifically, in this embodiment, the connecting portion 101 is elongated, while the input portion 102 and output portion 103 are rectangular structures. The two sides of the connecting portion 101 are a first side surface 1011 and a second side surface 1021, respectively. One side of the input portion 102 is attached to and connected to the first side surface 1011 of the connecting portion 101. One end of the conductive bus 22 passes through the first side surface 1011 and extends into the input portion 102. One side of the output portion 103 is connected to the second side surface 1021 of the connecting portion 101. The conductive busbar 22 is attached to each other and remains connected. One end of the conductive busbar 22 passes through the second side 1021 and extends into the output part 103. The input part 102 is spliced ​​to the bottom end of the first side 1011, and the opening of the input part 102 is located at the upper end of the input part 102 and faces upward. The output part 103 is connected to the top end of the second side 1021, and the opening of the output part 103 is located at the lower end of the output part 103 and faces downward. The input part 102, the connecting part 101 and the output part 103 are in a Z-shape.

[0034] It is understandable that in other embodiments, one side of the output section 103 may be spliced ​​to the top of the first side 1011, the opening of the input section 102 is located at the lower end of the input section 102 and faces downward, the output section 103 is connected to the bottom end of the second side 1021, and the opening of the output section 103 is located at the upper end of the output section 103 and faces upward.

[0035] Specifically, in this embodiment, a first receiving area 104 for mounting an input circuit breaker 3 is formed between the opening of the input section 102 and the first side surface 1011. After the input circuit breaker 3 is electrically connected to the input terminal 22, the side wall of the input circuit breaker 3 is parallel to the first side surface 1011. A second receiving area 105 for mounting an output circuit breaker 4 is formed between the opening of the output section 103 and the second side surface 1021. After the output circuit breaker 4 is electrically connected to the output terminal 23, the side wall of the output circuit breaker 4 is parallel to the second side surface 1021. The side 1021 is parallel; the side wall of the input circuit breaker 3 is placed parallel and close to the first side 1011 of the connection part 101, making the layout of the input circuit breaker 3 and the connection part 101 more compact, improving the effective use of the box or wall area, and making the overall layout more regular and orderly; in addition, when the distribution box vibrates during operation, the first side 1011 can also support the input circuit breaker 3, making it less likely for the position of the circuit breaker to shift, and the wiring bolts and conductive contact surfaces between the input circuit breaker 3 and the input terminal 22 are under stable force and are not easy to loosen during long-term operation.

[0036] Specifically, in this embodiment, the housing 1 is provided with at least two output sections 103. The output sections 103 are arranged sequentially along the direction away from the connecting section 101. The two opposite sides of the output sections 103 are provided with buckles 15 and slots 16 respectively. Adjacent output sections 103 are detachably connected by buckles 15 and slots 16.

[0037] Specifically, in this embodiment, the composite busbar includes four conductive busbars 22. Each conductive busbar 22 has an input terminal 22 and several output terminals 23. The input terminals 22 of all conductive busbars 22 are located in the same plane and form an input end. The plane where the input terminals 22 are located is parallel to the rear side of the housing 1. The input end extends out of the opening of the input section 102 and is used to connect to the input circuit breaker 3. The output terminals 23 of the conductive busbars 22 include a first terminal 231, a second terminal 232, and a third terminal 233. All the first terminals 231, 232, and 233 are connected to the input circuit breaker 3. Terminals 231 are combined to form a first output terminal, all second terminals 232 are combined to form a second output terminal, and all third terminals 233 are combined to form a third output terminal. Each output terminal corresponds to an output section 103, and the output terminal is used to connect to the output circuit breaker 4. In addition, all first terminals 231 are in the same plane, and the plane in which the first terminals 231 are located is parallel to the rear side of the housing 1. All second terminals 232 are in the same plane, and the plane in which the second terminals 232 are located is parallel to the rear side of the housing 1. All third terminals 233 are not coplanar.

[0038] It is understandable that all input terminals 22 can be non-coplanar; similarly, all first terminals 231 can also be non-coplanar; and all second terminals 232 can also be non-coplanar.
