Description

Technology Field

[0001] The present invention relates to a switchboard, and more specifically, to a switchboard with a structure that improves design freedom and assembly convenience. Background Technology

[0002] A distribution panel is a general term for a device that receives power and distributes it to various electrical loads. A distribution panel receives power by being electrically connected to an external power source. A distribution panel can provide power by being electrically connected to external equipment or any device.

[0003] Switchboards play a key role in various electrical installation systems, and in particular, in addition to power distribution, they can perform functions such as controlling and protecting the electrical system.

[0004] A distribution panel includes components for external electrical connection. For example, a distribution panel may be equipped with busbars. Busbars can be connected to external power sources or loads in various forms to receive and distribute power.

[0005] Meanwhile, as the rated capacity used by electrical devices increases, there is a growing number of cases where multiple busbars are interconnected and utilized. In this case, the busbars provided in each of the multiple distribution panels must be electrically connected.

[0006] In this case, the configuration for connecting each busbar is generally not provided within the distribution panel itself but is provided separately and connected to each busbar individually. Therefore, the above configuration may be subject to constraints depending on the location, size, or shape of the busbar to be connected.

[0007] Specifically, for the transmission of commonly used three-phase current, a separate busbar must also be provided for each phase. In order to ensure insulation performance between the currents flowing through each busbar, each busbar must be spaced apart by a sufficient distance.

[0008] Therefore, the above configuration for connecting each busbar must be formed to have a size smaller than the distance between busbars through which currents of different phases are conducted.

[0009] In addition, if the busbars to be connected have structural differences, there is a concern that the assembly process of the above configuration may become more difficult due to differences in the location where the fastening members are joined.

[0010] Accordingly, a method for easily combining multiple busbars is required.

[0011] Korean Published Patent Document No. 10-2024-0151031 discloses a thermal busbar assembly. Specifically, it discloses a thermal busbar assembly in which a spacer and a clamp unit are arranged between the ends of a plurality of busbars spaced apart at a predetermined interval, thereby enabling the distance between each busbar to be maintained constant.

[0012] However, the thermal busbar assembly disclosed in the aforementioned prior art only discloses a method for easy assembly after assuming that the busbars to be connected are already arranged at predetermined intervals. In other words, the prior art fails to provide a method for easily joining each busbar regardless of the arrangement distance of the busbars.

[0013] Korean Registered Patent Document No. 10-1726367 discloses a method for installing a busbar for connecting a transformer in a distribution panel. Specifically, it discloses a method for installing a busbar for connecting a transformer in a distribution panel that includes a close-contacting spacing member that is coupled to the incoming through-pin of an incoming busbar and the connecting through-pin of a connecting busbar, respectively, thereby enabling easy coupling of the incoming busbar and the connecting busbar.

[0014] However, the method for installing busbars for connecting transformers in a distribution board disclosed in the aforementioned prior art can be applied only when the incoming busbar and the connecting busbar are arranged to partially overlap. The aforementioned prior art fails to provide a method for easily connecting them when each busbar is arranged parallel to each other along its length. Prior art literature

[0062] The first frame (101) and the second frame (102) differ in their detailed structures, but their overall structures are identical. Accordingly, the description of the parts common to the first frame (101) and the second frame (102) below will be collectively referred to as the frame (100).

[0063] Referring to FIGS. 2 through 11, the frame (100) includes a vertical frame (110), a horizontal frame (120), and a support frame (130).

[0064] The vertical frame (110) forms part of the outer shape of the frame (100). In the illustrated embodiment, the vertical frame (110) forms each side in the horizontal direction of the outer shape of the frame (100). The vertical frame (110) extends in the height direction of the frame (100), in the vertical direction in the illustrated embodiment.

[0103] The sub-hole (230) constitutes another part where the main busbar (200) is joined to the fastening member (400). The sub-hole (230) is formed through the interior of the busbar body (210) in the thickness direction, and in the front-rear direction in the illustrated embodiment. A number of fastening members (410) of the fastening member (400) can be joined through the sub-hole (230).

[0104] The sub-hole (230) may be of any shape through which the male fastening member (410) can be joined. In the illustrated embodiment, the sub-hole (230) is formed as a polygonal prism-shaped space having a polygonal cross-section and a thickness in the front-rear direction.

[0105] At this time, the sub-hole (230) may be formed to have a cross-section with a shape different from that of the main hole (220). Accordingly, the operator can easily and accurately identify the main hole (220) and the sub-hole (230).

[0106] Multiple sub-holes (230) may be formed. Multiple sub-holes (230) may be spaced apart from each other and each may be coupled to multiple fastening members (400). In the illustrated embodiment, the sub-holes (230) are provided as a pair spaced apart in the height direction, i.e., the vertical direction, of the busbar body (210).

[0107] At this time, the sub-holes (230) may be provided in multiple pairs. In the illustrated embodiment, two pairs of sub-holes (230) are provided and positioned adjacent to each side end in the longitudinal direction of the busbar body (210), namely the left end and the right end, respectively.

[0108] The sub-hole (230) is located adjacent to the end of the busbar body (210). The sub-hole (230) is located between the end of the busbar body (210) and the main hole (220).

[0109] Meanwhile, the moving hole (320) of the connecting plate (300), which will be described later, may be positioned to overlap both the main hole (220) and the sub hole (230) located adjacent to each other. Additionally, the coupling hole (330) of the connecting plate (300) may be positioned to overlap with either the main hole (220) or the sub hole (230).

[0110] Additionally, the number of fastening members (410) of the fastening member (400) can be combined with one or more of the main hole (220) and sub hole (230) located adjacent to each other.

[0111] Accordingly, the position of the connecting plate (300) is adjusted so that adjacent main busbars (200) can be electrically connected to each other. A detailed explanation of this will be provided later.

[0112] The main hole (220) and sub hole (230) may be spaced apart by a spacing distance (d) along the longitudinal direction of the busbar body (210), and in the illustrated embodiment, the left-right direction. As will be described later, the spacing distance (d) may be less than or equal to the extended length of the moving hole (320).

[0113] Accordingly, the moving hole (320) may be positioned to overlap with one or more of the main hole (220) and the sub hole (230) along the thickness direction of the connecting body (310) and the front-rear direction in the illustrated embodiment.

[0114] Accordingly, it will be understood that the connecting plate (300) coupled to either the first busbar (201) or the second busbar (202) can be moved in the longitudinal direction, i.e., the left-right direction, by the distance (d) between the extension length of the moving hole (320) and the distance (d).

[0115] A connecting plate (300) electrically connects a plurality of main busbars (200) arranged adjacently along its length direction. The connecting plate (300) can be coupled to and electrically connected to each end of the plurality of main busbars (200). Accordingly, a plurality of main busbars (200) arranged adjacently can be electrically connected to each other.

[0116] The connecting plate (300) can be combined with the first busbar (201) and the second busbar (202), respectively. At this time, the connecting plate (300) can be positioned to overlap with a part of the first busbar (201) and a part of the second busbar (202), respectively. In the illustrated embodiment, the connecting plate (300) can be positioned to overlap with the right end of the first busbar (201) and the left end of the second busbar (202), respectively.

[0117] At this time, the connecting plate (300) can be moved along the longitudinal direction of the main busbar (200), in the left-right direction in the illustrated embodiment, while connected to either the first busbar (201) or the second busbar (202). Accordingly, even if the first busbar (201) and the second busbar (202) are not placed in the correct position, the relative positions of the first busbar (201) and the second busbar (202) can be adjusted by the connecting plate (300).

[0118] Accordingly, the first busbar (201) and the second busbar (202) can be easily and accurately combined.

[0119] The connecting plate (300) is connected to the frame (100). Specifically, one part of the connecting plate (300) is directly connected to the vertical frame (110), and another part of the connecting plate (300) can be indirectly connected to the vertical frame (110) by the main busbar (200).

[0120] The connecting plate (300) is coupled to the main busbar (200). The connecting plate (300) is positioned to overlap with the longitudinal end of the main busbar (200) and can be coupled to the main busbar (200) so as to be movable in the longitudinal direction of the main busbar (200).

[0121] The connecting plate (300) is combined with a fastening member (400). The connecting plate (300) can be fixedly connected to the frame (100) or the main busbar (200) by the fastening member (400).

[0122] Multiple connecting plates (300) may be provided. Multiple connecting plates (300) may each be coupled to multiple main busbars (200) to electrically connect them.

[0123] Referring to FIG. 12, the connecting plates (300) are provided in four groups. Each group of connecting plates (300) is connected to a plurality of first busbars (201) and second busbars (202) that are spaced apart in the vertical direction.

[0124] Additionally, as illustrated in FIG. 13, each group may be configured to include six connecting plates (300). The number of groups of connecting plates (300) and the number of connecting plates (300) provided in each group may be changed in correspondence with the number of groups of main busbars (200) and the number of main busbars (200) provided in each group.

[0125] At this time, a plurality of connecting plates (300) and a plurality of main busbars (200) may be alternately arranged along the thickness direction of the busbar body (210), and in the illustrated embodiment, the front-rear direction (Fig. 23). Accordingly, the connection and electrical state of the connecting plates (300) and the main busbars (200) can be stably maintained.

[0126] In the embodiment illustrated in FIGS. 12 to 14, the connecting plate (300) includes a connecting body (310), a moving hole (320), and a coupling hole (330).

[0127] The connecting body (310) constitutes the body of the connecting plate (300). The connecting body (310) is a component of the connecting plate (300) that is in direct contact with and energized by the busbar body (210). The connecting body (310) may be positioned to overlap at least partially with the busbar body (210).

[0128] Another configuration of the connecting plate (300) is formed in the connecting body (310). In the illustrated embodiment, a moving hole (320) and a coupling hole (330) are formed through the interior of the connecting body (310).

[0129] The connecting body (310) is coupled with a fastening member (400). Specifically, the connecting body (310) may be coupled with a fastening member (400) that penetrates a moving hole (320) or a coupling hole (330). At this time, the connecting body (310) may be moved along the longitudinal direction of the busbar body (210), and in the illustrated embodiment, in the left-right direction, with the fastening member (400) penetrating the moving hole (320) as an axis.

[0130] Accordingly, as will be described later, the connecting body (310) may be movably coupled to the main busbar (200), particularly the first busbar (201), by means of a fastening member (400).

[0131] The connecting body (310) may be of any shape such that it is positioned to overlap at least partially with the busbar body (210) to make contact and conduct electricity, and a moving hole (320) and a coupling hole (330) may be formed therein. In the illustrated embodiment, the connecting body (310) is formed in a plate shape having a length in the left-right direction, a height in the up-down direction, and a thickness in the front-back direction.

[0132] In the above embodiment, the height of the connecting body (310) may be less than or equal to the height of the busbar body (210). Additionally, the length of the connecting body (310) may be less than or equal to the length of the busbar body (210).

[0133] A through hole (320) is formed on one side in the longitudinal direction within the interior of the connecting body (310).

[0134] The moving hole (320) is a configuration in which the connecting plate (300) is coupled to either the first busbar (201) or the second busbar (202). At this time, the connecting plate (300) can be movably coupled to either the first busbar (201) or the second busbar (202) by the moving hole (320). In the illustrated embodiment, the connecting plate (300) is movably coupled to the first busbar (201) by the moving hole (320).

[0135] The moving hole (320) provides a space for the connecting plate (300) to move along its length, and in the illustrated embodiment, in the left-right direction. The moving hole (320) is formed through the interior of the connecting body (310). A male fastening member (410) is coupled through the moving hole (320). As the connecting plate (300) moves, the relative position of the male fastening member (410) inside the moving hole (320) can be changed.

[0136] The moving hole (320) may extend in the longitudinal direction of the connecting body (310), in the left-right direction in the illustrated embodiment. At this time, the length in the extension direction of the moving hole (320), in the left-right direction in the illustrated embodiment, may be defined as the separation distance (d). As described above, in one embodiment, the separation distance (d) may be equal to the distance between the main hole (220) and the sub hole (230).

[0137] As described above, the moving hole (320) can be positioned to overlap with one or more of the main hole (220) and the sub hole (230) along the thickness direction of the connecting body (310), that is, the front and rear direction.

[0138] In the above embodiment, when the connecting body (310) is moved to the maximum right after the moving hole (320) is positioned to overlap with the main hole (220) and the male fastening member (410) is connected through it, the moving hole (320) can also be positioned to overlap with the sub hole (230). In this state, additional male fastening members (410) can be connected through the moving hole (320) and the sub hole (230), respectively.

[0139] Additionally, as the connecting body (310) moves while the male fastening member (410) is coupled to the moving hole (320), the position of the coupling hole (330) can be adjusted along the longitudinal direction of the connecting body (310), that is, the left and right direction. Accordingly, the coupling hole (330) can be positioned to easily overlap with the other of the first busbar (201) and the second busbar (202).

[0140] The moving hole (320) may be of any shape that can provide a space through which the male fastening member (410) passes and through which the male fastening member (410) can move relatively. In the illustrated embodiment, the moving hole (320) is formed as a plate-shaped space having a length in the left-right direction and a height in the up-down direction, and a thickness in the front-back direction.

[0141] At this time, each end in the longitudinal direction of the moving hole (320), that is, the left and right directions, may be formed rounded so as to be convex outward. That is, in the above embodiment, the cross-section of the moving hole (320) may be oblong.

[0142] Multiple moving holes (320) may be formed. Multiple moving holes (320) may be spaced apart from each other along the height direction of the connecting body (310). Multiple moving holes (320) may be arranged to overlap each of multiple main holes (220) or multiple sub-holes (230). In the illustrated embodiment, a pair of moving holes (320) are formed and spaced apart in the vertical direction.

[0143] At this time, one end in the longitudinal direction of the moving hole (320), the left end in the illustrated embodiment, may be positioned to overlap with the main hole (220) of the first busbar (201). Additionally, the other end in the longitudinal direction of the moving hole (320), the right end in the illustrated embodiment, may be positioned to overlap with the sub hole (230) of the first busbar (201).

[0144] The coupling hole (330) is configured such that the connecting plate (300) is coupled to the other of the first busbar (201) and the second busbar (202). At this time, the connecting plate (300) can be fixedly coupled to the other of the first busbar (201) and the second busbar (202) by the coupling hole (330). In the illustrated embodiment, the connecting plate (300) is fixedly coupled to the second busbar (202) by the coupling hole (330).

[0145] The coupling hole (330) is configured such that the connecting plate (300) is coupled with another fastening member (400). A fastening member (400) that couples the connecting plate (300) with the other one of the first busbar (201) and the second busbar (202), specifically the second busbar (202) in the illustrated embodiment, may be coupled to the coupling hole (330).

[0146] At this time, the connecting body (310) can be fixedly coupled to the second busbar (202) by a male fastening member (410) that penetrates the coupling hole (330). Accordingly, as will be described later, it will be understood that after the male fastening member (410) penetrates the moving hole (320) and the connecting body (310) is movably coupled to the first busbar (201), the connecting body (310) can be moved so that the coupling hole (330) and the main hole (220) or sub hole (230) of the second busbar (202) can be aligned.

[0147] In the illustrated embodiment, the coupling hole (330) may be positioned to overlap with the sub-hole (230) of the second busbar (202). A male fastening member (410) may be coupled through the coupling hole (330).

[0148] The coupling hole (330) is positioned to overlap with the sub-hole (230) and may have any shape through which the male fastening member (410) can pass. In the illustrated embodiment, the coupling hole (330) is formed as a plate-shaped space having a circular cross-section and a thickness in the front-rear direction.

[0149] Multiple coupling holes (330) may be formed. Multiple coupling holes (330) may be spaced apart from each other along the height direction of the connecting body (310). Multiple coupling holes (330) may be arranged to overlap each other with multiple main holes (220) or multiple sub-holes (230). In the illustrated embodiment, a pair of coupling holes (330) are formed and spaced apart in the vertical direction.

[0150] At this time, the coupling hole (330) may be positioned to overlap with the sub-hole (230) positioned closest to the longitudinal end of the second busbar (202).

[0151] The fastening member (400) combines the frame (100), the main busbar (200), and the connecting plate (300). The fastening member (400) may penetrate the main busbar (200) or the connecting plate (300). The fastening member (400) may securely connect the main busbar (200) and the connecting plate (300) to the frame (100). The connection may be achieved by the fastening member (400) penetrating the main hole (220) or the sub hole (230) and the connecting hole (330).

[0152] Additionally, the fastening member (400) can movably connect the main busbar (200) and the connecting plate (300). The connection can be achieved by the fastening member (400) penetrating the main hole (220) or the sub hole (230) and the moving hole (320).

[0153] A plurality of fastening members (400) may be provided. A plurality of fastening members (400) may be combined with one or more of a plurality of main holes (220), sub-holes (230), moving holes (320), and coupling holes (330).

[0154] The fastening member (400) may include any configuration capable of combining the frame (100), the main busbar (200), and the connecting plate (300). In the illustrated embodiment, the fastening member (400) is configured to include a male fastening member (410) and a female fastening member (420).

[0155] The male fastening member (410) penetrates the main hole (220), sub hole (230), moving hole (320), or sub hole (230). The male fastening member (410) is formed to extend in the thickness direction of the busbar body (210) or connecting body (310), in the front-rear direction in the illustrated embodiment. A polygonal head is provided on one side in the longitudinal direction of the male fastening member (410), at the front end in the illustrated embodiment.

[0156] At this time, the head may be formed to have a larger cross-sectional area compared to other parts of the fastening member (410).

[0157] The other end in the longitudinal direction of the male fastening member (410), the rear end in the illustrated embodiment, is exposed to the outside of the busbar body (210) and the connecting body (310) and can be coupled with the female fastening member (420). That is, the male fastening member (410) and the female fastening member (420) can be arranged facing each other with the frame (100), the main busbar (200), or the connecting plate (300) in between.

[0158] The male fastening member (410) and the female fastening member (420) may be provided in any shape capable of connecting the frame (100), the main busbar (200), and the connecting plate (300), respectively. In the illustrated embodiment, the male fastening member (410) is provided as a screw member, and the female fastening member (420) is provided as a nut member. In the above embodiment, screw threads may be formed on the outer circumference of the male fastening member (410) and the inner circumference of the female fastening member (420).

[0159] Referring to FIGS. 15 to 25, the process of combining and energizing a first bus bar (201) and a second bus bar (202) provided in a distribution board (10) according to an embodiment of the present invention by means of a connecting plate (300) is illustrated as an example.

[0160] In the illustrated embodiment, the moving hole (320) of the connecting plate (300) is assumed to be coupled with the main hole (220) of the first busbar (201). Alternatively, the moving hole (320) of the connecting plate (300) may be coupled with the main hole (220) of the second busbar (202). In either case, it is sufficient that the connecting plate (300) can be moved relative to the first busbar (201) or the second busbar (202) to which it is coupled.

[0161] Referring to FIGS. 15 to 17, the process of connecting a connecting plate (300) to a first bus bar (201) connected to a first frame (101) is illustrated as an example.

[0162] As described above, the first busbar (201) and the connecting plate (300) are each provided in multiple numbers and can be spaced apart along the thickness direction, and in the illustrated embodiment, along the front-rear direction.

[0163] At this time, a plurality of connecting plates (300) can each be inserted into a space formed where a plurality of first busbars (201) are spaced apart from each other. That is, the first busbars (201) and connecting plates (300) can be arranged alternately along the front-rear direction.

[0164] At this time, the moving hole (320) of the connecting plate (300) may be positioned such that one side in the longitudinal direction, the left end in the illustrated embodiment, overlaps with the main hole (220) of the first bus bar (201). Subsequently, when a male fastening member (410) penetrates the moving hole (320) and the main hole (220) respectively, the connecting plate (300) can be movably coupled to the first bus bar (201).

[0165] In the above state, the connecting plate (300) can be moved in its length direction, to the left or right in the illustrated embodiment, so that it is adjusted to the state illustrated in FIG. 20, i.e., so that the sub-hole (230) of the first bus bar (201) and the coupling hole (330) overlap.

[0166] At this time, as best illustrated in FIG. 17, the sub-hole (230) of the first busbar (201) is in an open state. After the position of the connecting plate (300) is adjusted in the sub-hole (230) of the first busbar (201) and the connection with the second busbar (202) is completed, a connecting member (410) is passed through so that a plurality of first busbars (201) can be connected.

[0167] Referring to FIGS. 18 to 21, the process of connecting the second busbar (202) to the first busbar (201) while the connecting plate (300) is connected is illustrated as an example.

[0168] As described above, a plurality of second busbars (202) are also provided and can be spaced apart in the thickness direction and in the front-rear direction in the illustrated embodiment.

[0169] At this time, a plurality of connecting plates (300) can each be inserted into a space formed where a plurality of second busbars (202) are spaced apart from each other. That is, the second busbars (202) and connecting plates (300) can be arranged alternately along the front-rear direction.

[0170] At this time, the coupling hole (330) of the connecting plate (300) may be positioned to overlap with the sub-hole (230) of the second busbar (202). Subsequently, when the male fastening member (410) penetrates the coupling hole (330) and the sub-hole (230), the second busbar (202) and the connecting plate (300) can be fixedly coupled.

[0171] At this time, as best illustrated in FIG. 20, the main hole (220) of the second busbar (202) is open. After the connection between the second busbar (202) and the connecting plate (300) is completed, a male fastening member (410) can be passed through the main hole (220) of the second busbar (202) to connect multiple second busbars (202).

[0172] Referring to FIGS. 22 to 25, a distribution board (10) in which the first bus bar (201), the second bus bar (202), and the connecting plate (300) are combined is shown as an example.

[0173] In the above state, the connecting plate (300) is positioned so that the coupling hole (330) overlaps with the sub-hole (230) of the second busbar (202) and is coupled to the second busbar (202) by a fastening member (400). Additionally, the connecting plate (300) is positioned so that the moving hole (320) overlaps with the main hole (220) or sub-hole (230) of the first busbar (201) and is coupled to the first busbar (201) by a fastening member (400).

[0174] Subsequently, a fastening member (400) for connecting multiple first busbars (201) is connected through the sub-hole (230) of the first busbar (201), and a fastening member (400) for connecting multiple second busbars (202) is connected through the main hole (220) of the second busbar (202).

[0175] Accordingly, the first busbar (201) and the second busbar (202) are connected to the connecting plate (300) and can be electrically connected to each other.

[0176] In the distribution board (10) according to the embodiment of the present invention described above, the connecting plate (300) is movably coupled to the first busbar (201), so that the relative position with respect to the second busbar (202) can be easily adjusted. Accordingly, compared to the case where the first busbar (201) or the second busbar (202) itself is moved, the difficulty of the work for coupling and energizing the first busbar (201) and the second busbar (202) is reduced, and efficiency can be improved.

[0177] Although embodiments of the present invention have been described, the concept of the present invention is not limited to the embodiments presented in this specification. A person skilled in the art who understands the concept of the present invention may easily propose other embodiments within the scope of the same concept by adding, changing, deleting, or adding components, and such are also to be considered to fall within the scope of the concept of the present invention.
