Description

Technical Field

[0001] The present invention relates to a copper bar support member and a distribution board incorporating this copper bar support member.

Background Art

[0002] Conventionally, two different systems may be provided inside a single distribution board. In the example shown in FIG. 5, in distribution board C, a first system including main breaker MB1 and branch breaker group BB1, and a second system including main breaker MB2 and branch breaker group BB2 are provided.

[0003] The branch breaker groups BB1, BB2 belonging to different systems each have a separate bus bar, and copper bar support members 91, 92 are used to support these bus bars. As the copper bar support members 91, 92, for example, the holding member for the main bar described in Patent Document 1 is used.

Patent Document 1

[0005] However, when using the holding member for the main bar described in Patent Document 1, since the holding members for the main bars are arranged separately for each of the bus bars of different systems, in addition to having to secure a wide space between the branch breaker groups BB1, BB2, there is a problem that the number of parts increases.

Problems to be Solved by the Invention

[0006] An object of the present invention is to solve the above-described conventional problems, and to provide a copper bar support member capable of saving space and reducing the number of parts, and a distribution board using the same.

Means for Solving the Problems

[0007] To solve the above problems, the copper bar support member is provided, which has copper bar end insertion parts formed back-to-back on both opposing sides of the main body, surrounded by walls on the top, bottom, left, and right, and partition wall parts separating these insertion parts.

[0008] Furthermore, the distribution board incorporates the copper bar support member and has branch rows for different systems, wherein each branch row has a busbar to which a branch breaker is connected, and a busbar belonging to one system is inserted into the insertion part on one side of the copper bar support member, and a busbar belonging to the other system is inserted into the insertion part on the other side of the copper bar support member.

[0009] Furthermore, it is preferable that the busbars are configured such that their longitudinal ends are inserted into the insertion portions. [Effects of the Invention]

[0010] The present invention makes it possible to provide a copper bar support member that can save space and reduce the number of parts, and a distribution board using the same. [Brief explanation of the drawing]

[Figure 3] This is a cross-sectional view showing how the copper bar support member of the embodiment supports two different busbar systems. [Figure 4] This is a front view showing the distribution board of the embodiment. [Figure 5] This is a front view of a conventional distribution board. [Modes for carrying out the invention]

[0012] The following describes embodiments for carrying out the invention. The copper bar support member 1 of this embodiment comprises a main body 11 formed in a substantially rectangular prism shape extending in the vertical direction as shown in Figure 1, and a fixing part 12 which is a base that is substantially perpendicular to the main body 11 and is fixed to the distribution board by screws or the like. The main body 11 has a first surface 111 and a second surface 112 opposite to the first surface 111. The copper bar support member 1 is made of an insulating resin material.

[0013] As shown in Figures 1 and 3, an insertion portion 13 is formed on the first surface 111 side of the main body 11 into which a linear, plate-shaped copper bar 2 can be inserted. The insertion portion 13 in this embodiment includes an opening 131 that opens to the first surface 111 with a size that allows the longitudinal end of the copper bar 2 to be inserted, a back wall 132 formed at a position opposite the opening 131, and side walls 133 that extend from the top, bottom, left, and right ends of the back wall 132 to the opening 131. In this embodiment, three insertion portions 13 are provided on the first surface 111 side, and three copper bars 2 can be supported on the first surface 111 side in a stacked state with gaps in between.

[0014] In the example shown in Figure 1, the insertion portion 13 is provided with a restricting portion 134 that restricts the vertical movement of the inserted copper bar 2. In this example, the restricting portion 134 is provided in a convex shape extending inward from the left and right ends of the upper side wall 133, but the shape of the restricting portion 134 is not limited to this.

[0015] As shown in Figures 2 and 3, an insertion section 14 is formed on the second surface 112 side of the main body 11. Similar to the insertion section 13, the insertion section 14 includes an opening 141 that opens to the second surface 112 in a size that allows the longitudinal end of the copper bar 2 to be inserted, a back wall 142 formed opposite the opening 141, and side walls 143 extending from the top, bottom, left, and right ends of the back wall 142 to the opening 141. In this embodiment, three insertion sections 14 are provided on the second surface 112 side, and three copper bars 2 can be supported on the second surface 112 side in a stacked state with gaps in between.

[0016] Note that a restricting portion 144 for restricting the vertical movement of the inserted copper bar 2 is provided in the insertion portion 14 of the example shown in FIG. 2. The restricting portion 144 in this example is a plate-like restricting piece that protrudes inward from the upper and lower side walls 143, and two are provided on each side wall 143, but the shape of the restricting portion 144 is not limited to this.

[0017] As shown in FIG. 3, the insertion portion 13 and the insertion portion 14 are arranged back to back with each other via a partition portion 15 that forms the back walls 132 and 142. Thereby, using one copper bar support member 1, the copper bars 2 connected to the different-system branch breaker groups 5 and 7 on the first surface 111 side and the second surface 112 side can be supported respectively.

[0018] The distribution board 3 using the copper bar support member 1 will be described. As shown in FIG. 4, the distribution board 3 of the embodiment includes a first system having a branch row including a first main breaker 4 and a first branch breaker group 5 connected to the first main breaker 4, and a second system having a second main breaker 6 and a second branch breaker group 7 connected to the second main breaker 6, and both are provided on one board.

[0019] As shown in FIG. 3, the first branch breaker group 5 of the embodiment is connected to a first bus bar 21 which is a copper bar 2. The first bus bar 21 is inserted and supported at the longitudinal end thereof in the insertion portion 13 provided on the first surface 111 side of the copper bar support member 1.

[0020] On the other hand, the second branch breaker group 7 of the embodiment is connected to a second bus bar 22 which is a copper bar 2. The second bus bar 22 is inserted and supported at the longitudinal end thereof in the insertion portion 14 provided on the second surface 112 side of the copper bar support member 1.

[0021] In this way, as shown in FIGS. 3 and 4, the bus bar 21 belonging to the first system of branch columns and the bus bar 22 belonging to the second system of branch columns can be held using one copper bar support member 1 in a state separated from each other by the partition wall portion 15. At this time, if the partition wall portion 15 is set to the minimum thickness necessary for insulating the bus bars 21 and 22, the bus bars 21 and 22 can be installed at the closest possible distance while maintaining their insulation properties.

[0022] Therefore, it becomes possible to provide the copper bar support member 1 capable of saving space and reducing the number of parts, and the distribution board 3 using the same.

[0023] Also, the insertion portions 13 and 14 are provided with back walls 132 and 142 and side walls 133 and 143, and have a structure capable of supporting the copper bar 2 from four directions of up, down, left, and right. Thereby, the copper bar support member 1 capable of stably supporting the copper bar 2 can be obtained, and the dropping of the copper bar 2 during and after construction can be suppressed regardless of the positional relationship between the gravity direction and the insertion direction of the copper bar 2.

[0024] As described above, the present invention has been described by taking the embodiments as examples, but the present invention is not limited to the above embodiments and can be in various forms.
