This type of copper strip does not have a constant thickness, and in particular, the spacing within the distribution board is not uniformly determined. Nevertheless, it is necessary to ensure that the long copper strip remains parallel and firmly supported and fixed without wobbling. This support member is called a cleat in the industry.

てボルト止めする形式を採用していた。 In order to meet these demands, the present applicant has proposed that the cleat is divided into two parts, consisting of a pair of opposing cleat members, and that both cleat members are attached to both sides of the copper strip in the width direction in a state perpendicular to the longitudinal direction of the copper strip. Placed in
Both cleat members clamped the copper strip from both sides in the width direction and secured it with bolts.

た。 In order to ensure electrical insulation and mechanical strength, each cleat member is formed into a thick plate using Bakelite and then cut into appropriate lengths.
Next, a plurality of fitting grooves are cut in the width direction on the opposing surfaces of each cleat member in accordance with the thickness and spacing of the copper strips. In this way, the fitting grooves of both cleat members were fitted into the ends of the copper strip in the width direction, and both cleat members were bolted together with the copper strip interposed therebetween.

合する嵌合溝７を形成したものとなつている。 Other conventional examples include Japanese Utility Model Publication No. 49-24977 and especially Japanese Patent Application Laid-open No. 50-22292. As explained herein with reference to the accompanying drawings, the device includes a pair of cleat members 2a that function substantially in the same manner as described above, and each cleat member 2a has both side walls 3 and a connecting wall 4 that connects one end of these cleat members 2a to the other side walls 3. It is a plastic molded product formed into a U-shaped cross section, and has fitting grooves 7 formed in both side walls 3 into which the ends of the copper strip 1 in the width direction fit.

The Bakelite cleat mentioned above has the advantage that the fitting groove can be cut to match the thickness and spacing of the copper strips. However, the cleat member is solid and heavy, and since Bakelite has moisture absorption properties, it requires waterproofing treatment with silicone and is expensive.
Furthermore, since the fitting groove must be cut and machined across the width direction of the cleat member, this cutting process requires time and effort, and it is difficult to achieve the height and planar accuracy of the groove bottom. Therefore, when the edge of the copper strip in the width direction is received and pressed down at the bottom of the fitting groove, one of the copper strips may wobble in the width direction due to uneven contact, making it impossible to fix the copper strip in the longitudinal direction. It has been recognized that there is a disadvantage in that if the copper strips become insufficient, the copper strips will be tilted and the supporting form will not be able to achieve parallelism between the copper strips.

に致命的な欠点がある。 On the other hand, in the conventional cleats of the kind seen in the aforementioned Japanese Utility Model Publication No. 49-24977 and Japanese Patent Application Laid-open No. 50-22292, each cleat member 2a is not solid but has a U-shaped cross section, and a fitting groove Since the grooves 7 are integrally molded from plastic at predetermined intervals, they are lightweight and can be mass-produced at low cost, and the fitting grooves 7 can also be molded with high precision.
However, in such a plastic molded product, since all parts up to the fitting groove 7 are integrally molded, there is a fatal drawback in that it cannot accommodate changes in the thickness of the copper strips 1 or differences in arrangement spacing.

実に規制できないおそれがある。 Even if each cleat member 2a is formed into a U-shaped cross section and the fitting grooves 7 are later cut into both side walls 3 according to the arrangement spacing of the copper strips 1, etc., firstly, Strength is insufficient. That is, in order to securely fix the copper strip 1, bolt insertion holes 9 were made in the connecting wall 4 of each cleat member 2a, and these bolt insertion holes 9 were used to hold both cleat members 2a with the copper strip 1 sandwiched between them. When the bolts 10 are fastened in this state, the side wall 3 tends to be bent inward or outward if the bolts 10 are fastened strongly. Moreover, both cleat members 2a tend to be warped and deformed in a direction in which they float apart from each other at locations other than the bolt fastening locations. Therefore, while still supporting the copper strip 1,
In particular, the bending deformation of the side wall 3 causes the copper strips 1 to tilt, making it difficult to maintain parallelism between the copper strips 1. Also, only the groove bottom 7a of the fitting groove 7 is connected to the edge 1a of the copper strip 1 in the width direction.
Therefore, the contact area with the edge 1a is insufficient, and if warping deformation occurs at locations other than the aforementioned bolt fastening locations, the copper strip 1
may wobble in the width direction, making it impossible to reliably control displacement in the longitudinal direction.
