The connection member 1 and the cable rack 4 are connected and fixed by using the rack side male screw member 12, and the connection member 1 and the cover 5 are connected and fixed by using the cover side male screw member 13. When connecting the connection member 1 and the cable rack 4, the rack-side male screw member 12 is inserted from the outside into the insertion hole 6 of the rack-side connection portion 2, and the tip of the rack-side male screw member 12 that has passed through the insertion hole 6 is connected to the cable rack. The connection member connecting portion 28 of No. 4 is screwed into the through hole 11 and fastened. When connecting the connecting member 1 and the cover 5, first, the washer 15 is inserted into the male screw member 13 on the cover side. At this time, the protrusion 14 of the washer 15 is directed to the cover 5 side. Next, the cover side male screw member 13 is inserted from the outside into the insertion hole 9 provided in the connecting piece 8 of the cover 5, and the tip of the cover side male screw member 13 passing through the insertion hole 9 is inserted into the cover side connecting portion 3 of the connecting member 1. It is fastened by screwing it into the female screw hole 7 provided in the. Also,
By thus screwing the cover-side male screw member 13 into the female screw hole 7, the head portion 30 of the cover-side male screw member 13 is
Thus, the washer 15 is pressed toward the cover 5 side, whereby the protrusion 14 of the washer 15 breaks (breaks) the non-conductive coating film on the surface of the cover 5 and cuts into the connecting piece 8.
When the washer 15 is pressed by the head portion 30, the projection 14 is held in a state of being in contact with the conductive portion (metal portion) of the cover 5. In this way, the cover 5 can be attached to the cable rack 4 using the connecting member 1.

Since a hole through which a jig is inserted is used, without drilling at the construction site,
The connection member 1 and the cable rack 4 can be connected and the connection member 1 and the cover 5 can be connected. The cable rack 4 and the cover 5 may be used after being cut to a predetermined length at a construction site. In that case, it may not be possible to secure the portion of the hole provided in advance, and in that case, the drilling process is performed at the construction site. Here, since the cable rack 4 has a certain degree of strength, it can be easily drilled, and the through hole 11 with high dimensional accuracy can be provided. Therefore, the rack side male screw member 12 can be screwed to be fastened. It is easy to surely perform the mechanical and electrical connection between the connection member 1 and the cable rack 4. However, since the connecting piece 8 of the cover 5 is not as strong as the cable rack 4 against the pressure from the side, it is not easy to make a hole at the construction site.
It is difficult to form the insertion hole 9 with high dimensional accuracy, and there is a possibility that the mechanical and electrical connection between the cover 5 and the connecting member 1 cannot be reliably performed. Therefore, in consideration of such a situation, it is preferable that the cable rack 4 and the connection member 1 are fastened by screwing the rack side male screw member 12 into the through hole 11, and the cover 5 and the connection member 1 are connected to each other by the cover side male screw member 13. It is preferable that the connecting piece 8 of the cover 5 is sandwiched and fastened by the head portion 30 and the connecting member 1. With such a configuration, even if on-site drilling is required,
A reliable mechanical and electrical connection can be made.

で、電気的な接続の信頼性が低くなる恐れがある。When using the non-conductive surface-treated cover 5, a washer 15 having a protrusion 14 is inserted into the cover-side male screw member 13 and the cover-side male screw member 13 is screwed into the female screw hole 7. By doing so, the washer 15 is pressed by the head portion 30 of the male screw member 13 on the cover side and the protrusion 14
While breaking (breaking) the non-conductive coating film on the surface of the cover 5 so as to bite into the connecting piece 8 and bring the protrusion 14 into contact with the conductive portion (metal portion) of the cover 5, By pressing the washer 15, the protrusion 14 can be firmly and surely held in contact with the conductive portion of the cover 5, and electrical connection can be ensured as compared with the case where the protrusion 14 is simply brought into contact with the cover 5. Is something that can be done. In the invention of Japanese Patent No. 2789322, the non-conductive surface treatment film of the cable rack cover is broken by the breaking claw piece, but in this case, the cable rack cover is simply brought into contact with the breaking claw piece. However, the reliability of the electrical connection may be reduced.

とができるものである。FIG. 5 shows another example of the connecting member 1. The connecting member 1 has an insertion hole 6 which is a long hole which is long in the vertical direction (longitudinal direction of the connecting member 1). Other configurations are similar to those of the connecting member 1 of the above-described embodiment, and similarly to the connecting member 1 of the above-described embodiment, they are used for mechanical and electrical connection between the cable rack 4 and the cover 5. . Since the insertion hole 6 is formed as a long hole in this connection member 1, the connection member 1 is moved in the up-down direction along the longitudinal direction of the insertion hole 6 to fix the cover 5 to the cable rack 4 at the fixed position (connection position). (Position) can be easily changed, and even if there is an interposition between the cable rack 4 and the cover 5 that protrudes above the cable rack 4, the cover 5 can be easily moved upward. It can be connected.
