形や導電接触子の摺動によって吸収することができる。As described above, in the inter-panel connection bus system of the present invention, the insulated bus and the bushing are integrated, and the insulated bus is connected at one place between the boards. The time required for on-site construction is halved, and the risks involved in construction are reduced. If an elastic solid insulator such as EP rubber is used as the insulating layer or bushing for the insulating bus, and a finger contact structure is used as the conductive contact, the thermal expansion and installation level of the board and the insulating bus will be reduced. Can be absorbed by deformation such as a bushing or sliding of the conductive contact.
