<p>PROBLEM TO BE SOLVED: To absorb and lighten the stress generated by the thermal expansion and contraction, etc., of an insulated bus, by dispensing with a mobile contact using parts such as a multiram band, etc. SOLUTION: For a T-shaped block 20, a conductor leading bar is molded inside by epoxy resin or the like, and collar-shaped flanges 27 are made to project on both sides of the base of the projection. The projection of a T-shaped bushing 20 is inserted into the through hole 26 made in an outer board 22, and each flange 27b of the bushing 20 abutted against the rib of this through hole 26 is caught by and fixed each slidably to a fixing metal fitting 24 in the shape of roughly U when viewed from the side.</p> |
