Abstract
A bending resistant structure includes a rod (1) which is sealed in a casing (6), said casing receiving a double frusto-conical shaped wedging member (2,3,4) which applies jamming stresses to the rod. The wedging member is formed by a resin mass (2) moulded on the end of the rod (1), a resilient cap (3) covering the resin mass (2), and a thin metal sheathing (4) shrink-fitted over the cap (3), said wedging member being sealed in an associated casing (6), the structure being particularly resistant to high bending moments. Application to electric insulators and more particularly to those of the line-post type.
