Preloaded connector has grooves for applying axial force on one of cooperating pin and box members after engagement to modify axial length of portion of members, wherein preload subsists on load-bearing surfaces after release of axial force

摘要

The connector has grooves (7) for applying, after engagement of cooperating pin and box members (4,3), a sufficient axial force on at least one of the members to modify plastically the axial length of a portion of the members, wherein a preload subsists on load-bearing surfaces (5,9,10,13) after release of axial force.
