摘要:
A joining assembly for fixing a flexible tube at a plate shaped holder. The joining assembly comprises first and second sleeve members made of plastic material and adapted to be joined by snap-lock means so as to form a closed sleeve clampingly receiving the flexible tube, and a bracket made of plastic material and adapted to engage the closed sleeve so as to fix it in a hole of the holder.
摘要:
A threaded element of plastic material for a joining assembly has a uniquely formed thread profile of a small profile angle between 30° and 50° and a rounded crest of a relatively large radius of curvature. The gap between the revolutions of the thread is of a volume which exceeds that of the thread. In order to provide for a specific cutting geometry of the thread profile the threaded element comprises a plurality of angular segments which are radially offset with respect to each other such that adjacent angular segments provide cutting edges. Furthermore, a tool and a method for making such a joining assembly are disclosed.
摘要:
A blind rivet for a threaded joint between a support member and a mounting member consists of a body of elastic material and a sleeve of metallic material. The body is formed as a sleeve-shaped shank adapted to be inserted into a mounting hole of the support member. The shank has a mounting flange and a folding zone adapted to be folded into a fold by a folding operation. The mounting flange and the folding zone are adapted to be supported against opposite sides of said support member. The sleeve of metallic material is disposed within the body. There are provided means for preventing twisting and torsional deformation of the body.
