COL LET-LIKE CONNECTING CLOSURE OF PLASTIC TUBES, PARTICULARLY OF AIR DISTRIBUTION SYSTEM OF AUTOMOBILES

摘要

This collet-like connecting closure for plastic tubes consists of a brace arranged in the inner space of the basic body (1) where the inner space consists of an input hole (3) passing through a transient ring (4) which is linked to the inner cone (6) and the cylinder area (8) terminating in the bottom (9), in which there is a centring hole (10) for the plastic tube (18). Between the transient ring (4) and the inner cone (6) there is a catch stop (5) which is perpendicular to the longitudinal axis (O) of the basic body (1), which is in contact with the contact ring (16) of the clamping cog (14) of the collet (12). The length of the wall of the inner cone (6) is at least twice the length of the conical area (15) of the collet (12) and the distance of the face of the clamping cog (14) from the intersection of the inner cone (6) with the wall (7) of the cylindrical area (8) is at least half the diameter of the cord of the plastic ring (17).IMAGE
