Ball-and-socket joint

摘要

The invention relates to a ball-and-socket joint provided in the form of an insertion detent connection. Said ball-and-socket joint comprises a first fixed joint part (1) which forms a joint cup (3), and comprises a second joint part (2) which has a spherical surface (4) and which is mounted in the joint cup (3) such that it can slide. In order to develop a ball-and-socket joint in a manner which is advantageous with regard to use and which is well-disposed with regard to manufacturing techniques, the invention provides a detent ball (12) which is arranged in the center (5) of the curvature of the joint cup (3) and which, via a neck (6) that projects from the cup center, is connected to the cup (3) in order to form a single part consisting of the same material. In addition, a detent opening (7) is provided in the spherical surface (4) whose inner width (W) is smaller than the ball diameter (D), whereby the detent opening (7) forms a widened surface with its wall (8) that expands outward in the shape of a funnel. Said widened surface is provided for expanding the detent opening (7) to a diameter which snaps over the equator (9) of the detent ball (12), whereby a detent sliding surface (10) adjoins the wall (8) on the inside of the opening and is located at a distance from the spherical surface (4), said spherical surface extending concentrically thereto, which is equal to at least the length (L) of the neck.
