Abstract
A ball-stud joint having a flange on a stud thereof, the flange having a sloping side for making it easy to locate centrally the stud relatively to a lower die jig. The ball stud is comprised of a ball fit for pivoting movement into a major body, a stud having a plain end adapted to be formed into a rivet head to joint the stud with any counterpart, and a flange formed integrally around the stud to provide a surface coming into abutment against the counterpart. The flange has a sloping side extending radially outwardly from a flat surface facing on to the ball to an outside periphery of the flange in such a way that the sloping side comes into engagement with a slantwise bearing area on a lower die jig when the plain end of the stud is formed into rivet head.
Claims9
A ball-stud joint composed of a major body having a threaded bore adapted to connect the major body to a first counterpart, a ball stud connected to the major body, and a dust cover installed to prevent entry of dust where the major body is connected to the ball stud, wherein the ball stud is comprised of a ball fit for pivoting movement into a ball socket recessed in the major body, a stud having an end made integrally with the ball and another end adapted to fit into a second counterpart to joint the stud with the second counterpart, and a flange formed integrally around the stud to provide a surface coming into abutment against the second counterpart, and wherein the flange has a flat surface facing toward the ball and a sloping side extending radially outwardly from the flat surface to an outside periphery of the flange in such a way that the sloping side can come into engagement with a slantwise bearing area on a lower die jig while the dust cover remains installed during a riveting operation performed on the other end of the stud.
