  • Patent number: 5713689
    Abstract: A ball joint link includes a ball stud having a stud and a ball, a cap mounted on the ball, and a rod. The ball defines a raised annular stem which fits inside a tubular portion of the rod such that the ball stud, the cap and the rod form a self-supporting sub-assembly. This sub-assembly is then placed within a mold, and a molded body is formed around the sub-assembly. A strengthening element can be disposed in the molded body around the ball stud to increase pull out resistance.

  • Patent number: 5609433
    Abstract: A ball joint link includes a ball stud, a ball cap and a strengthening element that are all insert molded in a thermoplastic body. The strengthening element is disposed around the ball stud and includes a first portion which receives the ball of the ball stud and a second portion which receives the stud of the ball stud. The strengthening element is securely anchored in the body, and the second portion of the strengthening element resists pull out forces tending to remove the ball stud from the ball joint link. The ball cap snaps in place on the ball and is substantially completely embedded within the body. Insert molding methods for forming the ball joint link are disclosed.
