  • Patent number: 9080563
    Abstract: A disclosed connector assembly for connecting abutting ends of a pair of rods includes a pair of outer clamp members, each adapted to receive one of two inner clamp members. Each inner clamp member has two opposed inner surfaces, each adapted to contact a corresponding shoulder of one of the rod ends. The assembly includes means for urging the outer clamp members toward one another. A described method for connecting the rod ends includes installing one of the inner clamp members in each of the outer clamp members and positioning the outer clamp members about the abutting ends of the rods such that the inner surfaces of the inner clamp members contact the corresponding shoulders. When the outer clamp members are urged toward one another, the inner surfaces of the inner clamp members impart forces on the corresponding shoulders that urge the ends of the rods toward one another.
