Abstract: A connector assembly that may be used to so pivotally connect the adjoining end portions of an upper and lower string of sucker rod that are angularly disposed relative to one another within a tubing string of like angulation, that longitudinal forces may be exerted on the sucker rod strings to reciprocate the same without the sucker rod strings being subjected to an appreciable twisting stress. The connector assemblies may not only be used to connect angularly disposed strings of sucker rod at their junctions, but also to connect the lower end of the lowermost string of sucker rod to the piston rod of an elongate pump situated below the tubing string in which the sucker rods are disposed.
