Patent ID: 6997731

Claim:
A seismic cable coupling comprising: a) a cable having a first connector body; b) a second connector body adapted for mechanical and electrical coupling to the first connector body; c) a first coupling ring rotatably mounted on the first connector body, the first coupling ring including a first ring body having a first longitudinal projection and a second longitudinal projection, the first longitudinal projection having an interior surface including a first angled groove, the second longitudinal projection having an exterior surface including a first raised stud; and d) a second coupling ring coupled to the second connector body, the second coupling ring including a second ring body having a third longitudinal projection and a fourth longitudinal projection, the third longitudinal projection having an interior surface including a second angled groove, the fourth longitudinal projection having an exterior surface including a second raised stud, wherein the first ring body couples to the second body when the second raised stud aligns with the first groove and the first raised stud aligns with the second groove, and wherein relative rotation of the first ring body to the second ring body provides an axial coupling force.
