Coupling assembly

A coupling assembly comprising:

• a first member extending along an axis from a leading end to a trailing end, a first exterior surface extending from the leading end and a second exterior surface spaced from the first exterior surface by a retaining formation, the retaining formation including a ramp extending outward from the first exterior surface and at least two grooves, wherein each groove is at least partially defined by converging surfaces;
• a second member having a receiving end and a receiving portion sized to receive the first member, the receiving portion including a first inwardly facing cylindrical surface adjacent the receiving end sized to receive the retaining formation of the first member, and an inwardly facing annular groove including a chamfer extending radially outward from the cylindrical surface and away from the receiving end;
• and
• a locking member moveably received within the inwardly facing annular groove of the second member, the locking member sized to receive the first exterior surface of the first member and to be moved to a radially outward position by the ramp upon movement of the first member into the receiving portion of the second member, the locking member biased radially inward into a groove in the retaining formation to become positioned between a converging surface on the retaining formation and the chamfer upon further movement of the first member into the receiving portion and to be progressively received in additional grooves on the retaining formation of the first member if the first member is further inserted into the second member.

• a second member having a receiving end and a receiving portion sized to receive the first member, the receiving portion including a first inwardly facing cylindrical surface adjacent the receiving end and sized to receive the retaining formation of the first member, and an inwardly facing annular groove including spaced apart first and second tapered surfaces extending outwardly from first inwardly facing cylindrical surface;
• and
• a number of locking member segments moveably received within the inwardly facing annular groove of the second member, the locking member segments sized to receive the first exterior surface of the first member and to be moved to a radially outward position by the ramp upon movement of the first member into the receiving portion of the second member, the locking member segments biased radially inward by a resilient member into a groove in the retaining formation to become positioned between a converging surface on the retaining formation and the second tapered surface of the second member upon further movement of the first member into the receiving portion and to be progressively received in additional grooves on the retaining formation of the first member if the first member is further inserted into the second member.

• and
• a number of locking balls moveably received within the inwardly facing annular groove of the second member, the locking balls positioned to receive the first exterior surface of the first member and to be moved to a radially outward position by the ramp upon movement of the first member into the receiving portion of the second member, the locking balls biased radially inward into a groove in the retaining formation to become positioned between a converging surface on the retaining formation and the chamfer upon further movement of the first member into the receiving portion and to be progressively received in additional grooves on the retaining formation of the first member if the first member is further inserted into the second member.

A coupling assembly comprising:

• a first member extending along an axis from a leading end to a trailing end, a first exterior surface extending from the leading end and a second exterior surface spaced from the first exterior surface by an annular cavity extending inwardly from one of the first and second exterior surfaces;
• a second member having a receiving end and a receiving portion sized to receive the first member, the receiving portion including a ramp tapering inwardly and away from the receiving end and two or more outwardly facing annular grooves wherein each groove is at least partially defined by converging surfaces;
• and
• a number of locking member segments moveably received within the annular cavity of the first member, the locking member segments sized to be moved to a radially inward position by the ramp upon movement of the first member into the receiving portion of the second member, the locking member segments biased radially outward by a resilient member into a groove in the second member to become positioned between a converging surface and the cavity of the first member upon further movement of the first member into the receiving portion and to be progressively received in additional grooves in the second member if the first member is further inserted into the second member.
