Title: A CONNECTOR ASSEMBLY FOR A DRILLING APPARATUS
Abstract:
A connector assembly (10) for use with a drilling apparatus, comprises an input connector unit (12) which is connectable to a drill motor, an output connector unit (14) which is connectable to a drill pipe string and a number of shock absorption elements (16). The input and output connector units (14), (16) include top and bottom carrier plates (26) and (31), respectively. The shock absorption elements (16) are arranged adjacent one another between the carrier plates providing for absorption of both axial and rotational shock forces transmitted between the drill motor and the drill string. The connector assembly includes elongate link elements (70) extending between the top and bottom carrier plates which prevent separation of the carrier plates beyond a predetermined separation spacing limit.
