Abstract
A coupling mechanism (11) comprising a receptacle (13) having an open cavity (31) therein, a plug (15) receivable in the cavity (31), and a rotatable coupling member (17) drivingly coupled to the plug (15) and coupling the plug (15) to the receptacle (13). A locking member (19) is mounted on the coupling member (17) for rotation with the coupling member (17) and for translation relative to the coupling member (17). A spring (21) acts between the locking member (19) and the coupling member (17) and urges the locking member (19) to translate with the coupling member (17). Translation of the locking member (19) is limited so that the spring (21) is compressed to store energy. A cam track (33) and a cam follower (105) have interlocking members which are driven into interlocking relationship by the stored energy in the spring (21) when the locking member (19) and the receptacle (13 ) are in a predetermined angular position relative to each other. The interlocking members retain the locking member (19) rotation relative to the receptacle (13).
