Abstract

A coupling assembly includes a female member having a bore and a male member capable of being received in the bore of the female member. A trigger assembly is disposed between the male and female members and includes an actuator, housing, and biasing member. The male member includes an engagement mechanism to engage the trigger assembly and facilitate axial movement of the actuator. Axial movement of the actuator induces expansion of the biasing member and the engagement of the actuator and the male member. Accordingly, the male member is urged or propelled into the bore of the female member upon expansion of the biasing member. To disconnect, the male and female members are utilized to return the trigger assembly to an inactivated position.
