ABSTRACT:
A mechanical coupling including a plug assembly and a receptacle assembly. The plug assembly has a first latching body rotatably connected to a coupling nut such that the coupling nut is capable of rotating relative to the latching body. The coupling nut includes an interior threaded portion which is threaded to an exterior threaded portion of an inner body. The coupling nut and the inner body are in constant threaded engagement in a sealed chamber. The receptacle assembly has a second latching body capable of interconnecting with the first latching body. The plug assembly includes a first coupling member and the receptacle assembly includes a second coupling member. The first and second coupling members are coupled together by further rotating the coupling nut which advances the first coupling connector towards the second coupling connector.
