Abstract: A combined connector assembly provided for quick, secure fluid and electrical connection includes a socket assembly and plug assembly. The socket assembly can be supported on various structures as a wall outlet or an appliance attachment by means of an adapter assembly. Interlocking means are incorporated with electrical contacts between socket and plug assemblies so that the fluid and electrical connection between the socket and plug assemblies can be quickly and securely established, eliminating the risk of accidental detachment of the plug assembly from the socket assembly. Seals and covers are provided to prevent fluid leakage from the assembly in both connected and disconnected positions. The combined connector assembly of the present invention can be advantageously used to connect an appliance to a water supply and drain system which pumps water to and removes water under vacuum from the appliance through a single hose in a pre-programmed manner.
