Abstract: A cable television apparatus includes a coupled-line directional coupler. The coupled-line directional coupler includes a coupled-line directional coupler body, an input side, an output side and a coupled side. The coupled-line directional coupler body receives a cable television video-audio-data signal through the input side or the output side.

Abstract: A refrigerant socket includes an accommodating body and a pipeline assembly. The pipeline assembly includes a refrigerant pipe connecting to the accommodating body and having an inner section inside the accommodating body and an outer section outside the accommodating body; a switch placed at the inner section and away from a free end thereof, the switch being used to selectively allow or block a flow inside the refrigerant pipe; a refrigerant pumping pipe communicating between the free end of the inner section and the switch; and at least one joint communicates between the free end of the inner section and the switch. Therefore, even if the diameter of the refrigerant pipe does not match an air conditioner indoor unit, connection can still be made without the need of removing the original piping, thereby avoiding wasting refrigerant.
