A banana plug including a body, a male portion, a female portion, and a lever. The male portion is configured to extend from the body to electrically connect with a receptacle. In one example, the receptacle is a piece of audio/video (AV) equipment. The female portion is configured to receive a wire and/or other electrical component. The lever is configured to actuate between an open position and a closed position. In the open position, the lever is configured to actuate an internal spring to receive a wire. In the closed position, the lever is configured to release the internal spring to secure and/or retain the wire via a compression force.

A cable connector comprises a housing, a conductive element fixed on the housing and connected with the cable, an elastic piece adjacent to the conductive element, detective and switch terminals fixed on the housing and connected with a pressing plate. The pressing plate is rotatable between a first position and a second position. When the pressing body is abutted at the first position by the elastic piece, a receiving gap between the elastic piece and the conductive element is closed to prevent the cable from entering, and the pressing body is abutted against the switch terminal to define a first conductive state. When the pressing body is at the second position, the receiving gap is opened to receive the cable, and the pressing body is disengaged with the switch terminal, to define a second conductive state. A connection state can be known by detecting the first and second conductive states.
