Operable wire connector
An operable wire connector comprises an insulating housing ( 1 ), an operating handle ( 2 ) rotatably mounted inside the insulating housing ( 1 ), a transmitting piece ( 3 ), an electric conductor ( 4 ), an elastic clamping piece ( 5 ) with a fixed portion ( 51 ) connected to the electric conductor ( 4 ) and an elastic free portion ( 52 ) resisted by the transmitting piece ( 3 ), and a cover ( 6 ) assembled with the insulating housing ( 1 ); an adjustable gap is formed between the elastic free portion ( 52 ) and the electric conductor ( 4 ) for receiving a wire, and the gap will continuously be present due to the action of a rotation limiting portion ( 12 ). The operating handle ( 2 ) is pulled reversely, so that the wire comes into contact with the electric conductor ( 4 ); when the user pulls and turns up the operating handle ( 2 ) again, there is no need to continuously use force, and the wire will be take out easily.
