Patent ID: 6843682

Claim:
A plug for the connection of electrical wires comprising: a casing ( 2 ) insertable into or removable from a machine side socket ( 50 ), and being divided into a wire-insertion chamber ( 22 ) and a connector-receiving chamber ( 21 ) by a partition ( 13 ), a connector ( 15 ) received in the connector-receiving chamber ( 21 ), and having a plate spring contact portion ( 19 ) at one side urging towards a connecting hole ( 23 ) of a partition ( 13 ) in communication with the wire-insertion chamber ( 22 ), and an external contact ( 16 ) at the other side connecting to a machine side terminal ( 55 ) of the machine side socket ( 50 ), and a housing ( 4 ) rotatably mounted in the casing ( 2 ), and having a projecting portion ( 35 ) projecting beyond the connecting hole ( 23 ) of the partition ( 13 ) from the wire-insertion chamber ( 22 ) when the housing is rotated to the side of the casing ( 2 ), and in which the wires ( 5 , 7 ) inserted within the wire-insertion chamber ( 22 ) are pressed into the connecting hole ( 23 ) by the rotation of the projecting portion ( 35 ) of the housing ( 4 ) towards the casing ( 2 ), the wires ( 5 , 7 ) are bent to clamp in between the inner wall of the projecting portion ( 35 ) and connecting hole ( 23 ), the wires ( 5 , 7 ) projecting beyond the connecting hole ( 23 ) along the surface of the projecting portion ( 35 ) being resiliently connected to the plate spring contact portion ( 19 ), and whereby the wires ( 5 , 7 ) are electrically connected to the machine side terminals ( 55 ) when the casing ( 2 ) is inserted into the machine side socket ( 50 ).
