PLUG HAVING BUILT-IN CONNECTOR

摘要

This plug having a built-in connector, in which a connector inserted into and connected to an adaptor in a receptacle is included and which is connected to the receptacle, comprises: a housing positioned at the rear end side in the insertion direction of the connector and holding the connector; a spring for pushing the housing in the insertion direction; a holder positioned in front of a flange section formed in the housing and coupled to the housing; and an outer casing member. The holder is pushed by the spring through the flange section to contact a protrusion formed on an inner surface of the outer casing member, thereby being retained, the housing is movable with respect to the holder in only one direction perpendicular to the insertion direction, and the holder is movable with respect to the outer casing member in only one crossing direction which is perpendicular to the insertion direction and crosses the one direction. Even though a floating structure for the connector is employed, the connector can be prevented from being rotated.
