Signal adaptation plug

A signal adaption plug, comprising:

• a longitudinally extended stage having a connector formed on a longitudinal end thereof adapted for releasable coupling with a socket and having at least one accommodation groove formed therein, said accommodation groove having a contact surface, said contact surface having a plurality of gap grooves formed therein, said stage having a plurality of hook holes formed adjacent said contact surface;
• at least one cover plate coupled to said stage and being situated on one side of said accommodation groove, said cover plate being fixed on said stage by a retaining stage, said cover plate being affixed to said retaining stage and extends angularly therefrom for releasable engagement with a locking member of a plug received within said accommodation groove, said retaining stage having a plurality of embedding hooks extending from opposing sides thereof for respective engagement with said hook holes;
• and,
• a terminal assembly composed of a plurality of pin terminals and installed inside said stage, said pin terminals each having at least one first contact part in said accommodation groove and a second contact part disposed in said connector of said stage, said first contact part of said pin terminals passing through a respective gap groove of the contact surface of said stage.

A signal adaption plug, comprising:

• a longitudinally extended stage having a connector formed on a longitudinal end thereof adapted for releasable coupling with a socket and having a plurality of longitudinally spaced accommodation grooves formed therein, each of said accommodation grooves having a contact surface, said contact surface having a plurality of gap grooves formed therein, said stage having a pairs of transversely directed lower tracks respectively formed in opposing side walls bordering each said accommodation groove and a pair of transversely directed upper tracks respectively formed in opposing side walls bordering each said accommodation groove and spaced from said corresponding lower tracks;
• a plurality of cover plates, each said cover plate having a first end hingedly coupled to said stage on one side of a respective one of said plurality of accommodation grooves, said cover plate being reversably positionable from a first position levelly covering a respective accommodation groove to an angularly directed second position for releasable engagement with a locking member of a plug received within said respective accommodation groove, each said cover plate having a pair of shafts extending from opposing sides thereof, said pair of shafts being respectively disposed in a corresponding pair of said upper tracks when said cover plate is in said first position, said pair of shafts being respectively displaced to a corresponding pair of said lower tracks when said cover plate is displaced to said second position for holding said cover plate in said second position;
• and,
• a terminal assembly composed of a plurality of pin terminals and installed inside said stage, said pin terminals each having a plurality of first contact parts respectively positioned in said plurality of accommodation grooves and a second contact part disposed in said connector of said stage, each said first contact part of said pin terminals passing through a respective gap groove of a corresponding contact surface of said stage.
