Claim:
An interlocking connector comprising: a plug assembly including a front hollow seat, an inner seat receiving therein a pair of conductive connecting pins, and a rear housing having an extension power line; a core wire of said power line is electrically connected with said conductive connecting pins; a front portion of said inner seat is received in said front hollow seat, while a rear portion of said inner seat is received in said rear housing, said inner seat at least is provided with two mutually parallel grooves to respectively receive said conductive connecting pins, and is provided in said front portion with two through holes in corresponding by position respectively to said conductive connecting pins; a liftable and closable lid is attached on top of said inner seat, and a recessed space is formed at the bottom of said inner seat in opposition to said lid; said front hollow seat is slipped over said front portion of said inner seat and is provided with a pair of holes in corresponding by position respectively to said two through holes, and is provided in corresponding by position to said recessed space of said inner seat with an elastic strip thereof, said elastic strip is provided on a front thereof with a triangular engaging block having a slope and is provided on an end thereof with a raised press block; said rear housing is slipped over said rear portion of said inner seat, and is provided in corresponding by position to said press block with an opening to allow said press block to protrude out of a surface of said press block, so that said press block transmits a force toward said recessed space to displace said triangular engaging block; and an appliance socket unit mounted on an appliance in need of electric power, the appliance socket unit has a housing which has an entry with a shape meeting that of said front hollow seat for inserting of said front hollow seat, and is provided therein with a pair of conductive pins; when said front hollow seat of said plug assembly is inserted, said pair of conductive pins having ends are extended through said through holes and said holes to electrically connect said conductive connecting pins; said entry is provided on and inner wall thereof in corresponding by position to said triangular engaging block of said elastic strip with a triangular engaging hole, in order that when said plug assembly is inserted, said triangular engaging block is engaged in said triangular engaging hole to lock said plug assembly together with said appliance socket unit; in pressing said press block, said triangular engaging block is displaced to relieve locking with said triangular engaging hole, thereby said plug assembly is extracted out of said appliance socket unit; wherein said front hollow seat of said plug assembly is provided around on an outer surface thereof with a stopping rib, a front edge of said rear housing is adapted to being stopped by said stopping rib.
