1. An extendible electrical socket comprising:
a mother socket (10) including a mother connecting portion (11), a first conducting plate (12) and a second conducting plate (13) respectively electrically connected to two electrodes of a power source; said first conducting plate (12) having a first output contactor (121) and said second conducting plate (13) having a second output contactor (131) respectively formed in the mother connecting portion (11); a mother output terminal (14) formed on the mother connecting portion (11) and having a first engaging portion (141) formed on said mother output terminal (14); and
at least a daughter socket (20) including a first conductor (21), a second conductor (22), and a socket (23); said socket (23) including a plurality of socket holes (231, 232) respectively corresponding to a plurality of conducting clips (231a, 232a) formed in said daughter socket (20), a first said conducting clip (231a) electrically connected to a first said socket hole (231), a second conducting clip (232a) electrically connected to a second said socket hole (232); said daughter socket (20) further including a daughter input terminal (24) having a daughter engaging member (25) formed on said daughter input terminal (24) defining a daughter engaging groove (250) between said daughter engaging member (25) and said daughter input terminal (24); said daughter engaging groove (250) operatively engaged with said mother output terminal (14) of said mother socket (10) by engaging a second engaging portion (251) of said daughter engaging member (25) with said first engaging portion (141) of said mother output terminal (14) for extendibly connecting said mother socket (10) with said daughter socket (20); a first input contactor (211) of said first conductor (21) of said daughter socket (20) electrically contacted with said first output contactor (121) of said first conducting plate (12) of said mother socket (10), and a second input contactor (221) of said second conductor (22) electrically contacted with said second output contactor (131) of said second conducting plate (13) of said mother socket (10); said daughter socket (20) further including a daughter connecting terminal (26) having an output engaging portion (261) formed on said daughter connecting terminal (26) and having a coupling portion (261a) formed on said output engaging portion (261); said output engaging portion (261) of a first said daughter socket (20) operatively engaged with said daughter engaging member (25) of a second said daughter socket (20) by engaging said coupling portion (261a) of said first daughter socket (20) with said engaging portion (251) of said second daughter socket (20); a first output contactor (212) of first said daughter socket (20) electrically contacted with a first input contactor (211) of second said daughter socket (20); a second output contactor (222) of first said daughter socket (20) electrically contacted with a second input contactor (221) of second said daughter socket (20), whereby a power source will be extendibly connected and output from said mother socket (10) through each said daughter socket (20).
