Patent ID: 7678499

Claim:
A battery receptacle, comprising: an insulative casing including top and bottom walls that cooperate to define an accommodating space therebetween for accommodating a battery unit; a positive electrode having a first end portion that extends into said accommodating space and that is adapted to contact electrically the battery unit, and a second end portion that is disposed externally of said accommodating space and that abuts against said top wall of said casing; a negative electrode having a first end portion that extends into said accommodating space and that is adapted to be connected electrically to the battery unit, and a second end portion that is disposed externally of said accommodating space and that abuts against said top wall of said casing; and an interface assembly disposed on said top wall of said casing, and including an insulative body having top and bottom surfaces, and a peripheral surface that interconnects said top and bottom surfaces, an anode terminal having a first end portion that extends through said insulative body and that projects from said top surface of said insulative body, and a second end portion that projects from said bottom surface of said insulative body and that is in electrical contact with said second end portion of said positive electrode, a cathode terminal provided on said peripheral surface of said insulative body, a contact element having a first end portion that extends through said insulative body and that is in electrical contact with said cathode terminal, and a second end portion that projects from said bottom surface of said insulative body and that is in electrical contact with said second end portion of said negative electrode, and an insulating protrusion provided on said bottom surface of said insulative body, and abutting against said second end portion of said positive electrode, thereby maintaining a gap between said cathode terminal and said second end portion of said positive electrode.
