Patent ID: 7594832

Claim:
A female terminal, comprising: a terminal energizing portion comprising a high conductivity material comprising a frame structure for accommodating a male terminal, the frame structure formed by bending a single plate member to have a rectangular cross section comprising a bottom surface, two side surfaces bent to be continued from the bottom surface, and an upper surface including two upper surface pieces bent to be continued from the two side surfaces respectively and a joint where the two upper surface pieces face to each other via a gap; and a terminal box comprising a material having a strength higher than that of the high conductivity material of the terminal energizing portion, the terminal box comprising a frame structure for covering the frame structure of the terminal energizing portion, the frame structure being formed by bending another single plate member to have a rectangular cross section, the frame structure comprising an upper surface, two side surfaces bent to be continued from the upper surface, and a lower surface including two lower surface pieces bent to be continued from the two side surfaces respectively and a joint where the two lower surface pieces face to each other via a gap, the terminal box comprising a spring formed integrally with the frame structure of the terminal box, the spring bent to extend from the upper surface into the frame structure of the terminal box, wherein the frame structure of the terminal energizing portion is accommodated into the frame structure of the terminal box to be engaged with each other, and the spring of the terminal box is located within the frame structure of the terminal energizing portion.
