  • Patent number: 9054438
    Abstract: A connector terminal includes a main body, a support leg, and a resilient portion. The main body includes a contact portion making contact with a first side of a male connector terminal of a male electric connector, a spring portion facing the contact portion and making contact with the second side of the male connector terminal, a support portion supporting the spring portion, and a space-limiter (joint portion) restricting a space between the contact portion and the support portion from spreading. The support leg is adapted to be fixed at one of the ends thereof. The resilient portion connects the other end of the support leg and the contact portion to each other and is resiliently deformable in accordance with deflection of the main body.
