  • Patent number: 7942708
    Abstract: An electrical connector includes a housing and a terminal. The housing includes a terminal hole and a lance portion disposed in the terminal hole. The lance portion includes a guide surface; an engaging front edge surface; and a regulated surface. The terminal includes a contact portion; a connection portion; an engaging portion; a curved portion; and a regulating portion. The engaging portion pushes the guide surface to deform and is guided with the guide surface when the terminal is inserted into the terminal hole. When the terminal is completely fitted in the terminal hole, the engaging portion faces the engaging front edge surface and engages the lance portion.
