  • Publication number: 20140057480
    Abstract: A connector can prevent, at a low cost, a phenomenon that a crack develops in a resin molded member to which a screwing plate portion of a terminal fitting is fixed due to a bending displacement of the screwing plate portion caused by fastening force of the screwing when the screwing plate portion is screwed to a terminal stage. A plate portion fixing portion 31, to which a screwing plate portion 11 of a terminal fitting 10 is fixed, of the connector housing 30 has a terminal escape space 31a adjacent to the screwing plate portion 11 on a destination side in a direction of fastening to a terminal stage 40. The terminal escape space 31a permits a bending displacement of the screwing plate portion 11 in the fastening direction.
