  • Publication number: 20110014822
    Abstract: A connector includes a terminal electrically connected to an end of an electric wire, and a connector housing which accommodates the terminal and the electric wire. The terminal is capable of being fastened to an opposite member by means of a fastening member so that the terminal is electrically connected to the opposite member. The connector housing includes a housing arm which supports the terminal so as to be displaceable in a direction in which the fastening member is fastened to the opposite member.

  • Patent number: 7438570
    Abstract: An interlocking male terminal 45 is contained in a slider 4, and an interlocking female terminal 35 is contained in a male connector 3 so as to be opposed to the interlocking male terminal 45. When fitting a female connector 2 and the male connector 3 together, a connecting lever 23 is pivotally moved through an angle of about 90 degrees in a direction of arrow M, and then the slider 4 is advanced in a direction of arrow A. As a result, the female and male connectors 2 and 3 are completely fitted together, and also the interlocking male terminal 45 is connected to the interlocking female terminal 35, so that wires 5 are electrically connected respectively to wires 6. The interlocking female terminal 45 is formed integrally with the slider 4, and the interlocking female terminal 35 is formed integrally with the male connector 3, and therefore a lever fitting-type connector 1 can be reduced in size or length, and besides the number of the component parts thereof can be reduced.
