  • Publication number: 20080233789
    Abstract: In a connector lock structure 1 provided at female and male connectors which can be fitted together, the female connector 2 has an engagement portion 14, and a slide lock member 13 is supported on the male connector 3 so as to move at least in connector-inserting and connector-withdrawing directions. The slide lock member 13 includes a retaining portion 16 for engagement with the engagement portion 14, and urging member 36 for urging the slide lock member 13. When the engagement portion 14 reaches an engagement position where it is engaged with the retaining portion 16 at the time when the female and male connectors are completely fitted together, the slide lock member 13 is automatically moved by the urging member 36, so that the retaining portion 16 is engaged with the engagement portion 14.

  • Patent number: 7318271
    Abstract: A process and device for assembling a connector is provided, by which the production efficiency can be improved by preventing the problem of insertion error from occurring in a step of terminal insertion into a connector housing in the manufacturing process of the wiring harness by using an automatic assembly machine or in a step of the operation by the human hands. The process includes the steps of: provisionally locking the spacer in the connector housing; inserting a jig rod into the connector housing before inserting the terminal into the connector housing, the jig rod being for releasing the locking of the spacer which is completely locked in the connector housing; pulling the jig rod out from the connector housing; and inserting the terminal into the connector housing.

  • Patent number: 7261585
    Abstract: A press-contact connector 10 has a first member 20 which accommodates a plurality of terminals 21 having press-contact blades 21a and a second member 30 which is attached to the first member 20 and holds a plurality of wires 11 in an aligned state. The second member 30 has a plurality of retaining portions 31 capable of retaining the wires 11 respectively, formed in an approximate U shape and arranged in parallel to one another. The retaining portion 31 has claw portions 33 which are provided at inner walls 32 to lock the wire 11 in such a way as to contact with a bottom portion 31a of the retaining portion 31, and lances 34 which are provided at serial directional ends of each retaining portion 31 to urge the wire 11 in the direction of the opening of the retaining portion 31 in a cross section. Since each wire 11 is held bent by the cooperation of the claw portions 33 with the lances 34, compatibility with automation is possible and the wires 11 can be held sufficiently.
