  • Publication number: 20060110976
    Abstract: A terminal for preventing incorrect insertion into a housing and a method of correctly inserting a terminal into a housing of a connection. The terminal includes a frame that is adapted to be received into a cavity in the housing and a wire operatively connected to the frame. A protrusion, which extends from the frame, includes a leading side, a top side, and a trailing side. The protrusion is configured to only allow a desired orientation of the terminal when inserted into the cavity. The frame and protrusion are formed from a single piece of sheet metal. The method includes orienting the terminal such that a protrusion disposed on the terminal is aligned with a slot formed in a cavity in the housing and inserting the terminal into the cavity in the housing such that the protrusion passes through the slot.

  • Patent number: 7048568
    Abstract: A housing assembly for a pair of electric connectors includes a first housing with a lock arm to lock the first housing inserted into a second housing, and a reinforcing member held by the first housing. The reinforcing member can be pushed into the first housing only when the first housing and the second housing are completely properly fitted together. The coupling strength between the housings is enhanced by the coupling strength of the reinforcing member, and the operator can easily and properly judge the proper fitting of the housings on the basis that the reinforcing member can be pushed in. As the first housing holds the reinforcing member, the fitting work can be done smoothly and reliably. Both housings can be made slimmer. This assembly allows a single-action fitting wherein the first housing can be fitted in the second housing by pushing only the reinforcing member.

  • Patent number: 6899554
    Abstract: A lever-type electrical connector assembly reduces the connection mating forces required to mate female and male connectors. The connector assembly employs a first connector with cam follower projections, a base housing with cam grooves and a sliding guide rail, a slide lever housing including a sliding projection and a sliding guide rail, and a cover housing pivotally mounted on the base housing, the cover housing having a sliding projection. As the cover housing is rotated from an open to a closed position, it engages the sliding projection in the guide rail to permit rotation of the lever housing. This rotation engages the sliding projection in the guide rail. As the lever housing is rotated from an open to a closed position, it rotates the cam grooves to engage the cam follower projections thereby drawing the first connector into the base housing to a connected position.
