  • Patent number: 7270553
    Abstract: In a pivotal lever-type connector, at the same time when a male connector housing is fitted into a predetermined position relative to a female connector housing, so that the female connector housing and the male connector housing are brought into a provisionally-fitted condition, distal end portions of elastic retaining arms, after abutting respectively against male connector housing-side inclining surfaces, are guided respectively onto female connector housing-side inclining surfaces, and slide on the respective female connector housing-side inclining surfaces in respective directions to decrease the distance therebetween, so that a pivotal lever is pivotally moved, thereby canceling the provisionally-fitted condition.
    Type: Grant

  • Patent number: 7258557
    Abstract: In a pivotal lever-type connector, a pivotal lever includes a metallic pivotal lever body which is disposed generally in straddling relation to a hood portion of a female connector housing, and can be engaged with engagement projections of a male connector housing, and a synthetic resin-made pivotal movement operating portion mounted on the pivotal lever body to cover a pivotally-moving end portion of the pivotal lever body. The pivotal movement operating portion has synthetic resin-made elastic retaining arms molded integrally with a body of this operating portion.

  • Patent number: 6817900
    Abstract: A connector 1 has a resilient terminal locking arm 12 having a forward half 31 and a rear half 33, the forward half 31 partially defining a wall partition wall 11 for a terminal accommodating space 7 of a housing 2 of the connector, the rear half having a fore end to serve as a terminal stopping surface 32. The terminal stopping surface 32 is positioned at a middle of the terminal locking arm 12 in a longitudinal direction of the connector. A pair of the forward arm halves 31 are provided to be opposed to each other in a transverse direction of the connector, and the terminal stopping surface 32 extends across a width of the terminal accommodation space 7 between the pair of forward halves.
