Abstract: In a first housing configuring a fitting structure, an accommodation portion opening in a front-rear direction and configured to accommodate a second housing, and an incorrect fitting-prevention rib protruding toward an inside of the accommodation portion and extending in a fitting direction are provided therein. In the second housing fitting with the first housing, a fitting concave portion being concave in a protrusion direction of the incorrect fitting-prevention rib is provided, while a front retainer having a fitting groove being concave in the protrusion direction is attached to the second housing. The fitting concave portion has a predetermined width in an up-down direction and is configured to receive the incorrect fitting-prevention rib inside the accommodation portion, and the fitting groove and the incorrect fitting-prevention rib are fitted with each other within the width of the fitting concave portion.

Abstract: A connector includes a housing fitting to an accommodation portion of a jig having the accommodation and a positioning rib. A side retainer being displaceable to a regular retaining position and a temporarily retaining position is provided in the housing. A guide surface being slidingly contactable with the positioning rib in a state of being at the regular retaining position is provided in the side retainer. The guide surface is positioned at further lower side with respect to the positioning rib as the side retainer is positioned at further front side. In a state in which the fitting of the housing has been completed, the side retainer is positioned at the temporarily retaining position while being sandwiched in the height direction by the positioning rib and an inner wall surface of the accommodation portion so as to restrict a displacement to the height direction.

Abstract: A connector includes a housing and a lock arm that extends from the housing and is engageable with a counterpart connector. The lock arm includes a first arm a has a shape of a cantilever beam and has a locking hole for being engaged with the counterpart connector at a free end side of the first arm, and a second arm that extends from an end portion on the free end side of the first arm and is capable of releasing the engagement by bending the first arm around a fixing end of the first arm. The locking hole has a hole of which the size in a width direction orthogonal to an extending direction of the first arm becomes larger as a measurement position of the size of the hole gets closer to the free end from the fixing end.

Abstract: A connector includes a lever drawing and fitting a first housing and a second housing by moving from a temporary lock position to a final lock position. The lever includes a lever-side lock portion elastically deformable in a first direction away from a surface of the first housing, and including a reinforcing rib that enhances rigidity against a deformation of the lever-side lock protrusion. The first housing includes a housing-side lock portion which locks the lever-side lock portion when the lever is in the temporary lock position, which inhibits movement of the lever to the final lock position during locking, and which permits the lever to move to the final lock position when the locking is released. The second housing includes a lock releasing portion which pushes the lever-side lock portion in the first direction so as to release the locking.

Abstract: A connector includes a lever attachable to a first housing to draw and fit the first housing and a second housing by rotating around a rotating axis from a temporary lock position to a final lock position. The lever includes: a positioning portion including a pair of wall surfaces which extend toward the first housing and which are spaced at a predetermined distance from each other in a first direction parallel to the rotating axis; and a lever side lock portion. The first housing includes: a reception portion which receives the positioning portion so as to hold the pair of wall surfaces in the first direction; and a housing-side lock portion to which the lever-side lock portion is locked in a state in which the positioning portion has been received in the reception portion and when the lever is in the final lock position.

Abstract: The present invention prevents two connector housings of a connector from being in a half-fitted condition by increasing restoring force which separates the two housing. A connector includes: a first connector housing including a lock projection; a second connector housing to be fitted to the first connector housing and integrally including a lock arm which is elastically deformed by the lock projection and is engaged with the lock projection; a lock ensuring member including a body which is attached to the second connector housing and movable between an allowing position and a preventing position, and an interference arm which is integrally provided on the body and includes a pressing projection. The pressing projection presses the lock arm while the lock projection deforms the lock arm at the allowing position, and the interference arm abuts the lock arm so as to prohibit the lock arm from deforming in the preventing position.
