A lever-type connector has two housings (10, 20) and a lever (40) with a cam for facilitating the connection of the housings (10, 20). The connector is configured so that a connection resistance between the housings (10, 20) and an operation resistance on the lever (40) reach their maximums at subst
A lever-type connector has two housings (10, 20) and a lever (40) with a cam for facilitating the connection of the housings (10, 20). The connector is configured so that a connection resistance between the housings (10, 20) and an operation resistance on the lever (40) reach their maximums at substantially the same time. Thus, a separate resistance generator is unnecessary, and an operator is less likely to erroneously stop the connecting operation upon an increase in the operation resistance caused by a separate resistance generator. Accordingly, the two housings (10, 20) can be connected properly with high reliability.

1. A lever-type connector, comprising:first and second housings connectable with each other, a lever rotatably mounted on the first housing and formed with a cam means, a mating cam means provided on the second housing and engageable with the cam means to display a cam action, wherein: the lever is
1. A lever-type connector, comprising:first and second housings connectable with each other, a lever rotatably mounted on the first housing and formed with a cam means, a mating cam means provided on the second housing and engageable with the cam means to display a cam action, wherein: the lever is positioned initially at a connection starting position for engaging the mating cam means with the cam means, the lever having an operable portion that is movable away from center axes of the two housings along a connecting direction to an upright position and then is movable substantially towards the center axes of the two housings along a connecting direction to an opposite side to bring the lever to a connection ending position, thereby properly connecting the two housings, and a peak being defined where a connection resistance between the two housings and an operation resistance on the lever both are set to reach maximum values while the lever is rotated from the upright position to the connection ending position, so that the operation resistance is reduced when the lever is rotated beyond the peak. 2. The lever-type connector of claim 1, further comprising a tab in the second housing for contacting and resiliently deforming a resilient contact piece in the first housing, the operation resistance on the lever being set to reach its maximum when the tab resiliently deforms the resilient contact piece.3. The lever-type connector of claim 2, wherein the operation resistance on the lever is set to reach its maximum when the tab resiliently deforms the resilient contact piece to a maximum extent.4. The lever-type connector of claim 1, wherein a resilient seal is provided on at least the first housing to provide a sealing function at least when the housings are connected properly.5. The lever-type connector of claim 4, wherein the operation resistance acting on the lever is set to reach its maximum when the resilient seal is being deformed.6. The lever-type connector of claim 1, further comprising a lock for locking the lever when the lever is displaced to the connection ending position.7. The lever-type connector of claim 1, wherein the cam means has a play area for permitting rotation of the lever without advancing the connection of the two housings substantially immediately before where the lever reaches the connection ending position.8. The lever-type connector of claim 1, wherein a start locking means is provided for locking the lever substantially at the connection starting position.9. The lever-type connector of claim 8, wherein a start unlocking means is provided for disengaging the start locking means, thereby allowing the lever to rotate for connecting the two housings.10. A housing for a lever-type connector connectable with a mating housing,a lever rotatably mounted on the housing and formed with a cam means for engaging a mating cam means on the mating housing to display a cam action, wherein: the lever is positioned initially at a connection starting position with the cam means aligned for engaging the mating cam means, at least a portion of the lever being movable substantially away from center axes of the two housings along a connecting direction to an upright position and then being movable substantially towards the center axes of the two housings along a connecting direction to an opposite side to bring the lever to a connection ending position, thereby substantially properly connecting the two housings, and a peak where a connection resistance acting between the two housings and an operation resistance acting on the lever are both at their maximums while the lever is rotated from the upright position towards or to the connection ending position, so that the operation resistance is reduced when the lever is rotated beyond the peak.
