Lever-type connector with a peak operation resistance shortly before complete connection

A lever-type connector, comprising:

• first and second housings connectable with each other;
• a lever supported pivotally on the first housing, the lever having at least one cam surface with an open starting end, a closed terminus and a curved shape between the starting end and the terminus, the curved shape being configured such that a distance from a center of rotation of the lever to the cam surface gradually decreases between the staring end and the terminus;
• at least one follower provided on the second housing and being engageable with the cam surface so that the housings are connected as the lever is pivoted;
• and
• a resistance means formed on the cam surface closer to the terminus than to the starting end for giving a peak operation resistance to the lever when the lever is pivoted to a position before the housings are connected properly and so that operation resistance to the lever decreases continuously from the position of peak operation resistance to a position where the housings are connected properly.
