Lever-equipped connector and connector assembly

A lever-equipped connector to be connected to a mating connector such that at least one terminal provided in a connector housing is substantially completely connected to at least one corresponding terminal of the mating connector if a lever displaceably provided on the connector housing to be connected to the mating connector is displaced from a pre-connection position to a connection position,

• the lever including at least one detecting member attached to the lever to allow a movement from a standby position to a detection position only when the lever substantially is located at the connection position,
• the detecting member including a head portion arranged to be at least partly exposed from the lever for operation of the detecting member and at least one leg portion formed to extend from the head portion to be at least partly inserted into an insertion recess of the connector housing when the lever is located at the connection position, and
• at least one deformation suppressing portion for suppressing deformation of the leg portion in an opening direction when the detecting member is operated with the lever located at the pre-connection position being provided between the connector housing and the leg portion.
