• the present disclosure relates to the field of wire harness connection technologies, and specifically, to a connector, a connector assembly, and a vehicle.
• a lever (pull rod) connector assembly usually includes a first housing (female housing), a second housing (male housing), and a pull rod, where a lever is pivotally connected to a housing by a pivot mechanism, and the lever has a primary locking position (pre-locking position) and a secondary locking position (locking position) relative to the housing.
• a cam member arranged on the lever is fitted with a cam follower arranged on the housing to pull the lever from the primary locking position to the secondary locking position, so that the female housing is firmly connected to the male housing.
