A lever (24) is formed with a separating cam surface (30) and an escaping space (31) disposed in a region more distant from a rotary shaft (13) than the separating cam surface (30). The separating cam surface (30) presses cam projections (23) of a moving plate (18) in a direction away from the rotary shaft (13) to separate both housings (10, 40) in the process of rotating the lever (24) to an initial position with the both housings (10, 40) connected. The cam projections (23) are accommodated into the escaping space (31) while being separated from the separating cam surface (30) in the process of rotating the lever (24) from the initial position to a connection position with the both housings (10, 40) separated and the moving plate (18) located at a protection position.

A lever-type connector includes a housing, a lever and a cover. The housing is to be fitted with a mating housing. The lever is pivotably mounted to the housing and fits the housing with the mating housing by pivoting. The cover is mounted to the housing to cover an outer periphery of an electric cable drawn out from the housing. The housing is provide with a deflectable lock arm. The lock arm has as a base end, a root part integrally mounted to the housing at a side where the housing faces the cover and holds the lever at a pivoting completion position of the lever. The cover is provided with a protective wall arranged opposite to the root part of the lock arm.

A lock lever of a second connector has a first engaged part and a second engaged part. A frame of a first connector has a first engaging part and a second engaging part. The first engaging part is engaged with the first engaged part in a locked state where the lock lever is at a lock position. The lock lever has the elastic part that is elastically deformable in the horizontal direction. The elastic part has a second engaged part and is elastically deformed in the horizontal direction in the locked state to bring the second engaged part into contact with the second engaging part.

A mated connector assembly includes: a first connector assembly, comprising a plurality of first coaxial connectors mounted on a mounting structure and a first shell; and a second connector assembly, comprising a plurality of second coaxial connectors, each of the second coaxial connectors connected with a respective coaxial cable and mated with a respective first coaxial connector. The second connector assembly includes a second shell surrounding the second coaxial connectors, the second shell defining a plurality of electrically isolated cavities, each of the second coaxial connectors being located in a respective cavity. In in a mated condition the second shell resides within the first shell.

The connector assembly includes a terminal position assurance (TPA) device, and a seal retainer. A downwardly extending notch member of the seal retainer engages with a recess on an upper surface of an upper portion of the TPA device to form a cam linkage mechanism or a cam mechanical linkage for the TPA device and the seal retainer. The seal retainer, when pushed or inserted towards an outer housing, by way of the cam linkage mechanism with the TPA device, pushes the TPA device to one side such that the terminals within the outer housing remain unlocked. The seal retainer, when further pushed or inserted toward the outer housing, by way of the cam linkage mechanism, moves the TPA device laterally to an opposite side such that the TPA device blocks the terminals within the outer housing. A lower portion of the seal retainer is, at a pre-lock or full-lock position, engaged with mating locking members at a bottom portion of a terminal guidance member.

It is aimed to provide a connector capable of ensuring predetermined sealability. A connector is provided with a housing connectable to a mating housing, a seal to be mounted into the housing, and a moving member movable with respect to the housing. The seal has a sealing surface to be held in close contact with the mating housing. The moving member is arranged at a position facing the sealing surface of the seal before connection of the both housings.

A lever-type connector includes a connector body including side walls and a boss portion and a lever including a pair of arm portions, each of the pair of arm portions being provided with a boss fitting hole into which the boss portion of the connector body is to be inserted, the lever being to be rotatably attached to the connector body. The connector body and the lever includes a first and second alignment marks, the first alignment mark and the second alignment mark being visually recognizable while the lever is being attached to the connector body. The lever is, by aligning the second alignment mark with the first alignment mark, to be rotatably attached to the connector body with a position of the boss portion and a position of the fitting hole being aligned with each other, allowing the boss portion to be inserted into the boss fitting hole.

A lever is supported so as to be rotatable with respect to a housing to a temporary locking position and a main locking position. One of the housing and the lever is provided with a first locking portion capable of flexible deformation, and another is provided with a second locking portion. The first locking portion includes a first apex portion and a first locking surface that is connected to the first apex portion. The second locking portion includes a second locking surface that contacts the first locking portion and stops the lever at the temporary locking position. The second locking surface includes an inclined side that is disposed, in a state where the first locking portion has bent due to interference between the first apex portion and the second locking portion, so as to be inclined from the first apex portion toward the first locking surface.

It is aimed to connect a first housing and a second housing in an opposed state and detect connection of the housings. A lever-type connector includes a cam follower formed on a second housing and configured to connect the first and second housings by sliding in contact with a cam groove in a rotation process of a lever from an initial position to a connection position, a restricting pin provided on the first housing and arranged at a position deviated in a direction intersecting a connecting direction with respect to a virtual connection line, a restricting groove to be brought into sliding contact with the restricting pin, and a connection detector for allowing the lever to slide to a connection detecting position eccentric from a center of rotation only when the lever reaches the connection position and the first and second housings are connected in an opposed positional relationship.

A plug as an electrical connector according to the present disclosure includes a box-shaped housing and a lock lever having an arm in such a manner that a base end of the arm is rotatable, and the lock lever is configured to pull the mating housing inside the box-shaped housing. On a side face of the box-shaped housing, a projection is provided which can be hidden from the side face thereof. A recess is provided in an intermediate portion of the arm of the lock lever, and the projection can be introduced and the rotation of the lock lever in the one direction can be prevented. The recess includes a bottom wall (first inner wall) and a side wall (second inner wall) formed therein which can be pressed by the projection by a rotational force of the lock lever in one direction being divided.
