A lever-type connector includes a mating housing having a cam boss and a release rib portion, a housing that has a support shaft and a temporarily locked portion and that is fitted into and removed from the mating housing, and a lever having a temporary locking arm portion where a temporary locking portion is temporarily locked to the temporarily locked portion and is unlocked from the temporarily locked portion by the release rib portion, the lever having a cam groove including a boss pick-up portion and a boss holding portion that engage with the cam boss, and the lever being rotated from a temporary locking position to a fitting completion position via the support shaft to cause the cam groove to engage with the cam boss, thus moving the mating housing toward the housing and fitting the mating housing and the housing to each other.

A connector includes a second housing fittable with a first housing, a slide member movable relative to the first housing along a connector fitting direction, a transmission gear member rotatably supported by a support shaft provided on the first housing, a first rack gear portion provided on the slide member along the connector fitting direction, a driven gear portion of the transmission gear member rotated by movement of the first rack gear portion in the connector fitting direction, a main drive gear portion of the transmission gear member provided on a side opposite to the driven gear portion with the support shaft interposed therebetween, and a second rack gear portion provided on the second housing along the connector fitting direction, and movable relative to the first housing along the connector fitting direction by rotation of the main drive gear portion.

A female housing includes a pair of guide rails that face a connection position assurance (CPA) member in a width direction orthogonal to an insertion direction. The CPA member includes a pair of restricting portions that are positioned below the guide rails, respectively. The pair of restricting portions restrict movement of a CPA lock portion in an upward direction by coming into contact with the pair of guide rails, respectively, in a detection member moving state in which the CPA member moves between an initial position and a fitting assurance position with respect to the female housing, and release the restriction of the movement in the upward direction by the pair of guide rails in an assurance position state in which the CPA member is positioned at the fitting assurance position with respect to the female housing.

A lever-type connector has a lever that rotates about a shaft on a first housing between a retracted position and a connection start position. The first housing and a second housing are connected by rotation of the lever from the connection start position. A detector is movable between a standby position and a detection position with respect to the lever. The lever includes a lock on an end separated from the shaft. The second housing includes a full locking portion to engage the lock when the housings are connected. The detector locks the lock at the standby position and becomes movable to the detection position when the full locking portion engages the lock. The first housing includes a housing-side lock, and the lever includes a lever-side lock that locks the housing-side lock at the retracted position. The lever-side lock is at a position different from the lock of the lever.

A power supply circuit breaking device includes a first connector housing, a second connector housing, a main lock unit locking in a finally fitted state in which the second connector housing is completely fitted to the first connector housing, a sub-lock unit locking in a temporarily fitted state in which a part of the second connector housing is fitted to the first connector housing, a main switch unit switched on in the finally fitted state and the temporarily fitted state, and a sub-switch unit switched on in the finally fitted state and switched off in the temporarily fitted state. The sub-lock unit includes a sub-lock claw formed in the first connecter housing, and an operation portion provided in the second connector housing and having an engaging plate portion engaged with the sub-lock claw in the temporarily fitted state.

A lever-type connector has a lever (24) with a cam groove (28) curved to approach a center of rotation (13) of the lever (24) from an entrance (28E) to a back side. Rotation of the lever (24) from an initial position to a connection position causes cam projections (23) of a moving plate (18) to displace in the cam groove (28) and to approach the center of rotation (13) of the lever (24) while sliding in contact with a cam pin (41) of a female housing (40). The cam projections (23) displace in an escaping space (31) of the lever (24) without changing a positional relationship with respect to the center of rotation (13) of the lever (24) as the lever (24) is rotated from the initial position to the connection position in a state out of contact with the cam pin (41).

A lever-type connector (F) includes a housing (10) formed with support shafts (26) and rotation restricting portions (20F, 20R). A lever (30) includes plate-like arms (31) and is rotatable between an initial position where the lever waits at the start of connection to a mating connector (M) and a connection position where the connection to the mating connector (M) is completed. The lever (30) is mounted by fitting bearing holes (34) of the arms (31) to the support shafts (26). Reverse rotation restricting projections (45) project from surfaces of the arms (31) facing the housing (10) toward the housing (10) and are configured to be locked to the rotation restricting portions (20F, 20R) to restrict rotation of the lever (30) at the initial position toward a side opposite to the connection position.

A lever-type connector includes a housing fitted to and separated from a mating-connector housing, a lever supported by the housing and fits and separates the housings to and from each other through a rotation operation, and a cable cover mounted on the housing and covers a rear surface of the housing. A support shaft is provided in one of the housing and the lever, and a bearing portion having a shaft-sliding groove is provided in the other. A cam follower is provided in one of the lever and the mating-side connector, and a cam groove is provided in the other. A locking portion is provided in one of the lever and the housing, and a temporary locked portion and a complete locked portion are provided at positions in the other one. The locking portion is capable of locking and separating each the temporary locked portion and the complete locked portion.

A plug connector comprises a first plug, a second plug, and a securing device configured to mechanically secure the first plug to the second plug. The second plug has a receptacle with a ramp surface and a locking surface. The securing device has a lever pivotably mounted on the first plug. The lever pivotably bears a connecting element which has a securing cam on a free end of the connecting element. The receptacle of the second plug receives the securing cam and the ramp surface of the receptacle cooperates with the free end of the connecting element to forcibly guide the securing cam behind the locking surface of the receptacle when the first plug and the second plug are plugged together.

A connector includes a second housing fittable with a first housing, a slide member movable relative to the first housing along a connector fitting direction, a transmission gear member rotatably supported by a support shaft provided on the first housing, a first rack gear portion provided on the slide member along the connector fitting direction, a driven gear portion of the transmission gear member rotated by movement of the first rack gear portion in the connector fitting direction, a main drive gear portion of the transmission gear member provided on a side opposite to the driven gear portion with the support shaft interposed therebetween, and a second rack gear portion provided on the second housing along the connector fitting direction, and movable relative to the first housing along the connector fitting direction by rotation of the main drive gear portion.
