An operating member (11) includes a plate-like arm (37) configured to cover an outer surface of a housing (10) and is displaceable to an initial position and a connection position. A resilient piece (48) is provided on an outer edge of the arm (37) and projects along a plate surface of the arm (37). The resilient piece (48) restricts a displacement of the operating member (11) from the initial position to the connection position by resiliently locking a lock receiving portion (32) while being unlocked from the lock receiving portion (32) by being pressed by an unlocking portion (15) of a mating housing (12) and allowing displacement of the operating member (11) to the connection position. The resilient piece (48) is shaped to be delectable and deformable in a direction along the plate surface of the arm portion (37) when being pressed by the unlocking portion (15).

An operating member (11) is displaceable to an assembled position, an initial position and a connection position with respect to a housing (10) and proceeds with a connecting operation of the housing and a mating housing (12) by cam engagement with the mating housing (12) when being displaced from the initial position to the connection position. The housing (10) includes resilient locks (25, 26) configured to restrict a displacement of the operating member (11) in a direction opposite to that from the assembled position toward the initial position by resiliently locking the operating member (11) at the assembled position and restrict a displacement of the operating member (11) in a return direction from the initial position to the assembled position by resiliently locking the operating member (11) at the initial position.

A connector includes a lever attachable to a first housing to draw and fit the first housing and a second housing by rotating around a rotating axis from a temporary lock position to a final lock position. The lever includes: a positioning portion including a pair of wall surfaces which extend toward the first housing and which are spaced at a predetermined distance from each other in a first direction parallel to the rotating axis; and a lever side lock portion. The first housing includes: a reception portion which receives the positioning portion so as to hold the pair of wall surfaces in the first direction; and a housing-side lock portion to which the lever-side lock portion is locked in a state in which the positioning portion has been received in the reception portion and when the lever is in the final lock position.

The present disclosure provides a connector assembly. The connector assembly includes a connector housing adapted to engage with a corresponding counter-connector housing. A lever including a first lever arm and a second lever arm is pivotably and sealingly mounted to the connector housing. Each lever arm includes interlocking means for connecting the first lever arm to the second lever arm at a first location. The interlocking means of each of the first lever arm and the second lever arm are configured to define complementary symmetrical surfaces that interlock with one another when the lever arms are pivotably mounted to the connector housing. On mounting the lever arms to the connector housing, the lever is configured to move about the connector housing between an open state and a closed state to secure the counter-connector housing to the connector housing.

A connector has a housing configured to mate with a second housing, a pair of slide members movably mounted on the housing, and a lever pivotably attached to the housing and slidably coupled to the slide members. Each slide member has a cam groove in a side surface which provides an angled lead-in surface into the cam groove and cam surfaces engageable with a cam follower post of the second housing. A blocking shoulder partially blocking an opening of the cam groove to prevent entry of the cam follower post unless the cam follower post is in a correct position. When the cam follower post engages the angled lead-in surface, this provides a visual and tactile indication to a user that the connector is ready to be mated with the second housing.

A lever-type connector includes a first and second connector housing, and a lever rotatably provided on the first connector housing and which can fit or separate the first and second connector housing by a rotating operation. A flexible lock arm is provided on the first connector housing. A free end side of the lock arm includes a locking part whose rear end side is capable of locking so as to be hooked to the rear end part of a locking protrusion of the lever, and a release operation part capable of releasing a locking state of the rear end part of the locking protrusion and the rear end side of the locking part. The locking part and the release operation part are provided adjacent to each other. The release operation part is positioned below the lever at a time of locking between the locking part and the locking protrusion.

This lever-type connector comprises a first part forming a base and a second part mobile in relation to the base, the first and second parts inwardly receiving first and second contact assemblies facing one another, male and female respectfully, each provided at one end with conductors to be connected, and a cam mechanism able to move the mobile part between contact disconnection and connection positions. The cam mechanism includes a lever shaped so as to be circumscribed inside the main cross-section of the connector.

An electronic device testing apparatus with a locking mechanism for locking a press head and a socket plate is provided. When an electronic device is to be tested, a lifting arm is lowered so that a contact portion is in contact with the electronic device, and a locking mechanism is actuated to detain the press head on the socket plate. A pressing force generating device exerts a pressing force onto the electronic device and the socket plate, and at least a portion of a reaction force can be directed back to the locking mechanism. The locking mechanism is adapted to detain the press head on the socket plate. When the pressing force generating device generates a predetermined pressing force to certainly establish electrical connection between the electronic device and the chip socket, the reaction force produced by the chip socket may be distributed over the locking mechanism.

A lever (40) is formed with resilient arms (48) cantilevered in a direction substantially perpendicular to rotary shafts (15) of the lever (40) and intersecting with a circumferential direction about the rotary shafts (15), and locking projections (49) projecting from extending end parts of the resilient arm pieces (48) and configured to hold the lever (40) at an initial position by entering locking holes (20) and being locked. The locking hole (20) is formed with a locking edge part (21) located on a surface of a housing (10) facing the lever (40) and configured to lock the locking projection (49) and a recess (23) formed by recessing an inner surface part on a deeper side than the locking edge part (21), and the locking projection (49) is formed with a hooking portion (53) configured to enter the recess (23) while being locked to the locking edge part (21).

An electrical connector comprises a housing and a connector position assurance device. The housing has a locking lever locking the housing to a mating housing of a mating electrical connector. The connector position assurance device is fitted on the locking lever and is pivotable in relation to the housing from a delivery position to a locking position. The connector position assurance device, when in the locking position, prevents unlocking of the locking lever when the housing is connected to the mating housing.
