Abstract: A lever-coupled connector includes a male connector having latch pins, a female connector having pin guiding recesses into which the latch pins are to be received, a fitting lever of synthetic resin rotatably attached to the female connector, the lever having driving cam grooves for the latch pins and initial position holding protrusions to be engaged with the female connectors. In a state where the initial position holding protrusions are engaged with the connector to prevent the lever from being rotated, when the male connector is inserted into the female connector, the latch pins release the protrusions from engagement with the female connector to permit the fitting lever to be rotatable. Thus, the initial position of the lever rotatably attached to the connector can be assured without using any spring.

Abstract: A corner structure of a resinous molded part includes a base portion and a pair of lever portions which are formed integrally with the base portion. The molded part is provided with cut-outs which are arranged at corners where the base portion intersects the lever portions. A thickness of a portion outside the recess is established to be larger than a thickness of another portion inside the cut-out. With the establishment of the thickness, the amount of the inward inclination of the lever portions derived from the differential shrinkage can be reduced since they are pulled outwardly due to the increased thickness of the outside portion, when the part is cooled.

Abstract: Disclosed is an engagement drive cam to establish an initial engagement position of a pair of connector housings at the time of engaging the pair of connector housings having the engagement drive cam. The engagement drive cam having cam grooves is arranged on a female connector housing so as to be turnable around a support shaft. Driven pins entering into the cam grooves are arranged on a male connector housing A. Colliding stepped portions for colliding against the drive pins are arranged at entrance portions of the cam grooves, so that the colliding stepped portions are on a line of engagement direction passing through the support shaft.

This bearing device is capable of holding an axis around which the lever rotate at a first position and a second position. The lever-coupling-type connector further includes a driving pin and a cam groove. This cam groove has an opening for receiving the driving pin. A lever-coupling-type connector further includes a projection and a recess provided for the lever to engage with the projection. This recess is capable of engaging with the projection when the axis is located at the first position, but the recess is not engaged with the projection when the axis is located at the second position.

Abstract: Connectors with a lever in which a pair of male and female connectors are mated with and disconnected from each other by rotating the lever. The lever having cam grooves and a lock portion is rotatably attached to the female connector. Cam pins are attached to the male connector. When both connectors are initially mated with each other, the cam pins engage with the cam grooves, and when the lever is rotated in a direction in which both connectors are mated with each other, the male connector moves toward the female connector. An elastic locking member is interposed between the lever and the female connector. An operational portion, reverse spring portions for urging the lever toward a direction opposite to that in which both connectors are mated, and lock spring portions to be engaged with the lock portion of the lever so as to maintain the lever in a locked position, are all integrally formed in the elastic locking member.

Abstract: The low-operating-force connector consists of a pair of female and male housings. The male housing has on the opposite sides driven pins, while the female housing has pin guide grooves for the driven pins. A cam member is rotatably mounted on the female housing, which consists of levers each including a cam groove and a lever handle connecting the levers. The housings are fitted with or separated from each other through rotation of the cam member. A pair of resilient locking pieces are provided on the outer periphery of the male housing, the locking pieces each including an engagement projection, while a corresponding pair of engagement portions are provided on the lever handle. Springs are so provided between the levers of the cam member and the female housing as to urge the cam member into an upright opened position. On completion of the coupling of the female and male housings, the cam member is locked by the engagement between the engagement projections and portions.

Abstract: A connector device for connecting and disconnecting female and male connectors by use of a fitting operation lever which allows easy and accurate confirmation of the incomplete fitting of the connectors to thereby prevent such incomplete fitting. The device includes a fitting operation lever (5), which is rotatably disposed in a female connector (A) and has a driving groove (6) in the front end portion thereof, and a driven pin (11) which is provided in a male connector (B) and is engageable with the drive groove (6). The connecting device connects the female and male connectors (A) and (B) with each other and disconnects them from each other upon rotation of the fitting operation lever (5). When the connectors are only partially connected to each other, there is some space for free and easy movement in the operation lever which allows the lever (5) to rotate in the reverse, un-locking direction due to its own weight. Thus, the incomplete connection can be visually detected.
