A service plug includes a first connector housing, a second connector housing, and a lever that is rotatable about a rotational shaft on the second housing. The lever is movable between a first operating position and a second operating position. The second connector housing is in a non-fitted state, when the lever is in the first operating position. The second connector housing is in a fitted state, when the lever is in the second operating position. The lever includes a preventive wall at a terminating end portion of the cam groove.

A lever (11) swings from a fitting start position to a fitting completion position on a housing (10) and has a cam groove (68). In the swinging process, a cam follower (21) of a counterpart housing (14) and cam (55) of a moving plate (13) advance a fitting operation between the housings (10) and (14) to move the moving plate (13) from a moving start position to a moving completion position. A detachment regulating portion (69) locks the cam (55) at the fitting start position to regulate detachment of the moving plate (13) from the hood (26). The lever (11) is swung from the fitting start position in an opposite direction of the fitting completion position, and has a detachment allowing position separating the cam (55) from the detachment regulating portion (69) to allow the moving plate (13) to detach from the hood (26).

A connector includes a first-housing, a second-housing, a shroud, and a stacked-gear. The stacked-gear is moveably mounted to the first-housing. The stacked-gear engages a first-gear-rack on the second-housing and a second-gear-rack on the shroud. The second-housing is mated with the first-housing when the shroud is moved along a mating-axis of the connector. The stacked-gear engages at least two teeth on the first-gear-rack and on the second-gear-rack when the second-housing is mated with the first-housing. A rotation of the stacked-gear is greater than ninety degrees when the shroud is moved from an unmated-position to a mated-position. The stacked-gear initially engages a first-side of a first-tooth of the first-gear-rack when the first-housing receives the second-housing. A uniform mating-force is maintained as the shroud is moved from an unmated-position to a mated-position. A mechanical advantage to produce the mating-force is increased as the shroud is moved from an unmated-position to a mated-position.

An electrical connector comprises a contact-carrying body having a plurality of electrical terminals, a slide member slidably mounted within the contact-carrying body and having a rack, an upper body mounted to the contact-carrying body, and a lever pivotally mounted on the upper body. The lever has a toothed wheel engaging the rack; movement of the lever between an inoperative position and an operative position moves the slide member between a retracted position and an advanced position. The lever has arms and a handle. Each arm of the lever has a telescoping structure including a first arm portion and a second arm portion slidably mounted to the first arm portion and connected to the handle. A movable portion including the second arm portion of each arm and the handle is movable with respect to each of the first arm portions between an elongated lever position and a shortened lever position.

A plug connector includes a housing having a mating end and a cable end. The mating end is configured to be mated with a header connector in a mating direction. A tab terminal is held in the housing at the mating end. The tab terminal has a leading edge configured to be mated with the header terminal of the header connector when the plug connector is mated to the header connector. The leading edge is tapered such that the tab terminal sequentially mates with the header terminal during mating.

A lever (22) is formed with first driving portions (27) to move sliders (35) from a connection end position to an unlocking position in the process of rotating the lever (22) from a connection position to a switch position. Second driving portions (28) push the sliders (35) parallel to one another from the unlocking position to a connection start position in the process of rotating the lever (22) from the switch position to an initial position and move away from the sliders (35) as the lever (22) rotates from the initial position to the switch position with the sliders (35) located at the connection start position. Locking portions (33) restrict rotation of the lever (22) toward the connection position by being locked to the sliders (35) with the sliders (35) located at the connection start position and the lever (22) located at the switch position.

An electrical connection element is for a power connector. The power connector includes an electrical component having a number of first electrical mating members. The electrical connection element comprises: a housing including a number of second electrical mating members structured to be electrically connected to the number of first electrical mating members; a contact assembly enclosed by the housing and being electrically connected to the number of second electrical mating members; and an operating mechanism for opening and closing the contact assembly. The contact assembly is structured to electrically connect and disconnect power while the number of first electrical mating members remain mechanically coupled to the number of second electrical mating members.

An electrical connector includes a connector housing configured to receive a corresponding mating connector, a cable guide cover attached to the connector housing, and a mate assist system for assisting in mating to the corresponding mating connector. The mate assist system includes a lever moveable to assembly, open, and closed positions. The lever includes gear means connected with a slider in the connector housing. The lever moves the slider to a first, second, and third position. The lever is releasable and attachable to the connector housing only in the assembly position. The cable guide cover is attachable to the connector housing only when the lever is in the closed position. The slider has a releasing means cooperating with a releasing means of the corresponding mating connector to unblock the slider while mating and enabling movement of the lever to the closed position, thereby moving the slider to the third position.

A connector includes a first housing, a second housing, a mate assist slider, and a cam gear. The first-housing has a first outer surface. The second housing is configured to mate with the first housing, and the second housing includes a pin extending from a second outer surface. The connector also includes a mate assist slider moveable from an unmated position to a mated position. The connector also includes a cam gear mounted to the first outer surface. The cam gear moves in response to a movement of the mate-assist-slider from the unmated position to the mated position. The cam gear has a cam slot with an inertial detent. A vibratory feedback is provided to an assembler indicative of a properly positioned connector housing when the pin is moved past the inertial detent.

It is aimed to provide a connector capable of suppressing opening deformation of an operating member and avoiding enlargement. A U-shaped operating member (11) is arranged to straddle a housing (10) and is linearly movable from an initial position to a connection position while arms (37) slide on the housing (10) and proceeds with a connecting operation of the housing (10) and a mating housing (12) by cam engagement of the arms (37) with the mating housing (12) during a movement. The housing (10) includes support shafts (18) and the arms (37) include linearly extending long grooves (39) into which the support shafts (18) are inserted to be slidable in contact therewith. The support shaft (18) includes jaws (19) and the long groove (39) includes an engaging edge (44) configured to contact the jaws (19) in an opening direction of the arm (37).
