First Claim
1. A connector assembly comprising:
- a first connector including a generally rectangular housing for carrying first electrical contacts, said housing having an access channel for receiving a lever assembly;
said lever assembly having a generally U-shape with opposite extending end portions;
a drive gear carried on the inner portion of each end portion, said drive gear having a lever lobe extending from one side and a plurality of drive teeth extending from another side;
a pair of mating gears rotatably carried by said first connector, each mating gear having a lever lobe extending from one side and a plurality of mating teeth extending from another side, said mating gears having their mating teeth in mating relationship respectively with said drive teeth of said drive gears;
a second connector defining a generally rectangular header for carrying second electrical contacts for respective connection to said first electrical contacts in response to said second connector being fully engaged with said first connector;
said header including a pair of cam tracks on each longitudinal side of the header for respectively receiving the lever lobes of the drive gears and mating gears;
said lever assembly having a first position whereat said header is in an unengaged position with respect to said first connector;
said lever assembly is rotatable to a second position whereat said drive gears and associated mating gears are moved to cause said lever lobes within said cam tracks to move said header to said fully engaged position;
said first connector includes a first blocking member for preventing the lever assembly from moving from the first position to the second position prior to engagement of the first and second connectors and a second blocking member for preventing said lever assembly from moving in a direction opposite the direction from the first position to the second; and
said first blocking member is positioned on an inner surface adjacent one of said lever lobes and said second connector includes a release member positioned adjacent said cam track associated with said one of said lever lobes for releasing said blocking member to permit movement of said lever assembly to the second position.

Abstract
The present disclosure provides an electrical connector assembly having electrical connectors that are matingly connected and disconnected by operation of a lever actuator of one of the connectors. The lever is pivotally connected to one of the connectors and includes a drive gear at an end thereof. Each drive gear has gear teeth and a cam projection. The gear teeth of the drive gear mesh with gear teeth of a follower or mating gear pivotally mounted on the housing of the connector carrying the lever. The mating gear also includes a cam projection. The other connector has cam grooves positioned to engage with each cam projection such that movement of the lever causes drive gear to pivot all the cam projections to engage cam grooves and move the connectors to a fully mated condition.

7. A connector assembly comprising:
-
a first connector including a housing for mounting first terminals;
said first connector housing having a first side and a second side opposite said first side, each of said first and second sides of said first connector housing including a follower gear pivotally mounted thereto and having gear teeth at one end and a cam projection at another end;a second connecter including a housing for mounting second electrical terminals for respective connection to said first terminals upon mating of first and second connectors;
said second connector housing including a first side and a second side opposite said first side and a pair of spaced apart cam grooves on each of said first and second sides of said second connector housing; anda lever movable from a first position to a second position and including two arms, each arm mounted to opposite sides of said first connector housing and including an end portion, each end portion including a drive gear having gear teeth at one end and a cam projection at another end;
said gear teeth of each of said drive gears positioned in engaging mating relation with said gear teeth of a corresponding follower gear such that drive gears and follower gears can be pivoted by movement of said lever;with said lever is in said first position, each cam projection is in a position to be received in a respective cam groove and movement of said lever from said first position to said second position causes cam projections received in said cam grooves to bring first and second connectors together to a fully mated position; wherein said first connector includes a first releasable blocking member for preventing the lever from moving from the first position to the second position prior to first connector contacting second connector and a second blocking member for preventing said lever from moving in a direction opposite the direction from the first position to the second while in the first position; and wherein said first blocking member is positioned on an inner surface adjacent one of said cam projections and contacting relation therewith and said second connector includes a release member positioned adjacent said cam groove associated with said one of said cam projections for releasing said blocking member to permit movement of said lever to the second position. - View Dependent Claims (8, 9, 10, 11, 12)
