Abstract
Abstract A releasable lever-mounted lock mechanism for securing an electrical connector lever in a pre-set position on a connector body. The lever has cam slots and is located on a first connector. The lock in a preferred form comprises an L-shaped, deflectable arm formed in the sidewall of the lever. A free end of the arm has a ramp-shaped stop portion. The second end of the arm is joined to the lever sidewall in cantilever fashion such that the arm deflects relative to the lever. A flat surface of the stop snaps behind an edge of the first connector in the preset position, with the arm in an undeflected position. The lever is thereby locked in the pre-set position, allowing a second connector with cam posts to be brought into initial mating contact with the first connector. The cam posts enter the slots of the lever. A release projection on the L-shaped lock arm is contacted by the shroud of the second connector. This deflects the lock arm, releasing the stop from the edge of the first connector. The lever can then be pivoted and the cam interaction between the lever slots and second connector side posts draws the connectors into electrical engagement.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
132 words
A lock assembly for holding a connector lever in an open, pre-set position on a connector housing to receive a mating connector, the lock assembly comprising: a deflectable member attached to a sidewall of the lever; a stop on the deflectable member for engaging the connector housing in the pre-set position and preventing the lever from being rotated to a closed position; and a release projection on the deflectable member located forwardly of the stop in the lever pre-set position, the release projection being located to contact the mating connector when the mating connector is mated with the connector housing, whereby the mating connector forces the release projection and deflectable member away from the connector housing to disengage the stop from the connector housing thereby releasing the lever from the pre-set position.
Claim 2
Dependent Claim
132 words
A lock assembly for holding a connector lever in an open, pre-set position on a connector housing to receive a mating connector, the lock assembly comprising: a deflectable member attached to a sidewall of the lever; a stop on the deflectable member for engaging the connector housing in the pre-set position and preventing the lever from being rotated to a closed position; and a release projection on the deflectable member located forwardly of the stop in the lever pre-set position, the release projection being located to contact the mating connector when the mating connector is mated with the connector housing, whereby the mating connector forces the release projection and deflectable member away from the connector housing to disengage the stop from the connector housing thereby releasing the lever from the pre-set position.
Claim 3
Dependent Claim
25 words
The lock assembly of claim 1 wherein the projection is a rounded dimple on an inner surface of the deflectable member facing the connector housing.
Claim 4
Dependent Claim
13 words
The lock assembly of claim 2 wherein the dimple has a hemispherical shape.
Claim 5
Dependent Claim
15 words
The lock assembly of claim I wherein the deflectable member is integral with the lever.
Claim 6
Dependent Claim
25 words
The lock assembly of claim 4 wherein the deflectable member is L-shaped and the release projection is located at a crux of the L-shaped member.
Claim 7
Dependent Claim
23 words
The lock assembly of claim 5 wherein the L-shaped deflectable member is contained within the sidewall of the lever in its undeflected state.
Claim 8
Dependent Claim
19 words
The lock assembly of claim 5 wherein the stop is located on a free end of the L-shaped member.
Claim 9
Dependent Claim
13 words
The lock assembly of claim 1 wherein the stop has a ramp portion.
Claim 10
Dependent Claim
41 words
The lock assembly of claim 8 wherein the ramp portion faces the connector housing and a flat surface of the stop perpendicular to the deflectable member abuts a portion of the connector housing to lock the lever in the open position.
Claim 11
Dependent Claim
20 words
The lock assembly of claim 1 wherein there is a deflectable member on each of two sidewalls of the lever.
Claim 12
Dependent Claim
180 words
A connector assembly comprising: a first connector having a housing and a pivotable lever attached to the housing; a second connector having a shroud for receiving the first connector housing and cam posts adapted to be received in slots in the lever such that pivoting the lever from a first, pre-set position to a second position electrically mates the two connectors; a deflectable lock arm on the lever, the lock arm being deflectable relative to the lever and having an inner surface, a fixed end, and a free end; a stop on the inner surface of the free end of the lock arm for engaging a portion of the first connector housing to secure the lever in the pre-set position; and a release projection on the inner surface of the free end of the lock arm spaced from the stop, the release projection being located so as to be contacted by the shroud of the second connector to deflect the lock arm away from the first connector housing and thereby allow the lever to be pivoted to the second position.
Claim 13
Dependent Claim
180 words
A connector assembly comprising: a first connector having a housing and a pivotable lever attached to the housing; a second connector having a shroud for receiving the first connector housing and cam posts adapted to be received in slots in the lever such that pivoting the lever from a first, pre-set position to a second position electrically mates the two connectors; a deflectable lock arm on the lever, the lock arm being deflectable relative to the lever and having an inner surface, a fixed end, and a free end; a stop on the inner surface of the free end of the lock arm for engaging a portion of the first connector housing to secure the lever in the pre-set position; and a release projection on the inner surface of the free end of the lock arm spaced from the stop, the release projection being located so as to be contacted by the shroud of the second connector to deflect the lock arm away from the first connector housing and thereby allow the lever to be pivoted to the second position.
Claim 14
Dependent Claim
37 words
The connector assembly of claim 11 wherein the deflectable lock arm comprises an arm formed in a sidewall of the lever, the inner surface of the free end of the lock arm facing the first connector housing.
