Abstract
Abstract A zero insertion force electrical connector is provided for a flat cable. The connector includes a dielectric housing mounting a plurality of terminals. The housing has a front end with an opening for receiving an end of the flat cable in engagement with contact portions of the terminals. An actuator is pivotally mounted relative to the housing for floating movement between a first position allowing free insertion of the flat cable into the opening and a second position biasing the cable against the terminals. A cam surface on the actuator abuts a counter cam surface on the housing as the actuator rotates and translates about a moving pivot from its first position to its second position sandwiching the end of the flat cable between the contact portions of the terminals and the actuator.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
197 words
A zero insertion force electrical connector for a flat cable, comprising: a dielectric housing mounting a plurality of terminals in a generally parallel array, the housing having opposite sides and a front end with an opening between the sides for receiving an end of the flat cable in engagement with contact portions of the terminals; a pressure plate pivotally mounted relative to the housing for floating movement between a first position allowing free insertion of the flat cable into the opening and a second position biasing the cable against the terminals, the pressure plate having an extension on its rearward end for movement beneath an overhanging shelf means on the housing; and a forwardly facing cam surface on the pressure plate for abutting a rearwardly facing cam surface on the housing as the pressure plate is rotated about a moving pivot from its first position to its second position causing substantial translational movement of the pressure plate relative to the housing and causing the extension of the pressure plate to advance beneath the overhanging shelf means on the housing, sandwiching the end of the flat cable between the contact portions of the terminal and the pressure plate.
Claim 2
Dependent Claim
197 words
A zero insertion force electrical connector for a flat cable, comprising: a dielectric housing mounting a plurality of terminals in a generally parallel array, the housing having opposite sides and a front end with an opening between the sides for receiving an end of the flat cable in engagement with contact portions of the terminals; a pressure plate pivotally mounted relative to the housing for floating movement between a first position allowing free insertion of the flat cable into the opening and a second position biasing the cable against the terminals, the pressure plate having an extension on its rearward end for movement beneath an overhanging shelf means on the housing; and a forwardly facing cam surface on the pressure plate for abutting a rearwardly facing cam surface on the housing as the pressure plate is rotated about a moving pivot from its first position to its second position causing substantial translational movement of the pressure plate relative to the housing and causing the extension of the pressure plate to advance beneath the overhanging shelf means on the housing, sandwiching the end of the flat cable between the contact portions of the terminal and the pressure plate.
Claim 3
Dependent Claim
42 words
The zero insertion force electrical connector of claim 1 wherein each of said terminals is bifurcated to define a contact branch and a support branch, the support branches of the parallel array of terminals forming said overhanging shelf means on the housing.
Claim 4
Dependent Claim
47 words
The zero insertion force electrical connector of claim 1 wherein at least one of said cam surfaces has a cam profile to effect the rotational movement of the pressure plate about the moving pivot and the substantial translational movement of the pressure plate relative to the housing.
Claim 5
Dependent Claim
36 words
The zero insertion force electrical connector of claim 3 wherein at least one of said cam surfaces has a plurality of discrete cam sections to define said cam profile to effect said pivoting and translational movements.
Claim 6
Dependent Claim
141 words
A zero insertion force electrical connector for a flat cable, comprising: a dielectric housing mounting a plurality of terminals, the housing having a front end with an opening for receiving an end of the flat cable in engagement with contact portions of the terminals; an actuator pivotally mounted relative to the housing for floating movement between a first position allowing free insertion of the flat cable into the opening and a second position biasing the cable against the terminals; and a cam surface on the actuator for abutting a counter cam surface on the housing as the actuator is rotated about a moving pivot from its first position to its second position, causing the actuator to rotate and translate relative to the housing and sandwiching the end of the flat cable between the contact portions of the terminals and the actuator.
Claim 7
Dependent Claim
141 words
A zero insertion force electrical connector for a flat cable, comprising: a dielectric housing mounting a plurality of terminals, the housing having a front end with an opening for receiving an end of the flat cable in engagement with contact portions of the terminals; an actuator pivotally mounted relative to the housing for floating movement between a first position allowing free insertion of the flat cable into the opening and a second position biasing the cable against the terminals; and a cam surface on the actuator for abutting a counter cam surface on the housing as the actuator is rotated about a moving pivot from its first position to its second position, causing the actuator to rotate and translate relative to the housing and sandwiching the end of the flat cable between the contact portions of the terminals and the actuator.
Claim 8
Dependent Claim
44 words
The zero insertion force electrical connector of claim 5 wherein at least one of said cam surfaces has a cam profile to effect the rotational movement of the actuator about the moving pivot and the translational movement of the actuator relative to the housing.
Claim 9
Dependent Claim
36 words
The zero insertion force electrical connector of claim 6 wherein at least one of said cam surfaces has a plurality of discrete cam sections to define said cam profile to effect said pivoting and translational movements.
