Abstract
Abstract An electrical connector for FPC comprises a dielectric housing, a plurality of contacts received in the housing, and an actuation portion movably mounted on the housing. The housing defines a longitudinal receiving portion, and the receiving portion has a plurality of protrusions. The contact is formed with a first arm, a second arm and a foot, and an end of the first arm defines a head. The protrusions are formed adjacent to the head, and the profile of the head has a common axis with the profiles of its adjacent protrusions. The head together with the protrusions serves as a common shaft for the actuation portion.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
140 words
An electrical connector for connecting a flexible printed circuit to a printed circuit board, comprising: a dielectric housing having a longitudinal receiving portion, the receiving portion defining a plurality of passageways and protrusions; a plurality of contacts received in the housing, the contact defining a first arm, a second arm opposed to the first arm and a foot, the first arm defining a head at its distal end; an actuation portion movably mounted on the housing, the actuation portion defining an elongated base and a recess for mating with the head and the respective protrusion; wherein the protrusion is formed adjacent to the head, a profile of the head has a common axis with a profile of the protrusion, and the head and the protrusion serve as a common shaft for the actuation portion to pivot about the common axis.
Claim 2
Dependent Claim
140 words
An electrical connector for connecting a flexible printed circuit to a printed circuit board, comprising: a dielectric housing having a longitudinal receiving portion, the receiving portion defining a plurality of passageways and protrusions; a plurality of contacts received in the housing, the contact defining a first arm, a second arm opposed to the first arm and a foot, the first arm defining a head at its distal end; an actuation portion movably mounted on the housing, the actuation portion defining an elongated base and a recess for mating with the head and the respective protrusion; wherein the protrusion is formed adjacent to the head, a profile of the head has a common axis with a profile of the protrusion, and the head and the protrusion serve as a common shaft for the actuation portion to pivot about the common axis.
Claim 3
Dependent Claim
39 words
The electrical connector as claimed in claim 1 , wherein a distance from the profile of the protrusion to the printed circuit board is greater than a distance from the profile of the head to the printed circuit board.
Claim 4
Dependent Claim
24 words
The electrical connector as claimed in claim 1 , wherein the contact comprises a middle portion connecting the first arm and the second arm.
Claim 5
Dependent Claim
27 words

Claim 6
Dependent Claim
20 words
The electrical connector as claimed in claim 4 , wherein the head and the protrusion are formed into round shape.
Claim 7
Dependent Claim
30 words
The electrical connector as claimed in claim 5 , wherein the housing defines a holding portion and a pair of retention arms extending from both ends of the receiving portion.
Claim 8
Dependent Claim
25 words
The electrical connector as claimed in claim 6 , wherein the actuation portion defines two side walls respectively formed at each end of the base.
Claim 9
Dependent Claim
25 words
The electrical connector as claimed in claim 7 , wherein the retention arm defines a pair of receiving recesses in both ends of the housing.
Claim 10
Dependent Claim
32 words
The electrical connector as claimed in claim 8 , wherein the receiving recess defines an outside wall, and at least two guideways with blocks are formed in both ends of the housing.
Claim 11
Dependent Claim
23 words
The electrical connector as claimed in claim 9 , wherein the actuation portion defines two pivots abutting against the blocks of the guideways.
Claim 12
Dependent Claim
29 words
The electrical connector as claimed in claim 10 , wherein the pressing portion defines an upper portion, the upper surface defining a plurality of grooves corresponding to the passageways.
Claim 13
Dependent Claim
17 words
The electrical connector as claimed in claim 11 , wherein the grooves are parallel with each other.
Claim 14
Dependent Claim
23 words
The electrical connector as claimed in claim 12 , wherein the actuation portion has a pressing portion for pressing the flexible printed circuit.
Claim 15
Dependent Claim
125 words
An electrical connector assembly comprising: an insulative housing defining a receiving slot therein; a plurality of contacts disposed by upper and lower sides of the receiving slot, said contacts defining abutment ends on the upper side; a plurality of abutment protrusions formed on a front face of the housing adjacent to the neighboring abutment ends in an alternating manner; an actuator pivotally mounted to the housing; wherein the actuator defines an engagement edge which initially only engages the protrusions without engagement with the abutment ends at an initial stage when said actuator is rotated from an open position to a closed position, but successively engages the abutment ends at a final stage when said actuator is rotated from the open position to the closed position.
Claim 16
Dependent Claim
125 words
An electrical connector assembly comprising: an insulative housing defining a receiving slot therein; a plurality of contacts disposed by upper and lower sides of the receiving slot, said contacts defining abutment ends on the upper side; a plurality of abutment protrusions formed on a front face of the housing adjacent to the neighboring abutment ends in an alternating manner; an actuator pivotally mounted to the housing; wherein the actuator defines an engagement edge which initially only engages the protrusions without engagement with the abutment ends at an initial stage when said actuator is rotated from an open position to a closed position, but successively engages the abutment ends at a final stage when said actuator is rotated from the open position to the closed position.
Claim 17
Dependent Claim
20 words
The assembly as described in claim 14 , wherein said engagement edge also engages the protrusions at the final stage.
