Abstract
Abstract An electrical connector for flexible printed board ( 1 ) has a housing ( 4 ) with an opening, and a cover ( 7 ) being rotatable about a predetermined pivotal axis for opening or closing the opening. A resilient piece ( 35 ) of a fork-shaped contact ( 23 ) has a first and a second branches ( 39, 41 ) branched from a free end ( 38 ) thereof. The second branch ( 41 ) includes a contact point coming into contact with a flexible printed board ( 2 ) inserted in an insertion space ( 3 ). One edge of the cover ( 7 ) is provided with a regulating portion ( 55 ) interposed between the first and second branches ( 39, 41 ). The regulating portion ( 55 ) restricts bidirectional displacements of the free end ( 38 ) of the resilient piece ( 35 ) within a predetermined range.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
164 words
An electrical connector for a flexible printed board comprising: a synthetic-resin housing having an opening, a plurality of fork-shaped contacts being arranged to face into the opening, each of the contacts having a resilient piece and a fixing piece in opposed relation, an insertion space for the flexible printed board defined between the resilient piece and the fixing piece, and a synthetic-resin cover being rotatable around a predetermined pivotal axis to open or close the opening, wherein each fork-shaped contact includes a U-shaped portion including a first branch and a second branch branched from a free end of the resilient piece, wherein the second branch adjoins the insertion space; wherein the second branch includes a contact point pressed into contact with the flexible printed board inserted in the insertion space, and wherein one edge of the cover includes a regulating portion interposed between the first and the second branches for bidirectionally restricting a range of displacement of the free end of the resilient piece.
Claim 2
Dependent Claim
164 words
An electrical connector for a flexible printed board comprising: a synthetic-resin housing having an opening, a plurality of fork-shaped contacts being arranged to face into the opening, each of the contacts having a resilient piece and a fixing piece in opposed relation, an insertion space for the flexible printed board defined between the resilient piece and the fixing piece, and a synthetic-resin cover being rotatable around a predetermined pivotal axis to open or close the opening, wherein each fork-shaped contact includes a U-shaped portion including a first branch and a second branch branched from a free end of the resilient piece, wherein the second branch adjoins the insertion space; wherein the second branch includes a contact point pressed into contact with the flexible printed board inserted in the insertion space, and wherein one edge of the cover includes a regulating portion interposed between the first and the second branches for bidirectionally restricting a range of displacement of the free end of the resilient piece.
Claim 3
Dependent Claim
43 words
The electrical connector for flexible printed board as claimed in claim 1 , wherein the regulating portion includes a cam surface for pushing the first branch into displacement with the opening of the cover so as to expand the insertion space in conjunction.
Claim 4
Dependent Claim
31 words
The electrical connector for flexible printed board as claimed in claim 2 , wherein the cam surface moves away from the first branch in conjunction with the closing of the cover.
Claim 5
Dependent Claim
51 words
The electrical connector for flexible printed board as claimed in claim 2 , wherein the cover includes a through hole allowing the ingress or egress of the first branch thereinto or therefrom when the cover is closed or opened, a part of the through hole being defined by the cam surface.
Claim 6
Dependent Claim
54 words
The electrical connector for flexible printed board as claimed in claim 1 , wherein the regulating portion includes a recess for restricting the displacement of the second branch within a predetermined range as allowing the ingress of the second branch thereinto, when the cover is closed with a flexible printed board inserted in place.
Claim 7
Dependent Claim
39 words
The electrical connector for flexible printed board as claimed in claim 1 , wherein the regulating portion includes a bearing surface for bearing the first branch when the cover is closed without a flexible printed board inserted in place.
Claim 8
Dependent Claim
26 words
The electrical connector for flexible printed board as claimed in claim 6 , wherein a recess is formed in an opposite surface to the bearing surface.
Claim 9
Dependent Claim
24 words
The electrical connector for flexible printed board as claimed in claim 6 , wherein the bearing surface and a cam surface adjoins each other.
Claim 10
Dependent Claim
23 words
The electrical connector for flexible printed board as claimed in claim 1 , wherein the predetermined pivotal axis extends through the regulating portion.
Claim 11
Dependent Claim
49 words
The electrical connector for flexible printed board as claimed in claim 1 , wherein the cover includes a metallic wire partially embedded therein during molding thereof, and wherein a pair of pivot shafts along the predetermined pivotal axis are provided at a pair of opposite ends of the wire.
Claim 12
Dependent Claim
36 words
The electrical connector for flexible printed board as claimed in claim 10 , wherein the wire includes an intermediate portion between the pair of opposite ends thereof, the intermediate portion being substantially shaped like a channel.
Claim 13
Dependent Claim
51 words
The electrical connector for flexible printed board as claimed in claim 1 , wherein the contact point of the fork-shaped contact having the first and the second branches is located ahead of a contact point of the other fork-shaped contact with respect to an insertion direction of a flexible printed board.
