Abstract
Abstract A flexible board electrical connector includes a housing having an opening on an upper corner and a plurality of contact channels on the opening; a plurality of contact elements fitted in the contact channels such that spring contact portions thereof exposed in the opening; a pressure member attached to the housing for rotation between a closed position where it is brought into contact with the contact elements and an open position where it is apart from the contact elements; and a pressure edge provided on the pressure member at such a position that when the pressure member is in the open position, it is in a first position outside from a line including the turning center of the pressure member and the contact portion of a contact element and when the pressure member is turned to the closed position, it is moved to a second position inside from the line so that once the pressure member is turned to the closed position, the pressure member is urged to the closed position by reactive forces of the contact portions and the flexible board.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
184 words
A flexible board electrical connector comprising: a substantially rectangular housing having an opening on an upper corner, a pair of support members on opposite sides of said opening, and a plurality of support channels between said support members; a plurality of contact elements fitted in said supported channels in said opening such that spring contact portions thereof are exposed in said opening; a pressure member supported by said support member for rotation about a turning center between a closed position where it is brought into a vicinity of said contact elements and an open position where it is apart from said contact elements; a pressure edge provided on said pressure member at a such position that when said pressure member is in said open position, it is in a first position outside from a line including said turning center of said pressure member and said contact portions of contact elements and when said pressure member is turned to said closed position, it is moved to a second position inside from said line such that it presses downwardly a flexible board against said contact elements.
Claim 2
Dependent Claim
184 words
A flexible board electrical connector comprising: a substantially rectangular housing having an opening on an upper corner, a pair of support members on opposite sides of said opening, and a plurality of support channels between said support members; a plurality of contact elements fitted in said supported channels in said opening such that spring contact portions thereof are exposed in said opening; a pressure member supported by said support member for rotation about a turning center between a closed position where it is brought into a vicinity of said contact elements and an open position where it is apart from said contact elements; a pressure edge provided on said pressure member at a such position that when said pressure member is in said open position, it is in a first position outside from a line including said turning center of said pressure member and said contact portions of contact elements and when said pressure member is turned to said closed position, it is moved to a second position inside from said line such that it presses downwardly a flexible board against said contact elements.
Claim 3
Dependent Claim
32 words
The flexible board electrical connector of claim 1, wherein said contact elements are provided with a fulcrum portion to be fitted in said support channels, about which said pressure member is turned.
Claim 4
Dependent Claim
28 words
The flexible board electrical connector of claim 1, wherein said pressure edge is formed with a pair of adjoining flat surfaces having different distances from said turning center.
Claim 5
Dependent Claim
83 words
The flexible board electrical connector of claim 1, which further comprising a plurality of support portions provided on said housing at a position more interior to said contact portions of said contact elements to support a front portion of said flexible board so that when said pressure member is turned to said closed position, said support portions and said contact portions support said flexible board while said pressure member exerts a pressure on a point between said support portions and said contact portions.
Claim 6
Dependent Claim
27 words
The flexible board electrical connector of claim 4, wherein said contact elements have a flat shape with a fulcrum portion to be fitted into said support channel.
Claim 7
Dependent Claim
26 words
The flexible board electrical connector of claim 5, wherein said fulcrum portion has a turning surface interior to said turning center for supporting said pressure members.
Claim 8
Dependent Claim
81 words
The flexible board electrical connector of claim 1, which further comprising an abutting section provided on said pressure member on a side opposite to said pressure edge for abutting said housing at a predetermined angle when said pressure member is turned to said open position, said abutting section being disposed such a position that an abutting location between said abutting section and said housing is increasingly away from said fulcrum portion with an increasing angle of rotation of said pressure member.
Claim 9
Dependent Claim
56 words
The flexible board electrical connector of claim 7, wherein said pressure member is provided with a bearing groove which comes off from said housing when said abutting section abuts said housing while said support members undergoes elastic deformation by turning of said pressure member thereby allowing a shift of said turning center of said pressure member.
