Abstract
Abstract A faceplate assembly is provided for use in printed circuit board assemblies comprising a printed circuit board with electrical contact surfaces, and a housing frame with slotted guide rails to receive the circuit board, and edge connector means fastened to the housing frame and displaced at the end of the guide rails. The faceplate assembly includes insertion, extraction and positive latching means molded as an integral part of the faceplate. The faceplate body extends substantially the entire length of the printed circuit board edge and is pivotally mounted to the printed circuit board near one corner thereof. The insertion/extraction means, located on the pivotal end of the faceplate body, is actuated by manual pivotal movement of the faceplate thereby causing the insertion/extraction means to coact with a housing frame U-channel to thus effect engagement or disengagement of the printed circuit board electrical contacts to or from the housing frame edge connector contacts. Final pivotal movement of the faceplate body, directed toward the printed circuit board edge to effect engagement of the corresponding electrical contacts, activates the positive latching means located on the faceplate at the end opposite the insertion/extraction means to thereby positively lock the board and housing frame electrical contacts into a mated position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
174 words
A latching faceplate assembly for use in combination with each of a plurality of spaced apart printed circuit boards and a housing into which said boards are inserted, said assembly comprising: a channel formed along a frontal edge of the housing transverse to the boards contained within said housing, and a planar member for each board which extends substantially the entire length of the frontal edge thereof and projecting laterally from said frontal edge an amount sufficient to fill the interboard spacing so as to essentially close the housing frontal opening thereby protecting the housing contents, said planar member being pivotally mounted at one end thereof to a corner of said board, said planar member having an extended portion at its pivotal end which engages said channel so as to exert a lateral force on said board to aid board insertion into said housing when said planar member is pivoted toward the board edge and so that an opposite lateral force is exerted to aid extraction when said planar member is pivoted away therefrom.
Claim 2
Dependent Claim
174 words
A latching faceplate assembly for use in combination with each of a plurality of spaced apart printed circuit boards and a housing into which said boards are inserted, said assembly comprising: a channel formed along a frontal edge of the housing transverse to the boards contained within said housing, and a planar member for each board which extends substantially the entire length of the frontal edge thereof and projecting laterally from said frontal edge an amount sufficient to fill the interboard spacing so as to essentially close the housing frontal opening thereby protecting the housing contents, said planar member being pivotally mounted at one end thereof to a corner of said board, said planar member having an extended portion at its pivotal end which engages said channel so as to exert a lateral force on said board to aid board insertion into said housing when said planar member is pivoted toward the board edge and so that an opposite lateral force is exerted to aid extraction when said planar member is pivoted away therefrom.
Claim 3
Dependent Claim
39 words
The faceplate assembly of claim 1 wherein said channel is comprised of a U-channel and the planar member pivotal movement causes said extended portions to coact with the inner surfaces of said U-channel to thereby effect lateral board movement.
Claim 4
Dependent Claim
39 words
The faceplate assembly of claim 1 wherein said channel is comprised of a U-channel and the planar member pivotal movement causes said extended portions to coact with the outer surfaces of said U-channel to thereby effect lateral board movement.
Claim 5
Dependent Claim
19 words
The faceplate assembly of claim 2 or 3 wherein said extended portions comprise two similarly-shaped members straddling said board.
Claim 6
Dependent Claim
45 words
The faceplate assembly of claim 1 wherein said planar member includes latching means on the end opposite said pivotal end, said latching means being responsive to planar member pivotal movement toward said board edge for locking said board in an engaged position within said housing.
Claim 7
Dependent Claim
45 words
The faceplate assembly of claim 5 wherein in the locked position, a portion of said latching means straddles said board and the contiguous areas of said board and latching means include complementary surfaces frictionally mating so that said planar member is locked to said board.
Claim 8
Dependent Claim
26 words
The faceplate assembly of claim 6 wherein the latching means complementary surface comprises a convex-shaped surface and the board complementary surface comprises a complementary sized hole.
Claim 9
Dependent Claim
44 words
The faceplate assembly of claim 5 above in said extended portion aiding insertion and extraction and said latching means are formed as an integral part of the planar member thereby allowing a single pivotal movement to effect unlatching and extraction or insertion and latching.
Claim 10
Dependent Claim
36 words
The faceplate assembly of claim 8 wherein said extended portion, the planar member and the latching means are molded as an integral unit out of plastic so that the manufacture thereof is effected in one operation.
Claim 11
Dependent Claim
63 words
The faceplate assembly of claim 5 wherein the pivotal end of said planar member is pivotal about the top corner of said board so that the mass of said planar member defines a cantilevered weight which when acted upon by gravity exerts a continuous lateral force upon said board in a direction to resist extraction when said board is engaged yet not latched.
