Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
164 words
A printed circuit board connector comprising: an insulated housing member having a bottom, a pair of spaced side walls extending upwardly from said bottom and plurality of contact chambers formed along at least one of said side walls above said bottom; a slot in said housing member between said side walls communicating with said contact chambers and adapted to slidably receive a printed circuit board therein; a longitudinally extending bridge member in each of said contact chambers, said bridge member in each said chamber being spaced from said one side wall and said bottom and defining a first upwardly extending opening and a second opening extending away from said bottom and bounded by said one side wall and said bridge member extending inwardly toward said slot from said one side wall and bounded by said bottom and said bridge member; and a plurality of contact receiving holes in said bottom located on the side of said bridge member opposite to said one side wall.
Claim 2
Dependent Claim
164 words
A printed circuit board connector comprising: an insulated housing member having a bottom, a pair of spaced side walls extending upwardly from said bottom and plurality of contact chambers formed along at least one of said side walls above said bottom; a slot in said housing member between said side walls communicating with said contact chambers and adapted to slidably receive a printed circuit board therein; a longitudinally extending bridge member in each of said contact chambers, said bridge member in each said chamber being spaced from said one side wall and said bottom and defining a first upwardly extending opening and a second opening extending away from said bottom and bounded by said one side wall and said bridge member extending inwardly toward said slot from said one side wall and bounded by said bottom and said bridge member; and a plurality of contact receiving holes in said bottom located on the side of said bridge member opposite to said one side wall.
Claim 3
Dependent Claim
66 words
A connector as set forth in claim 1 including a contact element in each of said chambers, each said contact element having a retention tongue, a terminal end and a contacting portion, said terminal end being mounted in one of said holes, said retention tongue Extending into said second opening and said contacting portion extending into said slot for contact with a printed circuit board therein.
Claim 4
Dependent Claim
29 words
A connector as set forth in claim 2 wherein said contacting portion and said tongue of each said contact element bifurcate from said terminal end thereof in different directions.
Claim 5
Dependent Claim
29 words
A connector as set forth in claim 2 wherein the upper end of the contact portion of each of said contact elements is reversely bent to form a hook.
Claim 6
Dependent Claim
26 words
A connector as set forth in claim 4 wherein the contacting portion of each said contact element is divided by a slot into two spring legs.
Claim 7
Dependent Claim
23 words
A connector as set forth in claim 1 including: lateral openings extending through said one side wall in alignment with said second openings.
Claim 8
Dependent Claim
59 words
A connector as set forth in claim 1 including: a plurality of second contact chambers formed along the other of said side walls each provided with one of said bridge members; and a plurality of second contact receiving holes in said bottom located on the side of said second contact chamber bridge members opposite to said other side wall.
