Abstract
Abstract An electrical connector for mounting on the edge of a printed circuit board, the connector having a plurality of terminals which engage against electrically conductive contact fingers formed on the printed circuit board adjacent the edge thereof, and the connector being designed to clamp over an edge portion of the circuit board so as to permit a high contact pressure between the connector terminals and the circuit board fingers without requiring a high insertion force to interconnect the connector with the circuit board.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
313 words
An electrical edge connector for mounting on an edge portion of said printed circuit board or the like to clamp over such edge portion while permitting the remaining portion of the board to project from the connector, said connector comprising, in combination, an insulator housing including first and second housing sections permanently connected by hinge means along one end to permit said housing sections to be moved between an open position where an edge portion of a printed circuit board may be inserted therebetween, and a closed position where said housing sections may be brought into pressure contact with opposite sides of said printed circuit board to clamp the same therebetween, said hinge means being dimensioned to space said first and second housing sections when in closed position by an amount sufficient to accommodate therebetween said printed circuit board on which said connector is to be mounted, the ends of said first and second housing sections opposite said hinge means defining an opening therebetween when in said closed position to permit said printed circuit board to project out of said connector whereby only an edge portion of said printed circuit board is clamped between said first and second housing sections while the remainder of said printed circuit board projects clear of said connector, a plurality of conductive metal terminal members positioned in side-by-side compartments in one of said housing sections for pressure contact with electrically conductive portions formed on a side of said circuit board where the latter is clamped between said housing sections, a plurality of flexible spring-like members located in the other of said housing sections for pressure contact with the opposite side of said circuit board when the latter is clamped between said housing sections, and locking means for releasably locking said first and second housing sections in closed position clamped on said edge portion of said printed circuit board.
Claim 2
Dependent Claim
313 words
An electrical edge connector for mounting on an edge portion of said printed circuit board or the like to clamp over such edge portion while permitting the remaining portion of the board to project from the connector, said connector comprising, in combination, an insulator housing including first and second housing sections permanently connected by hinge means along one end to permit said housing sections to be moved between an open position where an edge portion of a printed circuit board may be inserted therebetween, and a closed position where said housing sections may be brought into pressure contact with opposite sides of said printed circuit board to clamp the same therebetween, said hinge means being dimensioned to space said first and second housing sections when in closed position by an amount sufficient to accommodate therebetween said printed circuit board on which said connector is to be mounted, the ends of said first and second housing sections opposite said hinge means defining an opening therebetween when in said closed position to permit said printed circuit board to project out of said connector whereby only an edge portion of said printed circuit board is clamped between said first and second housing sections while the remainder of said printed circuit board projects clear of said connector, a plurality of conductive metal terminal members positioned in side-by-side compartments in one of said housing sections for pressure contact with electrically conductive portions formed on a side of said circuit board where the latter is clamped between said housing sections, a plurality of flexible spring-like members located in the other of said housing sections for pressure contact with the opposite side of said circuit board when the latter is clamped between said housing sections, and locking means for releasably locking said first and second housing sections in closed position clamped on said edge portion of said printed circuit board.
Claim 3
Dependent Claim
45 words
An electrical connector as defined in claim 1 where a plurality of said conductive metal terminal members are positioned in side-by-side compartments in each of said first and second housing sections for pressure contact with conductive portions formed on opposite sides of a circuit board.
Claim 4
Dependent Claim
68 words
An electrical connector as defined in claim 1 where said plurality of conductive metal terminal members are positioned in side-by-side compartments in said first housing section, and said spring-like members are provided in said second housing section for bearing against an adjacent side of a circuit board clamped in said housing and biasing the circuit board into pressure engagement with the terminals positioned in said first housing section.
Claim 5
Dependent Claim
25 words
An electrical connector as defined in claim 3 where said spring-like members are in side-by-side spaced relation along the length of said second housing section.
Claim 6
Dependent Claim
45 words
An electrical connector as defined in claim 3 where said second housing section is made of plastic, and said spring-lke members comprise a plurality of individual plastic spring members made integral with said second housing section and arranged in side-by-side relation along the length thereof.
Claim 7
Dependent Claim
51 words
An electrical connector as defined in claim 5 where said second housing section is provided with substantially one integral plastic spring member for each of the terminal compartments in said first housing section, each of said integral plastic spring members being substantially aligned with a corresponding one of said terminal compartments.
Claim 8
Dependent Claim
44 words
An electrical connector as defined in claim 1 where said first and second housing sections are made of plastic and are hingedly connected by an integral plastic hinge sufficiently flexible to permit said housing sections to be opened and closed relative to one another.
Claim 9
Dependent Claim
32 words
An electrical connector as defined in claim 1 where said first and second housing sections are hingedly connected by a hinge pin which passes through portions of each of said housing sections.
Claim 10
Dependent Claim
39 words
An electrical connector as defined in claim 8 where said first and second housing sections each have a plurality of parallel integral arms, the arms of said first and second housing sections being interconnected by a common hinge pin.
Claim 11
Dependent Claim
57 words
An electrical connector as defined in claim 1 where said locking means comprises a plurality of locking legs formed on one of said housing sections which extend into locked positions through openings formed in the other of said housing sections when said housing sections are in closed position clamped on an edge portion of a circuit board.
Claim 12
Dependent Claim
55 words
An electrical connector as defined in claim 1 where said locking means comprises a plurality of locking legs formed on one of said housing sections which hook over projecting members formed on the other of said housing sections when said housing sections are in closed position clamped on an edge portion of a circuit board.
