Abstract
Abstract A connector for circuit boards is disclosed, comprising a flat conductor cable of flexible, nonconductive backing material having opposite major sides on which are disposed patterns of exposed electrical conductors. Means, preferably notches, are provided on the cable for providing registry between desired conductors on the cable and a circuit board or a plurality of circuit boards when the cable is assembled therewith. The described conductor cable provides a simplified means for electrically joining a plurality of similar circuit boards. There is also disclosed a method of joining a cable according to the invention with a printed circuit board.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
254 words
An electrical connection comprising, in combination, a circuit board having opposite major sides with first and second patterns of electrical conductors respectively on said major sides, said circuit board having therein an indented portion located centrally of an edge thereof and said conductor members each having portions terminating in said indented portion in said edge, a flat conductor cable of flexible nonconductive backing material having opposite major sides on which are disposed patterns of exposed electrical conductors respectively on said major sides, said cable adjacent one end thereof having an opposed pair of guide notches extending inwardly transversely from the side edges thereof, said one end of the cable being folded upon itself such that exposed conductors on one of said major sides face each other on opposite sides of the fold, a yieldable piece of insulating material disposed between the inner facing surfaces of said folded end of said cable, the portion of said cable between said notches being disposed within said indented portion of said circuit board with the notches of said cable being received by portions of said circuit board adjacent to said indented portion, and means for securing said cable to said circuit board such that the conductors on said one major side of said cable are in electrical contact with the conductors on one of said major sides of said circuit board and the conductors on said opposite major side of said cable are in electrical contact with the conductors on the opposite major side of said circuit board.
Claim 2
Dependent Claim
254 words
An electrical connection comprising, in combination, a circuit board having opposite major sides with first and second patterns of electrical conductors respectively on said major sides, said circuit board having therein an indented portion located centrally of an edge thereof and said conductor members each having portions terminating in said indented portion in said edge, a flat conductor cable of flexible nonconductive backing material having opposite major sides on which are disposed patterns of exposed electrical conductors respectively on said major sides, said cable adjacent one end thereof having an opposed pair of guide notches extending inwardly transversely from the side edges thereof, said one end of the cable being folded upon itself such that exposed conductors on one of said major sides face each other on opposite sides of the fold, a yieldable piece of insulating material disposed between the inner facing surfaces of said folded end of said cable, the portion of said cable between said notches being disposed within said indented portion of said circuit board with the notches of said cable being received by portions of said circuit board adjacent to said indented portion, and means for securing said cable to said circuit board such that the conductors on said one major side of said cable are in electrical contact with the conductors on one of said major sides of said circuit board and the conductors on said opposite major side of said cable are in electrical contact with the conductors on the opposite major side of said circuit board.
Claim 3
Dependent Claim
49 words
An electrical connection as defined in claim 1, wherein said means for securing said cable to said circuit board comprises a place clamp which comprises a strip of flexible insulating material of U-shaped configuration and a spring of U-shaped configuration in embracing relation with said strip of insulating material.
Claim 4
Dependent Claim
236 words
In combination, a circuit board of the type comprising a sheet of insulating material having opposite major sides with first and second patterns of electrical conductors respectively on said major sides, a flat conductor cable of flexible nonconductive backing material having opposite major sides on which are exposed patterns of electrical conductors, at least one end of said conductor cable being folded upon itself and about said circuit board such that conductors on a first major side of the circuit board will contact conductors on a first major side of said conductor cable while conductors on the second major side of the circuit board will contact conductors on a second major side of said conductor cable, the folded end of said cable having a first portion in abutment with said first major side of the circuit board whereby conductors on said first major side of the circuit board are in contact with conductors on said first major side of the conductor cable, a second portion reversely bent with respect to said first portion to form a U-shaped cross-sectional configuration, a third portion bent at right angles to said second portion and extending past the edge of said circuit board, and a fourth portion bent at right angles to said third portion with conductors on the second major side of said fourth portion being on contact with conductors on the second major side of said circuit board.
Claim 5
Dependent Claim
236 words
In combination, a circuit board of the type comprising a sheet of insulating material having opposite major sides with first and second patterns of electrical conductors respectively on said major sides, a flat conductor cable of flexible nonconductive backing material having opposite major sides on which are exposed patterns of electrical conductors, at least one end of said conductor cable being folded upon itself and about said circuit board such that conductors on a first major side of the circuit board will contact conductors on a first major side of said conductor cable while conductors on the second major side of the circuit board will contact conductors on a second major side of said conductor cable, the folded end of said cable having a first portion in abutment with said first major side of the circuit board whereby conductors on said first major side of the circuit board are in contact with conductors on said first major side of the conductor cable, a second portion reversely bent with respect to said first portion to form a U-shaped cross-sectional configuration, a third portion bent at right angles to said second portion and extending past the edge of said circuit board, and a fourth portion bent at right angles to said third portion with conductors on the second major side of said fourth portion being on contact with conductors on the second major side of said circuit board.
Claim 6
Dependent Claim
29 words
The combination of claim 3 including a yieldable piece of insulating material disposed between the inner facing surfaces of the first and second portions of said U-shaped cross-sectional configuration.
Claim 7
Dependent Claim
85 words
The combination of claim 3 wherein said circuit board is provided with an indented portion located in an edge thereof, said folDed end of the cable being received within said indented portion, the third portion of said cable which extends past the edge of said circuit board having notches in the opposite edges thereof which receive the edges of said indented portion, the notches in the cable in said indented portion providing registry between the conductors on said circuit board and conductors on said cable.
Claim 8
Dependent Claim
50 words
The combination of claim 3 including a generally U-shaped clamp inserted over said folded end of said cable and having a first leg portion which engages said second portion of the folded end of said cable and a second leg portion which engages said fourth portion of the folded end.
