Abstract
Abstract An electrical connector assembly (10) comprises first and second electrical connectors (12 and 14) and/or a printed wiring board (70) having electrical conductors thereon ending in termini (32, 34). Dimples (36, 38 and/or 72) are provided on the termini and provide connections between the flex cables or a flex cable and the printed wiring board. The dimples also provide self-alignment between the matable electrical connectors.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
130 words
An electrical connector assembly comprising: a plurality of electrical connectors, each including matable surfaces and a plurality of electrical conductors having termini terminating respectively on said surfaces; dimples on said conductor termini and respectively configured with matable surfaces of concave and convex configurations to provide conforming concave-convex contacts with one another for electrically coupling said electrical conductors respectively of said electrical connectors, wherein said dimples on mating ones of said conductors on said connectors are paired in contact with one another for effecting a self-alignment of said conductors; and a plate extending over said dimples on a first of said connectors and means associated with a second of said connectors and mechanically coupled to said plate for securing said connectors together and for maintaining the contact between said mating dimples.
Claim 2
Dependent Claim
130 words
An electrical connector assembly comprising: a plurality of electrical connectors, each including matable surfaces and a plurality of electrical conductors having termini terminating respectively on said surfaces; dimples on said conductor termini and respectively configured with matable surfaces of concave and convex configurations to provide conforming concave-convex contacts with one another for electrically coupling said electrical conductors respectively of said electrical connectors, wherein said dimples on mating ones of said conductors on said connectors are paired in contact with one another for effecting a self-alignment of said conductors; and a plate extending over said dimples on a first of said connectors and means associated with a second of said connectors and mechanically coupled to said plate for securing said connectors together and for maintaining the contact between said mating dimples.
Claim 3
Dependent Claim
37 words
An electrical connector according to claim 3 in which said electrical connectors comprise a pair of flexible flat cables and each of said dimples on each of said cables comprises a depression having concave and convex surfaces.
Claim 4
Dependent Claim
49 words
An electrical connector according to claim 3 in which a first of said electrical connectors comprises a flexible flat cable whose dimples comprise depressions having concave and convex surfaces, and a second of said electrical connectors comprises a rigid printed wiring board whose dimples comprise pads having convex surfaces.
Claim 5
Dependent Claim
59 words
An electrical connector according to claim 1 wherein said plate includes a pair of relatively thicker end portions and a thinner intermediary portion for defining a recess extending over and into contact with said dimples on said first connector, for urging said first connector dimples into the contact with said second connector dimples and for maintaining the contact therebetween.
Claim 6
Dependent Claim
44 words
An electrical connector according to claim 4 in which said plate is formed from a resilient material and is curved to provide a convex side facing said first connector dimples for ensuring complete and uniform contact therewith and uniform engagement between said mating dimples.
Claim 7
Dependent Claim
33 words
An electrical connector according to claim 4 in which said thicker and thinner portions are so dimensioned as to provide a space for protecting said dimples from being stressed beyond their elastic limit.
Claim 8
Dependent Claim
40 words
An electrical connector according to claim 4 further comprising a resilient pad positioned between said intermediary portion and said first connector dimples for exerting a resilient bias thereagainst and for protecting said dimples from being stressed beyond their elastic limit.
Claim 9
Independent Claim
143 words
A method for forming an electrical connector assembly between a plurality of electrical connectors, each having matable surfaces and a plurality of electrical conductors having termini terminating respectively on the surfaces, comprising the steps of: providing the conductor termini with dimples; and configuring the dimples with mating concave-convex surfaces in contact with one another and pairing the dimples on mating ones of the conductors on the first and second connectors for electrically coupling the electrical conductors respectively of the electrical connectors and enabling self-alignment among the conductors; and utilizing a curved plate of resilient material having concave and convex sides, positioning the convex side of the curved plate against the dimples of one of the connectors when fastening the connectors together, and flattening the plate against the one conductor for ensuring complete and uniform contact therewith and uniform engagement between the mating dimples.
Claim 10
Independent Claim
143 words
A method for forming an electrical connector assembly between a plurality of electrical connectors, each having matable surfaces and a plurality of electrical conductors having termini terminating respectively on the surfaces, comprising the steps of: providing the conductor termini with dimples; and configuring the dimples with mating concave-convex surfaces in contact with one another and pairing the dimples on mating ones of the conductors on the first and second connectors for electrically coupling the electrical conductors respectively of the electrical connectors and enabling self-alignment among the conductors; and utilizing a curved plate of resilient material having concave and convex sides, positioning the convex side of the curved plate against the dimples of one of the connectors when fastening the connectors together, and flattening the plate against the one conductor for ensuring complete and uniform contact therewith and uniform engagement between the mating dimples.
Claim 11
Dependent Claim
22 words
A method according to claim 8 further comprising the step of providing a recess in the plate for receiving the conductors therein.
