Abstract
Abstract An electrical connector 1 of controlled impedance includes a housing 2 on which are mounted consecutive signal transmission line pairs 12 in consecutive reverse order, each signal transmission line pair 12 being provided by a pair 7 of signal contacts 8 in one contact row 6 opposing a ground contact 9 in another contact row 6, and by having the consecutive signal transmission line pairs 12 in reverse order, the signal contacts 8 of each signal transmission line pair 12 are arranged consecutively with an adjacent ground contact 9 of another signal transmission line pair 12 of reversed order, which minimizes cross talk between different pairs 7 of signal contacts 8, and which provides maximized areas surrounding the signal contacts 8 and the ground contacts 9 for routing circuit paths.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
125 words
An electrical connector comprising: a housing which holds signal contacts and ground contacts that are arranged in at least two rows, each of the rows including at least a pair of adjacent said signal contacts and one of said ground contacts, wherein each said pair of adjacent said signal contacts in one of said rows is opposed to a respective said ground contact in another of said rows to form a signal transmission line pair, the signal transmission line pairs being arranged consecutively along the rows in an alternating inverted sequence such that, within each said row, said pair of adjacent said signal contacts of one said signal transmission line pair is adjacent to said ground contact of a different said signal transmission line pair.
Claim 2
Dependent Claim
125 words
An electrical connector comprising: a housing which holds signal contacts and ground contacts that are arranged in at least two rows, each of the rows including at least a pair of adjacent said signal contacts and one of said ground contacts, wherein each said pair of adjacent said signal contacts in one of said rows is opposed to a respective said ground contact in another of said rows to form a signal transmission line pair, the signal transmission line pairs being arranged consecutively along the rows in an alternating inverted sequence such that, within each said row, said pair of adjacent said signal contacts of one said signal transmission line pair is adjacent to said ground contact of a different said signal transmission line pair.
Claim 3
Dependent Claim
39 words
The electrical connector as recited in claim 1 , wherein each said ground contact has thereon a pair of ground contact portions which are opposed to said pair of adjacent said signal contacts of said signal transmission line pair.
Claim 4
Dependent Claim
44 words
The electrical connector as recited in claim 1 wherein the signal contacts include respective signal pin terminals extending in two signal pin rows, and the ground contacts include respective ground pin terminals extending in a ground pin row between the two signal pin rows.
Claim 5
Dependent Claim
33 words
The electrical connector as recited in claim 3 , and further comprising an insulating pin spacer having an insulating rib extending between the ground pin row and one of the signal pin rows.
Claim 6
Dependent Claim
43 words
The electrical connector as recited in claim 1 wherein, for each said signal transmission line pair, said pair of adjacent said signal contacts and said ground contact include respective terminal portions that are arranged to project at apices of a triangular shaped pattern.
Claim 7
Dependent Claim
38 words
The electrical connector as recited in claim 5 wherein the triangular shaped pattern for a consecutive said signal transmission line pair is inverted with respect to the triangular shaped pattern for a previous said signal transmission line pair.
Claim 8
Dependent Claim
23 words
The electrical connector as recited in claim 1 wherein said at least two rows are on opposite sides of an intervening connector-mating portion.
Claim 9
Dependent Claim
123 words
An electrical connector comprising: a housing, two contact rows on respective opposite sides of an intervening mating portion of the housing, each of the two contact rows including signal contacts and ground contacts, each said ground contact in one of the two contact rows opposing a respective pair of adjacent said signal contacts in the other of the two contact rows to provide signal transmission line pairs of controlled characteristic impedance, the pairs of signal contacts in the two contact rows having respective pairs of signal terminals arranged in two nonintersecting signal terminal rows, and the ground contacts in the two contact rows having respective ground terminals arranged in an intervening ground terminal row that is disposed between the two signal terminal rows.
Claim 10
Dependent Claim
123 words
An electrical connector comprising: a housing, two contact rows on respective opposite sides of an intervening mating portion of the housing, each of the two contact rows including signal contacts and ground contacts, each said ground contact in one of the two contact rows opposing a respective pair of adjacent said signal contacts in the other of the two contact rows to provide signal transmission line pairs of controlled characteristic impedance, the pairs of signal contacts in the two contact rows having respective pairs of signal terminals arranged in two nonintersecting signal terminal rows, and the ground contacts in the two contact rows having respective ground terminals arranged in an intervening ground terminal row that is disposed between the two signal terminal rows.
Claim 11
Dependent Claim
38 words
The electrical connector as recited in claim 8 wherein each said ground contact has thereon a pair of ground contact portions which are opposed to said pair of adjacent said signal contacts of said signal transmission line pair.
Claim 12
Dependent Claim
43 words
The electrical connector as recited in claim 8 wherein, for each said signal transmission line pair, said pair of adjacent said signal contacts and said ground contact include respective terminal portions that are arranged to project at apices of a triangular shaped pattern.
Claim 13
Dependent Claim
38 words
The electrical connector as recited in claim 10 wherein the triangular shaped pattern for a consecutive said signal transmission line pair is inverted with respect to the triangular shaped pattern for a previous said signal transmission line pair.
Claim 14
Dependent Claim
33 words
The electrical connector as recited in claim 8 , and further comprising an insulating pin spacer having an insulating rib extending between the ground terminal row and one of the signal terminal rows.
