Abstract
Abstract Cross-talk in RJ 45 type connectors can be reduced by twisting individual wires of a conductor pair with wires of another conductor pair. Alternate pairs may be twisted clockwise and counter clockwise and at least one further twisted pair may be formed from a wire of each of two twisted pairs. The wires may then be braided in their original conductor pair configurations. <IMAGE>

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
61 words
A telecommunications connector comprising a wire carrier having a plurality of contact wires and a plurality of insulated wires each connected to a respective contact wire and forming at least three conductor pairs, wherein an insulated wire of a conductor pair is twisted or crossed with an insulated wire of another conductor pair to form a twisted or crossed wire pair.
Claim 2
Dependent Claim
33 words
A telecommunications connector according to claim 1, wherein an insulated wire of each conductor pair is twisted with an insulated wire of another conductor pair to form a least three twisted wire pairs.
Claim 3
Dependent Claim
15 words
A telecommunications connector according to claim 2, wherein each twisted pair comprises two wire twists.
Claim 4
Dependent Claim
23 words
A telecommunications connector according to claim 2 or 3, wherein the twisted pairs are twisted alternatively in a clockwise and counter clockwise direction.
Claim 5
Dependent Claim
31 words
A telecommunications connector according to claim 2, 3 or 4, wherein an insulated wire of at least one twisted pair is further twisted with an insulated wire of another twisted pair.
Claim 6
Dependent Claim
135 words
A telecommunications connector according to any of claims 1 to 5, comprising eight insulated wires divided into four conductor pairs, wherein a first wire of the first conductor pair is twisted in a counter clockwise sense with a first wire of the second pair, to form a first twisted pair, a second wire of the first pair is twisted with a first wire of the fourth pair in a clockwise sense to form a second twisted pair, a second wire of the second conductor pair is twisted with a first wire of the third conductor pair in a clockwise sense to form a third twisted pair, and the second wire of the fourth pair is twisted in a counter clockwise sense with the second wire of the fourth pair to form a further twisted pair.
Claim 7
Dependent Claim
33 words
A telecommunications connector according to claim 6, wherein a first wire of the fourth twisted pair is twisted with a first wire of the second twisted pair to form a fourth twisted pair.
Claim 8
Dependent Claim
28 words
A telecommunications connector according to claim 6 or 7, wherein each wire of each twisted pair is braided with the wire with which it formed a conductor pair.
Claim 9
Dependent Claim
102 words
A telecommunications connector according to claim 6, 7 or 8, wherein the fourth and fifth insulated wires for the first conductor pair, the first and second insulated wires form the second conductor pair, the third and sixth insulated wires form the third conductor pair and the seventh and eighth wires form the fourth conductor pair, and wherein the fifth and second insulated wires form the first twisted pair, the fourth and seventh insulated wires form the second twisted pair, the first and third insulated wires form the third twisted pair, and the sixth and eighth insulated wires form the fourth twisted pair.
Claim 10
Dependent Claim
19 words
A telecommunications connector according to claim 9, wherein the fourth and sixth insulated wires form the further twisted pair.
Claim 11
Dependent Claim
23 words
A telecommunications connector according to claim 1, 2, 6 or 7, wherein the number of twists in each twisted pair is not equal.
Claim 12
Dependent Claim
113 words
A telecommunications connector according to claim 6, wherein a second wire of the second twisted pair is twisted with a second wire of the fourth twisted pair to form a second further twisted pair, a first wire of the first twisted pair is twisted with a first wire of the third twisted pair to form a third further twisted pair, a second wire of the third twisted pair is twisted with a first wire of the further twisted pair to form a fourth further twisted pair and the second wire of the first twisted pair is twisted with the second wire of the further twisted pair to form a fifth further twisted pair.
