Low crosstalk card edge connector

An electrical connector, comprising:

• an insulative housing, the insulative housing comprising at least one opening;
• and
• a plurality of conductors held by the housing, each of the plurality of conductors comprising a tip portion, a tail portion, a contact portion disposed between the tail portion and the tip portion, and a body portion disposed between the tail portion and the contact portion;
• wherein:
• the tail portions of the plurality of conductors extend from the housing;
• the contact portions of the plurality of conductors are exposed within the at least one opening;
• the body portions of the plurality of conductors have a first thickness;
• and
• the tip portions of the plurality of conductors have a second thickness, less than the first thickness.

An electrical connector, comprising:

• an insulative housing, the insulative housing comprising at least one opening;
• a plurality of conductors held by the housing, each of the plurality of conductors comprising a tip portion, a tail portion, a contact portion disposed between the tail portion and the tip portion, and a body portion disposed between the tail portion and the contact portion;
• wherein:
• the plurality of conductors are arranged in a row with a uniform pitch between tip portions and tail portions;
• the plurality of conductors comprise a plurality of groups of at least three conductors, each group comprising a first conductor, a second conductor and a third conductor;
• the plurality of conductors comprise a first region in which:
• the body portions of the first conductor and the second conductor of each group of the plurality of groups has the same first width;
• the third conductor of the group has a second width, greater than the first width, and
• the edge to edge separation between the first conductor and the second conductor and between the second conductor and the third conductor is the same.

An electrical connector, comprising:

• an insulative housing comprising a slot;
• a plurality of conductors, each of the plurality of conductors comprising a tip portion, a tail portion, a contact portion disposed between the tail portion and the tip portion, and a body portion disposed between the tail portion and the contact portion, the plurality of conductors comprising a plurality of groups of three conductors, each group of the plurality of groups comprising a first and second conductors having a first maximum width and a third conductor having a second maximum width that is greater than the first maximum width;
• and
• an overmolding in physical contact with the body portion of each of the plurality of conductors;
• wherein:
• the body portions of the plurality of conductors are disposed within the housing with tip portions exposed in the slot;
• the first conductor has a first shape;
• the second conductor has a second shape;
• and
• the third signal conductor has a third shape different from the first shape and the second shape;
• and
• the second shape is a mirror image of the first shape.
