Abstract

A cable connector includes a contact assembly including an electrically insulating block body and multiple signal contacts incorporated therein; an intermediary interconnection board having multiple contact connection pads, multiple groups of wire connection pads, and multiple interconnects on its surface, the interconnects connecting the contact connection pads to the corresponding wire connection pads, the contact connection pads being electrically connected to the corresponding signal contacts of the contact assembly; and a cable having multiple wires electrically connected to the corresponding wire connection pads. Adjacent groups of the wire connection pads are offset in a direction in which the interconnects extend in a manner to reduce crosstalk.

Claims

1. A cable connector, comprising:

a contact assembly including an electrically insulating block body and a plurality of signal contacts incorporated therein;

an intermediary interconnection board having a plurality of contact connection pads, a plurality of groups of adjacent wire connection pads, and a plurality of interconnects on a surface thereof, interconnects connecting the contact connection pads to the corresponding wire connection pads, the contact connection pads being electrically connected to the corresponding signal contacts of the contact assembly; and

a cable having a plurality of wires electrically connected to the corresponding wire connection pads,

wherein adjacent ones of the groups of the adjacent wire connection pads in a direction along a first edge of the intermediary interconnection board opposed to a second edge thereof along which the contact connection pads are arranged are offset in a direction in which the interconnects extend, so that the groups of the adjacent wire connection pads are arranged at a first interval greater than a second interval at which the adjacent wire connection pads are arranged in each of the groups thereof.

2. The cable connector as claimed in claim 1, wherein the adjacent wire connection pads in each of the groups thereof are offset in the direction in which the interconnects extend.

3. The cable connector as claimed in claim 1, wherein the wire connection pads extend obliquely with respect to the direction in which the interconnects extend.

4. The cable connector as claimed in claim 3, wherein the wire connection pads extend in a plurality of directions.

5. The cable connector as claimed in claim 1, wherein a ground layer is provided at a position corresponding to the wire connection pads on a surface of the intermediary interconnection board facing away from the surface thereof on which the wire connection pads are provided.

6. The cable connector as claimed in claim 1, wherein the intermediary interconnection board includes a plurality of guide grooves on the surface thereof, the guide grooves guiding the wires of the cable.

7. The cable connector as claimed in claim 6, wherein at least one of the wires has insulating coating.
