LOW CROSSTALK INSULATION DISPLACEMENT CONNECTOR FOR TERMINATING CABLE TO CIRCUIT BOARD
First Claim
1. An electrical connector mounted to a printed circuit board comprising:
- a housing having a cable-receiving surface, a terminal surface opposite the cable-receiving surface and a board mounting surface for mounting to said printed circuit board, said housing comprising a cable-receiving groove extending thereinto from the cable-receiving surface, and a plurality of recesses extending thereinto from the terminal surface;
a cable disposed in the housing, the cable having a plurality of wires in the recesses, and a shield surrounding the wires and received in the cable-receiving groove;
a plurality of signal terminals each comprising a retention portion disposed in a corresponding recess of the housing and electrically engaging a corresponding wire by insulation displacement connection (IDC), a body portion engaging with the housing, and a tail portion for soldering to said printed circuit board; and
a plurality of grounding terminals received in the housing and arranged alternately to the signal terminals.

Abstract
An electrical connector (1) mounted to a PCB (3) comprises a bottom housing (4), an upper housing (5) assembled to the bottom housing, a cable (2), a plurality of signal terminals (6) and grounding terminals (7, 8) therein. The bottom housing has a first groove (42) and a plurality of recesses (402). The upper housing has a second groove (52) and a plurality of depressing blocks (500) being respectively aligned with the first groove and the recesses. The cable extends through a cable-receiving groove defined by the first groove and the second groove and has a plurality of wires (20) extended into corresponding recesses at which the depressing blocks apply pressure to the wires for securing the wires in corresponding recesses. Each signal terminal comprises a retention portion (64) disposed in a corresponding recess of the bottom housing and electrically engaging a corresponding wire by insulation displacement connection (IDC), and a tail portion (62) surface mounted to the PCB.
