  • Patent number: 7819675
    Abstract: An cable assembly (100) includes an insulated housing (1) extending along a front-to-back direction; a plurality of contacts (2) arranged in a row and supported by the insulated housing, said contacts including three grounding contact members spaced by two pair of signal contact members; a cable (4) including two juxtaposed differential wire pairs (41) respectively enclosed by conductive shielding portions (43); a grounding member (3) including a main portion (31), three finger portions (33) extending forwardly from a front side of the main portion and two arm portions (32) formed at lateral sides of a rear segment of the main portion, said grounding member (3) securely engaged with the cable via the two arm portions thereof griping the conductive shielding portions; and the finger portions soldered to the grounding contact members, and inner conductors of the differential pairs soldered to the signal contact members, respectively.
    Type: Grant

  • Patent number: 6193545
    Abstract: A cable connector 1 adapted to connect a flat cable 5 having plural parallel and alternately arranged signal conductors 51 and grounding conductors 52 retained in position with insulative material 50, includes an insulative pin carrier 20 defining a plurality of holes 211 therein each receiving a conductive pin 23. The holes 211 are arranged in two rows and the pins 23 are alternately received in the two rows. The two rows are separated by a partition along which a groove 25 is defined for receiving two conductive grounding plates 41, 42 therein. A cover 3 is attached to the pin carrier 20 and the flat cable 5 is interposed therebetween. Each of the pins 23 is provided with a bifurcated end 232 to complete insulation displacement of the corresponding signal conductor 51 of the flat cable 5 thereby establishing electrical connection therebetween.

  • Patent number: 6120319
    Abstract: An IDC connector comprises a dielectric housing having mating and connecting faces and an array of passageways defined therebetween. A pair of retaining wedges is formed on opposite ends of the housing. An array of ground and signal terminals is alternately assembled within the array of passageways and each terminal includes an insulation displacement section extending beyond the mating face and a connecting portion received within the passageway. A flat cable having a plurality of ground and signal wires is electrically terminated to the insulation displacement sections of the terminals, respectively. A cover is assembled to the mating face of the housing for attaching the flat cable to the insulation displacement sections extending from the mating face. The cover forms a pair of latches on opposite ends thereof for engagement with the wedges. A grounding device having at least a pair insulation displacement sections electrically connects two conductive wires terminated to the ground terminals.
