High frequency electrical connector

摘要

An improved broadside coupled, open pin field connector. The connector incorporates lossy material to selectively dampen resonance within pairs of conductive members connected to ground when the connector is mounted to a printed circuit board. The material may also decrease crosstalk and mode conversion. The lossy material is selectively positioned to substantially dampen resonances along pairs that may be connected to ground without unacceptably attenuating signals carried by other pairs. The lossy material may be selectively positioned near mating contact portions of the conductive members. Multiple techniques are described for selectively positioning the lossy material, including molding, inserting lossy members into a housing or coating surfaces of the connector housing. The lossy material alternatively may be positioned between broad sides of conductive members of a pair.

1. An electrical connector, comprising:
a plurality of conductive members disposed in a plurality of parallel columns of conductive members, each of the plurality of conductive members comprising a mating interface portion, a contact tail, and an intermediate portion electrically coupling the contact tail and the mating interface portion, wherein the plurality of conductive members are arranged in pairs; and a plurality of lossy members, each lossy member being elongated in at least one direction that is parallel to a respective column of the plurality of parallel columns of conductive members and being positioned adjacent the mating interface portions of conductive members in the respective column of the plurality of parallel columns such that the electrical connector is substantially free of the plurality of lossy members between intermediate portions of conductive members of adjacent pairs of the plurality of conductive members, wherein at least one lossy member of the plurality of lossy members comprises a material having a conductivity between 1 siemens/meter and 1×107 siemens/meter.
