Abstract

A triple row coax cable connector providing a pluggable interface between a printed circuit board and a pair of coaxial cables. Signal wires connect to a terminal within the connector after their poly(tetrafluoroethylene) jackets are pushed back by a funnel shaped member. Drain wires are soldered to strain relief bars projecting through holes in a metal plate separating the funnel shaped members.

Claims

1. An electrical connector for coax cable having repeating units of a jacket surrounding a central signal conductor and at least one drain wire exterior to said jacket, said connector comprising

a metal ground plate having first and second ends and a middle portion insert molded to a dielectric member containing an entrance and exit end, said ends separated by adjacent multiple channels each having a diminishing cross sectional area beginning from said entrance end, each said jacket being retained within a channel as each signal conductor is pushed through a channel to contact an electrical terminal exterior to the exit end.

2. An electrical connector according to claim 1 wherein the ground plate is insert molded between a substantially identical pair of dielectric members containing an entrance and exit end, said ends separated by adjacent multiple channels each having a diminishing cross sectional area beginning from said entrance end, each said jacket being retained within a channel as the signal conductor is pushed through a channel to contact an electrical terminal exterior to the exit end.

3. An electrical connector according to claims 1 or 2 wherein the jacket is poly(tetrafluoroethylene).

4. An electrical connector according to claims 1 or 2 wherein a pair of drain wires are located within said cable exterior of said jacket and are soldered to said ground plate.

5. An electrical connector according to claim 2 wherein the signal wire is soldered to the terminal integral with said dielectric member.

6. An electrical connector for a pair of coax ribbon cables containing repeating units of one signal wire surrounded by a jacket and two ground wires enclosed in a metal shield, said connector comprising:

a metal ground plate having first and second ends, and a middle portion insert molded between a pair of dielectric members containing an entrance and exit end, said entrance end and exit end separated by multiple adjacent funnel shaped channels, each said channel adapted to receive a signal wire and its jacket from said coax cable,

the first end of said ground plate having parallel rows of openings for receiving legs from a strain relief bar and the ground wires, the second end of said ground plate having multiple tuning forks for contacting electrical pins,

the exit end of said dielectric members containing slots corresponding to the channels for receiving electrical terminals adapted to receive said signal wire exiting from each channel of said dielectric member, while each jacket is retained within a channel of said dielectric member,

said strain relief bar having at least one latch for engaging a housing shell enclosing said connector.

7. An electrical connector according to claim 6 wherein said jacekt is poly(tetrafluoroethylene).

8. An electrical connector according to claim 6 wherein the dielectric members are molded from polyphenylene sulphide.
