Abstract
A high density, high frequency connector system 10 having first and second mating connector members 12, 70 each member including a multi-row array of signal contact member 52, 102 disposed in columns, each said signal contact member being secured in a respective passageway; a multi-row array of ground contact members 58, 110 disposed between the columns of signal contact members 52, 102 each of the ground contact members 52, 102 having at least a body section secured in a respective profiled slot 42, 94. Each profiled slot 42, 94 has a width selected to be greater than the thickness of the ground body section and means for maintaining the respective ground body sections centered within the respective otherwise wider slot to define air reservoirs of a controlled width on both sides of each ground contact member.
Claims10
A system for establishing an array of ground connections between first and second mating connectors of a connector assembly requiring impedance control, each of said first and second connectors of said assembly including:
- a dielectric housing:
- a multi-row array of signal contact members disposed in columns in said housing, each said signal contact member being secured in a respective passageway thereof;
- a multi-row array of ground contact members disposed in said housing between said columns of signal contact members and between said rows of signal contact members, each of said ground contact members having at least a body section secured in a respective profiled slot, said slot having a width selected to be greater than the thickness of said ground body section;
- and
- means for maintaining said respective ground body sections centered within said respective otherwise wider slot to define air reservoirs of a controlled width on both sides of each said ground contact member, whereby
- the signal contact members may be closely spaced in the connector in a manner necessarily reducing the amount of dielectric housing structure between adjacent signal contact members in a row thereof, and the connector impedance assuredly controlled by precisely defined air reservoirs on each side of each ground contact member.
An improved electrical connector for use in a connector system requiring impedance control, the connector including a housing having a multi-row array of signal contact members disposed in columns thereof, each said signal contact member being secured in a respective passageway of said housing;
- a multi-row array of ground contact members disposed in respective slots within said housing, said ground contact members being positioned between said columns of signal contact members and between said rows of signal contact members, the improvement comprising:
- each said ground contact receiving slot is profiled to receive at least a body section of said respective ground contact member, said slot having a width selected to be greater than the thickness of said ground body section;
- and
- means for maintaining said respective ground body section centered within said respective otherwise wider slot to define air reservoirs of a controlled width on both sides of each said ground contact member, whereby
- the signal contact members may be closely spaced in the connector in a manner necessarily reducing the amount of dielectric housing structure between adjacent signal contact members in a row thereof, and the connector impedance assuredly controlled by precisely defined air reservoirs on each side of each ground contact member.
