Abstract
Abstract Disclosed is a connector for making matched impedance connections, for example, as between two microstrip circuit boards. One-half of the connector has pins located therein with one end of each pin electrically connected to respective signal and ground planes in one microstrip, the second half of the connector has receptacles located therein, the ends of each receptacle mating, or making electrical contact respectively with, signal and ground planes on the second microstrip circuit board. The pins and receptacles are arranged in a pattern such that matched impedance, as between the two connectors, and therefore the two microstrip circuit boards, is effected.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
191 words
An electrical connection for making matched impedance connection between a microstrip circuit board and a coaxial cable conductor, said connector comprising a first housing member connected to said microstrip circuit board and having a plurality of receptacles therein, at least one of said receptacles constituting a signal receptacle and having one end electrically connected to signal circuitry located on one face of said microstrip circuit board, the remaining receptacles being located around said signal receptacle and constituting ground receptacles each having one end electrically connected to ground plane circuitry located on the opposite face of said microstrip circuit board, a second housing member having the end of a coaxial cable connected thereto, said second housing member having a plurality of pins extending outwardly therefrom, only one of said pins constituting a signal pin and having one end thereof electrically connected to the signal conductor in said coaxial cable, the remaining pins being located around said signal pin and constituting ground pins each having one end electrically connected to the ground plane or shield of the coaxial cable, whereby said receptacles will receive said pins allowing for a matched impedance electrical connection.
Claim 2
Dependent Claim
191 words
An electrical connection for making matched impedance connection between a microstrip circuit board and a coaxial cable conductor, said connector comprising a first housing member connected to said microstrip circuit board and having a plurality of receptacles therein, at least one of said receptacles constituting a signal receptacle and having one end electrically connected to signal circuitry located on one face of said microstrip circuit board, the remaining receptacles being located around said signal receptacle and constituting ground receptacles each having one end electrically connected to ground plane circuitry located on the opposite face of said microstrip circuit board, a second housing member having the end of a coaxial cable connected thereto, said second housing member having a plurality of pins extending outwardly therefrom, only one of said pins constituting a signal pin and having one end thereof electrically connected to the signal conductor in said coaxial cable, the remaining pins being located around said signal pin and constituting ground pins each having one end electrically connected to the ground plane or shield of the coaxial cable, whereby said receptacles will receive said pins allowing for a matched impedance electrical connection.
Claim 3
Dependent Claim
182 words
An electrical connection for matching impedance between first and second microstrip circuit boards, each microstrip circuit board having electrically conductive ground plane circuitry located on one side thereof and at least one electrically conductive signal circuit located on the opposite side thereof, said first circuit board having one pin and said second circuit board having one receptacle in electrical engagement with respective signal circuitry thereon, said first circuit board having a plurality of pins in electrical engagement with said ground plane circuitry thereon and in surrounding relationship to said one pin, and said second circuit board having a plurality of receptacles in electrical engagement with said ground plane circuitry thereon and in surrounding relationship to said one receptacle, first and second dielectric housing members in respective engagement with said first and second circuit boards and respectively housing said pins and receptacles, the radial spacing of said pin and receptacle relative to said surrounding plurality of pins and receptacles, and the number of said plurality of pins and receptacles being predetermined so as to achieve a matched impedance connection between said circuit boards.
Claim 4
Dependent Claim
182 words
An electrical connection for matching impedance between first and second microstrip circuit boards, each microstrip circuit board having electrically conductive ground plane circuitry located on one side thereof and at least one electrically conductive signal circuit located on the opposite side thereof, said first circuit board having one pin and said second circuit board having one receptacle in electrical engagement with respective signal circuitry thereon, said first circuit board having a plurality of pins in electrical engagement with said ground plane circuitry thereon and in surrounding relationship to said one pin, and said second circuit board having a plurality of receptacles in electrical engagement with said ground plane circuitry thereon and in surrounding relationship to said one receptacle, first and second dielectric housing members in respective engagement with said first and second circuit boards and respectively housing said pins and receptacles, the radial spacing of said pin and receptacle relative to said surrounding plurality of pins and receptacles, and the number of said plurality of pins and receptacles being predetermined so as to achieve a matched impedance connection between said circuit boards.
Claim 5
Dependent Claim
67 words
An electrical connection as set forth in claim 2 wherein each circuit board and respective connector includes a plurality of signal circuits including respectively, signal pins and receptacles, each respective signal pin and signal receptacle being surrounded by a plurality, respectively, of ground plane pins and sockets, the number of ground plane pins and sockets being determined by the level of crosstalk desired between adjacent signal circuits.
Claim 6
Dependent Claim
36 words
An electrical connection as set forth in claim 3 wherein each signal pin and receptacle of two adjacent circuits share some of the respective surrounding ground plane pins and sockets at the expense of higher crosstalk.
