Abstract
Abstract Microstrip transmission of electrical signals between two arrays of signal conductors such as two printed circuit boards is maintained in an electrical connector in which signal contacts are disposed on opposite sides of the central ground bus. Signal contacts are urged inwardly into engagement with a central dielectric wall and a ground bus is similarly urged outwardly into engagement with the same wall to establish the microstrip configuration between each row of terminals in the central ground bus. The receptacle connector includes a right angle bend and signal contacts as well as the ground bus also have a right angle bend. The insulative housing of a right angle connector comprises upper and lower housing members which are snapped into engagement. Resilient arms, forming a part of the connector mounting assembly on the upper housing member, engage the lower housing member to hold it in place.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
An electrical connector in which signal contacts arranged in at least one row are positioned adjacent a ground bus, the signal contacts of said one row being separated from the ground bus by a first dielectric wall, said ground bus comprising two separate mutually opposed members each of which has a blade section, each blade section including: (a) a bus mating section at one end thereof having at least one contact point for mating with a male bus member; and (b) a bus lead section at the other end thereof having at least one lead extending therefrom, at least one of said blade sections having a projection disposed between said contact point and said lead and arranged to engage the other opposed member so that a first of said opposed members is always urged toward and always remains in engagement with said first dielectric wall, thereby reducing variations in impedance and reducing crosstalk along the length of said ground bus.
Claim 2
Dependent Claim
160 words
An electrical connector in which signal contacts arranged in at least one row are positioned adjacent a ground bus, the signal contacts of said one row being separated from the ground bus by a first dielectric wall, said ground bus comprising two separate mutually opposed members each of which has a blade section, each blade section including: (a) a bus mating section at one end thereof having at least one contact point for mating with a male bus member; and (b) a bus lead section at the other end thereof having at least one lead extending therefrom, at least one of said blade sections having a projection disposed between said contact point and said lead and arranged to engage the other opposed member so that a first of said opposed members is always urged toward and always remains in engagement with said first dielectric wall, thereby reducing variations in impedance and reducing crosstalk along the length of said ground bus.
Claim 3
Dependent Claim
78 words
An electrical connector in accordance with claim 1 wherein some of said signal contacts are in a second row and said ground bus being disposed between said tow rows, the signal contacts of said second row being separated from said ground bus by a second dielectric wall, wherein said projection of one opposed member is in said engagement with the other opposed member so that the second of said opposed members is urged against said second dielectric wall.
Claim 4
Dependent Claim
22 words
An electrical connector according to claim 1 wherein a said projection is disposed on the blade sections of both said opposed members.
Claim 5
Dependent Claim
28 words
An electrical connector according to claim 3 wherein said projection of said first opposed member is in mutual engagement with a corresponding projection of said second opposed member.
Claim 6
Dependent Claim
26 words
An electrical connector according to claim 1 wherein said dielectric wall comprises a portion of an insulating housing containing said signal contacts and said ground bus.
Claim 7
Dependent Claim
26 words
An electrical connector according to claim 1 wherein said signal contacts and said ground bus each extend through a right angle bend intermediate opposite ends thereof.
Claim 8
Dependent Claim
40 words
An electrical connector according to claim 6 wherein said dielectric wall comprises a portion of an insulating housing containing said signal contacts and said ground bus and wherein said housing comprises first and second housing members attachable at right angles.
Claim 9
Dependent Claim
53 words
An electrical connector according to claim 7 wherein said insulating housing comprises an upper housing member and a lower housing member, the contact mating section and the bus mating section being disposed within said upper housing member and the contact lead section and the bus lead section extending into said lower housing member.
Claim 10
Dependent Claim
20 words
An electrical connector according to claim 1 wherein said at least one blade section includes multiple projections along its width.
