Abstract
Abstract Microstrip transmission of electrical signals between two arrays of signal conductors such as two printed circuit boards is maintained in a right angle electrical receptacle connector (2) in which signal contacts (70,80) are disposed on opposite sides of a central ground bus (90). The signal contacts (70,80) are urged inwardly into engagement with a central dielectric wall (32,34) and the ground bus (90) is similarly urged outwardly into engagement with the same wall (32,34) to establish the microstrip configuration between each row of terminals in the central ground bus (90). The receptacle connector (4) includes a right angle bend and the signal contacts (70,80) as well as the ground bus (90) also have a right angle bend. The insulative housing (10) of the right angle connector (2) comprises upper and lower housing members (12,14) which are snapped into engagement. Resilient arms, forming a part of a connector mounting assembly on the upper housing member (12), engage the lower housing member (14) to hold it in place.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
An electrical connector (2) in which signal contacts (70,80) in at least one row are positioned adjacent a ground bus (90), the signal contacts (70,80) being separated from the ground bus (90) by a dielectric wall (32,34), the connector being characterized by means for urging both the signal contacts (70,80) and the ground bus (90) toward the dielectric wall (32,34) to reduce variations in impedance along the length of the signal contacts (70,80) to reduce the distortion of electrical signals transmitted by the signal contacts (70,80).
Claim 2
Dependent Claim
25 words
The electrical connector (2) of claim 1 wherein two rows of signal contacts (70,80) are positioned on opposite sides of a central ground bus (100,120).
Claim 3
Dependent Claim
145 words
An electrical connector (2) comprising: an insulative housing (10); two rows of signal contacts (70,80) located within cavities (20,22) in the insulative housing (10); a ground bus (90) located within a slot (30) between the two rows of signal contacts (70,80); interior housing walls (32,34) between the slot (30) and the cavities (20,22) in each row along at a portion of the length of the signal contacts (70,80); the electrical connector (2) being characterized by first means on the signal contacts (70,80) for urging the signal contacts (70,80) inwardly toward the ground bus (90) and against an adjacent interior wall (32,34), and second means on the ground bus (90) for urging the ground bus (90) outwardly toward the signal contacts (70,80) into engagement with each adjacent interior wall (32,34) to reduce variations in impedance along the portion of the length of the signal contacts (70,80).
Claim 4
Dependent Claim
45 words
The electrical connector (2) of claim 3 wherein the first means comprises an outwardly directed tab (76,86) engagable with the insulative housing (10) on a side of the corresponding cavity (20,22) opposite from the interior wall (32,34) between the cavity (20,22) and the slot (30).
Claim 5
Dependent Claim
54 words
The electrical connector (2) of claim 3 wherein the ground bus (90) comprises two mating bus components (100,120), the second means comprising at least one protrusion (106,108,110,126,128,130) on one bus component (100,120) engaging the other mating component (100,120) so that both bus components are urged outwardly into engagement with the adjacent interior wall (32,34).
Claim 6
Dependent Claim
131 words
An electrical connector (2) comprising: an insulative housing (10); at least two rows of signal contacts (70,80) in the housing (10), each signal contact (70,80) having a contact mating section (72,82) extending at right angles to a contact lead section (74,84); a ground bus (90) between the rows of signal contacts (70,80), the ground bus (90) having a bus mating section (92) extending at right angles to a bus lead section (94); the connector being characterized in that the ground bus (90) comprises upper and lower components (100,120), at least one of the components having a protrusion (106,108,110,126,128,130) engaging the other component to position each ground bus component closely adjacent one of the rows of signal contacts (70,80) to reduce variations in impedance along the length of the signal contacts (70,80).
Claim 7
Dependent Claim
19 words
The electrical connector (2) of claim 5 wherein the protrusion (106,108,110,126,138,130) is located in the bus mating section (92).
Claim 8
Dependent Claim
22 words
The electrical connector (2) of claim 7 wherein each bus component (100,120) has at least one protrusion, the protrusions (106,108,110,120,128,130) being opposed.
Claim 9
Dependent Claim
27 words
The electrical connector (2) of claim 6 wherein the ground bus (90) has at least two protrusions (106,108,110,120,138,130) spaced apart along the length of the bus (90).
Claim 10
Dependent Claim
31 words
The electrical connector (2) of claim 9 wherein one protrusion (106,108,110,120,128,130) extends transverse to the bus mating section (92) and the other protrusion extends transverse to the bus lead section (94).
