Abstract
Abstract An electrical connector for electrically interconnecting conductive pads on a printed circuit board and an electronic package located in an opening in the board and for biasing the electronic package against a cooling substructure on which it rests. More particularly, the connector includes a housing having downwardly extending walls for abutting and biasing the electronic package against the substructure and a plurality of contact elements having spring members which electrically engage respective conductive pads on the electronic package and surrounding circuit board.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
136 words
An electrical connector for electrically interconnecting conductive means on the surfaces of a printed circuit board and an electronic package located in an opening in said circuit board and further with both of said circuit board and electronic package being positioned on a cooling substructure, said electrical connector comprising: dielectric housing means placeable over said electronic package and portions of said circuit board imemdiately surrounding said electronic package; block means extending outwardly from said housing means for abutting and securing engagement with said substructure through said opening in said circuit board; and a plurality of conductive contact means having a pair of diverging spring means, said contact means being disposed in said housing means with said spring means extending outwardly therefrom for electrical engagement with respective conductive means on said circuit board and said electronic package.
Claim 2
Dependent Claim
136 words
An electrical connector for electrically interconnecting conductive means on the surfaces of a printed circuit board and an electronic package located in an opening in said circuit board and further with both of said circuit board and electronic package being positioned on a cooling substructure, said electrical connector comprising: dielectric housing means placeable over said electronic package and portions of said circuit board imemdiately surrounding said electronic package; block means extending outwardly from said housing means for abutting and securing engagement with said substructure through said opening in said circuit board; and a plurality of conductive contact means having a pair of diverging spring means, said contact means being disposed in said housing means with said spring means extending outwardly therefrom for electrical engagement with respective conductive means on said circuit board and said electronic package.
Claim 3
Dependent Claim
19 words
The electrical connector of claim 1 further including wall means in said housing means for engaging said electronic package.
Claim 4
Dependent Claim
18 words
The electrical connector of claim 2 wherein said wall means define slot means for receiving said contact means.
Claim 5
Dependent Claim
22 words
The electrical connector of claim 3 wherein said contact means include strap means attached to and extending between said diverging spring means.
Claim 6
Dependent Claim
16 words
The electrical connector of claim 4 wherein said spring means include first and second spring members.
Claim 7
Dependent Claim
33 words
The electrical connector of claim 5 wherein said spring members include concavo-convex shaped free ends with raised, elongated contact surfaces on the convex surface of said free ends for engaging said conductive means.
Claim 8
Dependent Claim
27 words
The electrical connector of claim 6 wherein said spring members include beams attached to and extending between respective ends of said strap means and said free ends.
Claim 9
Dependent Claim
27 words
The electrical connector of claim 7 further including cooperating retaining means in said slots and on said strap means to retain said contact means in said slots.
Claim 10
Dependent Claim
35 words
The electrical connector of claim 8 wherein said retaining means in said slots include said wall means and said retaining means on said strap means include laterally projecting ears which frictionally engage said wall means.
Claim 11
Dependent Claim
35 words
The electrical connector of claim 9 further including ribs on opposing wall means and notches cut into opposing sides of said strap means which receive said ribs to align said contact means in said slots.
Claim 12
Dependent Claim
36 words
The electrical connector of claim 10 wherein said ears bracket said notches, said ears cooperating with said ribs in said slots to prevent pitch, yaw and rolling motion of said contact means disposed in said slots.
Claim 13
Dependent Claim
33 words
The electrical connector of claim 1 wherein said securing means includes bolts extending through said block means and said substructure and nuts threadably received on said bolts on an underside of said substructure.
Claim 14
Dependent Claim
34 words
The electrical connector of claim 12 wherein said diverging spring means include first and second spring members with each spring member having a concavo-convex shaped free end at the end of an elongated beam.
Claim 15
Dependent Claim
33 words
The electrical connector of claim 13 further including elongated, raised contact surfaces on the convex surfaces of said free ends for engaging said conductive means on said circuit board and said electronic package.
Claim 16
Dependent Claim
35 words
The electrical connector of claim 14 wherein said contact means are compressed as said nuts are tightened onto said bolts, causing said spring members to spread apart with said contact surfaces wiping said conductive means.
Claim 17
Dependent Claim
26 words
The electrical connector of claim 15 wherein said spring members recover upon loosening said nuts whereupon said contact surfaces wipe back over said wiped conductive means.
Claim 18
Dependent Claim
105 words
