Abstract
Abstract A high density electrical connector system for electrically interconnecting circuits on two or three printed circuit devices. More particularly, the connector system includes matable pin and receptacle connectors with the pin connector mounted on one printed circuit device and the receptacle connector having mounting ears for receiving a heat sink with printed circuit devices attached to one or two opposing surfaces.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
180 words
A high density electrical connector system for electrically interconnecting circuits on printed circuit devices such as backplane, mother boards. daughter cards and the like, said system comprising: first connector means having dielectric module means housed in shell means and a plurality of conductive pin members contained in said module means with first and second ends thereof extending outwardly from opposite sides of said module means with said first ends adapted to engage circuits on a printed circuit device; second connector means having dielectric module means with a plurality conductive contact elements contained therein, said elements having receptacle means at one end for receiving said second ends of said pin members and outwardly extending cantilever beam means at another end for electrically engaging circuits on another printed circuit device so that the two devices may be electrically interconnected; shell means housing said module means of said second connector means, said shell means having a pair of spaced apart ears for receiving a heat sink; and pins, received in each of said pairs of ears, extending through and supporting the heat sink.
Claim 2
Dependent Claim
180 words
A high density electrical connector system for electrically interconnecting circuits on printed circuit devices such as backplane, mother boards. daughter cards and the like, said system comprising: first connector means having dielectric module means housed in shell means and a plurality of conductive pin members contained in said module means with first and second ends thereof extending outwardly from opposite sides of said module means with said first ends adapted to engage circuits on a printed circuit device; second connector means having dielectric module means with a plurality conductive contact elements contained therein, said elements having receptacle means at one end for receiving said second ends of said pin members and outwardly extending cantilever beam means at another end for electrically engaging circuits on another printed circuit device so that the two devices may be electrically interconnected; shell means housing said module means of said second connector means, said shell means having a pair of spaced apart ears for receiving a heat sink; and pins, received in each of said pairs of ears, extending through and supporting the heat sink.
Claim 3
Dependent Claim
23 words
The high density electrical connector system according to claim 1 wherein said pins are received in bushings press-fit in each of said ears.
Claim 4
Dependent Claim
52 words
The high density electrical connector system according to claim 1 wherein printed circuit devices are attached to opposing surfaces of the heat sink and said cantilever beam means extend outwardly from said module means in two rows with a space therebetween to receive the heat sink and printed circuit devices attached thereto.
Claim 5
Dependent Claim
34 words
The high density electrical connector system according to claim 1 wherein some of said pin members of said first connector means include displacing means so that the first and second ends are not coaxial.
Claim 6
Dependent Claim
25 words
The high density electrical connector system according to claim 4 wherein the first ends are on a different pattern and spacing than the second ends.
Claim 7
Dependent Claim
20 words
The high density electrical connector system according to claim 5 wherein the pattern defined by said first ends is chevron-shaped.
Claim 8
Dependent Claim
56 words
The high density electrical connector system according to claim 1 wherein the passages in said module means of said second connector means are arranged in sets of two rows each on each side of the longitudinal center of said module means with said rows of passages in each set being longitudinally displaced relative to each other.
Claim 9
Dependent Claim
78 words
The high density electrical connector system according to claim 7 wherein said cantilever beam means on said contact elements disposed in the outermost rows of passages extend outwardly from said module means at a different angle relative to the cantilever beam means on said contact elements disposed in the innermost rows of passages and with the convex contact areas on all cantilever beam means being located at the same horizontal and vertical planes relative to said module means.
