Claim 1

Independent Claim 238 words

A multi-contact electrical connector for connecting terminal pads of a ceramic substrate package to corresponding terminal pads on a printed circuit board, said connector comprising: at least two terminal strip members, each said strip member having a plurality of terminals of resilient spring metal and two webs of insulating material, said terminals extending in spaced, parallel side-by-side relationship bonded between said webs of insulation material, said terminals being reversibly formed with respect to the axis of said strip members through an angle of substantially 180° intermediate the ends thereof forming two legs, each of said terminals constituting a resilient contact spring, the ends of the legs of each of said terminals being exposed from said insulation webs and forming first and second contact zones adapted for engagement with said ceramic substrate and said printed circuit, respectively, said contact terminal strip members being mounted on a printed circuit board extending normal to the plane thereof and defining therebetween a configuration for receiving therein a ceramic substrate package, and a hollow metal housing shell of like configuration received about the outside of said members and serving as a reaction surface for said members when said ceramic substrate is received therein, whereby upon mounting said members on the printed circuit board in parallel oppositely directed rows the terminal pads of the package engage the free ends of the terminals with sufficient force being generated therebetween to form an effective electrical connection.

Claim 2

Dependent Claim 238 words

Claim 4

Dependent Claim 191 words

An electrical connector in combination with a printed circuit board for electrically connecting a ceramic substrate package thereto, said connector comprising: at least two terminal strip members each having a plurality of parallel spaced relilient spring terminals bonded between webs of flexible insulative material covering at least a intermediate portion of both sides of each of said terminals, said terminals being reversibly formed with respect to the axis of said terminal strip member through an angle of substantial 180° intermediate the ends thereof, one free end of each said spring terminal being bent substantially normal to the axis of said terminal strip member and secured to a respective pad of said printed circuit board so that said terminal strip member is substantially upwardly free standing from said circuit board, said terminal strip members being secured to said circuit board defining therebetween the profile of a ceramic substrate package to be engaged thereby, and a hollow metal housing shell loosely received over the upper free ends of said terminal strip members and serving as a reactive surface for said spring terminals and being insulated therefrom by one of said layers of insulation.

Claim 5

Dependent Claim 191 words

An electrical connector in combination with a printed circuit board for electrically connecting a ceramic substrate package thereto, said connector comprising: at least two terminal strip members each having a plurality of parallel spaced relilient spring terminals bonded between webs of flexible insulative material covering at least a intermediate portion of both sides of each of said terminals, said terminals being reversibly formed with respect to the axis of said terminal strip member through an angle of substantial 180° intermediate the ends thereof, one free end of each said spring terminal being bent substantially normal to the axis of said terminal strip member and secured to a respective pad of said printed circuit board so that said terminal strip member is substantially upwardly free standing from said circuit board, said terminal strip members being secured to said circuit board defining therebetween the profile of a ceramic substrate package to be engaged thereby, and a hollow metal housing shell loosely received over the upper free ends of said terminal strip members and serving as a reactive surface for said spring terminals and being insulated therefrom by one of said layers of insulation.

Claim 6

Dependent Claim 37 words

An electrical connector according to claim 3 further comprising: means grounding said shell to said printed circuit board whereby loss of signals at high frequency is reduced by matching the impedance of the source and the load.

Claim 7

Dependent Claim 31 words

An electrical connector according to claim 3 further comprising: a bump formed on one folded portion of each said terminal directed towards the adjacent folded portion and serving for overstress compensation.

Claim 8

Dependent Claim 216 words

A multi-contact electrical connector for connecting terminal pads of a ceramic substrate package to terminal pads of a printed circuit board, said connector comprising: at least one pair of terminal strip members, each said strip member having a plurality of terminals of resilient spring metal bonded between bonded between two webs of insulating material, said terminals extending in spaced parallel side-by-side relationship with the ends thereof exposed forming first and second contact zones adapted to engage said package and said board, respectively, said terminals being reversibly formed upon themselves with respect to the axis of said strip through an angle of substantially 180° intermediate the ends of the terminals, said second contact zones being bent substantially normal to the plane of said members and secured to a printed circuit board extending normal to the plane thereof and defining a configuration for receiving the ceramic substrate package, and a hollow housing shell received about the upper outer ends of said members and serving as a reaction surface for said members when said ceramic substrate is received therein, whereby upon mounting said members on the printed circuit board in parallel oppositely directed rows the terminal pads of said package engage the free ends of the contacts with sufficient force being generated to form an effective electrical connection therebetween.

Claim 9

Dependent Claim 216 words

A multi-contact electrical connector for connecting terminal pads of a ceramic substrate package to terminal pads of a printed circuit board, said connector comprising: at least one pair of terminal strip members, each said strip member having a plurality of terminals of resilient spring metal bonded between bonded between two webs of insulating material, said terminals extending in spaced parallel side-by-side relationship with the ends thereof exposed forming first and second contact zones adapted to engage said package and said board, respectively, said terminals being reversibly formed upon themselves with respect to the axis of said strip through an angle of substantially 180° intermediate the ends of the terminals, said second contact zones being bent substantially normal to the plane of said members and secured to a printed circuit board extending normal to the plane thereof and defining a configuration for receiving the ceramic substrate package, and a hollow housing shell received about the upper outer ends of said members and serving as a reaction surface for said members when said ceramic substrate is received therein, whereby upon mounting said members on the printed circuit board in parallel oppositely directed rows the terminal pads of said package engage the free ends of the contacts with sufficient force being generated to form an effective electrical connection therebetween.
