IC card and mating socket

Claim 1

An IC card-socket combination comprising: (a) an IC card comprising: (i) a flat, relatively thin housing having an elongated edge along a side of said housing; (ii) a shallow slot formed lengthwise in said edge forming a pair of spaced sidewalls; (iii) a printed circuit member fixedly mounted within said housing, generally aligned with said slot; (iv) at least one active device mounted on said printed circuit member within said housing; (v) said printed circuit member having a border region extending into said slot spaced equally from said sidewalls, said border region providing an edge and upper and lower surfaces; (vi) a row of spaced terminals on at least one of said surfaces of said printed circuit member; and (vii) said card housing embodying spaced separation walls extending from said sidewalls to said upper and lower surfaces of said border region of said printed circuit member to support said border region, said separation walls being located between said terminals on said printed circuit member; (b) said socket comprising: (i) an insulator having an upper surface and a lower surface, an elongated channel in said insulator opening at said upper surface, and adapted to slidably receive therein said side of said card with said elongated edge adjacent to the bottom of said channel; (ii) a row of contacts mounted in said insulator having interconnecting terminals spaced apart a distance corresponding to the spacing of said terminals on said printed circuit member and extending upwardly into said channel and said slot for engaging said printed circuit member terminals; (iii) said interconnecting terminals being recessed within said channel and spaced from the sides of said channel leaving open, unobstructed regions therebetween; (iv) said card sidewalls being disposed in said open regions when said side of said card is mounted in said channel; and (v) said spaced separation walls of said card housing forming cavities therebetween, each adapted to receive therein a corresponding one of said interconnecting terminals of said socket.
