Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
134 words
In a circuit card shelf, which shelf has a plurality of shelf connectors each having an array of binding posts extending therefrom in a common space pattern with the arrays having common units of spacing therebetween, the combination comprising a program plug non-permanently interconnecting the array of binding posts comprising: a. circuit board, b. a plurality of arrays of conductive sockets of spring material affixed to the circuit board, each socket array spaced to match the common space pattern array of binding said sockets thereby being pressed onto the binding posts of a plurality of shelf connectors and slidably and resiliently engaging the binding posts, and c. printed circuitry on the circuit board electrically interconnecting predetermined ones of the sockets and thereby establishing a desired pattern of interconnections between the array of binding posts.
