Claim 1
Independent Claim
226 words
An indexing key for use with a circuit board connector strip of the type having an elongate opening for receiving the end of a circuit board, having a series of contiguous locations therealong at which resilient electrical contacts may be placed for electrical/mechanical contact with an inserted circuit board, having indexing slots along the top thereof spaced at predetermined intervals for receiving indexing keys, and having an associated support surface to provide a mechanical connection to a circuit board, the key comprising: (a) a body dimensioned so as to fit in said elongate opening; (b) at least one key arm in association with said body for insertable engagement with an indexing slot; (c) said body comprising an elongate body wherein the bottom of said body is capable of resting on said support surface with said key arm engaged in an indexing slot; (d) said circuit board connector strip further comprising divider walls separating said contiguous locations within said connector strip wherein said elongate body further comprises a pair of leg portions for straddling one of said divider walls when said key is inserted in place in said connector strip; and (e) means integral with said body for causing said body to bear the force of the end of a circuit board being forced thereagainst by way of compression between said support surface and said circuit board.
