Abstract
Abstract An interconnection providing multiple electrical interconnections at a fine pitch can be formed in a pluggable and unpluggable form using multiple connector channels and rows of contact elements in each of a plug and socket. The contacts may be a mixture of active and passive contacts. Furthermore, a contact support structure may provide improve spring characteristics in the contacts. The contacts may be formed in a number of configurations including vertical staggering, alternating or offset patterns, mulit-level tail exit designs, rotated contacts, staggered or nonalign retention features and dedicated power contacts. Anchors or permanent latches, separable latches, and polarization keys may also be utilized. Alternative embodiments may include straddlemount and attachment clip embodiments.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
199 words
An electrical interconnection system comprising: a latch mechanism comprising: an elongated center rail having at least one side, said center rail having first and second ends defining a longitudinal axis therebetween, one or more compressible positioning profiles being disposed on said at least one side of said center rail and being compressible in a direction inward and substantially perpendicular to said longitudinal axis; and an elongated lead in rail extending longitudinally outward from said center rail, said lead in rail configured to guide said latch mechanism into said receiving slot; and a receiving channel adapted to receive said latch mechanism comprising: an elongated receiving slot having at least one side and being adapted to slidably receive said one or more positioning profiles of said latch mechanism, and one or more profile recesses defined in said at least one side of said receiving slot, said one or more profile recesses being adapted to allow said one or more positioning profiles to expand within said one or more profile recesses to secure said one or more positioning profiles within said receiving slot; wherein said latch mechanism and said receiving channel are coupled to respective mating components of said electrical interconnection system.
Claim 2
Dependent Claim
