Connector

Claim 1

An improved connector comprising: a first rectangular, generally flat connector housing section having adjacent module-receiving recesses in a module-receiving face at an end of said first housing section, a plurality of spaced, removable connector mating tabs attached to and protruding outwardly along a mating surface of said first housing section, a second rectangular, generally flat connector housing section having a plurality of selectively openable notches spaced along and extending into a mating surgace thereof, said notches having a bridge member blocking access to said notches when not selectively opened, said notches being spaced so as to correspond to the spacing of said removable connector mating tabs, each of said module-receiving recesses having a specially prepositioned notch in an interior surface thereof, the relative position of each notch with respect to its associated recess being different than the positions of the other notches in other recesses of said first connector housing section, said notches providing keys for ensuring proper placement of a module in a predetermined recess for receiving that module, said module having a prepositioning tab for insertion into said prepositioned notch, a plurality of modules capable of holding electrically conductive pins and sockets therein in predetermined patterns, said modules being mounted in said module-receiving recesses located in said first connector housing section, a plurality of spaced, selectively removable module keying tabs protruding laterally outwardly from an outer surface of said modules at a mating end of said modules, said module-receiving recesses having selectively openable keying notches in an inner surface near said mating surface of said first housing section, said notches spaced so as to correspond to the spacing of said module keying tabs, one face of each said module-receiving recess further having a U-shaped opening oriented toward said respective mating surfaces, with a housing wall portion defined by the center of said U-shape constituting a module locking tab, wherein said side wall through which said U-shaped opening extends is of reduced thickness in a region between said U-shaped opening and said mating surface, and wherein a first portion of said module locking tab is of like reduced thickness, a second portion of said tab hiving a gradually increasing thickness toward the end of the tab, at which said thickness is substantially equal to an unreduced housing wall thickness, and wherein each said module has a protruding transversely oriented bar on an outer face, positioned so as to engage and lock beyond said locking tab when said module is inserted in its proper recess, the thickness of said bar being at most equal to the amount by which said housing wall thickness is reduced in said reduced thickness regions.
