Abstract
A rack for use in mounting a plurality of input/output modules in a programmable controller or process control computer system or the like has a plurality of first connectors mounted on a circuit board for making detachable electrical connection to the respective modules and has second connector means for connecting the circuit board to the controller system. A rack member molded of a stiffly resilient insulating material has a bottom with apertures therein mounted over the circuit board to permit access to the first connectors and has a pair of juxtaposed integral side walls upstanding from the bottom of the rack to engage respective opposite latteral edges of the modules to guide the modules into respective first connectors in compact side-by-side relation to each other within the rack member. A plurality of latch elements are detachably mounted on the side walls of the rack member so that pairs of the elements are pivoted into latching engagement with respective opposite latteral edges of each individual module as it is inserted into the rack member for holding the module firmly in electrical connection with a first connector, the pair of latch elements being positioned to be manually moved when desired for ejecting individual modules from the rack member.
