Electronic module package and mounting having diagonally disposed guide pins and threaded rods

摘要

Similar electronic module packages are provided having guide pins and front actuated retaining rods for mounting the package on a mounting panel having threaded mounting holes spaced in a regular pattern to accept the guide pins and retaining rods of several module packages. The guide pins and retaining rods are mounted on diagonally opposite corners of the modules. Front mounting of the modules and front location of electrical connectors avoids a requirement for rear access to the mounting panel. Various arrangements of modules on the mounting panel are allowed by suitable arrangement of the pattern of mounting holes in the panel. The modules include a housing with a face plate and a mounting plate. The housings include either a support panel or a cover. The face plate and the mounting plate extend above and below the support panel or the cover.
