Plug-in module for electronic device having component forming a guide for aligning the module

Abstract

Abstract A plug-in module for an electronic device includes a header having conductors therein which extend therefrom to form terminals, and a substrate connected to the header and supporting electronic components connected to the conductors. One component has a projecting part which extends through the header and forms a guide to align the module with a socket, to facilitate plug-in of the terminals of the header. The module may be a channel element to control the frequency of a radio device and may include a resonant element, such as a piezo-electric crystal, and a coil for tuning a resonant circuit. The form for the coil may be the projecting part for aligning the module, and also provide access to a core therein for tuning the circuit when the module is plugged into the chassis. The module may include a conducting housing which cooperates with the header to form an enclosed structure. A grounding pin may be provided to establish a ground connection for the circuit on the substrate and for the housing. The grounding pin can extend from the header a greater distance than the terminals, and cooperate with the coil form in aligning the module when it is being plugged into a chassis.
