ABSTRACT:
The system includes basically the provision of a plastic chassis together with magnetic members for holding electronic components onto the chassis. Such components may comprise transistors, circuit board modules and the like. A preferred application of the system is in the manufacture of television receivers. For each component there is provided a magnetic ring embedded in the plastic chassis or in a heat sink in turn embedded in the plastic chassis. A cooperating collar member of magnetically responsive material mounts a transistor, circuit board module or the like. Asymmetrical plugs and sockets are provided about the outside of the collar and ring respectively so that the transistor or circuit board module can only be inserted in the chassis when in a unique orientation. The collar and magnetic ring in such orientation are precisely aligned to provide full surface contact and thereby hold the component to the chassis and yet permit easy manual removal and replacement without tools.
