Abstract

A plug-in module for supporting therein plug-in circuit boards incorporating electrical components, the module having on the inner surface of its side walls supporting rails for the plug-in circuit boards and suspension rails on one of the external sides for suspending the module in an assembly system, said moudle being a one piece integral unit made of a metalized synthetic material having good shielding characteristics and having the ability to dissipate heat.

Claims

1. A module for supporting printed circuit boards therein comprising:

a top wall, a pair of side walls connected to said top wall, and a bottom wall connected to said side walls;

suspension means fixed to the outside surface of one of said walls for connecting said module into an assembly system;

support means mounted on the inside surface of said side walls for supporting printed circuit boards therein; and

said module comprising an integral one piece unit of synthetic material, said synthetic material being metallized and having graphite incorporated therein.

2. The module of claim 1 wherein

said synthetic material of which said module is constructed is coated with a metallic material.

3. The module of claim 1 wherein

said suspension means comprise a pair of guide rails fixed to said top wall and extending parallel to said side walls.

4. The module of claim 1 wherein

said module is formed with at least one partition wall.

5. The module of claim 1 wherein

said module is formed with one vertical partition wall and one horizontal partition wall.
