Abstract
To minimize the weight of a magnetic tape recorder chassis and cabinet assembly, a wire frame chassis (18) carrying printed circuit board guides (20) and connectors (22) is mounted to one side of a sand cast bezel (24), and polyurethane wall panels (16) are secured to the wire frame. A cabinet cover and underlying tape transport assembly are hinged to the bezel to enable pivoting away from the wire frame, exposing circuit boards for servicing. The "open air flow" characteristic of the wire frame chassis (18) helps cool critical electrical components.
Claims14
In a magnetic tape recorder, a light weight chassis and cabinet assembly, comprising
- a rigid bezel;
- a circuit boards support means, including a wire frame carrying opposed pairs of circuit board guides and electrical connector means positioned to be connected to circuit boards supported between said guide pairs;
- first means for supporting said wire frame to said bezel such that said bezel prevents deformation of said wire frame[, said circuit board guides being approximately perpendicular to a plane of said bezel];
- a magnetic tape transport mechanism;
- and
- second means for pivotably supporting said tape transport mechanism to one end of said bezel to enable said mechanism to be pivoted outwardly from said frame.
A light weight chassis and cabinet assembly for electrical equipment, comprising:
- a rigid bezel;
- circuit board support means, including a wire frame carrying opposed pairs of circuit board guides and electrical connector means positioned to be connected to circuit boards supported between said guide pairs;
- at least one wall panel;
- a mounting bracket;
- means for supporting said wire frame to said panel means by sandwiching said wire frame between said wall panel and said bracket;
- and
- means for supporting said wire frame and wall panel to said bezel by securing said mounting bracket to said bezel.
