Abstract
A television receiver includes a plurality of printed circuit modules bearing signal processing and display producing circuitry. A centralized regulated power supply converts the alternating line power to a number of operating voltages. Individual supply and ground return lead pairs connect each module to the central power supply to the exclusion of the remaining modules. Arc suppression circuitry is provided which includes ground return paths distinct from the supply or ground return leads connecting the modules to the power supply.
Claims6
A television receiver comprising:
- display means including a cathode ray tube susceptible to arcing;
- a centralized regulated power supply defining a first node maintained at a substantially constant first DC voltage and a second node maintained at a second substantially constant DC voltage;
- a plurality of satellite modules, including signal translating circuitry processing signals of varied amplitude and frequency tending to interfere with each other, said circuitry susceptible to being damaged by said arcing;
- support means supporting said modules;
- and
- flexible connecting means, including a plurality of conductor pairs each having a first and second conductor connected to said first and second nodes, respectively, said conductor pairs providing individual operating voltage and isolated ground return connections for each of said modules exclusive of said support means thereby avoiding interference of said signals, minimizing damage to said circuitry, permitting multiple arrangements of said modules.
