<p>The invention is based on the problem how to combine two plugs for connecting digital power circuits and for surge protection, while their chassis remains equal to the chassis according to patent number P-9300570. The new feature is a special construction of printed circuits (1; 17), which are of three-pole type and consist of a central non-conductive layer (34; 38) as well as covering layers (35, 36; 39, 40) on each side, representing conductors a-a' and b-b'. The printed circuits (1; 17) are suitable for accepting and connecting to gas diverters (2; 18), resistors (3, 4; 19, 20), varistors (5, 6; 21, 22), diodes (7, 8, 10, 11; 23, 24, 25, 26, 27), circuit breakers (12, 13; 28, 29) and the grounding terminal (14; 30).</p> |
