Voltage Crossover and Decoupler

A single pluggable unit serves simultaneously to conduct voltages from a bus to a large printed circuit card and as a voltage decoupling device to reduce electrical noise.

Plastic housing 10 has four snap-in, U-shaped contacts 11 for plugging down onto pins on a large card. Discrete wires 12 for connection to the bus are soldered to the top of each contact. In this manner, the standard voltages of +6, +3, -3 volts and ground GND are distributed.

Decoupler contact 13, integral with the bight of each contact 11, comprises an upstanding leg with a contact radius near the end. Decoupler pack 14 is rectangular in shape with four metallized apertures and plugs onto the four upstanding legs. Cap 15 provides a cover for the assembly. Decoupler pack 14 contains three capacitors, one each for the +6, +3 and -3 volt lines. Each capacitor is connected between the ground aperture and one of the other apertures. This arrangement eliminates mounting the decoupling capacitors on the printed circuit card.
