Abstract:
A power supply structure for a multichip package is provided to improve the transmission performance of signals. Cases are fitted onto one face of a ceramic substrate. On the other face are aligned substrates. On each of the substrates are erected I/O pins. The I/O pins are connected to signal pins of LSIs via the ceramic substrate's internal layer. On side faces of the substrates are provided power supply pads. To the power supply pads are connected the power supply pins of the LSIs via the ceramic substrate's internal layer. When power is to be supplied, electroconductive bars are inserted between the substrates. The electroconductive bars supply power to the LSIs via the power supply pads. A cable is connected to one of the I/O pins.
Abstract:
A unitary strip of thermally and electrically conductive spring material is formed with two rows of spring fingers formed at one end which have frictionally engaged therebetween the bus bar or plate of a solid-state device such as an FET having leads soldered to a printed circuit board. The opposite end of the strip is fastened mechanically to a conductive heat sink block on the circuit board. The strip provides electrical power, support for, and heat sinking of the solid-state device.
Abstract:
In a "Futurebus+" backplane, at each end of the backplane the signal lines are each electrically connected to a power bus spaced from the rear face of the backplane via a discrete resistor which is housed in a throughbore in a body of electrically insulating material detachably secured to the rear face of the bakplane and which is electrically connected between the power bus and a pin soldered in a plated through hole and interconnected in the signal line. The ground lines are each connected to the power bus via a discrete capacitor which is housed in a throughbore in the body and which is electrically connected between the power bus and a pin soldered in a plated through hole and interconnected in the ground line. In the event that a resistor or capacitor should be faulty, only the signal or ground line to which the faulty resistor or capacitor is connected will be out of service until the faulty resistor or capacitor is replaced.

Abstract:
An elongated printed circuit (PC) board connector having a plurality of terminal pins aligned in a linear array has attached to its terminal pins an elongated, linear, U-shaped bus bar with a plurality of apertures in its lower edge. A plurality of U-shaped conductors are inserted through respective pairs of edge apertures in the bus bar, with the distal ends of each of the conductors adapted for coupling to a terminal on a PC board upon which the connector is mounted by means of a pair of support columns and nut/bolt combinations. The bus bar, terminal pins and conductor combination is then dip soldered to establish mechanical coupling and electrical connection therebetween. The shorting bus bar electrically couples the conductors to the terminal pins, with each conductor coupled across a plurality of terminal pins which are thus maintained at the same voltage to maintain the bus bar at a constant, uniform voltage over its entire length and to provide this well-defined voltage level to the PC board terminals.

The electrical junction system has a printed circuit board detachably mounted on the wiring board, the printed circuit board generally or inclusively carrying a plurality of circuits incorporating a multiplicity of function parts which are used semi-permanently such as relays and associated control elements.
Abstract:
Each printed circuit board (PCB) on a backpanel has an associated set of power supply studs and power supply pins at an edge of the backpanel. The PCBs can be powered commonly via power supply buses interconnecting the studs. Alternatively, the PCBs can be powered individually via respective power supply PCBs which are inserted into connectors formed partly by the power supply pins and partly by pins on an additional, power supply, backpanel which is mounted to extend contiguously from and in the same plane as the first backpanel. The two arrangements can be combined to power groups of PCBs individually with all of the PCBs in each group being powered commonly.
Abstract:
There is disclosed herein an arrangement for connecting and holding a power distribution bus to a printed circuit board. The bus incorporates flat pads which extend from and are coplanar with it. An oversized hole in each respective pad is provided so that the respective bus may be oriented over an existing plated through hole in the printed circuit board. The leads of an integrated circuit package required to be connected to the voltage or ground potential elements of the power distribution bus are positioned both through the oversized hole of the pad and the plated through hole of the printed circuit board. The connection is made permanent by soldering.
