Abstract

With ever increasing demands on system performance and the increase in circuit population (circuits per chip per module), the currents are exceeding the capability of today's distribution system. Space available for power is decreasing as the space for circuitry (logic) is increasing. Laminar bus assemblies, as they are used today, cannot be used because of the cross-section that would be required to distribute the logic power.

Power Connector System

       With ever increasing demands on system performance and
the increase in circuit population (circuits per chip per module),
the currents are exceeding the capability of today's distribution
system.  Space available for power is decreasing as the space for
circuitry (logic) is increasing. Laminar bus assemblies, as they are
used today, cannot be used because of the cross-section that would be
required to distribute the logic power.

      A pluggable power connector capable of distributing the
specified logic current, minimizing the voltage drop across the
connector assembly, adapted for plugging with lower
insertion/extraction forces and capable of occupying minimum space
has been designed and is described herein.

      The design, as shown in Figs. 1-5, consists of a housing 1 made
using powder metal technology (copper powder) and plated with
precious metals.  Contact springs 2 are inserted into the housing.
To this housing 1, up to three braided cables 3 are attached,
depending on the current requirements.  One such cable is shown in
Fig. 1.  The housing 1 is plugged onto a T-Bar 4 which is soldered to
a board surface 5.

      The power connector system can be extended to a family of
ratings beginning at 100 amperes through 500 amperes. The connector
housing can be either a straight design or a right angle design.
