Abstract

An electrical connector that can be small in size and easy to fabricate is described. The basic design of the connector is shown in the figure. The receptacle, or female side of the connector, is formed by multiple rod-shaped springs with spherical ends; these rods/springs function as fixed cantilever springs which exert multiple contact points on a mating plug, or male pin. The male pin may be straight or tapered with a variety of end geometries in addition to the spherical end of the figure which may be used for retaining the contacts after plugging.

High Density Electrical Connector Structure

       An electrical connector that can be small in size and
easy to fabricate is described.  The basic design of the connector is
shown in the figure.  The receptacle, or female side of the
connector, is formed by multiple rod-shaped springs with spherical
ends; these rods/springs function as fixed cantilever springs which
exert multiple contact points on a mating plug, or male pin.  The
male pin may be straight or tapered with a variety of end geometries
in addition to the spherical end of the figure which may be used for
retaining the contacts after plugging.

      Many possible combinations of pins for different applications
can be used.  The contacts may be constructed with beryllium-copper
or other suitable spring material in a continuous process and may be
plated prior to assembly.

      This connection design has the advantage of redundant, self-
cleaning, self-aligning contacts that do not require compression of
substrates like elastomeric connections.  The terminal lengths may be
relatively short to increase electrical performance.  The connectors
may be surface-mounted and are reworkable.
