Abstract

This semi-coaxial dual interface connector is designed to permit many insertion cycles of electronic components, and provides an alternative method of surface mounting which allows components to be mounted on both sides of a carrier. Carrier covers can be molded to retain the components. This connector design can be manufactured to a wide variety of sizes to fit adaptable pin types of electronic components.

Semi-Coaxial Dual Interface Connector

       This semi-coaxial dual interface connector is designed to
permit many insertion cycles of electronic components, and provides
an alternative method of surface mounting which allows components to
be mounted on both sides of a carrier. Carrier covers can be molded
to retain the components.  This connector design can be manufactured
to a wide variety of sizes to fit adaptable pin types of electronic
components.

      Individual contact springs 1 (Fig. 2) are retained in a molded
polymer-type base framework 3.  This framework also supports the
semi- coaxial shields 5 that are used to reduce the component
lead-coupled noise and common noise.  The voltage or potential of the
shields is application dependent and may be any level (Va, Vx, Vy)
required by the design. The electrical interaction between the
connector shields and component leads significantly reduces the lead
noise.

      When the shields are electrically connected to the component
leads, they provide additional low inductance current paths which
reduce the effective inductance (Leff) of the connection, and the
electrical noise associated with that Leff, as expressed by the
equation V=Leff (di/dt).  The capacitance between shields of
different voltage levels serves as mid-to high frequency decoupling
capacitance.

      This connector provides an alternative method to surface
mounting in that the component leads are indirectly connected to the
main car...
