Abstract

With increasing demand for low-noise, high-density connectors, it has become necessary to introduce ground shielding to the signal pins in electrical contact systems. The Coaxial Compliant Pin Connector is a shielded, high-performance, high-density connector that is inserted into a circuit board by press fit. It requires no solder operation and allows for close center contact spacing.

Coaxial Compliant Pin Electrical Connector

       With increasing demand for low-noise, high-density
connectors, it has become necessary to introduce ground shielding to
the signal pins in electrical contact systems. The Coaxial Compliant
Pin Connector is a shielded, high-performance, high-density connector
that is inserted into a circuit board by press fit.  It requires no
solder operation and allows for close center contact spacing.

      The Coaxial Compliant pin consists of a signal pin 1 with a
compliant press fit section 2 situated at the base of the pin which
is required for the press fit connection to the circuit board signal
PTH.  A dialectric material 3, such as TEFLON*, is molded around the
signal pin 1.  The signal pin 1, with its molded dialectric insulator
3, is inserted into the ground contact 4 which is composed of a
seamless Be Cu tube.

      The assembly is swaged to form the elliptical tube compliant
section 5 required for the press fit connection of the ground contact
4 with the circuit board ground PTH.

      The circuit board 6 is composed of a series of step drilled
holes 7 which are plated to form the copper PTH 8 for the signal and
ground simultaneously.  A secondary drilling or laser operation
severs the connection between the signal PTH 9 and the ground PTH 10.
 In this design, it is not necessary to drill all the way through the
board which allows for more internal wiring.
