Abstract

This is a method for attaching a loadboard to a motherboard or backplane where there are elas- tomer connections on molded housings between the loadboard and motherboard which require compres- sion of the elastomer to achieve conductivity. The standard fastener for the elastomer contacts are screws.

DISTRIBUTED LOADBOARD CLAMP

by Marvin Swapp, James Hopkins and Larry Nickerson

  This is a method for attaching a loadboard to a motherboard or backplane where there are elas- tomer connections on molded housings between the loadboard and motherboard which require compres- sion of the elastomer to achieve conductivity. The standard fastener for the elastomer contacts are screws.

  The new method uses hooks at the location of the fasteners. These hooks are attached to and acti- vated from beneath the motherboard to shafts which are mounted parallel to the contact strips. Pressure is controlled by cantilever springs mounted parallel along the shaft. The shafts are rotated to provide motion to the hooks.

Fig. A The shaft is rotated to 0 deg. for installation/removal of the hook. Fig. B The shaft is rotated to 30 deg. for installation of the load board. Fig. C The load board is placed over the hooks.

Fig. D The shaft is rotated to 120 deg. pulling the hook down into the hole in the connector. The shape of the hook forces it over the edge of the hole in the load board.
