Abstract

This article describes an automatic lubrication using a template with lubricant-filled holes. Presently, the components with compliant pins (like connectors) are sprayed with the lubricant to reduce insertion pressure. This wets all parts around the pins of the connector assembly. The lubricant covers also the plastic housing. The lubricant gets lost due to evaporation, and handling of the compliant pin components. The lubricant film may get into the contact area, and difficult cleaning operations are required to eliminate contact problems.

Automatic Lubrication of Individual Compliant Pins

      This article describes an automatic lubrication using a
template with lubricant-filled holes.  Presently, the components with
compliant pins (like connectors) are sprayed with the lubricant to
reduce insertion pressure.  This wets all parts around the pins of
the connector assembly.  The lubricant covers also the plastic
housing.  The lubricant gets lost due to evaporation, and handling of
the compliant pin components.  The lubricant film may get into the
contact area, and difficult cleaning operations are required to
eliminate contact problems.

      A template with the hole pattern representing the compliant pin
pattern of a back plane is placed at the side of the compliant pin
back plane that has to be assembled with components with compliant
pins.  The holes of the template are filled with a lubricant.  The
compliant pins of the components are lubricated as they are pushed
through the template into the back plane.  The template becomes a
part of the back plane assembly, protecting any back plane surface
wiring in addition to the lubrication.  This proposal has the
following advantages:

o   The lubricant can be a grease-like substance.

o   The lubricant can be added into the assembly process prior to
    assembly not contaminating the compliant pin components.

o   The template can be designed so that each compliant pin gets the
    right amount of lubrication (by the template thickness...
