1. An apparatus comprising:
an electrical connector for providing electrical contact with a corresponding device when the device is inserted into the connector, the device being repeatedly insertable into the connector, the connector comprising: an electrically conductive boundary surface comprising a plurality of first cavities which provide enhanced friction with the device, wherein a particular location of any one of the first cavities does not affect the connector's functionality in providing the electrical contact with the device; a lubricating substance movable on the boundary surface, for providing boundary lubrication for the device, wherein at least a portion of the lubricating substance is disposed within the first cavities; a connector substrate layer comprising a surface with a plurality of second cavities; an electrically conductive barrier layer disposed on the surface of the connector substrate layer, the barrier layer comprising a plurality of barrier cavities, the plurality of barrier cavities being in alignment with the plurality of second cavities, the boundary surface being a surface of the barrier layer, the first cavities being the barrier cavities; wherein the lubricating substance is a fluid; wherein at least a portion of the fluid is trapped within the plurality of first cavities by capillary force; and wherein at least one first cavity has a greater width dimension at a first depth than at a second depth shallower than the first depth and is filled with the lubricating substance. |
