Abstract

A system for handling variable digital information comprising a key having an active integrated circuit component with leads extending therefrom, a battery for powering the component, unplated leads extending from the component to both the battery and to one edge of the key, and a container for sealing the component, battery and leads except at the edge of the container; and a receptacle having a plurality of unplated leads couplable at their inboard ends to electronic machinery and couplable at their outboard ends to the leads at the edge of the container.

Claims

1. A system for handling variable digital information comprising:

a portable self-contained electronics package having an electrically insulating base with a leading edge at one end thereof formed with recesses and with a longitudinal axis along the length thereof, an active integrated circuit component positioned within the base unplated, discrete, electrically conductive, non-compliant members having male contacts secured within the recesses at the leading edge and extending between the component and the leading edge, the male contacts being shaped to facilitate sliding contact with associated contacts, the male contacts having upper contact surfaces located in a plane of contact, the package also including a container for sealing the component and non-compliant members except adjacent to the leading edge; and

a receptacle having an electrically insulating support with an outboard end having recesses formed therein and a longitudinal axis along the length thereof parallel with the axis of the base, the receptacle also having a plurality of unplated, discrete, electrically conductive, compliant members having female contacts secured within the recesses at the outboard end and with inboard portions couplable to electronic machinery and with the female contacts having lower contact surfaces slidingly, resiliently contactable with the upper contact surfaces of the male contacts, the compliant members adapted to urge the lower contact surfaces downwardly toward the plane of contact into sliding, resilient contact with the upper contact surfaces of the male contacts whereby, when the base is moved along its axis into sliding contact with the outboard end of the support, high normal forces are generated between the male contacts and female contacts to break corrosion existing on the contacting surfaces thereof.

2. The system as set forth in claim 1 wherein the compliant members include bends to form acute angles.

3. The system as set forth in claim 1 wherein the high normal forces are at least about 200 grams.

4. The system as set forth in claim 1 wherein the non-compliant members are down turned at the leading edge of the base.

5. The system as set forth in claim 1 and further including means to preclude inserting the electronics package into the receptacle in an inverted orientation.
