Indexing mechanism for precision alignment of electrical contacts
First Claim
1. An indexing mechanism for electrically engaging a first plurality of connector contacts with a first plurality of contact pads which comprises:
- a substrate having a first surface, said first surface supporting said first plurality of contact pads, said substrate having a periphery and having a notch formed on said periphery;
a first frame formed with a rail;
a body supporting said first plurality of connector contacts, said body being engageable with said rail; and
a post mounted on said body and engageable with said notch to electrically align said first plurality of contact pads with said first plurality of connector contacts;
a second surface on said substrate, said second surface supporting a second plurality of contact pads thereon;
a second frame formed with a second rail;
a second body supporting a second plurality of connector contacts, said second body being slidably engageable with said second rail;
a second post mounted on said second body and engageable with a second notch on said periphery of said substrate; and
means for fastening said second frame to said first frame, thereby securing the electrical alignment of said first plurality of contact pads and said first plurality of connector contacts, and further securing the electrical alignment of said second plurality of contact pads and said second plurality of connector contacts.

Abstract
An indexing mechanism for precision alignment of stacked electronic substrates includes a post associated with a stackable connector and a notch associated with an electronic substrate engaging the connector. The notch is provided to receive the post when the substrate is positioned between two connectors in an assembly thereof. Placement of the post in the notch automatically aligns the electrical contacts of the connector and substrate in their correctly indexed sequence. Connectors can be added to the assembly and additional substrates inserted between any pair of juxtaposed connectors. The indexing mechanism enables precision alignment of any number of substrates in the stacked configuration.

10. A method for aligning a plurality of connector contacts supported by a first stackable connector with a plurality of contact pads supported by a surface of a substrate engaging said first connector, the method comprising:
-
engaging a post supported by said first connector with a notch formed in said substrate to effect a predetermined alignment between said plurality of connector contacts and said plurality of contact pads; stressing said plurality of connector contacts against said surface of said substrate; engaging said plurality of connector contacts with said plurality of contact pads to provide electrical connections therebetween corresponding to said predetermined alignment; securing said first stackable connector in fixed relation to said substrate thereby fixing said predetermined alignment; aligning a second plurality of connector contacts supported by a second connector with a second plurality of contact pads supported by an opposing surface of said substrate engaging said first connector; engaging a second post supported by said first connector with a second notch formed in said substrate to effect a second predetermined alignment between said second plurality of connector contacts and said second plurality of contact pads; stressing said second plurality of connector contacts against said opposing surface of said substrate; engaging said second plurality of connector contacts with said second plurality of contact pads to provide electrical connections therebetween corresponding to said predetermined alignment; and securing said second connector in fixed relation to said substrate and said first connector thereby fixing said predetermined alignment. - View Dependent Claims (11, 12, 13, 14)
