Three stage self alignment structure and method
First Claim
1. A three stages self-docking structure receiving and electrically connecting a component, wherein said component carries an electrical connector, said component mounted within a system enclosure wherein the component is supported for operation and including a mating electrical connector in said enclosure comprising:
- coarse positioning means including a pair of guide rails supported by one of said system enclosure and said component and cooperating guideway means, in which said guide rails are slidably received, carried by the other of said system enclosure and said component;
biasing means for urging said component in a direction to maintain engagement between one guide rail and its cooperating guideway means;
intermediate positioning means including a projection on one of said component and said enclosure and a cooperating receiving opening carried by the other of said component and said enclosure with at least one of said projection and said opening including a tapered portion wherein the total taper substantially aligns said electrical connector and the cooperating mating electrical connector from within the tolerance of said coarse positioning means; and
fine positioning means formed as a plurality of tapered surfaces on at least one of said electrical connector and said cooperating mating electrical connector to guide said electrical connectors to an electrically connected condition as said component is guided to the operating position within said enclosure.

Abstract
A structure is shown having three stages for guiding a system component into an operatively mounted position within an enclosure while simultaneously making a blind attachment of the electrical connectors to complete the power and signal circuits between the component and system contained within the enclosure. A coarse positioning structure includes a guide rail means for directing the component toward the operative, mounted position; an intermediate positioning structure functions within the tolerance of the coarse positioning means to substantially align the component including the electrical connectors and a fine positioning means aligns the electrical connectors for the final positioning as the component is latched into the operating position and electrical connections are completed. The three positioning functions are intitated serially.

8. A three stage self docking structure receiving and electrically connecting a component, wherein said component carries an electrical connector, said connector mounted within a system enclosure and wherein the component is supported for operation and including a mating electrical connector in said enclosure comprising:
-
coarse positioning means for confining and guiding said component toward the operatively installed electrically connected position; intermediate positioning means for substantially aligning said component including said electrical connector with the final operating position within the tolerance permitted by said coarse positioning means; and fine positioning means comprising a plurality of tapered surfaces on at least one of said electrical connector and the cooperating mating electrical connector enabling a blind, completed electrical connection of said component to said system in the operating position; and wherein said coarse positioning means comprises two pairs of rails with said pairs of rails disposed at opposite sides of said component and recessed guideway carried by the enclosure in which said component is supported; and
further wherein one of said side rails and one of said recessed guideways are shorter than the other of said rails and said recessed guideways thereby preventing the insertion of said component in an inverted position. - View Dependent Claims (9, 10, 11)

12. A three stage self docking structure receiving and electrically connecting a component, wherein said component carries an electrical connector, said connector mounted within a system enclosure and wherein the component is supported for operation and including a mating electrical connector in said enclosure comprising:
-
a component supporting frame; closely confined entry and loosely confined guide means for guiding said component along a guide surface toward the operatively connected installed position; tapered pin means carried by one of said component and said frame; a pin receiving opening carried by the other of said component and said frame positioned to receive and substantially align said pin within the tolerance of said guide means; and tapered, cooperating connector surface portions respectively carried by said component electrical connector and said system enclosure mating electrical connector which are engagable after said tapered pin is received in said opening in complete the electrical connection;
wherein said guide means comprises pairs of rails mounted on opposite sides of said component and recessed guideways supported on said system enclosure and adapted to receive said rails;
further wherein one of said rails and one of said guideways is shorter than the other of said rails and said guideways and said shorter rail and said shorter guideway cooperate to prevent insertion of said component into said enclosure in an inverted orientation. - View Dependent Claims (13)
