Abstract
Abstract An electrical connector assembly including a housing, a flexible circuit located within the housing and including first and second terminals thereon, a carriage movably positioned within the housing and designed for having a circuit board inserted therein, actuation means connected to the carriage to cause it to move and occupy first and second positions within the housing, and biasing means in the form of a pair of leaf springs which continuously exert biasing force against the carriage during its positioning within the invention's housing. As defined herein, contact is possible between a plurality of individual contact elements which form part of the circuit board and respective terminals located at one end portion of the flexible circuit. Second terminals located at the other end of the flexible circuit are designed for mating with and contacting respective conductors located on the second circuit device. Positive interconnection is thus possible between high density arrays of contact members in a compact structure.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
247 words
An electrical connector assembly for providing electrical connection between at least one contact element on a circuit board and a corresponding conductor located on a circuit device, said connector assembly comprising: a housing for being positioned adjacent said circuit device and including an opening therein; a flexible circuit member located substantially within said housing and including a first terminal thereon for engaging said contact element on said circuit board and a second terminal thereon electrically coupled to said first terminal and adapted for engaging said corresponding conductor on said circuit device; a carriage movably positioned within said opening within said housing and including a slot therein for having said circuit board located therein, said carriage and said circuit board occupying a first position within said housing wherein said contact element on said board and said first terminal of said flexible circuit member are not engaged, said carriage and said circuit board adapted for moving to a second position wherein said contact element and said first terminal are engaged to provide electrical contact therebetween; actuation means operatively connected to said carriage to cause said carriage and said circuit board to move from said first position to said second position; and biasing means secured to or forming part of said housing for biasing said carriage within said housing in a direction toward said flexible circuit member when said carriage occupies both said first and second positions within said housing and during said movement between said first and second positions.
Claim 2
Dependent Claim
247 words
An electrical connector assembly for providing electrical connection between at least one contact element on a circuit board and a corresponding conductor located on a circuit device, said connector assembly comprising: a housing for being positioned adjacent said circuit device and including an opening therein; a flexible circuit member located substantially within said housing and including a first terminal thereon for engaging said contact element on said circuit board and a second terminal thereon electrically coupled to said first terminal and adapted for engaging said corresponding conductor on said circuit device; a carriage movably positioned within said opening within said housing and including a slot therein for having said circuit board located therein, said carriage and said circuit board occupying a first position within said housing wherein said contact element on said board and said first terminal of said flexible circuit member are not engaged, said carriage and said circuit board adapted for moving to a second position wherein said contact element and said first terminal are engaged to provide electrical contact therebetween; actuation means operatively connected to said carriage to cause said carriage and said circuit board to move from said first position to said second position; and biasing means secured to or forming part of said housing for biasing said carriage within said housing in a direction toward said flexible circuit member when said carriage occupies both said first and second positions within said housing and during said movement between said first and second positions.
Claim 3
Dependent Claim
38 words

Claim 4
Dependent Claim
39 words
The assembly of claim 2 wherein said raised contacting portions engage said first terminal in a wiping motion, said wiping motion occurring in a direction substantially perpendicular to the direction of insertion of said circuit board within said housing.
Claim 5
Dependent Claim
49 words
The assembly of claim 1 including a first pressure exerting member located within said housing adjacent the portion of said flexible circuit member having said first terminal thereon for exerting pressure against said first terminal when said first terminal is engaged by said contact element in said circuit board.
Claim 6
Dependent Claim
28 words
The assembly of claim 4 wherein said pressure exerting member is an elastomeric pad, said housing including a channel therein, said elastomeric pad being oriented within said channel.
Claim 7
Dependent Claim
53 words
The assembly of claim 3 including a second pressure exerting member located within said housing at a spaced location from the first pressure exerting member and adjacent the portion of said flexible circuit having said second terminal thereon for exerting pressure on said second terminal against said corresponding conductor on said circuit device.
Claim 8
Dependent Claim
29 words
The assembly of claim 6 wherein said second pressure exerting member is an elastomeric pad, said housing including a channel therein, said elastomeric pad being located within said channel.
Claim 9
Dependent Claim
21 words
The assembly of claim 3 wherein said second terminal and said corresponding conductor in said circuit device are fixedly secured together.
Claim 10
Dependent Claim
15 words
The assembly of claim 8 wherein said second terminal and said corresponding conductor are soldered.
Claim 11
Dependent Claim
26 words
The assembly of claim 8 wherein said corresponding conductor comprises a metallic pin securely positioned within said housing, said pin passing through said flexible circuit member.
Claim 12
Dependent Claim
