Abstract

Abstract A connection for flexible circuits permits one or more flexible circuits such as flat flexible cables to be connected to a standard and widely used electrical connector such as a printed circuit board edge connector. The connection includes a substantially rigid flexible circuit structure having a carrier of flat planar configuration with opposed surfaces. A flexible circuit is adhesively bonded to at least one surface with conductive traces of the circuit exposed. Electrical connections are made to the traces by inserting the carrier with attached flexible circuit into a connector having a housing supporting a plurality of terminals with contact portions in a linear array engageable with the exposed conductive traces of the flexible circuit.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 273 words
In an edge card arrangement for electrically connecting conductors of a flat flexible circuit member to a second circuit member including an edge card connector connected to said second circuit member including an elongated dielectric housing with an edge card socket defined therein and a plurality of terminals having one end adapted to electrically mate with the second circuit member and another end adapted to electrically mate with circuits in said flexible circuit member, and a rigidized flexible circuit assembly adapted to be received in said edge card socket including a rigid carrier, a flexible circuit member including a first insulative layer and a plurality of exposed conductors disposed thereon, the flexible circuit member being bonded on said carrier so that the first insulative layer is disposed adjacent a carrier surface and the exposed conductors face away from the carrier, wherein the improvement comprises: an in-line filtered interconnect including: said carrier including a filter circuit having spaced apart first and second contact pads disposed on a major surface thereof; at least one of said flexible circuit conductors overlying and aligned with said first and second contact pads and a portion of said conductor extending between said first and second contact pads being discontinuous; means for electrically connecting said overlying conductor to the first and second contact pads; and at least one of the terminals of the connector electrically engaged to the conductor, whereby a signal travelling along the conductor is transmitted through electrical connecting means to said first contact pad, through the filter circuit to said second contact pad, through connecting means and emerges at the exposed conductor for engagement by the terminal.
Claim 2
Dependent Claim 273 words
In an edge card arrangement for electrically connecting conductors of a flat flexible circuit member to a second circuit member including an edge card connector connected to said second circuit member including an elongated dielectric housing with an edge card socket defined therein and a plurality of terminals having one end adapted to electrically mate with the second circuit member and another end adapted to electrically mate with circuits in said flexible circuit member, and a rigidized flexible circuit assembly adapted to be received in said edge card socket including a rigid carrier, a flexible circuit member including a first insulative layer and a plurality of exposed conductors disposed thereon, the flexible circuit member being bonded on said carrier so that the first insulative layer is disposed adjacent a carrier surface and the exposed conductors face away from the carrier, wherein the improvement comprises: an in-line filtered interconnect including: said carrier including a filter circuit having spaced apart first and second contact pads disposed on a major surface thereof; at least one of said flexible circuit conductors overlying and aligned with said first and second contact pads and a portion of said conductor extending between said first and second contact pads being discontinuous; means for electrically connecting said overlying conductor to the first and second contact pads; and at least one of the terminals of the connector electrically engaged to the conductor, whereby a signal travelling along the conductor is transmitted through electrical connecting means to said first contact pad, through the filter circuit to said second contact pad, through connecting means and emerges at the exposed conductor for engagement by the terminal.
Claim 3
Dependent Claim 35 words
The filtered interconnect arrangement of claim 1 further including a grounded interconnect including: grounding means including a ground plane in said rigidized assembly and at least one of said terminals connected to said ground plane.
