Abstract

A connector for connecting a flexible interconnect circuit includes a base, having a first set of protrusions and a second set of protrusions. The first set of protrusions and the second set of protrusions are configured to secure the flexible interconnect circuit at a first set of apertures and a second set of apertures of the flexible interconnect circuit, respectively. The first set of protrusions may be positioned at a first distance from the second set of protrusions on the base. The first set of apertures may be positioned on the flexible interconnect circuit at a second distance, greater than the first distance, from the second set of apertures. The base causes the flexible interconnect circuit into an arched configuration when the apertures are secured to the respective protrusions. The connector further includes a cover piece configured to secure the flexible interconnect circuit in the arched configuration.

First claim

The invention claimed is:

1 . An assembly comprising:
a flexible interconnect circuit comprising a first set of apertures and a second set of apertures; and a connector connected to the flexible interconnect circuit, the connector comprising a base and a cover piece, wherein:
the base comprises a first set of protrusions and a second set of protrusions, the first set of protrusions extends into the first set of apertures of the flexible interconnect circuit and secures the base relative to the flexible interconnect circuit, the second set of protrusions extends into the second set of apertures of the flexible interconnect circuit and secures the base relative to the flexible interconnect circuit,
the first set of protrusions is positioned on the base at a first distance from the second set of protrusions,
the first set of apertures is positioned on the flexible interconnect circuit at a second distance from the second set of apertures,
the second distance is greater than the first distance,
the first set of protrusions and the second set of protrusions urge the flexible interconnect circuit into an arched configuration,
the cover piece comprises clamp structures interfacing the first set of protrusions and the second set of protrusions,
the flexible interconnect circuit is positioned between the clamp structures and the base,
the clamp structures directly contact the flexible interconnect circuit, and
the clamp structures secure the flexible interconnect circuit between the clamp structures and the base, thereby securing the flexible interconnect circuit in the arched configuration.

2 . The assembly of claim 1 , wherein:
the clamp structures comprise a first clamp structure and a second clamp structure, the first clamp structure is configured to interface with the first set of protrusions to secure the flexible interconnect circuit in the connector, and the second clamp structure is configured to interface with the second set of protrusions to secure the flexible interconnect circuit in the connector.

3 . The assembly of claim 1 , wherein the base further comprises side walls configured to guide the positioning of the flexible interconnect circuit within the base.

4 . The assembly of claim 1 , wherein:
the cover piece is coupled to the base via a hinge, and the cover piece is configured to move about the hinge between an open position and a closed position.

5 . The assembly of claim 1 , wherein:
each aperture of the first set of apertures has a first shape corresponding to a first cross-sectional geometry of each protrusion of the first set of protrusions, each aperture of the second set of apertures has a second shape corresponding to a second cross-sectional geometry of each protrusion of the second set of protrusions, and the first shape is different from the second shape.

6 . The assembly of claim 1 , wherein at least one of the clamp structure extends across a width of the base from one aperture to another aperture in at least one of the sets of apertures.

7 . The assembly of claim 1 , wherein the first set of apertures and the second set of apertures are positioned on strips of material positioned on opposite sides of the flexible interconnect circuit, wherein the strips are monolithic with material of the flexible interconnect circuit.

8 . The assembly of claim 1 , wherein at least one of the clamp structures comprises a surface extending medially toward an area between the two sets of protrusions urging a portion of the flexible interconnect circuit located between the two sets of protrusions downward, thereby increasing a height of the arched configuration.

9 . The assembly of claim 1 , further comprising one or more blade openings configured to receive one or more blades of a module-side connector.

10 . The assembly of claim 9 , wherein the one or more blade openings are positioned through the cover piece.

11 . The assembly of claim 9 , wherein the arched configuration of the flexible interconnect circuit is configured to urge a conductive surface of the flexible interconnect circuit against the one or more blades of the module-side connector.

12 . The assembly of claim 9 , wherein the cover piece comprises a contact surface having a surface geometry that is configured to urge the one or more blades of the module-side connector against the flexible interconnect circuit.

13 . The assembly of claim 9 , wherein the one or more blade openings are positioned between the clamp structures.

14 . The assembly of claim 9 , wherein a height of the arched configuration of the flexible interconnect circuit, before the one or more blades are inserted into the blade openings, is positioned above a height of male blades inserted into the blade openings.
