Abstract

Provided are terminal-free connectors for flexible interconnect circuits. A connector comprises a housing chamber defined by at least a first side wall and a second side wall oppositely positioned about the base. An edge support is positioned at each of the first side wall and the second side wall. The edge supports allow for precise placement of the flexible interconnect circuit inside the housing chamber. A cover piece is coupled to the base via a first hinge, and is configured to move between a released position and a clamped position. The cover piece includes a clamp portion securing the flexible interconnect circuit against the edge supports in the clamped position. A slider may be configured to move between an extended position and an inserted position within the housing chamber, and may include a convex upper surface configured to urge the flexible interconnect circuit upwards in the inserted position.

First claim

What is claimed is:

1. A connector for connecting to a flexible interconnect circuit, the connector comprising: a base comprising a housing chamber defined by at least a first side wall and a second side wall,
wherein the first side wall and the second side wall are oppositely positioned about the base;
an edge support positioned at each of the first side wall and the second side wall, wherein the edge supports allow for precise placement of the flexible interconnect circuit inside the housing chamber;
a cover piece coupled to the base via a first hinge,
wherein the cover piece is configured to move between a released position and a clamped position,
wherein the cover piece includes a contact surface positioned within the housing chamber in the clamped position, and wherein the contact surface comprises a convex profile; and

a slider configured to move between an extended position and an inserted position within the housing chamber, wherein the slider includes a convex upper surface configured to urge the flexible interconnect circuit upwards in the inserted position.

2. The connector of claim 1 , wherein the first hinge has a ball-in-socket design.

3. The connector of claim 1 , wherein the first hinge is a living hinge formed by a region of thin and flexible plastic.

4. The connector of claim 1 , wherein the flexible interconnect circuit is backed with pressure sensitive adhesive (PSA) to allow the flexible interconnect circuit to be tacked to the edge supports.

5. The connector of claim 1 , wherein the cover piece comprises one or more protrusions, each protrusion configured to interface with a socket within the first side wall or the second side wall to secure the cover piece in the clamped position.

6. The connector of claim 1 , wherein the cover piece includes a clamp portion configured to secure the flexible interconnect circuit against the edge supports in the clamped position.

7. The connector of claim 1 , wherein the slider travels between the extended position and the inserted position within a slider track in the housing chamber, and wherein the slider comprises a protrusion configured to travel within a slider guide located within the first side wall or corresponding edge support to guide the slider between the extended position and the inserted position.

8. The connector of claim 1 , wherein the base comprises one or more blade openings configured to receive blades of a module-side connector to be inserted through the one or more blade openings.

9. The connector of claim 8 , wherein herein in the clamped position, the convex profile of the contact surface is configured to urge the blades inserted through the one or more blade openings downward in the clamped position against the flexible interconnect circuit.

10. A system comprising:
a flexible interconnect circuit; and
a connector comprising:
a base comprising a housing chamber defined by at least a first side wall and a second side wall, wherein the first side wall and the second side wall are oppositely positioned about the base;
an edge support positioned at each of the first side wall and the second side wall, wherein the edge supports allow for precise placement of the flexible interconnect circuit inside the housing chamber;
a cover piece coupled to the base via a first hinge,
wherein the cover piece is configured to move between a released position and a clamped position, and
wherein the cover piece includes a contact surface positioned within the housing chamber in the clamped position, wherein the contact surface comprises a convex profile; and

a slider configured to move between an extended position and an inserted position within the housing chamber, wherein the slider includes a convex upper surface configured to urge the flexible interconnect circuit upwards in the inserted position.

11. The system of claim 10 , wherein the first hinge has a ball-in-socket design.

12. The system of claim 10 , wherein the first hinge is a living hinge formed by a region of thin and flexible plastic.

13. The system of claim 10 , wherein the flexible interconnect circuit is backed with pressure sensitive adhesive (PSA) to allow the flexible interconnect circuit to be tacked to the edge supports.

14. The system of claim 10 , wherein the cover piece comprises one or more protrusions, each protrusion configured to interface with a socket within the first side wall or the second side wall to secure the cover piece in the clamped position.

15. The system of claim 10 , wherein the cover piece includes a clamp portion configured to secure the flexible interconnect circuit against the edge supports in the clamped position.

16. The system of claim 10 , wherein the slider is configured to move between the extended position and the inserted position within a slider track in the housing chamber, and wherein the slider comprises a protrusion configured to travel within a slider guide located within the first side wall or corresponding edge support to guide the slider between the extended position and the inserted position.

17. The system of claim 10 , wherein the base comprises one or more blade openings configured to receive blades of a module-side connector to be inserted through the one or more blade openings.

18. The system of claim 17 , wherein in the clamped position, the convex profile of the contact surface is configured to urge the blades inserted through the one or more blade openings downward in the clamped position against the flexible interconnect circuit.
