Electrical Connector for Flat Flexible Cable

A connector for attaching a circuit board at its edge to a flat flexible cable utilizes the cable itself as the connector contact.

A clamp member 10 (Fig. 1) receives the cable 12 and has a longitudinally extending channel characterized by a narrow throat 14 that extends from an open end to an enlarged closed chamber 16. Compressible pads are located on the throat walls.

In use, a section flexible cable 12 is looped into the throat 14 and tends to bulge out at the bend that occurs within the enlarged chamber 16, making removal difficult. The section of cable 12 extending into the clamp is formed with one insulating layer 18 removed on the inside of the fold, so as to expose the individual conductors 20. A circuit board end 22 having conducting lands 24 corresponding to the conductor positions of conductors 20 is forced into the throat section and makes intimate engagement with the conductors 20 as a result of the pressure exerted by a pair of compressible pads 26. The circuit board can be removed from the clamp without dislodging the flexible cable because the bulge of cable 12 located in the enlarged chamber 16 strongly resists the compression required to negotiate the narrow throat 14 of the clamp member 10. Flexible fingers 28 may be formed on the clamp member 10 to facilitate mounting, and it is preferred to include extensions 30 on the circuit board end 22 to assure lateral alignment of conductors 20 and conductin...
