Connector shield with integrated ground piercing contact
A connector shield for a flat flexible cable comprises a housing defining a connector space on a first end thereof for receiving a signal cable connector, and a cable space on a second end thereof for at least partially receiving an end of the flat flexible cable. The cable space defines a width greater than that of the connector space and a height less than that of the connector space. A plurality of contact elements extend from the housing and into the cable space for electrically contacting a conductive element of the flat flexible cable.

6. A connector shield for a flat flexible cable, comprising:
a housing defining a connector space on a first end thereof for receiving a signal cable connector, and a cable space on a second end thereof for at least partially receiving an end of the flat flexible cable, the cable space having a width greater than that of the connector space and a height less than that of the connector space; and
a contact element extending into the cable space from the housing for electrically contacting a conductive element of the flat flexible cable, the contact element includes a first pair of opposing substantially L-shaped cantilevered beams having free ends extending in a direction generally parallel to a width direction of the housing.
7. The connector shield of claim 6 , wherein the contact element further includes a second pair of opposing substantially L-shaped cantilevered beams having free ends extending in the direction generally parallel to the width direction of the shield housing.
8. The connector shield of claim 7 , wherein:
the housing includes an upper housing and a lower housing attachable to the upper housing, the upper housing and the lower housing defining corresponding locking features for selectively fixing the upper housing to the lower housing; and
the first pair of opposing substantially L-shaped cantilevered beams are arranged on a first side of the locking features in a longitudinal direction of the housing and the second pair of opposing substantially L-shaped cantilevered beams are arranged on a second side of the locking features opposite the first side.
9. The connector shield of claim 6 , wherein the contact element further includes a generally U-shaped cantilevered arm extending from a rear of the housing and having a free end extending toward the connector space.
10. The connector shield of claim 6 , wherein the first pair of opposing substantially L-shaped cantilevered beams are formed integrally with the housing.
11. A connector shield assembly, comprising:
a flat flexible cable having a signal conductor and a shielding conductor embedded in an insulation material; and
a shield housing including:
an upper shell;
a lower shell attached to the upper shell; and
a contact element extending from and formed with at least one of the upper shell or the lower shell and electrically contacting the shielding conductor of the flat flexible cable through the insulation material.
12. The connector shield assembly of claim 11 , wherein the shielding conductor is exposed in at least one opening formed through the insulation material of the flat flexible cable, the contact element contacting the shielding conductor through the at least one opening.
13. The connector shield assembly of claim 12 , wherein the contact element comprises a first pair of opposing substantially L-shaped cantilevered beams having free ends extending in a direction generally orthogonal to an axial direction of the flat flexible cable.
14. The connector shield assembly of claim 11 , wherein the shield housing further comprises a locking assembly for securing the lower shell to the upper shell.
15. The connector shield assembly of claim 14 , wherein the contact element comprises a first contact element arranged on a first side of the locking assembly in an axial direction of the flat flexible cable, and a second contact element arranged on a second side of the locking assembly opposite the first side.
16. The connector shield assembly of claim 11 , wherein the signal conductor extends into the shield housing a distance greater than that of the shielding conductor in an axial direction of the flat flexible cable.
17. The connector shield assembly of claim 11 , wherein the contact element includes sharpened foil picks extending toward the cable space and into the insulation material from the upper shell and from the lower shell.
18. The connector shield assembly of claim 11 , wherein the contact element includes a plurality of sharpened tines crimped to the flat flexible cable.
19. The connector shield assembly of claim 18 , wherein the sharpened tines electrically contact a ground conductor and the shielding conductor of the flat flexible cable.
20. The connector shield assembly of claim 19 , wherein the sharpened tines are arranged in rows defined on the lower shell, the rows of tines defining a central space therebetween for receiving the signal conductor of the flat flexible cable.
