Abstract

A connector for a flat flexible cable or flat printed cable includes a housing portion and a plurality of terminals. The housing portion includes a plurality of terminal receiving passageways each receiving a contact portion of one of the plurality of terminals. A plurality of conductors exposed in a window extending through an insulation material of the flat flexible cable are each clamped in a terminating portion of one of the plurality of terminals by a clamping force applied thereon by a cover selectively fixable with respect to the housing portion.

First claim

What is claimed is:

1. A connector for a flat flexible cable, comprising:
a housing having a plurality of terminal receiving passageways;
a plurality of terminals each having a contact portion held in one of the plurality of terminal receiving passageways and an exposed terminating portion; and
a cover selectively fixable to the housing in a clamping position, the cover including a plurality of discrete clamping elements extending therefrom and configured to simultaneously clamp each of a plurality of conductors of the flat flexible cable within a respective one of the plurality of terminating portions when the cover is fixed to the housing in the clamping position, each of the plurality of clamping elements defines a protruding elongated clamping surface which includes a rounded surface for engaging with the conductor, the rounded surface having a radius of curvature defined about an axis extending in a longitudinal direction of a respective one of the plurality of conductors and positioned to engage with one of the plurality of conductors arranged within the terminating portion of the terminal, wherein the conductor is clamped along the longitudinal direction between the clamping surface and an opposing surface of the terminating portion with the cover in the clamping position.

2. The connector of claim 1 , wherein the housing comprises a base defining a plurality of recesses for receiving the plurality of terminals.

3. The connector of claim 1 , wherein the clamping surface of each of the plurality of clamping elements defines a protrusion extending in a direction transverse to the longitudinal direction of a respective one of the plurality of conductors.

4. The connector of claim 1 , wherein each of the terminating portions comprises a generally C-shaped cross-section defining an open side, each of the protruding elongated clamping surfaces is inserted into the open side of the terminating portion along the longitudinal direction of the respective conductor as the cover is placed in the clamping position.

5. The connector of claim 1 , further comprising a locking mechanism for fixing the cover in the clamping position relative to the housing.

6. The connector of claim 5 , wherein the locking mechanism comprises a latch defined on one of the cover or the housing.

7. The connector of claim 6 , wherein the latch extends through a corresponding opening in an insulation material of the flat flexible cable.

8. The connector of claim 5 , further comprising at least one positioning feature defined on at least one of the housing or the cover for aligning the cover with respect to the housing in the clamping position.

9. The connector of claim 8 , wherein the positioning feature comprises a protrusion defined by one of the cover or the housing and a complementary recess defined by the other one of the cover or the housing.

10. The connector of claim 1 , wherein the plurality of conductors are exposed in a window extending through an insulation material of the flat flexible cable, wherein in the clamping position, the cover is configured to engage with the insulation material for fixing the position of the flat flexible cable relative to the housing.

11. The connector of claim 1 , wherein the cover is hingedly attached to the housing.

12. The connector of claim 1 , wherein the cover is removably attached to the housing.

13. The connector of claim 1 , wherein the housing comprises a base defining a plurality of recesses extending in the longitudinal direction of each of the plurality of conductors, each recess receiving a respective one of the plurality of terminals, each of the terminating portions of the plurality of terminals comprises a cross-section having an open side extending in the longitudinal direction of each of the plurality of conductors, the clamping element inserted into the open side in a direction transverse to the longitudinal direction of each of the plurality of conductors as the cover is placed in the clamping position.

14. A connector for a flat flexible cable, comprising:
a first inner housing and a pair of second inner housings separate from the first inner housing, the first inner housing and the pair of second inner housings each having a plurality of terminal receiving passageways;
a plurality of terminals each having a contact portion held in one of the plurality of terminal receiving passageways and an exposed terminating portion, a plurality of segments of the flat flexible cable each have a plurality of conductors exposed in a window extending through an insulation material of the segment, the plurality of conductors of a first segment of the plurality of segments are each arranged in the terminating portion of one of the plurality of terminals in the first inner housing and the plurality of conductors of a pair of second segments of the plurality of segments are each arranged in the terminating portion of one of the plurality of terminals in the pair of second inner housings; and
a first inner housing cover and a pair of second inner housing covers, each of the housing covers selectively fixable to a respective inner housing in a clamping position and including a plurality of clamping elements extending therefrom and configured to clamp each of the plurality of conductors of the flat flexible cable within a respective one of the plurality of terminating portions of the terminals when the covers are fixed to the housings in the clamping positions.

15. The connector of claim 14 , wherein the pair of second inner housings are attached to the first inner housing in an assembled position in which the plurality of terminals are positioned in a pair of rows separated from one another in a direction perpendicular to a longitudinal direction of the plurality of terminals.

16. The connector of claim 15 , further comprising an outer housing having an inner housing receiving passageway receiving the first and second inner housings in the assembled position.

17. A connector assembly, comprising:
a flat flexible cable having an insulation material and a plurality of conductors embedded in the insulation material, the plurality of conductors exposed in a window extending through a portion of the insulation material; and
a connector including a housing and a plurality of terminals, the housing having a plurality of terminal receiving passageways, the plurality of terminals each having a contact portion held in one of the plurality of terminal receiving passageways and an exposed terminating portion, each of the plurality of conductors exposed in the window is clamped in electrical contact with the terminating portion of one of the plurality of terminals by a respective one of a plurality of clamping elements, a clamping surface of each of the plurality of clamping elements comprises a rounded surface for engaging with a conductor in which the rounded surface has a radius of curvature defined about an axis extending in a longitudinal direction of the conductor, further includes an elongated protrusion defining a corresponding elongated clamping surface extending in the longitudinal direction of a respective one of the plurality of conductors and positioned to engage with one of the plurality of conductors arranged within the terminating portion of the terminal, the conductor clamped along the longitudinal direction between the clamping surface and an opposing surface of the terminating portion.

18. The connector assembly of claim 17 , further comprising a cover selectively fixable with respect to the housing, wherein the plurality of clamping elements are defi
