Abstract

A female connector is adapted for electrically interconnecting the conductors of a flat flexible circuit to the conductors of a complementary mating connecting device. The connector includes a female housing having wall portions defining a cavity for receiving the flexible circuit. The wall portions are relatively movable between an open condition allowing a yieldable backing structure to be assembled on a cavity-side of at least one of the wall portions and a closed condition defining the cavity. The yieldable backing structure resiliently biases the conductors of the flexible circuit received in the cavity against the conductors of the mating connecting device when the connector is mated with the device.

Claims

1. A female connector for electrically interconnecting conductors of a flat flexible circuit to conductors of a complementary mating connecting device, comprising:

a female housing having wall means defining a cavity for receiving the flexible circuit, the wall means including wall portions which are relatively movable between an open condition allowing a yieldable backing structure to be molded on a cavity-side of at least one of the wall portions and a closed condition defining said cavity,

wherein said female housing is generally U-shaped and includes a pair of side wall portions defining opposite sides of the cavity and a rear wall portion defining a rear of the cavity, said rear wall portion including a slot through which the flat flexible circuit passes; and

a yieldable molded-in-place backing structure on said cavity-side of the at least one wall portion for resiliently biasing the conductors of the flexible circuit received in the cavity against the conductors of the mating connecting device when the connector is mated with the device.

2. The female connector of claim 1 wherein said female housing is molded of plastic material and said wall portions are joined by an integrally molded living hinge to provide for said relative movement of the wall portions.

3. The female connector of claim 1, including at least one of said yieldable molded-in-place backing structures on the cavity-side of each of said side wall portions.

4. The female connector of claim 1, including a generally rigid outer shell substantially surrounding the female housing and having an opening aligned with the cavity.

5. The female connector of claim 1 wherein said female housing is molded of plastic material and said side wall portions are joined to the rear wall portion by integrally molded living hinges to provide for said relative movement of the wall portions.

6. The female connector of claim 1, including a generally rigid outer shell substantially surrounding the female housing and having an opening aligned with the cavity.

7. The female connector of claim 1, including latch means operatively associated between said relatively movable wall portions to hold the wall portions in their closed condition.

8. The female connector of claim 1 wherein said female housing includes end wall portions cooperating with said side wall portions and rear wall portion to define a box-shaped structure with a front opening for receiving the flexible circuit.

9. The female connector of claim 8, including latch means operatively associate between at least some of said wall portions to hold all the wall portions in their box-shaped configuration.

10. The female connector of claim 9 wherein said female housing is molded of plastic material and said side wall portions are joined to the rear wall portion and said end wall portions are joined to said side wall portions by integrally molded living hinges to provide for said relative movement of the wall portions.

11. The female connector of claim 10, including latch means operative associated between said end wall portions and said side wall portions to hold all the wall portions in their box-shaped configuration.

12. A female connector for electrically interconnecting conductors of a flat flexible circuit to conductors of a complementary mating connecting device, comprising:

a female housing having wall portions defining a cavity for receiving the flexible circuit, with the wall portions being relatively movable between an open condition allowing a yieldable backing structure to be assembled on a cavity-side of at least one of the wall portions and a closed condition defining said cavity,

wherein said female housing is generally U-shaped and includes a pair of side wall portions defining opposite sides of the cavity and a rear wall portion defining a rear of the cavity, said rear wall portion including a slot through which the flat flexible circuit passes; and

a yieldable backing structure on said cavity-side of the at least one wall portion for resiliently biasing the conductors of the flexible circuit received in the cavity against the conductors of the mating connecting device when the connector is mated with the device.

13. The female connector of claim 12 wherein said female housing is molded of plastic material and said wall portions are joined by an integrally molded living hinge to provide for said relative movement of the wall portions.

14. The female connector of claim 12, including at least one of said yieldable backing structures on the cavity-side of each of said side wall portions.

15. The female connector of claim 12, including a generally rigid outer shell substantially surrounding the female housing and having an opening aligned with the cavity.

16. The female connector of claim 12 wherein said female housing is molded of plastic material and said side wall portions are joined to the rear wall portion by integrally molded living hinges to provide for said relative movement of the wall portions.

17. The female connector of claim 12, including a generally rigid outer shell substantially surrounding the female housing and having an opening aligned with the cavity.

18. The female connector of claim 12, including latch means operatively associated between said relatively movable wall portions to hold the wall portions in their closed condition.

19. The female connector of claim 15 wherein said female housing includes end wall portions cooperating with said side wall portions and rear wall portion to define a box-shaped structure with a front opening for receiving the flexible circuit.
