Abstract

A connector assembly includes a flexible cable that includes a casing, a plurality of electrical wires each having a first portion encapsulated by the casing and a second portion extending beyond the casing, and a fiber having a first portion encapsulated by the casing and a second portion extending beyond the casing. The connector assembly further includes a housing having a first end to receive the flexible cable and a second end with a connector to connect with another connector, and a circuit board disposed in the housing. The circuit board includes first terminals to connect with the plurality of electrical wires, second terminals to connect with the connector, a plurality of traces coupling respective first terminals with respective second terminals, and a cleat. The second portion of the fiber extends beyond the casing to the cleat and winds around the cleat.

First claim

a plurality of traces coupling respective terminals of the first plurality of terminals with respective terminals of the second plurality of terminals; and
a cleat, wherein the second portion of the fiber extends beyond the casing to the cleat and winds around the cleat.

2. The electrical cable connector assembly of claim 1 , wherein:
the first plurality of terminals is disposed on a first edge of the circuit board; and
the second plurality of terminals is disposed on a second edge of the circuit board, the second edge being opposite to the first edge.

3. The electrical cable connector assembly of claim 2 , wherein the cleat is formed on the first edge of the circuit board and extends away from the first edge.

4. The electrical cable connector assembly of claim 1 , wherein the cleat is an integral part of the circuit board.

5. The electrical cable connector assembly of claim 1 , wherein the second portion of the plurality of electrical wires extends past the cleat towards the second end of the housing and is electrically connected to the circuit board via the first plurality of terminals.

6. The electrical cable connector assembly of claim 1 , wherein the second portion of the fiber is longer than the second portion of each of the plurality of electrical wires.

7. The electrical cable connector assembly of claim 1 , wherein the fiber is a polyester fiber, a nylon fiber, or an aramid fiber.

8. The electrical cable connector assembly of claim 1 , wherein:
the fiber is a first fiber;
the flexible cable further includes a plurality of fibers including the first fiber;
each fiber of the plurality of fibers has a first portion encapsulated by the casing and a second portion extending beyond the casing; and
the second portion of each fiber of the plurality of fibers is wound around the cleat.

9. The electrical cable connector assembly of claim 8 , wherein respective fibers of the plurality of fibers are disposed between adjacent electrical wires of the plurality of electrical wires.

10. An electrical cable connector assembly, comprising:
a circuit board comprising:
a first plurality of terminals to connect with a plurality of electrical wires in a flexible cable;
a second plurality of terminals to connect with a connector;
a plurality of traces coupling respective terminals of the first plurality of terminals with respective terminals of the second plurality of terminals; and
a cleat to receive one or more fibers, the one or more fibers to be wound around the cleat.

11. The electrical cable connector assembly of claim 10 , wherein:
the first plurality of terminals is disposed on a first edge of the circuit board;
the second plurality of terminals is disposed on a second edge of the circuit board; and
the first edge is opposite to the second edge.

12. The electrical cable connector assembly of claim 11 , wherein the cleat is on the first edge of the circuit board and extends away from the first edge.

13. The electrical cable connector assembly of claim 10 , wherein the cleat is an integral part of the circuit board.

14. The electrical cable connector assembly of claim 10 , wherein the one or more fibers are polyester fibers, nylon fibers, or aramid fibers.

15. The electrical cable connector assembly of claim 10 , further comprising a housing having a first end with an opening to receive the flexible cable and a second end with the connector,
wherein the circuit board is disposed in the housing.

16. The electrical cable connector assembly of claim 15 , further comprising the flexible cable disposed in the opening of the housing, wherein the flexible cable comprises:
