## Abstract

A specialized cable including a compression plug and flexible wiring configured to be connected to a receptacle so that data and/or power signals can be exchanged between the electronic equipment and the device to which the cable is attached. The flexible wiring is a flat set of closely spaced parallel wires separated by insulators (e.g., plastic). The compression plug may include a contact surface (e.g., in an opening or on an exterior surface) that electrically connects to a contact surface in the receptacle. The compression plug may include a sloped or slanted top and bottom in order to facilitate inserting the plug into the receptacle.

## Claims

### Claim 1

A cable comprising:
a compressible compression plug configured to be compressed by interior walls of a receptacle when the compression plug is inserted into the receptacle; and
flexible wiring electrically connected to the compression plug and configured to carry signals from the receptacle when the compression plug is inserted into the receptacle, wherein the flexible wiring is bendable perpendicular to a direction of insertion of the compression plug into the receptacle such that the flexible wiring follows a contour of a bottom side of the compression plug upon an exit of the flexible wiring from the compression plug.

### Claim 2 (depends on 1)

The cable as claimed in claim 1, wherein the cross section of the compression plug at a distal end compared to where the flexible wiring meets the compression plug is smaller than a maximum cross section of the compression plug.

### Claim 3 (depends on 1)

The cable as claimed in claim 1, further comprising an overmold where the flexible wiring meets the compression plug.

### Claim 4 (depends on 1)

The cable as claimed in claim 1, further comprising at least one interlocking nub.

### Claim 5 (depends on 1)

The cable as claimed in claim 1, wherein the compression plug includes a first contact surface in an opening of the compression plug for electrically coupling to a second contact surface in the receptacle.

### Claim 6 (depends on 1)

The cable as claimed in claim 1, wherein the compression plug includes a first contact surface on an exterior surface of the compression plug for electrically coupling to a second contact surface in the receptacle.

### Claim 7 (depends on 3)

The cable as claimed in claim 3, wherein the compression plug is formed of two pieces that retain the overmold in place when the two pieces are connected.

### Claim 8 (depends on 3)

The cable as claimed in claim 3, wherein the compression plug is formed of two pieces that retain the overmold in place when the two pieces are glued together.

### Claim 9 (depends on 7)

The cable as claimed in claim 7, wherein the cross section of the compression plug at a distal end compared to where the flexible wiring meets the compression plug is smaller than a maximum cross section of the compression plug.

### Claim 10 (depends on 8)

The cable as claimed in claim 8, wherein the cross section of the compression plug at a distal end compared to where the flexible wiring meets the compression plug is smaller than a maximum cross section of the compression plug.

### Claim 11 (depends on 7)

The cable as claimed in claim 7, further comprising at least one interlocking nub.

### Claim 12 (depends on 8)

The cable as claimed in claim 8, further comprising at least one interlocking nub.

### Claim 13 (depends on 7)

The cable as claimed in claim 7, wherein the compression plug includes a first contact surface in an opening of the compression plug for electrically coupling to a second contact surface in the receptacle.

### Claim 14 (depends on 7)

The cable as claimed in claim 7, wherein the compression plug includes a first contact surface on an exterior surface of the compression plug for electrically coupling to a second contact surface in the receptacle.

### Claim 15 (depends on 7)

The cable as claimed in claim 7, wherein the compression plug includes a contact surface for connecting to a shell ground of the receptacle.
