## Abstract

The invention relates to an electrical jumper assembly for connecting electrical circuits. The electrical circuit comprises a flexible cable having one or more conductors which are encapsulated in an insulating material. Each conductor terminates at least at one end in a conductive pad having a hole for mating arrangement with a separate terminal pin. The terminal pin has a contact end which is inserted into the connector hole in the circuitry. The opposite end of the terminal pin extends beyond a stiffener and is preferably hollow which permits swaging the pin to the stiffener. A terminal pin flange located between the ends of the pin rest upon the conductive pad for physical and electrical contact. The flange can be soldered with high temperature solder to the conductive pad for additional stability and reduced resistance.

## Claims

### Claim 1

An electrical jumper assembly, comprising:
a flexible cable having at least one flexible conductor encapsulated in an insulating material, the conductor terminating in a conductive pad, the pad having a contact surface and a non-contact surface and a hole extending from the contact surface to the non-contact surface;
a stiffener member having an outer surface and opposing inner surface and a hole extending from the outer surface to the inner surface, the inner surface of the stiffener facing toward the non-contact surface and being disposed so that the pad hole and the stiffener hole are substantially aligned; and
a separate terminal pin being electrically connected to the conductive pad and extending through the pad hole and the stiffener hole, the pin having a contact end and an opposing non-contact end, the contact end adapted for engaging a female connector and the non-contact end being swaged to the stiffener.

### Claim 2 (depends on 1)

The electrical jumper assembly of claim 1, wherein the non-contact end of the terminal pin defines a cavity.

### Claim 3 (depends on 1)

The electrical jumper assembly of claim 1, wherein a portion of the contact end of the terminal pin is substantially cylindrically shaped.

### Claim 4 (depends on 1)

The electrical jumper assembly of claim 1, wherein the terminal pin has a flange located between the ends, the flange resting on the contact surface of the pad.

### Claim 5 (depends on 1)

The electrical jumper assembly of claim 1, wherein the flexible conductor is ribbon shaped and terminates in a conductive pad at each end.

### Claim 6 (depends on 1)

The electrical jumper assembly of claim 1, wherein the flexible cable includes a laminate structure of a plurality of flexible parallel conductors and a top and bottom insulating layer bonded to opposite sides of the conductors to form a laminated structure.

### Claim 7 (depends on 1)

The electrical jumper assembly of claim 1, wherein the stiffener covers the area of the insulating material where the flexible conductors terminate in conductive pads.

### Claim 8 (depends on 1)

The electrical jumper assembly of claim 1, wherein the terminal pin is secured by being swaged to the outer surface of the stiffener.

### Claim 9 (depends on 4)

The electrical jumper assembly of claim 4, further comprising high temperature solder which adheres to a portion of the flange and the contact surface of the conductive pad.

### Claim 10 (depends on 8)

The electrical jumper assembly of claim 8, further comprising a potted material which forms a protective layer over the swaged portion of the terminal pins.
