## Abstract

A conductive metal jumper strap has a plate portion with a pair of connection legs forming a u-shape. The connection legs are adapted to connect to terminals to make an electrical connection between two components of a heating device. The plate portion has a bend in it to allow flexing so that the connection legs can make a jumper connection between terminals where the terminal spacing may vary between heating devices.

## Claims

### Claim 1

A conductive metal u-shaped jumper strap comprising:
a) a plate portion having a width, length, and thickness, the plate portion having a bent portion at a middle part thereof, and
b) a pair of connection legs, wherein the plate portion and the connection legs form the u-shape and the connection legs can link to a pair of spaced apart terminals, each connection leg further comprising:
i) an upper leg plate portion extending from the plate portion at a bend; and
ii) a lower connection portion extending from the upper leg plate portion, the lower connection portion having a back and a pair of flexible crimping portions, the back and crimping portions forming a cavity to receive a terminal end for electrical connection purposes;
c) wherein the strap portion can bend so that the connection legs can link to spaced apart terminals with variable spacing by adjusting the amount of bend in the bent portion of the plate portion.

### Claim 2 (depends on 1)

The jumper strap of claim 1, wherein each crimping portions is welded to the upper leg plate portion.

### Claim 3 (depends on 1)

The jumper strap of claim 1, wherein the crimping portions of each lower connection portion are curved flanges extending from the back and terminating with a free end facing the back.

### Claim 4

A method of electrically connecting a pair of terminals together comprising:
a) providing a u-shaped jumper strap having a center plate portion with a bend therein, and a pair of connection legs, the connection legs defining a set terminal spacing;
b) crimping the connection legs to the pair of terminals wherein the bend in the center plate portion is adjusted to accommodate another terminal spacing larger or smaller than the set spacing.

### Claim 5 (depends on 4)

The method of claim 4, wherein each connection leg further comprises:
i) an upper leg plate portion extending from the plate portion at a bend; and
ii) a lower connection portion extending from the upper leg plate portion, the lower connection portion having back and a pair of flexible crimping portions, the back and crimping portions forming a cavity to receive a terminal end of the terminal for electrical connection purposes.

### Claim 6

A conductive metal u-shaped jumper strap comprising:
a) a u-shaped jumper strap having a center plate portion with a first bend therein and a pair of leg portions, each leg portion extending from a second bend, the leg portions defining a terminal spacing; and
b) a pair of terminal connecting portions, each terminal connecting portion extending from a respective leg portion;
c) wherein the first bend in the plate portion is adjustable to vary the terminal spacing so that the terminal connecting portions can attach to terminal connections of different spacings.

### Claim 7 (depends on 6)

The jumper strap of claim 6, wherein each terminal connecting portion is welded to each leg portion.

### Claim 8 (depends on 6)

The jumper strap of claim 6, wherein each terminal connecting portion comprises a back and a pair of flexible crimping portions.
