## Abstract

The present invention includes a battery pack for a cordless power tool including a plastic housing including a mechanical interface for mechanically coupling the battery pack to a corresponding mechanical interface of a cordless power tool. The mechanical interface includes a rail, a groove and a sliding surface. The battery pack also includes a bracket encased within the plastic housing wherein the bracket includes a first portion positioned within the rail of the mechanical interface.

## Claims

### Claim 1

A battery pack, comprising:
a housing of a plastic material, the housing including a mechanical interface for mechanically coupling the battery pack to a corresponding mechanical interface of a power tool in a first direction,
the housing mechanical interface including a rail, a groove and a sliding surface, the housing rail and the housing sliding surface being opposed to each other on opposing sides of the housing groove,
the housing mechanical interface configured to receive a power tool rail in the housing groove between the housing rail and the housing sliding surface, and
a bracket partially encased within the housing plastic material, the bracket comprising a first portion positioned within the housing mechanical interface rail, the first portion including a wear surface positioned at a lower surface of the housing mechanical interface rail and exposed to the housing mechanical interface groove.

### Claim 2 (depends on 1)

The battery pack, as recited in claim 1, wherein the wear surface moves along an upper surface of the power tool rail.

### Claim 3 (depends on 1)

The battery pack, as recited in claim 1, wherein the wear surface slides along the power tool rail during mating of the battery pack and the power tool.

### Claim 4 (depends on 3)

The battery pack, as recited in claim 3, wherein the wear surface rests on the power tool rail during operation of the power tool.

### Claim 5 (depends on 1)

The battery pack, as recited in claim 1, wherein the wear surface has a lower coefficient of friction that the housing plastic material.

### Claim 6 (depends on 1)

The battery pack, as recited in claim 1, wherein the wear surface reduces friction between the battery pack and the power tool during mating of the battery pack and the power tool.

### Claim 7 (depends on 1)

The battery pack, as recited in claim 1, wherein the wear surface reduces friction between the battery pack rail and the power tool rail during operation of the power tool.

### Claim 8 (depends on 1)

The battery pack, as recited in claim 1, wherein the wear surface reduces wear on the battery pack rail and the power tool rail during operation of the power tool.

### Claim 9 (depends on 1)

The battery pack, as recited in claim 1, wherein the wear surface wicks heat away from the power tool rail due to relative movement of the battery pack and the power tool during operation of the power tool.
