Abstract: A battery pack attachment arrangement comprising a tool having a housing defining a hollow area and an opening into the hollow area. A first support track is defined within the housing hollow area. A battery pack includes a main body and a stem portion extending from the main body. A first key extends radially from the battery pack stem portion. The first key is configured to be received axially through a first keyway and thereafter rotated along the first support track from a first portion to a second portion such that the first key supports the battery pack relative to the housing.

Abstract: A cordless power tool battery pack including an onboard circuit configured to electronically communicate with an associated battery charging system. The onboard circuit communicates information relating to the batter pack to a microprocessor or the like within the battery charging system and charging of the battery pack is controlled based on such communication.

Abstract: A pistol and/or clam shell style power tool housing. With respect to the pistol style housing, the tool housing includes a body defining a head portion with a handle portion depending therefrom to define a forward and/or a rear junction. A metal reinforcing member is configured to span along an inside surface of the body from the head portion to the handle portion such that the reinforcing member bridges either the forward or rear junction. In at least one embodiment, the reinforcing member is provided along each lateral side of the tool body. With respect to the clam shell style housing, with two opposed body halves interconnected to define the tool housing body, at least one continuous reinforcing ring is positioned about both halves of the tool housing body to prevent splitting between the two halves.

Abstract: A battery pack attachment arrangement comprising a tool having a housing defining a hollow area and an opening into the hollow area. A first support track is defined within the housing hollow area. The first support track has a ramped surface extending between a first portion adjacent a first axial keyway and having a thickness t1 and a second portion spaced from the axial keyway and having a thickness t2 which is thicker than the thickness t1. A battery pack includes a main body and a stem portion extending from the main body. A first key extends radially from the battery pack stem portion. The first key is configured to be received axially through the first keyway and thereafter rotated along the first support track from the first portion to the second portion such that the first key supports the battery pack relative to the housing.

Abstract: A circuit board assembly comprising a main board, a connector board, and connector pins. The main board has a first face and a second face and terminating in an edge having a mounting area, the mounting area comprising at least one mounting pad on at least one of the first and the second faces. The connector board having a first face and a second face and comprising at least one through hole between the first and second faces. At least one connector pin is disposed in the at least one through hole and having a portion extending beyond each of the first and second faces of the connector board, wherein the edge of the main board and the second face of the connector board are abutted and the portion of the connector pin extending beyond the second face of the connector board is attached to the at least one mounting pad.
